The two methods of degradation of plastic film on PE blown film machine have different characteristics due to their great differences in process flow. According to experts, the process solution casting method is relatively simple, but not easy to control the quality of the products, the film is low, high energy consumption, equipment investment is large; and the method of blown film extrusion in product quality and production efficiency, significantly improved than casting method.
With the development of society, more and more attention has been paid to the packaging of products, and the packaging of film has become a major concern. Because the use of film packaging can make the product preservation performance lasting, but also with moisture, frost, oxygen, oil and other functions, so that people like it more and more.
Film blowing machine production process is firstly added polyethylene particles drying hopper, then particles by their own weight from the hopper into the screw thread, when the screw and the oblique edge contact, the rotation of the face of the plastic face aslant vertical thrust and aslant, the particle goes forward.
PE film blowing machine in diameter lining or casting wear-resistant alloy alloy steel in order to save precious than large extruder barrel used in casting key molding, and then in the finishing hole after the Canucks wear-resistant alloy bushing or cast a layer of wear-resistant alloy material. PE film blowing machine blown film opaque system, may also be in the extrusion process, the extrusion temperature is too low, raw materials such as resin formation caused by crystallization, the transparency of the film affected by such a situation, we need to adjust the extrusion temperature, extrusion temperature increase, reduce the formation of crystal.
