Magnesia is divided into sintered magnesia, light burned magnesia, fused magnesia three categories.Magnesia refractory material is one of the most important raw materials, aluminum used in the manufacture of all kinds of magnesite brick, magnesite brick, ramming material, repairing, etc.Contain a more impurities, are used to construct steel furnace bottom, etc.Sand in the main ingredients for magnesium oxide, impurities such as CaO, SiO2, Fe2O3, magnesium oxide as basic oxide, melting point is 2800 degrees, after the high temperature heating into stable cubic crystal, commonly known as periclase.By magnesium hydroxide by high temperature calcination, hydration resistance ability.Sintered magnesia is mainly composed of magnesite, magnesite or water from the water extract of magnesium hydroxide by high temperature calcination.Hydration resistance ability.Magnesite calcination under 700-950 ℃ is escaping CO2, magnesite as soft porous loose material, cannot be used for refractory material;Magnesite through 1550-1600 ℃ calcination so-called burned magnesia said sintered magnesite.Light burning magnesium powder is bending, compression, high strength, hard, gelled material, widely used in national defense, medicine, chemical industry, paper making, shipbuilding and other industries.In the building materials industry produce tire sub board, particle board, heat preservation columns, railing, artificial marble, asbestos tile, ordinary tiles, wall panel, laying on the ground.With the progress of science and technology, light burning magnesium powder application more widely, civil products, light and heavy machinery packing boxes, packaging can do sill, high-temperature refractory material, also can make beautiful luster strong furniture, in the machinery industry to do model.

Q:What are the materials of insulation firebricks?
The raw materials of firebricks, firebricks have various raw materials, and the composition of which can be divided into six categories: soil, stone, sand, mineral, powder and others. One of the raw materials, soil: bauxite, kaoline, clay, diatomite Another raw material, stone: fluorite, kyanite, andalusite, forsterite, vermiculite, mullite, pyrophyllite, chlorite, dolomite, sillimanite, magnesia-alumina spinel, and silica Another raw material, sand: clay sand, zircon sand, quartz sand, and magnesite Another raw materials, mineral: chromium mineral Another raw material, powder: aluminum powder, micro-silica powder, and silicon powder Another raw materials, others: asphalt, graphite, phenolic resin, perlite, cenosphere, sialon, corundum, silicon sulfate, silicon carbide, sodium silicate, silica sol, boron carbide, calcium aluminate cement, nitride material, haydite, aluminum oxide, alumina sol and zirconia, etc.
Q:What are the materials of class A fire resistant window?
The filling materials of steel, wood frame should be non-combustible materials. Fireproof glass can use qualified products that do not affect the fire window fire resistance performance, whose light transmittance should be no less than 75% that of the commom sheet glass with the same layers. Sealing materials between the frame and fireproof glass should be nonflammable materials. Hardware fittings should be fixed supporting products that pass the test.
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:Who knows the roofing fireproofing and waterproof material?
If you should do home water proofing, I recommend the acrylate waterproof coating with high elasticity of Qinglong waterproof, because it has good aging resistance, extensibility, elasticity, binding property and film-forming property; waterproof layer is a closed system, the overall waterproof effects are very good, especially for the construction of heterotypic structure base and roofing, walls, toilet and bathroom, basement and other buildings waterproof and anti-seepage engineering in the conditions of non-permanent immersion;
Q:What are the applications of refractory busway?
Is an ieal power supply equipment for modern large and medium-sized enterprises, high buildings, the introduced projects, experimental base and other places.
Q:How to use fireclay?
Actually, fire clay is not strong. Fireclay are all clinkers with no strength, also known as "blade mud". It is used as the filler with a thickness of not more than 3mm. Therefore, it can not be used for thermal insulation inside the furnace. Inner thermal insulation of the civil boiler can use "alumina cement", also known as refractory cement.
Q:What are the filling refractories in door leaf of class A fire resistant door?
Perlite!
Q:Fire rating of decoration materials
All light steel keel gypsum board is considered level A; if the wood finishes up to B2 grade fire rating depends on the proportion of the use of wood veneer and the proportion of this wood veneer fire grade, if the proportion of wood veneer is small,it can be considered level A
Q:Firing high temperature kiln of refractory and internal temperature being as high as 1600 ℃, metal heat exchanger can't use, how to do?
Directly using silicon molybdenum kiln, the temperature is better. Now using the electricity is cheaper than the price of other fuels.
Q:what is steel fire door made of ?
1. fire resistance steel door has steel made door frames, door leaf framework and door panels. if the door leaf is filled with nontoxic fire insulation material, added with fireproof hardware accessories, which consists of a door that is fire resistance. This is a steel door.
