Poly (lactic acid) has good thermal stability, processing temperature 170~230℃, good solvent resistance, can be processed in a variety of ways, such as extrusion, spinning, biaxial stretching, injection blow molding. In addition to biodegradation, polylactic acid products have good biocompatibility, gloss, transparency, feel and heat resistance, as well as certain bacteria resistance, flame retardant and uv resistance, so they are widely used as packaging materials, fibers and nonwovens. At present, it is mainly used in clothing (underwear, outerwear), industry (construction, agriculture, forestry, paper making) and medical and health fields.
PLA has many applications in extrusion, injection molding, film drawing, spinning and other fields.
1) materials
Husk crops such as corn are crushed to extract starch, which is then turned into unrefined glucose. Many advanced technologies have now eliminated the crushing process and extracted material directly from a large number of crops.
2) fermentation
Glucose is fermented in a manner similar to that used to produce beer or alcohol. Glucose is then fermented into lactic acid, which is added to food and used in muscle tissue.
3) Intermediate products
Lactic acid monomer with a special concentration process, into an intermediate product - reduced water lactic acid, that is, lactide.
4) polymerization
Lactide monomer after vacuum purification, and then in a solvent - free solution process to complete the ring-opening action, so that the monomer polymerization.
5) Polymer modification
Due to the difference of molecular weight and crystallinity of polymer, there is a large room for material properties to change, so PLA is modified differently for different products.
