What are the materials of filter cloth for filter press?

There are many types of filter cloths for filter presses, mainly classified according to different materials and structures. The following are some common types of filter cloth for filter presses:

1. Polyester filter cloth: Polyester filter cloth is made of polyester fiber, which has strong acid and alkali resistance, excellent tensile strength and wear resistance.
   Suitable for general filtration conditions and widely used in chemical, food, pharmaceutical and other industries.

2. Nylon filter cloth: Nylon filter cloth is made of nylon fiber and has excellent heat resistance and wear resistance. It is suitable for filtration operations under high temperature and high viscosity conditions.
   Commonly used in petrochemical, fine chemical, papermaking and other industries.
3. Polypropylene filter cloth: Polypropylene filter cloth has good acid and alkali resistance and temperature resistance, and is suitable for filtration operations in acidic and alkaline media and low temperature conditions.
   Commonly used in chemical, mining, metallurgical and other industries.
4. Polyester filter cloth: Polyester filter cloth is made of polyester fiber, which has the advantages of acid and alkali resistance, temperature resistance and wear resistance, and has good filtration effect under general filtration conditions.
   Commonly used in chemical, food, environmental protection and other industries.

In addition to the above common types of filter cloth, there are also filter cloths made of special materials, such as wear-resistant polytetrafluoroethylene filter cloth, high-temperature-resistant glass fiber filter cloth, etc. The appropriate type of filter cloth can be selected according to specific filtration requirements.
When selecting filter cloth, factors such as process conditions, the nature and requirements of the filter medium, and filtration efficiency need to be considered to ensure good filtration of the filter cloth.
