- Q: Is fireclay corrosive?
- No. All of the refractory materials have stable chemical properties and their usability can be guaranteed under high temperatures.
- Q: What are the refractory materials above 1000℃
- corundum would be fine
- Q: Who knows the fire rating of fire?partition with steel stud?
- 1 hour. It is in line with the fireproof test standards of national building materials . CaSo4.2H2O is molecular structural formula of gypsum which contains 20% water, crystal water and free water. When 10% water slowly evaporates on the flame surface, there is still 10% crystal water. Itself is grade A fire retardant material. It can reach up to four hours at most.
- Q: Which refractory material is better in China? Industrial furnace, mainly in non-ferrous industries, glass kiln, cement kiln business.
- Such solid nano microporous insulation material with nano inorganic refractory powder special, with a huge surface area, nano particles contact between the minimum point contact point contact thermal resistance is very large, the heat conduction effect of the material becomes very small, resulting in heat conduction coefficient of solid such nano porous insulation materials very small; nano pores formed of nanoparticles, the average size of 20 nm, and the average free path of molecular thermal motion at room temperature under static air is 60 nm, thus locking the air molecules in powder within nano pores, making the micro convection heat transfer effect between the stationary air molecules disappeared. The room temperature thermal conductivity of solid such nano microporous insulation material is lower than the static air; at high temperature, the main effect of heat transfer heat radiation, Good energy-saving insulation materials with nano microporous infrared additive special, stop at a high temperature and reflected infrared radiation, reduce the heat radiation effect to the lowest point, the radiation heat transfer coefficient of materials under high temperature is reduced to the lowest value.
- Q: Who knows about the grade C fireproof door materials?
- Wood or steel materials are usually used in them. The new national standard fire doors: According to the enacted GB12955-2008, the fire endurance of grade C fire doors is 0.5 hours and that of grade A and B are 1.5 hours and 1.0 hours respectively.
- Q: Detailed description of magnesia dolomite refractory material?
- In the cement kiln firing zone, the f-CaO in the dolomite material is easily combined with the C2S in the clinker to form C3S, so the kiln cover can be easily hung, and the kiln crust and the refractory brick are firmly combined and easy to maintain.
- Q: What kind of foundry ingot refractory materials are there? Please be more detailed.
- Classification of refractory materials used in foundry smelting process: refractory brick, siliceous brick, high alumina brick, corundum brick, magnesia brick, magnesia brick, magnesia carbon brick. Unshaped refractory materials: ramming material, castable, refractory cement, silica, magnesia, etc.
- Q: How many grades of fire?rating are there for interior decoration materials?
- It can be divided into structural material and base?material based on materials. It can also be divided into flammable, flame retardant and non-combustible materials based on fireproof types. There is no fire?rating for materials. But lengths of time of flammability limits are different.
- 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.
- Q: Classification of porosities in refractories and their effects on properties
- The first two types of stomata are commonly examined, known as apparent porosity.
