Production process of thick clear plastic sheeting rolls
The thick clear plastic sheeting rolls has the advantages of moisture resistance and low moisture permeability, and is very popular among users. Knowing its production process can help us produce better quality film. In the production of thick transparent plastic film rolls, dry polyethylene particles are first added to the lower hopper, and the granules enter the screw by the weight of the particles themselves. When the granules are in contact with the helical ribs, the rotating ribs face the plastic. Produces a thrust perpendicular to the beveled surface to push the plastic particles forward.
During the process of the transition, due to the friction between the plastic and the screw, the plastic and the barrel, and the collision between the particles, it is also heated by the outside of the barrel. Thereby gradually melting. In addition, the molten plastic passes through the filter head of the machine to remove the impurities from the die die. After being inflated and cooled by the air ring, the plate is pressed by the herringbone, and the finished film is wound into a cylinder by the pulling roller. The product of the plastic film manufacturer That is, the production is completed.
In the application of thick clear plastic sheeting rolls, the most fearful is the windy weather, it is easy to scratch it, so I want to improve the wind resistance of the plastic film, and can adjust the installation time of the thick transparent plastic film roll to delay the aging speed.
