Q: What does fire-resistant insulation coating have?: What is the most famous is that grade A is incombustible?thermal?insulation?material. W W inorganic active wall insulation materials, cement foam insulation board, vitrified?micro bead?thermal insulation?mortar, rock wool board, glass wool board, foam ceramics, etc.

Q: Development trend of refractories: The foundation of China's refractories industry is still relatively weak, the utilization level of refractory material resources is low, the quality of refractory materials is not high, excess production capacity of ordinary products, the key products of some high-quality high technology content can be produced, but the quality is not stable, and the service life of refractory material consumption compared with foreign advanced level, there is a considerable gap. Therefore, the new trend of tracking foreign refractories science and technology development, carry out and supporting the development and application of advanced and basic theory research, to promote technological innovation of refractory materials, optimizing product structure, industrial structure adjustment, implementation of the strategy of sustainable development, it is very necessary.

Q: How to hang the suspended brick in the refractory masonry?: First you can fasten the girder and the suspended brick with screws, and then move them to the specified location by a crane. You can contact the refractory plant in Shanshan mountain, Ningxiang Countym, Hunan Province at 0731-7150098.

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: Who knows how to divide the building fire grade and fire resistance grade?: I hope to help you building fireproof rank division is one of the most basic measure in building fire safety technical measures, Building's fireproof rank is divided into class one, two, three, four according to China's architectural design specification. Fire-resistant capability of the highest level is the strongest; Fire resistance of four level of the weakest. The fire resistance level of a building depends on the combustion performance and fire resistance of the building components that comprise the building. The so-called building component refers to a series of basic components, such as wall, foundation, beam, column, floor, stair, ceiling and so on. The judgment condition of the fire resistance There are three conditions for components' fire resistance limit to be reached, namely, the fire resistance limit of the building component: Loss of support and integrity; loss of time to fire the role of the time; as long as any of these three conditions is met, it will reach its limit of fire. Hope my answer will help you.

Q: Where is refractory used? Thank you!: Currently, refractory is widely used as inorganic nonmetallic material of production equipment lining in metallurgy, ceramics and other industries. The current definition of refractory does not only depend on whether the refractoriness is above 1,580℃.

Q: Is the refractory reached British BS standard and used for cables in China at present ceramic silicone rubber?: The texture should be designed according to the British relevant BS standard; crosslinked polyethylene or ethylene propylene rubber under 6600V to 19000 / 33000V is not necessarily ceramic silicone. The rated voltages of a small amount of smoke and corrosive gases from 3800 & # 47 when the BS 7835-2000 is affected by fire.

Q: What are the differences of ceramics and refractories? Is the ceramics belonging to refractories?: Ceramic pottery ceramic collectively known species of high water absorption and low-grade sinter clay brick, tile-like material; high stone kinds of porcelain clay plus clay and other raw sintered body strength, low water absorption bowls, plates and other kinds of refractory high temperature structural materials are all non-machine ceramic refractory metal material belonging to a broader definition of ceramic refractory ceramic can be attributed to the high temperature ceramic refractory.

Q: Who knows the fire endurance of B-level fireproof doors and windows?: According to the fire endurance, fireproof doors can be divided into A-grade, B-grade and C-grade, whose fire endurance should not be less 1.2h, 0.9h and 0.6h respectively. Fire endurance of fireproof windows: A-grade fireproof windows are not less than 1.5h and B-grade fireproof windows are not less than 1h. The door leaves of A-grade and B-grade fireproof windows should be steel materials, and their glass should be composite fireproof glass whose thickness is no less than 26mm. Monolithic fireproof glass window is not B-grade fireproof window, nor A-grade fireproof glass window. It si called non-insulated fireproof window.
