Kutshanje, iingxowa zeplastiki ezibolisiweyo zithandwa kakhulu, kwaye amanqanaba ahlukeneyo okuvalwa kweplastiki aqalisiwe kwihlabathi liphela, kwaye njengenye yeentlobo eziphambili zeengxowa zeplastiki ezinokonakala ngokwendalo, iPLA ngokwendalo yenye yezinto eziphambili eziphambili.Masilandele ngokusondeleyo umenzi wengxowa yokupakisha i-TOP PACK ukuqonda iingxowa zeplastiki ezibolisiweyo ze-PLA.
- Yintoni i-PLA kwaye yenziwe ngantoni?
I-PLA yipolymer (i-polylactic acid) eyenziwe ngeeyunithi ezincinci ze-lactic acid.I-lactic acid yi-asidi ephilayo edlala indima ebalulekileyo kubomi bethu bemihla ngemihla.I-yogurt esiqhele ukuyisela okanye nayiphi na into ene-glucose inokuguqulwa ibe yi-lactic acid, kwaye i-lactic acid ye-PLA yezinto ezisetyenziswayo zivela kwingqolowa, eyenziwe kwi-starch ekrwada ekhutshwe kwingqolowa.
Okwangoku, i-PLA yenye yezona zinto zixhaphakileyo ezisetyenziswa kwiingxowa zeplastiki ezibolayo, inophawu olukhethekileyo: I-PLA yenye yezinto ezingenabuthi ezinobuthi, izinto zayo ezikrwada kwindalo.
- Ingaba izinga lokuthotywa kwePLA lixhomekeke kwintoni?
Inkqubo yokuguqulwa kwezinto eziphilayo kunye nobude bayo buxhomekeke kakhulu kwindalo esingqongileyo.Umzekelo, ubushushu, ukufuma, kunye ne microbes Ukungcwaba iPLA iiplastiki ezonakalise ngokupheleleyo ezinzulu emhlabeni kunokubangela iimpawu zokubola kwisithuba seenyanga ezintandathu.
Kwaye iingxowa zeplastiki ze-PLA ze-biodegradable zithatha ixesha elide ukuthotywa kwiqondo lokushisa kunye naphantsi koxinzelelo.Kwigumbi eliqhelekileyo, ukuthotywa kweengxowa zeplastiki eziguquguqukayo zePLA kuya kuhlala ixesha elide.Ukukhanya kwelanga akuyi kukhawulezisa i-biodegradation (ngaphandle kobushushu), kunye nokukhanya kwe-UV kuya kubangela kuphela ukuba izinto zilahlekelwe ngumbala wazo kwaye zibe luhlaza, okuyimpembelelo efanayo kunye neeplastiki ezininzi.
Iingenelo zokusebenzisa iingxowa zeplastiki ezibolayo ze-PLA
Kwimbali yoluntu, iingxowa zeplastiki zilula kakhulu kwaye zilungele ukuzisebenzisa, okubangelwa ukuba abantu baye bahlukana kwiingxowa zeplastiki ebomini babo bemihla ngemihla.Ukulungelelaniswa kweengxowa zeplastiki kubangela ukuba abantu balibale ukuba ukuveliswa kokuqala kweengxowa zeplastiki akuyona into elahlayo, edla ngokusetyenziswa kanye kwaye ilahlwe.Kodwa abantu abaninzi abazi ukuba eyona nto iphambili ekrwada yokuveliswa kweengxowa zeplastiki yi-polyethylene, okunzima kakhulu ukuyithoba.Inani elikhulu leeplastiki ezilahliweyo zingcwatywa emhlabeni, eziya kukhokelela kwindawo enkulu yomhlaba ngenxa yokungcwatywa kweengxowa zeplastiki kunye nokuhlala ixesha elide.Olu lungcoliseko olumhlophe.Xa abantu besebenzisa iiplastiki kwiingxowa zeplastiki ezinokubola, le ngxaki iya kusonjululwa.I-PLA yenye yezona zinto zixhaphakileyo zeplastiki ezinokubola kwaye i-polymer eyenziwe nge-lactic acid, eyimveliso engangcolisi kunye ne-biodegradable.Emva kokusetyenziswa, i-PLA inokuxutywa kwaye ihlaziywe kwi-carbon dioxide kunye namanzi kumaqondo okushisa angaphezu kwama-55 ° C okanye ngesenzo se-microorganisms ene-oksijini ukuphumeza umjikelezo wezinto eziphathekayo kwindalo.Xa kuthelekiswa noqobo lweengxowa zeplastiki eziqhelekileyo, iiplastiki ezonakaliswa ngebhayoloji zifuna kuphela iinyanga ezimbalwa ukugqiba ukuthotywa kwexesha.Oku kunciphisa inkcitho yobutyebi bomhlaba ukuya kumlinganiselo omkhulu kwaye ayinayo impembelelo kokusingqongileyo.Ukongeza, iingxowa zeplastiki eziqhelekileyo kwinkqubo yokuvelisa ziya kusebenzisa amafutha efosili, ngelixa iiplastiki ezibolisiweyo ziya kunciphisa phantse isiqingatha samafutha efosili kunawo.Umzekelo, ukuba zonke iimveliso zeplastiki emhlabeni bezinokutshintshwa ziingxowa zeplastiki ezinokubola ngonyaka, oko bekuya konga phantse i-1.3 yeebhiliyoni zeebhareli zamafutha efosili ngonyaka, nto leyo ephantse ibe yinxalenye yokusetyenziswa kwe-fuel yehlabathi.Ukungalungi kwe-PLA ziimeko ezinzima zokuthotywa kwexabiso.Nangona kunjalo, ngenxa yexabiso eliphantsi ngokwentelekiso ye-PLA kwizinto zeplastiki ezinokubola, ukusetyenziswa kwe-PLA kuphambili.
