- Q:What are the standards of refractory concrete ?
- The special concrete compound by uitable binding materials, refractory aggregates, admixtures and water at a certain ratio. It can maintain the desired mechanical property at high temperature of above 900 ℃ for a long time. The property depends on the material and matching of all the aggregates, admixtures and binding materials. Its material, composition and ingredients are similar to these of refractory castable. Refractory aggregate can be dry slag, broken refractory bricks, basalt, bauxite, magnesite, etc. According to the binding material, it can be divided into Portland cement refractory concrete, aluminate cement refractory concrete, sodium silicate refractory concrete, phosphate refractory concrete, magnesia refractory concrete, etc. (8) The particle material and powder material in refractory concrete are called aggregate and admixture respectively. The mixture of concrete can be moulded by casting, vibrating or ramming. And proper measures to promote their hardening can be used in accordance with the hardening characteristics of the binding materials (such as air hardening, water hydraulicity, thermal hardness, etc.). It is mainly used to build the monolithic lining of industrial furnace and procast blocks. Of all the concrete, the ones used for under 900 ℃ is called heat-resistant concrete, and they are used for the foundation and chimneys, etc. of industrial furnaces and thermal equipment.
- Q:What are grade classifications of the external walls fireproofing material?
- There are many kind of external walls fireproofing material, according to the document No. 65, the grade of external wall fireproofing material can be divided into: Level A is inorganic insulation non-combustible materials, such as cement foam insulation board, vitrified?micro bead?thermal insulation?mortar, rock wool board, glass wool panels. Level B1 is nonflammable material, mostly are organic material which has added a relatively large amount of flame retardant, such as polystyrene board, extruded sheet, phenolic foam board and polyurethane board. Level B2 is flame-retardant materials, and also known as fire-retardant materials, mostly are organic insulation materials with appropriate amount of flame retardant.
- Q:how is the high-temperature flame-retardant fibre board?
- Still good, we still can understand, we still feel good, I still can understand the amount of
- Q:What is the requirement of refractory concrete for raw materials? What is the main principle of commercial mixing station?
- Refractory concrete generally divided into three categories: lightweight concrete (used in insulation); refractory concrete (for refractory temperature requirements are not very high position, and can withstand a certain air scour); heavy refractory concrete (flow with higher requirements for refractory temperature parts, and can withstand a certain intensity). Mainly depends on the design temperature and the use of parts.
- Q:Who knows about roof fireproofing materials?
- Roof thermal insulation materials are various which generally can be divided into two categories, namely inorganic and organic materials: Inorganic materials are expanded perlite, aerated concrete, rock wool, glass wool, etc. Organic materials are styrofoam, polyurethane?foaming?plastic and so on. A. common roof thermal insulation materials 1. the expanding polystyrene board (EPS) has good thermal insulation performance, and cheap price but poor intensity with heat conductivity coefficient of 0.038-0.041. 2. extruded polystyrene board (XPS) has better thermal insulation performance and high intensity but an expensive price with heat conductivity coefficient of 0.028-0.03. It is moisture resistant but needs treatments on surface in construction. 3. rock wool board, with heat conductivity coefficient of 0.041-0.045, is fireproofing, fire?retardant. It has a good hygroscopicity performance but is poor in thermal insulation. 4. gelatine powder polyphenyl granule heat insulating slurry, with heat conductivity coefficient of 0.057- 0.06, has a good flame resistance performance, but the results of recycling and thermal insulation are unsatisfactory. It has high construction requirements. 5. polyurethane foaming material, with heat conductivity coefficient of 0.025-0.028, has good waterproofness and thermal insulation performance, as well as high intensity, but it is expensive. 6. perlite and other slurry, with heat conductivity coefficient of 0.07-0.09, have good flameproofness and water-absorbing ability but are poor in thermal insulation and thermostability.
- 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?
- steel fiber reinforced spalling resistant bricks, phosphate bonded high alumina brick with high strength and wear-resistance, and high R.U.L bricks and composite bricks
- Q:Can I use ordinary cement with the addition of sand, clay, and salt as refractory material to paste the stove?
- Add some hair and slags, or it will crack before calcination.
- Q:How long is the duration of fire resistance that fireproof window of level B can endure?
- The duration of fire resistance: fireproof window of level A shall not be less than 1.5h, while level B shall not be less than 1.0h. The frame of both fire proof windows A and B are made of steel, and the glass, not less than 26mm, is composite insulation fireproof glass. Monolithic fireproof glass window is neither B fire proof window nor A fire proof window, but non insulated fire proof window.
- Q:What are the commonly used admixture for alumina-magnesia refractory? What are the impacts on its performance?
- 2, form Mg-SiO2 coagulation and combination, CA cement bond? Bricks can generally be made by combing with phenolic resin, castable use 1, combined with silicon powder; 3, can also combined with brine MgCl is binding agent
