Q: What is the strength of high strength refractory material?: Hefei Jiule decoration is answering your question: Use corundum as aggregate, high alumina cement as binder, mixed with a number of additives prepared, with high strength, and a hydraulic refractory casting material used in hot furnace lining at high temperature.

Q: What kind of fireproof material is used for steel structure?: Brushing or spraying the coating on the surface of steel structure to prevent burning and insulate heat. It also prevents undermining the rolled steel from rapid temperature elevation and avoid collapse of building for lose of supporting capacities. Agglutination material are classified as fireproof coatings for steel structures which is solvent based and Water-based steel structure fire retardant coatings. Fireproof coatings for steel structures which is solvent based are subdivided into fireproof coatings for steel structures which is solvent based with low benzene content and fireproof coatings for steel structures which is solvent based with high benzene content (TVOC≤600g / L, benzene ≤5g / kg). It can be divided by thickness. ultra-thin (CB) fireproof coatings (coating thickness ≤3mm), thin (B) fireproof coatings (3mm & amp; lt; coating thickness ≤7mm) and thick (H) steel structure fire retardant coating (7 mm & amp; lt; coating thickness ≤45㎜). The coating can be divided into non-intumescent fire retardant coating and intumescent fire retardant coating according to the the expansion properties. Slim (CB) and fire-resistant coating for steel structure and thin(B) fireproof coatings is intumescent fire retardant coating, thick (H) fire-resistant coating for steel structure is intumescent fire retardant coating. Unprotected steel structure has fire endurance of 0.25 hours.

Q: Which industry does refractory belong to?: It belongs to construction industry.

Q: How long is the fire endurance of Grade A fire resisting shutter: Based on national standards GB 14102-2005 specifications. It is specified in GB 14102-2005 provides that: The fire resisting shutter whose fire endurance is not less than 3h is AAA fire resisting shutter when the unexposed surface temperature rise is used as judging condition. Therefore, it is required that the fire endurance of Grade A fire resisting shutter is 3h.

Q: what's the classification of fireproof materials?: Fireproof materials are used in construction, in various forms and it has played an absolute role in modern fireproofing, common fireproofing materials include fireproof?panel, fire door, fireproofing glass, fire?retardant?coating, fireproof bag,etc Or the material itself has a high temperature resistance, heat-resistant, flame-retardant properties. Most of them are used for the construction industry.

Q: Who knows about the grade C fireproof door materials?: There are no differences in the interior materials of the grade A , B and C fire doors, they all use fire?rock?wool?boards. The only difference is the thickness of built-in fire rock wool boards. The rock wool boards' thickness of grade A fire doors is 52 mm, that of grade B is 46mm, and that of grade C is 40 mm.

Q: Detailed description of magnesia dolomite refractory material?: The use of low chromium or chrome free refractories is more and more widely used, developed countries in the development of chrome free refractories to replace the chromium containing material, through research and production practice show that dolomite refractories is the refining of AOD furnace, large cement kiln ideal material.

Q: Who knows the highest temperature the high-temperature refractory coating can resist?: The fire endurance of high temperature fire resistant coating is 3 hours. The fire endurance of fireproof is to go on fire resistance test of any building component according to the time- temperature standard curve, which is the period of time started from being put on fire and ended when losing support function or integrity has been destroyed or losing fire insulation function, expressed in hours. I hope my answer can help you. Thank you.

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.
