Full hot melt needle felt filter bag

Time : 2023-06-27 Hits : 3

rief overview of full hot melt needle felt filter bag:

Plastic ring mouth is used along the mouth, and the main material is special liquid filter material. The filtering surface of the filtrate is specially singed, which not only effectively prevents the fiber from separating from the contaminated filtrate, but also avoids the excessive blockage of the filter hole caused by the traditional rolling treatment and shortens the service life of the liquid filter bag. All raw materials are white, without any special bleaching and dyeing treatment, and fully comply with the environmental protection standards. Moreover, due to the three-dimensional filter layer of the needle felt, when the liquid flows through the needle felt, the particles will stay on the inner wall surface and deep layer of the liquid filter bag due to the deep filtering mechanism, which has high capture efficiency for solid or colloidal particles. The needle felt in the full hot melt needle felt filter bag has uniform thickness, stable opening rate and sufficient strength, so that the efficiency of the liquid filter bag is stable and the operation time is longer. The method of connecting the bottom, side and collar of the hot-melt filter bag is welded by the hot-melt method, which avoids the pinholes caused by the sewing of the line seam filter bag and is suitable for the field with higher precision requirements; The high-precision wireless seam filter bag adopts digital co location multi-point welding equipment to ensure that each point of welding is firm and consistent. Ensure that the filter bag is not affected by other production auxiliary materials, and ensure the consistency of each filter bag material.

Advantages of full hot melt needle felt filter bag:

1. The plastic ring mouth is used along the mouth of the filter bag, and the material is the special liquid filter material of the industry standard.

2. The surface of the filter bag is specially singed, which can effectively prevent the fiber from separating from the contaminated filtrate, and because the needle felt of the full hot melt needle felt filter bag has the characteristics of a three-dimensional filter layer, when the liquid flows through the needle felt, the particles will stay on the inner wall surface and deep layer of the liquid filter bag due to the deep filtering mechanism, which has a high capture efficiency for solid or colloidal particles.

3. The uniform thickness of the needle felt, the average opening and the strength of the material make the efficiency of the liquid filter bag stable, the service time longer, and the filtering effect higher.

Full hot melt needle felt filter bag application:

Fine chemical industry

water treatment

Paint coating

Parameters of full hot melt needle felt filter bag:

Filtering precision: PP 0.4-500 μ、 PE 0.5--300 μ、 NMO 1--2000 μ

Working temperature: polypropylene 90 ℃, polyester 150 ℃

Differential pressure: 2.5bar

Replacement pressure: 0.8-1.5bar

In addition, it should be remembered that the differential pressure of bag filter directly affects the flow, and a new filter bag must be replaced when the differential pressure is 0.2 MPa. The particle content and viscosity of the medium will affect the service life of the filter bag.
