Many people may be confused, and it is true that ordinary people do not know about the degradable function. Today, I will give you an inventory and analysis of several different degradation methods of degradable lunch boxes. Let’s take a look together!
1. Biodegradation. The blending and copolymerization of natural polymers and general-purpose synthetic polymers is biodegradation. Biodegradation refers to the degradation process achieved through the erosion and decomposition of microorganisms. A good brand of fully degradable lunch boxes recommends that most pure polymers have a strong anti-microbial erosion ability due to the particularity of their molecular structure, and are not easily decomposed by microorganisms. However, if additives such as plasticizers and antioxidants are added to the polymers, it can be reduced Its anti-corrosion effect. Because of the different degradation pathways, biodegradation can be divided into two types: biochemical degradation and biophysical degradation.
2. Photo-biodegradation, photo-biodegradation is the combined application of the photodegradation mechanism of photodegradation and the biodegradation mechanism of biodegradation. The fusion of photodegradation and biodegradation makes up for the shortcomings of photodegradation and biodegradation. For example, the degradation process of photo-biodegradation is no longer restricted by the degree of light. Which trustworthy fully degradable lunch box can quickly degraded, and degraded completely.
3. Photodegradation, photodegradation refers to the fully degradable lunch box through the action of light. The polymer molecular chains in this type can stimulate electronic activity under the irradiation of ultraviolet light and other light, and then photochemical reactions occur. Under the influence of O2, photooxygen degradation can eventually occur. Under photochemical action, the photodegraded polymer chains lose their strength due to damage, and the material becomes brittle, and is further brittle under the action of wind, rain and other natural environments, and finally decomposes into powder and blends into the soil to enter a new round. biological cycle.
The degradation methods of degradable lunch boxes mainly include biodegradation, photo-biodegradation, photodegradation, etc. The specific principles of these different explanation methods have been introduced to you above, although degradable lunch boxes can relieve There is a certain amount of environmental pressure, but we still need to work harder from everyone.
