Q:What is the the best matching ratio of refractory cement?: The ratio of cement and sand is about 30 per cent. Properties and Applications of refractory mortar: 1, Good plasticity and easy construction; 2, High bonding strength and strong corrosion resistance; 3, Relatively high refractoriness up to 1650 ℃ ± 50 ℃; 4, Good slag corrosion resistance; 5, Good thermal peeling. Refractory mortar is mainly used in coke ovens, glass furnaces, hot blast furnace and other industrial furnaces. Applied industry: Metallurgy, building materials, machinery, petrochemicals, glass, boiler, electric power, steel, cement, etc. And 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.

Q:what is the grading standards of external wall thermal insulation materials?: What is the grading standards of external wall thermal insulation materials? summarizing the three versions of GB8624 (1997,2006,2011) external wall insulation fire rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. the dividing is based on many technical indicators. It takes time to explain for It is professional and technical. For details, please contact Qingdao Shan Textile Instrument. they specialized in external wall insulation fire rating tester.

Q:Does the aluminum silicate thermal insulation material fireproof?: With stable performance,long fiber length, strong tensile strength, strong seismic performance, low shot, light unit weight, low thermal conductivity, good insulation properties. it is not bad.

Q:What kinds of refractory materials that uses a-Al2o3 powder? What are the purpose of it?: 04La-Al2O3 powder is a alumina powder whose raw material is industrial aluminum oxide which has been calcined at high temperature. It is a good polishes for ceramics and jade, meanwhile, it is also an important raw material for high-end refractory materials. The technical indicators parameters A1023 mark A1535 chemical composition AL2O3≥ 99.92 3%, ≥ 3.10FE203≤ 0.799 Refractory calcined alumina powder (a-Al2O3) 1.2 true density (g & # 47, by fully ground powder made of different fineness .O.10 0.07 0.04NA2O≤ 0.93a-Al2O3 (%) ≥ 95 95 primary crystallization average grain (um) 2 ~ 3 3 ~ 5 average particle size (um) 40 ~ 602.6SIO2≤ 0.1 0.15B2O3≤ - 0, glass, engineering ceramics typical use electronic ceramic insulating ceramic refractory ceramic wear 3

Q:What are fire resistant level standards of class A fire resistant door?: Executive standard: GB12955-2008 Fire Door. Fire resistant level: Class A: 1.5h, B:1.0 h, C: 0.5 h. Thickness of door leaf: Class A: 50mm, B 45mm, C 40mm. Doorframe Specification: Class A, B, C. Door leaf form: Single open, double open, single open with glass, double open with glass, single open with glass and bright, double open with glass and bright, with a bright picture, Zimu glass Zimu glass with light. Doorframe Specification: Class A, B, Door leaf form: Single open, double open, single open with glass, double open with glass, single open with glass and brightness, double open with glass and brightness, double open with a lager door leaf and a smaller door leaf, double open with a lager door leaf and a smaller door leaf with glass, double open with a lager door leaf and a smaller door leaf with glass and brightness. Standard sizes: In line with GB5824-86 Hole Size of Building Doors and Windows."

Q:What high-molecular polymers can be used as fire-resistant material binder?: Melamine resin should be compounded with fire-resistant material and acrylic acid material is easy to burn. But high-molecular polymers can be used along with the above two. Polysulfone is featured by heat resistance and high temperature resistance. Polyurethane is difficult to process and compound with fire-resistant material. Phenolic resin is not easy to burn. Epoxy is expensive and self-extinguishing once away from fire.

Q:Who knows the fire rating of fire?partition with steel stud?: Cement board wall of steel stud: it is used for walls with ceramic in kitchens, restroom, disinfect room, etc. If single-sided tile is made, cement pressure plate can be used on one side. Gypsum board is used on the other side. Fire?rating is A1. CaSo4.2H2O is molecular structural formula of gypsum which contains 20% water, crystal water and free water. When 10% water slowly evaporates on the flame surface, there is still 10% crystal water. Itself is grade A fire retardant material. 1 hour. It is in line with the fireproof test standard of national building materials. It can reach up to 4 hours at most.

Q:What are grade classifications of the external walls for fireproofing?: The basic level can be divided into: A1, A2, B1, B2, B3 and other levels. There are many technical indicators to make specific division, but I partly cannot report for a while, because it is very professional and technical. Please contact Qingdao Shanfang Instrument Co., LTD for details, they specialized in the external wall thermal insulation materials fire?rating testers.

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:What are the construction measures of refractory material in winter? Please descriptive briefly.: The temperature is low in winter, so refractory bulk materials should be stirred evenly on time to avoid freezing.
