$Silicon Carbide Black and Green for Refractory$

Q: How to use fire-resistant soil?: Clay refractory soil 1, characteristics and uses: Clay refractory brick is a weak acid refractory material, its thermal stability is good, suitable for hot air furnace, all kinds of boiler lining, and flue, smoke room, etc.. 2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.

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: Does anyone know the difference between refractory and thermal insulation material?: I will give you a relatively simple analysis. Refractory can bear above 1,200 degrees centigrade, but some refractory is not insulated. For example, refractory brick can be directly in contact with heat source, but it has little insulation effect. Refractory includes ceramic fiber, high silica and so on. And they can be also insulated. But insulation effect is not so good as insulation material. Insulation material generally can bear below 800 degrees centigrade, and it is large in thermal resistance, low in heat conductivity coefficient and high in porosity factor, thus reducing heat loss. Briefly speaking, insulated material is to store most heat, and just let a small quantity of heat run of through air, thus insulating heat. Refractory includes glass fiber, rock wool, aerogel blanket and so on.

Q: What is the difference between wear-resistant material and refractory material?: There must be difference. The requirements of refractory material are that it can be called refractory material when temperatures it can withstand are over 1570 ℃. Refractory material must have high strength. The specific value of refractory material is not clear.

Q: Why does refractory need to add coarse firstly and then add fine aggregate?: Adding coarse aggregate is to assure its good combination with fine aggregate. This is just the experience. You don't have to ask.

Q: how to divided the external wall thermal insulation materials fire rating: Level A: Incombustible building material: It is a kind of material that almost does not occur burning. Level B1: Nonflammable building material: Non-flame material has good flame resistance. It is difficult to fire under the condition of open fire in the air or high temperature, and it is not easy to quickly spread, and when the combustion?source is removed, the combustion will stop immediately. Level B2: Combustible?building?materials: Flame material has a good flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as wooden column, timber roof truss, timber beam and wooden stairs. Level B3: Combustible?building?materials: It has no any flame resisting effects, and is easy to burn, so the fire risk is high.

Q: Selection of refractory materials?: Inorganic non-metallic material with a refractoriness of more than 1580 degrees. Refractoriness refers to the temperature of a sample of a refractory cone, which is resistant to high temperature without softening, and does not soften and melt down. Refractory materials are associated with high temperature technology, which originated roughly from the middle of the bronze age. In the Eastern Han Dynasty has made China kiln firing porcelain material and with fireclay refractory sagger. In the early twentieth Century, refractory materials were developed towards high purity, high density and ultra high temperature products. At the same time, unshaped refractory materials and refractory fibers without firing and energy consumption were developed. With the development of modern technology, atomic energy, space technology, new energy technology, refractory material having high temperature resistance and corrosion resistance, thermal shock resistance, erosion resistance and other comprehensive excellent performance has been applied.

Q: what's the varieties of thermal insulation material with A level fire?rating?: Inorganic thermal insulation material can do it, such as glass wool,rock wool,foam glass,etc. phenolic foam materials in organic foam material is special. phenolic foam not only has good thermal insulation properties but also can be composited with steel plate and other materials, A class thermal insulation materials that reach A class combustion performance include: rock (mine) wool, foam glass, EVB, etc. thermal insulation materials with A class combustion performance mainly include: phenolic aldehyde,gelatine powder polyphenyl granule, etc. thermal insulation material of fire barrier zone can use rock (mine) wool, foam glass, EVB and other materials with A class combustion performance.

Q: What is the quote of fireproof and soundproof materials used in KTV?: acoustic material, aluminum foil glass wool, sound-deadening material, glass wool, cinema / KTV dedicated glass wool: The classification of glass fiber products: The category of glass wool felts: The level of insulation cotton: A-level brands: New applications: The origin of GB/T13350-2008: The coefficient of thermal conductivity(room temperature): 0.035 bending at low temperature≤： 0.02 elongation at break: ≤80kPa flexure strength： ≤120kpa Compressive strength: ≤150kpa application temperature: 700 Core material: The shape of glass wool: Fibrous shape: Coil Specifications: Complete quote is 23 Yuan per cubic meter. glass wool board, KTV sound insulation core material: The shape of glass wool: The level of rectangular glass wool: A-level non-combustible brands: Kunnai material: The origin of glass fiber: Guangzhou, Shijiazhuang, Wuhan, the quote there is 8.8 Yuan per cubic meter.

Q: Who knows the fire endurance of rock wool color plate?: Colored steel rock wool board is used for areas with high fireproofing requirements. Colored steel rock wool board belongs to class A according to "Fireproof? Specification of Building Interior Decoration?Design" whose lifetime can reach more than 15 years, operating temperature can up to about 700 ℃, maximum fireproofing time is 6 hours. And rock wool colored plate is environmentally friendly materials, which is is the preferred material in the construction industry .
