Kedu ihe bụ PLA?

A na-emepụta PLA, ma ọ bụ polylactic acid site na shuga ọ bụla na-agba agba.Ọtụtụ PLA sitere na ọka n'ihi na ọka bụ otu n'ime shuga dị ọnụ ala na nke kachasị dị n'ụwa niile.Otú ọ dị, okpete, mgbọrọgwụ tapioca, akpu, na sugar beet pulp bụ nhọrọ ndị ọzọ.

Kedu ka esi eme ngwaahịa PLA?

Nzọụkwụ bụ isi iji mepụta polylactic acid sitere na ọka bụ ndị a:

1. A ga-agbanwe starch ọka mbụ ka ọ bụrụ shuga site na usoro a na-akpọ igwe igwe mmiri.Igwe igwe mmiri na-ekewa starch na ndụ.A na-agbakwunye acid ma ọ bụ enzymes ozugbo ekewapụrụ ihe ndị a.Mgbe ahụ, ha na-ekpo ọkụ ka ha gbanwee starch n'ime dextrose (aka sugar).

2. Na-esote, dextrose na-agbakọta.Otu n'ime ụzọ gbaa ụka na-agụnye ịgbakwunyeLactobacillusnje bacteria na dextrose.Nke a, n'aka nke ya, na-emepụta lactic acid.

3. A na-agbanwezi lactic acid ka ọ bụrụ lactide, mgbanaka ụdị mgbanaka nke lactic acid.Mkpụrụ ndụ lactide ndị a jikọtara ọnụ iji mepụta polymers.

4. N'ihi nke polymerization bụ obere iberibe raw ihe polylactic acid plastic nke nwere ike converted n'usoro nke.Ngwaahịa plastik PLA.
