Q:What's the function of ceramic fiber rope?
It can be widely applied in industries such as electric power, papermaking, food, pharmacy, etc. and the sealing of boiler door, machine, pump and valve with high temperature and high pressure. It is suitable for medium such as clean liquid or slurry, salt water, emulsion, grease, hydrocarbon, solvent, pulp, etc.
Q:Ceramic fiber blanket will not expand when heated?
HLGX ceramic fiber blanket itself is composed of many micron diameter ceramic fiber perplexing interweaved, i.e. HLGX ceramic fiber blanket, whether it is the standard grade HLGX-212, grade HLGX-512 or containing zirconium maximum temperature of 1400 DEG C, they are porous materials with high porosity is more than 90%, so hot after contracting Huolong ceramic fiber blanket heating or expansion will be the equivalent pore off, will not be too obvious. This is from an experimental point of view.
Q:What kind of garbage does the ceramic fiber cotton belong to?
Ceramic fiber loose cotton is a kind of fluid which can melt high purity clay clinker, alumina powder, silica powder, chrome sand and so on in the industrial electric furnace.
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 is nano ceramic fiber board?
Ceramic fiber usually makes inorganic material into threadiness, and is used for refractory material or other filling material. The nano ceramic fiber board that you said is generally powder particle on the nanoscale, then made into ceramic fiber.
Q:What is the 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 industries as machinery, metallurgy, chemical industry, petroleum, ceramic, glass, electronics, etc.
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: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.
Q:What’s the use of ceramic fiber resistance furnace?
It’s widely applied to all sorts of industrial furnaces, steel ladles, foundry ladles, submerged nozzle high temperature thermal insulation materials, electric and thermal insulation materials of industrial furnaces, furnace doors, sealing materials of furnace body’s expansion joints, liners of cast aluminum models, demoulding of glass ceramics and hot-melt glass, high temperature sealing gaskets, thermal and electrical insulation materials of heating equipment, mufflers and exhaust pipes of motors, 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.
