Q:Which company needs the new refractories?
The power plants are mainly used in steel plant, lime kiln, coking plants, boilers, etc. I will try my best to answer what I can. There are too many glassworks. You can tell me more anout what you need. As long as there is a large kiln business, the refractories and aluminum manufacturer are needed.
Q:What kinds of fireproof materials does the safe use?
Copper is one of the most widely used material in safe, for its good mechanical performance, corrosion resistance and processibility and it has beautiful color. Especially handles, locks and other decorations forged of copper are smooth, pore-free, also they have good density, and no blisters. They are solid and rust-proof, which can get gilded with 24K gold or gulch-gold and have other surface treatments. A lot of colors have been added to people's home for the copper's magnificence and nobleness.
Q:The development prospect of fire-resistant material
Exported bulk material amounts to exported raw material/ To protect domestic resources, many countries have set linitations on the magnesium content in shapeless refractory material and lisences.
Q:It the Special Fire-Proof Material belonged to ceramics? Is there a national standard of the Special Fire-Proof Material?
The fiber and reinforcing material of the metal ceramic is also belonged to the Special Fire-Proof Material. ~~~~GB is too much trouble, GB online should ~~~ Lei Bao Refractories for you. The high temperature inorganic coating. 5. The refractory compound. 3. The high melting point oxide. You can search it on the internet according to the classification~~~~ The special refractories can be divided into five categories: 1. metal ceramic
Q:How long is the duration of fire resistance of hollow glass magnesium board
Hollow glass magnesium board features fire prevention, waterproof, tasteless, non-toxic, not frozen, not rot, not crack, unchanged, non burning, high strength and light weight, convenient construction, long service life and so on, and it has more characteristics among products of the same kind nationwide. Its fire resistance limit is 0.65℃.
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:Is fireclay poisonous?
Refractory materials are typically oxides, alumina, magnesium oxide and aluminate cement and etc, which are non-toxic.
Q:Who knows what kind of fire prevention materials are there?
Plant use general steel structure more often without too much modification. If there is a need for modification, boards which can meet the requirements of fireproof are suitable, such as gypsum boards and aluminium sheets. As for coating, it is favorable to use coating that has fine powder, high density and better sealing. Hardening agent mainly depends on the specific requirements.
Q:Which refractory is suitable for the tunnel kiln?
The refractories produced by the following ten manufacturers are relatively good. They are all being the top ten brands! 1. king coconut (Chinese well-known trademarks, famous brand, the nation's largest manufacturer of wood panels, large building materials chain enterprises, Hangzhou king coconut Holding Group Co., Ltd.) 2. Fuxiang (founded in 1998, the leading professional sheet production outstanding enterprises, Fuxiang Industrial Co., Ltd.) 3. Bunny (China famous brand, China Top brand, plywood industry iconic brand, large listed companies, high-tech enterprises, Edward Bunny decoration materials Co., Ltd. 4. new Millennium boat ( Chinese well-known trademarks, famous trademarks in Zhejiang, Zhejiang famous brand, well-known trademarks in Hangzhou, Zhejiang Province key forestry enterprises, the Millennium boat Group Hangzhou Huahai Wood Industry Co., Ltd.) 5. Jin Luli (China famous brand, Chinese brand-name products, Shandong Province, to wood-based panels and steel-based enterprises, hundred private enterprises in Shandong Province, Luli Group Co., Ltd.) 6. Albert (professional fire protection board development / production and marketing of the modern manufacturer, the introduction of advanced production technology industry HPL) 7. desert oasis (China famous brand lumber, China's top ten brands plate, sheet famous Chinese brand, oasis Wood) 8. Peng Che-hung (professional fire protection board development / production and marketing of the modern manufacturer, the introduction of advanced production technology industry HPL ) 9. Worldwide (professional magnesium fire plate glass production and sales of integrated large-scale well-known enterprises, famous brands Firewood industry) 10. Mogan (national key high-tech enterprises, China's largest and most influential environment-friendly decorative materials production one of the enterprises, Zhejiang Hua Yunfeng new material Co., Ltd.)
Q:What kind of refractory materials should be used for the intermediate frequency furnace to smelt manganese?
You mean furnace lining or ladle lining? Generally magnesia is used as furnace lining, but heat preservation should be practiced when shut down, or brasque would crack. Surly you can employ existing furnace lining which is sold in Tianjin, a little bit expensive, the average lining could be used for 300 furnaces. The furnaces made by magnesia myself break down after 40 furnace were finished. What I referred is a furnace weighing 2 tons, as for a bigger furnace, the existing brasque would be OK. What is the difference between furnace lining and ladle lining? Can you give me more detail about the materials of making a furnace weighing 2 ton? Why others can burn 80-90 furnace with 0.7-ton furnace; over 200 furnaces with 2 ton? What are these ingredients? What I know is just magnesia, magnesium borate, and together with boric acid, they also have many types, which one should I use? Thank you!
