filter fan of pressurized filter press

The selection of filter cloth of filter press is very important to the filtering effect. In the process of using filter press, filter cloth plays a key role. The quality of its performance and the correctness of its selection directly affect the filtering effect. At present, the commonly used filter cloth is the synthetic fiber woven filter cloth. According to the different materials, it can be divided into polyester, vinylon, polypropylene, nylon and so on. In order to achieve the ideal interception effect and filtration speed, the selection of filter cloth also needs to be based on the particle size, density, chemical composition and filtration process conditions. Due to the different materials and methods of weaving, the strength, elongation, permeability and thickness of the filter cloth are different, thus affecting the filtering effect. In addition, the filter medium also includes cotton spinning cloth, non-woven cloth, screen, filter paper and microporous membrane, which are determined according to the actual filtering requirements.

Performance characteristics of common filter cloth:

(1) Performance polyester nylon polypropylene vinylon

(2) Strong acid resistance, good acid resistance or not

(3) Alkali resistance, weak alkali resistance, good strong alkali resistance

(4) Very poor electrical conductivity, good general

(5) Elongation at break 30% - 40% 18% - 45% large and polyester 12% - 25%

(6) Good recovery at 10% elongation, recovery over 90%, slightly better than polyester

(7) Wear resistance is very good, very good and good

(8) Heat resistance 170 ℃ 130 ℃ slightly shrink 90 ℃ slightly shrink 100 ℃ slightly shrink

(9) Softening point 230-240 ℃, 180 ℃, 140-150 ℃, 200 ℃

(10) Melting point 255-265 ℃ 210-215 ℃ 165-170 ℃ 220 ℃
