PTFE Water Filter Bag Product Introduction:

The filtrate surface of the liquid filter bag is treated with special singeing, which can effectively prevent the fiber from escaping from the contaminated filtrate, and can avoid the excessive clogging of the filter hole caused by the traditional rolling treatment and shorten the life of the filter bag. All raw materials are white, without any special bleaching treatment, fully comply with environmental protection standards, and because of the three-dimensional filter layer of the needle felt, when the liquid flows through the filter bag, the particles will stay on the inner wall of the liquid filter bag due to the deep filtration mechanism. Surface and depth, high capture efficiency for solid or colloidal particles. The thickness of the needle felt is uniform, the stable opening ratio and sufficient strength make the filter bag stable and the application time is longer. The tightest sewing of the five-wire double needle ensures that every liquid filter bag achieves the best filtration results.

PTFE Water Filter Bag Product Characteristics:

1. The production of high-speed industrial sewing machine without silicone oil cooling will not cause the problem of silicone oil pollution.

2. There is no high protrusion after the improvement of the seam at the mouth of the bag, and the side leakage caused by the side leakage has no pinhole and causes side leakage.

3, the label on the filter bag marked with the product specifications and models are all selected to facilitate the removal of the filter bag to prevent contamination of the filtrate by the label and ink in use.

4, the filtration accuracy ranges from 0.5 microns to 750 microns, the material is divided into polyester, polypropylene, nylon and other filter bags.

5, stainless steel and galvanized steel ring argon arc welding technology. The diameter error is only less than 0.5mm, and the horizontal error is less than 0.2mm. The filter bag made of this steel ring is installed in the equipment to improve the sealing degree and reduce the probability of side leakage.

6. The plastic ring has a diameter of 105, 120, 150.180, 200, 220, etc.

PTFE Water Filter Bag Product Application:

1.It is widely used in various sewage and corrosive liquids, and some filter tanks that need to be fixed by plastic bayonet.

Electronics industry: removal of impurities in copper foil electrolysis stabilization tank, removal of zinc deposits in zinc hydroxide solution, filtration of coolant

2.Petrochemicals: filtration of aviation kerosene, filtration of lubricating oil, recovery of oils, filtration of liquids and gases in PVC production, filtration of petroleum and fuel oil additives, desulfurization of oil and natural gas and filtration of amine liquids

3.Automobile: degreasing filter for electrophoretic paint, pre-filtration for ultrafiltration, filtration of varnish and topcoat, pretreatment of deuterated liquid and water, degreasing of pretreatment solution, filtration of vehicle spray water

PTFE Water Filter Bag Instructions:

 1. Check whether the model size of the installed filter bag is consistent with the filter interface, and check the quality of the new filter bag for defects.

2. The filter bag must be used together with the support net and close to the inner wall of the support net. Pay attention to check that the blue inner wall of the support net has no burrs.

3. When the pressure difference between the upstream and downstream of the filter is 1-1.5Kg/cm2, please replace it with a new filter bag or clean the filter bag.

4. Filter bags are usually made of fine polypropylene, nylon or polyester filters. These materials are less hydrophilic and the surface of the fibers is not wetted by water, so use other surfaces before use. The liquid with lower tension will wet it. Before installation, you must immerse the filter bag in the filtered liquid for a few minutes. After the fiber is wet, the liquid is sucked into the filter material by capillary action, which can effectively Reduce the initial pressure loss.
