Product Description Chinese liquid soil stabilizer, rock forming agent, road solidification Rammed earth wall solidification agent rammed earth technology rammed earth wall solidification agent rammed earth wall Adding cement Type A soil stabilizer JUSTSOLID ® technology manual I . Product introduction 1.1 Definition of soil stabilizer Soil stabilizer is a new type of environmental protection curing material, which acts directly on the soil to solidify the soil into a dense, uniform, high strength and durable composite stabilized soil layer. Composite stabilized soil is a semi-rigid material formed by new engineering material soil stabilizer and soil stabilization. Compared with the commonly used inorganic combined stabilized materials, the composite stabilized soil can achieve local materials, and has the characteristics of convenient construction, short construction period, low cost and excellent technical indicators for road use. In a certain range, it can replace the commonly used gravel, crushed stone, reduce the amount of lime and other inorganic binding materials, thus reducing the project cost, saving resources, saving energy, and conducive to ecological environmental protection. This technology is used in the construction and repair of composite stabilized soil subbase and base of new and reconstructed highway engineering, as well as pavement construction, wall construction and repair of different purposes. It has broad application prospects in municipal, transportation, water conservancy, foundation treatment and other projects. 1.2 Classification of soil stabilizer In CJJ/T286-2018 Technical Standard for the Application of Soil Solidifying Agent, the soil solidification agent is divided into Class A soil solidification agent and Class B soil solidification agent. Class A soil stabilizer: a powder or liquid additive that can improve the engineering performance of the foundation soil by physical or chemical reaction with cement (or lime and other cementitious materials), soil, water and air after being added into the soil. Class B soil stabilizer: after being added into the soil, it is a soil stabilizer that can be used alone through the physical or chemical reaction with soil, water and air, not mixed with cement (or lime and other cementitious materials), and a powder additive that can improve the engineering performance of the foundation soil. II. Physical and chemical properties Form: liquid or granular powder Solubility: soluble in water Type: ionic polymer type biological enzyme type Safety: ecological and environmental protection III.　Action mechanism The working principle of composite stabilized soil is to make the surface current of soil micelle reduce energy and fix a large amount of free water in the soil in the form of crystal water. The engineering properties of the soil are changed by a series of physical and chemical reactions after the soil stabilizer is mixed with the soil. The particles tend to agglomerate, the electrolyte concentration increases, and the volume expands to further fill the soil pores; Under the action of compaction, the whole structure is formed to make the solidified soil easy to be compacted and stable, reach the compactness that cannot be achieved by conventional methods, and improve its strength, compactness, modulus of resilience, deflection value, CBR, shear strength and other properties, so as to meet the requirements of road technical indicators. IV.Adaptability and scope of use Soil stabilizer can be applied to a variety of soil properties, such as clay, silt and sand; Mineral powder, slag, construction waste, etc. According to different soil properties, different curing schemes are formulated by adjusting the material ratio. 1. Subgrade construction The subbase of the expressway is hardened, and the base and subbase of the first class road and below are hardened. Hardening of base course and surface course of simple road or temporary road. Cement soil, soft soil and soft foundation solidification. 2. Site hardening Hardening treatment of parking lot, road, stockyard, storage yard, drilling well pad, production and processing yard, etc. 3. Rammed earth wall Vegetable, flower and breeding greenhouse; Construction or repair of ancient building walls; Earth wall of folk houses, etc. 4. Making unburned bricks After fully mixing the clay with the soil curing agent, it is supplemented with other hydraulic materials and directly pressed by the brick press. V. Construction plan 5.1 Basic Requirements ① Cementitious material: cement. It shall comply with the current national standard General Portland Cement (GB175). Cement of the same grade, brand, variety and delivery shall not be mixed. Cement grade 425 and above. The initial setting period is required to be more than 3 hours, and the final setting period is about 6 hours, not more than 10 hours. ②Water quality requirements: the water shall be non-polluting water (potable water for livestock). It conforms to the current industrial standard Standard for Concrete Water JGJ 63. ③ Construction thickness: the compaction thickness of each layer should be 15-20 cm (cm), and the total compaction thickness should be determined according to the construction requirements. ④ Addition of cementitious materials: the amount of cementitious materials generally accounts for 3% - 6% of the total soil amount. The details shall be determined according to the construction requirements and process. ⑤ Amount of soil stabilizer: about 0.5 kg per cubic meter of compacted earth; It is about 0.03% (three thousandths) of the mixture by weight. Curing agent for sealing layer: after curing, spray on the surface of solidified soil, dilute with water about 20 times, and spray the sealing layer. ⑥ Moisture determination method: Liquefied Road Soil Stabilizer Rammed Earth Wall Solidification Agent 0 Liquefied Road Soil Stabilizer Rammed Earth Wall Solidification Agent 1 Figure1 Soil moisture meter Figure2 Traditional simple method Use a soil moisture meter or traditional simple method: grab a handful of soil, put it in your hand and hold it tightly, and the soil mass will be formed without scattering; One meter from the ground, let the soil mass fall freely, and the soil mass spread evenly (fall to the ground and blossom), indicating that the moisture content is about 15%. ⑦ Material consumption: For example, the area of the soil to be solidified is calculated as 5 square meters, the thickness is 20 cm, and the total volume is 1 cubic meter after compaction. The density after compaction is calculated as 2 tons/cubic meter, and the total volume is 2 tons. *Earthwork=area * thickness=5 square meters * 0.2 meters=1 cubic meter * Total soil volume=earthwork * compaction density=1 * 2=2 tons; *Amount of cementitious material (cement)=total soil quantity * 10%=2 * 10%=0.2 tons； *Amount of soil stabilizer=total earthwork * amount of soil stabilizer=1 m3 * 0.5 kg/m3=0.5 kg; *Water consumption of diluting and curing agent=(optimum moisture content * total solid content) - (initial soil moisture content * total soil content) =18% * (soil volume+cement+diluted water) - 12% * total soil volume Note: In the formula, the initial water content of soil is calculated as 12%, and the optimum water content is calculated as 18%; The specific construction shall be subject to the actual water content.

Martin, a purchaser of American company PowerTeam, sent an email last week saying that he saw on the Internet that AAK was a hydraulic valve supplier of some European hydraulic pump companies. He wanted to know whether the quality of AAK could match the quality of the hydraulic valve produced in the United States he was currently using. I directly answered that the quality of hydraulic valves in the United States should also be in different levels, you can have a small try and compare them with your hydraulic valves purchased in the United States. Martin frankly told about his current purchasing status. He needed to re- purchase a batch of hydraulic sequence valves for hydraulic pumps. After placing an order with the original manufacturer in the United States, the manufacturer told him that there were not enough labor for mass production at this moment. He had to wait for 3 months at least. The boss was not satisfied with his purchasing arrangement and asked him to find a new supplier of hydraulic sequence valve and complete production within 2 months. Martin is a little embarrassed because this hydraulic sequence valve has particularly high requirements for various accuracy. In the early stage of development 3 years ago, he contacted more than 20 hydraulic valve manufacturers, compared and tested the hydraulic sequence valves from them, and only the samples from the local hydraulic valve manufacturer in the United States met the requirements. Martin saw the information of AAK to found that it was actually the supplier of hydraulic pumps in Europe. After browsing AAK website (www.aakindustry.com), he felt that AAK hydraulic valve might become his supplier. According to the drawings and working conditions of his hydraulic sequence valve, we found that it does have high requirements for the accuracy of the hydraulic sequence valve. I told Martin that we need 15 days to make and test samples. After the samples of the hydraulic sequence valve pass the test, we will discuss the order at that time. 10 days after the hydraulic sequence valve sample was sent, Martin emailed AAK that the hydraulic sequence valve fully met the production requirements of the existing hydraulic pump. At the same time, the engineers of PowerTeam also applauded every detail of AAK hydraulic sequence valve sample, which was no worse than that of the American company. In particular, some core parameters, such as the matching surface roughness of AAK hydraulic sequence valve spool and valve hole, can reach Ra value of 0.1 ~ 0.2μm. The surface roughness Ra value of the outer circle of the valve spool is 0.1μm. The Ra value of the inner circular surface of the valve hole is 0.2μm. Some parameters are even higher than those of his original American manufacturer, including 100% burr removal. Martin was surprised how AAK hydraulic sequence valve achieve these? AAK hydraulic valve has two absolute advantages and has already surpassed its domestic counterparts. It is uncertain whether it has surpassed its American counterparts. 1. AAK has a high-precision CNC machining center imported from Switzerland and independent fixtures upgraded and refitted by itself, eliminating human errors. 2.The independent professional R & D team cooperates with the unique R & D technology to realize the personalized customization demand of hydraulic valve accuracy, which can not be achieved by 95% of domestic peers. When Martin got the quotation of AAK hydraulic sequence valve, it was 23% cheaper than that produced locally in the United States, but the quality was no worse than that produced locally. AAK needed a lead time of 35 days for production, and the whole time was also in line with Martin's re-purchasing time schedule. After finalizing the whole order, Martin reported to the boss. The boss was very happy that AAK hydraulic sequence valve benchmarked the American quality, and also saved the purchasing cost. Martin told me that his boss asked him to send samples of previously purchased hydraulic valves to AAK for quotation. AAK hydraulic sequence valve keeps pace with American manufacturers. Not only the hydraulic sequence valve, our quality of hydraulic flow control valve also convinced a Germany customer. Welcome to have a try! https://www.aakindustry.com/info-detai , l/hydraulic-sequence-valve-aak126

Nantan, from Greece, is an old friend of mine. He has cooperated with AAK Hydraulic Valve for 5 years. Last month, I received a sample of hydraulic cartridge relief valve from him. He needed me to optimize it. In the first half of this year, their customer's die casting machine prototype needed to customize the hydraulic cartridge relief valve. Due to tight time frame, Nantan made samples from a local hydraulic cartridge valve manufacturer who had cooperated with them. The equipment commissioning was not smooth, and there was vibration and noise when the hydraulic cartridge relief valve was opened under the condition of large flow and pressure relief. The manufacturer advised that the problem was caused by the internal structure of the hydraulic cartridge relief valve, but he was unable to optimize it. Their engineers complained that the hydraulic cartridge relief valve purchased by Nantan was abnormal, which embarrassed Nantan. Nantan contacted other local hydraulic cartridge valve manufacturers, but they disagreed. Nantan realized that he could only ask for help overseas, so he sent me 3 original samples. According to their hydraulic system schematic diagram, on-site debugging video, AAK engineers suggested that not only the structure of the hydraulic cartridge relief valve should be optimized, but also its functions should be improved. After obtaining additional time, Nantan asked AAK to make samples for the hydraulic cartridge relief valve as soon as possible. After 35 days, AAK sent 10 hydraulic cartridge relief valve samples. A month later, Nantan informed AAK that the prototype had been successfully debugged and delivered to the customer. AAK optimized the structure of this hydraulic cartridge relief valve from 3 aspects, and perfected the hydraulic cartridge relief valve with pressure relief buffer function: 1. The side of the hydraulic cartridge relief valve cage is provided with a valve oil inlet and a valve oil outlet. The valve spool is installed in the axial hole of the valve cage, the control cover plate is at the upper end of the valve cover, and the poppet valve spool and regulating rod are set in the axial hole of the screw sleeve. 2. The upper end of the control cover plate is connected with the buffer valve body. The buffer valve spool is set in the axial hole of the buffer valve body. The control port is connected with the damping hole. The control port is connected with the control chamber through the hole in the middle of the buffer valve spool. 3. The axial hole of the electromagnetic valve body is provided with an electromagnetic valve spool, the working port is connected with the control port through the annular groove in the middle of the buffer valve body, and the oil drain port is connected with the oil return port through the buffer valve body and the control cover plate. The hydraulic cartridge relief valve with optimized structure has high control degree and reliability, small flow resistance, small impact, large flow capacity and fast action when the valve spool is opened in buffer mode, which can effectively reduce system vibration and noise, operate stably and have a long service life. AAK hydraulic cartridge relief valve, small impact, no vibration, you can also have a small try! https://www.aakindustry.com/info-detai , l/relief-valves-aak448

The customers who believe in you will pursue you to purchase your integrated hydraulic cartridge valves; while those who don't believe in you, even after consulting N+1 times, they won't come to you to buy an integrated hydraulic cartridge valve. I have also been requesting our sales department for integrated hydraulic cartridge valves, no value, no quotation; Without trust, it is difficult to make a deal.   At the end of work yesterday, a customer of integrated hydraulic cartridge valve in Turkey, a girl with a beautiful voice really moved me. She told me that she was a Chinese, her parents opened shops in Turkey and operated integrated hydraulic cartridge valves business. Now she is responsible for purchasing all the integrated hydraulic cartridge valves, and is the second generation of the enterprise. A few days ago, she left us a message on B2B, but did not receive a response from us. Then she searched for AAK integrated hydraulic cartridge valve on Google, and called AAK integrated hydraulic cartridge valves in China. I have to sigh that if an integrated hydraulic cartridge valve customer wants to get into contact with you, she will do her best to contact you. It's not a pity if a customer can not get into touch with AAK, either there's no fate or it's not AAK's target customer.   After 20 minutes of telephone communication, I learned that their hometown is Wenzhou and have operated integrated hydraulic cartridge valves in Turkey for many years. In there, users are still accustomed to purchasing and repairing the integrated hydraulic cartridge valves from physical stores, and they have a significant advantage in the local market. I also asked if they have their own warehouse, any agents, and the payment terms for the goods.   She is a very friendly Chinese, our 20 minute conversation was also very pleasant. Unlike some integrated hydraulic cartridge valve customers who were eager to ask for prices at the beginning, they didn't even thank you for the price. This way, they only asked for the price, without comparing the quality of the integrated hydraulic cartridge valves, and over 90% of them would not place an order in the end.   After hanging up the phone, I immediately emailed her and sent her a list of integrated hydraulic cartridge valve models that AAK has, as well as uploaded the e-catalog of AAK integrated hydraulic cartridge valves. Although we haven't met yet, I can feel that she is a very polite person and a detail oriented person. Therefore, I must communicate with her with Co frequency resonance. Spending time with such clients is worth it.   For customers of integrated hydraulic cartridge valves with physical stores, they usually need the service of small batches, multiple varieties, and fast cycle operations. AAK has served 11 physical store customers engaged in integrated hydraulic cartridge valve maintenance and after-sales service, not only does it involve standard parts, but there are also personalized integrated hydraulic cartridge valves, and even very niche integrated hydraulic cartridge valves. The China integrated hydraulic cartridge valve manufacturers that are able to do both design and manufacturing at the same time is less than 10% in Ningbo.   For the integrated hydraulic cartridge valves that other valve manufacturers in China cannot do well, try with AAK. Give me a try and return you a surprise.   AAK HYDRAULIC VALVES (611) 2023-06-23 https://www.aakindustry.com/info , -detail/cartridge-valve-manufacturers-aak611

On Monday afternoon, I received an email from Tony. Tony is a purchasing manager of CASAPPA in Italian, mainly responsible for the purchasing of hydraulic pump components, and the work has been very smooth. Last month, they received a complaint from the largest customer that the pressure at the outlet of the hydraulic pump sometimes rises by itself, resulting in unstable operation of the equipment. The customer's site engineer couldn't solve it and turned to CASAPPA for after-sales service. Although the warranty period has expired, they still need to help customer solve the problem. Their engineers tested various parameters of the hydraulic pump. After comprehensive analysis, they were still uncertain about the root cause, but they suspected that the hydraulic pressure relief valve in the pump is faulty. The engineer asked Tony to contact the original supplier of the hydraulic pressure relief valve and ask him to send a sample of the hydraulic pressure relief valve for replacement and test. It is a local hydraulic valve manufacturer and they still have samples in stock. After receiving samples and commissioning, the engineer's suspicion was proved to be correct. After replacing the hydraulic pressure relief valve, the hydraulic pump worked normally. Tony asked the original hydraulic valve manufacturer to urgently replenish 30 hydraulic pressure relief valves to solve this complaint. The manufacturer said that the shipment has passed the two-year warranty period. At present, there are only 3 samples in stock. The remaining quantity needs to wait in production schedule for production, and can only be delivered after 3 months. If offering this plan to the big customer, Tony would be scolded by the boss. He thought of AAK, because the hydraulic valve failed last year, which was also solved by AAK. Tony established a business relationship with us last October. Now we are also friends besides business. We often discuss the knowledge related to hydraulic valves. His email on Monday is just to ask for help on this hydraulic pressure relief valve. After knowing these conditions, I asked him to send us samples of those faulty hydraulic pressure relief valves, and provide us the drawings of this hydraulic pressure relief valve, noting those special requirements. After receiving and disassembling the samples from Tony, we found that the main valve spool of the hydraulic pressure relief valve was too loose and had increased leakage, then the pressure at the oil outlet increased. The problem should be caused by high-frequency wear or insufficient accuracy of the original shipped hydraulic pressure relief valve. The engineer of CASAPPA asked us to reply why it was determined that it was the problem of the valve spool? Because in the pressure reducing control circuit, after the directional valve works, the flow at the valve outlet becomes zero, but the pressure still maintains the originally set pressure. In this case, the flow through the pressure reducing port is only pilot flow. Due to the small pilot flow, which is generally within 2L / min, the pressure reducing port of the hydraulic pressure relief valve is basically close to the fully closed position and the opening is very small. According to the flow continuity theorem, this part of leakage must also flow from the damping hole of the main valve spool, that is, the flow through the damping hole is composed of pilot flow and leakage. The area of the damping hole and the oil pressure in the spring chamber of the main valve remain unchanged (the oil pressure in the spring chamber is determined by the pre compression shrinkage of the pressure regulating spring that has been adjusted). In order to increase the flow through the damping hole, the oil pressure in the lower chamber of the main valve will inevitably increase. Finally, it is determined that the main valve spool of the hydraulic pressure relief valve is too loose or the accuracy is not enough. The engineer was convinced by our whole demonstration and suggested Tony to take AAK as their main hydraulic valve supplier. AAK produced 30 hydraulic pressure relief valves in 15 days and guaranteed the quality for 3 years. Half a month later, Tony sent an email saying that everything was normal with the hydraulic pump after using AAK hydraulic pressure relief valve. The customer fed back his appreciation to his boss, who was particularly satisfied with his ability to deal with the crisis decisively and paid more and more attention to him. AAK has been doing what peers are unwilling to do. If you have any problem about hydraulic pressure relief valve, or about hydraulic pressure control valve, you can also contact us to have a small try. https://www.aakindustry.com/info-detai , l/hydraulic-relief-valve-aak125

AAK uses endoscope C50 to detect the internal burr of the hydraulic valve block, and then sprays the burr remaining in the hydraulic valve block with high-pressure solution, so that there is nowhere for the burr to hide. Nearly 95% of domestic hydraulic valve manufacturers are not equipped with endoscope and ignore 100% removal of the residual burr of the hydraulic valve block. The American customer who has suffered a loss elsewhere chose to order from AAK again. Most domestic hydraulic valve manufacturers use conventional physical methods to deal with the burr of hydraulic valve block, and check whether the burr is cleaned by experience, especially the burr of deep hole or magnetic burr, which can hardly be cleaned. It is common that the defective rate of hydraulic valve block exceeds the standard due to human error. At the beginning of last year, we received an inquiry for hydraulic valve block from Hunter, an American customer. We calculated the price according to his hydraulic valve block drawings. Hunter was not satisfied with our quotation. Because the communication was very pleasant, I wanted to make friends with hunter and gave up my commission to adjust the price. Hunter frankly said that although the new price of AAK hydraulic valve block meets his target price, the prices of other hydraulic valve manufacturers are still cheaper than those of AAK. We can only withdraw from the purchase of hydraulic valve block amicably. If something goes unusual, there will be problems. 2 months later, Hunter came back to us and said that he was very willing to accept our quotation for hydraulic valve block. He informed that there were different degrees of burrs at the internal cross holes of the hydraulic valve block samples proofed by the original hydraulic valve manufacturer. The hydraulic valve block samples were modified 3 times. Each time the cartridge valve was installed and debugged, the valve spool was stuck from time to time. The factory has also conducted commissioning for many times, and has been unable to remove burrs for 100%. He can only give up this hydraulic valve manufacturer and came back to AAK. Burr must be produced in the drilling process of hydraulic valve block, which is very harmful to the hydraulic system. In addition to adopting appropriate treatment process for burr removal, it is also necessary to have relevant auxiliary testing equipment to guarantee the complete 100% removal of burr. Hunter asked us to arrange approval samples of hydraulic valve block immediately. After 15 days, we sent the hydraulic valve block samples. On the 3rd day after Hunter received the samples, he sent an email to inform AAK that the samples passed testing at one time. Hunter admired that AAK can get the hydraulic valve block samples approved at one time that the peer can't get approval at 3 times. At the same time, he also expressed his curiosity about how AAK can accurately remove the burrs? Because this hydraulic valve block has many internal cross holes and deep holes. Firstly, the accurate position of burr in the hole must be found, and then the burr shall be removed by high-pressure solution jet. Then, AAK has one more process than peers, using endoscope C50 to recheck the subsequent residual burr. If there is still residual burr, it shall be cleaned and rechecked again until it is completely eliminated. This is the detail awareness lacked by other hydraulic valve manufacturers, and also the reason that AAK can achieve 100% deburring. Details make a difference. AAK concentrates on details, strives for perfection. You can purchase at ease, use at ease for all types of hydraulic valves produced by AAK. https://www.aakindustry.com/info-detail/hy , draulic-valve-block-aak124
