Q:Physical and chemical indicators of various refractory.: it depends on what it is for. There are thousands of kinds of refracroties. You should just ask what you need.

Q:Can quantitative feeder be used in refractory plant? Thank you: Well, can the Weifang Sanyou automation equipment production chain plate feeder is fully applicable to the measurement and control of boring high temperature, chain plate feeder with 16 4-5MM manganese plate.

Q:How to divide the materials according to the National Fireproofing Material Standard?: Each country has its own fire safety standards, I do not know which country's standard do you want to know, and each country of fireproof material to the division level is not the same. GB GB 8624, the German standard DIN 4102-1, the British standard BS 476, French standard NF P92 -501 and so on. GB 8624 is Chinese building materials and grade of combustion performance. The information coming form fire resources network (FireTC.

Q:I want to consult the fire resistant level standards of external wall thermal insulation materials.: 1, The thermal insulation material that has level A combustion performance: Spraying inorganic fiber, glass wool, foam glass, ceramic foam, rock wool, foam cement and perlite obturator, and so on. 2, The thermal insulation material that has level B1 combustion performance: Special processed extruded polystyrene board (XPS) / special processed polyurethane (PU), phenolic and polystyrene powder. 3, Thermal insulation materials that have level B2 combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See article 4.3.6 in the 2009 edition construction technical measures. Level A insulation material is just for fire protection, so its thermal insulation performance is worse than the organic XPS or EPS materials. Hope this will help you.

Q:What's the maximum temperature that the high-temperature resistant refractory ceramic fiber cotton can endure?: It depends on what material the ceramic fiber gasket uses. It’s usually referred to high temperature gasket made from ceramic fiber paper. It is generally classified into normalized form and high alumina type, of which the former can resist the maximum temperature of 1260℃ and its continuous use temperature is 1000℃, and the latter can be used for a long period at the temperature of 1200℃. Nichrome wire, stainless steel wire and glass fiber are reinforced. Ceramic fiber coating cloth and slag cloth, sintering ceramic fiber cloth and ceramic fiber fumigation cloth) Characteristics of the ceramic fiber cloth: It has high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment.

Q:For refractory knowledge. What is the ratio of clay ramming?mass?: Soil aggregates, dispersing agent, water reducing agent, plasticizer, binding agent and powder! ~ Bone meal feed approximately 6, OK

Q:Are refractory materials and fireproofing materials the same?: Refractories are generally used in the industry such as power plants, electric stove and industrial furnace. They include refractory bricks and insulation materials. Fireproof materials are generally used in building and they are fireproofing.

Q:Who knows about the fire endurance of grade C fire doors?: It can be classified according to the fire endurance and thermal insulation performance: The fire endurance of grade A fire doors is not less than 1.5 hours; that of grade B fire doors is not less than 1.0 hours; and that of grade C fire doors is not less than 0.5 hours. I hope my answer can help you.

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?: Physical and chemical property indexes of high strength and high alumina refractory bricksProject indexPLG-1.0 PLG-0.8 PLG-0.5 PLG-0.4AI2O3% 56545250Fe2O3%, 2, 2, 1.5, 1.5Bulk density g/cm3 1, 0.8, 0.5, 0.4Normal temperature compressive strength MPa shall be no less than 7531.5A change of a burn line of not greater than 2%The temperature is 1400140012501250 centigradeThe coefficient of thermal conductivity, W/m.k average temperature (350 + 5) is not greater than 0.45, 0.35, 0.25, 0.20

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.
