Some things you should know about polyester filter cloth.

There are many materials for making filter cloth. Today we will talk about one of the polyester filter cloths. Polyester filter cloth refers to a filter material made of polyester fiber. Polyester filter cloth is divided into polyester long fiber filter cloth and polyester staple fiber filter cloth. Polyester filter cloth production material has high strength, good impact resistance, heat resistance, corrosion resistance, stagnation resistance, acid resistance and alkali resistance, good light resistance (after acrylic fiber), exposure for 1000 hours, strong 60-70% The hygroscopicity is very poor, the dyeing is difficult, the fabric is easy to wash and dry, and the shape retention is good.

Polyester filter cloth related knowledge:

1. Physical properties: temperature resistance 80-100 ° C, instantaneous temperature up to 130 ° C

2. Chemical properties: strong acid and weak base

3. Polyester filter bag classification

Cement mill: ordinary polyester needle felt, polyester easy-ash needle felt (smoothness is better than ordinary, poorer than film), waterproof and oil-proof needle felt (ie 2 anti-condensation needle felt), polyester cover Film needle felt;

Coal mill: polyester anti-static needle felt, polyester blend anti-static needle felt, polyester three anti-needle felt (waterproof and oil-proof anti-static), polyester three anti-film needle felt, polyester mixed waterproof and oil-proof needle felt , polyester mixed film needle felt;

Mixing: Conductive fiber is broken and mixed with other fibers, and the anti-static effect is good.

4. The difference between film and ordinary

Ordinary: the inner layer of the fiber is filtered, the dust enters the inside, it is easy to block, and the service life is short.

Laminating: surface filtration, dirty surface, clean interior, advantages: high filtration precision, smooth and easy to clean, waterproof, oil and corrosion resistant, long service life, additional: labor saving, time saving, power saving, disadvantages: poor gas permeability; The thicker the breathability, the better the film.

5. Post-treatment: singeing, calendering, PTFE impregnation (corrosion-resistant), heat setting (making better temperature resistance)

6. The weight of cloth: the weight per square meter, such as 500g/m2±5%, thickness 1.6-1.7mm; 550g/m2±5%, thickness 1.7-1.8mm, high filtration precision, good dust removal effect, breathable Small but not affecting production.

I hope that this article can help you a little bit of time, is able to choose the products that can really help you, I hope we are your long-term cooperation supplier.
