- Q: What kind of fireproof material is used for steel structure?
- Steel is a building material that does not burn, it is shock resistant and anti-bending. In practice, Steel can increase load capacity of the building, but also add asthetic beauty to the architecture design; Unlike concrete, it can bend and stretch. Therefore, the steel construction industry has been favored, such as one-story or multi-story buildings, skyscrapers, factories, warehouses, waiting rooms and waiting hall, which is the common use of steel. However, the steel as building materials has unavoidable defects in fire prevention, its mechanical properties such as yield point, tensile strength and modulus of elasticity, decrease abruptly due to temperature rise.
- Q: What is the function of refractory in ceramics?
- In addition, the quality of refractory determines the finish and color of ceramic glaze.
- 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: What's the heat conductivity coefficient of fire-resistant material?
- 5～5 (Unit: W·m-1·K-1). The symbols are λ or K. Thermal conductivity and material properties Thermal insulation material generally is 0, and is related to organizational structure and working temperature. Thermal conductivity of the material refers to the heat transferred from from one plane to another plane in 1 seconds. Generally the thermal conductivity of fire-resistant material is 1. The larger the value is, the stronger the thermal conduction performance is. If the temperature of two planses differes for 1K, then the thermal conductivity is 03~1. The plane cover 1square meter.
- Q: What is the material composition of the new fire-resistant coating?
- New fire?retardant?coating materials are produced by non-toxic expanding materials and special process, with no pollution. Use natural bite when installing, without using the formaldehyde and other toxic glue. It consists of a variety of organic matters, so it adapts to the natural environment, with long time of fire-resistant; The fire-resistant time for new fire retardant module is up to 4 hours or more, three hours more than the standard prescribed by the state. It is composed by the specially formulated materials, with no flying smoke, good heat insulation effect, fast heat dissipation, scientific and rational design, easy using and no falling off and long period of effective.
- Q: Why should graphitic refractory materials be used now that graphite can burn?
- Materials for refractory must have the following characteristics and properties: 1, high stability: Anti-oxidation, anti-reduction, thermal decomposition; 2, high melting point : 2800℃; 3, low price. Graphite has all three characteristics and properties, especially melting point and stability.
- Q: Does anyone know what is the use of waste refractory materials?
- 1.Waste refractory bricks can be reused to make the refractory bricks after being crushed by crusher, but the price is not very high. The purchasing price of refractory plant is ?60/ton. Because the refractory material has been calcinated for two times, it becomes easier to make bricks expansion coefficient with waste refractory bricks, but too much is inadvisable. If too much, the refractory materials would have a bad combination, which will give rise to loose bricks and incomplete corners. Nowadays, ordinary refractory plants would purchase waste refractory bricks to produce bricks, but better plants wouldn’t do this.
- Q: What are the requirements when producing fireproof materials by kaolin?
- Kaolin refractories in fact play a role in two aspects, one is to improve the refractoriness, the second is to improve plasticity of the the refractory . Aluminum content the higher the better, of course, but kaolin is not the only material to improve the content of aluminum, using materials that contain higher content of aluminum such as the bauxite chamotte. So the content of kaolin aluminum does not have to be too high. over 38% is fine. viscosity is important and strong viscidityis better without having to add bentonite. Refractoriness above 1400 degrees is enough.
- Q: What are the commonly used admixture for alumina-magnesia refractory? What are the impacts on its performance?
- 2, form Mg-SiO2 coagulation and combination, CA cement bond? Bricks can generally be made by combing with phenolic resin, castable use 1, combined with silicon powder; 3, can also combined with brine MgCl is binding agent
- Q: What are the materials used in refractory material processing?
- AZS special refractory 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, alumina, Magnesium Oxide, beryllium and other refractory materials. Often used insulation refractories are diatomite products, asbestos products, insulation panels and so on. Unshaped refractory materials commonly used are fettling, refractory ramming material, refractory castable, refractory plastic material, refractory clay, refractory gunning, refractory cast material, fireproof coating, lightweight castable, mud etc..
