Q: what's the standard of fireproofing material?: Class A1 is divided according to the combustion performance of GB8624-2006 building materials and products. Specific technical index requirements are: 1, the temperature rise ≤30 degrees;mass loss rate ≤50%; combustion duration time is 0; 2, main components, overall products, gross calorific value of external secondary components ≤2.0MJ/kg; any inner secondary component ≤1.4MJ/kg; (there are difference between homogeneous and non-homogeneous). Z802 building materials noninflammability testing furnace has to be used for testing technical indicators mentioned in test 1, using Z805 building materials combustion heat value to test technical indicators mentioned in test device 2.

Q: Which company needs the new refractories?: The power plants are mainly used in steel plant, lime kiln, coking plants, boilers, etc. I will try my best to answer what I can. There are too many glassworks. You can tell me more anout what you need. As long as there is a large kiln business, the refractories and aluminum manufacturer are needed.

Q: What are the applications of refractory?: Refractory materials are widely used in iron and steel smelting , glass, cement kilns, non-ferrous metal metallurgy, environmental protection, and chemical, etc. For example: For a car of 1.5 tons, do you you know how much refractory it use? The answer is: To produce top hat or other steel products, glass for vehicle windows, nonferrous metals kile aluminum and copper, plastic products of the body all needs refractory. A car of 1.5 tons needs to consume a total of 10Kg refractories.

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: 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: Which kind of external wall fire barrier zone material is better?: I recommended foam cement and particulate thermal insulation composite waterproof material, which is fire isolation area product, which uses surface of vertical?plate arranged fiber technology to make the compressive?strength in the vertical direction up to above 80KPa. At the same time, under the conditions of both exterior heat insulation and effects of humiture in the long-term, it can still maintain the non-aging performance of various aspects, and safety (reliability), fire resistance and excellent durability.

Q: How many refractories are there for boiler above 1200 ℃？: Ordinary clay brick is for burning layer, red brick for external wall, light clay brick for thermal insulation layer, built by clay refractory mortar. Sindeyuan Refractories.Hope you adopt. Thank you. In fact, there are many manufacturers producing furnace burden. We has been using products of Huaheng, which are anti-erosion, easy to construct and can improve production efficiency, reduce steelmaking cost.

Q: Why should graphitic refractory materials be used now that graphite can burn?: C is inactive in nature. Carbon will not burn unless the temperature is about 2000℃, so it can't be lit generally. Coal can be lit because it contains other combustible substance which ignite carbon indirectly. While graphite, carbon black, is more pure and dense than coal., so it is hard to oxidize.Their molecular structures are also different, just like diamond is harder than graphite.

Q: Why the corundum can be used as refractory: Do you need white corundum Its main chemical element of corundum is the 99.3% aluminium oxide and it is sintered byelectric furnace, so it can be used as a refractory raw material, the other can also be used as grinding wheel. It is very useful
