2019-06-25Silica is superior to other white fillers in reinforcing other rubbers, second only to carbon black. Compared silica filled vulcanizates, silica/rubber composites have the advantages of good insulatio......
2019-06-25In the production of rubber shoes, people not only require fastness, but also a beautiful color, comfortable and light, for rubber shoes, rain boots, sports shoes, travel shoes, fitness shoes, ballet ......
2019-06-25The use of silica is very versatile and different products have different uses. It is used as a good reinforcing agent for synthetic rubber. Its reinforcing performance is second only to carbon black.......
2019-06-25Silica has a very significant reinforcing effect on various rubbers, and the reinforcing effect on silicone rubber is particularly prominent. Silica is a white reinf......
2019-06-253. Mooney viscosity of rubber compound The ability of silica to form a gel is comparable to that of carbon black. Therefore, when the white carbon black is mixed, the Mooney viscosity of the rubber i......
2019-06-251. Mixing and dispersing of rubber compound Since silica has a large specific surface area, it tends to be secondary aggregated, and it is easy to absorb water in the air, so that......
2019-06-255, industry technical characteristics The precipitated silica is usually chemically reacted with sodium silicate and concentrated sulfuric acid to form precipitated silica, which is then washed with ......
2019-06-254, the technical level of the industry Since 2008, China's sedimentary silica industry has followed the three concepts of scientific development concept, brand-name product strategy and circular......
2019-06-25(2) Development history of Chinese fumed silica China's fumed silica production began in the 1960s, but for a long time only Shenyang Chemical Plant and Shanghai Chlor-Alkali Plant have produced tens......
2019-06-252. China's silica market (1) Development process of Chinese precipitation silica China's precipitation method silica industry started to develop slowly. In 1958, the first set of precipitation ......
2019-06-25Silica is a general term for finely powdered or ultrafine particulate anhydrous and hydrous silica or silicates. It is a white, non-toxic, amorphous fine powder or granule with a large SiO 2 content......
2019-06-25The silica is roughly classified into a precipitated silica and fumed silica according to a production method. Fumed silica and precipitated silica are essentially indistinguishable, and the chemic......
