Intshayelelo
Ngexesha apho iinkxalabo zokusingqongileyo zithatha indawo ephambili, ukufuna ezinye iindlela ezilungele i-eco-friendly kwiiplastiki zemveli kukhokelele ekuveleni kwezinto ezintsha ezifana nePolylactic Acid (PLA). Kule posi yebhlog, siza kungena kwindawo ye-PLA, sihlolisise imvelaphi yayo, iipropati, izicelo, kunye nefuthe lokusingqongileyo. Injongo yethu kukukhanyisa indlela iPLA ebumba ngayo ikamva leplastiki.
Yintoni iPolylactic Acid (PLA)?
I-Polylactic Acid, okanye i-PLA, i-biodegradable kunye ne-bioactive thermoplastic ephuma kwimithombo ehlaziyiweyo efana ne-corn starch okanye iswekile. Yenziwa ngepolymerization ye-lactic acid kwaye igqamile kwiiplastiki zesiqhelo ngenxa yokubola kwayo okukhethekileyo kunye nokuvundisa.
Iipropati zePLA
I-PLA ineempawu ezininzi eziphambili ezenza ukuba ibe yenye enyanzelwayo kwiiplastiki zemveli:
- Ukungafihli kunye nenkangeleko: I-PLA yaziwa ngokungafihlisiyo, iyenza ilungele izicelo apho i-aesthetics ibaluleke kakhulu.
- Amandla kunye nokuqina: Ibonisa amandla amahle kunye nokuqina, ikhuphisana nezinye iiplastiki eziqhelekileyo ezifana ne-PET.
- Ukumelana nobushushu: Ngelixa i-PLA inokumelana namaqondo obushushu aphakathi, inokonakala kumaqondo obushushu aphezulu xa ithelekiswa neeplastiki ezinje Iipolypropylene (PP).
- Iinkcazelo Ngeempawu Zomqobo: I-PLA inokubonelela ngeempawu ezifanelekileyo zomqobo kwizicelo ezithile, nangona inokufuna uhlengahlengiso kwiimfuno ezinzima ngakumbi.
Inkqubo yokuVelisa
Ukuveliswa kwePLA kuqala ngokutsalwa kweswekile evundileyo kwizityalo ezinjengombona okanye ummoba. Ezi swekile ke ziguqulwa zibe yi-lactic acid ngenkqubo yokuvundiswa. Emva koko, i-PLA i-polymerization iyenzeka, ekhokelela ekubunjweni kweepellets ze-resin ezisetyenziswa kwizicelo ezahlukeneyo. Enye inzuzo ephawulekayo yokuveliswa kwe-PLA kukunciphisa i-carbon footprint, njengoko ixhomekeke kwimithombo ehlaziyiweyo kwaye idla amandla amancinci kuneeplastiki zepetroleum.
Usetyenziso lwe-PLA
Ukuguquguquka kwe-PLA kukhokelele ekwamkelweni kwayo kumashishini ahlukeneyo kunye nezicelo:
- Ukupakishwa kokutya: I-PLA isoloko isetyenziselwa izikhongozeli zokutya, i-cutlery, kunye neefilimu zokutya ngenxa yokubola kwayo kunye nendalo engeyiyo ityhefu.
- Ushicilelo lwe-3D: Ubulula bayo bokuprinta kunye nokonakala kwezinto eziphilayo kwenza i-PLA ibe yintandokazi kuluntu loshicilelo lwe-3D ngokwenza iiprototypes, iithoyi, kunye neziqwenga zobugcisa.
- Umqhaphu kunye nesinxibo: Amalaphu asekwe kwi-PLA avela njengezinye iindlela ezizinzileyo kwishishini lefashoni, ezibonelela ngezibonelelo ezinjengokuphefumla kunye nokususa ukufuma.
- Izixhobo zonyango: I-PLA ye-biocompatibility yenza ukuba ifaneleke kwizicelo zonyango ezifana ne-sutures kunye neenkqubo zokuhanjiswa kweziyobisi.
Impembelelo yokusingqongileyo
I-PLA ibonelela ngeenzuzo ezibalulekileyo zokusingqongileyo:
- UkuNcitshiswa kokuKhutshwa kweGesi ye-Greenhouse: Imveliso ye-PLA ivelisa ukukhutshwa kwegesi encinci ye-greenhouse xa kuthelekiswa neeplastiki ezisekelwe kwipetroleum.
- Ukuguquguquka kweBioodegradability kunye nokuThobeka: I-PLA inokuphucula i-biodegrade phantsi kweemeko ezithile, ukunciphisa inkunkuma yeplastiki kwiindawo zokulahla inkunkuma kunye nolwandle.
- UkuNcitshiswa kweFossil Fuel Ukuxhomekeka: Ukuthembela kwe-PLA kwimithombo ehlaziyekayo kunciphisa ukuxhomekeka kwethu kumafutha efosili.
Kubalulekile ukuqaphela ukuba ukuthotywa kwe-biodegradation okusebenzayo kwe-PLA kufuna iimeko ezithile zokwenziwa komgquba kwimizi-mveliso, ezinokungafumaneki jikelele.
I-PLA vs. IiPlastiki zesiNtu
Ukuqonda ngcono izibonelelo ze-PLA, masiyithelekise neeplastiki zemveli:
| Ipropati | I-PLA | I-PET | PP |
|---|---|---|---|
| I-Biodegradability | Ewe | Hayi | Hayi |
| Ukungafihli | Phezulu | Phezulu | Phantsi |
| Amandla kunye nokuqina | Kulungile | Egqwesileyo | Kulungile |
| Ukumelana nobushushu | Phakathi | Phezulu | Phezulu |
| Umthombo weMveliso | Ukuhlaziywa (Izityalo) | Amafutha eFossil (Petroleum) | Amafutha eFossil (Petroleum) |
| Impembelelo yokusingqongileyo | Unyawo lwekhabhoni esezantsi | Umgangatho ophezulu wekhabhoni | Umgangatho ophezulu wekhabhoni |
Ngelixa i-PLA igqwesa kwi-biodegradability kunye ne-carbon footprint encitshisiweyo, inokuba nemida ekuchaseni ubushushu kwizicelo ezithile.
Amathemba kunye nemingeni yexesha elizayo
Ikamva lePLA linesithembiso kunye nemingeni ngokufanayo. Abaphandi bayaqhubeka nokusebenza ekuphuculeni iimpawu zayo, ngakumbi ukuxhathisa ukushisa, ukwandisa uluhlu lwayo lwezicelo. Impumelelo ye-PLA ikwaxhomekeke kuphuhliso lohlaziyo oluphuculweyo kunye neziseko zokwenziwa komgquba ukuze kwandiswe iinzuzo zayo zokusingqongileyo.
Ukuqukumbela
Ekufuneni ezinye iiplastiki ezizinzileyo, i-Polylactic Acid (PLA) ikhanya njengokukhanya kwethemba. Ngokonakala kwayo kwezinto eziphilayo, ukufumaneka ngokutsha, kunye nokuguquguquka kwezinto ezininzi, i-PLA inikezela ngesisombululo esinyanzelisayo sokunciphisa ungcoliseko lweplastiki kunye nokuxhomekeka kwethu kumafutha efosili. Njengoko siphonononga iindlela zokukhusela iplanethi yethu, i-PLA isebenza njengomzekelo wendlela izinto ezintsha ezinokuvula indlela eya kwikamva elizinzileyo.
