可降解塑料的主要应用领域有农用地膜、各类塑料包装袋、垃圾袋、商场购物袋以及一次性餐饮具等
The main application fields of degradable plastics include agricultural mulch, various plastic packaging bags, garbage bags, shopping bags in shopping malls, and disposable catering utensils
试验表明,大多数可降解塑料在一般环境中暴露3个月后开始变薄、失重、强度下降,逐渐裂成碎片。如果这些碎片被埋在垃圾或土壤里,则降解效果不明显。
The test shows that most degradable plastics begin to thin, lose weight, decrease strength and gradually break into pieces after being exposed to general environment for 3 months. If these fragments are buried in garbage or soil, the degradation effect is not obvious.
聚乳酸(PLA)是一种新型的生物降解材料,使用可再生的植物资源(如玉米)所提出的淀粉原料制成。玉米淀粉原料经由发酵过程制成乳酸,再通过化学合成转换成聚乳酸。其具有良好的生物可降解性,使用后能被自然界中微生物完全降解,生成二氧化碳和水,不污染环境.
Poly (lactic acid) (PLA) is a new type of biodegradable material, which is made from starch raw materials proposed by renewable plant resources (such as corn). Corn starch raw material is made into lactic acid through fermentation process, and then converted into polylactic acid through chemical synthesis. It has good biodegradability. After use, it can be completely degraded by microorganisms in nature to generate carbon dioxide and water without polluting the environment
PLA聚乳酸在常温下性能稳定,但在温度高于550C的弱碱性或富氧条件下在微生物的作用下会自动降解。使用后它能被自然界中微生物完全降解,终生成二氧化碳和水,而且不像传统的石油基塑料会增加二氧化碳的释放,聚乳酸在降解过程中产生的二氧化碳,可再次被使用成为植物进行光合作用所需的碳原子。
PLA polylactic acid has stable performance at room temperature, but it will degrade automatically under the action of microorganisms under the weak alkaline or oxygen-enriched conditions with temperature higher than 550C. After use, it can be completely degraded by microorganisms in nature and eventually generate carbon dioxide and water, and unlike traditional petroleum-based plastics, which will increase the release of carbon dioxide, the carbon dioxide generated in the degradation process of polylactic acid can be used again as carbon atoms required for photosynthesis of plants.
平行双螺杆风冷拉条切粒系统是由:风冷钢丝网输送带和切粒机组成
The parallel twin-screw air-cooled draw bar pelletizing system is composed of: air-cooled wire mesh conveyor belt and pelletizer
PLA可降解塑料风冷拉条切粒机的原理 :
The principle of PLA degradable plastic air-cooled strip cutter:
平行双螺杆挤出机挤出PLA可降解塑料条子,掉在风冷钢丝网输送带上。输送带上面有十多个风扇将挤出的塑料条通过一个个风扇进行风冷,再送到切粒机里。完成风冷拉条的造粒。
Parallel twin-screw extruder extrudes PLA degradable plastic strips and falls on the air-cooled steel mesh conveyor belt. There are more than ten fans on the conveyor belt to air cool the extruded plastic strips through one fan and then send them to the granulator. Complete the granulation of air-cooled braces.
