One: To fully understand the customer's needs for aging of woven bags, such as use address, life cycle, etc. Some customers will provide artificial accelerated aging test time and retention strength, and even some customers indicate the increase in UV additives According to customer needs, formulate technical plans for commodities.
2: Plan the production formula. Because the reclaimed material is now aging, the molecular chain has cracked, the mechanical properties have been greatly reduced, and the service life has been shortened sharply. It is necessary to use new materials for raw materials. To deal with the aging problems of woven bags, it is necessary to add anti-aging additives according to a certain proportion. If the use of UV additives makes the dispersibility of the material difficult to handle, the formation of technical processing is difficult, and the anti-aging masterbatch can effectively deal with this doubt. The color of the products should be selected according to customer requirements, and masterbatch with different lightfastness grades should be selected.
3: For the anti-aging masterbatch of the anti-aging effect of the woven bag, the customer should investigate steadily. Although the increase is small, the effect is very strong. It is necessary to put forward strict requirements on the anti-aging masterbatch supplier to fully guarantee the quality of the goods.
Four: A good woven bag contains the base fabric, sling, material mouth cloth and sewing thread, which must meet the needs of anti-aging. If a link fails, serious consequences will occur, and many users have experienced similar experiences.
