Ton bags are a type of plastic woven product made of polypropylene. After packaging bulk materials, they can be used to transport goods very well and are loved by many industries. However, during its use, there are many troubles caused by material aging. So how we solve the aging problem of ton bags? Is there a good way?
The aging of ton bags is mainly caused by ultraviolet rays in sunlight. Ultraviolet rays cause the degradation of polypropylene, which causes the ton bags to show reduced tension, powdering, fading, and other phenomena. Although the value of ton bags is not high, a general ton bag is only a few tens of yuan, but the materials it carries are thousands or even tens of thousands of times more valuable. Therefore, the safe use of ton bags is a very important question. To transport materials safely, the general aging resistance of ton bags is required to reach half a year or even more than a year. Of course, the specific needs of customers depend on it. Based on fully understanding the aging mechanism of ton bags, aging factors, and aging inspection standards, customers' needs for ton bag anti-aging can be fully met.
To solve the anti-aging problem of ton bags, the following points need to be achieved:
1: Fully understand the customer's demand for the anti-aging of ton bags, such as the place of use, the period of use, etc. Some customers will provide the test time of artificial accelerated aging and the final retention strength, and some customers will even specify the amount of UV additives added. According to customer needs, formulate a technical plan for the product.
2: Plan the production formula. Because the recycled material has aged, the molecular chain has cracked, the mechanical properties have been greatly reduced, and the service life has been sharply shortened, the raw materials must be new. To solve the aging problem of ton bags, it is necessary to add anti-aging additives in a certain proportion. If UV additives are used, the dispersion of the material will be difficult to handle, resulting in technical processing difficulties, and an anti-aging masterbatch can effectively solve this problem. For the color of the product, according to customer requirements, select masterbatches with different light resistance levels.
3: For anti-aging masterbatches that improve the aging resistance of ton bags, customers should carefully investigate. Although the amount of increase is small, the effect is very important. It is necessary to put forward strict requirements on the anti-aging masterbatch supplier to fully guarantee the quality of the product.
4: A good ton bag contains base cloth, slings, material cloth, and sewing thread, all of which must meet the requirements of anti-aging. If a problem occurs, serious consequences will occur. Many users have had similar experiences.
Methods to prevent ton bag aging:
1. Waterproof and moisture-proof problems when using ton bags. Ton bags should be dried immediately after use.
2. Acidic substances should be prevented from contacting ton bags during use. Ton bag manufacturers remind everyone that if acidic substances are transported, they need to be packaged well.
3. Ton bags cannot be placed in places exposed to sunlight because long-term exposure to sunlight will directly cause damage to ton bags. Sunlight contains ultraviolet rays, and ultraviolet rays will directly oxidize polypropylene materials.
The better the ton bag is protected, the longer its service life will be so that it can do more work and reduce costs accordingly. Find the right method to face the aging problem of ton bags, and hope to help more people.
