Q:How many hours of the fire endurance time of the rock wool laminboard?
Limit is usually two hours. Pay attention to it please.
Q:What type of firebrick does TZ-3 represent?
Z represents a straight brick, T stands for common brick, common straight standard brick, -3 represents the length, and the specification is 230 * 114 * 65 (mm).
Q:Who knows how to divide the building fire grade and fire resistance grade?
I hope to help you building fireproof rank division is one of the most basic measure in building fire safety technical measures, Building's fireproof rank is divided into class one, two, three, four according to China's architectural design specification. Fire-resistant capability of the highest level is the strongest; Fire resistance of four level of the weakest. The fire resistance level of a building depends on the combustion performance and fire resistance of the building components that comprise the building. The so-called building component refers to a series of basic components, such as wall, foundation, beam, column, floor, stair, ceiling and so on. The judgment condition of the fire resistance There are three conditions for components' fire resistance limit to be reached, namely, the fire resistance limit of the building component: Loss of support and integrity; loss of time to fire the role of the time; as long as any of these three conditions is met, it will reach its limit of fire. Hope my answer will help you.
Q:Refractories for iron-making blast furnace?
This question is too professional - as far as I know, there are blast furnace noumenon bricklaying - trough slag runner fire-resistant model ~ main channel carbon rod ~ ramming mixes ~ ~ I do not know the specific details.
Q:Why the corundum can be used as refractory
Do you need white corundum Its main chemical element of corundum is the 99.3% aluminium oxide and it is sintered byelectric furnace, so it can be used as a refractory raw material, the other can also be used as grinding wheel. It is very useful
Q:How to distinguish the fire rating of rubber and plastic thermal insulation material?
According to GB 8624-2006 "building materials and combustion products classification", the division of the material's combustion performance grade is changed from five levels of level A (homogeneous material), A (composite sandwich material), B1, B2 and B3 to seven levels of A1 , A2, B, C, D, E and F or A1f1, A2f1, Bf1, Cf1, Df1, ef1 and Ff1 or A1L, A2L, BL, CL, DL, EL and FL . The level B1 rubber and plastic fireproof and thermal inuslation matertial is the best, but the most commonly used one is level B2. Hope it will help you.
Q:What is the function of refractory in ceramics?
Refractory is used as materials of kiln,sagger and kiln car for ceramic sintering. Its refractoriness is higher than ceramics, and the essential material and tool for ceramic sintering.
Q:What characteristics do A grade external wall fireproofing material have?
For characteristics of A grade external wall fireproofing material, its main raw material uses cold resistant and thermal insulated, environmental protection and energy saving material with good insulation, keeping the indoor temperature steady and making the environment more comfortable. It is several times better than other masonry in overall strength and resist capability, and it can also hang heavy objects such as air conditioners by directly nailing or installing expansion bolts. Single point hanging machine can withstand heavy objects with the weight of more than 45kg. It can also be directly fixed to the tiles, wallpaper, wooden plaques, paint, etc.
Q:How to distinguish the fire resistant level of the rubber and plastic thermal insulation material?
It is divided into level A, B1, B2 and B3. According to the current "burning behavior of building materials classification method", Level A insulation material is a non-combustible material, which belongs to YT. However, from the point of view of the current market , level A insulation material are very few, only glass wool, rock wool board, foam glass and vitrified micro bead. However, compared with level A insulation material, the more welcomed by the market is the organic insulation material. This is characterized as thermal insulation material, which is divided into three levels: level B1 is flame retardant, level B2 is flammable and level B3 is flammable. The level B1 nonflammable thermal insulation material is determined according to the fire endurance of the material. And different parts of the material are divided differently! Such as the common EPS / XPS insulation boards through special treatment of adding flame retardant. . Level B2 combustible insulation material is commonly the EPS expanded polystyrene foam insulation board and XPS board, that is, the ordinary plate. This material has low ignition point, and releases large amounts of harmful gases in the combustion process . Level B3 flammable insulation material is commonly the thermal insulation material taking polystyrene foam as the main material. Since this material is highly flammable, it has been out of the external wall thermal insulation materials. As for the civil construction insulation materials, China's current popular building insulation materials in the market are mainly made of three organic foams: EPS (molded polystyrene board), XPS (extruded polystyrene board) and PU (polyurethane).
Q:What is the principal part of silicious refractory material
Silicon nitride and aluminite powder as well as dextrin
