What about the key points for selecting flour mesh?...

Really understand the polyester filter cloth?
 
What is the relationship between the polyester filter cloth and its characteristics and performance classification are as follows:
 
1. Heat resistance: 120 ° C, elongation at break (%): 20-50, breaking strength (g/d): 438,
 
2. Melting point (°C): 238·240, melting point (°C): 255-260. Proportion: 1.38.
 
3, polyester filter cloth filter cloth classification: polyester long fiber filter cloth, polyester staple fiber filter cloth.
 
4, polyester filter cloth filtration performance: polyester long fiber filter cloth surface is smooth, wear resistance, high strength, after the fight, the strength is higher,
 
The wear resistance is better, so that the fabric has good air permeability, quick water leakage and convenient cleaning.
 
The raw material structure of polyester short fiber filter cloth is short and hairy, the fabric weaved is dense, and the particle retention is good.
 
1. Polyester filter cloth According to the filtration pressure, filter cloth with different tensile strength and elongation is selected.
 
2. The filter cloth of different materials should be selected according to the pH value of the sludge. Generally, in order to extend the service life of the filter cloth, the polypropylene series filter should be used in the environment of pH 4~8. The nylon series filter cloth should be at pH value 5~ Used in the environment of 8.5.
 
3. The filter cloth that can effectively intercept the sludge particles during filtration should be selected according to the nature of the sludge and the particle size, mainly for the pore size of the filter cloth and its water permeability (breathability).
