- Q: Does anyone know the difference between refractory and thermal insulation material?
- I will give you a relatively simple analysis. Refractory can bear above 1,200 degrees centigrade, but some refractory is not insulated. For example, refractory brick can be directly in contact with heat source, but it has little insulation effect. Refractory includes ceramic fiber, high silica and so on. And they can be also insulated. But insulation effect is not so good as insulation material. Insulation material generally can bear below 800 degrees centigrade, and it is large in thermal resistance, low in heat conductivity coefficient and high in porosity factor, thus reducing heat loss. Briefly speaking, insulated material is to store most heat, and just let a small quantity of heat run of through air, thus insulating heat. Refractory includes glass fiber, rock wool, aerogel blanket and so on.
- 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: Who knows about the fire endurance of sintered shaly hollow bricks?
- Sintered shaly hollow bricks of Chu area have high intensity. The average compressive strength of them is up to 15.8, which matches with M7.5 cement mortar that has advantages of low water absorption, and good anti efflorescence performance. The fire endurance of sintered shaly hollow bricks should not exceed1050 degrees otherwise they will burn excessively. I, actually, think that the temperature should be controlled within 980 degrees. I hope my answer may help you.
- Q: Who knows the external wall thermal insulation materials fire rating requirements?
- The requirements of Department of Housing and the Ministry of Public Security No. 46: Residential buildings: the height of building is greater than 100 meters, the combustion performance of insulation materials should be level A. The other civil buildings: 24≤ height
- Q: The principle of choosing fire-resistant material in Thermal Energy and Power Engineering equipment.
- Different thermal technology equipment has different operation condition and select different refractory material. We should take economical and practical as principle.
- 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.
- Q: What refractories can withstand high temperature above 2100 degrees?
- You can refer to advices from the first one coupled with the second one.
- Q: What kinds of fireproof materials does the safe use?
- The fireproof materials of safe, copper is one of the most widely used material of locks for its good mechanical performance, corrosion resistance and processibility and beautiful colors.
- Q: How is the development of Xinmi refractories industry? What's its advantages and disadvantages?
- I don't know how it has developed. Its advantage is the coal industry. You have to know the generating capacity in Xinmi thermal power plant first, and then you will know their coal cinder yield, after all, this is the raw material. Xinmi is not far away from Zhengzhou. The real estate in Zhengzhou is still good. I'm not sure about the others.
- Q: Refractory inquiries
- Special refractories are new inorganic non-metallic materials developed on the basis of traditional ceramics and refractory materials.
