A:Yes,We have.
- Q:What kind of materials are needed to make refractory bricks?
- Refractory materials generally refer to inorganic non-metallic materials with fire resistance above 1580℃. It plays an important role in metallurgy, nonferrous metals, chemical engineering, ceramics, and industrial production. Different industry needs different materials. You can turn to the knowledgeable internet.
- Q:Who knows what kind of fire protection material is better?
- Characteristic of polyurethane rigid foam thermal insulation decorative composite board: (1) ultra high cost performance, increased property's selling point (high cost performance) new model of thermal insulation material, excellent thermal insulation properties, elegant decorative effect, 50 years of service life, reduce maintenance costs and social waste. (2) it overcomes defects of traditional insulation technology (to solve the freezing and thawing, veneer cracking and shedding) traditional benzene board, the phenomenon of freezing and thawing that is easily appear in plastic extruded sheet, paint finish is easy to crack; its veneer facing can easily fall off; thermal insulation materials and wall are poorly adhered, easy off the whole. There is a themal bridge in dry hanging wall. (the characteristics of polyurethane composite board)
- Q:For refractory, why is it necessary to store the first mixing materials for some time under proper moisture and temperature?
- It is mainly to remove gas form chemical reactions in the pug, give full play to plasticity and binding properties of combined, and store unburned?brick whose cememting agent is phosphoric?acid or aluminium?phosphate for some time under proper moisture and temperature. For example, to avoid the formed bricks in the initial stage of drying and firing form cracking due to hydration of calcium oxide. Mixing materials is to store the first mixing materials for some time under proper moisture and temperature in order to improve the evenness and moldability of pud, such as making the distribution of combined clay and water more even. The length of storing chiefly depends on the process requirements and the characteristics of blanks. For the producing pug of high temperature kiln furnitures, the storing time is longer. The function of storing mxing materials varies with different natures of blanks. For honeycomb ceramics, it is to fully digest calcium oxide in blanks. For storing magnesia brick blanks containing much calcium oxide, it should be stored for some time in proper humidity and temperature.
- Q:How to divide the fire resistant level of EVB?
- According to the indicators of amount of smoke, heat value, burning rate, and ignition point, combustion performance insulation materials are divided into A (non-combustible), B1 (flame retardant), B2 (flammable), B3 (combustible). It can be divided into the organic and inorganic types: The organic includes polyurethane and polystyrene board, the inorganic the includes glass wool and rock wool. The price of organic is lower, and it is combustible materials, it will produce hydrogen cyanide and other toxic gases when burned, the inhaled would die. The inorganic material is completely non-combustible insulation material.
- Q:Is refractory material harmful to human body?
- The risk of mineral wool and glass fiber have cancer!
- Q:what's the requirements of refractory for forge furnace?
- High temperature resistance, good slag resistance.
- Q:What is the principal part of silicious refractory material
- Silicon nitride and aluminite powder as well as dextrin
- Q:What is shapeless refractory with high performance?
- The popular ones are: Non-cement fine powder bonded castable is a functional refractory castable with nano material introduced.
- Q:What kinds of refractory materials that can resist 3,000 Celsius degree?
- I think that graphite is the only one.
