  • Ceramic fiber blanket is manufactured from refractory ceramic fibres, providing effective solutions to a wide range of thermal management problems. Utilizing our proprietary high output blowing and spinning techniques, these products supply superior insulating performance, flexibility and resilience.

  • Ceramic fiber blanket presents unparalleled refractories and thermal insulation due to its long spun fiber needling technique,these blankets offer superior insulating performance,flexibility    and  resilience.Ceramic fiber blanket products are unaffected by most chemicals(except hydrofluoric and phosphoric acids and concentrated alkali).Thermal and physical properties are retained after drying following wetting by oil,steam or water.Ceramic fiber blanket products are completely inorganic,so there are no fumes when heating for the first time.

Q:What are the specifications of ceramic fiber thermal insulation pipe?
Technical performance unit: Kg/m technical capacity: 345-60 heat conductivity coefficient: W/m.k0.016-0.024 using temperature: -90-+120℃
Q:What are the specifications of ceramic fiber rope?
Product name of ceramic fiber rope: ceramic fiber packing and ceramic fiber rope(It is divided into ceramic fiber twisted rope, ceramic fiber woven rope, ceramic fiber square braided rope, ceramic fiber circular knitting, ceramic fiber loose rope, ceramic fiber cable rope of three strands, flat ceramic fiber packing, flat ceramic fiber square rope, etc.). Metal wire and glass fiber filament are reinforced. Specification: 6-160mm (other specifications can be customized according to specific situations)
Q:What is the performance of ceramic fiber tube furnace?
The performance of ceramic fiber tube furnace is good, mainly used in small volume production and experiments of colleges and universities, scientific research institutions, industrial and mining enterprises. Ceramic fiber tube furnace is safe and reliable, easy to operate, and is of high accuracy of temperature control, good effect of heat insulation, wide range of temperature, high uniformity of furnace temperature, various temperature zones.
Q:Who knows the advantages of the far infrared ceramic fiber?
It is fired under the high temperature, does not fade, non-absorbent, non-deformation and easy to clean. Some ceramics can be used in microwave ovens and are non-toxic and harmless to the human body. Advantage is the combination of beauty and use. The defect is fragile.
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:Who can tell me what ceramic fiber blanket is?
Ceramic fiber is also called aluminum silicate fiber, with aluminum oxide and silicon oxide as its main constituents and other little constituents. According to different constituent proportion and the added ancillary constituent, temperature resistance ranges from 900 to 1700 degree. There is also higher temperature resistance fiber like inorganic fiber. The constituent category is nearly same, but the difference of composition proportion is very big. It has other names in practices.
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:What is the standard of ceramic fiber?
There are no particular standards. The specifications of ceramic fiber products: 5 x 5mm-200 x 200mm; Special specifications or all kinds of non-standard products can be made according to customers’ requirements.
Q:What is the difference of ceramic fiber asbestos cloth?
The main function of ceramic fiber is resistant to fire and high temperature, fireproof, thermal insulation. Its maximum applicable temperature is 1260℃. The general thickness is 1.5-5mm. The width is 1 meter or below the specification. Long-term applicable temperature is 1100℃. Asbestos cloth is used as binding up thermal insulation material for various equipment and heat conductivity system. Asbestos cloth is interweaved with quality asbestos yarn and applicable to thermal insulation equipment as heat insulation material or can be made into other asbestos products.
Q:Does anybody know about the property and application of the ceramic fiber heating plate?
Ceramic heater plate is a heater with high heating temperature and long service life. It can adapt to increasingly high requirement on working temperature in modern industries, particularly the chemical industry, chemical fiber, engineering plastics, plastic machinery, electronics, medicine, food and various pipelines. Ceramic heater is formed by putting screw-type resistance wire through specially designed high temperature resistant ceramic tile and extending it precisely. It is flexible with beautiful metal shell ceramic fiber as the insulating layer, forming effective high temperature and high power density. It is a heater with band form, flexible design and easy installation. Element structure of ceramic heating plate (far-infrared heating plate, embedded ceramic heating plate): Adopting high radiance glaze and ceramic material with good thermal shock performance as base material, ceramic heating plate is sintered at a time with high-quality nichrome wire.
