Q:How is the quality of ceramic fiber vermiculite cloth?
The quality of ceramic fiber vermiculite cloth is good, and its advantages are as follows: high temperature resistance, low thermal conductivity, thermal shock resistance, low thermal capacity; excellent heat insulation performance, long service life; resistant to erosion of nonferrous metals such as aluminum and zinc, etc.; good low and high temperature strength; non-toxic, harmless, and no adverse effect on environment.
Q:What’s the principle of ceramic fiber casing production?
Mainly referring to the traditional textile production process, and by spinning the aluminum silicate refractory fiber into yarn, using the glass fiber or heat-resistant steel wire as reinforced material, adopting special textile technology and equipment, ceramic fiber casing is thus braided. 1. It is a sort of new thermal insulation refractory and inorganic material. It can be permanently used at high temperature of 1000℃. Containing a certain amount of adhesive material, it is usually burned at lower temperature with no effect on its insulating property. It keeps good mechanical strength even after heating. 2. Ceramic fiber casing has the characteristics of light weight, high temperature resistance, thermal insulation, acid and alkali resistance, innocuity, higher tensile strength and good toughness. 3. Compared with glass fiber sleeve, it has superior electrical insulating property even under high temperature conditions. 4. Ceramic fiber casing possesses good dielectric property, chemical resistance, excellent flexibility and elasticity.
Q:What is the performance of ceramic fiber tube furnace?
It is a kind of high temperature experiment equipment, adopting quality and super energy-conservation ceramic fiber tank. It is highly energy-conservation, and its energy consumption is only a half of ordinary tube furnace. High temperature electric resistance wire warms up, and the insulation layer is fiber cotton blanket and metal shell. Quartz tube and sealing equipment can be chosen according to different requirements, and can be vacuumized or connected to air. It includes various types: tube furnace, tube furnace of multiple temperature zones, tube-typed heating furnace, tube-typed resistance furnace, high temperature tube… 6、Owing to perfect insulation performance and low heat capacity, the whole equipment and ordinary heavy refractory furnace
Q:What is the thickness of ceramic fiber paper?
The thinnest ceramic fiber paper is 0.5mm. Ceramic fiber paper can be used as high temperature thermal insulation material for various industrial furnaces, steel ladles, foundry ladles as well as submerged nozzles, as electric and thermal insulation material for industrial furnaces, as sealing material for expansion joint of furnace door and body, as lining of cast aluminum model, as demoulding glass ceramics and hot-melt glass, as high temperature sealing gasket, as thermal and electric insulation material for heating equipment of apparatus, as noise elimination as well as thermal insulation material for muffler, and as thermal insulation material for exhaust pipe, etc.
Q:What degree can the high temperature ceramic fiber paper tolerate?
The products of aluminum silicate ceramic fiber paper are divided into four level temperature, namely 1000℃ ordinary type, 1260℃ standard type, 1360℃ high alumina type and 1450℃ zirconium containing type. These are the maximum temperature resistance, not daily operating temperature. Daily operating temperature should be lower than the maximum temperature resistance.
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 is the price of ceramic fiber fire-resistant cloth?
The common specification and model of ceramic fiber cloth: 1.5-6mm, general thickness: 1m, including nickel chromium alloy wire reinforced, stainless steel wire reinforced, glass fiber reinforced, ceramic fiber coating cloth, ceramic fiber slag cloth, ceramic fiber sintering cloth, ceramic fiber fumigation cloth. The price of ceramic fiber fireproof cloth is 5 yuan/m2.
Q:What’s soluble ceramic fiber?
It’s alkali earth ceramic fiber with main components of SiO2, MgO, and CaO. With certain solubility in the human body fluid to be less harmful to human health, it is called soluble ceramic fiber. The introduction of such components as MgO, CaO, etc. in the soluble ceramic fiber, on one hand, is conducive to extending the viscosity range of and conditions for the fiber forming, enhancing the chance of fiber forming and the flexibility of fibers. On the other hand, it produces low melting compounds like CaO•SiO2, CaO ·Mgo·2SiO2 etc, decreasing the heat resistance of the fiber. Therefore, the ordinary soluble fiber belongs to inferior ceramic fiber, and its product is mainly used as backing material for the industrial furnace. To realize the improvement of heat resistance of soluble fiber, the method of adding ZrO2 into it is adopted, increasing the viscosity of glass phase and inhibiting the growth rate of grains after the fiber is heated and crystallized.
Q:What’s the difference between the ceramic fiber and glass fiber?
Both of them are inorganic nonmetallic material and silicate. They can be used as structural material focusing on mechanical properties and functional material focusing on characteristics of light, electricity, sound and magnet, etc. Their main difference lies in the operating temperature: the glass wool is less than 300℃, while the ceramic fiber can reach up to 1000℃.
Q:What’s the difference between heat preservation and heat insulation ceramic fiber blanket and rock wool blanket?
The difference between heat preservation and heat insulation ceramic fiber blanket and rock wool blanket: refractory ceramic fiber material is a kind of lightweight and efficient heat preservation and heat insulation material. Its advantages are as follows: the volume and density of ceramic fiber as lining are low. Ceramic fiber lining is 75% lighter than lightweight insulating brick lining and 90%-95% lighter than lightweight castable lining. If fiber lining is adopted, steel structure load of furnace can be greatly reduced and the service life of the furnace can be prolonged. Heat capacity (heat storage) of ceramic fiber as lining is low: Heat capacity of ceramic fiber is about 1/10 that of lightweight and heat resistant lining and lightweight castable lining. Heat capacity of furnace lining material is proportional to the weight of the furnace lining. Low thermal capacity means that furnace absorbs less heat in the reciprocating operation and, at the same time, the speed of warming gets faster, which greatly reduces the energy consumption of the furnace temperature operation and control and especially plays a very significant role in energy saving effect in the starting-up and blowing-out of heating furnace. Thermal conductivity of ceramic fiber as lining is low: When the average temperature is 400℃, 600℃ and 1000℃, thermal conductivity coefficient of ceramic fiber as lining is less than 0.1w/mk, 0.15w/mk and 0.25w/mk respectively, which is 1/8 that of lightweight fireclay brick and 1/10 that of lightweight and heat resistant lining. Ceramic fiber as lining has prominent insulation performance. Ceramic fiber as lining is easy to construct: Expansion gap is not needed during the construction process. Construction personnel can start to work after basic training and construction technology has little effect on the heat insulation effect of lining.
