Dust bag sewing technique takes into account to facilitate the production on the mechanical rapping style flat bag filter uses a unified specification dust bag. If users have any special needs, our company can also provide customized. Dust bag sewing thread in two ways: using a polyester needle felt sewing room temperature using a thick nylon line; high-temperature dust bag must use fiberglass sutures sutures industrial dust bag, which is covered by organic monofilament diameter of 5.5μm fiberglass yarn plied and twisted, and then by special surface chemical treatment is made, having 80--120N tensile strength, 25--35N knot strength dust bag, the appearance of a diameter of about 0.5mm. Sewing bag is an extremely important work, production to be precise, check carefully, storage should be appropriate. It directly affects the life of the filter bag and the dust level of efficiency. Therefore, we must cooperate with the bag when sewing lining mesh well, even by force when tightening to ensure that the upper and lower bag was the steeple, the bag does not affect the lower ash through the upper bag. The bag and the bag bottom in the process, the strength of the parts of the United States vulnerable to the loss of Andean dust bag, bag use is the weak point of polyester dust bag, measures should be taken to strengthen. Use show that the bag is often damaged at these places, Central rarely happens. Horizontally mounted bag, wearing harm ends sticking out, easy to spot check should then be stuck up perfect. A dust bag of craft techniques, drying: using about 110 ℃ hot air drying, maintain dimensional stability bag, bag after drying no distortion, no retraction. 2. Fix: to abrasion, holes and other damage due to the use of bags produced to repair, to ensure a high rate of return. 3. detection: the use of instruments of the bag after cleaning the physical indicators of testing to ensure the quality of cleaning to meet the requirements. After the above treatment step, the bag can be achieved after cleaning requirements. Precisely because of the dust bag dust removal efficiency has a decisive role, so we have to protect the life of the dust bag, in order to increase the life of the filter. 4, cleaning: high frequency vibration, the larger dust particles into the inside wall of the bag as much as possible clear, will not have an impact on the fiber entangled fastness, maintain good peeling resistance bag. 5, chemical experimental treatment: Extract sample bag, a professional laboratory testing equipment bag oil composition, thus the choice of materials adapted to wash, wash bag to maximize the bag but not cause any damage. 6. Cleaning: use proper cleaning materials and strict ratio, low temperature water cleaning, water even, moderate intensity, no mechanical damage to the bag.
