- Q: Does anyone know the characteristics of refractory for glass kiln?
- The characteristics of refractory for glass kiln: First, it can well resist the erosion of glass?fusant and gas actor, and has sufficiently high load softening temperature and thermal stability. Usually we hope the refractories of all parts of the furnace will has no partial early erosion phenomenon to ensure that the entire furnace has a sufficiently long service life. However, due to the different mechanical, physical and chemical conditions of different parts of glass furnace, the performance of refractories should adapt to the glass furnace thereto and at the same time has no adverse effect on the adjacent other kinds of brick materials. Besides, we should consider the price of brick material, we should try to consider using commonly used stereotypes bricks of standard sizes which is cheap and quickly supplied by the warehouse. The damage of glass melting furnace lining is mainly due to chemical erosion, assisted by thermal stress. The degree and speed of chemical erosion is closely related to the applied parts, furnace temperature and melting glass varieties, and of course, the quality of the lining itself is also crucial. The nature of refractories using in the glass furnace has a very significant impact on the operation of glass melting furnace and the quality of glass. The application of poor main beam refractories will not only cause frequent shutdown for maintenance, limiting melting temperature, lowering furnace output, but also shorten the life of the furnace, and make glass has a variety of defects (stripes, stones, etc.), lower the quality of the glass. Here are the description of the nature and purpose of commonly used refractory in glass furnace.
- Q: How to distinguish the fire resistant level of the rubber and plastic thermal insulation material?
- Fire?rating grading of external wall thermal insulation materials. 1, China's national standard GB8624-97 divides the combustion performance of building materials external insulation materials into the following grades. Level A: Incombustible materials: Almost no burning materials. Level B1: Incombustible materials: Flame-like material has good fire-retardant effect. In case of fire in the air or at high temperature, it is difficult to fire and doesn't spread quickly, and when the fire source is removed after combustion, it stops immediately. Level B2: Incombustible materials: Combustible materials have a certain flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily leads to the spread of fire, such as poles, wooden frame, wooden beams and wooden stairs,ect. Level B3 : Incombustible materials: No flame-retardant effect, hidhly flammable and high fire risk. 2, The external wall thermal insulation materials could be divided according to the fire?rating. 1) thermal insulation material that has the level A combustion performance: Spraying inorganic fiber, glass wool, foam glass, ceramic foam, rock wool, foam cement and perlite obturator, and so on. 2), The thermal insulation material that has level B1 combustion performance: Special processed extruded polystyrene board (XPS) / special processed polyurethane (PU), phenolic and polystyrene powder. 3), Thermal insulation materials that have level B2 combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
- Q: what's the varieties of fire-proof?sealing?material?
- ATD-AB, organic fire-proof caulking, fire retardant bag, fire retardant net, fire retardant ring, fire barrier wrap, fireproofing sealing strip, flexibility fireproofing coiled material, fireproof glue, etc., fireproofing sealing materials currently on the market can be divided into two types, one is the traditional type: flexible organic caulking, WXY-II, fire retardant bag, fire?bulkhead, cable refractory coating; there are some new materials used in large-scale projects: fireproofing coating board system (fireproofing coating board, intumescent fireproof sealing tape, elastic fireproof sealant, Waterborne Fire-retardant Coating), fire retardant module system (fire retardant module, sealing gum, cable refractory coating), fireproofing plaster system (fireproofing plaster, sealing gum, cable refractory coating).
- Q: Is there requirement for radiation indicator in refractory?
- All refractories have no radiated harm to environment, so there is no requirement. From the elemental analysis, magnesite. I do not know it is helpful to you. But for refractory rwa material, any chemical element is radiated, including silicon?dioxide; If they are radioactive. From the use analysis, such as bauxite, do not have use value.
- Q: what's the fire endurance of fireproof?panel?
- fire endurance of fireproof?panel generally is 3 hours. For example, 12 mm non-asbestos fiber reinforced calcium silicate board, fireproof?panel, two single 75 keel. through the monitoring of national fireproof construction materials quality supervision center, it's security and refractory time will reach over 3 hours. fireproof?panel, also called fire resistance board, scientific name is thermosetting resin impregnated paper laminated wood,english abbreviation HPL(Decorative High - pressure Laminate) is fire resistant building material for surface decoration and has rich surface colors,lines and special logistics performance, it's widely used in interior decoration, furniture, cabinets, laboratory table, external wall, etc.
- Q: What are included in fireproofing materials?
- Incombustible?material of construction fire-proof material Grade A: Cement, stone, steel, coat, glass, aluminium alloy, ceramic tile, etc.; nonflammable material Grade B1: Fireproof?panel, rock wool.
- Q: Which brand of AAA refractory is good?
- Foshan Nanhai Yanbu Shuying fire-resistant insulation material is very good, and it is a professional company of the production and sale of refractories. Our company specializes in the production of refractory bricks, refractory bricks, refractory castable, refractory aggregate, refractory materials, bauxite, alumina bricks and to undertake the production of various common refractory bricks and non-sizing bricks. The Zhengzhou Fire High Temperature Materials Co., Ltd. is also a good company. It is a collection of R & D and production company. The company mainly produces refractories, refractory bricks, refractory castable, refractory aggregate, refractory materials, special refractory bricks.
- Q: Which brand of refractory fiber hard thermal insulation board is better?
- Luyang ceramic fiber semi-hard board is good for it has typically applied major technological performance industrial furnaces backing, wall lining, lining material, electric heating furnace backing lining heat insulation ceramics shuttle kiln, backing lining of tunnel kilnand roller kiln.
- Q: How to choose the material of refractory?
- Long using temperature of aluminum oxide fiber is 1400 ℃, containing chromium aluminum silicate fiber, quartz, high purity aluminum silicate fiber, long-term use of temperature is 1000-1200 ℃ has aluminum silicate refractory fiber according to different raw materials, advanced refractory fiber (such as alumina. Commonly used vitreous aluminum silicate refractory fibre is amorphous, zirconium oxide refractory fibre) using temperature is 1700 ℃ view as >and the best temperature is 1300 ℃. Crystalline refractory fiber are polycrystalline mullite fiber, including ordinary aluminum silicate fiber, alumina and graphite refractory fiber, etc. The use of common refractory fiber temperature is 1150 ℃;>
- Q: What are the best refractory materials in 2,400 Celsius degree?
- It is the purpose that decides what kind of materials you should use. What you have said is 2,400 Celsius degree, right? It is about the fire resistance of the material or the required temperature of it?
