Q: How to distinguish the construction fire-proof material rating?: Currently the national standards divide building materials as follows: A1, A2, B, C, D, E, F. External wall thermal insulation fire?rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. Class A is non-combustible, class B1 flame retardant, class B2 combustible, class B3 flammable. Combustion performance grades of building materials and products are divided into class A1, A2, B, C, D, E, F. And grading of flooring materials and pipeline thermal insulation materials is also stipulated separately, whose combustion performance grade is distinguished by the subscript fl and L respectively. ie. Combustion performance grades for ordinary building materials and products are A1, A2, B, C, D, E, F; combustion performance grades for paving material are Alfl, A2fl, Bfl, Cfl, Dfl, Efl, Ffl; combustion performance grades for pipeline thermal insulation material are A1L, A2L, BL, CL, DL, EL, FL.

Q: What type of firebrick does TZ-3 represent?: It is the standard brick.

Q: What are the models of bauxite with high alumina?: China Ferrous Metal Industry Corporation released the industry standard of bauxite (YS / T78-94) in 1994. According to this standard, bauxite can be divided to sedimentary diaspore, stacked type diaspore and lateritic gibbsite. According to the chemical composition, it can be divided into nine trade marks as LK12-70, LK8-65, LK5- 60, LK3-53, LK15-60, LK11-55, LK8-50, LK7-50 and LK3-40. In addition to the provisions of chemical composition of bauxite, the standard also requires that the water of sedimentary diaspore shall not exceed 7% and water of stacked type diaspore and lateritic gibbsite shall not exceed 8%. Moreover, particle size of bauxite should be not greater than 150mm. Bauxite shall not be mixed with clay, limestone and other debris.

Q: I am a manufacturer of refractory materials. I would like to receive some orders from abroad. I would like to know what foreign trade companies in Dalian place foreign orders abroad: You don't give a cent to this question, no one will answer it

Q: What is the appropiate thickness if fire resistant time for ultra thin steel structure coating is 2.5 hours?: Hello steel structure can adopt surrounding concrete or brick, fireproof coating, fireproof board coating and composite structure for its fire resisitance. Fire resisitance board can be divided into thick fire protection plate and thin plate, the thickness of the plate thickness of the fire is between 20 ~ 50mm, mainly includes calcium silicate fireproof board and expansion boring stone fire board, the main varieties are KB board, CF; thin fireproof plate is between 6 ~ 15mm thick, the main varieties include enforced short fiber cement plate, ordinary enforced fiber silicate calcium board and glass cloth reinforced inorganic board.

Q: What kind of refractory materials are used in the intermediate frequency furnace?The domestic boric acid can be used as a lining?, how much is the rate?: Acid, neutral, basic and composite materials are used in intermediate frequency furnace. Boric acid is used according to the type of steel, the specific ratio is too generalized, and it shall be determined when the type of steel is detailed.

Q: What is the type of heat resistance property of high temperature electric furnace ?: According to the levels of refractoriness : Common refractories: & Gt: 1580 ℃ ~ 1770 ℃ advanced refractories: 1770 ℃ ~ 2000 ℃ AAA refractories; 2000 ℃

Q: Who knows about the fire endurance of grade C fire doors?: The fire endurance of grade C fire doors is no less than 0.5 hours. As the key role of family fireproofing, fire doors is particularly important. It can be classified according to the fire endurance and thermal insulation performance: The fire endurance of grade A fire doors is not less than 1.5 hours; that of grade B fire doors is not less than 1.0 hours; and that of grade C fire doors is not less than 0.5 hours. We can choose in accordance with different needs, but commonly used fire doors are grade A and B fire doors now.

Q: Who knows what material is in the center of fireproof rolling curtain?: made of inorganic super fireproof rolling curtain: Glass fiber cloth ceramic fiber cloth (reinforced stainless steel wire) ceramic fiber blanket aluminum foil cloth. Hope my answer will help you.
