Bophelong ba rona ba letsatsi le letsatsi, lihlahisoa tsa polasetiki li fumaneha hohle.Leha ho le joalo, mathata a ntseng a eketseha a tikoloho a bakoang ke lipolasetiki tsa setso a entse hore batho ba batle mekhoa e meng e tšoarellang haholoanyane.Mona ke moo bioplastic e kenang teng.Har'a bona, starch ea poone e bapala karolo ea bohlokoa e le karolo e tloaelehileng ho bioplastics.Joale, hantle-ntle mosebetsi oacornstarch ka bioplastics?
1.Li-Bioplastics ke eng?
Bioplastics ke polasetiki e entsoeng ka lisebelisoa tse ka nchafatsoang joalo ka limela kapa likokoana-hloko.Ho fapana le lipolasetiki tsa setso, li-bioplastics li entsoe ka lisebelisoa tse nchafalitsoeng, ka hona li baka tšusumetso e fokolang ea tikoloho.Setache sa poone, har'a bona, hangata se sebelisoa e le e 'ngoe ea likarolo tsa mantlha tsa bioplastics.
2.Seabo sa Corn Starch ho Bioplastics
Corn starch e sebeletsa mesebetsi e meraro e meholo:
Cornstarch e bapala karolo ea ho ntlafatsa, ho tsitsisa le ho ntlafatsa thepa ea ts'ebetso ho bioplastics.Ke polymer e ka kopanngoang le li-polymers tse ling tse senyehang kapa li-plasticizers ho theha meaho e tsitsitseng.Ka ho kenyelletsa litlatsetso tse nepahetseng ho starch ea poone, ho thatafala, ho tenyetseha le sekhahla sa ho senyeha ha bioplastics li ka fetoloa, tsa etsa hore li tšoanele maemo a fapaneng a ts'ebeliso.
Ntlafatso ea Matla a Mechini: Ho kenyelletsoa ha starch ea poone ho ka ntlafatsa ho tiea le ho tiea ha bioplastics, ho etsa hore e tšoarelle haholoanyane.
Ntlafatso ea Ts'ebetso ea Ts'ebetso: Ho ba teng ha starch ea poone ho etsa hore bioplastic e be bonolo haholoanyane nakong ea ts'ebetso, e nolofalletsa tlhahiso ea lihlahisoa tse fapaneng tse nang le libopeho.
Ho feta moo, starch ea poone e na le biodegradability e ntle haholo.Tlas'a maemo a loketseng a tikoloho, likokoana-hloko li ka arola starch ea poone hore e be metsoako e bonolo ea manyolo, 'me qetellong e fihlele ho senyeha ho feletseng.Sena se lumella bioplastics hore e sebelisoe hape ka tlhaho kamora ho sebelisoa, ho fokotsa tšilafalo ea tikoloho.
Leha ho le joalo, starch ea poone e boetse e na le mathata a mang.Mohlala, libakeng tse nang le mocheso o phahameng kapa mongobo o phahameng, li-bioplastics li na le tšekamelo ea ho lahleheloa ke botsitso, tse amang nako ea tsona ea bophelo le ts'ebetso ea tsona.Ho rarolla bothata bona, bo-rasaense ba ntse ba sebetsa ho fumana li-additives tse ncha kapa ho ntlafatsa mekhoa ea tlhahiso ho matlafatsa ho hanyetsa mocheso le ho hanyetsa mongobo oa bioplastics.
3.Likopo tsa Corn Starch ho Specific Bioplastics
Tšebeliso ea starch ea poone ho bioplastic e khethehileng e fapana ho latela thepa e lakatsehang le ts'ebeliso e reriloeng ea sehlahisoa sa ho qetela.Mehlala e seng mekae ke ena:
Polylactic Acid (PLA): PLA ke bioplastic e atisang ho tsoa ho starch ea poone.Setache sa poone se sebetsa e le phepelo bakeng sa tlhahiso ea lactic acid, e ntan'o etsoa polymer ho theha PLA.PLA e matlafalitsoeng ka starch ea poone e bonts'a thepa e ntlafalitsoeng ea mochini, joalo ka matla a thata le ho hanyetsa tšusumetso.Ho feta moo, tlatsetso ea starch ea poone e ka ntlafatsa biodegradability ea PLA, ea e etsa hore e tšoanelehe bakeng sa lits'ebetso moo ho amehang tikoloho, joalo ka.moroho o lahliloeng, ho paka lijo, le lifilimi tsa temo tsa mulch.
Polyhydroxyalkanoates (PHA): PHA ke mofuta o mong oa bioplastic o ka hlahisoang ho sebelisoa starch ea poone e le mohloli oa carbon.Setache sa poone se belisoa ke likokoana-hloko ho hlahisa polyhydroxybutyrate (PHB), e leng mofuta oa PHA.Li-PHA tse matlafalitsoeng ka starch ea poone li na le botsitso bo betere ba mocheso le thepa ea mochini.Li-bioplastic tsena li fumana lits'ebetso makaleng a fapaneng, ho kenyeletsoa ho paka, lisebelisoa tsa bongaka le temo.
Li-Bioplastics tse thehiloeng ho Starch: Maemong a mang, starch ea poone e sebetsoa ka kotloloho ho bioplastics ntle le tlhoko ea mehato e eketsehileng ea polymerization.Li-bioplastics tse thehiloeng ho starch hangata li na le motsoako oa starch ea poone, li-plasticizers le li-additives ho ntlafatsa ts'ebetso le lisebelisoa tsa ho qetela.Li-bioplastics tsena li sebelisoa lits'ebetsong tse joalo ka mekotla e lahloang, lijana tsa lijo, le lisebelisoa tsa tafole tse lahloang.
Ho Kopana le Li-polymers tse ling tse ka senyehang: starch ea poone e ka boela ea kopanngoa le li-polymers tse ling tse ka senyehang, tse kang polyhydroxyalkanoates (PHA), polycaprolactone (PCL), kapa polybutylene adipate-co-terephthalate (PBAT), ho etsa bioplastic e nang le thepa e hlophisitsoeng.Metsoako ena e fana ka tekanyo ea matla a mochini, ho tenyetseha, le biodegradability, e etsa hore e tšoanelehe bakeng sa lits'ebetso tse fapaneng ho tloha ho liphutheloana ho isa ho tsa temo.
4.Qetello
Karolo ea starch ea poone ho bioplastics e feta ho ntlafatsa ts'ebetso;e boetse e thusa ho fokotsa ho itšetleha ka lipolasetiki tsa setso tse entsoeng ka peterole, ho tsamaisa nts'etsopele ea lisebelisoa tse sa sebeliseng tikoloho.Ka tsoelopele ea theknoloji, re lebelletse ho bona lihlahisoa tse ncha tsa bioplastic tse ipapisitseng le lisebelisoa tse ka nchafatsoang joalo ka starch ea poone.
Ka bokhutšoanyane, starch ea poone e bapala karolo e ngata ho bioplastics, eseng feela ho ntlafatsa botsitso ba sebopeho sa polasetiki empa hape le ho khothaletsa ho senyeha ha tsona, ka hona ho fokotsa tšusumetso ea tikoloho.Ka tsoelo-pele e tsoelang pele ea theknoloji le boqapi, bioplastic e mothating oa ho bapala karolo e kholo ho tlisa melemo e mengata tikolohong ea rona ea Lefatše.
