Q:Which industry does refractory belong to?
It belongs to construction industry.
Q:Fefractory of aluminium oxide.
It can be refined into castable refractory and refractory bricks, according to temperature rating. There are shaped refractory material and shapeless refractory material, and ceramic fiber. So it must be specific. There is a large range of refractory, which basically contains the aluminium oxide.
Q:What are the material requirements of class A fire resistant door ?
What are the material requirements of class A fire resistant door ?
Q:What are the requirements when producing fireproof materials by kaolin?
Kaolin refractories in fact play a role in two aspects, one is to improve the refractoriness, the second is to improve plasticity of the the refractory . Aluminum content the higher the better, of course, but kaolin is not the only material to improve the content of aluminum, using materials that contain higher content of aluminum such as the bauxite chamotte. So the content of kaolin aluminum does not have to be too high. over 38% is fine. viscosity is important and strong viscidityis better without having to add bentonite. Refractoriness above 1400 degrees is enough.
Q:What's the A class fireproof and thermal inuslation matertial for external wall?
It is a kind of green and environmental protection inorganic material, free of harmful substances like asbestos, benzene, formaldehyde, etc. Its fire resistance can be up to A1grade non-combustible material, which means it can endure the highest temperature of 1400 ℃. It is thermal insulating with low heat conductivity and high heat storage coefficient. It has good weather resistance, finished product stability, anti hollowing, crack resistance, wind pressure and shock resistance with the same service life as buildings of 70 years. It is water-fast and moistureproof, breathable but waterproof, and fungusproof without influence from steam. It is convenient in construction which omits many procedures of panels construction. Once the second plastering is finished, the construction is completed, which greatly shortens the construction period. It has good adhesive property with various base planes, and meanwhile its external exposed surface can choose coating, facing brick, aluminum sheet, marble, etc. It saves money. Excellent construction technology reduces the construction cost. It effectively prevents the panels from leakage at the external wall, window, eave, etc. which saves the subsequent maintenance fund. It provides timely delivery. With sufficient supplies of raw materials and convenient production, it is fast in delivery.
Q:How to understand qualitative and qualitative refractory materials?
Such as amorphous refractory castable, referred to as bulk loading, cast material, ramming material, refractory clay etc., utensils and other special products. Amorphous refractory material products, refractory heat insulating bricks and experimental and industrial crucible, spraying materials, such as burning bricks, electric melting brick, turn it into required shape and process heat treatment in where it is used.
Q:Can anyone say something about the curtain wall fire-proof material key sealing point?
When sealing the gaps between glass?curtain?wall and floors of all layers and the outer edge of the partition with rock wool or mineral wool, its thickness should not be less than 100mm and should be filled densely; Rock wool or mineral wool for horizontal smoke prevention zone between floors should use galvanized steel sheet whose thickness is not less than 1.5mm to support; The gaps between supporting plate, major structure, curtain wall structure and supporting plate should be filled with fire-resistant glass, whose fire endurance should meet the design requirements. Fire-resistant glass for curtain wall are mainly include monolithic fire-resistant glass as well as the hollow glass and laminated glass made by monolithic fire-resistant glass.
Q:I wanna ask that magnesium oxide is refractory?
Yes, Magnesia belongs to ionic crystals, the oin of magnesium has two charge, oxygen and magnesium ions are relatively small radius, these two factors make a lot of magnesium oxide lattice energy, high melting point is up to 2800 degrees Celsius. Because the magnesium oxide is stable and not react with water, it is widely used as a refractory material.
Q:What are the new refractories?
Most are ordinary refractories.
