The results with the gas phase were compared in Table 1 to Table 5.4 on the above results and discussion can be seen practicing, wet ultra-fine silica powder has entered the industrial production stage, the product index close to the gas phase index of silica fine powder, and some were better than liquid gas l8 fine silica powder form of industrialization and product characterization of the ingredient list l Table 2 of rubber vulcanized rubber hardness measurement data time.

NMPa230503623052425638s. 68252252584932 interference 02627 {471O26681t372667 \O252.3262444.429O280 law. Rubber products used in the preparation from the point of view, rubber hardness index finished slightly lower than gas with it. Several key indicators are better than the rest of fumed. L5 minutes of curing conditions in which the tensile strength than the gas phase increased 1.54 times, 1.64 times increased elongation at break, wear gas law was only 4 / 5. In addition. I Z. 52966Z4602488859490652.481067l7.1585535256ll97l535 are also the preparation of rubber for high voltage insulators. All indicators are in line with national standards. Proved, wet process silica fine powder is fully applicable to the rubber industry. As raw materials cheap, small investment in equipment. Wet storm and lower product costs, only gas phase products, 3 / 10, its price can be significantly reduced. Silica is expected to further expand the application field of ultra-fine powder; wet production process and because there is no high-temperature roasting process, so the surface without sintering, the reaction activity, and is conducive to further surface modification and subsequent product development. Therefore, wet industrial production of fine powder of silica has broad market prospects. If further expansion of production scale and develop follow-up project. Will undoubtedly achieve greater economic efficiency, while China's economic development also has a larger role in promoting.
