The aging of the ton bag is mainly caused by the ultraviolet rays in the sunlight, which causes the degradation of polypropylene, which makes the ton bag appear low in tension, chalking, and fading. Although the price of a ton bag is not high, an ordinary ton bag costs a few dollars, but the material carried is thousands or even tens of times the cost. Therefore, the safe application of the ton bag is an extremely important problem. In order to convey the safety of the material, the normal aging life of the tons of bags is required, reaching half a year or even more than a year, although the details depend on the needs of customers. After fully understanding the aging mechanism of ton bags, the elements of aging and the standards for aging introspection can fully meet the needs of customers for anti-aging of ton bags. To improve the anti-aging effect of the ton bag as a whole, Corfu convened its own experience and feedback from customers, and recommended the following:
The first point: To fully understand the customer's need for anti-aging of tons of bags, such as application location, application period, etc., some customers will provide artificial accelerated aging test time and ultimate storage intensity, and even some customers marked UV The growth amount of additives, according to the needs of customers, set the technical plan of the product.
Second point: stop planning the production formula. Because the recycled materials are now aging, the molecular chain is cracked, the mechanical properties are now greatly reduced, and the application life is prolonged sharply. It is necessary to use new materials for the raw materials. 吨袋 的老化疑难，就有需要按照必定比例增长防老化助剂。 To deal with the aging problem of tons of bags , it is necessary to increase the anti-aging aid in a certain proportion. If the application of UV additives makes the dispersibility of the material difficult to handle, the processing is difficult, and the anti-aging masterbatch can effectively handle this problem. For finished colors, we need to choose different color masterbatches based on customer requirements. Plastic woven cloth
Third point: To deal with anti-aging masterbatches that increase the aging resistance of ton bags, customers must pay attention to visits, although the increase is small, but the consequences are critical. It is necessary to make strict requests to the anti-aging masterbatch suppliers to adequately manage the products Quality.
The fourth point: a good ton bag includes base cloth, sling, material cloth and sewing thread, all of which must meet the needs of anti-aging. Resume.
