$Heavy Desity Refractory Silica Bricks Sio2 95%$

Q: Physical solid waste disposal: The production of silicon material is added to the cause of waste brick:Preparation of silica brick pug, a certain amount of waste silica brick used to add ingredients, for the purpose of expansion and stress reduction products during firing

Q: The introduction of silica brick: Brick refers to the content of more than 93% products SiO2. Brick with SiO2 content of not less than 96% of silica as raw materials, adding mineralizer and binder, through mixing, molding, drying, sintering and other processes in the system. The higher the content of SiO2 in silica raw material, the higher the refractoriness of the product. According to the use of brick varieties, divided into: coke oven silica brick, brick for hot blast stove, electric stove with brick, brick for glass furnaces. According to the transformation is divided into: standard bricks, tiles, bricks and general special brick etc..

Q: What is acid refractory?: Acid refractory material usually refers to refractories with SiO2 content greater than 93%. Its main characteristic is that it can resist acid slag corrosion at high temperature, but it is easy to react with alkaline slag.

Q: What is the main material of silica brickIt's common, the kind we see so often!: An acid refractory consisting mainly of quartz and square quartz and a small amount of residual quartz and glass.

Q: Glass kiln brick for physical and chemical indicators?: Glass kiln with high quality silica brick products according to the standard JC/T615-1996, the single brick is divided into 3 grades: XBG-96, ZBG-96, DBG-96.

Q: The high thermal conductivity of silica brick and traditional brick what is the difference?: Tridymite content high thermal conductivity silica brick is 70%, tridymite content of traditional brick is 60%, tridymite content high thermal conductivity of silica brick than tridymite high content of 10% traditional brick,

Q: Can not use it two brick: Acidic silica brick refractory material, has good ability in acid slag erosion

Q: How to improve the thermal conductivity of the coke silicabrick rate?: To improve the thermal conductivity of silica brick for coke oven rate method:Manufacture of high density and high thermal conductivity of silica brick, adding additives such as CuO, Cu2O, TiO2, Fe2O3, (FeO), can improve the thermal conductivity of silica brick.

Q: What is the silica refractory products?: Refractory brick with silica content greater than 90%.

Q: Physical solid waste disposal: Preparation of silica brick pug, a certain amount of waste silica brick used to add ingredients, for the purpose of expansion and stress reduction products when firing, reduce cracks, improve the rate of finished products.
