FUSED SILICA FOR REFRACTORY 1-3MM

Q: Which company needs the new refractories?: The power plants are mainly used in steel plant, lime kiln, coking plants, boilers, etc. I will try my best to answer what I can. There are too many glassworks. You can tell me more anout what you need. As long as there is a large kiln business, the refractories and aluminum manufacturer are needed.

Q: Technical scheme of refractory for refuse incinerator: Incinerator conditions and requirements for refractory lining1, working conditions: deal with rare earth, furnace body normal use temperature of 800~900 degrees.2, the specific requirement for refractory: refractory has good resistance to acid corrosion, thermal shock performance good stability and good high temperature.

Q: How much is refractory spraying coatings?: This depends on whether you use the thin coatin or thick coating. Then it depends whether you use an aqueous coating or oily one. Usually thick aqueous coating is 2-3 dollars per kilogram. While the thin is six or seven dollars per kilogram. The oily coating is more than ten dollars. The prices obtained from the Internet is for reference only.

Q: Kinds of refractory mortar: It needs no heating when hardened. There are two kinds of refractory mortar, the finished products and semi-finished products. Clinker is compounded in proportion according to the hardening temperature. (3) Chemical bonding refractory mortar is made from refractory aggregate and chemical binders (inorganic, high alumina refractory mortar). After this refractory mortar with thermal hardness is hardened, it has some contraction. Ther is a wide variety of refractories used on the constrcuction sites: // a, Advanced refractories (1770 ~ 2000 ℃) and AAA level refractories (2000 ℃ above). It can only be delivered in dry state. Air hardening refractory mortar is often compounded air hardening binders such as sodium silicate. It will harden below ceramic bonding temperature. According to different binding agents.

Q: How long is the fire-fighting time of A class fire resisting window?: Fire resisting window' duration of fire resistance: A class window, fire insulation ≥1.50h and fire resistance integrity ≥1.50h. Fire resisting window can be divided into three kinds: 一. window frame and sash framework adopt fire resisting window with steel manufacture ; 二. window frame and sash framework adopt fire resisting window with wooden manufacture; 三. window frame adopt steel and sash adopt wooden material or window frame adopt wooden material and sash framework adopt fire resisting window with steel material.

Q: what's the classification of fireproof and thermal inuslation matertial?: 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: Refractory factory grinding brick dust harmful to the body?: Therefore, in the workshop work must pay attention to do their own protection.

Q: What things and cement mixed can act as refractory?: Cement building, portland cement, refractory grade, calcium aluminate. Cement acts as refractory need to use calcium aluminate cement.

Q: Fire resistance and evaluation of refractory for casting: The refractory degree of refractory material at high temperature is called refractoriness. Refractory products all contain substances from fusible sintering action, the melt crystal as unlike at a fixed temperature, but the temperature in a wide range. At a lower temperature, a small amount of melt is formed, and as the temperature increases, the amount of the melt increases, and the product gradually softens. Refractoriness and melting point (crystal) are different concepts.
