Parizvino, nzvimbo huru inoshandiswa ye polylactic acid ndeyezvinhu zvekurongedza, zvinosvika 65% yezvese zvinoshandiswa; zvichiteverwa nezvishandiso zvakaita semidziyo yekubikira, machira asina kurukwa, uye zvinhu zvekudhinda zve3D. Europe neNorth America ndiwo misika mikuru yePLA, nepo Asia Pacific ichave imwe yemisika iri kukura nekukurumidza pasi rose sezvo kudiwa kwePLA kuri kuramba kuchikura munyika dzakadai seChina, Japan, South Korea, India neThailand.
Kubva pamaonero ekushandisa, nekuda kwehunhu hwayo hwakanaka hwemakanika uye hwepanyama, polylactic acid yakakodzera kuumbwa kweextrusion, kuumbwa kwejekiseni, kuumbwa kweblow extrusion, kutenderera, kupupuma uye mamwe maitiro makuru ekugadzira mapurasitiki, uye inogona kugadzirwa kuita mafirimu nemapepa, fiber, waya, upfu nedzimwe mhando. Nokudaro, nekufamba kwenguva, mamiriro ekushandiswa kwepolylactic acid pasi rose ari kuramba achikura, uye yave ichishandiswa zvakanyanya mukugadzira chikafu nemidziyo yekudya, zvigadzirwa zvekurongedza mabhegi efirimu, kuchera shale gas, fibers, machira, zvinhu zvekudhinda zve3D nezvimwe zvigadzirwa. Iri kuongorora zvakare kugona kwayo kushandiswa muminda yemishonga, zvikamu zvemotokari, kurima, masango nekuchengetedzwa kwezvakatipoteredza.
Mukushandiswa mumunda wemotokari, pari zvino, zvimwe zvinhu zvepolymer zvinowedzerwa kuPLA kuti zvigadzire zvinhu zvinosanganisa kupisa, kuchinjika uye kuramba kupisa kwePLA, nokudaro zvichiwedzera mukana wekushandiswa kwayo mumusika wemotokari.
Mamiriro ezvikumbiro zvekunze kwenyika
Kushandiswa kwepolylactic acid mumotokari dziri kunze kwenyika kwakatanga kare, uye tekinoroji yacho yakura, uye kushandiswa kwemodified polylactic acid kwafambira mberi. Mamwe marudzi emotokari dzekunze atinoziva anoshandisa modified polylactic acid.
Mazda Motor Corporation, pamwe chete neTeijin Corporation neTeijin Fiber Corporation, yakagadzira jira rekutanga pasi rose rakagadzirwa ne100% polylactic acid, iro rinoshandiswa pamhando yepamusoro uye kugara kwenguva refu kwechigaro chemotokari mukati memotokari. Kambani yeMitsubishi Nylon yekuJapan yakagadzira nekutengesa rudzi rwePLA sechinhu chikuru chekugadzira mat pasi pemotokari. Chigadzirwa ichi chakashandiswa mumotokari itsva yeToyota yechizvarwa chechitatu muna 2009.
Motokari yemhando yepolylactic acid fiber inochengetedza nharaunda yakagadzirwa neToray Industries Co., Ltd. yekuJapan yakashandiswa sechifukidziro chemuviri nemukati meimba paToyota Motor Corporation's hybrid sedan HS 250 h. Motokari iyi inogona kushandiswawo padenga remukati uye pakugadzirisa magonhi.
Mota yeToyota yeJapan inonzi Raum inoshandisa zvinhu zvakagadzirwa nekenaf fiber/PLA composite kugadzira chifukidziro chemavhiri emota, uye zvinhu zvakagadzirwa nepolypropylene (PP)/PLA zvakagadziriswa kugadzira mapaneru emasuo emota uye mapaneru emativi.
Kambani yeGerman Röchling neCorbion Company vakabatana kugadzira zvinhu zvakasanganiswa zvePLA negirazi fiber kana huni fiber, izvo zvinoshandiswa muzvikamu zvemukati memotokari uye zvikamu zvinoshanda.
Kambani yeAmerican RTP yakagadzira zvigadzirwa zvegirazi zvinosanganisa fiber, zvinoshandiswa muzvifukidziro zvemhepo zvemota, mashadow ezuva, mabumper ekubatsira, maguard emativi nezvimwe zvikamu. Zvifukidziro zvemhepo zveEU, masun hood, ma sub-bumper, maguard emativi nezvimwe zvikamu.
Chirongwa cheEU ECOplast chakagadzira purasitiki yakagadzirwa nePLA ne nanoclay, iyo inoshandiswa zvakanyanya mukugadzira zvikamu zvemota.
Mamiriro ekunyorera basa repamba
Kutsvagurudza mashandisirwo ePLA yemuno muindasitiri yemotokari kwanonoka, asi nekuvandudzika kweruzivo rwekuchengetedzwa kwezvakatipoteredza mudzimba, makambani emotokari dzemuno nevaongorori vakatanga kuwedzera kutsvagurudza nekugadzira nekushandisa PLA yakagadziriswa pamotokari, uye kushandiswa kwePLA mumotokari kwave kuri kukurumidza. Parizvino, PLA yemuno inonyanya kushandiswa muzvikamu zvemukati memotokari nezvikamu.
Lvcheng Biomaterials Technology Co., Ltd. yatanga zvinhu zvine simba guru uye zvakasimba zvePLA, izvo zvave zvichishandiswa mumagrilles emota anopinda mweya, mafuremu emahwindo ane mativi matatu nezvimwe zvikamu.
Kumho Sunli yakabudirira kugadzira polycarbonate PC/PLA, ine hunhu hwakanaka hwemakanika uye inogona kuora uye inogona kushandiswazve, uye inoshandiswa muzvikamu zvemukati memotokari.
Yunivhesiti yeTongji neSAIC vakagadzirawo pamwe chete zvinhu zvakagadzirwa nepolylactic acid/natural fiber, izvo zvichashandiswa sezvinhu zvemukati zvemota dzeSAIC.
Ongororo dzemuno pamusoro pekushandurwa kwePLA dzichawedzerwa, uye mune ramangwana kutarisisa kuchave pakugadzirwa kwemakemikari epolylactic acid ane hupenyu hurefu hwebasa uye mashandiro anoenderana nezvinodiwa zvekushandiswa. Nekuvandudzwa uye kufambira mberi kwetekinoroji yekushandurwa, kushandiswa kwePLA yemuno mumunda wemotokari kuchave kwakawanda.
