White Powder 99% Purity Nonionic Polyacrylamide 20-40 Mesh
Description of nonionic polyacrylamide: Technical specification of nonionic polyacrylamide CAS no: 9003-05-8 appearance: white powder powder size: 20-40mesh Molecular weight: 8~16 million drgree of hydrolysis: 5-9% solid content: ≥88-90% insoluble matter: ≤0.02% Dissolution time: ≤60 minutes Mixture concentration: 0.1%—0.5% storage: 2 years Residual unit: ≤0.1% product usage: industrial use only Advantages of non-ionic polyacrylamide mainly used as a flocculant. Because its molecular chain contains a certain amount of polar genes which can adsorb suspended solid particles in water, the particles are interbridged to form large flocculates. Non-ionic polyacrylamide can accelerate the settlement of the particles in the suspension, has a very obvious speed up the clarification of the solution, promote filtration and other effects, widely used in the chemical industry wastewater, waste liquid treatment, municipal sewage treatment. Especially when the sewage is acidic, the use of this product is most suitable. Can be used with inorganic flocculants such as polyiron, polyaluminum and other inorganic salts. Package: Inner package : Plastic PE film; Outer package: kraft bag , N.W 25 kg/bag Storage: Stored in a dry cool and ventilate place, it will keep good for 6 months. Advantage: 1. Lower dosage 2. Easily soluble in the water, dissolves rapidly 3. Non corrosive 4. Reduction in sludge of dewatering process Technical index: ITEM NO.

Textile auxiliaries; Adding some other chemicals can be prepared into chemical sizing, used for textile sizing, can improve the adhesion, permeability and desizing performance, so that the fabric has spinning electrostatic properties, reduce sizing rate, reduce skein spots, cloth breaking rate and falling matter. 3. Sewage treatment; When the sewage system is acidic, the selection of non-ionic series of polyacrylamide is more appropriate, and inorganic flocculant polyaluminum, aluminum sulfate and other use in conjunction, in the water treatment effect is better. 4. Metallurgical beneficiation; For example, in the flotation and smelting of zinc, manganese and copper, the leaching liquid and residue can be entered into PAM to improve the sharing efficiency. 5, sand prevention and sand fixation; The non-ionic polyacrylamide dissolved into 0.3% concentration to add crosslinking agent, spraying on the desert can prevent and fix sand. 6, chemical grouting agent; 9.5 parts of non-ionic polyacrylamide and 0.5 parts of NN-- methylene diacrylamide miscibility can be used as a chemical grouting agent for water plugging of DAMS, foundations, tunnels and so on. 7, soil moisture agent; It holds water and holds sand in the soil. Hill planting grass, tree planting, sand and dust can play a role in moisturizing agent. White Powder 99% Purity Nonionic Polyacrylamide 20-40 Mesh 0 Contact:

Cellulose Ether Hpmc Powder Hypromellose Cas Number 9004 65 3
HPMC Cellulose Ether Hpmc Hpmc Chemical Formula Of Cellulose CAS 9004-65-3 In the wet mortar, the water in the mortar evaporates and the cellulose ether concentrates on the surface, forming a film on the surface of the mortar within 5 minutes, reducing the subsequent evaporation rate. As more water flows from the thicker migration part to the thinner part of the mortar, the formed part of the film begins to partially dissolve, and the migration of water will cause more cellulose ether to accumulate on the surface of the mortar. The formation of cellulose ether on the surface of the mortar has a great influence on the performance of the mortar: The first formed film is too thin, it will dissolve twice, can not limit the evaporation of water, and reduce the strength. item value Classification Chemical Auxiliary Agent CAS No. 9004-65-3 Other Names Methyl Cellulose MF CH2CHOHCH3 Purity 45000-5000 CPS Place of Origin China Type Adsorbent Usage Coating Auxiliary Agents Brand Name MILAI Model Number FMC50000 Product name HPMC Appearance White Powder CAS Number 9004-65-3 Certification ISO9001:2015 PH 5-9 Viscosity 45000-50000cps particle size 80-120 Meshes Grade Industrial grade Moisture 5.0 % max.

PU wheel
Established in 1990. Our Group is located in the Qingdao China, specializing in design and producing different kinds of Polyurethane wheels, Our Polyurethane wheel are widely used in shopping trolley,furniture,medical instruments,handcart, industrial apparatus,industrial trolley and rack, wheelbarrow, lawn cart, hand trolley, mobility chairs, home use, health care, Wheelchair,tool carts,baby troller etc. All wheels can be manufactured in different colors,sizes and various thickness accordling to per customer's design and specification . How to choose suitable PU wheels for your local market? It is different for per consumer’s requirement. We are facing the times which time is money and safety is the first thing, which is a great era for someone who are seeking value of products. In this case, we developed several series of high performance for polyurethane wheels to meet customer’s will. Customers fromAmericaand Europe need that performance of products is higher and higher. They pay more attention to excellent features than polyurethane wheel price. In order to meet consumer’s requirement, we invested huge capitals to develop several series for PU wheels. All raw materials must be top grade. Our cost is two times as expensive as cheap raw materials price. Our technical team tested thousands of times for PU wheel with outstanding performance. At last, we succeed in high characteristics of polyurethane wheel industry. I kindly ask for you to spend a little time to read following. 1)Wear proof type Life of the PU wheel is very long, which is over one time longer than common one. 2)Loading duty heavy type The polyurethane wheels can load more quantity than normal wheels, so consumer can save some work time. Consumer only uses the wheel under some special condition. 3)Anti-cracking type Consumer can use the PU wheel under cold weather. 4)Eco-friendly type Raw materials of the polyurethane tire don’t contain any harmful component to keep air clean. 5)Comfortable type The polyurethane wheel can reduce fatigue when consumer uses it. Why do someone quote low price for PU foam wheels? You can get 100 different price of polyurethane wheels if you inquiry 100 suppliers. Someone can quote very low price, and someone quote high price. Importers will be confused. How should I choose? You must understand the point which raw materials of PU wheel is expensive. Some companies add calcium powder to raw materials to cut down production cost. They add weight of calcium powder according to quotation. In fact, buyer give any price, polyurethane wheel manufacturer can supply, but PU foam wheel quality is different. Raw materials of PU wheels have A grade,B grade,C grade. Those very cheap PU wheel only use C grade and mix to calcium powder. Do you know calcium powder price is very cheap? We produce only use A grade raw materials and special formula for high performance. Our company invested huge money for research of high performance PU wheel. Do you know the standard of good PU wheel? One of my customers said that rough surface is good. What do you think of the point? I think that most consumers don’t understand what is good for polyurethane wheel. As an expert of PU wheel, I would like to share some ideas. Good PU foam wheel must bear features as followings: 1) smooth surface without small holes. 2) It can recover original shape under loading heavy weight. 3) Don’t crack under cold weather. 4) Long life under normal condition If someone add some cheap materials to raw materials of PU wheel, they have no above characteristics. Do you dare to buy cheap PU foam wheel? Do you know the best temperature for making PU wheels? Polyurethane wheels which produce in Spring and Autumn are excellent PU wheel’s surface is smooth and pretty. It’s reasonable temperature’s range from 5 degree Celsius to 20 degree Celsius. Why do PU wheels that produce in Summer and Winter is poor surface? It contain more water in air in Summer, in same time, raw materials of polyurethane wheel also hold more water. In very cold winter, foam temperature is too low, so foam effect is also poor. I advise that customers place PU wheel order in Spring and Autumn. If you have also other ideas, don’t hesitate to send me e-mail, then I require our technical team research and develop them to meet your personal requirement. It is our goal that per customer who is different and high requirement is satisfied with our products and service. Welcome to visit us: www.pufoamwheel.com Contact:
