Strong wear and heat resistance

1. Advantage

 

White fused alumina is made of quality alumina powder by smelting at 2050 °C.

 

1). High purity

2). Good self-sharpening

3). Less thermal diffusivity in grinding

4). Strong acid-alkali resistance

5).Excellent high-temperature stability,

6). Low porosity, etc

Q:What's the maximum temperature that the refractory ceramic fiber cloth can endure?
While the refractory ceramic fiber cloth is different in high temperature resistance, and in general it can endure the high temperature of more than 1000℃. Ceramics in daily use and art ceramics: Bone china and Guangdong chinaware can generally endure the highest temperature of 1100℃. Jingdezhen porcelain and ceramics: They can generally endure the highest temperature of 1280℃-1340℃, and some special ones can endure the highest temperature of 1400℃. Industrial ceramics: Some of them can endure the highest temperature of about 2600℃. (alumina ceramics: their melting point is 2050℃, and boiling point is 3000℃).
Q:What is the biggest difference between refractory bricks and clay refractory bricks? Where can I find information on the refractory bricks?
You can look up knowledge manual of refractory material to find phosphatic material, etc. Xinjiang refractory bricks, castable refractory, refractory material, silicious, corundum and alumina-magnesia: High alumina and clay refractory bricks can be divided into
Q:Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?
Why is the apple screen so small?
Q:What is the strength of high strength refractory material?
Hefei Jiule decoration is answering your question: Use corundum as aggregate, high alumina cement as binder, mixed with a number of additives prepared, with high strength, and a hydraulic refractory casting material used in hot furnace lining at high temperature.
Q:what is the common materials for home fireproofing material?
1, lumber core 2,decoration panel 3 , plywood 4 density board 5,chipboard 6 fireproof?panel, 7.gypsum board Hope to adopt my opinion
Q:The difference between refractory and thermal insulation material
In simple terms, refractoriness is different. The refractoriness of refractory is high while that of insulation material is low.
Q:Where is refractory used? Thank you!
Currently, refractory is widely used as inorganic nonmetallic material of production equipment lining in metallurgy, ceramics and other industries. The current definition of refractory does not only depend on whether the refractoriness is above 1,580℃.
Q:Fire rating of decoration materials
You can refer to (code for fire protection design of buildings)
Q:What's the poured refractory material?
According to its category, raw material of basic refractory: Mainly magnesite (magnesia), dolomite, lime, olivine, serpentine, high alumina material (sometimes neutral); main neutral raw material: chromite, graphite, silicon carbide (artificial).
Q:Who knows the roofing fireproofing and waterproof material?
If you should do home water proofing, I recommend the acrylate waterproof coating with high elasticity of Qinglong waterproof, because it has good aging resistance, extensibility, elasticity, binding property and film-forming property; waterproof layer is a closed system, the overall waterproof effects are very good, especially for the construction of heterotypic structure base and roofing, walls, toilet and bathroom, basement and other buildings waterproof and anti-seepage engineering in the conditions of non-permanent immersion;
