Product Description

 

Bauxite is earthy mineral which consists mainly of Al2O3 , a kind of hydrated alumina containing impurities. According to the usage, It can be divided into the levels of Metallurgy, chemical industry, grinding, cement, and refractory. Clinker is pale yellow and dark grey. It is mainly used for high aluminum refractory material, and also can be used to make the fused corundum. Our materials of calcined bauxite is mainly D-K Style Bauxite Ore. Our specification is as follows,

Q: What is the role of adding chromium oxide green in unshaped refractory materials
Generally, less is added in corundum or corundum spinel refractory material, but it can significantly improve the material performance such as high temperature strength, erosion resistance, thermal and shock stability, etc.
Q: Why the refractories should be waterproof and wetproof
It is necessary to like magnesium carbon, waterproof and wetproof is more important. There is a variety of refractory materials, in general, basic is defective, and wherein the binder and additives water will lose their effect, the relationship is not very high aluminum large amount of water determines how much of the performance after the hydration will affect the strength and high temperature performance ;; hydration & quot, just need a little package like magnesium and calcium-based product itself readily react with water to calcium oxide, magnesium, chromium is not all the material goods have waterproof ordinary bulk materials need to add water before use
Q: what's the varieties of fire-proof?sealing?material?
Fire blocking material currently on the market include: fire stopping board, foam blocking material, flame resisting module, fire-resisting sealant, flexible organic caulking, WXY-II and fire retardant bag, etc. fire-proof?sealing?material is widely used in building construction and can ensure high-temperature flame and smoke from fires not spread to another fire?compartment, different buildings generally use different sealing methods. Pipeline is generaly sealed by pouring concrete board or mortar.
Q: Does the production of refractory belong to advanced technology?
Refractories belong to the area of new materials which is one of the eight areas that are supported by the state. Whether it can be declared as high-tech enterprises or not depends on the intellectual property, personnel and finance of the company.
Q: What is the concept of lightweight refractory material?
Lightweight refractory material has high porosity, mechanical strength and erosion resistance. Compared with normal refractory bricks, it is a kind of refractory material with large volume shrinkage in high temperature, low thermal conductivity and small bulk density. It is used as thermal insulation material in industrial furnace and other thermal equipments. It has poor wear resistancel.
Q: What is the most reasonable drying heating curve of magnesia refractories? Products of less than 0.5T
o
Q: What defect does fused cast refractories have ?
What defect doesfusion-cast refractory material have ? In glass production, in addition to refractory as a building material and consider its durability, we still must attach great importance to its influence on glass quality. In such cases, the impact on the quality of glass is mainly the defects that eroded down refractory materials mixed in the glass, thus being prodeced of grass products. Defects are mainly foreign body defects such as sand, knot and wave reinforcement. What may directly affect the quality of glass are sidewall block and brick kiln bottom. I hope my answer can help you.
Q: Who know about the knowledge of acid refractory material? Please explain in detail.
Refers to the silicon dioxide
Q: What's the A class fireproof and thermal inuslation matertial for external wall?
It is roughly divided into thermal insulation mortar, phenolic foam board, rock wool board, foamed cement board, etc. Insulation mortar is quite good for its simple construction, convenience and low cost, but its production is too simple to make fake products easily. If you want to use the material, it is suggested to find a large plant with complete procedures such as provincal records of production and use, city records, test report above provincial levels, national fire inspection report, design drawings sheets of Department of Construction, etc. If there is lack of any one, it is unsafe. Hope my answer is helpful for you.
Q: who knows the fire endurance of fireproof coating?
this is not specfied , depending on design requirements. The products we made have fire endurance from 1to 4hours . We have not done any higher.how is the fireproof coating in improving fire resistance of building components? finishing fireproof coating; wood fireproof coating; fire-resistant coating for steel structure, fire-resistant coating for concrete structures, tunnel fire retardant paint, fire retardant paint for the cable. Fire retardant coating is composed of the base materials (that is film forming substance), pigments, ordinary coating additives, fire retardant agent and dispersion medium. In addition to fire retardant agent, other components functions the same as in ordinary coating, but its performance and thickness are specifically required.
