Knowledge sharing (production methods of PE plastic bags):
A. Slurry method. Polymerization in a diluent (such as hexane) was
the earliest industrialized method and the method with the largest
production volume so far.
B. Liquid phase bulk method. Polymerize in liquid propylene at 70°C
and 3MPa.
C. Gas phase method. Polymerizes propylene in gaseous state. The
latter two methods do not use diluent, have a short process and low
energy consumption. The liquid phase bulk method has now shown the
advantage of catching up from behind. Molding characteristics of PE
plastic bags:
A. Crystalline material has low hygroscopicity, is prone to melt
rupture, and is prone to decomposition in long-term contact with
hot metal.
B. The fluidity is good, but the shrinkage range and value are
large, and shrinkage cavities, dents, and deformation are prone to
occur.
C. The cooling speed is fast, the pouring system and cooling system
should dissipate heat slowly, and pay attention to controlling the
molding temperature. It is easy to orientate when the material
temperature is low and high pressure. When the mold temperature is
lower than 50 degrees, the plastic parts are not smooth and are
prone to poor welding and flow marks. Above 90 degrees, warping
deformation may
easily occur
D. The plastic wall thickness must be uniform to avoid lack of glue
and sharp corners to prevent stress concentration.
