Specifications

Fused Mullite :
1,high purity fused mullite
2,provide mullite with different grades and size

Description:

Mullite is a raw material with high heat resistance. At present, there are mainly high purity fused mullite, ordinary fused mullite, finely sintered mullite with all natural bauxite and caustic-burned mullite.

Mullite of Ruishi Brand is made of high quality pure natural mullite ore, melted from the advanced industrial furnace with high temperature. It is featured by uniform expansion, excellent thermal shock resistance, high softening point with load, low elevated temperature creep value, high hardness, good resistance to chemical corrosion etc.

Q:how about the performance of aluminum silicate fire proof thermal insulation?
aluminum silicate fire proof thermal insulation board has a good performance. it is a artificial board that separates the wood and plant fiber by mechanical and chemical methods and mixed the adhesion agent and water-proofing agent, molding by high temperature and high press. MDF(medium density fibre board) structure is more even than natural wood. it avoids rot, moth-eaten and other problems, while medium density fiber board has small expansion and contraction, which is easy to be processed. Since the surface of medium density fibre board is smooth, the board is easy to paste a variety of finishings, which makes furniture more beautiful. A variety of decorative wood-based panel is to embellish their homes.
Q:The performance of refractory material
As for easticity modulus, you can serach for information on the Internet or specialized books.
Q:Can anyone tell me what is a high alumina refractory?
Refractories refer to a class of inorganic non-metallic materials whose refractoriness are no less than 1580 ℃. Refractoriness is the Celsius temperature when cone-shaped samples can resist high temperature without softening and melting down in the absence of a load. But it is not accurate to define refractory merely by judging that whether the refractoriness is no less than 1580 ℃. Currently, the materials whose physical and chemical properties allow them to be used in high temperature environments are called refractories. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, power and so on, among which the metallurgical industry is the largest demander in this regard, accounting for 50% to 60% of total output. Hope it will help you out!
Q:how does the fire endurance of first rate fire resistant window?
how does the fire endurance of first rate fire resistant window? I really don't know it and I need a specific direct and detailed answer!
Q:What's the requirements of fire-fighting criteria of heat insulating material?
Specific provisions go as the following article 8: roof grassroots adopted duration of fire resistance is the non-combustible component that shouldn't less than 1.00 h's. Its roof insulation materials should not be below B2; Otherwise, the combustion performance of insulating material should not be below the B1 level. Article 9: The junction of the roof and wall, the insulation layer around the opening part of roof should use the grade A thermal insulation material to set level fire-fighting belt that width is not less than 500 mm. Article 10: the roof waterproof membrane or flammable insulation layer should adopt incombustible material to cover.
Q:How is the fire endurance of the fireproof paint?
Fireproof endurance. fire resistance test of certain building components showed by standard time temperature curve from starting of fire to lose the supporting capabilities or its integrity or fireproof property. The fire proof endurance is 5hours.
Q:Are fire materials poisonous after burning?
Refractories burning after the smell of toxic, gases are generally silica, alumina, sulfur oxides and so onRefractory material is not less than 1580 degrees of refractoriness, better thermal shock resistance and chemical erosion, low thermal conductivity and low expansion coefficient of non-metallic materials. Acid refractory with silicon oxide as the main component, are commonly used in brick and clay brick. Silica is silica containing more than 94% silica products, raw materials used in silica, silica and other waste, the acid resistance of slag erosion ability, high load softening temperature, volume shrinkage after repeated burning, or even a slight expansion; but it is vulnerable to the erosion of basic slag, thermal shock resistance is poor. The brick is mainly used for thermal equipment of glass furnace, coke oven, acid furnace etc.. Clay brick with refractory clay as the main raw material, containing 30% to 46% of alumina, weak acid refractory material, refractory material, good heat shock resistance, resistance to acid slag, widely used.
Q:What are the insulation fireproofing materials?
Insulated shoes, insulated gloves, tape (cloth, plastic, as well as waterproof) yellow wax tube, mouth care, fireproof (ie asbestos cloth is sold by jin) there is pressure-caps black tape, waterproof tape ,casing. There are glass fiber needle felt is widely used in electrical, chemical, construction, transportation, automotive and other industries interlayer insulation and silencer system, and used as an insulating fireproof material.
Q:What are the meanings of azs, 34% and ec in fused brick?
The fused brick, also called zircon corundum brick, is shorted as AZS for three chemical components in Al2O3-ZrO2-SiO2 ternary diagram. I don't know the meaning of EC.
Q:What is the function of red stone refractory materials
