Q:How to classify the grade of wall fireproof and thermal inuslation matertial?
External wall thermal insulation materials are mainly divided into grade A, grade B1, grade B2 and grade B3. In accordance with the current "Combustion Performance Classification Method of Building Materials", grade A thermal insulation material is incombustible material and belongs to inorganic heat preservation material. However, grade A thermal insulation material is few in terms of the current market. There are only JETCO YT inorganic active wall thermal insulation material, glass wool, rock wool board, foam glass, vitrified micro bead and grade A fireproofing thermal insulation board. However, compared with grade A thermal insulation material, the more welcomed by the market is the organic insulation materials. Thermal insulation material that is determined as grade B is divided into three levels. Grade B1 is grade is flame retardant. Grade B2 is combustible. Grade B3 is flammable.
Q:Why should graphitic refractory materials be used now that graphite can burn?
Materials for refractory must have the following characteristics and properties: 1, high stability: Anti-oxidation, anti-reduction, thermal decomposition; 2, high melting point : 2800℃; 3, low price. Graphite has all three characteristics and properties, especially melting point and stability.
Q:Why the corundum can be used as refractory
Corundum has high refractoriness, so its high temperature performance is very good.
Q:what needs to be noted when choosing and using blast furnace fireproof materials?
it depends on the size of the blast furnace. below 200 cubic meters alumina bricks and carbon brickcan be used. 200 cubic meters and above are currently integrated bottom, not the same as the size of the cubic level, varying in the use of refactory. I hope my answers above are helpful to you and your ideal anwers.
Q:what's the materials of fireproof housing?
what's the materials of fireproof housing? what's the fire rating? how much is it? What are the key installation points?
Q:The principle of choosing fire-resistant material in Thermal Energy and Power Engineering equipment.
Different thermal technology equipment has different operation condition and select different refractory material. We should take economical and practical as principle.
Q:what is the fireproofing material of engine room? who knows it ?
1. The new type fire retardant coating in fire retardant coating, the expanded vermiculite, expanded perlite heat insulation material and cenosphere adiabatic powder, etc. These inorganic component, is a major part of the thick coating type of fireproof coating, and they also are the major factor affecting the level of performance of fireproof coatings. The fireproofing thermal insulation properties of fireproof coating, is mainly determined by the fire back surface temperature of this factor, but also related to the fire endurance. If it reaches the same temperature for a longer time, it shows that it's fireproof thermal insulation is better, and the fire endurance therefore is higher. 2. The new fireproof board new fireproof board now is welcomed by the people and the important factor is its environmental protection, and with the increasing high-rise buildings, the fire protection requirements and strength requirements are also rising, it is a big challenge for the performance and standard of the fireproof board.. Now fireproof board is mainly used siliceous material or calcareous materials, and then mixed with the fiber material, lightweight aggregate, adhesives and chemical additives, it is not only be fireproofing, but also improve their thermal insulation performance, and light weight, good carrying capacity, good durability, no aging problem, more importantly, it is good in environmental protection.
Q:What kinds of refractory materials that uses a-Al2o3 powder? What are the purpose of it?
04La-Al2O3 powder is a alumina powder whose raw material is industrial aluminum oxide which has been calcined at high temperature. It is a good polishes for ceramics and jade, meanwhile, it is also an important raw material for high-end refractory materials. The technical indicators parameters A1023 mark A1535 chemical composition AL2O3≥ 99.92 3%, ≥ 3.10FE203≤ 0.799 Refractory calcined alumina powder (a-Al2O3) 1.2 true density (g & # 47, by fully ground powder made of different fineness .O.10 0.07 0.04NA2O≤ 0.93a-Al2O3 (%) ≥ 95 95 primary crystallization average grain (um) 2 ~ 3 3 ~ 5 average particle size (um) 40 ~ 602.6SIO2≤ 0.1 0.15B2O3≤ - 0, glass, engineering ceramics typical use electronic ceramic insulating ceramic refractory ceramic wear 3
Q:What is the function of red stone refractory materials
Q:Who know what kind of fire shutter fire rating are there?
The fire resistance limit of high steel structure reduces the loss of fire, achieves remarkable results. The specification is mae in order to unify the application technical requirements of the design, construction method and quality standard of the steel structure fire retardant coating, and ensure the application effect, safety. The specifications is formulated in accordance with national engineering construction of the relevant policies and "giving priority to prevention, combining fire prevention and fire extinguishing. investigated characteristics of steel structure fire in China, summed up the experience of fire resistant coating for steel structure, and absorb domestic and foreign advanced technology and scientific achievement in fire retardant coatings for steel structures, and repeatedly solicited the relevant scientific research and design, production of construction, colleges and universities, public security department
