Q:What is the price of ceramic fiber backing board?
Ceramic fiber products use ceramic fiber as raw materials, and boast with such advantages as light weight, resistance to high temperature, good heat stability, low thermal conductivity and specific heat, resistance to mechanical shock, etc., they are used in the environment of high temperature, high pressure and easy abrasion. Ceramic fiber product is a kind of good refractory material with such advantages as light weight, high temperature resistance, low heat capacity, good heat insulation performance, nontoxicity, etc.
Q:What is the feature of ceramic fiber gasket?
Product features: 1)Continuous use temperature can reach 1000℃ while short time using temperature is up to 1260℃.2) It is highly resistant to acid-base corrosion and molten metal (eg. aluminum and zinc) erosion. 3).It is good in high temperature strength and thermal insulation properties (please refer to physical and chemical indicators.) 4) It is better in electricity insulation than glass fiber. 5) It is non-toxic, harmless and odourless.
Q:What is the difference between ceramic fiber insulated cotton and aluminum silicate cotton?
Aluminum silicate cotton is a mineral material, and another name is ceramic fiber thermal insulation cotton. It is mainly because of that the composition of aluminum silicate and ceramics is approximately the same. But in exporting and product classification, they belong to the same refractory material in the essence. One is named by its physical composition while the other is translated according to foreign habit.
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 are the ceramic fiber products?
Ceramic fiber is produced by double needling technique and is widely used in high and low temperature environment. According to the different manufacturing technique used in market, ceramic fiber blanket is usually divided into two kinds. One is thread throwing blanket, and the other is injection fiber. 1. The diameter of the fiber filaments: Thread throwing fiber is much coarser. Thread throwing fiber is generally 3.0-5.0;micro;m; Injection fiber is generally 2.0-3.0;micro;ml. 2. Fiber length: Thread throwing fiber is much longer. Thread throwing fiber is generally 150-250mm. Injection fiber is generally 100-200mm. 3. Coefficient of thermal conductivity: Injection blanket is superior to thread throwing blanket because of its thin fiber. 4. Tensile and flexural strength: Thread throwing blanket is superior to injection blanket because of its coarse fiber. 5. Application of making ceramic fiber block: It is superior to injection blanket because the fiber of thread throwing blanket is much coarser and longer. Injection fiber blanket is easy to be broken and torn during the process of block production folding, while thread throwing fiber blanket can be tightly folded and cannot be easy to damage. The quality of the block will directly affect the quality of the lining. 6. The vertical layer spread application of large pieces of blankets such as heat recovery boiler: Thread throwing blanket has better tensile resistance and is more durable due to its coarse and long fiber filament, so thread throwing blanket is superior to injection blanket.
Q:How is the quality of ceramic fiber vermiculite cloth?
The quality is good. The refractory temperature of ceramic fiber vermiculite cloth is 1200-1450 degree. Ceramic fiber is a kind of fibrous lightweight refractory material with light weight, high temperature resistance, good thermal stability, low thermal conductivity, low specific heat and mechanical shock resistance and other advantages, so it is widely applied in industries such as machinery, metallurgy, chemical engineering, petroleum, ceramics, glass and electronics.
Q:Is high density ceramic fiber board environmentally friendly?
Density board is also called fiberboard. It is artificial plate made from raw material of wood fibers or other plant fibers adding urea formaldehyde resin or other applicable binders. According to the difference of density, it can be classified into three types: high density board, medium density board and low density board. Soft, impact resistant and easy to reprocess, density board is a kind of good material for furniture producing at abroad.
Q:What are the features of ceramic fiber module?
It has good chemical stability; excellent thermal stability and good elasticity. When ceramic fiber module is in a state of prepressing and after the furnace lining is completed, the expansion of the ceramic fiber module makes lining seamless and can compensate the shrinkage of fiber lining so as to improve the heat-insulating performance of fiber lining. The overall performance is good; It possesses excellent thermal stability and thermal shock resistance; Ceramic fiber module is quickly installed. The anchoring parts are set on the cold face of wall lining to reduce the requirements of anchoring parts materials.
Q:Who knows well about the production process of the ceramic fiber?
Ceramic fiber is manufactured by ceramic fiber products undergone accurate clipping, dotting punch, stamping die and other processes (some products are needed to bond by using binders under ultrahigh pressure). Features: 1) Continuous use temperature can reach 1000℃, and short time use temperature can reach up to 1260℃; 2) it’s resistant to acid and alkaline corrosion, and molten metal like aluminum and zinc erosion; 3) It has good high temperature strength and thermal insulation performance (please refer to physical and chemical indicators); 4) It has higher level electrical insulation under high temperature than glass fiber; 5) It is non-toxic, harmless and odorless.
Q:What is the standard of ceramic fiber board?
Ceramic fiber products use ceramic fiber as raw materials, and boast with such advantages as light weight, resistance to high temperature, good heat stability, low thermal conductivity and specific heat, resistance to mechanical shock, etc., they are used in the environment of high temperature, high pressure and easy abrasion.
