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: Who knows about roof fireproofing materials?: Roof water proofing materials: synthetic polymer waterproof rolls, high polymer modified asphalt waterproof coiled material, sheet metal, synthetic polymer waterproof coating, one-component water curing polyurethane waterproof coating, penetration crystalline waterproof coating. Secondly, we have to choose materials that are suitable for roof water proofing. The right waterproof materials have better waterproof performance, TS-3B one-component water curing polyurethane waterproof coating is very suitable and the performance is good. Since traditional roof waterproofing materials have requirements on the moisture content of the formation level which should be less than 9%. It is really important to choose which materials to repair leaking roofs. Kitchens and toilets are moisture, the formation levels of buildings are hard to satisfy requirements, thus, waterproof?layer and formation level are easily get separated and are ineffective in waterproofing.

Q: What's the maximum temperature that the refractory ceramic fiber cloth can endure?: It depends on the composition of the ceramic material. If its composition is alumina and it is used by civilians, its normal use temperature is 1200℃; if its composition is alumina but it is for millitary use, it can endure the highest temperature of 2200℃.

Q: Does hardware construction materials contain refractory?: refractory includes one kind of building materials. It is a special material and not commonly used.

Q: What kind of refractory materials should be used for the intermediate frequency furnace to smelt manganese?: I am not quite clear. But you should take two aspects into consideration, namely, no pollution and strong durability.

Q: What is the fire endurance of fireproof glass cotton?: of course,A level is better. A-class is non-combustible, class B is fire retardant, rock wool fire resistance is 800 ℃, glass wool fire resistance is 450 ℃ , class B has a relatively better thermal insulation effect, hope it can solve your doubts.

Q: What are the characteristics of clay refractory materials?: Refractory clay refers to the refractory clay and bauxite, whose refractoriness is over 1580℃, which can be used as refractory materials. Apart from high refractoriness, they can maintain stability of volume under high temperature conditions and has resistance to slag, the sudden cold and hot, and mechanical strength, so after calcination, it can be abnormal firm.

Q: What is the the best matching ratio of refractory cement?: The best matching ratio of refractory cement is 30%. Refractory cement is also known as aluminate cement. 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. Aluminate cement is often yellow or brown or gray. The main mineral of aluminate cement is mono calcium aluminate (CaO · Al2O3, abbreviated CA) and other aluminates, and a small amount of dicalcium silicate (2CaO · SiO2), etc. It is a special cement. I hope my answer will be helpful to you.

Q: It the Special Fire-Proof Material belonged to ceramics? Is there a national standard of the Special Fire-Proof Material?: The fiber and reinforcing material of the metal ceramic is also belonged to the Special Fire-Proof Material. ~~~~GB is too much trouble, GB online should ~~~ Lei Bao Refractories for you. The high temperature inorganic coating. 5. The refractory compound. 3. The high melting point oxide. You can search it on the internet according to the classification~~~~ The special refractories can be divided into five categories: 1. metal ceramic

Q: Who knows how many poured refactory material are there?: Casting refractory material, refractory material used often are AZS brick, corundum brick, direct bonding magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide brick, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, aluminum oxide, magnesium oxide, beryllium oxide and other refractory materials.
