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:How long is the fire-resistant time of fireproof wooden door?
fire endurance class A (1.5 hours), class B (1.0 hours), class C (0.5 hours).
Q:Is it normal for caable fire resistant material to catch on fire?
Abnormal; aging is certainly one of the cause of the fire. That is caused only because of poor insulation and aging caused by short circuit, but a more important reason is configuration of air switch does not meet the requirements. If the capacity of air switch equals that of the cable, trip will happen at the moment when current is overloaded, not causing a short circuit or over current fire.
Q:What is the magnesium carbon refractory?
The composition of refractory brick raw material There are many types of refractory brick raw materials, mainly divided into six categories: Soil, stone, sand, mineral, power and others. One of the original material, soil: Aluminum, kaolin, clay, diatomaceous earth The second raw material, Stone: fluorite, kyanite, andalusite, forsterite, vermiculite, mullite, pyrophyllite, chlorite, dolomite, sillimanite, magnesia-alumina spinel, silica The third kind of raw material, sand: Pottery, zircon sand, quartz sand, magnesite The fourth kind of raw material, ore: Chrome ore The fifth kind of raw material, powder: Aluminum powder, silica powder, silicon powder The sixth kind of raw material of refractory brick, others: Asphalt, graphite, phenolic resins, perlite, cenosphere, sialon, corundum, silicon sulfate, silicon carbide, sodium silicate, silica solution, boron carbide, calcium aluminate cement, nitride material, shale ceramisite, alumina, alumina sol and zirconia, etc.
Q:How to hang the suspended brick in the refractory masonry?
First you can weld the metal fastener of the suspended brick and then hang up the brick.
Q:What kinds of refractory materials that uses a-Al2o3 powder? What are the purpose of it?
04La-Al2O3 powder is a alumina powder whose raw material is industrial aluminum oxide which has been calcined at high temperature. It is a good polishes for ceramics and jade, meanwhile, it is also an important raw material for high-end refractory materials. The technical indicators parameters A1023 mark A1535 chemical composition AL2O3≥ 99.92 3%, ≥ 3.10FE203≤ 0.799 Refractory calcined alumina powder (a-Al2O3) 1.2 true density (g & # 47, by fully ground powder made of different fineness .O.10 0.07 0.04NA2O≤ 0.93a-Al2O3 (%) ≥ 95 95 primary crystallization average grain (um) 2 ~ 3 3 ~ 5 average particle size (um) 40 ~ 602.6SIO2≤ 0.1 0.15B2O3≤ - 0, glass, engineering ceramics typical use electronic ceramic insulating ceramic refractory ceramic wear 3
Q:Which one is the best refractory material?
o make it simple, you can kindle it, and observe the burning time. If there is a professional need to be accurate, then you can send it to the professional testing company. As far as I know, the Kebiao Company over the victory bridge, Qingdao can offer professional test. I hope my answer can help you, thank you, hope to be adopted.
Q:Who knows about roof fireproofing materials?
Roof water proofing materials: synthetic polymer waterproof rolls, high polymer modified asphalt waterproof coiled material, sheet metal, synthetic polymer waterproof coating, one-component water curing polyurethane waterproof coating, penetration crystalline waterproof coating. Secondly, we have to choose materials that are suitable for roof water proofing. The right waterproof materials have better waterproof performance, TS-3B one-component water curing polyurethane waterproof coating is very suitable and the performance is good. Since traditional roof waterproofing materials have requirements on the moisture content of the formation level which should be less than 9%. It is really important to choose which materials to repair leaking roofs. Kitchens and toilets are moisture, the formation levels of buildings are hard to satisfy requirements, thus, waterproof layer and formation level are easily get separated and are ineffective in waterproofing.
Q:Who knows the fire resistant level of the rock wool color plate?
Hello; Same with other unprotected steel, the fire endurance of the color steel plate is generally 15 minutes. It is not a fireproofing material, let alone fire resistant level. If the color steel plate has sprayed fire retardant coating and the thermal insulation filling material in the core is rock wool fiber, it can achieve A level fireproofing requirements. The color steel plate refers to the painted steel plate, which is a steel plate with organic coating. The color steel board is divided into the single plate, color steel composite board, floor support board, ect. It is widely used in large public buildings, public plants, portable dwelling, and integrated housing walls and roofings. I hope that will help you.
Q:Who knows what is the requirement for fireproofing of interior decoration materials ?
In addition to the underground building, combustion performance level of interior decoration materials inside windowless room , in addition to a class, should advance 1 level based on the original provisions . Library, archives and rooms storing artifacts, ceilings, walls should use class A decoration materials, and the ground should use decoration materials no lower than class B. When high temperature parts of lighting and lighting lamps and lanterns are close to non - grade A decoration materials should be taken, fire prevention measures such as thermal insulation and heat dissipation must be taken. Combustion performance level of materials used for lighting should be no lower than B. Kitchen ceiling, wall and floor should used class a decoration materials.
Q:What refractories are accessible with ease in daily life?
Basically there have all materials. But it depends on your needs.
