Coated polyester needle punched felt dust bag

Characteristics of laminated polyester needle punched felt dust removal bag: high air permeability, low resistance, good filtration efficiency, large dust holding capacity, and high dust stripping rate. It is the filter material for dust removal. Microfiltration: After PET, PP and other non-woven fabrics are coated, they can be made into filters and filters for industries such as chemistry, medicine, electronics, etc. They can filter out micro particles and isolate bacteria while maintaining high filtration efficiency and low flow resistance. Industrial filtration: Polyester felt and PET film can be used to make various filter bags, filter cartridges, and filters, which are widely used in the treatment and recovery of industrial flue gas and dust particles such as cement, metallurgy, food, coating, petrochemical plastics, etc.

The advantages of laminated polyester needle punched felt dust bag include:

1. The membrane pore size is between 0.2-3 μ m, and the filtration efficiency can reach above, almost achieving zero emissions. After cleaning, the porosity remains unchanged, and the dust removal efficiency remains high.

2. At the beginning of use, the pressure loss of laminated filter media is higher than that of ordinary filter media, but after being put into operation, the pressure loss does not change much with the increase of use time, while the pressure loss of ordinary filter media will increase with the extension of use time.

3. Ordinary filter media is prone to dust entering the interior during use, and it accumulates more and more until the pores are blocked, making it impossible to continue using. By using PTFE coated filter media, the filtered dust is easily removed from the membrane surface, resulting in good cleaning effect, long cycle, and low cleaning pressure intensity. This improves the service life of the filter media and reduces the operating costs of the product.
