Q:What are the advantages of refractory material?
Jingute WHL type, GDS type
Q:Does anyone know about the A-level fireproof materials?
rock wool external wall composite board, A1-level fire rock wool board, hidden slit rock wool board ¥ 30, A1-level fireproof mineral wool sound-absorbing board. What about the sound-absorbing sheet? glass fiber acoustic board engineering of the TV backdrop ¥ 85, A1-level fireproofing and thermal insulation rock wool board is hydrophobic thermal insulation, external wall thermal insulation materials ¥ 200, high temperature resistant calcium silicate board, LCFC/calcium silicate board is A1-level fireproof materials with high-quality and low-price ¥ 75, the prices above are from the internet for reference only, and the purchase prices vary according to the market.
Q:What's the difference of fire-resistant material's density, specific gravity and bulk specific gravity?
Q:What types does refractory floor include?
There are many types refractory bricks, including silicon aluminum refractory brick, the leading product in refractory bricks. And its high temperature resistance can reach up to 600 degree centigrade or more, so it is an excellent refractory brick. And this high-alumina refractory brick is very suitable for metal industry for its strong practicability. Another one is alkaline series refractory brick, including magnesite refractory brick, and these two bricks are good materials resistant to high temperature.
Q:Which industry does refractory belong to? Does it belong to construction industry?
I am engaged in construction. Refractory material does not necessarily belong to construction industry. Fire resistance is only a part of material performance. Indeed, there are many places requiring refractory accorded with fire resistant level.
Q:What brands are the best in the A-level refractory materials?
1 International (It is a well-known brand in the field of global boats and protective coatings, the products are famous for its safety, strength and smoothness, Akzo Nobel (China) Investment Co., Ltd.) 2 LANLING (It is a high-tech enterprise, and a large provider of industrial coatings, started in 1980, as well as a famous brand of Jiangsu Province, Jiangsu Lanling Chemical Group Co., Ltd.) 3 Champion (It is a high-tech enterprise who is involved in developing a number of industry standards, it is a industry-leading brand brand of Jiangsu Province Jiangsu champion coating Technology Group Limited) 4 BBMG Coating (It is a large coating enterprise and a leading brand of fire-resistant coating who draft up the fireproof coating industry standards, Beijing BBMG Coating limited liability company) I hope my answer can help you .
Q:Can anyone tell me the requirements of the refractory masonry??
Refractory materials actually have two functions. The first one is to improve the refractoriness and the second one is to improve the body plasticity of refractory materials.The higher the aluminum content is, the better refractory it will be. Of course, the content of aluminum in refractory materials can not be impoved only by using kaolin. Such raw materials that contain more aluminum as bauxite chamotte should be used as framework.So the content of aluminum in kaolin does not need to be too high and more than 38% of aluminum is enough. However, the viscosity should be taken into account. It will be better if the viscosity is better as the extra bentonite do not need to be added.The refractoriness that is is above 1400 degree is enough.
Q:Can anyone say something about what A-level fire-proof decorative material is?
The major products are material monomer A-level and composite A-level, now a lot of B-level material is wrapped in calcium silicate board. The foam cement overall composite is level A, such as phenolic aldehyde composite, as well as some of the foam paddings, monomer A-level includes rock wool, ultra-thin insulation panel and the like. But there are few products with real sound A level qualification. Many manufacturers are playing the edge ball with A-level fire rating examining reports and B-level system detection reports and records, but this situation will not last long, which will soon be clear.
Q:How to classify the grade of wall fireproof and thermal inuslation matertial?
The level classification of wall fireproof and thermal inuslation matertial: Grade A: incombustible building material: Material almost with no combustion. Grade B1: nonflammable building material: Nonflammable material has good flame resistance. It is difficult to fire in case of fire in the air or at high temperature. It is not easy to quickly spread. After the fire source is removed, combustion stops immediately. Grade B2: combustible building material: Combustible materials have a certain flame resistance. It will immediately burst into flames in case of fire in the air or at high temperature and is easy to lead to the spread of fire, such as wooden column, timber roof truss, timber beam, wooden stairs, etc. Grade B3: Flammable building material: It has no flame-retardant effect and is highly flammable. Fire hazard is very large.
Q:Who knows the model of fireproofing materials?
Models of fireproofing material: PC 6555 Bayer 6555 fireproofing PC 6557 Bayer 6557 fireproofing PC 6485 Bayer 6485 fireproofing PC 6385 Bayer 6385 fireproofing PC 6265 Bayer 6265 fireproofing PC 2865 Bayer 2865 fireproofing PC 4610 Dow 4610. Hope my answer will be helpful to you!
