The main component of silica gel is silica, which is chemically stable and non-toxic.
Silica gel has a strong adsorption capacity and can cause dryness on human skin. If the silicone enters the eye, rinse with plenty of water and seek medical attention as soon as possible.
Blue silica gel is toxic due to the small amount of cobalt chloride. Avoid contact with food and inhalation. If a poisoning event occurs, seek medical attention immediately.
3 characteristics of rubber products:
1. The rubber product is a raw material made from rubber raw materials and mixed with rubber. The rubber compound is used as a raw material in the rubber mixing process according to the characteristics of the rubber product required, and the required hardness of the product is determined. The product is molded and molded by a rubber flat vulcanizing machine. After the product is formed, it is finally subjected to flash processing to smooth the surface of the product without burrs.
2. Rubber is a hot-melt thermosetting elastomer, and plastic is hot-melt and cold-set. Because of the different types of sulfides, the temperature range of the curing of rubber is also quite different, even due to climate change, indoor temperature and humidity. Therefore, the production conditions of rubber products must be adjusted at any time. If not, the quality of the products may be different.
3. When the rubber product is molded, it is not able to eliminate the cohesive force prepared by the elastic body after being pressed by a large pressure. When forming the mold, it tends to produce extremely unstable shrinkage (the shrinkage rate of the rubber varies depending on the rubber type). ), it takes a while to be gentle and stable. Therefore, when a rubber product is designed at the beginning, regardless of the formula or mold, it is necessary to carefully calculate the fit. If not, it is easy to cause the product size to be unstable, resulting in low product quality.
