The aging of tons of bags is mainly due to the formation of ultraviolet light in the sun, ultraviolet light caused the degradation of polypropylene, so that tons of bags show tension reduction, powder, fading and other appearances of the value of tons of bags is not high, a general ton of bags is a few dollars, but the materials carried are thousands or even thousands of times the value, so the safe use of tons of bags is a very important issue.
In order to transport the safety of materials, the general aging resistance of tons of bags is required, reaching half a year or more, of course, depending on the specific needs of customers in fully understanding the mechanism of aging of tons of bags, the elements of aging and the specifications of aging inspection of tons of bags base cloth can be fully satisfied with the customer's demand for anti-aging tons of bags
Here are some suggestions for further preventing the aging of tons of bags:
First: To fully understand the customer's needs for anti-aging of the ton package, such as the use of address, the use of time cycle, etc., some customers will provide artificial accelerated aging test time and final retention strength, and even some customers will specify the increase of UV additives, according to the needs of customers, develop the technical plan of the product II: planning the production formula.
Due to the aging of recycled materials, molecular chain cracking, mechanical properties have been greatly reduced, the use of tons of bag base cloth life is sharply shortened, raw materials are necessary to choose new materials to deal with the aging of tons of bags, it is necessary to increase anti-aging additives in accordance with a certain proportion if the use of UV additives will make the dispersion of materials difficult to deal with, the formation of technical processing is difficult, And anti-aging masterbatch can be useful to deal with this question.
For the color of the product, according to customer requirements, select different fast grades of color masterbatch 3: For the anti-aging masterbatch that improves the aging resistance of tons of packages, customers should be stable to investigate, although the increase is small, but the effect is very crucial, it is necessary to put forward strict requirements for the anti-aging masterbatch supplier to fully ensure the quality of the product 4: A ton of sound bag base cloth contains the base cloth, sling, cloth and sewing thread, which must meet the needs of anti-aging, if a problem, severe results will occur, many users have been subjected to similar experience.
