The proportion of each big bag is different when it is produced, because the production of big bags cannot be composed of one kind of raw material, so in order to meet the needs of related products, in terms of the reasonable collocation of various raw materials It must be reasonable and scientific.
To ensure the strength of the base fabric, the tensile strength of the flat yarn must be increased for the ton bag. Its quality is very critical, ranging from a few hundred kilograms to a few tons. The tensile requirements are far beyond ordinary Therefore, we must be strict in the selection of materials, especially when selecting raw materials for tension, we must do a good job in the corresponding index test.
In terms of the selection of production equipment, although my country has made some progress in the production technology and depth of equipment, if we want to catch up with the world's advanced level, it is better to import some mainstream equipment, which is the hardware requirement for the production of high-quality products.
Industry experts engaged in the research and development and production of valve bags say that in the production of large bags, the selection of sling materials is very important. The suspenders must meet the weaving density requirements. When making slings for jumbo bags, two rings or four rings can be used to increase the tensile.
