可降解颗粒塑料是什么原料:可降解塑料有两种,一种是以聚乙烯塑料为主,掺入淀粉等生物降解剂制成的塑料袋,又称生物降解塑料袋。这种塑料袋主要靠微生物的效果分化。另一种是以聚乙烯塑料为主,掺入轻分化剂和碳酸钙等矿粉制成的塑料袋,又称光降解塑料袋。这类塑料袋在阳光效果下分化,降解塑料是指在出产过程中参加一定量的添加剂,稳定性下降,在塑料的自然环境中更简单降解。

What are the raw materials of degradable granular Plastics: there are two kinds of degradable plastics. One is a plastic bag mainly made of polyethylene and mixed with biodegradable agents such as starch, also known as biodegradable plastic bag. This plastic bag is mainly differentiated by the effect of microorganisms. The other is a plastic bag mainly made of polyethylene plastic mixed with light differentiation agent, calcium carbonate and other mineral powder, also known as photodegradable plastic bag. This kind of plastic bag is differentiated under the effect of sunlight. Degradable plastic refers to the addition of a certain amount of additives in the production process, which reduces the stability and makes it easier to degrade in the natural environment of plastic.
可降解塑料出产方法为树脂+光敏剂+光降解调节剂或树脂+生物降解材料+光敏剂+其他
The production method of degradable plastics is resin + photosensitizer + photodegradation regulator or resin + biodegradable material + photosensitizer + others
光降解机理如下:光降解剂是一种具有过渡金属元素和双键的有机化合物。在光照下,产生光化学反应生成自由基化合物,将氢转移到聚合物分子上,使分子链断裂,从而实现聚合物降解。光降解剂可分为两类:过渡金属化合物(配合物)和二苯甲酮类化合物。
The photodegradation mechanism is as follows: photodegradant is an organic compound with transition metal elements and double bonds. Under light, photochemical reaction is generated to generate free radical compounds, which transfer hydrogen to polymer molecules and break the molecular chain, so as to realize polymer degradation. Photodegradants can be divided into two categories: transition metal compounds (complexes) and benzophenone compounds.
生物降解的机理是:生物降粘剂能够使用细菌、真菌、放线菌的效果,依靠生物细胞的生长,使塑料制品产生机械失效,或通过微生物效果于聚合物而产生新的物质、塑料成分,或单纯的侵蚀产生霉变,导致塑料分裂、氧化、断链。生物降解剂主要是玉米、马铃薯、谷物等淀粉类。
The mechanism of biodegradation is: biological viscosity reducer can use the effect of bacteria, fungi and actinomycetes, rely on the growth of biological cells, make plastic products produce mechanical failure, or produce new substances and plastic components through microbial effect on polymers, or simply erode and produce mildew, resulting in plastic splitting, oxidation and chain breaking. Biodegradable agents are mainly corn, potato, grain and other starch.
光降解/生物降解塑料是在地面上暴露在阳光下,依据光降解机理产生光降解的塑料制品。当塑料制品在地下土壤中时,它们会依据生物降解机制进行生物降解。一般来说,一切塑料在一定条件下都会降解。可降解塑料是指在出产过程中参加一定量的添加剂,因为稳定性降低,在自然环境中简单降解的塑料。
Photodegradable / biodegradable plastics are plastic products that are exposed to sunlight on the ground and produce photodegradation according to the photodegradation mechanism. When plastic products are in underground soil, they will be biodegraded according to the biodegradation mechanism. Generally speaking, all plastics will degrade under certain conditions. Degradable plastics refer to plastics that are simply degraded in the natural environment due to the reduction of stability by adding a certain amount of additives in the production process.
