3. The lactic acid is then converted intolactide, a ring-form dimer of lactic acid.These lactide molecules bond together to create polymers. 4. The result of the polymerizationis small pieces of raw material polylactic acid plastic which can be converted into an array of PLA plastic products....
PLA is a new type of biodegradable material, made from starch raw materials proposed by 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 certa...
