We know that when an object is illuminated by light, a reflection phenomenon occurs, and the reflected light in this phenomenon is expressed by an index that is gloss, and the size of the reflection i......
2019-12-02The matting mechanism of matting powder is: the gloss of the coating film is reduced by adding matting fillers, such as talc, ultrafine silica and other fillers; the coating film is glossy by adding t......
2019-12-02Both matting powder and matting agent can play a role in eliminating the gloss of the target material, but what is the difference between a "powder" and a "agent"? Matting powder is a kind of easy-......
2019-12-02To achieve the matting effect of the matting powder, it is necessary to cause diffuse reflection of light on the surface of the paint film, otherwise the matting effect is not good. Therefore, do not ......
2019-12-021. Matting powder treated with organic wax has small oil absorption, easy to settle and form soft sediment, and the matting agent treated with organic matter has a lower matting efficiency than the eq......
2019-12-02Matting agents are generally like small sponges with many pores inside. Higher porosity particles are lighter, so there are more particles per unit mass, precisely because these particles produce the ......
2019-12-021. The relationship between average particle size and transparency: As the average particle size increases, the transparency becomes worse. This is because transparency refers to the property t......
2019-12-02Hydrated silica has very good abrasion resistance and strength. As mentioned above, it is "white", so when it is used in paper, it can increase the whiteness and opacity of the paper and make the pape......
2019-11-29In addition to the large surface area, the adsorption capacity of hydrated silica is also very strong. Therefore, hydrated silica is one of the main types of toothpaste friction agents. Due to the sup......
2019-11-29Silica has a large surface area, a refractive index of 1.45-1.50, and a paint film containing a hydrated silica matting agent. When light is incident, diffuse reflection occurs, thereby forming a glos......
2019-11-29Silica is widely used as a reinforcing agent in the rubber field, and its amount accounts for 70% of the total. Especially when manufacturing white, colored and light-colored rubber products, whi......
2019-11-29The difference between precipitation method silica and gas phase method is mainly the particle size and purity. Precipitated silica is generally micron, and fumed silica is generally nanometer. Pre......
2019-11-29In agricultural chemicals, such as pesticides, high-efficiency spraying fertilizers, etc., use white carbon as a carrier or diluent, disintegrating agent, and disintegrating agent. Use in water-disper......
2019-11-29White carbon black is used in colored rubber products to replace carbon black for reinforcement, to meet the needs of white or translucent products. White carbon black also has strong adhesion, tear r......
2019-11-29Using silica as a paper filler can improve the paper's resistance to ink transmission and mechanical strength, increase whiteness, and reduce unit weight. Can effectively reduce paper weight, reduce p......
