Q: What are some of the new refractories and what are their characteristics?
Refractory common AZS refractories are often used brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, aluminum oxide, beryllium oxide and other refractory materials, Magnesium Oxide
Q: Why the refractories should be waterproof and wetproof
It is necessary to like magnesium carbon, waterproof and wetproof is more important. There is a variety of refractory materials, in general, basic is defective, and wherein the binder and additives water will lose their effect, the relationship is not very high aluminum large amount of water determines how much of the performance after the hydration will affect the strength and high temperature performance ;; hydration & quot, just need a little package like magnesium and calcium-based product itself readily react with water to calcium oxide, magnesium, chromium is not all the material goods have waterproof ordinary bulk materials need to add water before use
Q: Who knows what is the external wall thermal insulation materials for level A fireproofing?
external wall thermal insulation materials level A fireproofing: Incombustible building material is a material that does not occur any burning. Class A1: Monomer inorganic non-combustible. Noncombustible means no open fire. Class A2: Non-flammable organic compound is namely composite materials and non-flammable, the amount of smoke must be qualified. Class 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. Class 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.
Q: What is the use of refractory?
It is equivalent to a protective layer. It can be used to protect structural materials from being direcctly attecked by high tempereture or internal gases. General structural materials are steel, so the main function is resistant to fire and high temperature. In literal meaning, refractory is a fireproof material. Steel is easily deformed and wore. Structural materials can not directly touched with solid and liquid. Refractory materials are generally used as a protective lining of structural material, so it is necessary to be protected.
Q: What is the classification standard of fireproofing material levels?
Standard: Class A: Incombustible building material, almost without burning. class A1: Non-combustible, no open flame,class A2: Non-combustible,it needs to measure smoke and be qualified. Class B1: Nonflammable building material: Nonflammable materials have good flame resistance function. when it contacts open fire or is under high temperature, it's difficult to burn and be spreading rapidly, and will stop burn after removing the combustion?source. Class B2: Combustible?building?materials: Combustible materials have good flame resistance function. when it contacts open fire or is put in the air at high temperature, it will immediately burst into flames, and easily result in the spreading of fire, such as wooden column, timber roof truss, timber beam, wooden stairs, etc. Class B3: Inflammability building materials, without any flame resisting effects, easy to burn, and has large danger of fire disaster.
Q: How to measure the influence of high-temperature performance of the products refractory in the formation of the liquid phase.
Seeing whether it can affect the usage of the refractory material, and seeing to reduce the impurity, what's the condition of temperature of the liquid phase. Practically, whether it has any difference if you can improve, load under load and creep and reduce the impurity content. In the refractories, producing liquid are the influence of impurities, high temperature resistant strength, compared the use of the refractory material temperature: testing compressive strength after burn. If there are any impact: knowing the main crystal phase of matrix composition and content, improving the content of the main crystalline phase can improve the high temperature performance of refractory materials.
Q: The performance of refractory material
As for easticity modulus, you can serach for information on the Internet or specialized books.
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: What kinds of refractory materials that can resist 3,000 Celsius degree?
I think that graphite is the only one.
Q: Is there a worker in (Jigang refractory plant)?
Units in this way, it is necessary to slowly boil it, wages will come up. You are a labor worker, and can not share with the stock system staff. There's a difference between salary and vacation.
