The importance of silica to rubber

Silk Black, the first reaction when hearing this name is that a large number of people think like Kain, it is just a kind of color. In fact, this idea is wrong. It is not a color, but a chemical, or even the all-purpose glue among chemicals. Why is it called the all-purpose glue among chemicals?
Silica is not black, on the contrary it is a white powdery substance. The main ingredients are relatively common in chemistry: mainly the silica material we learned in chemistry before. There are also some aluminum silicate and calcium silicate. Because of the properties of the manufacturing material, the entire silica has very good high temperature resistance and electrical insulation.

In addition, you don’t have to worry about odor at all because this product has no smell. Why do we call it the universal glue among chemicals? Let’s take a look at its uses. As an environmentally friendly and excellent-performance additive, silica is mainly used in the fields of rubber products (including high-temperature vulcanized silicone rubber), textiles, papermaking, pesticides, and food additives. It has uses in other areas as well. Electronic products, resin materials, plastic bags, coating pigments, and even my country’s overworked ceramics are all used. ​
For information about silica, we can learn that silica is widely used in various aspects and plays different roles in different aspects of various industries. Today we will learn about its important role in the rubber industry.
Precipitated silica It is used in rubber products including inner and outer tires of automobiles, dump trucks, trucks, tractors, forklifts, bicycles, etc., industrial belts, hoses, liners, rubber sheets, and threshing for grain processing. Silica is used to a greater or lesser extent in various rubber industrial products such as rubber rollers and rubber shoes. Adding a certain amount of silica to ordinary tires can increase the service life of the tire. Research and test results show that if 10 to 20 parts of silica can be added, the bonding and tear resistance can be improved, and the mileage of the tire can be increased. It can also enhance the tire’s grip on the road to facilitate safe driving. The mileage of tires in my country is lower than the international level, and one of the reasons is not using silica.
In addition, due to the high calorific value of carbon black, foreign automobile tires used on highways also tend to add silica. In short, the application trend of silica is becoming more and more extensive, making its prospects bright.
