Liquid filter bag

Liquid filter bag


The filtrate surface of the liquid filter bag is treated with special singeing, which not only effectively prevents the fibers from detaching from the contaminated filtrate, but also avoids the traditional roller pressing treatment that causes excessive clogging of the filter holes and shortens the life of the filter bag. All raw materials are natural white, without any special bleaching and dyeing treatment, fully complying with environmental protection standards. Furthermore, due to 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 surface and the deep layer of the liquid filter bag through the deep filtration mechanism, which has a high trapping efficiency for solid or colloidal particles. The uniform thickness of the needle felt, stable opening rate and sufficient strength make the filter bag stable in efficiency and longer in use. The tightest sewing with five threads and double needles ensures that each liquid filter bag can achieve the best filtering protection. It has a wide range of applications and is suitable for liquid filtration in various industries.


①It is produced by a high-speed industrial sewing machine without silicone oil cooling, which will not cause silicone oil pollution.

②There is no high protrusion at the seam of the bag mouth after the improvement, and the side leakage is not caused by the needle hole, which leads to the side leakage.

③The labels on the filter bag that indicate the product specifications and models are all in a way that is easy to remove to prevent the label and ink from contaminating the filtrate when the filter bag is in use.

④The filter accuracy ranges from 0.5 microns to 300 microns, and the materials are divided into polyester and polypropylene filter bags.

⑤ Argon arc welding technology for stainless steel and galvanized steel ring. 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 can be installed in the equipment to improve the degree of sealing and reduce the probability of side leakage.
