$High Alumina Low Cement Refractory Castable$

Q: How can refractory materials be divided?: Refractory materials in China can be roughly divided into refractory products and unshaped refractories.

Q: Do you know the refractories?: The so-called main component refers to the first phase and the second phase component, and the content accounts for about 90% of the total chemical composition. The development of modern technology more and more number of refractory material ingredients, so the second phase, the third phase component, adjusting the second phase, the third phase composition can generate a new technology in the chemical composition of the first phase beyond the limitations of the classification, a classification method is the most commonly used.

Q: How to do environmental impact assessment for refractory Co., Ltd.: 1, first of all, the EIA unit and the construction party signed the EIA contract. The contract is only legally valid. Generally speaking, the contract will indicate that the first payment has been received before the work begins.2. Collecting information. This is a very important link in the EIA, which is directly related to the quality of the eia. There is a great variety of data,Generally, the construction party will write a list of environmental impact assessment information.

Q: What is the use of refractory?: It is equivalent to a protective layer. It can be used to protect structural materials from being direcctly attecked by high tempereture or internal gases. General structural materials are steel, so the main function is resistant to fire and high temperature. In literal meaning, refractory is a fireproof material. Steel is easily deformed and wore. Structural materials can not directly touched with solid and liquid. Refractory materials are generally used as a protective lining of structural material, so it is necessary to be protected.

Q: Does refractory belong to stone, building materials or other?: Refractories belong to organic non-metallic materials.

Q: who knows the fire resistant level of fireproof gypsum board ?: The most commonly used ceiling decoration materials rates B1, including gypsum board, fibrous plaster, cement particle board, mineral wool sound-absorbing panels, glass wool decorative acoustic?panel?absorber, perlite decorating acoustic board, nonflammable plywood, nonflamable medium density fiberboard, mineral wool decorative board, flame retardant wood, aluminum foil composites, flame retardant phenolic plywood, aluminum foil glass fiber reinforced plastic composite materials. The fire gypsum board fire rating can reach A. Of course, many of the suspended ceiling gypsum board of inferior quality rates below B1. plasterboard is non-flammable B1 level products. There are introductions in Fireproof Specification of National Standard Building Interior Decoration Design. plaster board mounted on steel stud can be used as A level decoration materials. in accordance with the national fire safety rules on fire durance of walls and ceilings and other components. we can not simply say whether a piece of gypsum board can meet the requirements.

Q: What thickness is needed of the ultra-thin fireproof paint with a fireproof time of 2.5 hours?: Fireproof of steel components can adopt outsourcing concrete (or laying bricks method), fireproof coatings, fire prevention board coated and composite structure. Anti-firing plate can be divided into the fire protection lamella thickness plate and thin plate. Fire protection lamella thickness plate is of 20 ~ 50 mm. There are mainly calcium silicate and decayed stone of fire prevention board fire board, main varieties KB board, CF board; Fire sheet thickness is between 6 to 15 mm and the main varieties have short fiber reinforced cement pressure plate, fiber reinforced ordinary calcium silicate board and glass cloth reinforced inorganic plate. I hope you can be satisfied.

Q: Does anyone know the fire endurance of steel stud partition?: The fire endurance degree is 1 hour. which is in line with the national building material fireproofing test standards. CaSo4.2H2O is molecular gypsum molecular structure formula, containing 20% ??water, crystal water and free water, when putting on fire, 10% of the surface water will slowly evaporate, remaining10% of crystal water. It is a class A fire retardant material itself. The longest time can be 4 hours.

Q: How to divide the fire resistant level of construction thermal insulation materials?: Combining three versions of GB8624 (1997,2006,2011), external wall thermal insulation fire?rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. There are many technical indexes for specific division. And it is mainly determined in accordance with the national standard GB8624 Building materials combustion levels.
