Polyhydroxyalkanoate PHA

Polyhydroxyalkanoate e khutsufalitsoeng e le PHA, ke lentsoe le akaretsang bakeng sa sehlopha sa li-polyester tse boima ba limolek'hule tse entsoeng ke likokoana-hloko. PHA e entsoe ka poone, litapole le biomass tse ling tse thehiloeng ho starch kapa lehlaka selulose e le lisebelisoa tse tala, tse lomositsoeng ho hlahisa lactic acid, 'me li hloekisoa le ho etsoa polymerized ho lokisetsa PLA e hloekileng, e nang le botsoalle ba tikoloho, e se nang chefo, e thibelang likokoana-hloko, lelakabe. e liehang le e ntle ea biocompatibility.

Kereiti ea ho bopa ente ea PHA, sehlopha sa blister, sehlopha sa filimi ea blow, foam, le lisebelisoa tse ling tse senyehang ka botlalo moleng oohle. PHAs ke mofuta oa lintho tse entsoeng ka polyhydroxyalkanoates (PHA), e leng biopolymer e entsoeng ka kotloloho ka ho belisoa ha likokoana-hloko ka har'a likokoana-hloko. Li-PHA li na le thepa ea boleng bo holimo joalo ka biocompatibility, biodegradability, le thepa ea piezoelectric. Ba na le lisebelisoa tse ntle tsa ts'ebeliso le lisebelisoa, 'me thepa ea bona ea motheo e tšoana le polypropylene. Li ka sebetsoa le ho bōptjoa ho sebelisoa lisebelisoa tsa khale tsa ho lokisa polasetiki tse kang ho etsa ente, extrusion, ho butsoela filimi, ho taka terata, le ho bōptjoa, 'me li ka nka sebaka sa boholo ba lipolasetiki tse thehiloeng peterole. Sekhahla sa biodegradation sa PHAs se ka laoloa ke sebopeho sa li-copolymer tsa tsona ho latela litlhoko tse fapaneng tsa ts'ebeliso.
