Performance of Polyester Filter Cloth
(1) Resist strong acid and weak alkali.
(2) It’s stable to thick abioacid in low temperature,not dissolved in organic acid, but can be dissolved in thick vitriol and heated cresol.
(3) It’s easily hydrolyzed in strong alkali.
Applications of Polyester Filter Cloth
Dust collector or liquid-solid separation. Mainly used in food and beverage industry, pharmaceutical industry, non-ferrous metallurgy, chemical plant, building section,mining industry,etc., for the equipment of filter presses, centrifuge filters, vacuum filters, belt filter presses, etc.
