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
