Q:What is the price of ceramic fiber backing board?
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. Here follows its advantages: 1、high compressive strength and long service life; 2、low heat capacity and conductivity; 3、hardness; 4、accurate size and flatness; 5、easy to be cut and installed; 6、excellent resistance to wind erosion; 7、continuous production, uniform distribution of fiber and stable performance.
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 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’s the price of refractory ceramic fiber blanket?
Ceramic fiber blanket: length x width x thickness x unit weight = weight. The price is different, so is the quality. There are large price differences. It is advised to communicate with others.
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:Does anybody know the specification of ceramic fiber composite material?
Ceramic fiber board LY-264B m3 40.19 Thickness=100mm b L80 Ceramic fiber board LY-264B m3 0.95 Thickness=80mm c L50 Ceramic fiber board LY-264B m3 31.86 Thickness=50mm d L62A Ceramic fiber board LY-164B m3 40.77 Thickness=62mm a L100
Q:Who can tell me what the ceramic fiber density is?
The density of ceramic fiber module is generally within the range of 200-220. The earliest produced ceramic fiber module is made from ceramic fiber injection blanket, for the fiber of injection blanket is fine and short, making the expansiveness of the module made out of it relatively stable. While in recent years, considering the cost of production, most ceramic fiber modules are made from thread throwing blanket for it has large tensile force. Select the density and thickness of the ceramic fiber module according to the furnace body temperature, the thermal state of modules and the thermal atmosphere inside the furnace. If it’s just used as insulating layer, the density of 200kg/m3 is suggested.
Q:What is the feature of ceramic fiber gasket?
1)Continuous use temperature can reach 1000℃ while short time using temperature is up to 1260℃.2) It is highly resistant to acid-base corrosion and erosion of molten metal (eg. aluminum and zinc). 3).It is good in high temperature strength and thermal insulation properties (please refer to physical and chemical indicators.) 4) It is better in electricity insulation than glass fiber. 5) It is non-toxic, harmless and odourless.
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:What’s the difference between the ceramic fiber and glass fiber?
Ceramic fiber strip, a type of fibrous lightweight refractory, possesses so many advantages as light weight, high temperature resistance, good thermal stability, low thermal conductivity, small specific heat and mechanical shock resistance. Therefore it has been widely applied in machinery, metallurgy, chemical engineering, petroleum, porcelain, glass, electronics, and other industries. As a sort of refractory material, ceramic fiber strip is made out of highly purified refractory fiber, and applied in high temperature and thermal insulation field. Compared with natural cellulosic fiber, the raw material of glass fiber tape has the following features: with circular section and the same diameter, glass fiber can be micro fine. It’s higher in specific gravity and more stable in dimension. As a result, the paper made from it by papermaking gains fairly high tensile strength, and excellent properties of water-fast, oil resistance, acid and alkali resistance, corrosion resistance, thermal stability, low thermal conductivity, sound absorption, etc.
