- Q: which kind of material is chosen for fireproofing window?
- (1) window frame uses steel frame or wooden frame with certain strength that can safeguard the integrity and stability of the components. (2) steel frame and mound layer can choose galvanized?steel?sheet or stainless steel plate. Its selection criteria conform to the article 5.1 in GB12955 Steel Fireproof Door General Technical Condition. (3) the selection criteria of wooden frame and mound layer should conform to the article 5.1 in GB12955 Wooden Fireproof Door General Technical Condition. (4) the inside filler material of steel, wood frame should use incombustible material. (5) fire-resistant glass can choose test approved products without affecting the fire resistance of fireproofing windows . Light transmittance of glass should not be less than 75% of same layers commom sheet glass. (6) the sealing material between the frame and the fire-resistant glass should use flame retardant materials, it can play a role of fireproofing and smoke insulation in the fire.
- Q: Does the external wall thermal insulation materials level b1 need the fire barrier zone?
- First, it is prohibited that the thermal insulation material of level B2 and below combustion performance is used in the thermal insulation project of any civil building wall, and the thermal insulation material of below level A combustion performance is used in the thermal insulation project of curtain wall civil builduing that the height is equal and greater than 24m, of non-curtain wall residential building that the height is equal and greater than 100m and of other non-curtain wall civil builduing that the height is is equal and greater than 50m. Civil builduing wall thermal insulation project must strictly enforce the "civil builduing external wall thermal insulation systems and external wall decoration fireproofing interim provisions" (referred to as "fireproofing interim provisions").
- Q: Why the refractories should be waterproof and wetproof
- It is necessary to like magnesium carbon, waterproof and wetproof is more important. There is a variety of refractory materials, in general, basic is defective, and wherein the binder and additives water will lose their effect, the relationship is not very high aluminum large amount of water determines how much of the performance after the hydration will affect the strength and high temperature performance ;; hydration & quot, just need a little package like magnesium and calcium-based product itself readily react with water to calcium oxide, magnesium, chromium is not all the material goods have waterproof ordinary bulk materials need to add water before use
- Q: What is the criterion of entry of refractory clay industry?
- Chemical composition of refractory clay is one of the important factors affecting its quality. Al2O3 is the beneficial part of refractory clay, and it mainly exists in aluminum hydroxide minerals (diaspore, boehmite, gibbsite), and it also exists in aluminosilicate minerals (kaolinite, illite montmorillonite, etc.). In general, the content of Al2O3 in soft and semi-soft clay is 30% to 45%, the hard clay is 35% to 50%, and high alumina clay 55% to 70%. Fe2O3 mainly exists in hematite, magnetite, goethite and siderite, and is the main harmful component of refractory clay. There is no evident law on the content of Fe2O3. The content in high alumina clay is 0.5% to 2.2%, hard clay is 0.5% to 2.5%, and the soft clay is generally 1.0% to 2.5%. K2O and Na2O are harmful impurities in refractory clay, which mainly exist in illite and mica and other minerals, and the content varies greatly. CaO and MgO, etc., although they are harmful impurities, but the content is generally small.
- Q: What refractories have good mechanical property resistance and heat expansion and cold contraction property?
- Explain that where you use it for and what requirements you have. Follow-up: I use it in metallurgical furnaces with the features of strong stirring and acidic residue.
- Q: What needs to be noted when choosing and using blast furnace fireproof materials? Who knows?
- there are different temperatures in various parts of the blast furnace, thus using different types of refractory.
- Q: What is the type of heat resistance property of high temperature electric furnace ?
- According to the levels of refractoriness : Common refractories: & Gt: 1580 ℃ ~ 1770 ℃ advanced refractories: 1770 ℃ ~ 2000 ℃ AAA refractories; 2000 ℃
- Q: What is the offer of fire proofing thermal insulation material?
- The following prices are from the Internet and for your reference only. Hainan fire proofing thermal insulation material ceramic fiber paper aluminum silicate fiber blanket/aluminum oxide fiber insulation cotton insulation pipe 12 yuan Hainan multicrystal mullite/calcium silicate corundum ceramic fiber loose wool short fiber fire proofing thermal insulation material non-asbestos high temperature resistant aluminum silicate fiber insulation cotton fire-resistant material ceramic fiber blanket thermal insulation blanket 28 yuan non-asbestos high temperature resistant aluminum silicate fiber ceramic fiber blanket needled felts insulation blanket fire resistant material thermal insulation cotton blanket reference price: 59 yuan
- Q: What does refractory mean?
- Acid refractory material usually refers to refractories with SiO2 content greater than 93%. Its main characteristic is that it can resist acid slag corrosion at high temperature, but it is easy to react with alkaline slag.
- Q: How many external wall thermal insulation fireproof material are there
- Class A exterior wall insulation: Rock wool, glass wool, silicate, aluminum silicate, calcium silicate, phenolic foam, foam glass
