Q: what's the application of fireproofing abs materials?: ABS is acronym of Acrylonitrile Butadiene Styrene )it is a kind of thermoplastic high polymer material with properities of high strength, good toughness, easy processing and molding. it has high strength, corrosion resistance, high temperature resistant, so it's often used in the plastic shell manufacture of instruments.

Q: Who knows the setting requirements of roofing fire barrier zone?: First, the the minimum of fire barrier width is greater than 30cm, and the thickness should be same to the thickness of the insulation materials. Fire barrier zone insulation board must do the whole area sticking construction with the base wall during the construction. Fire barrier zone insulation board is required to assistant binding by anchor bolt, anchor bolt must suppress the underlying mesh. Second, Fire barrier zone should be set at the upper position of door and window openings, the distance between the low edge of isolation belt and the upper edge of the window must be less than 50cm. The thermal resistance of fire barrier zone must be half than EIFS thermal resistance in the cold northern areas, while the thermal resistance of fire barrier zone must be three times than EIFS thermal resistance in the hot summer and cold winter area. Third, When the fire barrier zone is set on the edge of the window, fire barrier zone at the upper part of the window should do flanging when sticking, flanging glass fiber mesh must exceed 10CM than firebreak insulation board. Flanging network, underlying network and surface network can not be overlapped or butted at the top of the window. I hope you can be satisfied

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 molten silicon? What refractoriness do refractories made by it have? What properties of using does it have?: Molten silicon can be called quartz glass, which shows an amorphous silicon state. It is a liquid fusion at above 1723 degree and is an ultra-cooling state at low temperatures. It is not generated in refractories, but generated in the matrix, showing liquid state at a high temperature capable of buffering the stress with somewhat binding properties. If quartz glass is used as refractory, its function are melrly these ones. (These are what I konw for reference only.)

Q: Which are fire proofing thermal insulation materials?: Grade-A fire proofing inorganic thermal insulation materials include rock wool, glass wool, vitrified micro bead, foaming cement, foaming ceramics, vacuum thermal insulation board,

Q: which kind of refractory is commonly used in the industry: Like silicon, magnesium calcium and metallurgy refractories, glass, silicon, etc., knowing the basic materials, and the businesses are not the same. I suggest that you can buy the refractory book to read.. Others include zircon, shapeless refractory material and so many other cement, such as magnesia, high alumina,ect.. Iron making is using the acidity material, continuous casting is using the clay, nonferrous metals and other types of more complex hot-press charcoal; steel making is using the alkaline, magnesium chrome, magnesium carbon, and clay,etc..

Q: How to choose construction external wall thermal insulation and fireproofing materials?: Now external wall insulation decoration one board is more popular thermal insulation material. Low-carbon energy-saving insulation decoration board combine two constructions (decoration, insulation) into one, saving nearly ten processes,and construction period. Compared with conventional thermal insulation methods, it can increase construction efficiency one time by shortening 60% of the construction period. It integrates low carbon, energy conservation, decoration, fireproof and building aesthetic effect by combining like-dissolving-like binding system installation and bump fixed system, and under long-term cooperation of air handling system and waterproof system. It has excellent outdoor weather resistance, colour?retention, alkali?resistance, water resistance, scrubbing resistance, crack resistance and temperature change resistance, wear resistance, collion resistance and the paint film is firm and durable, with strong adhesive force and mould proof effect. It can provide all-dimensional thermal insulation, decoration, low carbon and energy conservation and fire prevention for construction projects.

Q: What are the uses of refractory materials of glass furnace?: crown--high-purity silica bricks; wall--melting end 41# fused zirconia corundum bricks with no shrinkages(41% of zirconium, similarly hereinafter), cooling end 33# fused zirconia corundum bricks with no shrinkages; bottom--33# fused zirconia corundum bricks(with shrinkages); breastwork--33# fused zirconia corundum bricks(with shrinkages); port--33# fused zirconia corundum bricks(with shrinkages); regenerator chamber--the upper part is for magnesite-chrome bricks, the bottom part is for high-duty fireclay bricks; checker--the upper part is for high purity magnesia bricks, and the bottom part is for magnesite-chrome bricks; flue--clay bricks.

Q: What is refractory?: Refractory materials are widely used in metallurgy, machinery manufacturing, chemical industry, petroleum, power and other industrial fields. It is an inorganic nonmetallic material mostly used in metallurgical industry with the minimum refractoriness of 1580 ℃, able to resist high temperature without softening (annealing). It accounts for 50% to 60% in total output. Refractoriness refers to refractory's ability to resist fire.
