Ceramic Fiber Blocks For Thermal Insulation

Q: Which company needs the new refractories?: The power plants are mainly used in steel plant, lime kiln, coking plants, boilers, etc. I will try my best to answer what I can. There are too many glassworks. You can tell me more anout what you need. As long as there is a large kiln business, the refractories and aluminum manufacturer are needed.

Q: Physical and chemical indicators of various refractory.: please read"Refractories Standard Series" for refernece, general business standards are higher than the national standard.

Q: What refractories are accessible with ease in daily life?: Refractory mortar. Thermal insulation refractory materials include diatomite products, refractory castables, monolithic?refractories, carborundum bricks, gun-mix refractories, semi-silica bricks, borides, beryllia, silicide, calcium oxide, high alumina refractory brick, refractory coatings, corundum bricks, fireclay?bricks, silicon nitride bonded silicon carbide bricks, chromium hemitrioxide and other refractories. What refractories can be found mostly in the market? Common refractories. Common refractories include silica bricks. The mostly used unshaped refractories include fettling, ramming refractories, castable refractories, plastic refractories, refractory clay, gun-mix refractory, sling refractories, refractory coatings, lightweight refractory castables, stemming etc. The mostly used insulating refractories include diatomite products, asbestos products, insulation panels, etc. The mostly used special refractories include AZS bricks.

Q: what is the requirements of roofing insulation materials fire rating?: The fireproofing requirements of architectural design are regulated by architectural design fire?safety?rules, roofing insulation material only has the requirements of materials combustion performance, namely non-combustible material. No fire rating requirements.

Q: What are the insulation fireproofing materials?: Asbestos is the most common. Asbestos containing zirconium and made of the mixture of zirconium aluminum and silicon through wire drawing is better. Of course, some are made directly from natural things which can withstand 1400 degrees for over 30 seconds while the internal temperature had no significant change, and withstand 1400 degrees for over five minutes while inside temperature increase does not exceed 5 degrees.

Q: Using what kind of melting aluminium furnace refractories is more appropriate?: If it's the ordinary, you can use high aluminum refractory brick with general clay, GB/T 3994-2005 clay heat insulation refractory brick. If you need these with good material, there is high alumina thermal insulation refractory brick, GB/T 3995-2006 high aluminum heat insulation refractory brick, models have A13 and material is the alumina, A13 50 u, high insulating brick B5.Intermediate insulating brick B2, etc. Dolomite brick: good hang kiln performance, good erosion resistance, but brick is usually without f - CaO, hydration, and difficult to transport and storage, less used in the production. Magnesia-chrome bricks: good hang kiln, used in calcining zone. The disadvantage is that its thermal shock resistance is poor and plus hexavalent Cr is toxic, the production and use of magnesite chrome bricks in international countries gradually reduce. Now unit using the brick find replacements as soon as possible.

Q: Who knows the external wall thermal insulation materials fire rating requirements?: 1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 Level A insulation material is only for fireproofing, but its thermal insulation performance is not better than organic XPS \\ EPS and other materials. I feel the best insulation materials should be modified phenolic board, which can keep insulation and fireproofing, but the unit price is very expensive. Insulation materials in the domestic market have some disadvantages, it is better to considere the materials within the acceptable range in the building needs.

Q: The principle of choosing fire-resistant material in Thermal Energy and Power Engineering equipment.: What thermal equipment? The most simple principle is durable, low cost and with no environmental pollution.

Q: Who knows how many poured refactory material are there?: Pouring refractory material can be classified into the followings according to the body density: Heavy (> 2.0g\cm3), medium heavy (1.0-2.0g\cm3), light (0.4-1.0g\cm3); by binding agent: Combination of hydration, chemical binding, condensation, hydration and condensation: Clay, high alumina, silica, magnesia, alumina magnesia, magnesium and chromium, magnesium zirconium, silicon carbide etc.. Clay brick, high alumina brick, bead brick, silica brick, light mullite, alumina hollow spherical brick, oxidation zirconium hollow spherical brick, corundum brick, magnesia brick, magnesia brick, magnesia alumina spinel brick, magnesia chrome brick and so on

Q: What refractory materials are used in power plant: Vacuum mud machine, sintering furnace! And then I will introduce some application of thermal material in power plant (below) I hope I can help you. Energy saving is the trend of future industrial development efforts, grinding machine, conveyor belt, so the production of light thermal insulation materials will gain state support, drying kiln. Our factory mainly produce light thermal insulation brick. The refractory material we use most is light insulation brick, and the equipment used is sand mixer (Luohe, Henan)
