Q:What is the role of adding chromium oxide green in unshaped refractory materials
Generally, less is added in corundum or corundum spinel refractory material, but it can significantly improve the material performance such as high temperature strength, erosion resistance, thermal and shock stability, etc.
Q:What are the best refractory materials in 2,400 Celsius degree?
You can try zircon sand which has a melting point of 2430.
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.
Q:Why can aluminium hydroxide not be used to make refractory material?
Hope my answer is helpful to you. It decomposes and produces aluminium oxide and water after heating, chemical equation for the reaction is: 2Al(OH)3=△=Al2O3+3H2O. Aluminium hydroxide can't be directly used to make refractory material because aluminium hydroxide is not stable.
Q:Current development status of qualitative refractory materials.
Q:How to choose thermal insulation materials for flood heating?
1, Select the appropriate floor material suitable for radiant floor heating. The floor radiant heating system mainly transfer heat through the ground concrete and the ground material to the room. Therefore in the heating season the ground material will always be heated during heating season. Therefore, it is better to choose stone materials and compround floor plate insensitive to tenmperature change with good heat dissipation and functions. Currently, wood floor is not suitable for the ground radiant heating system. 2, choose the pipe with anti permeability performance. Plastic floor heating pipe itself has a certain air permeability, if oxygen penetrates in it is prone to oxygen erosion and system's mental device will be eroded, resulting in the risk of leakage. Therefore in order to ensure the reliable operation of the heating system, the selected pipe must have anti oxygen permeation performance, and meet the standard stipulated by the DIN4726 oxygen permeation quantity: and be less than 0.1mg\L.d at 40 C.
Q:What are the qualifications of refractory industry?
Special qualification issued by Fire department
Q:which is better as household fireproof material ?
the thickness recommended is 1mm or more # 304 stainless steel plate, refractory corrosion-resistant, easy to clean. It now appears that among the most common fireproof material, asbestos is the best. But the asbestos harmful effect is also great, especially for lung damage. Now on the market, the polyurethane, polystyrene, rock wool glass wool, phephenolic aldehyde fireproofingthermal insulation board. But now the phenolic aldehyde fireproofing thermal insulation board has superior performance! phenolic aldehyde containing only carbon, hydrogen and oxygen atoms, when subjected to pyrolysis, except small amounts of CO gas, the other will not produce toxic gases, maximum smoke density is 5.0%.
Q:What's the maximum temperature that the refractory ceramic fiber cloth can endure?
Ceramic fiber cloth is high temperature resistant and its continous use temperature can be up to 1000℃. It has high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment; and it is easy to install.
Q:Which one is the best refractory material?
Resin bonded refractory is mainly abot aluminum magnesium carbon, and carbonaceous etc. Thermoplastic resins need to add the coagulant (Uto), ageing mixture for a period of time, so the production cycle is long. Hot hard resin is relatively not so complex, but it’s not as good as thermoplastic resins in thermoplastic binding.
