PPS filter bag , PPS filter felt is a filter material manufactured and processed by our company according to the production process of other high temperature resistant filter felt with polyphenylene sulfide (PPS) fiber produced in the United States, Japan and other countries
It is one of the main varieties of high temperature resistant filter materials
PPS needle punched filter material has excellent neutral performance in the following applications
PPS is also known as polyphenylene sulfide fiber
The fiber is a new type of high temperature resistant fiber developed by Phillip company and introduced to the market in 1983
At present, China's high temperature resistant needle punched filter felt market mainly produces needle punched filter felt with organic fiber Nomex conex, kermel and inorganic fiber glass fiber as raw materials
The physical properties of organic fiber are obviously better than inorganic fiber
Polyphenylene sulfide fiber is another kind of high-function fiber among high-temperature resistant organic fibers in recent years
It not only can withstand high temperature, but also has incomparable excellent corrosion resistance of other high-temperature resistant fibers The needle punched felt made of polyphenylene sulfide fiber has the following outstanding advantages: 1
Good temperature resistance, melting point 285 ℃, continuous service temperature 190 ℃, instantaneous service temperature 230 ℃
2
Excellent corrosion resistance polyphenylene sulfide fiber is superior to Nomex conex and kermel fiber in resistance to organic acid, inorganic acid, acid and oxidant
3
Excellent flame retardant polyphenylene sulfide fiber has a polar oxygen index (LDI) of 34-35
This fiber is a non combustible material
PPS fiber needle punched felt not only has high temperature resistance, but also has unique corrosion resistance It is widely used in smelting, chemical industry, building materials, thermal power, waste incinerator, coal-fired boiler and other industries under high temperature and harsh working conditions
It is a high-quality, high-efficiency and high-temperature resistant filter material
Our company selects polyphenylene sulfide fibers produced in the United States and Japan and specializes in producing polyphenylene sulfide (PPS) needle felt according to other high-temperature needle felt production processes
The product quality has reached the level of similar products in foreign developed countries

PTFE dust removal cloth bag the PTFE needle felt produced by us is made of 100% PTFE fiber through needling or water pricking on the PTFE base cloth, Without adding any other raw materials and additives, the original characteristics of polytetrafluoroethylene (PTFE) will not be changed
Therefore, PTFE needle punched felt has high temperature resistance, strong acid and alkali resistance and other corrosive gases, as well as good abrasion resistance, difficult combustion and good insulation and heat insulation
PTFE needle felt membrane filter bag is widely used in urban waste incineration dust collection, chemical dust removal and other harsh working conditions
It can resist acid and alkali, any corrosive gas and high filtration precision
It is the most ideal dust removal bag for waste incineration
The specific features are as follows:
1
Physical properties
The surface is smooth, hardly absorbing water, and the transmittance to water vapor is also low
2
Low friction coefficient
The friction coefficient of PTFE is the smallest among solid materials so far
3
Extremely wide heat resistance
Operating temperature range: - 200-260 ℃
PTFE has the highest thermal stability among thermoplastics
It does not lose its self-lubricating property at low temperature, has high strength and still has flexibility at - 80 ℃
4
Chemical resistance
PTFE fiber can withstand many highly corrosive media and is hardly affected by any chemicals (except alkali metals, alkaline earth metals and their compounds above 350 ℃ under high pressure)
It is not affected by moisture, mold, bacteria, ultraviolet light, etc
5
Good conductivity
PTFE is the most poor corona resistant fiber
