Filter cloth material function: acid resistance, weak alkali resistance. Wear resistance, corrosion resistance and recovery are very good, and the electrical conductivity is very poor. Polyester fibers generally have a temperature resistance of 130-150 °C, which has the unique advantages of general felt filter cloths, and has very good wear resistance. It has high cost performance and becomes the most widely used felt filter material. type.

What are the requirements of the mechanical function multi-filter cloth?

The mechanical function is the general term for the tensile function, wear resistance, elongation and elasticity of the filter cloth. Different filter equipment has different requirements for the tensile function, wear resistance, elongation and elasticity of the filter cloth. In the selection of filter cloth, the variety of filter cloth should be selected according to the type of filter.

For example, the filter cloth on the filter equipment such as belt vacuum filter, endless filter cloth mobile box filter press, folded belt discharge type rotary drum vacuum filter and so on must bear a large tensile force. Therefore, choose these filter equipment. When the filter cloth is used, the tensile resistance of the filter cloth is better.

Elongation reflects the ability of the filter cloth to allow deformation. For example, the filter cloth used in the box filter press and the plate and frame filter press has a certain deformation, which requires the selected filter cloth to have good elasticity. The elasticity of the filter cloth can also be judged from the automatic recording curve of the tensile force and elongation during the stretching process of the filter cloth; the elongation at cracking is also one of the reference targets.

Wear resistance is one of the goals that reflects the life of the filter cloth. On some filter equipment, although the tension on the filter cloth is small, there is a certain friction between the filter cloth and some parts of the equipment or at the feeding port, which affects the service life of the filter cloth. For example, there is a certain amount of friction around the filter, plate frame or box filter press that removes the filter cake with a scraper, as well as at the feed port. The filter cloth used in these devices requires better wear resistance.
