How to improve the flexibility of steel strapping

Toughness is an important performance for judging the quality of the packaging steel belt. So how should the flexibility of the packaging steel belt be improved?
　　 The production filler of steel strapping is a key point. Calcium carbonate has been used as an inorganic filler in plastic supplements to reduce the cost of products for many years, and good results have been obtained. Therefore, it is widely used in many industries. The more calcium carbonate is added to the plastic, the lower the cost will be. Of course, calcium carbonate cannot be added to the website construction company infinitely. Considering the toughness of plastic products, the amount of calcium carbonate added is usually controlled within 50wt%.
　　 Through a large number of experiments, it has been found that after adding a larger amount of ultrafine calcium carbonate particles to the plastic, not only the rigidity of the plastic is not damaged, but the toughness is also greatly improved, and the maximum can be increased by 2 to 3 times. However, the cost of this kind of ultrafine calcium carbonate particles is relatively high, but using them as a supplement to be put into production can change the cost of certain mechanical properties in the past to supplement plastics. The mechanical properties of modified plastics vary with the amount of filler supplements. The state of growing and falling.
