Liquid silica fine powder of industrialization and product characterization


Products, we test the method through some of its properties were characterized. 2.1 electron microscopy electron microscopy products,[link widoczny dla zalogowanych], the products shown in Figure 2 the results of the average size of less than 3Ohm. Cylindrical spherical particles. . Shi Shu Lei circle one trend in Figure 2 black fine hoe up soil around plants} spontaneous electrical shock in the key image was 2.2 IR spectrum of the infrared spectra of product spectrum shown in Figure 3. Can be concluded from the pattern analysis: product has hydroxyl groups, but there is no carboxyl,[link widoczny dla zalogowanych], carbonyl and ether ketone and other organic groups. 2.3x Figure 3 for a ray diffraction fine white hair and black 1;} and store the product IR x-ray diffraction patterns of a as shown in Figure 4 can be concluded from the map analysis: The product is a non-shaped crystals. 28 / r''Figure 4,[link widoczny dla zalogowanych], the black becoming white powder x-shake a shot past the domain Ya I shot around the specific surface area of 2.4 Composite Index Test: 2,[link widoczny dla zalogowanych],19 �� 10m. / KgpH value: 6.5 bulk density of 74kg / m ammonium: 0.05 mechanical impurities: 4 / 2g Loss on drying: <23 application performance: wet ultra-fine powder of silica as a reinforcing agent in butadiene rubber, rubber with a hardness of 77A Lx a determination but, rubber tensile testing machine, machine wear rubber key performance indicators measured. 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.

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.
