Glass Industrial Silica Bricks

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: What is the effect of the content of silicon nitride in silicon nitride bonded silicon carbide brick on the use of electrobath? Thank you: Small fluctuations in the chemical composition do not have a significant effect on use. The key is the operation of the electrolyzer in production to determine whether the side wall will be damaged.

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?: Brick, high thermal conductivity has been greatly improved in terms of morphology, crystal structure, physicochemical index. The structure and morphology of high thermal conductivity of silica brick,Structure and morphology of high thermal conductivity and the traditional brick brick magnified 20 times were compared, high thermal conductivity silica pore size distribution is more uniform and finer.

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?: The content of SiO2 is 98.23% crystalline silica as raw material, with sulfite pulp liquid as binder, millscale and lime as mineralizer, by Jin Hongshi (TiO2) as additive, can improve the rate of thermal conductivity of silica brick for coke oven. When the rutile content is 1.5%, the coefficient of thermal conductivity of silica brick for coke oven is 2.66W/ (m.k).

Q: Brick: An acid refractory consisting mainly of quartz and square quartz and a small amount of residual quartz and glass.More than 94% silica content. True density 2.35g/cm3. With acid resistance, slag erosion performance. Higher high temperature strength. The softening start temperature is 1620~1670 degrees. Long term use at high temperature without deformation. The thermal shock resistance is low (the heat exchange in water is 1~4 times). The natural silica is used as the raw material, and a proper amount of mineralizer is used to promote the transformation of quartz into quartz in the body. Slowly sintered at 1350~1430 DEG C in the reducing atmosphere. When heating up to 1450 degrees, the total volume of 1.5~2.2% expands, and the residual expansion can close the kerf and ensure the airtight and structural strength of the masonry.

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

Q: High temperature refractory material?: Basic refractories in Magnesium Oxide and calcium oxide as the main component, the main products are magnesia brick, magnesia chrome brick, magnesia zirconia brick, magnesia brick, magnesia spinel brick, magnesia calcium brick, dolomite brick and the latest development of magnesia spinel brick and so on. With Magnesium Oxide (MgO) more than 80% of the refractory brick called magnesia brick,
