Q:Who can tell me what the ceramic fiber density is?
Refractory ceramic fiber material, a kind of light and efficient thermal insulation material, owns the following advantages compared with traditional thermal insulating material: Ceramic fiber lining has low volume density. It is over 75%lighter than the light weight insulating brick, and 90%-95% lighter than the light weight castable lining. If fiber lining is used, the steel structure load of furnaces can be greatly reduced and its service life will be prolonged. Ceramic fiber lining has low thermal capacity which is only about l/10 of that of the light weight and heat resistant lining and light weight castable lining. The thermal capacity of the lining material is proportional to its mass. Low thermal capacity means that furnaces absorb less heat in the reciprocating operation, meanwhile accelerate its temperature rise, greatly reducing energy consumption during the operation and control of the furnace temperature, and particularly making the starting-up and blowing-out of heating furnaces obtain remarkable energy conservation effect. Ceramic fiber lining has low thermal conductivity. When the average temperature is 400℃, its thermal conductivity coefficient is less than 0.1w/mk; when the average temperature is 600℃, its thermal conductivity coefficient is less than 0.15w/mk; when it is 1000℃, the thermal conductivity coefficient is less than 0.25w/mk, which is around l/8 of that of the light clay brick and l/10 of that of the lightweight and heat resistant lining, achieving excellent thermal insulation effect. Ceramic fiber lining has easy construction. Expansion joints are not needed during the construction process, construction personnel can take up work right after basic training, and the construction technical factors have little impact on the lining’s thermal insulation performance.
Q:What kind of thermal insulation material is the grade of combustion performance?
Combustion performance grade a class of thermal insulation materials, HLGX glass fiber felt, dragon flame ceramic fiber blanket, fire dragon ceramic fiber module.
Q:What should be done on the surface of refractory ceramic lining when building unshaped refractory material?
The castable of refractory castable is made on the ceramic fiber board. Ji'nan dragon hot Ceramic Co., Ltd. (Dragon Fire energy) in the insulation layer, will be the insulation material cutting, to ensure no gaps.
Q:Is there any difference between ceramic silicon fiber board and ceramic fiber board?
Ceramic fiber board is aluminum silicate fiber board, a refractory material. Even after heating, good mechanical strength is maintained. The product is a fibrous insulation product that is rigid and has a supporting strength compared to fiber blankets. Features: ceramic fiber board has excellent quality, toughness and strength, besides, it has excellent resistance to wind erosion. The utility model has the advantages of no heat expansion, light weight, convenient construction, and arbitrary shearing and bending. The utility model is an ideal energy-saving material for kilns, pipes and other heat preservation equipment.
Q:What's the function of ceramic fiber rope?
It can be widely applied in industries such as electric power, papermaking, food, pharmacy, etc. and the sealing of boiler door, machine, pump and valve with high temperature and high pressure. It is suitable for medium such as clean liquid or slurry, salt water, emulsion, grease, hydrocarbon, solvent, pulp, etc.
Q:What is the feature of ceramic fiber gasket?
This product belongs to non-brittle material with high strength, accurate size, and good fireproofing &insulation effect. It can be multi-shaped according to the requirements of customers. And it can touch fire directly. Classified temperature is 1050-1600℃. tough texture and resistance to wind erosion no-gap furnace lining low heat storage and heat loss touch fire directly fine construction and installation excellent resistance to heat shock high compressive strength and long service life effective sound absorption
Q:Ceramic fiber material fire shutter door how many square?
If the above two kinds of roller blinds, really true to do, the former per square meter at least 500 yuan, and the latter at least 400 yuan per square meter. Otherwise, there must be a problem.
Q:Ceramic fiber blanket afraid of water?
Hydrophobic ceramic fiber blanket is non absorbent, and if you use ceramic fiber blanket in water environment, it is recommended to use hydrophobic ceramic fiber blanket, do not use conventional ceramic fiber blanket.
Q:Is ceramic fiber cotton block poisonous?
The dust produced by ceramic fiber cotton block is harmful to body, mainly presented as respiratory symptom, skin and eye irritation symptom, lung function reduction, obvious change of chest radiograph abnormities.
Q:Should the ceramic fiber furnace be compacted?
In view of the large industrial furnace, the ceramic fiber module can be chosen to be refractory, heat insulated and insulated, and the ceramic fiber module is firmly fixed on the furnace wall by the parallel mounting method, which is more reliable
