- Q: Who knows the setting requirements of roofing fire barrier zone?
- First, the the minimum of fire barrier width is greater than 30cm, and the thickness should be same to the thickness of the insulation materials. Fire barrier zone insulation board must do the whole area sticking construction with the base wall during the construction. Fire barrier zone insulation board is required to assistant binding by anchor bolt, anchor bolt must suppress the underlying mesh. Second, Fire barrier zone should be set at the upper position of door and window openings, the distance between the low edge of isolation belt and the upper edge of the window must be less than 50cm. The thermal resistance of fire barrier zone must be half than EIFS thermal resistance in the cold northern areas, while the thermal resistance of fire barrier zone must be three times than EIFS thermal resistance in the hot summer and cold winter area. Third, When the fire barrier zone is set on the edge of the window, fire barrier zone at the upper part of the window should do flanging when sticking, flanging glass fiber mesh must exceed 10CM than firebreak insulation board. Flanging network, underlying network and surface network can not be overlapped or butted at the top of the window. I hope you can be satisfied
- Q: What's the function of aluminium dihydrogen phosphate on the refractories?
- Mainly used for binder of high-temperature furnace refractory. Characteristics of liquid aluminum dihydrogen phosphate, castable. solid used for refractory spraying coating, chamotte, ceramic construction, which has high break resistance after being dried in 350-500 ° C, phosphate bricks. Characteristics of the solid aluminum dihydrogen phosphate, binding agent used for castable and casting industry: together with the refractory aggregate, ramming mixes at room temperature: Easy to mix, crush resistance, hydration resistance, chamotte, will not become soft even if soaked or boiling in water, molding. Liquid use refractory spraying coating, mainly used for corundum, chrome corundum water gap in refractory industry. The production of chrome aluminum zirconium corundum brick for water-coal-slurry gasifier is especially suitable for site construction applications mainly used for the electrical industry, high-temperature kiln and furnace, hardener, after mixing between 90-110 ° C for 4-24 hours at a constant temperature, forming strong bonding strength, electrical insulation, heat treatment resistance furnace
- Q: How long is the duration of fire resistance of hollow glass magnesium board
- Hollow glass magnesium board features fire prevention, waterproof, tasteless, non-toxic, not frozen, not rot, not crack, unchanged, non burning, high strength and light weight, convenient construction, long service life and so on, and it has more characteristics among products of the same kind nationwide. Its fire resistance limit is 0.65℃.
- Q: Refractory materials are needed for casting metallurgy.
- High quality refractory materials can not be separated from the process of smelting metal and casting moulding, because the quality of melting furnace, iron / steel ladle directly affect the chemical composition of the metal liquid, and exert irretrievable influence on comprehensive quality of castings. Classification of refractory materials used in foundry smelting process: refractory brick, siliceous brick, high alumina brick, corundum brick, magnesia brick, magnesia brick, magnesia carbon brick. Unshaped refractory materials: ramming material, castable, refractory cement, silica, magnesia, coating material and light insulation material etc.
- Q: Which refractory material is better in China? Industrial furnace, mainly in non-ferrous industries, glass kiln, cement kiln business.
- Such solid nano microporous insulation material with nano inorganic refractory powder special, with a huge surface area, nano particles contact between the minimum point contact point contact thermal resistance is very large, the heat conduction effect of the material becomes very small, resulting in heat conduction coefficient of solid such nano porous insulation materials very small; nano pores formed of nanoparticles, the average size of 20 nm, and the average free path of molecular thermal motion at room temperature under static air is 60 nm, thus locking the air molecules in powder within nano pores, making the micro convection heat transfer effect between the stationary air molecules disappeared. The room temperature thermal conductivity of solid such nano microporous insulation material is lower than the static air; at high temperature, the main effect of heat transfer heat radiation, Good energy-saving insulation materials with nano microporous infrared additive special, stop at a high temperature and reflected infrared radiation, reduce the heat radiation effect to the lowest point, the radiation heat transfer coefficient of materials under high temperature is reduced to the lowest value.

- Q: What is high alumina refractory?
- High alumina refractory: High alumina refractory products, with high refractoriness, compressive strength and refractoriness under load, it is used for masonry of a variety of large-scale blast furnaces such as steel furnace, air heating furnace and electric furnace, and for high-temperature parts of thermal equipment like rotary?kilns.
- Q: Who know about the knowledge of acid refractory material? Please explain in detail.
- Abrasion resistance of fire resistance material depends on the material group and structural material. The abrasion resistance of dense single crystal materials depends on the hardness of mineral crystal. The higher the hardness, the more resistance the material is to abrasion. non mineral crystals with fine grain material has a high wear resistance. The abrasion resistance of materials is related to bulk density or porosity. Aluminium refractory material can resist a temperature as high as 700~900 degree within the elastic range. The higher the temperature, the lower the resistance. Abrasion resistance will be increased with elastic modulus as temperature increase. In many cases, refractory material will often cause a lot of harm due to mechanical abrasion.
- Q: What are the new types of refractories? What are the characteristics? Their applications and developments?
- A new type of refractory materials are: A12O3-TiO2-SiO2 refractories, MgO-A12O3-TiO2 refractories, MgO-CaO-TiO2 refractories, MgO-SiC-C refractories, nanotechnology MgO-C brick, MgO-AL2O3-AIN refractories, MgO-La2O3 refractories etc..
- Q: It the Special Fire-Proof Material belonged to ceramics? Is there a national standard of the Special Fire-Proof Material?
- The fiber and reinforcing material of the metal ceramic is also belonged to the Special Fire-Proof Material. ~~~~GB is too much trouble, GB online should ~~~ Lei Bao Refractories for you. The high temperature inorganic coating. 5. The refractory compound. 3. The high melting point oxide. You can search it on the internet according to the classification~~~~ The special refractories can be divided into five categories: 1. metal ceramic
