Description

Production process and production equipment of environment-friendly degradable plastic shopping bag
Technical Field
The invention relates to the field of degradable plastics, in particular to a production process and production equipment of an environment-friendly degradable plastic shopping bag.
Background
Plastics are synthetic high molecular compounds, which are materials polymerized by using monomer raw materials through synthesis or condensation reaction. In daily life, plastic products have penetrated the aspects of our life, and various plastic products bring convenience to our life, but most of plastics are difficult to degrade, so that a large amount of white garbage is generated after the plastics are discarded, and great harm is generated to the ecological environment and animals and plants in the nature. And because raw material petroleum for manufacturing traditional plastics is a precious non-renewable resource, the raw material petroleum is exhausted along with the mass use of human beings. Degradable plastics are plastics whose chemical structure changes significantly under specific environmental conditions and whose material property changes can be determined by standard test methods. After the degradable plastic is discarded, the degradable plastic can be degraded by using certain factors in the environment, so that the accumulation of the plastic waste in the environment can be reduced. Therefore, the biodegradable material is used for replacing traditional film resin such as polyethylene and the like which are difficult to degrade, and the biodegradable material is a main means for radically treating 'white pollution' of the film.
According to the environment condition of degradation, the degradable plastics can be divided into three categories: photodegradable plastics, biodegradable plastics and photo-biodegradable plastics. The photodegradable plastic is degraded and decomposed under the irradiation of sunlight, cracks appear on the surface of the material, the mechanical property is seriously reduced, and then the material is broken, so that the purpose of decomposition is achieved. Biodegradation refers to degradation and assimilation of plastics by physical, chemical or biological action of microorganisms (mainly fungi, bacteria and algae) in natural environment without polluting soil. Although photodegradable plastics degrade and decompose under the irradiation of sunlight, macromolecular polyester decomposes slowly, and biodegradable plastics degrade rapidly, but the mechanical properties and the processing characteristics of the biodegradable plastics cannot meet the daily use, so that a novel photodegradable-biodegradable plastic is needed to meet the production of degradable plastic shopping bags, and a matched plastic bag processing device is also needed to further improve the bag making efficiency and improve the productivity.
