Q: Who knows the classifications of magnesia refractory?
Magnesia chrome series products: The main ingredients of magnesium chromium series are MgO and Cr2O3. Periclase is the first phase and magnesia-chrome spinel is the second phase. Products belonging to this series are magnesium chrome brick and chrome magnesia brick. The main ingredients of magnesium aluminum series are MgO and Al203. As they generate MgO and Al203, all magnesium chromium series products contain magnesia material. magnesium calcium series products The main components are MgO and CaO. They have high melting points, which are important magnesia materials. 5, magnesium silicon series products: The main component of magnesite series is SiO2, when the C / S<5, SiO2 and MgO generate MgO.Al2O3 (forsterite). From the perspective of microscopic mineral, main products of pure aluminum series include magnesium aluminum brick, periclase spinel brick, corundum spinel brick and aluminum-spinel castable in unshaped materials. I hope this answer can help you.
Q: What's the fire endurance of hollow brick?
Light weight, high strength, thermal insulation, sound insulation and noise reduction. environmental protection, no pollution, the ideal filling material of frame structure building, Disadvantages:: poor seismic performance, fire reistance being less than 1000 ℃.
Q: Is there requirement for radiation indicator in refractory?
All refractories have no radiated harm to environment, so there is no requirement. From the elemental analysis, magnesite. I do not know it is helpful to you. But for refractory rwa material, any chemical element is radiated, including silicon?dioxide; If they are radioactive. From the use analysis, such as bauxite, do not have use value.
Q: how to divided the external wall thermal insulation materials fire rating
Level A: Incombustible building material: It is a kind of material that almost does not occur burning. Level B1: Nonflammable building material: Non-flame material has good flame resistance. It is difficult to fire under the condition of open fire in the air or high temperature, and it is not easy to quickly spread, and when the combustion?source is removed, the combustion will stop immediately. Level B2: Combustible?building?materials: Flame material has a good flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as wooden column, timber roof truss, timber beam and wooden stairs. Level B3: Combustible?building?materials: It has no any flame resisting effects, and is easy to burn, so the fire risk is high.
Q: Why do magnesium oxide refractory bricks can be made into refractories?
The substance used in refractories must have the following characteristics and properties: 1, High stability: Anti-oxidation, anti-reduction and thermal decomposition; 2, High melting point of 2800 degree; 3, Low price. The magnesium oxide refractories have all these three characteristics and properties, particularlly in the aspects of melting point and stability .
Q: What refractories can withstand high temperature above 2100 degrees?
You can refer to advices from the first one coupled with the second one.
Q: What's the material of fireproof and wear-resisting floor?
1. It is the kind of special concrete floor, and its production process is the same with that of the common concrete floor, but it uses different material which needs to be the pebbles and sand after processing with marbles and dolomite. 2. Fireproof floor is a kind of decorative material which is laid on the ground of the factory or large areas of floors. It does not support combustion or it is composed of flame retardant materials. Fireproof floor has two categories. One is composed of aggregate wear-resistant material which is solid particulate matter. Its construction method is to evenly spread aggregate wear-resistant particles on the surface layer of the concrete when the floor is just pouring concrete and solidified, and then a firm flame retardant layer will be formed on the surface layer. This is the the so-called carborundum wear-resisting floor. But this kind of material has many limitations and can only be used on the surface of the just poured concrete. In addition, it is easy to fade in color and not beautiful in appearance. So this is not fireproof floor in the strict sense. Here we focus on a new liquid coating fire protection floor, which is environment friendly, widely used and beautiful in appearance. 3. Wear-resistant floor has the characteristics of pressure resistance, strong wear resistance,oil resistance, and anti-infiltration. It is also dust-free and easy to clean. After entering the initial setting of concrete, construction can be started immediately. Construction period is usually longer, but better using effect will arise.
Q: how long is the fire endurance of plasterboard?
Gypsum board is flame retardant materials, combustion performance rating B1, but when mounted on a steel joist, it can be seen as rating A(non-combustible material) . So it is fine to use as a ceiling. You can randomly choose several samples to run some tests at the quality inspection insititute and the quality of these samples are subject to the testing results.
Q: What kinds of refractory materials that can resist 3,000 Celsius degree?
I think that graphite is the only one.
