In the production process of woven bags, the pull-off force of woven bag drawing is one of the important aspects of woven bag strength control. Control the ratio of raw materials, now let's take a look at the plastic woven bag raw material ratio is what? The following by the plastic woven bag manufacturers for you to popularize it.
First, filler masterbatch is one of the main ingredients of the raw material ratio, the role is to improve the physical properties of wire drawing and reduce costs. With the increase of filler masterbatch filler, the tensile strength of wire drawing will gradually decrease.
Second, because the main component of the filler masterbatch is calcium carbonate, no tension, a small amount of filler masterbatch added, dispersed in the polyolefin polymer chain in the interstices, the tensile strength of the wire drawing little impact, at this time, the wire drawing stiffness has been improved.
Third, when adding more than 20% ~ 25%, filler masterbatch due to excess occupy the position of the polymer chain to hinder the elastic deformation of the polymer, so that the polymer chain can not be fully stretched along the longitudinal external force, affecting the effect of the polymer chain of the tensile orientation of the strength of the wire drawing.
Supplementary materials:.
In the actual production process, the amount of filler masterbatch added in the range of 8% to 12% is more suitable.
