Q:Who know about the knowledge of acid refractory material? Please explain in detail.
Refers to the silicon dioxide
Q:As for fireproofing material rock wool and glass wool, which one is better?
Rock wool board and glass wool board are a kind of new construction thermal insulation material, it's widely applied in construction and has replaced traditional thermal insulation material to some degree. With the gradually deepening study of rock wool board, glass wool board, we can find that these insulation materials have advantages in many aspects but there are also many deficiencies, particularly there exists a lot of controversy about the impact on the human body. The production process of rock wool board and glass wool board usually includes: after melting in high temperature of rock or glass, inorganic fiber is produced by high-speed centrifugation equipment, and at the same time add binder,dust laying oil,silicone oil at certain proportion, then produce sheet material according to different requirements. It has good thermal insulation properties, mechanical property, sound absorption characteristics, belong to incombustible material and is cheap. In general, insulation, security and economy should not be contradictory, three aspects should be taken into account, balanced chosen and developed. Rock wool board and glass wool board and other such materials should be properly selected and applied to the appropriate structure, so that the choice of material will play their strengths and avoid their weaknesses.
Q:how to classify the fireproofing material levels A1 A2 B1?
their classification is shown specifically in Fireproof  Specification of Building Interior Decoration Design GB 50222-95 appendix A, flammability,inflammability materials, flame retardency, noninflammability: combustion performance of A, B3, B2, B1 materials are divided into
Q:Who knows how many fire heat preservation material are there?
Fire proof board is a fire refractory building material for surface decoration, widely used in interior decoration, furniture, kitchen cabinets, laboratories mesa, walls and other fields. Fire board is base paper (titanium powder paper, kraft paper) processed by melamine and phenolic resin, high temperature and high pressure. 1 mineral wool board, glass wool board: mineral wool, glass wool insulation. It does not burn itself, have good performance such as high temperature resistance, light quality. Such plate have evolved into plate with inorganic adhesive material as base material, mineral wool, glass wool as reinforcing material plate. 2 cement board: High strength, wide source. In the past, it is used to make fire prevention ceiling and partition wall, but its fire resistance is poor. Cement concrete component has good heat insulation and sound insulation performance. It can be used as the partition wall and the roof panel.
Q:Physical and chemical indicators of various refractory.
There are too many of them.
Q:What are the characteristics of phenolic resin as a refractory material?
Q:What are Grade-A waterproof inorganic thermal insulation materials?
There is a market confusion in Grade-A waterproof inorganic thermal insulation materials. The products mainly include Grade-A monomer material like roc wool and ultra-thin insulation board and Grade-A composite material. Many Grade-B materials wraaped with calcium silicate board or foam cement belongs to Grade-A material, such as phenolic aldehyde composite. Some foamed materials with filling also belongs to Grade-A material. However, there are few products with Grade-A qualification. Many manufacturers are working on the margins of the records with Grade-A fireproofing performance examining report. But this situation will not be too long.
Q:Where is the distributing center of refractory materials in China?
The construction of Gongyi Chinese refractory chemical industry professional market is a street in Yongan to implement the spirit of the six plenary session of the four session of the Gongyi municipal Party committee, the adjustment of economic structure, an important step in developing the service industry out of the. First, to promote the rapid development of the third industry. Through the improvement of refractory trade logistics system, make Yongan do truly become the first-class refractories trade and logistics center, driven by the refractory industry from the production area to the exhibition, logistics field extension and transformation, become refractory chemical industry center, Yongan office to promote the optimizing and upgrading of economy. Two is to promote intensive land development. Through the integration of resources, the unified planning of the reserved land, intensive development according to the standard of the city, the introduction of powerful investors, construction of large-scale projects. Three is to further create a business atmosphere in Yongan. Refractory chemical professional market operation, will promote the overall development of Yongan to do business, increase the flow of people, logistics, information flow, capital flow, more to promote the rapid development of the third industry in Yongan office.Gongyi Chinese refractory chemical industry professional market completion, will further promote the development of Yongan street service industry, accelerate the pace of economic restructuring, will run the streets of industrial upgrading has played a great role in promoting. Yongan road street is unprecedented high spirited gesture, innovation and development opportunities, so that industrial upgrading and optimization of the pattern to accelerate the realization of, we are convinced that Yongan's tomorrow will be better!
Q:What are the use of fire-resistant material and admixture?
I am engaged in admixture and thus familiar. Welcome to exchange!
Q:Which kind of refractory does insulation board belong to ?
