Asphalt Plant Air Filter Bag Advanced PTFE Impregnation Lightweight
Anti Abrasion
Our company adopts the international advanced standard, and has
produced Aramid high-temperature needled filter felt with advanced
equipment.
According to different requirements of working conditions, our
company do various functional processing on Aramid high-temperature
needled filter felt, such as water and oil repellent, PTFE
impregnation, coating , laminating and so on.
Feature :
1. Aramid has excellent heat resistance, flame resistance, high
temperature dimensional stability.
2. 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.
3. Aramid fiber 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%.
4. Aramid fiber 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.
Application:
1. Remove the impurities of oil in the petrochemical industry
2. Filtration of sugar, spices, juices, tea in
the food industry
3. Solution and solvent filtration in the production of polyester
and acrylic fiber
in the textile industry
4. Clarification of valuable ingredients,
and filtration of gelatin, cellulose and medicinal water in the
pharmaceutical industry.
