Q:What is the price of high alumina ceramic fiber cotton?
Refractory ceramic fiber jilt silk rug is 4,000 yuan/kg; ceramic fiber insulation refractory module is 4,700 yuan/kg; ceramic fiber refractory insulation board is 7,000 yuan/kg.
Q:What is the difference between nanometer ceramic board and ceramic fiber board?
Ceramic silicon fiber board, made by burning long fiber silicon dioxide, clay, talcum powder and colored glaze under 1150 degree, is a revolutionary high-tech building material in the 21st century. Ceramic fiber board, also called aluminum silicate fiber board, is a kind of refractory material. It still keeps good mechanical strength even after heating. Compared with fiber blanket and fiber felt, it is rigid and a fiber thermal insulation product with supporting strength.
Q:What industries is ceramic fiber material applicable to?
Ceramic fiber material is applicable to the following industries: 1. Electrical equipment industry: wood-burning stoves, electric and heat insulation materials of electrical heating equipment, and sealing gaskets of all sorts of electrical components; 2. Glass and ceramic industries: industrial furnaces, the furnace body sealing, and molten and hot bending glass demoulding; 3. Petrochemical industry: thermal insulation of transmission lines and high-temperature pipelines. All these industries need to use the ceramic fiber material.
Q:Who can tell me what the ceramic fiber density is?
Refractory ceramic fiber material, a kind of light and efficient thermal insulation material, owns the following advantages compared with traditional thermal insulating material: Ceramic fiber lining has low volume density. It is over 75%lighter than the light weight insulating brick, and 90%-95% lighter than the light weight castable lining. If fiber lining is used, the steel structure load of furnaces can be greatly reduced and its service life will be prolonged. Ceramic fiber lining has low thermal capacity which is only about l/10 of that of the light weight and heat resistant lining and light weight castable lining. The thermal capacity of the lining material is proportional to its mass. Low thermal capacity means that furnaces absorb less heat in the reciprocating operation, meanwhile accelerate its temperature rise, greatly reducing energy consumption during the operation and control of the furnace temperature, and particularly making the starting-up and blowing-out of heating furnaces obtain remarkable energy conservation effect. Ceramic fiber lining has low thermal conductivity. When the average temperature is 400℃, its thermal conductivity coefficient is less than 0.1w/mk; when the average temperature is 600℃, its thermal conductivity coefficient is less than 0.15w/mk; when it is 1000℃, the thermal conductivity coefficient is less than 0.25w/mk, which is around l/8 of that of the light clay brick and l/10 of that of the lightweight and heat resistant lining, achieving excellent thermal insulation effect. Ceramic fiber lining has easy construction. Expansion joints are not needed during the construction process, construction personnel can take up work right after basic training, and the construction technical factors have little impact on the lining’s thermal insulation performance.
Q:What is the use of ceramic fiber rope?
Ceramic fiber loose cotton is made through such a process: Put highly purified raw materials like chamotte, alumina powder, silica powder, silica powder and zircon in high temperature industrial furnace, melt them to form fluid, then use compressed air to inject or thread throwing centrifuge throw it into threadiness, finally use cotton condenser to form ceramic fiber cotton. And fiber cotton can be further processed into kinds of products, such as fiber blanket, board, paper, cloth, rope, etc. Ceramic fiber is highly thermal insulated with such advantages as light weight, high strength, antioxidation, low thermal conductivity coefficient, good softness, corrosion resistance, low heat capacity, sound absorption, etc.
Q:What are the features of ceramic fiber module?
Ceramic fiber, also called refractory fiber, is a refractory material with the lowest thermal conductivity and the best thermal insulation and energy-saving effect so far except nanometer materials. It is a good industrial furnace lining material with light weight, high heat resistance, good heat preservation effect, easy construction and other advantages. The high heat sensitive of ceramic fiber furnace lining can better adapt to the automatic control of heating furnace. The chemical performance of ceramic fiber lining is stable. Acid, alkali, as well as water, oil, steam are not eroded except phosphoric acid, hydrofluoric acid and strong alkali.
Q:Does anybody know about the property and application of the ceramic fiber heating plate?
First, property and application of ceramic heating plate: It is a heater with high heating temperature and long service life. Ceramic heater 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. Second, technical characteristics: Ceramic electric heater has ring type, plate and other specifications. It possesses many advantages: reliable during work, long service life, sturdy and durable, energy saving, easy installation, high temperature resistant, high heat conductivity, good insulation, and no limitation of models, specifications and dimension in manufacturing. According to users’ demand on mode of connection, voltages of 36V, 110V, 180V, 220V and 380V can be chosen and determined (according to users’ needs). The maximum power termination is 6.5w/m2. Compared with traditional heaters, ceramic electric heater can cut down 30% energy consumption.
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 standard of ceramic fiber board?
Basalt fiber cloth is high-strength and permanent fire resistant. It can endure over 1000℃ in a short period while 760℃ in a long period, which is an ideal material to replace asbestos and glass fiber cloth. Ceramic fiber products use ceramic fiber as raw materials, and boast with such advantages as light weight, resistance to high temperature, good heat stability, low thermal conductivity and specific heat, resistance to mechanical shock, etc., they are used in the environment of high temperature, high pressure and easy abrasion.
Q:What is the standard of ceramic fiber?
Basalt fiber cloth, with high strength, permanent flame retardancy, more than 1000℃ short-term temperature resistance, and used in the 760℃ environment for long time, is the ideal material to replace asbestos and glass fiber cloth. Products of ceramic fiber, made by using ceramic fiber as material, refers to industrial products with light weight, high temperature resistance, good thermal stability, low thermal conductivity, low specific heat and mechanical shock resistance and other advantages. It is exclusively applied in all kinds of high temperature, high pressure and environments where it is easy to wear.
