BBCA polylactic acid e apara lihlahisoa tse ncha

Polylactic acid (PLA) ke mofuta oa thepa e ncha e hlahisoang ke polymerization e eketsehileng ea lactic acid ho tloha ho starch kapa ho belisoa ha tsoekere. Ha e sebelise petroleum e le lisebelisoa tse tala, 'me e na le litšobotsi tsa ts'ireletso ea tikoloho, e seng chefo, antibacterial, retardant ea mollo, biocompatibility e ntle le biodegradability. Ke thepa e ncha e tšepisang ka ho fetisisa ho sisinya boemo ba setso ba lipolasetiki tse thehiloeng ho petroleum le likhoele tsa lik'hemik'hale nakong e tlang.

Polylactic acid le lihlahisoa tsa eona li na le thepa e tsitsitseng ea 'mele tlas'a maemo a tloaelehileng a mocheso le mongobo. Ke biomaterial e senyehang ka ho felletseng, e ka sebelisoang hape. Ka mor'a ho lahloa, e ka fetoloa carbon dioxide le metsi. Ka mor'a photosynthesis ke limela, e ka monngoa ke limela hape 'me ea kena ka har'a selikalikoe sa tlhaho ka ho sa feleng. Ke "thepa ea ho tsosolosa tikoloho ea lekholong la bo21 la lilemo".

Litšobotsi tse ka sehloohong ke tse latelang

(1) mehloli e ka nchafatsoang: haholo-holo ho tsoa ho poone, litapole le lijalo tse ling tsa starch, hammoho le joang ba lijalo, joalo-joalo;

(2) biodegradation e feletseng: e ka monngoa le ho sebelisoa ke 'mele oa motho; lihlahisoa li senyeha ka ho feletseng ho CO2 le H2O mobung kapa metsing a leoatle ka mor'a ho lahleloa ka har'a mobu nakong ea selemo se le seng, ho lemoha potoloho ea carbon holim'a metsi le ho fetola ka katleho tšilafalo ea tikoloho e bakoang ke lisebelisoa tse thehiloeng ho petroleum;

(3) kamano ea 'mele oa motho le tšireletseho: lactic acid e tala e fumaneha' meleng oa motho, PLA e ka tšeloa 'me ea kenngoa ke' mele oa motho, PLA ke FDA e tiisitsoeng ke FDA, e 'nileng ea sebelisoa haholo lefapheng la bongaka ka lilemo tse mashome;

(4) ts'ebetso e ntle haholo: e ka sebetsoa ka mekhoa e mengata, joalo ka extrusion, spinning, biaxial drawing, ente blow molding;

(5) antibacterial le anti mite ea tlhaho: tekanyo ea antibacterial le anti mite ea Candida albicans, Escherichia coli le Staphylococcus aureus e fihlile ho feta 95%;

(6) ho lieha ha lelakabe la tlhaho: ho sireletseha le ho thibela lelakabe, mosi o fokolang, ha ho na mosi o motšo le khase e chefo;

(7) gloss e ntle haholo, pepeneneng, sebetsana, ho hanyetsa UV, conductivity ea mongobo, ha ho na mongobo hape, joalo-joalo.

Asiti ea polylactic e ka etsoa fiber ea polylactic acid, 'me ts'ebetso ea eona e tšoana le ea k'hothone. Ho phaella moo, polylactic acid e na le ts'ebetso e ts'oanang le lisebelisoa tsa lik'hemik'hale tse tloaelehileng tse kang polypropylene (PP), polyethylene (PE), likhoele tsa polyester (PET, PTT, PBT). E ka sebetsoa ka ho bopeha ka ente, extrusion, spinning le mekhoa e meng ea ho etsa likhoele, lifilimi, lishiti le lipoleiti, butle-butle ho nkela likhoele tsa Petrochemical le polasetiki ea peterole, E sebelisoa haholo liaparo, liphutheloana, temo, lehae, likarolo tsa koloi, khatiso ea 3D, biomedicine le masimo a mang a mangata.
