The aging of the ton bag is mainly due to the formation of ultraviolet rays in sunlight, and the ultraviolet rays cause the degradation of polypropylene, which leads to the phenomenon of decreased tensile force, chalking, and fading of the ton bag. How to do a good job in the anti-aging effect of ton bags, the propositions are as follows:
To fully understand the customer's anti-aging requirements for ton bags, such as use address, service cycle, etc., some customers will provide artificial accelerated aging test time and retention force, some customers will increase the amount of standard-definition UV additives, and formulate products according to customer needs. Technical solutions.
Point 2: Develop a shipping plan. Because the recycled material has been aged, the molecular chain is broken, the mechanical properties are greatly reduced, and the service life is shortened sharply. In order to solve the problem of aging of ton bags, anti-aging additives must be added in a certain proportion. It is assumed that the use of UV additives will make the dispersion of the material difficult to handle, resulting in a difficult process, and the anti-aging masterbatch can help solve this problem. The color of the product should be selected according to customer requirements, and color masterbatches with different lightfastness should be selected.
3.1: For the anti-aging masterbatch that improves the anti-aging effect of ton bag and ton bag manufacturers, customers should investigate carefully. Although the added amount is small, the effect is very harmful. Strict requirements must be imposed on the anti-aging masterbatch supplier to fully guarantee product quality.
One ton of 13800 contains base cloth, suspenders, cloth mouth cloth, and sewing thread. These four basic functions meet the requirements of anti-aging. Once problems occur, the effect is very poor, and many users have similar experiences.
