what are the characteristics of lixinyuan microsilica powder?-pg电玩城

    microsilica is an excellent material with broad application prospects in high-tech fields at home and abroad, and can be widely used in chemical, metallurgical and other industries. used in cement or concrete to improve the performance of cement or concrete, and to prepare special concrete or composite cement with super high, high strength, wear resistance, erosion resistance, corrosion resistance, penetration resistance, frost resistance and early strength to adapt to oil field solids. special requirements for wells, offshore oilfield drilling platforms, seaport terminals, railway bridge highways, airport runways, tunnels and urban high-rise buildings; used in rubber to improve the ductility, tear resistance and tensile strength of rubber; used in refractory materials and ceramic products to effectively improve the strength and durability of the product.

    the chemical composition of micro-silica powder is silica (sio2), which is an inert substance. it does not react with most acids and alkalis. the microsilica is evenly distributed and covers the surface of the object. it has strong corrosion resistance and is resistant to air. the erosion capacity is increased by 3-16 times.

    high-quality microsilica has a low bulk density: one between 0.2 and 0.8 and one between 1.0 and 2.2. as a polymer filling material, it has less load than other mineral fillers, and has a small loading weight and saves polymer dosage, thereby reducing product cost.

    microsilica frost resistance: microsilica undergoes 300-500 rapid freeze-dissolution cycles, the relative elastic modulus is 10-20% lower, while ordinary concrete passes 25-50 cycles, and the relative elastic modulus is low 30. - 73%. therefore, the frost resistance of concrete can be improved.

    microsilica early strength: microsilica concrete shortens the induction period and has early strength characteristics. these features are very good!

    in the water conservancy, highway and bridge engineering projects, the micro-silica powder not only needs the above basic indicators, but also has very strict requirements for its wear resistance and erosion resistance. it is necessary to incorporate micro-silica powder.

    microsilica is widely used in argon-ventilated bricks at the bottom of ladle. jr-dy series ladle argon-ventilated bricks are made of high-purity and dense raw materials. after being identified by experts, its performance and technical level are leading in china. the argon-ventilated brick at the bottom of the ladle has the characteristics of high blowing rate, adjustable air flow, erosion resistance, erosion resistance, long service life and high safety. conducive to the purification of molten steel composition and uniform temperature.
