Q:What’s the use of ceramic fiber resistance furnace?
The series of box muffle maximum working temperature can be up to 1200℃, and it can be used in the field of laboratory rooms, industrial and mining enterprises, and research and development institutions for elemental analysis and determination, quenching, annealing, and tempering of the small-sized steel.
Q:How is the ceramic fiber cotton performance?
It has white color and precise size, is easy to cut, stall and construct, saves time, does not contain any binder. It is used in sound-absorbing and fireproof performance automation production with low thermal capacity, low thermal conductivity, high refractoriness, high heat sensitive, excellent wind erosion resistance and excellent mechanical shock resistance under the neutral and oxidizing atmosphere. It has stable density and performance.
Q:What is the feature of ceramic fiber gasket?
Ceramic fiber gasket is a fibrous and light material with such advantages as light weight, resistance to high temperature, good heat stability, low thermal conductivity coefficient and specific heat, resistance to mechanical shock, etc.
Q:What’s the maximum bearing temperature of the refractory and high temperature resistant ceramic fiber cotton?
It depends on what material the ceramic fiber gasket uses. It’s usually referred to high temperature gasket made from ceramic fiber paper. It is generally classified into normalized form and high alumina type, of which the former can resist the maximum temperature of 1260℃ and its continuous use temperature is 1000℃, the latter can be used for a long period at the temperature of 1200℃. Nichrome wire, stainless steel wire and glass fiber are reinforced. Ceramic fiber coating cloth and slag cloth, sintering ceramic fiber cloth and ceramic fiber fumigation cloth) Characteristics of the ceramic fiber cloth: high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment.
Q:What is the raw material of ceramic fiber?
With unique optical property, ceramic material can be used as solid state laser, optical fiber and optical memory. Transparent ceramics can be used for high pressure sodium lamp tube. Magnetic ceramics (ferrite: MgFe2O4、CuFe2O4、Fe3O4 ) will be widely used in audiotapes, records, transformer core and memory elements of large computers.
Q:How to keep ceramic fiber board?
Ceramic fiber board is rigid and high temperature resistant ceramic fiber board, using injection fiber as the raw material of ceramic fiber board and adding a definite proportion of the binder and packing grade additives. It is fully dispersed into paste in the mud pits through beater. It is pumped into the forming pool and stirred by using compressed air. It is made by putting mould into the forming pool and making the fiber pulp adsorbed on the mould by using the principle of vacuum. Ceramic fiber board is characterized by low thermal conductivity, good high temperature stability, resistance to air flow scouring, uniform density, excellent thermal shock resistance, excellent chemical erosion resistance( except phosphoric acid, hydrofluoric acid and strong alkali) and easy installation. It has good heat insulation capacity, which contributes to reducing the energy cost and cycle time and protects the furnace shell from the influence of heat shocks. It can also be directly used as refractory materials.
Q:What’s the difference between heat preservation and heat insulation ceramic fiber blanket and rock wool blanket?
Ceramic fiber strip 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. Ceramic fiber strip, one of fire-resistant and fireproof materials, is produced by the refractory fiber of high purity and applied in high temperature insulation. Compared with natural cellulosic fiber, the characteristics of raw material of glass fiber strip are as follows: circular cross profile, same diameter, highly elaborate production, high proportion of glass fiber and strong dimensional stability.
Q:What is the feature of ceramic fiber washer?
Product features: ※ 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 The application of products: Observing hole of industrial furnace and inserting hole of thermometer ※ Industrial kiln burner and furnace door ※ Non-ferrous metal melting trench, tank gasket and casting cap mouth ※ Mechanical and electrical equipment connected gasket
Q:What's the function of high temperature ceramic fiber blanket?
It is light in quality, good in heat insulation performance, thermal stability and chemical stability, easy to process and convenient in construction. It is neither wear-resisting nor resistant to impact. It cannot resist scouring of high speed air flow and the erosion of slag.
Q:Is ceramic fiber cotton block poisonous?
Ceramic fiber cotton block is non-toxic in that once being fired in high temperature, figuline is safety as long as it is not collected in areas of high heavy metal and high radiation. However, before being fired, some ceramic would be painted with chemical material, which is unsafe to some extent. So you’d better buy white ceramic.
