High Temperature Coal Industry Nomex Filter Bag With PTFE Membrane
High Temperature coal Industry PTFE Membrane Nomex Filter Bag
Nomex Filter Bag Introduction:
What are the characteristics of aramid filter bags?
Aramid filter bags have excellent heat resistance, flame retardancy, and high temperature dimensional stability. Particularly eye-catching is the excellent mechanical properties of aramid filter bags, similar in strength to polyester, abrasion resistance, good bending resistance and excellent textile processing characteristics, and can be needle punched into spun non-woven fabrics. The dust-proof bag made of aramid fiber 1313 has a strong retention rate at different temperatures and at different times, including the strength retention rate as high as 60% under the condition of a dry heat temperature of 250°C for 1000 hours. Aramid fiber 1313 has an irreplaceable position as a functional fiber in the high-temperature dust removal industry, but it has certain defects due to the characteristics of its molecular structure. Such as poor resistance to strong acid, poor hydrolysis at high temperature.
Nomex Filter Bag Advantage:
strong points of high-temperature resistance, can be up to 220 degrees, good abrasion resistance, anti-adhesion.
Nomex Filter Bag Disdvantage:
easily hydrolyzed, easily rotted by acid vapors. It is therefore only suitable for certain applications.

Nomex Filter Bag Applicant:
boiler,hot asphalt concrete,the cement industry,steel factory and many other industries with dust ambient temperature
from below 200℃
Production Process:
There are 19 working produres. Every product from Sinft had undergone detailed perfection.
Scientific surface treatment like heat setting, dipping, singeing, calendering and coating can signigicantly prevent the
fabric from shrinking,remove surface batting, imrove filtration effectiveness and increase heat resistant.
Package:
The dust filter bags are packed in PP woven bags or according to your requirements.
