Film bag

I plant the production of coated needle felt filter pore size is small enough to put teflon 5um or less cover the surface of the filter needle felt a composite filter. The film filter characteristics: PTFE film surface is smooth and chemicals, to Ordinary laminated to the surface of the filter material, acts as a one-off layers of dust, the dust trapped in the entire surface of the film to achieve surface filtration ; because of the film surface smooth, with excellent chemical stability, aging, and water-repellent, so trapped in the surface dust is easily peeled off, while increasing the life of the filter. Compared with the general media, its advantages are: 1. Film aperture between 0.23um, filtration efficiency can reach 99.99%, almost zero emissions. After cleaning the porosity does not change, the collection efficiency has been high. 2. At the beginning of the use of membrane filter media, the pressure loss is higher than the general media, but after put into operation, the pressure loss increases with the use of the time change is not large, and the pressure loss in the general media will be extended with the use of time and growing. 3. Ordinary dust filter in use, easy access to the interior, and piled up until blocked pores, resulting in unusable. The use of PTFE membrane filter, filter dust can be easily removed from the film surface, good cleaning effect, long cycle, low pressure cleaning using the strength, thereby increasing the life of the filter, and significantly reducing maintenance workload precipitator maintenance, reduced operating costs of products, and woven filter and a filter needle felt laminated, made of PTFE membrane filter media, it is widely used in flue gas purification dust, dust Governance and special recycling and other fields. 4. The membrane filter media also has good chemical stability, heat resistance and chemical resistance properties.
