Q:What is the difference between the national standards for ceramic fiber products and ordinary aluminium silicate?
Ceramic fiber products (aluminum silicate fiber products) in recent years, ceramic fiber products (aluminum silicate fiber products) in the application of high temperature sintering furnace expanding, ceramic fiber products (aluminum silicate fiber products) refractory felt and blanket products, the highest use temperature up to 1649 DEG C. Ceramic fiber products (aluminum silicate fiber products) to heat insulation effect is good, easy to use, especially small heat storage characteristics, widely used in various kilns, greatly demonstrated high energy efficiency. Ceramic fiber products (aluminum silicate fiber products) (1) ceramic fiber products (aluminum silicate fiber products) varieties and properties of ceramic fiber products (aluminum silicate fiber products) is the most important indicator of fiber diameter and thermal stability. Al2O3SiO2 fiber is commonly used in ceramic industry. It is divided into different application range according to the content of Al2O3, and Cr2O3 material is introduced into it to improve its refractory and oxidation resistance.
Q:How to choose the right ceramic fiber and aluminum silicate products?
3, according to the thickness of insulation to chooseThere are a lot of insulation thickness of furnace is fixed, the insulation thickness of conventional material is inappropriate, only according to the heat flow calculation formula to calculate the appropriate level of insulation material is the most scientific, the conventional case raised to two of the product can be registered.
Q:The characteristics of ceramic fiber paper
Ceramic fiber paper, aluminum silicate fiber paper, also called refractory fiber paper.Classification of ceramic fiber paper:Standard ceramic fiber paper HLGX-236High alumina ceramic fiber paper HLGX-436Ceramic fiber paper containing zirconium HLGX-536
Q:What ceramic fiber profiled products are needed in steel mills? What's the name?
Ceramic fiber and nano heat insulation board are used for heat insulation, and in the steel plant are generally used for ladle, tundish insulation, and now can also be made of nano insulation products special-shaped products.
Q:Slag ball content of ceramic fiber material?
2800 ~ 3200kg/m the data of fand, right?Chasing the answerThis value is 2800 ~ 3200kg/m fand slag ball density, not ceramic fiber density
Q:Brief introduction of ceramic fiber cloth
General specifications of ceramic fiber cloth: 1.5mm--6mm, average width is 1m, which is divided into (nichrome wire reinforced stainless steel wire reinforced, glass fiber, ceramic fiber coating, ceramic fiber cloth with slag, sintered ceramic fiber cloth, ceramic fiber cloth fumigation) properties of ceramic fiber cloth:High temperature resistance, low thermal conductivity, thermal shock resistance and low heat capacity;Excellent high temperature insulation performance, long service life;With corrosion resistance, aluminum, zinc and other non-ferrous metal erosion capacity;It has good low temperature and high temperature strength;Non-toxic, harmless, no adverse effects on the environment;
Q:What is ceramic fiber paper?
The specification is various, the thickness of 0.5-10mm. products using four consecutive rinsing and slag removal process, the fiber distribution, high tensile strength good flexibility, no delamination, no slag, can be cut with a little organic matter.
Q:What is the use of ceramic fiber paper?
3) good high temperature strength and heat insulation performance (refer to physical and chemical indexes). 4) having a higher level of electrical insulation and high temperature electrical insulation than glass fibers. 5) non-toxic, harmless and odorless.
Q:At present, the field of ceramic fiber, what is the latest development of technology or products?
The latest technology -- Research and development of ceramic fiber composite. HLGX ceramic fiber composite insulation board is a new super insulation material produced by semi dry process, which is the first in the world. The difference between it and imported aerogel composite insulation board is reinforced fiber changes (replaced by glass fiber ceramic fiber), change of substrate and adiabatic main material ratio, and the addition of other nano additives. The promotion point of innovation -- resistance to temperature liftingHighest 800 C to 1000 C, long-term working temperature shrinkage rate decreased from 3% down to 2%, there is a big boost for high temperature applications, only the production process is complicated, the cost is still high.
Q:The product characteristics of ceramic fiber cloth?
Excellent high temperature insulation performance, long service life;With corrosion resistance, aluminum, zinc and other non-ferrous metal erosion capacity;
