What details need to be paid attention to when purchasing ton bags?
1. Exterior scratches.
Because the packaging is too large, the ton bag is a packaging container often used in industry. It is made of chemical fiber materials. It has high strength, good moisture-proof, dust-proof, strong and other characteristics. It is commonly used. It is used in the packaging of various bulk materials in industrial production. In normal use, scratches will affect the fibrous tissue on the surface of the ton bag. This is a normal phenomenon and has almost no impact. However, when these effects continue to work on the ton bag for a period of time, they will affect the strength of the ton bag. Therefore, many surface scratches, especially partial scratches, are very dangerous. Different from ordinary wear, some wear is caused by sharp edges in the tension effect, which will seriously affect the strength of the ton bag. Ton bags can be divided into three types according to their shapes: round, square, and U-shaped.
2. Damage.
When designing a ton bag, the capacity, carrying capacity, and the number of items it can carry must be considered. At the same time, the interval, frequency, and method of transportation of the ton bag, ton bag, and container bag must also be considered when designing. Taking this problem into consideration, my country also stipulates the strength of ton bags and strictly requires that ton bags have a bottom-sling structure, and their safety factor must not be less than a ratio of 1:6. Including horizontal or straight cuts, cuts or scrapes at fabric edges, seams or cuts on lifting lugs.
3. Chemical corrosion.
The result of chemical corrosion is the weakening and softening of parts of the material. This shortcoming usually manifests itself as a thin surface on the outside of the ton bag that can be peeled off or rubbed off. In addition to being widely used in industry, it is also widely used in agriculture. For example, using ton bags to transport grain not only has low operating costs but is also easy to use and overcomes various shortcomings in the use of special bulk grain trucks. Considering the characteristics, attributes, and economy of ton bags, ton bags are the most important role in grain transportation. It is a good way to replace the packaging mode. In addition, after unloading the grain in the sales area, the ton bag can also be bundled back and used again, and the cost is very low.
4. Wear and damage due to high temperature.
This defect usually manifests itself as a fiber appearance phenomenon. Under severe conditions, fiber melting can occur.
