Nowadays, in the process of producing woven bag, the pulling force of woven bag drawing is one of the important links of controlling the strength of woven bag and controlling the ratio of raw materials. So what is the ratio of raw materials for plastic woven bags? The following linyi woven bag production personnel here for our simple analysis:
I. The filling base is one of the main components in the ratio of raw materials. Its function is to improve the physical properties of drawing and reduce the cost. With the increase of the filling amount, the tensile strength of the drawing will gradually decrease.
2.The reason is that the main component of the filler masterbatch is calcium carbonate, and there is no tension. A small amount of filler masterbatch is dispersed in the gap of polyolefin polymer chain, which has little influence on the tensile strength of drawing, and the drawing stiffness is improved at this time.
3. When the additive amount exceeds 20% ~ 25%, the filler master material occupies the position of the polymer chain, hindering the elastic deformation of the polymer chain, so that the polymer chain cannot be fully stretched along the longitudinal external force, affecting the tensile orientation effect of the polymer chain and the strength of drawing. In addition, in the actual production process, the addition amount of filler masterbatch is more suitable in the range of 8% ~ 12%.
