FAQ
1 Your production capacity?
A: 3000 ton every month.
2 Will the free sample be provided for us?
A:We will provide free sample about 1 kg.
3 Did you have your own mancfactory?
A:Yes,We have.
- Q: What kinds of fireproof and fire retardant materials are there?
- fireproof materials are mainly non-combustible A material and flame retardant B1materials. Class A non-combustible material: Granite, marble, terrazzo, cement products, concrete products, plasterboard, lime products, clay, glass, tiles, mosaics, steel, aluminum, copper alloy; B1 grade flame retardant materials: Ceiling materials gypsum board, gypsum fiber boards, cement particle board, mineral wool acoustic panels, glass wool decorative acoustic board, perlite decorative acoustic board, flame retardant plywood, medium density fiberboard flame, rock wool decorative panels, retardant wood, aluminum composites, flame retardant phenolic plywood, aluminum foil, glass fiber reinforced plastic composite materials; wall materials gypsum board, gypsum fiber boards, cement particle board, mineral wool board, glass wool board, perlite board, flame retardant plywood, retardant MDF, fireproof plastic decorative plates, flame-sided particleboard, colorful paint, flame retardant wallpaper, wall covering flame retardant, flame imitation granite decorative plates, magnesium oxychloride cement prefabricated wall panels, flame retardant glass fiber reinforced plastic plate, PVC plastic sheeting, high-strength lightweight composite panels, fire-retardant molded wood composite board, color retardant plywood, fiberglass and other flame retardant.
- Q: How about the prospect of refractory material?
- is developing well. Many plants are required t o use fireproofing materials.
- Q: How can refractory material of the electric furnace be used for longer.
- Minimize mechanical shock, Electrical furnace commonly referred to must be electrical arc furance. The wall of electric arc furnace should be constrcuted with magnesite carbon brick. Its hearth permanent layer should be constrcuted with mansornary magnesia brick. High alumina brick is usually used to aviod furnace cover suddenly get hot and cold. But its service life is lower. At present integral casting furnace cover is made of alumina magnesia. Terminal will be created even without the use of refractory material. Consumption is much faster if using refractories material or whole knottiing mainly.
- Q: As for fireproofing material rock wool and glass wool, which one is better?
- As for fireproofing effect, the effect of rock wool is certainly better than glass wool , the highest temperature of rock wool is 1100 ℃, but the temperature of glass wool is only 600 ℃. In addition, if it's used in the external walls, then,unit weight of the glass wool is limited,and high unit weight can only be 60-90, but unit weight of rock wool can reach over 140, now external wall can't use glass wool, and only rock wool is A class fireproofing material. glass wool has lower thermal conductivity, rock wool has longer fiber length,as for the price, tons price of glass wool is more expensive than rock wool, but if it's acculated by square, square price of glass wool is cheaper than rock wool.
- Q: I wanna ask you, which level is b1 fireproof and thermal inuslation matertial ??
- I soppose you mean rubber and plastic! Only rubber and plastic has b1b2 level. Level b1 is the fireproofing level b1, because the rubber and plastic does not belong to the fireproofing material. It only has fire?retardant. The wholesale of all kinds of thermal insulation material and construction need to look at the name, hope you adopt.
- Q: What things and cement mixed can act as refractory?
- Cement building, portland cement, refractory grade, calcium aluminate. Cement acts as refractory need to use calcium aluminate cement.
- Q: What are the raw materials of refractory?
- Of course, different types have different raw materials: Magnesite (the electric?smelting: alkaline refractory, magnesia-carbon bricks, alkaline, high-purity) + crystalline flake graphite + phenolic resin + additive (silicon powder, aluminite powder, silicon carbide powder, or high-temperature asphalt,etc.) , acidic refractory: The neutral is not easy to answer. such as. You can check out the classification, such as
- Q: What are the chemical composition of refractory cement?
- Calcium aluminate prepared by calcining as the main component. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. Refractory cement is also known as aluminate cement.
- Q: Refractories for iron-making blast furnace?
- Cement kilns?
- Q: Who knows about the B-level fireproof insulation materials?
- Commonly used B-level materials: Molding polystyrene foam, extruded polystyrene board, gelatine powder polyphenyl granule heat insulating slurry. Although the polyurethane is not the commonly used material, but the 9mm composite of monolayer gypsum board and PU insulating material can reach B-level.
