5、Application in plastics
Silica is also often used in new plastics, adding a small amount of silica in the plastic mixing, will produce a significant reinforcing effect, improve the hardness and mechanical properties of the material, so as to improve the processing technology and product performance. In addition, silica has a small particle size, high transmittance and other characteristics, can make the plastic become more dense, increase the transparency of the plastic.
6、Application in ceramics
With gas phase silica instead of nanometer Al2O3 added to 95 porcelain, both can play the role of nanoparticles, at the same time it is the second phase of the particles, not only to improve the strength and toughness of the ceramic material, but also to improve the material's hardness and elasticity modulus and other properties, the effect is more desirable than the addition of Al2O3. The use of gas-phase silica to compound ceramic substrates not only improves the densification, toughness and finish of the substrate, and the sintering temperature is reduced significantly. In addition, gas phase silica in ceramic filters, corundum balls and other ceramic products in the application of the effect is also very significant.
7、Application in the paper industry
In the paper industry, fumed silica products can be used as a paper gluing agent, can improve the whiteness and opacity of paper, can improve oil resistance, abrasion resistance, feel, printability, gloss. And it can also be used for solarization paper, which can make the paper surface quality, ink stability, no cracks on the back, and it can be used in azide paper to produce excellent blueprint paper, and it can be used in coated paper instead of titanium dioxide. Add 1-2% fumed silica products, can reduce the weight of the paper, and paper thin, can improve the strength, prevent ink penetration, but also to make the printed text clear, increase opacity.
8、Application in toothpaste
Precipitated silica is currently the main varieties of toothpaste with friction agent. Precipitated silica has a large total specific surface area, strong adsorption capacity, adsorption of substances are also more uniform particles, which is conducive to improving transparency, because of its stable nature, non-toxic and harmless, is a better raw material for toothpaste. The refractive index of silica is 1.45 to 1.50, which is very close to the refractive index of other ingredients in toothpaste, so when mixed together, it plays the role of transparency agent. This property is used to make transparent toothpaste, a feature not found in any other rubbing agent.
9、Application in cosmetics
The excellent properties of silica such as non-toxic, odorless and easy coloring make it widely used in the cosmetic industry. Silica used in skin care products and cosmetics, so that the skin produces a smooth and soft feeling (“ball bearing effect”), resulting in a “soft focus effect”, which makes the light irradiated on the surface of the skin is evenly distributed, so that it is not easy to detect the wrinkles and blemishes of the skin. blemishes on the skin. In addition, the thixotropic property of silica prevents pigments from settling and can be used in products such as lipstick and nail polish.
