Li-biopolymer tsa tlhaho: Bokamoso ba thepa e mosa tikolohong
Pendahuluan
Mehleng ena ea temoso e ntseng e eketseha ea tikoloho, tšebeliso ea thepa e sireletsang tikoloho e se e le ntho ea bohlokoa haholo masimong a fapaneng, ho tloha tlhahisong ea indasteri ho ea lihlahisoa tsa letsatsi le letsatsi tsa bareki. Tharollo e 'ngoe e hohetseng tlhokomelo ke li-biopolymer tsa tlhaho. Li-biopolymer tsa tlhaho li fana ka mokhoa o mong o khahlang ho feta polasetiki ea setso, e thehiloeng peteroleng e seng mosa ho tikoloho. Sengoloa sena se tla hlahloba ka botlalo hore na li-biopolymer tsa tlhaho ke eng, mefuta ea tsona, lits'ebetso le melemo.
Li-biopolymer tsa Organic ke Eng?
Li-biopolymer tsa tlhaho ke mofuta oa polymer e nkiloeng mehloling ea tlhaho 'me e ka bola ka tlhaho. Ho fapana le li-polymer tsa maiketsetso tse kang polasetiki e tloaelehileng, tse nkang lilemo tse makholo ho isa ho likete ho bola, li-biopolymer tsa tlhaho li ka senyeha ka potlako tikolohong. Mehloli e meholo ea li-biopolymer tsa tlhaho e kenyelletsa metsoako e fumanoang limela, liphoofolo le likokoana-hloko. Mehlala e tloaelehileng ea li-biopolymer tsa tlhaho ke polylactide (PLA), poly-3-hydroxybutyrate (PHB), le chitosan.
Mefuta ea Li-biopolymer tsa Organic
1. Polylactide (PLA)
– Mohloli: PLA e hlahisoa ka ho belisa starch ho tsoa limela tse kang poone le 'moba.
– Melemo: E bola habonolo ebile e na le thepa e ntle ea mechini, PLA e sebelisoa liphuthelong tsa lijo, lisebelisoa tsa bongaka le lihlahisoa tsa bareki.
2. Poly-3-hydroxybutyrate (PHB)
– Mohloli: PHB e hlahisoa ke dikokwana-hloko tse fapaneng ka mokhoa wa ho belisa.
– Melemo: E lumellana haholo le lintho tse phelang 'me e bola kapele. PHB e sebelisoa merianang ea biomedicine le liphuthelong.
3. Chitosan
– Mohloli: Se ntšitsoeng ho tsoa likhetleng tsa crustacean tse kang shrimp le crab.
– Melemo: E na le thepa ea ho loantša likokoana-hloko le ea ho bolaea likokoana-hloko, e leng se etsang hore e be ntle bakeng sa ts'ebeliso mafapheng a bongaka le a litlolo.
4. Selulose
– Mohloli: E fumaneha maboteng a sele ea limela.
– Melemo: E ngata haholo 'me e ka sebelisoa lits'ebetsong tse fapaneng tse kang masela, pampiri le thepa e kopaneng.
Litšebeliso tsa Li-biopolymer tsa Organic
Tsoelo-pele ea theknoloji e butse mefuta e mengata ea lits'ebetso bakeng sa li-biopolymer tsa tlhaho. Mona ke tse ling tsa makala a bohlokoa a sebelisang li-biopolymer tsena ka mafolofolo hona joale.
1. Sephutheloana
– Tšebeliso ea li-polymer tse kang PLA le PHB liphuthelong tsa lijo e se e tumme haholo. Lik'hamphani tse 'maloa tse kholo tsa lijo li qala ho fetohela ho liphuthelong tse thehiloeng ho biopolymer ho eketsa boleng bo sireletsang tikoloho lihlahisoa tsa tsona.
2. Bongaka le Bongaka ba Likokoana-hloko
– Chitosan e sebediswa ho etseng masela a thibelang dikokwana-hloko le masela a thibelang maqeba. PLA le PHB le tsona di sebediswa ho etseng disebediswa tsa ho buoa le di-implant ka lebaka la ho se lekane ha tsona mmeleng.
3. Masela
– Cellulose le PLA li ntse li sebelisoa ka ho eketsehileng indastering ea masela ho hlahisa masela a sa sireletseng tikoloho feela empa hape a phutholohang ho a apara.
4. Temo
– Li-biopolymer li sebelisoa ho hlahiseng lifilimi tsa mulch tse ka bolang tse ka thusang ho holisa limela hantle ha ka nako e ts'oanang li fokotsa tšusumetso ea tikoloho.
Melemo ea Li-biopolymer tsa Organic
1. E mosa ho Tikoloho
– Molemo o moholo oa li-biopolymer tsa tlhaho ke bokhoni ba tsona ba ho bola ka tlhaho, ka hona li fokotsa moroalo oa litšila tsa polasetiki tikolohong.
2. Lisebelisoa tse tala tse ka nchafatsoang
– Mehlodi ya thepa e tala bakeng sa di-biopolymer tsa tlhaho e ka ntjhafatswa, jwalo ka dimela le dikokwana-hloko, ho fapana le dipolasetiki tse tlwaelehileng tse itshetlehileng ka peterole.
3. Ho lumellana ha lintho tse phelang
– Li-biopolymer tse ngata tsa tlhaho li bolokehile ho sebelisoa lits'ebetsong tsa bongaka hobane ha li bake lik'hemik'hale tse chefo 'meleng.
4. Litšobotsi tse fapaneng
– Ho latela mofuta le mokhoa oa tlhahiso, li-biopolymer tsa tlhaho li ka ba le mefuta e fapaneng ea thepa ea mechini e ka etsoang ho latela litlhoko tse itseng.
5. Fokotsa Khabone e Fokotsang
– Ts'ebetso ea tlhahiso ea biopolymer hangata e hloka matla a fokolang ho feta tlhahiso ea polymer e thehiloeng mafura a khale, ka hona e fokotsa tšitiso ea khabone.
Liphephetso le Bokamoso
Leha di-biopolymer tsa tlhaho di na le melemo e mengata, diphephetso tse mmalwa di ntse di le teng. Phephetso e kgolo ke ditjeo tsa tsona tsa tlhahiso tse atisang ho ba hodimo ha di bapiswa le dipolasetiki tse tlwaelehileng. Ditheknoloji tse tswetseng pele haholo, mekgwa ya tlhahiso, le moruo wa sekala di lebelletswe ho fokotsa ditjeo tsena nakong e tlang.
Ho feta moo, ho na le diphephetso mabapi le tshebetso ya di-biopolymer tsa tlhaho, tseo ka dinako tse ding di salang morao ho dipolasetiki tsa setso. Leha ho le jwalo, dipatlisiso le ntshetsopele di ntse di tswela pele ho rarolla mefokolo ena le ho etsa hore di-biopolymer tsa tlhaho di qothisane lehlokoa le ho feta.
Qetello
Li-biopolymer tsa tlhaho li fana ka tharollo e tšepisang mathateng a tikoloho a bakoang ke tšebeliso ea polasetiki ea setso. Ka melemo e kang botsoalle ba tikoloho, ho lumellana ha lintho tse phelang, le mefuta e mengata ea lits'ebetso, li-biopolymer tsa tlhaho li na le monyetla oa ho ba lisebelisoa tsa bohlokoa tsa bokamoso. Leha liphephetso li ntse li le teng, boqapi bo tsoelang pele le nts'etsopele ea theknoloji li fana ka tšepo ea hore li-biopolymer tsa tlhaho li tla qothisana lehlokoa haholoanyane 'me li fokotse tšusumetso ea tsona e mpe tikolohong. Bokhoni bo boholo ba li-biopolymer tsa tlhaho ha bo felle feela menyetla bakeng sa indasteri empa hape bo matlafatsa tšepo bakeng sa botsitso ba tikoloho ea polanete ea rona.
