microsilica manufacturer, gansu xinyuan microsilica co., ltd., introduce you to microsilica and composition, physical properties of micro microsilica is also called the silicon ash or condensed silica fume, ferroalloy smelting ferrosilicon and industrial silicon, silicon metal, ore heat furnace to produce a large number of volatile strong sio2 and si gas, gas emission and air oxidation quickly after condensation precipitation.
it is a by-product of large-scale industrial smelting, and the whole process needs to be recycled with dusting environmental protection equipment, because the density is small and also needs to be encrypted with encryption equipment. in the process of producing microsilica, the manufacturer needs to go through three important processes and strict control:
first step: exhaust gas purification: the exhaust gas from the electric furnace goes through the smoke cover and main flue gas pipeline, and then enters the cyclone separation deduster after cooling through the cooler, and then goes through the bag deduster. the dust is collected by the inner surface of the filter bag. after purification, the smoke which reaches the environmental protection standard is discharged from the outside of the filter bag and rises to the top of the dust collector and is discharged into the atmosphere from the discharge port.
step 2: collect the microsilica: when the equipment running resistance or time reaches the set value, the unloading process starts. with the negative pressure in the front section of the main fan, the cleaning of silica fume in each compartment of the bag-type dust collector is realized through switching of the air suction pipe and air inlet and outlet valve.
step 3: silica powder encryption: the initial density of the microsilica collected by the bagging dust collector is only 150-200kg/m3, which costs a lot in transportation. therefore, the encrypted silica powder is a microsphere, and its bulk density increases from 0.2t/m3 to 0.3-0.6t /m3, which can reduce packaging and transportation costs by about 30-60%. at the same time, loading and unloading efficiency has been improved, storage space and occupation have been reduced, and dust emission on the production site has been greatly reduced, thus improving labor conditions and environment.
scope of application: commercial concrete, high-strength concrete, self-leveling concrete, amorphous refractory material, dry mix (pre-mix) mortar, high-strength non-shrinkage grouting material, wear-resistant industrial floor, repair mortar, polymer mortar, thermal insulation mortar, anti-seepage concrete, concrete compacting agent, concrete preservative, cement base polymer waterproof agent; rubber, plastics, unsaturated polyester, paints, coatings and other polymer materials, the modification of ceramics and so on.
