The use and properties of silica

Hits: 686 img

Silica has a wide range of uses, and different products have different uses. Used as a good reinforcing agent for synthetic rubber, its reinforcing performance is second only to carbon black, and even better than carbon black if it is ultra-fine and properly surface treated.

Silica is added to the resin to improve the moisture-proof and insulating properties of the resin. Filled in plastic products to increase slip resistance and oil resistance. Filled in silicone resin, it can be made into plastic resistant to above 200℃.

Silica can be used as a filler material in polyethylene, polypropylene, polybutene, epoxy resin and other plastics, which can improve the elastic strength and wear resistance of plastics, as well as the thermal stability of hardness. The use of silica in cables can also improve the electrical insulation of cables. For example, methyl vinyl silicone rubber high-voltage lines should use fumed silica or high-quality precipitated silica. It is often difficult to separate the two layers of plastic films, and it is difficult to open the mouth of the bag when bagging, so white carbon black is a very useful opening agent.

Due to the high calorific value of carbon black, foreign automobile tires used for highways also tend to add silica. At present, the requirements for bicycle tires in domestic and foreign markets are also increasingly diversified. For example, new fancy varieties such as tire bead colorization and flashing circles are produced with white carbon black instead of carbon black.

In the production of rubber shoes, people not only require fastness, but also beautiful color, comfortable and lightweight for rubber shoes, rain boots, sports shoes, travel shoes, fitness shoes, ballet shoes, etc. Silica not only has good reinforcement, wear resistance, slip resistance and upper adhesion, but also is a good light-colored reinforcing material. Therefore, it plays an important role in providing the quality and style of shoes in the development of rubber shoes. important role.

Due to a series of advantages of silica products, it can be widely used in many fields. Rubber products White carbon black is used in colored rubber products to replace carbon black for reinforcement to meet the needs of white or translucent products.

Silica also has super adhesion, tear resistance and heat resistance and anti-aging properties, so it can also replace part of carbon black in black rubber products to obtain high-quality rubber products, such as off-road tires, engineering tires, etc. . Transparent color and opaque toothpaste with silica as filler and abrasive, this kind of toothpaste has good flexibility and dispersibility, the paste is smooth, soft, and abrasive, and does not abrade the toothpaste tube; it can keep the medicated toothpaste Medicinal stability.

Silica is used in adhesives made of natural rubber or synthetic rubber to provide thixotropy and reinforcement. At the same time, due to its extensibility, it can also improve adhesion, and it is of high quality and low price. Silica is also used in products to improve free flow, such as lawn fertilizers, fungicides, laundry bleach, phenolic and urea plastics, making rubber sulphur and anti-caking compounds.
