Q:Who knows how many fire heat preservation material are there?
Fire proof board is a fire refractory building material for surface decoration, widely used in interior decoration, furniture, kitchen cabinets, laboratories mesa, walls and other fields. Fire board is base paper (titanium powder paper, kraft paper) processed by melamine and phenolic resin, high temperature and high pressure. 1 mineral wool board, glass wool board: mineral wool, glass wool insulation. It does not burn itself, have good performance such as high temperature resistance, light quality. Such plate have evolved into plate with inorganic adhesive material as base material, mineral wool, glass wool as reinforcing material plate. 2 cement board: High strength, wide source. In the past, it is used to make fire prevention ceiling and partition wall, but its fire resistance is poor. Cement concrete component has good heat insulation and sound insulation performance. It can be used as the partition wall and the roof panel.
Q:What is glass furnace used high-grade refractory materials?
It is said that building a furnace need 30 million? After the ignition, it can't be gone out. Only at the waste to maintenance?
Q:Which plant need to make refractory mould?
Q:What defect does fused cast refractories have ?
In glass production, in addition to refractory as a building material and consider its durability, we still must attach great importance to its influence on glass quality. In such cases, the impact on the quality of glass is mainly the defects that eroded down refractory materials mixed in the glass, thus being prodeced of grass products. Defects are mainly foreign body defects such as sand, knot and wave reinforcement. What may directly affect the quality of glass are the wall brick and brick kiln bottom.
Q:Which one is better, fire-resistant wood or steel?
Rebar would weaken and quickly collapse in the fire, and the fire resistance of a heavy log is much better than steel. In many ways, the fire resistance of a large log is equal to reinforced concrete. The heat transfer capacity of wood is 400 times smaller than steel, 8.5 times smaller than concrete. When burning, wood will form a layer of carbon in the surface, and as long as the cross-section of the timber is over a certain size, this layer of carbon it will become an excellent flame retardant layer to protect the interior of the wood from burning. So the United States and Japan and other European countries allow and encourage the use of wood structure with a large section (beam column of 8 inches or more) to construct public buildings without the need for fire treatment applied to wood surface. I hope my answer will be helpful to you.
Q:How many types of special refractories are there?
Metal ceramics, high temperature coatings, high temperature fiber and other reinforced materials
Q:How to distinguish between class A fire resistant door and class B fire resistant door from appearance ? What are the differences between the two refractories? Thank you !
First, the materials are the same. But the thickness of grade A and grade B fire doors is different juding from their appearances. Grade A :50. Grade B:45. Added question: Do you refer to steel fire door?
Q:What are the standards of refractory concrete ?
The special concrete compound by uitable binding materials, refractory aggregates, admixtures and water at a certain ratio. It can maintain the desired mechanical property at high temperature of above 900 ℃ for a long time. The property depends on the material and matching of all the aggregates, admixtures and binding materials. Its material, composition and ingredients are similar to these of refractory castable. Refractory aggregate can be dry slag, broken refractory bricks, basalt, bauxite, magnesite, etc. According to the binding material, it can be divided into Portland cement refractory concrete, aluminate cement refractory concrete, sodium silicate refractory concrete, phosphate refractory concrete, magnesia refractory concrete, etc. (8) The particle material and powder material in refractory concrete are called aggregate and admixture respectively. The mixture of concrete can be moulded by casting, vibrating or ramming. And proper measures to promote their hardening can be used in accordance with the hardening characteristics of the binding materials (such as air hardening, water hydraulicity, thermal hardness, etc.). It is mainly used to build the monolithic lining of industrial furnace and procast blocks. Of all the concrete, the ones used for under 900 ℃ is called heat-resistant concrete, and they are used for the foundation and chimneys, etc. of industrial furnaces and thermal equipment.
Q:How to distinguish the fire resistant level of the rubber and plastic thermal insulation material?
Level A of non-combustible insulation materials are: W W inorganic active wall insulation materials, cement foam insulation board, glass beads of insulation mortar, rock wool board, glass wool board and foam ceramics, ect. Th e level A is non-combustible material, characterized with low density, low thermal conductivity, high bearing capacity, convenient construction, economy and durablity, and widely used as the thermal insulation materials in hot pipes, thermal equipment and other pipe-line equipment and industrial architectures, and as the thermal insulation, heat insulation and sound-absorbing materials in industrial and civil building envelope. Because of its good thermal stability, it is more used as fire-resistant protective coating material of steel structure.
Q:What is shapeless refractory with high performance?
The popular ones are: Non-cement fine powder bonded castable is a functional refractory castable with nano material introduced.
