- Q: Does anyone know the refractory temperature of fire-resistant glass?
- Ordinary glass will be completely liquefied in the furnace of about 1100 degrees for half an hour and will not deform below 600 degrees. toughened glass fire-resistant glass is the product of ordinary glass after being processed Glass will mainly burst after encountering fire. When unevenly heated or encountering sudden drastic changes in temperature, ordinary glass will burst if the sharp temperature difference is over 70-120 degrees and toughened glass will burst at 200 degrees. It is not yet clear of the bursting temperature for the refractory glass. (I hope this answer can help you!) Hope you adopt !)
- Q: Refractory net
- The development of the industry of refractory materials is very good, manufacturers are also more and more, especially in the Henan Xinmi side, next to the factory factory, we had visited gold refractory material factory, the scale is very large.
- Q: What are the meanings of azs, 34% and ec in fused brick?
- The fused brick, also called zircon corundum brick, is shorted as AZS for three chemical components in Al2O3-ZrO2-SiO2 ternary diagram. I don't know the meaning of EC.
- Q: What are the physical properties of refractory material?
- The mechanical properties of refractory material include compressive strength, volume density and sclerosing, slag resistance, elastic modulus, thermal shock resistance, oxidation resistance, bibulous rate, fluidity, resilience, bond strength and slump, electrical conductivity, specific heat, heat capacity, the impact strength, linear change, torsional strength, stomatal aperture distribution, resistance to acid, etc. The use performance of refractory material include refractoriness, thermal emissivity, condensation, porosity, coefficient of thermal expansion. Thermal properties of refractory material include thermal conductivity, temperature conductivity, plasticity, the hydration resistance, creep performance. The physical properties of the refractory materials include structure performance, mechanical properties, shear strength, load softening temperature, CO erosion resistance. The structure properties of the refractory materials include porosity, alkali resistance and sintering. The operating performance of refractory material include consistency, tensile strength, the use performance and operating performance, wear resistance, bending strength, thermal properties.
- Q: What's the heat conductivity coefficient of fire-resistant material?
- There are many types of fire-resistant materials woth different thermal conductivity. The question should be more specific.
- 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: 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: What are the requirements on fire resistance period of C-level fireproof glass?
- Class C: The fireproof glass which only meets demand of fire integrity. This glass has advantages of transmittance, fireproofing, smoke resistance and high intensity. It can be applied to fireproof glass partition walls, fire windows and with no requirements on outdoor curtain walls, etc. The fireproof glass can be classified as composite fireproof glass and single chip fire-proof glass in terms of structure. Class B: The fireproof glass which meets demands of fire integrity and thermal radiation intensity at the same time. This glass is mostly composite fireproof glass which has advantages of transmittance, fireproofing, and smoke resistance.
- Q: Who knows about the types of Dalian thermal insulating and refractory materials?
- There are mainly following types: rock wool series, rubber and plastic series, glass wool series, mesh series, ventilation series, mortar series, extruded sheet series, geothermal series, insulation supporting pin series, glass silk cloth series. I hope my answer can help you.
