Okwangoku, intsimi esetyenziswa kakhulu ye-polylactic acid zizinto zokupakisha, ezibalelwa ngaphezulu kwe-65% yezinto ezisetyenziswayo iyonke; kulandele izicelo ezifana nezixhobo zokupheka, iifayibha/amalaphu angalukwanga, kunye nezixhobo zokuprinta ze-3D. IYurophu kunye neMntla Melika zezona marike zinkulu ze-PLA, ngelixa i-Asia Pacific iya kuba yenye yeemarike ezikhula ngokukhawuleza kwihlabathi njengoko imfuno ye-PLA iqhubeka nokukhula kumazwe afana neTshayina, iJapan, iSouth Korea, iIndiya kunye neThailand.
Ngokwembono yendlela yokusebenzisa, ngenxa yeempawu zayo ezilungileyo zoomatshini nezomzimba, i-polylactic acid ifanelekile kwi-extrusion molding, i-injection molding, i-extrusion blow molding, i-spinning, i-foam kunye nezinye iinkqubo eziphambili zokucubungula iplastiki, kwaye inokwenziwa ibe ziifilimu kunye namaphepha. , i-fiber, i-wire, i-powder kunye nezinye iindlela. Ke ngoko, ngokuhamba kwexesha, iimeko zokusetyenziswa kwe-polylactic acid kwihlabathi ziyaqhubeka nokukhula, kwaye isetyenziswa kakhulu kwi-food contact grade packaging kunye ne-tableware, iimveliso zokupakisha iibhegi zefilimu, ukumbiwa kwegesi ye-shale, iifayibha, amalaphu, izixhobo zokushicilela ze-3D kunye nezinye iimveliso. Iqhubeka nokuhlola amandla ayo okusetyenziswa kwicandelo lezonyango, iinxalenye zeemoto, ezolimo, amahlathi kunye nokukhuselwa kwendalo.
Kwisicelo kwicandelo leemoto, okwangoku, ezinye izixhobo zepolymer zongezwa kwi-PLA ukwenza ii-composites ukuphucula ukumelana nobushushu, ukuguquguquka kunye nokumelana nempembelelo ye-PLA, ngaloo ndlela yandisa ububanzi besicelo sayo kwimarike yeemoto.
Imeko yezicelo zangaphandle
Ukusetyenziswa kwe-polylactic acid kwiimoto zaphesheya kwaqala kwangethuba, kwaye ubuchwepheshe sele bukhulile, kwaye ukusetyenziswa kwe-modified polylactic acid kuphucukile. Ezinye iimpawu zeemoto zangaphandle esizaziyo zisebenzisa i-modified polylactic acid.
I-Mazda Motor Corporation, ngokubambisana ne-Teijin Corporation kunye ne-Teijin Fiber Corporation, iphuhlise ilaphu lokuqala le-bio-lab elenziwe nge-100% polylactic acid, elisetyenziswa kwiimfuno zomgangatho kunye nokuqina kwesigqubuthelo sesihlalo semoto ngaphakathi kwemoto. I-Mitsubishi Nylon Company yaseJapan ivelise kwaye ithengise uhlobo lwe-PLA njengezinto eziphambili zeemathi zomgangatho weemoto. Le mveliso yasetyenziswa kwimoto entsha yesizukulwana sesithathu seToyota ngo-2009.
Izinto zefayibha ze-polylactic acid ezinobuhlobo nokusingqongileyo ezenziwe yiToray Industries Co., Ltd. yaseJapan zasetyenziswa njengesigqubuthelo somzimba kunye nomgangatho wangaphakathi kwiToyota Motor Corporation's hybrid sedan HS 250 h. Ezi zinto zingasetyenziselwa neesilingi zangaphakathi kunye nezinto zokuhlobisa iingcango.
Imodeli yeToyota yaseJapan iRaum isebenzisa izinto ezidityanisiweyo ze-kenaf fiber/PLA ukwenza isigqubuthelo samatayara aseleyo, kunye nezinto ezilungisiweyo ze-polypropylene (PP)/PLA ukwenza iiphaneli zocango lwemoto kunye neephaneli zokuhlobisa ecaleni.
Inkampani yaseJamani iRöchling kunye neNkampani iCorbion zidibene ngokuphuhlisa izinto ezidityanisiweyo zePLA kunye nefayibha yeglasi okanye ifayibha yomthi, esetyenziswa kwiindawo zangaphakathi zeemoto kunye nezinto ezisebenzayo.
Inkampani yaseMelika i-RTP iphuhlise iimveliso zeglasi ezidityanisiweyo ezinefayibha, ezisetyenziswa kwii-air shrouds zeemoto, kwii-sunshades, kwii-assistive bumpers, kwii-side guards nakwezinye iindawo. Ii-air shrouds ze-EU, ii-sun hoods, ii-sub-bumpers, kwii-side guards nakwezinye iindawo.
Iprojekthi ye-EU ECOplast iphuhlise iplastiki esekwe kwi-bio eyenziwe nge-PLA kunye ne-nanoclay, esetyenziswa ngokukodwa ekuveliseni iinxalenye zeemoto.
Imeko yesicelo sasekhaya
Uphando lwesicelo se-PLA yasekhaya kwishishini leemoto lufike emva kwexesha, kodwa ngokuphuculwa kolwazi lokukhuselwa kwendalo yasekhaya, iinkampani zeemoto zasekhaya kunye nabaphandi baqalise ukwandisa uphando kunye nophuhliso kunye nokusetyenziswa kwe-PLA eguquliweyo kwizithuthi, kwaye ukusetyenziswa kwe-PLA kwiimoto kuye kwaba ngokukhawuleza. Okwangoku, i-PLA yasekhaya isetyenziswa kakhulu kwiindawo zangaphakathi zeemoto kunye neendawo.
I-Lvcheng Biomaterials Technology Co., Ltd. iqalise izixhobo ze-PLA ezidityanisiweyo ezinamandla aphezulu neziqinileyo, ezisetyenziswe kwiigrilles zokungenisa umoya kwiimoto, kwizakhelo zeefestile eziziingxantathu nakwezinye iindawo.
UKumho Sunli uye waphumelela ekuphuhliseni i-polycarbonate PC/PLA, eneempawu ezintle zoomatshini kwaye iyabola kwaye iphinda isetyenziswe, kwaye isetyenziswa kwiindawo zangaphakathi zeemoto.
IYunivesithi yaseTongji kunye ne-SAIC zikwaphuhlise izinto ezidityanisiweyo ze-polylactic acid/natural fiber, eziza kusetyenziswa njengezinto zangaphakathi zezithuthi zeSAIC.
Uphando lwasekhaya malunga nokuguqulwa kwe-PLA luya kwandiswa, kwaye ingqwalasela yexesha elizayo iya kuba kuphuhliso lwee-polylactic acid compounds ezinobomi obude benkonzo kunye nokusebenza okuhlangabezana neemfuno zokusetyenziswa. Ngophuhliso kunye nenkqubela phambili yetekhnoloji yokuguqulwa, ukusetyenziswa kwe-PLA yasekhaya kwicandelo leemoto kuya kuba kubanzi ngakumbi.
