First, ceramic fiber paper applicationWhen it comes to ceramic fiber paper, I believe that the glass industry, denitrification catalyst industry friends are no strangers,JQ ceramic fiber paper is often used as high temperature insulation gasket, stripping paper, etc. However, some household appliances, automobiles, analytical instruments and other civilian, light industry friends have also found the benefits of HLGX ceramic fiber paper: Thin, soft, tough, high temperature resistance, but also heat insulation, but because of its smoke can not be easily used. It is the existence of ceramic fiber paper binder that makes some users have such doubts.
Second, what is the composition of ceramic fiber paper binder? Will it affect heat treatment parts? Ceramic fiber paper has good performance, because the inorganic fiber itself is not binding, so often need to use adhesives. The organic adhesives used in ceramic fiber paper are acrylic resin, polyurethane emulsion, polyvinyl acetate, acrylonitrile and butyl acrylate polymer, polyvinyl alcohol, etc. These organic materials will produce unpleasant gases when used at high temperatures, reduce the quality of paper, etc., so also use colloidal silicon, sodium silicate, molybdenum phosphate and other inorganic adhesives. Ceramic fiber paper organic binder will be ablated in the process of high temperature use. JQ ceramic fiber paper is made of high purity ceramic fiber cotton production, organic binder and inorganic binder combined for high temperature insulation field, advanced production technology makes the fiber distribution is very uniform, paper thickness and volume density can also be strictly controlled. Ceramic fiber paper organic matter at 300℃-900℃ can occur high temperature oxidation gradually volatilized, accompanied by slight smoke, volatilized fiber paper toughness and strength decreased, brittleness increased, but will not affect the insulation effect. It is recommended that electric ovens, microwave ovens and other food appliances should first cut ceramic fiber paper into the size and shape used, and perform inorganic treatment before installation and use to eliminate organic matter. Other industrial heat treatment furnaces can ignore the impact of organic matter and use directly; With high environmental requirements, the empty furnace can be preheated to 600℃ for 6h before processing the workpiece to eliminate organic matter and then used to prevent smoke pollution to the workpiece.
Third, ceramic fiber paper types:Standard ceramic fiber paper JQ-236, use temperature below 1000℃, thickness 0.5/1/2/3/4/5/6/8/10mmHigh aluminum ceramic fiber paper JQ-436, service temperature below 1100℃, thickness 2/3/4/5/6/8/10mmZirconium ceramic fiber paper JQ-536, use temperature below 1200℃, thickness 2/3/4/5/6/8/10mm
