Njengamanje, insimu eyinhloko yokusetshenziswa kwe-polylactic acid yizinto zokupakisha, ezibalelwa ngaphezu kwama-65% wokusetshenziswa okuphelele; kulandelwe izinhlelo zokusebenza ezifana nezitsha zokupheka, imicu/izindwangu ezingalukiwe, kanye nezinto zokunyathelisa ze-3D. IYurophu neNyakatho Melika yizimakethe ezinkulu ze-PLA, kanti i-Asia Pacific izoba enye yezimakethe ezikhula ngokushesha emhlabeni njengoba isidingo se-PLA siqhubeka nokukhula emazweni afana neShayina, iJapan, iSouth Korea, iNdiya kanye neThailand.
Ngokombono wemodi yokusebenzisa, ngenxa yezakhiwo zayo ezinhle zemishini nezomzimba, i-polylactic acid ifanelekela ukubumba i-extrusion, ukubumba ngomjovo, ukubumba i-extrusion blow, ukuphotha, ukwenza i-foam kanye nezinye izinqubo ezinkulu zokucubungula ipulasitiki, futhi ingenziwa amafilimu namashidi. , i-fiber, ucingo, i-powder nezinye izinhlobo. Ngakho-ke, ngokuhamba kwesikhathi, izimo zokusetshenziswa kwe-polylactic acid emhlabeni ziyaqhubeka nokukhula, futhi isetshenziswe kabanzi ekupakisheni nasekuphatheni ukudla okunezinga lokuxhumana, imikhiqizo yokupakisha izikhwama zefilimu, ukumbiwa kwegesi ye-shale, imicu, izindwangu, izinto zokunyathelisa ze-3D kanye neminye imikhiqizo. Iqhubeka nokuhlola amandla ayo okusetshenziswa emikhakheni yezokwelapha, izingxenye zezimoto, ezolimo, amahlathi kanye nokuvikelwa kwemvelo.
Ekusetshenzisweni emkhakheni wezimoto, njengamanje, ezinye izinto ze-polymer zengezwa ku-PLA ukuze kwenziwe izinhlanganisela zokuthuthukisa ukumelana nokushisa, ukuguquguquka kanye nokumelana nomthelela we-PLA, ngaleyo ndlela kwandiswe ububanzi bokusetshenziswa kwayo emakethe yezimoto.
Isimo sezicelo zakwamanye amazwe
Ukusetshenziswa kwe-polylactic acid ezimotweni zakwamanye amazwe kwaqala kusenesikhathi, futhi ubuchwepheshe sebuvuthiwe impela, futhi ukusetshenziswa kwe-modified polylactic acid sekuthuthukile kakhulu. Ezinye izinhlobo zezimoto zakwamanye amazwe esizaziyo zisebenzisa i-modified polylactic acid.
I-Mazda Motor Corporation, ngokubambisana ne-Teijin Corporation kanye ne-Teijin Fiber Corporation, ithuthukise indwangu yokuqala emhlabeni eyenziwe nge-polylactic acid engu-100%, esetshenziswa ezidingweni zekhwalithi nokuqina kwesembozo sesihlalo semoto ngaphakathi kwemoto. I-Mitsubishi Nylon Company yaseJapan yakhiqiza futhi yathengisa uhlobo lwe-PLA njengezinto eziyinhloko zomata bephansi bezimoto. Lo mkhiqizo wasetshenziswa emotweni entsha ye-hybrid yesizukulwane sesithathu seToyota ngo-2009.
Izinto ze-polylactic acid fiber ezinobungani nemvelo ezikhiqizwe yi-Toray Industries Co., Ltd. yaseJapan zasetshenziswa njengesimbozo somzimba nesangaphakathi sephansi kwi-hybrid sedan HS 250 h yeToyota Motor Corporation. Lezi zinto zingasetshenziswa futhi ekufakeni ophahleni lwangaphakathi kanye nezinto zokuhlobisa iminyango.
Imodeli yeToyota yaseJapane iRaum isebenzisa izinto ezihlanganisiwe ze-kenaf fiber/PLA ukwenza isembozo samathayi esingeziwe, kanye nezinto ezilungisiwe ze-polypropylene (PP)/PLA ukwenza amaphaneli eminyango yemoto kanye namaphaneli okuhlobisa eceleni.
Inkampani iGerman Röchling kanye neCorbion Company bahlanganise ndawonye izinto ezihlanganisiwe ze-PLA kanye ne-glass fiber noma i-wood fiber, ezisetshenziswa ezingxenyeni zangaphakathi zezimoto kanye nezingxenye ezisebenzayo.
Inkampani yaseMelika i-RTP ithuthukise imikhiqizo ehlanganisiwe yefayibha yengilazi, esetshenziswa ezimbozweni zomoya zezimoto, ezimbozweni zelanga, ezimbozweni ezisizayo, ezimbozweni ezisemaceleni nakwezinye izingxenye. Izimbozweni zomoya ze-EU, izimbozweni zelanga, ezimbozweni ezisemaceleni, ezimbozweni ezisemaceleni nezinye izingxenye.
Iphrojekthi ye-EU ECOplast ithuthukise ipulasitiki esekelwe ku-bio eyenziwe nge-PLA kanye ne-nanoclay, esetshenziswa ngokukhethekile ekukhiqizweni kwezingxenye zezimoto.
Isimo sesicelo sasekhaya
Ucwaningo lokusetshenziswa kwe-PLA yasekhaya embonini yezimoto seluphuzile, kodwa ngokuthuthuka kokuqwashisa ngokuvikelwa kwemvelo yasekhaya, izinkampani zezimoto zasekhaya kanye nabacwaningi sebeqalile ukwandisa ucwaningo kanye nentuthuko kanye nokusetshenziswa kwe-PLA eguquliwe yezimoto, futhi ukusetshenziswa kwe-PLA ezimotweni kube ngokushesha. Njengamanje, i-PLA yasekhaya isetshenziswa kakhulu ezingxenyeni zangaphakathi zezimoto kanye nezingxenye.
I-Lvcheng Biomaterials Technology Co., Ltd. yethule izinto ezihlanganisiwe ze-PLA ezinamandla aphezulu futhi eziqinile, ezisetshenziswe kuma-grilles okungenisa umoya ezimotweni, ozimele bamafasitela abangonxantathu nakwezinye izingxenye.
I-Kumho Sunli iphumelele ukuthuthukisa i-polycarbonate PC/PLA, enezakhiwo ezinhle zemishini futhi ebola futhi ingasetshenziswa kabusha, futhi isetshenziswa ezingxenyeni zangaphakathi zezimoto.
I-Tongji University kanye ne-SAIC baphinde bathuthukisa ndawonye izinto ezihlanganisiwe ze-polylactic acid/natural fiber, ezizosetshenziswa njengezinto zangaphakathi zezimoto zomkhiqizo we-SAIC.
Ucwaningo lwasekhaya mayelana nokuguqulwa kwe-PLA luzokwandiswa, futhi ukugxila esikhathini esizayo kuzoba ekuthuthukisweni kwamakhemikhali e-polylactic acid anempilo ende yokusebenza kanye nokusebenza okuhlangabezana nezidingo zokusetshenziswa. Ngokuthuthuka kanye nentuthuko yobuchwepheshe bokuguqulwa, ukusetshenziswa kwe-PLA yasekhaya emkhakheni wezimoto kuzoba kukhulu kakhulu.
