what are the other uses of microsilica-pg电玩城

microsilica is commonly referred to as the micro powder in the industrial field. the microsilica is made by collecting and processing the smoke and dust from industrial waste gas in the industrial electric furnace at high temperature during the refining of industrial silicon and industrial ferrosilicon. its particles are very, very small, and the average particle size is almost several levels of nanometer, so people call it silica powder.

the microsilica is mainly used in combination with concrete, which is to determine the method of adding microsilica according to the design requirements of the drawing, namely the optimal amount of microsilica and the proportion of sand and stone. other additives are added in accordance with common concrete design methods. perhaps some people said, pure cement is not also good, the ground that pure cement laid is very high compressive strength also, why must join silica powder? because of the surface of the concrete with the silica powder, it is much more resistant to pressure than the surface of pure cement.

because the particles of the silica powder are very small, the silica powder also acts as a filling space in the concrete. to a large extent, the gap in hydration slurry is reduced, the distribution of gap size is improved, the strength of road surface is improved, and the permeability of road surface is reduced.

other uses of microsilica

rubber industry: after adding a certain amount of microsilica to the rubber, the extension shrinkage, tear resistance and aging resistance are greatly improved. this kind of rubber also has good dielectric property and low water absorption capacity.

as anti-caking agent: substitute for mica or diatomaceous earth as raw material to prevent agglomeration of fertilizer particles.

resin pelletizing adhesive: micromicrosilica has large surface area and strong adsorption.

aqua industry: can replace quartz mine, production module is 4.

pan was used as well cementing in the oilfield: jilin oilfield, liaohe oilfield, karamay oilfield, etc., all used a large amount of silica powder, and achieved good results.

it is applied in insulating materials, waterproof materials, paints, coatings, printing industry, etc.
