Q: What are the fire endurance requirements of class A fire resistant door ?: The fire endurance of class A fire resistance door is 1.5H, but also depends on the product quality. The filling material of class A, B, C fire doors is the same, new fireproofing material-- perlite. The difference is their thickness. The general structure is: surface panel, fireproof?board framework (filled with perlite) fireproof?board panel. !

Q: Is fireclay poisonous?: Refractory materials are typically oxides, alumina, magnesium oxide and aluminate cement and etc, which are non-toxic.

Q: How much is the content of boron carbide in refractory material?: Boron carbide is used in refractory material. For example, generally we could add 0.2% of boron carbide into magnesia carbon bricks. It is suggested that 0.5% is enough, because it has strong effect in boosting melt. It is said that 0.5% would be alright since boron oxide after oxidation belongs to material of low melting point, so the amount should be limited within 0.5%-1%,

Q: Is there any difference between insulating bricks and refractory bricks? Are there any professional refractories factories that are reliable in the quality and quality of these irritated materials?: High alumina brick, clay brick, brick and other high-quality refractory products, widely used in metallurgy, building materials (cement and glass), non-ferrous metal smelting, petroleum, chemical, electric power, machinery manufacturing and other industries.

Q: Who knows the model of fireproofing materials?: There are many kinds of fireproofing materials, it's hard to discuss it in detail, but i can talk about the PC fireproofing material with you. There are various models of PC fireproofing materials, the materials manufacturer usually used are common materials; it's divided into the following levels according to fire?rating: UL94 VO level, UL94V1, general products can reach V2 level. hope it can help you.

Q: How long is the fire-resistant time of fireproof wooden door?: Wooden thermal insulation fireproof door using flame-retardant timber or flame-retardant timber products to make door frames, skeletons of door leaf, door panels. If the door leaf need to be filled with materials, the filling materials should be fireproof thermal insulation materials which is non-toxic and harmless to human body, and matched fireproof door composed of fireproof hardware. Use doors without age limits.

Q: What are fire?ratings of wall thermal insulation material?: 1.thermal insulation material with grade A combustion performance: YT inorganic active insulation material for wall thermal,rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2.thermal insulation material with grade B combustion performance: Extruded polystyrene board(XPS)after special treatment/polyurethane(PU) after special treatment, phenolic aldehyde,gelatine powder polyphenyl granule, etc. 3.thermal insulation material with grade B2 combustion performance: Molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane(PU), polyethylene(PE), etc.

Q: Which region use more refractory?: Places with steel mill, such as Hebei Province, Anshan City of Liaoning Province, south of Wuhan, Shanghai, all of these places have steel mills where use various types of refractories. In addition, architectural material industry, such as cement plant and glass plant all use refractories, but the variety is single, with a large amount.

Q: How many external wall thermal insulation fireproof material are there: External wall thermal insulation materials are generally divided by the burning grade, into class A, B grade. Grade A is non combustible material, grade B is combustible material. Class A which can be divided into thermal insulation mortar, bakelite plate, rock wool plate, foam cement plate etc.. Insulation mortar is relatively good, easy for construction, convenient, low cost, but its production process is too simple, so it is prone to fake. I recommend you to find a large manufacturing factory that posses complete procedure, for example, provincial production record, the provincial use record, municipal record, tset report at or above the provincial level, state fire proof report, design drawings of office building. product will not be safe if there is a lack of any of these documents. Burning level for henolic is uaually class B, but class A2 can be reached if a thin layer of mortar is applied on the suface,(A1 is the highest level of fire safety),intensity of phenolic is not high, finger pressing will leave a pit on it. if classified according to kilogram, raw material differs greatly every 10 kilogram. Rock wool is also classified by kilogram, general using 150kg wool. Rock wool are now comprounded with average strength. It will easily absorb water, having trouble applying paints. Foam cement strength is not high, easy to absorb water, It is not resistant to falling. It costs low, only used unless little profit can be made, Do not use it if worrying accidents would happen. These materials can be firstly burned, The palce the sample into water to see if it will dufuse at last. External wall should stand up to wind and rain. In terms of thermal insulation, they are almost the same, shows little differences on design thickness.

We has been adhering to scientific and technological innovation as the company development ideas, establishing the export-oriented development strategy and has close technical cooperation with scientific research institutions.We supply many kinds of calcined bauxite.
