Q:What are the construction measures of refractory material in winter? Please descriptive briefly.
Binding agent should be attaced great importance to when construction is conducted in winter. Generally if the bingding agent is water or cement, antifreezing measures should be taken.
Q:Who knows about the fire endurance of grade C fire doors?
The fire endurance of grade C fire doors is no less than 0.5 hours. As the key role of family fireproofing, fire doors is particularly important. It can be classified according to the fire endurance and thermal insulation performance: The fire endurance of grade A fire doors is not less than 1.5 hours; that of grade B fire doors is not less than 1.0 hours; and that of grade C fire doors is not less than 0.5 hours. We can choose in accordance with different needs, but commonly used fire doors are grade A and B fire doors now.
Q:Do you know where I can buy refractories?
Refractories are sold in following companies : Address of Huadu Refractories Co., Ltd. : NO.11 Huanjin Road, Fuyang, Hangzhou Address of Zhenxing Special Fire-Proof Material Co., Ltd. : No. 54 Pingjing Road, Yuhang District, Hangzhou Address of Zhongnai Refractories Co., Ltd.: No. 345 Fuyang, Hangzhou, Zhejiang Province
Q:What are the filling refractories in door leaf of class A fire resistant door?
Magnesium chloride, magnesium oxide, perlite and other mixtures.
Q:Who knows the model of fireproofing materials?
Inorganic binder: it mainly includes sodium silicate, gypsum, phosphate, cement,etc; refractory mineral filler: aluminium oxide, asbestos powder, calcium carbonate, perlite, cornstarch,etc; nonflammable organic resin: it mainly includes polyvinyl chloride, perchloro-ethylene, chlorinated rubber, neoprene latex, epoxy resin, phenol resin,etc. Nonflammable fireproof addictive: it mainly includes phosphorus, halogens, nitrogen organic compounds (chlorinated paraffins, TBP ( tributyl phosphate ), decabromodiphenyl ether), and borate series (boric acid, zinc borate, aluminium borate), antimony series, aluminium series, zirconium series and other inorganic compounds.
Q:What is neutral refractory? Can refractory suppliers tell the main components of it?

Q:What are the common refractory insulation cotton material?
I know less about this, I hope the following will help: Fire resistant thermal insulation material mainly refers to inorganic thermal insulation material and compround thermal insulation material. According to the shape can be divided into: Fibrous finishes, slag wool, rock wool, glass wool, aluminum silicate cotton. ceramic fiber, micro pile of diatomite, calcium silicate, expanded perlite, expanded vermiculite, aerated concrete etc., foam like bubble glass, volcanic ash glass, foam clay, foaming concrete, paste powder polystyrene particles insulation slurry
Q:What occupational hazards should be detected in glass ceramic and refractories industry?
Q:Who can introduce the difference between galvanized fireproof coatings and steel structure fireproof materials?
Steel structure with heat galvanization has a process requirement, which is to spray fireproof coatings. Fireproof coatings have different functions and purposes from galvanized process. When the steel surface derusted, it generally needs to brush rich-zinc primer before spraying fireproof coating. Fireproof coating plan itself includes anticorrosion plan, and fireproof coating is just a layer of coating plans, which is an intermediate layer in general. Fireproof coating plan generally includes primer, fireproof coating and finishing paint. Some fireproof coatings can be directly painted on the bare steel elements without primer and finishing paint.
Q:What is the difference in the nature between the refractory material and thermal insulation material
thermal insulation material is used to thermal insulation and the transfer of heat insulation. refractory material is defined as greater than 1580 ° non-metallic materials, such as calcium silicate board. its using temperature can reach to 1100 degrees, and some can also be used at high temperatures, and all high-temperature industrial can't be oprated without it, and the using temperature of polycrystalline alumina fibers can reach to 1800 degrees
