The plate and frame filter press has been popularized in various fields. Generally, he selects the filter cloth as the filter material. Of course, cardboard or filter paper is also used as the filter material. So in the actual operation of the plate and frame filter press, which filter cloth is good?
During the filtration of unshaped filter cloth, solid particles (fine particles) are very easy to be intercepted and block the filtering safety channel in the bell mouth, which cannot produce good railway bridge aperture clearance and endanger the actual filtering effect. Filter cake and filter cloth are bonded Harm the falling of filter cake and the water cleaning and reconstruction of filter cloth. The filter cloth after high temperature shaping has smooth surface, stable diameter structure and is not easy to deform; The bell mouth is ladder shaped, and solid particles are not easy to be blocked; It can produce very good railway bridge filter layer; The filtering precision is higher, the filter cake is easy to fall down, the filter cloth is easy to clean and rebuild, and the tightness between filter plates of the filter press is improved, the porous water leakage between filter plates of the filter press is reduced, and the actual operation of the full-automatic diaphragm filter press is more integrated. The surface high temperature shaping technology has good practical effect. Only the monofilament filter cloth can maintain a stable structure without deformation, but the impact resistance and compressive strength of the monofilament filter cloth are not as high as those of the multifilament filter cloth, and it is easy to be damaged.
At present, there are many kinds of filter cloth on the sales market, and there are many chemical fibers according to the material; According to the structure, textile and chemical fiber felt, cardboard and filter paper are dominant.
Therefore, the filter cloth manufacturer has produced a single and multiple fiber filter cloth to get rid of the shortcomings of single fiber filter cloth. The monofilament filter cloth is used as the cut-off layer, and the multifilament filter cloth is used as the supporting point layer. The filter cloth manufactured by this kind of technical production is very integrated with the application regulations of the diaphragm filter press on the filter cloth.
