$Silicon Carbide Black and Green for Refractory$

Q:Which refractory is suitable for the tunnel kiln?: The refractories produced by the following ten manufacturers are relatively good. They are all being the top ten brands! 1. king coconut (Chinese well-known trademarks, famous brand, the nation's largest manufacturer of wood panels, large building materials chain enterprises, Hangzhou king coconut Holding Group Co., Ltd.) 2. Fuxiang (founded in 1998, the leading professional sheet production outstanding enterprises, Fuxiang Industrial Co., Ltd.) 3. Bunny (China famous brand, China Top brand, plywood industry iconic brand, large listed companies, high-tech enterprises, Edward Bunny decoration materials Co., Ltd. 4. new Millennium boat ( Chinese well-known trademarks, famous trademarks in Zhejiang, Zhejiang famous brand, well-known trademarks in Hangzhou, Zhejiang Province key forestry enterprises, the Millennium boat Group Hangzhou Huahai Wood Industry Co., Ltd.) 5. Jin Luli (China famous brand, Chinese brand-name products, Shandong Province, to wood-based panels and steel-based enterprises, hundred private enterprises in Shandong Province, Luli Group Co., Ltd.) 6. Albert (professional fire protection board development / production and marketing of the modern manufacturer, the introduction of advanced production technology industry HPL) 7. desert oasis (China famous brand lumber, China's top ten brands plate, sheet famous Chinese brand, oasis Wood) 8. Peng Che-hung (professional fire protection board development / production and marketing of the modern manufacturer, the introduction of advanced production technology industry HPL ) 9. Worldwide (professional magnesium fire plate glass production and sales of integrated large-scale well-known enterprises, famous brands Firewood industry) 10. Mogan (national key high-tech enterprises, China's largest and most influential environment-friendly decorative materials production one of the enterprises, Zhejiang Hua Yunfeng new material Co., Ltd.)

Q:What refractories can withstand high temperature above 2100 degrees?: It depends on refractoriness of refractory materials. The three refractory bricks above is 300 degrees higher than quartz sand in refractoriness. Magnesia brick: Cast corundum brick with greater than 2000 degrees refractoriness should be enough for you to use. But products like quartz sand merely keeps 1600 to 1700 in refractoriness generally. As you described that refractoriness is greater than 1990 degrees, it is feasible to use hearth made by mixing of quartz sand and refractory cement, which can work for some time at 200 degrees. It is also ok to use dolomite brick whose refractoriness is greater than 2000 degrees.

Q:What are the requirements when producing fireproof materials by kaolin?: . Kaolin are kaolinite crowded mineral composed of tiny flakes tubulose, lamellar smaller than 2 microns. it is composed of kaolinite, dickite, pearl stone, halloysite etc. I chemical formula of which is AL2O3-2SiO2-2H2O, the main mineral component is kaolinite and halloysite. Except kaolinite and halloysite there are other minerals montmorillonite, illite, pyrophyllite, quartz and feldspar associated. kaolin contains large amounts of the chemical composition AL2O3, SiO2, and a small amount of Fe2O3, TiO2, and small amounts of K2O, Na2O, CaO and MgO, etc. white pottery is made of kaolin and is now internationally accepted scientific name --Kaolin, derived from the eastern suburb of Jingdezhen high-Village side of the mountain kaolinite. kaolin plasticity, cohesiveness, certain dry strength, sinterability and whiteness after burning, making it the main raw material for ceramic production;. white, soft, highly dispersed, adsorption and chemical resistance with other excellent process performance, it has been widely used in the paper industry as well as industrial sectors such as agriculture and defense cutting-edge technology in the field of rubber, plastics, refractories, petroleum refining . according to the purpose and need, it can be processed, treated and purified, they can be used to produce activated clay.

Q:Which kind of external wall fire barrier zone material is better?: The following types are: rock wool, aerated concrete, phenolic aldehyde and foam cement rock wool fire barrier zone "rock wool board" mainly uses water-repelling rock wool board produced by pendulum method as thermal insulation layer materia, and connecting and fixing base wall by binding and nail bonding, it is composed level A non-combustible building energy efficiency thermal insulation system by plastering layer composed by plastering mortar and glass?fiber mesh and decorative mortar finishing layer or coating. Good air permeability

Q:What do RH and DH stand for in refractories?: DH :For human intelligence (diameter, board of directors). )

Q:Does anyone know what kind of light fireproof materials are there?: 二, 1, Gypsum plaster board With the building plaster as main raw material, gypsum plaster board is a kind of processed plate made by a special board for protective with an addition of additives and fibers as board core. Gypsum plaster board is characterized by light weight, sound insulation, heat insulation, strong processing performance and simple construction method. 2, Gypsum block Gypsum block is a kind of lightweight building gypsum product which is mainly made of building gypsum, and by adding water, stirring, casting and drying. During the process, , the fiber reinforced materials or light aggregates are allowed in, and the foaming agent can also be added. It has many advantages, such as sound insulation and fire prevention, convenient construction and so on. It is a kind of new and healthy wall material which produces low carbon, enhances environmental protection, and caters to the the times. 3, Fly ash brick is a new type of wall material, and bulk density is one of the main technical indexes. The weight of bulk density can be controlled according to the need of construction and adjustment of technical formula. The dry bulk density of the fly ash brick is about 1540 to 1640 kg / m 3, slightly lighter than the clay brick (1601800 kg /m 3). The flexural and compressive strength of fly ash brick is mainly determined by the production process, the formula and the hydrothermal synthesis reaction mode as well as the need of construction. According to the standards of architectural material industry (JC239 - 2001) released by People's Republic of China, the average value of the flexural strength is 2.5 ~ 6.2Mpa, compressive strength is between 10 ~ 30Mpa. I hope this will be helpful to you

Q:I wanna ask what are the acidic refractories?: You can look at these: (1) silica?brick with stronge acidity, unshaped silicious refractory, quartz glass and fused silica combined products; (2) semi-silica refractory with moderate acidity and pyrophyllite refractory; (3) clay-based refractory with weak acidity. I hope it is useful!

Q:hat kind of fire retardant materials are there: There are many flame retardant plastics, which are modified on the basis of raw materials, such as flame-resistant ABS, flame-resistant HIPS, flame-resistant PP, flame-resistant PE, flame-resistant the PET, flame-resistant PBT, flame-resistant PC, flame-resistant PC/ABS alloy. Now there are mainly halogen flame retardant, though there are a lot of researches about halogen free flame retardant, the product stability and flame retardant effect remain to be improved. Testing methods of flame retardant materials are mainly: horizontal and vertical combustion, oxygen index method, NBS smoke box , thermal analysis, cone calorimeter, etc.

Q:How to distinguish the fire resistant level of construction materials?: Building materials fire resistant level is divided into four levels, among which the first level is the highest, with strongest fire resistance; fourth level is the lowest with weakest fire resistance. Fire resistance level of buildings depends on combustion performance and fire endurance of the building components. The building components refer to a series of basic components such as the building walls, foundations, beams, columns, floors, stairs, ceiling, etc.

Q:What is the most reasonable drying heating curve of magnesia refractories? Products of less than 0.5T: o
