- Q:what's the detailed address of fireproof and thermal inuslation matertial market?
- Following are the detailed addresses of fireproof and thermal inuslation matertial markets: Kunpengyu thermal insulation material co., LTD., Bantian street Daoban xuegang road 1-4, Jindu business building 503, Shenzhen Huameida rubber and plastic thermal insulation material wholesale, Shenzhen Longgang district Nanlian road 7, Nanpeng thermal insulation material Xiangxin road 1-4.
- Q:What material is refractory material?
- alumina refractory concrete, silica brick clay brick, metal ceramic, high temperature machine coating fiber reinforced ceramics, diatomite product, asbestos products, insulation board refractory. The definition of refractory can be searched in the website.
- Q:What are the requirements of refractory temperature of refractory brick?
- Oxygen fluctuation of load once happened during operation. Sometimes oxygen control valve will cause oxygen fluctuation of load, and sometimes large particles will block valve of high pressure coal slurry pump. The sudden drop in flow of coal slurry may cause relative excess of oxygen. Oxygen fluctuations directly cause fluctuations in furnace temperature. The range of oxygen fluctuations is 500m?-600m?. The maximum can reach about 1000m?. A sudden increase in oxygen causes a sudden increase in furnace temperature, which will suddenly burn out high-temperature thermocouple. The situation has a great influence on refractory brick and should be avoided. Furnace temperature is very inportant to life of lining of refractory bricks, so it should be strictly controlled not to overheat. There is a cinder layer on the surface of refractory bricks under the condition of normal production. In fact, cinder layer is dynamic. If the temperature is low, cinder layer is thick. If the temperature is high, cinder layer is thin. Appropriate cinder layer may slow the scour of high temperature gas and molten slag. The requirement of refractory brick is higher than that of stoves which use heavy oil as raw material. The main reason is permeability and corrosion of molten slag to refractory material. When replacing refractory bricks, it is found that penetration thickness is 10mm-20mm. After slag penetrates, strength decreases significantly. If temperature is high, erosion intensifies. According to the relevant information, when the operating temperature exceeds 1400 ℃, etching effect multiplies.
- Q:Kinds of refractory mortar
- Refractory mortar can be divided into ordinary refractory material and special refractory material. Ordinary refractory materials can be divided into acidic, neutral and alkaline refractory materials chemical properties. Special refractory material can be divided into high temperature oxide, refractory compounds and high-temperature composite materials according to their components. Furthermore, according to refractoriness, it can be divided into general refractory products (1580 ~ 1770 ℃), high grade refractory products (1770 ~ 2000 ℃) and super refractory products (2000 ℃ above). It can be divided into bulks (standard bricks, special-shaped bricks, etc.), special shapes (crucible, sagger, pipe, etc.), fibrous (aluminum silicate, zirconia filter and boron carbide , etc.) and indefinite shape (refractory clay, pouring materials and ramming mass, etc.). According to the sintering process, it is divided into sintered products, fused cast products and melting jetting products.
- 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:How many grades of fire?rating are there for interior decoration materials?
- It can be divided into structural material and base?material based on materials. It can also be divided into flammable, flame retardant and non-combustible materials based on fireproof types. There is no fire?rating for materials. But lengths of time of flammability limits are different.
- Q:How is the performance of refractory materials?
- It is a little difficult to answer. There are some requirement for refractory materials, such as fire resistance, softness, creep, thermal shock, abrasive resistance. Besides, requirements for construction performance include: Liquidity, plasticity and other linear change rate, volume density, strength (including high temperature) and all other important indicators must be tested the same conditions with the use of test conditions and test items like body density, strength, line changes in the basic project
- Q:What are the technical requirements for refractories?
- How high the temperature is and what is this refractory?
- Q:What are the components of refractory clay?
- The major raw material are bauxite, magnesite, silica, etc. It is easy to combine, high temperature resistant, corrosion resistant and has other advantages. It can be applied for refractory bricks in a variety of masonry.
