Rauemi Whakarerekehia te werohanga werohanga biodegradable

He maha nga huarahi ahumahi ka taea te whakamahi (ara te taumaha ngota teitei) PLA.E rua nga monomers matua e whakamahia ana: te waikawa lactic, me te cyclic di-ester, lactide.Ko te huarahi tino noa ki te PLA ko te polymerization whakakai-whakatuwhera o te lactide me nga momo whakakōkī whakarewa (te nuinga o te tiihi octoate) i roto i te otinga, hei whakatārewa ranei.Ko te tauhohenga whakarewa-catalyzed e kaha ana ki te whakatiki i te PLA, ka whakaiti i te ahua o te ahua o te ahua ki te mea timatanga (te nuinga o te wa ko te maaka witi).

He wairewa te PLA i roto i nga momo whakarewa pararopi.Ko te Ethyl acetate, na te ngawari o te uru me te iti o te tupono ki te whakamahi, he tino painga.Ka memeha te kakawaua pūreretā PLA 3D ina rukuhia ki te ethyl acetate, ka waiho hei whakarewa whai hua mo te horoi i nga upoko extruder tā 3D, te tango ranei i nga tautoko PLA.He iti te ira kohua o te ethyl acetate ki te maeneene hoki i te PLA i roto i te ruuma kohu, he rite ki te whakamahi i te kohu acetone ki te maeneene ABS.

Ko etahi atu whakarewa haumaru hei whakamahi ko te propylene carbonate, he haumaru ake i te ethyl acetate engari he uaua ki te hoko hokohoko.Ka taea hoki te whakamahi Pyridine engari he iti ake te haumaru i te ethyl acetate me te propylene carbonate.He kakara kino ano te ika.
