　　In the world of industrial machinery, the performance of components is often dictated by their operating conditions. One such component, the NBR (Nitrile Butadiene Rubber) oil seal, is no exception. This article will delve into the working temperature range of NBR rubber oil seals and why it matters. 　　NBR rubber oil seals are widely used due to their excellent resistance to petroleum-based oils and fuels, silicone greases, hydraulic fluids, water, and alcohols. The NBR material is known for its strong wear resistance, good elastic properties, and low compression set. 　　However, like all materials, NBR has a specific working temperature range. The working temperature range of an NBR oil seal typically spans from -40°C to 125°C. This range is a general guideline and can vary based on the specific formulation of the NBR material. 　　Why does this matter? The working temperature range is crucial as it dictates the environments in which the NBR oil seal can function optimally. If the seal is subjected to temperatures below the lower limit, it may become too rigid and lose its sealing ability. Conversely, if the temperatures exceed the upper limit, the seal may become too soft, leading to deformation and potential failure. 　　Therefore, when designing or maintaining a system that uses NBR oil seals, it’s essential to consider the operating temperature. If the system is expected to function outside the NBR’s working temperature range, alternative materials like FKM (Fluoroelastomer) or Silicone might be a better choice. 　　Understanding the working temperature range of NBR oil seals is crucial for their optimal performance and longevity. By considering this factor, engineers and maintenance personnel can ensure the reliability and efficiency of their equipment.

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.

　　Oil seals are vital components in many mechanical systems. They prevent the leakage of lubricants from gaps within machines and bearings. But do these seals themselves need lubrication? This article will explore this question in detail. 　　The Role of Lubrication 　　Lubrication plays a crucial role in the performance and longevity of oil seals. It reduces friction between the seal and the shaft, preventing wear and tear. It also helps the seal maintain its elasticity, which is essential for effective sealing. 　　When to Lubricate 　　While oil seals are in contact with lubricants due to their function, additional lubrication during installation is often recommended. Applying a thin layer of lubricant on the seal and the shaft can make the installation process easier and prevent damage to the seal. 　　Choosing the Right Lubricant 　　The choice of lubricant is also important. It should be compatible with the material of the seal and the lubricant used in the machine or bearing. Incompatible lubricants can cause the seal to degrade or fail prematurely. 　　Regular Maintenance 　　Regular maintenance is key to the longevity of oil seals. This includes checking the condition of the seal and the lubricant regularly and re- lubricating or replacing the seal as needed. 　　While oil seals are in constant contact with lubricants, they do benefit from additional lubrication, especially during installation. Choosing the right lubricant and regular maintenance can significantly extend the life of the seal.

　　Oil seals are critical components in many mechanical systems. They prevent the leakage of lubricants from gaps within machines and bearings. Two common types of oil seals are SC and TC seals. This article will explore the differences between these two types of seals. 　　SC Oil Seals 　　SC oil seals also known as Single Lip Oil Seals, are typically used in applications where there is no pressure or very low pressure. They have a single lip that seals radially and axially against the shaft. The lip is usually manufactured from an elastomer material, which provides excellent sealing properties. SC oil seals are commonly used in electric motors, gearboxes, and pumps. 　　TC Oil Seals 　　TC oil seals also known as Double Lip Oil Seals, have two sealing lips. The primary lip prevents the leakage of lubricants, while the secondary lip keeps dirt and other contaminants out of the system. This makes TC oil seals ideal for applications where contamination is a concern. They are often used in automotive applications, such as wheel bearings and transmissions. 　　Key Differences 　　The key difference between SC and TC oil seals lies in their structure and application. SC oil seals have a single lip and are used in low-pressure applications. On the other hand, TC oil seals have a double lip and are used in applications where contamination prevention is crucial. 　　Both SC and TC oil seals play vital roles in various applications. Understanding their differences can help you choose the right seal for your specific needs.
