What are the precautions for selecting heat conducting gasket?

Thermally conductive silicone film is also called thermally conductive silicone pad. Thermally conductive silicone film has good thermal conductivity and high-level pressure resistance. It is a thermally conductive composite material with great manufacturability and practicability in China. Silicon is the old name of silicon. In mainland China, silicone glue can generally be called silica gel. Thermally conductive silicone film is one of the types of silica gel products, In Taiwan and some other Asian countries and regions, the thermal conductive silica gel sheet is still called thermal conductive silica film. The thermal conductive silica gel gasket has a wide range of application technologies, mainly including in-vivo research of enterprise electronic control appliances and automobile engineering machinery. As a component affecting heat dissipation and insulation, it can be developed and used for a long time without corrosion to metal components, So what are the safety precautions we need to pay attention to when using? When purchasing thermal conductive silica gel foot mats suitable for students' own enterprise products, the heat source, insulating thermal conductive silica gel sheet and radiator top cover should be kept in full contact, and there should be no gap in the middle, because they mainly conduct heat by contact with each other. If there is a gap in the middle, it will greatly increase the social contact thermal resistance, So as to reduce the thermal conductivity. In the long-term development work, the temperature should be kept between - 50 and 200 ℃. Due to the easy adhesion of silica dust, the process should keep clean and flat thermal insulation and heat conduction siloxane sheet, three and radiator cap, which can avoid the influence of dust and dirty substances on thermal conductivity and viscosity. The products are widely used in IGBT, power module, MOS tube heat dissipation, CPU, radiator, heat conduction source and other fields. According to their own performance requirements, select thermal conductivity, insulation suitable for their own silicone foot pad, with double-sided adhesive backing self-adhesive characteristics, etc. Although the silica gel has good anti vibration and anti compression performance, it should be handled with care and uniform pressure during transportation to avoid damage to the thermal insulation and heat conduction silica gel gasket, so as to give better play to the role of thermal insulation and heat conduction silica gel. Silicone pad itself has good EMC protection due to its thermal conductivity material with thermal insulation characteristics. It is not easy to pierce, tear or damage. Silicone material is in compression state. It is a good EMC reliability. Heat conductive silicone grease is easy to dry on the surface during curing at room temperature, unstable at high temperature, easy to volatilize and flow, The heat capacity will gradually decrease, which is not conducive to long-term reliable system operation.

What is the difference between silicone and rubber

Now silica gel and rubber products are widely used in our life. Different ingredients make different products. Today we'll learn about the differences between them. Firstly, silica gel is a highly active adsorption material, the main component is silica, while rubber is a highly elastic polymer material, the main component is latex, which is produced in rubber trees; Secondly, it has different characteristics. Silica gel has good adsorption and can adsorb a variety of substances, while rubber has high elasticity, can change different shapes, and has high tensile strength and elongation; In addition, silica gel is chemically stable, insoluble in water, non combustible and high heat resistance, while rubber is flammable and easy to soften and melt in high temperature environment. Characteristics and application of silica gel Silica gel is an amorphous substance with stable chemical properties, non-toxic and harmless, no allergic reaction, insoluble in water and any solvent, and contact with other tissues will not change its original elasticity and softness. It is not easy to melt in high temperature environment, which lays a foundation for future use. For example, silicone is used for prosthesis in nose augmentation surgery, which is not easy to deform. Silicone is also used in breast augmentation surgery, which is not easy to change its softness. In general, the biggest advantage of silica gel is good adsorption, good heat resistance and insulation. It is precisely because of these characteristics that silica gel is used as desiccant and adsorbent. It has high heat resistance and no performance change in high temperature environment. Therefore, it is used as the sealing ring of electrical appliances. It is also non-toxic and tasteless when heated. Characteristics and application of rubber The composition of natural rubber mainly comes from the latex produced by rubber tree. After processing, it is made into synthetic rubber. The biggest feature of rubber is plasticity and high elasticity. It can change the state of objects at room temperature. Because of its high elasticity, it also has the function of cushioning and shock absorption. This can be used to prevent noise and reduce vibration. It is generally used to make shock absorbers, mobile phone supports and so on. Rubber is mainly used in, for example, the rain shoes, warm water bags, elastic belts, etc. in our life are made of rubber, and the automobile tires we can see everywhere are made of rubber. Because rubber has plasticity and good elasticity, it can recover quickly after tire deformation, and has wear resistance, which can also reduce the vibration during operation. Rubber is very useful in our life, In addition, the recent hot latex pillow mattresses are all due to natural rubber. Latex mattresses do not collapse like ordinary mattresses, but also due to high elasticity. In short, rubber and silica gel are all over our lives

What is the difference between silicone gasket and rubber gasket?

What is the difference between silicone gasket and rubber gasket? In the use of silica gel sealing gasket, our application environment is different, so for some occasions, our application of silica gel and rubber is also different, and the use effect and characteristics are also different. Silica gel products are also one of the types of rubber products. The difference between silica gel and rubber lies in the use of toxic and non-toxic. When burning silica gel, there will be no open fire. When it burns, the smoke is white, and when burning rubber, it emits black smoke, pungent and black, which has a very strong taste. Today's silicone products manufacturers use non-toxic and environment-friendly synthetic rubber and natural rubber as raw materials. Synthetic rubber includes chloroprene rubber, CIS polybutadiene rubber, styrene butadiene rubber, etc. The structure of natural rubber is high polymer. When rubber is deformed by tortuous extrusion under external force, it can recover quickly and has good chemical stability and mechanical properties. It has good softness and can be used in some high and low temperature resistant occasions. However, rubber products are not as good as silica gel products for low temperature applications. Now we choose to use silica gel products instead of rubber products in many aspects. Rubber products are now commonly used in our industrial manufacturing, auto parts and Agro industrial manufacturing. In the production process, because the elastic cohesion of rubber cannot be dissipated, the product has unstable hardness shrinkage, and the cohesion can be stabilized after a period of buffer. Therefore, care should be taken in the coordination and calculation of molds during production, otherwise bad conditions are easy to occur, Compared with silica gel, the performance of rubber is often not as comprehensive as that of silica gel products. Silica gel is used at home and in restaurants, which is very in line with the needs of many friends. For many friends, rubber is odorous and toxic substances and is rarely used in life. Therefore, rubber products are basically used in some industrial manufacturing, Due to the high price of silica gel compared with rubber, rubber is still selected for the same performance.
