Waste Water Treatment Filter Cloth

The waste water treatment filter cloth material of the filter press can withstand any dust with high temperature and contains a large amount of corrosive substances such as sulfur dioxide, nitrogen oxides, carbon dioxide, acid, etc. When using filter press equipment, it is necessary to use the filter cloth of the filter press to achieve good filtration effect. Characteristics of customized Waste water treatment filter cloth for filter press;

1. Acid and alkaline resistant, with tensile strength.

2. After shaping treatment, it is smooth and flat, with good breathability and water permeability.

3. The characteristics of toughness and durability, easy peeling and easy regeneration of filter cakes.

4. The interface is sewn with acid and alkali resistant strong thread, which is durable.

Waste water treatment filter cloth application: Widely used in fields such as chemical engineering, metallurgy, petrochemicals, pharmaceuticals, food, minerals, ceramics, etc., suitable for various types of filter presses such as frame, box, and diaphragm.If necessary, we can provide free samples.

Product Feature And Application

1.polyester Waste water treatment filter cloth is divided into polyester long fiber filter cloth and polyester short fiber filter cloth. Material performance of polyester short fiber filter cloth: acid and weak alkali resistance. Good wear resistance, corrosion resistance, recovery, but poor conductivity.

Polyester fibers generally have a temperature resistance of 130-150 degrees Celsius. In addition to the advantages of ordinary felt filter fabrics, this product also has good cost-effectiveness and wear resistance, making it a widely used variety in felt filter materials.

Polyester filter cloth uses: pharmaceutical, sugar making, food, chemical, metallurgical, industrial filter press, centrifuge, etc.

Parameters of polyester filter cloth

Heat resistance: 120℃,

Breaking elongation (%): 20-50,

Breaking strength (g/d): 438,

Melting point (℃): 238-240,

Melting point (℃): 255-260.

Specific gravity: 1.38.

Filtration performance: The raw material structure of polyester short fiber Waste water treatment filter cloth is short and woolly, and the woven fabric is dense, with good particle retention, but poor peeling and breathability. Strength, wear resistance, and water leakage are not as good as polyester long fiber filters.

2.Nylon Waste water treatment filter cloth have high strength, ranging from 4-5.3cN/dtex. The elongation is between 18% and 45%. At 10% elongation, the elastic recovery rate is above 90%. Nylon has a relatively strong strength among fibers. According to measurements, the wear resistance of nylon fibers is 10 times that of cotton fibers and 50 times that of viscose. Due to its superior wear resistance compared to various fibers, it is an ideal material for manufacturing automotive tires when pressed together with rubber. Nylon fibers are resistant to strong alkalis and weak acids. After being treated with NaoH (10%) at 95℃ for 16 hours, the strength loss can be negligible, but nylon is not light resistant and prone to discoloration and brittleness. Therefore, nylon fabrics should not be exposed to sunlight for a long time.

Usage: Rubber, ceramics, pharmaceuticals, metallurgy, etc.

3.Polypropylene Waste water treatment filter cloth classification: polypropylene short fiber filter cloth; Polypropylene long fiber filter cloth.

Filtration performance: polypropylene short fiber, short fiber, spun yarn with wool; Polypropylene fiber is a long fiber that forms a smooth yarn. Therefore, industrial fabrics made of polypropylene short fiber are more effective in terms of surface fuzzing, powder filtration, and pressure filtration compared to long fibers. Industrial fabrics made of polypropylene long fibers have a smooth surface and good breathability.

4.The chemical name of vinylon Waste water treatment filter cloth is polyvinyl alcohol, and its strength is lower than polyester, with a strength of only 3.52-5.72Cndtex. The elongation at break is 12% to 25%. Poor elasticity, poor shape retention of fabric, good wear resistance, 1-2 times longer durability than pure cotton. But one advantage is that it can withstand strong alkalis and has good moisture absorption, making it easy to combine with rubber. It is a good material used in the rubber industry. Its disadvantage is that it has low temperature resistance, shrinkage when the temperature reaches 100℃, and is not resistant to acidity. Purpose: For manufacturers with strong alkalinity and the rubber industry.
