I-Polylactic acid, eyaziwa ngokuba yi-polylactide, yeyosapho lwe-polyester.I-Polylactic acid (PLA) yipolymer eyenziwe nge-lactic acid njengeyona mathiriyeli ekrwada.Izinto eziluhlaza zininzi kwaye zinokuphinda zihlaziywe.Inkqubo yokuvelisa i-polylactic acid ayingcolisi, kwaye imveliso inokuthi i-biodegradable, iqonda ukujikeleza kwendalo, ngoko yinto efanelekileyo yepolymer eluhlaza.I-Polylactic acid (i-PLA) luhlobo olutsha lwezinto eziphilayo ezinokubola.Yenziwe kwizinto zesitatshi ezikhutshwe kwimithombo yezityalo ezivuselelekayo (ezifana nombona) ngokuvundiswa, kwaye emva koko ziguqulelwe kwi-polylactic acid ngokusebenzisa i-polymer synthesis.
Iasidi yePolylactic ilungele ukubumba ukuvuthela, ukubumba inaliti kunye nezinye iindlela zokulungisa.Kulula ukusetyenzwa kwaye isetyenziswe ngokubanzi.Ingasetyenziselwa ukucubungula izitya zokutya ezahlukeneyo, ukutya okupakishiweyo, iibhokisi zokutya okukhawulezayo kwesidlo sasemini, amalaphu angalukwanga, amalaphu emizi-mveliso kunye nabahlali ukusuka kushishino ukuya kusetyenziso lwabantu.Kwaye ke inokucutshungulwa ibe ngamalaphu ezolimo, amalaphu okhathalelo lwempilo, iiduster, iimveliso zococeko, amalaphu angaphandle anganyangekiyo e-UV, amalaphu entente, iimethi zomgangatho, njl njl. Ithemba lemarike lithembisa kakhulu.Inokubonwa ukuba iipropathi zayo zoomatshini nezomzimba zilungile.
Zeziphi iingenelo ze-PLA yemathiriyeli ekrwada?
1. Ine-biodegradability elungileyo.Emva kokusetyenziswa, inokutshatyalaliswa ngokupheleleyo ngama-microorganisms kwindalo phantsi kweemeko ezithile, kwaye ekugqibeleni ivelise i-carbon dioxide kunye namanzi, ngaphandle kokungcolisa indalo.Indlela yonyango yeeplastiki eziqhelekileyo isavutha kwaye itshiswa, nto leyo ebangela ukuba kukhutshwe igesi enkulu ye-greenhouse emoyeni, ngelixa iiplastiki ze-polylactic acid (PLA) zingcwatyelwa emhlabeni ukuze zithotywe, kwaye i-carbon dioxide eveliswa ngokuthe ngqo ingena ngaphakathi. umhlaba wezinto eziphilayo okanye ufunnwe zizityalo, ezingayi kukhutshwa emoyeni kwaye ayiyi kudala i-greenhouse effect.
2. Iimpawu ezilungileyo zoomatshini kunye nezomzimba.Kulula ukusetyenzwa, isetyenziswa ngokubanzi, kwaye inethemba elihle kakhulu lemarike.
3. Ukuhambelana kakuhle kunye nokuthotywa.Ikwasetyenziswa ngokubanzi kwicandelo lezonyango.
4. I-Polylactic acid (i-PLA) ifana neeplastiki ze-petrochemical synthetic kwiipropati zomzimba ezisisiseko kwaye zingasetyenziselwa ngokubanzi ukwenza iimveliso ezahlukeneyo zesicelo.I-Poly (i-lactic acid) (i-PLA) nayo inobuhle obuhle kunye nokungafihli, okulinganayo nefilimu eyenziwe nge-polystyrene kwaye ayinakubonelelwa ngezinye iimveliso ze-biodegradable.
5. I-Polylactic acid (i-PLA) inamandla amakhulu kunye ne-ductility, kwaye inokuveliswa ngeendlela ezahlukeneyo zokucubungula eziqhelekileyo.I-Poly lactic acid (PLA) inokwenziwa kwiimveliso ezahlukeneyo ngokweemfuno zamashishini ahlukeneyo.
6. Ifilimu yePoly (lactic acid) (PLA) inomoya omhle wokungena komoya, ukunyanzeliswa kwe-oksijini kunye ne-carbon dioxide permeability, kwaye ineempawu zokuzihlukanisa nevumba.Iintsholongwane kunye nokubunjwa kulula ukunamathela kumphezulu weeplastiki ze-biodegradable, ngoko kukho ukuthandabuza malunga nokhuseleko kunye nococeko.Nangona kunjalo, i-polylactic acid kuphela kweplastiki enokubola kunye neempawu ezibalaseleyo ze-antibacterial kunye ne-anti mold.
7. Xa i-PLA itshiswa, ixabiso layo lobushushu lokutsha liyafana nelo lephepha, elisisiqingatha seplastiki yesintu (efana ne-polyethylene).Ukongeza, ayinakuze ikhuphe i-nitrogen compounds, i-sulfide kunye nezinye iigesi ezinetyhefu.
