Problems solved by technology

[0002] Plastic film is a common daily necessities for people nowadays. Plastic film has the advantages of good transparency, good moisture resistance, excellent heat resistance, convenient use, and low price. It is widely used in various industries, but the plastic film currently on the market is mainly based on Polyethylene plastic film is mainly used, which brings serious pollution to the environment. It is also called "white pollution" because of its refractory property, and it will release harmful gas itself, which poses a threat to people's health. The invention discloses a The production process of plastic film, which uses biodegradable resin as the main raw material, mixes processing aids, biodegradation aids, dispersion aids, and photosensitizers in a certain proportion, and processes them into plastic films under certain conditions. The film can be degraded by microorganisms, and the degradation speed is faster under the condition of light, which eliminates the environmental pollution caused by plastic film, but its production conditions are not clear, whether the equipment technology can meet the requirements is unclear, and whether the production can achieve the expected effect is uncertain ensure

Abstract

The invention relates to a production technology of a plastic film, and belongs to the technical field of plastic films. The production technology of the plastic film comprises the following steps of1, screening raw materials; 2, melting the raw materials; 3, adding the melted raw materials into a film blowing machine and blowing out a film; 4, cooling the film; 5, conducting corona treatment; 6,removing electricity and dust; 7, conducting spraying; 8, conducting drying; 9, cutting waste edges and coiling the film. According to the production technology of the plastic film, a free radical reaction is generated on the surface of the plastic film through corona treatment, so that a polymer is crosslinked, the surface becomes rough, the wettability of the polymer to a polar solvent is improved, and plasmas enter the surface of a printed object through electric shock and penetration to destroy the molecular structure of the printed object, so that molecules of the treated surface are oxidized and polarized; ion electric shock erodes the surface, so that the adhesion capability of the surface of printing stock is improved, and the quality of subsequent spraying is improved.
