PPS acid alkali resistant high temperature dust collector cloth bag

  Performance of PPS high temperature dust removal cloth bag 1
Good hydrolysis resistance, even if it is used continuously for 500h at 160 ℃, 79% relative humidity

2
After singeing and calendering, the effect of easy ash removal can be achieved

3
Heat resistance: it has a high melting point of 285 ℃, so it has long-term heat resistance, can be used continuously at 190 ℃, and has good steam heat resistance; It can maintain 90% strength even in high-pressure steam at 160 ℃

4
Chemical resistance: excellent chemical resistance is comparable to that of fluorine-containing fiber
At 200 ℃ or less, it can maintain stable chemical resistance to most acids (except some oxidants such as concentrated nitric acid) alkalis and solvents

5
Mechanical properties: it is basically the same as polyester in strength, elongation and elasticity

6
Flame retardancy: it shows , Flammability and spontaneous combustion (LOI oxygen index 34-35)

7
Radiation resistance: to & lambda; The radiation resistance of X-ray and neutral sub wire is greatly improved than that of traditional nylon and polyester

8
Electrical characteristics: under the conditions of high temperature, high humidity and high frequency, it continuously shows stable electrical characteristics
PPS fiber has integrity retention of strength and internal chemical resistance
It can maintain good filtration performance in harsh environment and achieve ideal service life
In pulse ash cleaning dust collectors for filtering natural coal boilers, waste incinerators and dust collection treatment of fly ash in power plants, it can be said that bag dust collectors with temperature and corrosivity can choose different temperature requirements, and appropriate PPS high-temperature filter bag felt can be selected as filter bag

Advantages of PPS high temperature dust removal bag:
1
Good temperature resistance, melting point 285 ℃, continuous service temperature 190 ℃, instantaneous service temperature 230 ℃

2
Excellent polyphenylene sulfide fiber is superior to Nomex conex and kermel fiber in acid resistance, inorganic acid, acid and oxidant

3
The polar oxygen index (LDI) of flame retardant polyphenylene sulfide fiber is 34-35
The fiber is a non combustible material
PPS fiber needle punched felt not only has properties, but also has , Performance
