Properties of various filter cloth for filter press materials
There are many types of filter cloth materials for filter presses, including polyester filter cloth, polypropylene filter cloth, nylon filter cloth, vinylon filter cloth, etc. Generally, the selection is mainly based on the characteristics of the slurry:
1. If the slurry temperature is usually relatively high when the filter press is filtering, it is recommended to use polyester filter cloth, because polyester filter cloth has very good high temperature resistance and can help filter slurry with a temperature below 150°C.
2. If the slurry has high requirements on the stretchability of the filter cloth when the filter press is working, then the company can use nylon filter cloth.
3. If the slurry is highly alkaline, you can choose vinylon filter cloth with very good alkali resistance. If the slurry is very acidic, you cannot use this filter cloth.
4. If the solid particles in the filtrate are relatively small, it is recommended to use polypropylene filter cloth.

3.Grab the exposed cloth from step 1 with vise grip pliers or equivalent, and pull the remaining cloth out of the groove.
4.Repeat step 3 to the other side of the plate.
5.Fold the one side of the filter cloth in such a way that it can pass through the hole in the center of the filter plate, and push the cloth through the plate and discard appropriately.
6.Inspect and remove any accumulated solids from the groove on both sides of the filter plate.
7.Fold one side of the new cloth in such a way that it can pass through the hole in the center of the filter plate, and pass the cloth through the hole in the center of the filter cloth.
8.Aliening the new cloth into position by lining up the corners of the cloth to the corners of the plate.
9. Using the cloth installation device, extra pound the sewn-in bead or caulk of the filter cloth, into the groove of the filter press plate. Make sure that the caulk has actually been completely seated to the bottom of the groove. Development around the groove by battering in regarding 2″ to 3″ at once.
