Compound filter material is composed of two or more kinds of filter material in accordance with the combination of technological requirements, by chemical, thermal or mechanical methods such as joint compound together, learn from each other through a variety of composite materials was to make up for deficiencies or lack of pre-compound, so that the product overall performance has been strengthened.
Compound glass fiber needle felt filter cloth (bag) is a glass fiber as the main material, according to the use of different mining conditions, using different techniques, mixing different chemical fiber through the needle made of high-performance filter material. Improve the wear resistance of glass fiber mat and carpet layer and peel strength between the base fabric, thus increasing the bag filter dust bag when the filtration velocity and the life.
1. P84+ glass fiber compound glass fiber scrim needled felt (filter bags)
P84+glass fiber compound needle felts are filter materials with the features of high temperature, high filtration speed and longer life.
2. Aramid fiber + glass fiber compound glass fiber needled felt (filter bags)
Aramid fibers have excellent heat resistance, flame resistance, high temperature dimensional stability. Particularly conspicuous is its excellent mechanical properties, strength and polyester similar to, wear resistance, good resistance to bending and has excellent characteristics of textile processing, can acupuncture into spun lace non-woven fabric. Aramid fiber 1313 at different temperatures, strong retention rates at different times, including in the dry heat temperature of 250 ° C for 1000 hours under the conditions of its strength retention up to 60%. Aramid fiber 1313 as a functional fiber in high temperature dust filtration industry has an irreplaceable status, but because of the characteristics of molecular structure determines it has some defects. Such as poor resistance to strong acid, high temperature hydrolysis is poor, not in the coal-fired boilers, waste incineration and other industry applications.
3. PPS + glass fiber composite needle felt applied to carbon black, calcium carbide industry, acid treatment used in ceramic industry. Acid-resistant glass fiber needle felt used in ceramic industry.
