The ideal biodegradable plastic bag made of biodegradable material is a kind of biodegradable plastic bag with excellent performance. After being discarded,Biodegradable clothes bags it can be completely decomposed by environmental microorganisms, and finally converted into CO2 and H2O to become the carbon cycle in nature,Biodegradable clothes bags biodegradable plastic The decomposition of the bag is mainly through the action of microorganisms. Therefore,Biodegradable clothes bags the degradation mechanism of biodegradable materials is the process of digestion and absorption of materials by bacteria and bacteria.
First, microorganisms secrete hydrolase in vitro to bind to the surface of the material,Biodegradable clothes bags cut off the polymer chains on the surface through hydrolysis,Biodegradable clothes bags and generate small molecular weight compounds, and then the degraded products are taken into the body by the microorganisms,Biodegradable clothes bags and undergo various metabolic routes to synthesize microorganisms or transform. It is the energy for microbial activities,Biodegradable clothes bags which is finally converted into CO2 and H2O[4]. According to the chemical nature of its degradation,Biodegradable clothes bags it is divided into hydrolysis and enzymatic hydrolysis.
Biodegradable plastic bags have the following characteristics: (1) It can be treated together with garbage, or can be made into compost to return to nature; (2) Due to degradation,Biodegradable clothes bags its volume is reduced and the life of the landfill is extended; (3) No There is a problem that ordinary plastic bags need to be incinerated, which can inhibit the emission of harmful gases; (4) It can reduce the harm to wild animals and plants caused by random disposal; (5) It is convenient to store and transport,Biodegradable clothes bags as long as it is kept dry and does not need to be protected from light;Biodegradable clothes bags (6) Application Wide range, not only can be used in agriculture and packaging industries,Biodegradable clothes bags but also in the medical industry.
