Product Description
Dust Collection Fittings--Replacement Filter Bags Supplier
Filter bag is the core of the dust filter components. The filter bag has the strict requirements on design, filter material cutting, woven technology etc. These requirements are very important for the normal operation of the bag filter and convenient maintenance, and it is great significance to enlong the service life of the filter bag.
The filter bag sewing need attention:
Filter bag sewing material should be the same as the material of filter material. In special circumstances, we will adopt to use different filter material of sewing thread, the suture properties such as strength, heat resistance and chemical resistance should be better than the filter material sewing thread.
The filter bag stitching line:
Filter bag bag body vertical stitches must be strong, straight, and shall not be less than three line. The bag top and bottom according to different requirements with single or double needle stitching. Filter bag suture needle closely related to the filter bag material, not only to ensure the stitching rigor and suture strength not leak dust, but also shall not damage the strength of the filter material itself.
The Needle density of chemical fiber filter material filter bag should within 10 cm length (25 + / - 5) needle; Glass fiber filter material filter bag needle density can not too large. The stitching width normally for 9 ~ 12 cm. The stitches and distance on the edge of the filter material: needled felt for 2 ~ 3 mm, glass fiber filter material is 5 ~ 8 mm.
Filter bag should be according to the design requirements for inspection and repair after sewing, eliminate surface crease, dirt and grease. For PTFE coated filter bag, in addition to the needle density control and strict operating procedures, it needs to use special materials for all the pin hole repairing.
Inspection of filter bag:
Filter bag manufacture should be according to the national standards, industry standards and enterprise standards, quality supervision departments according to the number of sampling test project and the proportion. According to the number of sampling ratio is 5% ~ 20%. For higher requirements on the filter bag, As a group of sampling rate should be above 15%.
