Q:What is the standard of ceramic fiber?
The standard of ceramic fiber: Temperature classification: ordinary aluminum silicate fiber board 1100℃, standard aluminum silicate fiber board 1260℃, high purity aluminum silicate fiber board 1260℃, high alumina aluminum silicate fiber board 1360℃ and zirconium containing aluminum silicate fiber board 1430℃.
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:What is the difference of ceramic fiber asbestos cloth?
Ceramic fiber cloth is resistant to high temperature and heat shock, low in heat conductivity coefficient and heat capacity; excellent high temperature insulation performance and long service life; able to resist the erosion of non-ferrous metal like aluminum and zinc; excellent low and high temperature strength. It is made from asbestos cotton. Owing to its noninflammability, once on fire, it can erase dirt on the cloth.
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:What is the raw material of ceramic fiber?
Ceramic fiber is a fibrous and light fireproof material with such advantages as light weight, resistance to high temperature, good heat stability, low thermal conductivity and specific heat, resistance to mechanical shock, etc., thus being widely used in such industry as machinery, metallurgy, chemical industry, petroleum, ceramic, glass, electronics, etc. Besides the good quality of fibrous ceramic fiber cotton, the product made out of ceramic fiber board is very hard and resistant to wind erosion. Ceramic fiber backing board is light, easy to work, and it won’t expand after being heated. It can be sheared and curved optionally. Thus, it is an ideal energy-conservation material for furnace, pipeline, and other thermal insulation equipment. The application of making ceramic fiber modules: Thread throwing blanket is better than injection blanket because of its thick and long fiber. In the folding process of making modules, injection fiber blanket is easy to break up and tear up while thread throwing fiber blanket can be folded tightly and not easy to break up. The quality of modules will directly affect the quality of furnace lining.
Q:What is the difference between nanometer ceramic board and ceramic fiber board?
The difference between nanometer ceramic fiber board and ceramic fiber board is as follows: The traditional ceramic fiber board with good heat insulation and high temperature resistance is widely applied in some furnaces, but some deficiencies, such as low strength, still exist in this kind of traditional products, which restricts its application in furnaces with high temperature, high pressure and stress. However, product performance is greatly improved with the introduction of nanotechnology and the use of special manufacturing technique. It has high strength, low thermal conductivity, good thermal insulation performance, obvious energy saving effect, which can improve the safety of furnace and develop performance of the product under the condition of high temperature and high pressure.
Q:Is high density ceramic fiber board environmentally friendly?
As far as I know, high density ceramic fiber board is environmentally friendly. For it is a kind of plate pressed by the raw material of ceramics and other plant fibers combining urea formaldehyde resin or other synthetic resins under the conditions of heat with pressure, it is more natural and environmental.
Q:What high temperature can the refractory ceramic fiber cloth tolerate?
It depends on what material used in the ceramic fiber. The normal operating temperature of aluminum oxide is 1200 degree. This is residential. It has 2200 degree high temperature in military.
Q:What are the specifications and models of the ceramic fiber board?
It’s refractory material and can keep good mechanical strength even after heating. Compared with fiber blankets and felts, it is thermal insulation product with rigidity and supporting strength. Its making principle adopts injection fiber (which is short, fine, and easy to smash).
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.
