The production and processing of silica gel products seems simple, but for the poor production of products, some rework methods still need skills and experience. For example, the treatment of defective products, the grinding treatment of silica gel products has become a problem for many customers, especially for the appearance parts, which you may not want to buy as consumers, Defects can be seen at a glance, so for processing skills.

Appearance parts mainly refer to some decorations, silicone bracelets, clothing accessories and other materials, and this kind of products mainly need the appearance control of silicone product manufacturers, such as different hardness and softness, appearance black spots and impurities, surface blistering and so on. It is impossible to say that there is no quality at all, but it can be controlled within a certain range, which is the distinction between good products and bad products, However, specific requirements also need to be defined according to customer requirements.

When it comes to food grade, it is generally divided into export quality or contact with life. In addition to the above requirements for appearance, it also needs strict materials. Whether it can achieve complete tasteless, high transparency and no response to skin contact. Any testing and certification of materials can be passed to meet the requirements of materials.

In terms of characteristics, silica gel products are non-toxic, tasteless and colorless products with good texture and no harm to human body. Generally, fake silica gel products are difficult to achieve these effects. Fake and shoddy silica gel products are generally toxic and pungent! We can also distinguish true and false silica gel by flame combustion. Fake silica gel products produce black smoke and the residue is black powder when burning. Real silica gel products produce white smoke and the residue is white powder when burning no matter what color it is.
