CHINAPLAS has become Asia's No.1 and world's leading plastics and rubber trade fair. The 34th edition of CHINAPLAS held on April 13-16, 2021 at National Exhibition and Convention Center Shenzhen, PR China.
YAOAN showed its new designed PLA sheet machine , capacity of 400-500kgs/hr
Introduction of the production line:
It is used in the production of PET and PLA sheets without pre-crystallization and drying system, and is suitable for the production of recycled materials. It has the characteristics of high output, low energy consumption and excellent plasticization.
The screw is of modular design , has multiple combinations, and a wide range of applications. It is not only suitable for PLA biodegradable materials and starch-based degradable materials, but also suitable for PET production.
The barrel is equipped with double vacuum exhaust to ensure full exhaust of water vapor.
The extruder is equipped with a melt pump for quantitative and stable output, and set the pressure and speed closed-loop autocontrol.
The whole line adopts PLC control to realize the autocontrol of parameter setting, data operation and feedback, alarm and other functions.
Extruded sheet application fields:
Polylactic acid (PLA) is a new type of biodegradable material, made from starch raw materials , which is extracted from renewable plant resources (such as corn). Starch raw materials are saccharified to obtain glucose, which is then fermented by glucose and certain strains to produce high-purity lactic acid, and then a certain molecular weight polylactic acid is synthesized through chemical synthesis. It has good biodegradability, can be completely degraded by microorganisms in nature after use, and finally form carbon dioxide and water without polluting the environment. This is very beneficial to environmental protection and is recognized as an environmentally friendly material.
