-Features of Water&oil repellent Needle Felt:
1. Oil repellent performance. It can prevent oily dust from sticking to the bag easily and avoid the disadvantages of clogging the filter cloth.
2. Water resistance. It can exclude water-soluble dirt or condensed water droplets and prevent the filter cloth from reducing its filtering capacity.
-Performance facts:
(1) Resist strong acid and weak alkali.
(2) Stable to thick abioacid in low temperature, not dissolved in organic acid, but can be dissolved in thick vitriol and heated cresol.
(3) Easily hydrolyzed in strong alkali.
Application
Liquid-solid separation and dust collection. Mainly used in the precision chemical industry, sugar-refinery, pharmaceutical, alumina industry, etc., for equipment of frame filter press, belt filters, blend belt filter, disc filters, drum filters, centrifuge filters, etc.
