What factors can lead to unqualified silica gel products?

Factors affecting the quality of silica gel products are:

Some silicone products manufacturers use silicon products without incoming material inspection or use unqualified color glue in the production process, which will lead to unqualified product health inspection.

In addition, the production process does not need to be standardized. Food grade silica gel products have very strict requirements on the production process and product quality.

In order to complete the product as soon as possible, some manufacturers ignore the quality of the product, so that the product after production does not have enough time for processing. Substances break down, which can also cause the product to fail the test.

Another problem is the secondary vulcanization of silica gel products is not in place. For example, when silica gel is vulcanized with peroxide, the decomposition of the peroxide will trigger the material reaction, and then the low molecular compound will be stored in the silica gel, which will affect the performance of the silica gel products.

Finally, there are functional defects. Many silicone seals and silicone trim fittings require very important construction and hardness to support their function. Improper sealing and assembly of products result in poor appearance and function. This factor requires the manufacturer of silica gel products to cooperate with the proofing in the initial stage combined with the actual function of the product, and the mold production can only be carried out after the hardness and structure evaluation is qualified.

The difference between inferior silicone products and high quality silicone products:

High quality silica gel products have a strong service life and adaptability. Under non-artificial conditions, such as high and low temperature and unstable conditions, such as low temperature 200 degrees or oil pressure, ozone can also be used for a long time, in order to maintain good service life and use time, no deformation, use tension is insufficient. Inferior silica gel products can also be used, but the difference between inferior products is the difference between raw materials and curing agents. Therefore, it is possible to judge the difference between good and bad products in the same environment. Now many industrial electronic parts are replaced by silicone rubber products. Many manufacturers of silica gel products use inferior raw materials for mass production, but have achieved certain results.

Whether the actual life of silicone products is qualified, many products on the market have received consumer feedback. The service life of the product is too short, prolong. If the strength is too low, the product will be sticky. However, these materials are made of silica gel raw materials. In order to ensure the surface smoothness of products and control the viscosity of silicone oil, the addition of too much silicone oil destroys the composition of silicon atoms, leading to insufficient extraction of products and shortened service life, which makes many products become inferior products with reduced performance.
