Q: What are the materials of white firebricks?
White refractory materials are generally divided into two types, namely, unshaped refractory materials and shaped refractory materials. Unshaped refractory materials, also called castables, is a mix of powdery particles of many aggregates and one or multiple adhesives. They must be stirred well with one or multiple liquids when in use, which has a strong liquidity. Unshaped refractory materials generally refers to firebricks. They have standard rules about their shapes and can also be processed temporarily as needed.
Q: What are included in wall fireproofing material?
External wall thermal insulation materials are divided into A and B according to combustion level. Grade A is incombustible material, while grade B is combustible material. A few years ago, fires in CCTV building and Shenyang hotel resulted from grade B material. Currently grade A is usually used, and some are even cheaper than the grade B material. Grade A is roughly divided into insulation mortar, phenolic board, rock wool board, foam cement board, etc. Insulation mortar is quite good. It is easy and convenient to construct, has low cost, but the production is too simple and it is easy to fake. It is recommend to find a large manufacturer with complete formalities, such as provincial records of production, provincial records of use, city records, type test report at or above the provincial level, national fireproof report and design drawing collection of department of construction. Lack of any is unsafe. It is recommended to use mortar from Hebei Qizheng Haocheng New Building Material Co., Ltd. It is absolutely large manufacturer. MPC thermal mortar produced by it is recommend product of Department of Construction in Hebei Province!
Q: I want to know what is the slim in the refractory bricks
Where are you from, I can introduce to you
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 material is used for making refractory stone bowl?
Good refractory stone pot is carved from high-quality natural refractory stone in a professional way. But many are also made of synthetic materials, the price is lower, too.
Q: What is the the best matching ratio of refractory cement?
The best matching ratio of refractory cement is 30%. Refractory cement is also known as aluminate cement. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. Refractory cement is also known as aluminate cement. Aluminate cement is often yellow or brown or gray. The main mineral of aluminate cement is mono calcium aluminate (CaO · Al2O3, abbreviated CA) and other aluminates, and a small amount of dicalcium silicate (2CaO · SiO2), etc. It is a special cement. I hope my answer will be helpful to you.
Q: What is refractory cement?
Ordinary portland cement is common cement with relatively high early strength, while refractory cement is low in this regard. Refractory cement is a characteristic cement which can only be used in special projects, not suitable for general engineering. And in the winter, it is not suitable for construction use.
Q: What are the differences of ceramics and refractories? Is the ceramics belonging to refractories?
No In the high school chemistry, the former is talking about the traditional inorganic material, the latter is belonged to the new materials.
Q: Fefractory of aluminium oxide.
Do you mean the alumina hollow ball brick? We can exchange private messages in specific.
Q: Does the aluminum silicate thermal insulation material fireproof?
Yes, because of its low heat conductivity coefficient, and good thermal insulation, it can be setting fire.
