- 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: How about the prospect of refractory material?
- is developing well. Many plants are required t o use fireproofing materials.
- Q: Who knows what is the external wall thermal insulation materials for level A fireproofing?
- external wall thermal insulation materials level A fireproofing: Incombustible building material is a material that does not occur any burning. Class A1: Monomer inorganic non-combustible. Noncombustible means no open fire. Class A2: Non-flammable organic compound is namely composite materials and non-flammable, the amount of smoke must be qualified. Class 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. Class 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.
- Q: The effect of a high content of water in liquid resin exerted on refractory material?
- For one thing, Substandard whiteness, transportation, low quality and the storage of refractory material may account for this. For another, a high content of moisture reduced the performance of refractory material. A high content of moisture is equal to buy water with same money in terms of trade settlement. Based on this, we can’t consider the super-standard water content from a single aspect, because the water content in refractory material is definitely super-standard, and another problem is particle size. Many people hold the idea that excessive amount of water content may revive its original performance, but it tends to have influenced the quality of refractory material.
- 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: Fire rating of decoration materials
- All light steel keel gypsum board is considered level A; if the wood finishes up to B2 grade fire rating depends on the proportion of the use of wood veneer and the proportion of this wood veneer fire grade, if the proportion of wood veneer is small,it can be considered level A
- Q: what is the fireproofing material of engine room? who knows it ?
- 1. The new type fire?retardant?coating in fire retardant coating, the expanded vermiculite, expanded perlite heat insulation material and cenosphere adiabatic powder, etc. These inorganic component, is a major part of the thick coating type of fireproof coating, and they also are the major factor affecting the level of performance of fireproof coatings. The fireproofing thermal insulation properties of fireproof coating, is mainly determined by the fire back surface temperature of this factor, but also related to the fire endurance. If it reaches the same temperature for a longer time, it shows that it's fireproof thermal insulation is better, and the fire endurance therefore is higher. 2. The new fireproof board new fireproof board now is welcomed by the people and the important factor is its environmental protection, and with the increasing high-rise buildings, the fire protection requirements and strength requirements are also rising, it is a big challenge for the performance and standard of the fireproof board.. Now fireproof board is mainly used siliceous material or calcareous materials, and then mixed with the fiber material, lightweight aggregate, adhesives and chemical additives, it is not only be fireproofing, but also improve their thermal insulation performance, and light weight, good carrying capacity, good durability, no aging problem, more importantly, it is good in environmental protection.
- Q: what is the specs of thermal insulation refractory slab ?
- it is produced in accordance with scientific formula by using asbestos, glass fiber and potclay . it has strong tension strength capable of withstanding 1400 degrees Celsius, specifications!: 1.5DD20 (mm)
- Q: How many types of fire-resistant material?
- 1. Acid fire-resistant material refers to one with more than 93% SiO2. It is featured by resistance to the corrosion of acidic slag ad high temperature and easy to react with alkaline molten slag. 2. Alkaline refractory material generally refers to one with magnesium oxide or magnesium oxide and calcium oxide as the main component. It has high refractoriness and strong resistance to basic slag. 3. Silicate aluminum refractory material refers to one with SiO2, Al2O3 as the main component. According to the content of Al2O, it can be divided into three categories: half siliceous (15-30% Al2O3), clay (Al2O3 30 ~ 48%), high aluminum (more than 48% of Al2O3). 4. Fused cast refractory material refers to shaped refractory products made by high temperature melting and casting.
- Q: What kinds of refractory materials that uses a-Al2o3 powder? What are the purpose of it?
- 04La-Al2O3 powder is a alumina powder whose raw material is industrial aluminum oxide which has been calcined at high temperature. It is a good polishes for ceramics and jade, meanwhile, it is also an important raw material for high-end refractory materials. The technical indicators parameters A1023 mark A1535 chemical composition AL2O3≥ 99.92 3%, ≥ 3.10FE203≤ 0.799 Refractory calcined alumina powder (a-Al2O3) 1.2 true density (g & # 47, by fully ground powder made of different fineness .O.10 0.07 0.04NA2O≤ 0.93a-Al2O3 (%) ≥ 95 95 primary crystallization average grain (um) 2 ~ 3 3 ~ 5 average particle size (um) 40 ~ 602.6SIO2≤ 0.1 0.15B2O3≤ - 0, glass, engineering ceramics typical use electronic ceramic insulating ceramic refractory ceramic wear 3
