Tam sim no, cov khoom siv tseem ceeb ntawm polylactic acid yog cov ntaub ntawv ntim khoom, suav txog ntau dua 65% ntawm tag nrho cov kev siv; ua raws li cov ntawv thov xws li cov khoom siv ua noj ua haus, cov fibers / cov ntaub tsis-woven, thiab cov ntaub ntawv luam tawm 3D. Tebchaws Europe thiab North America yog cov lag luam loj tshaj plaws rau PLA, thaum Asia Pacific yuav yog ib qho ntawm cov lag luam loj hlob sai tshaj plaws hauv ntiaj teb vim tias qhov kev thov rau PLA txuas ntxiv loj hlob hauv cov tebchaws xws li Tuam Tshoj, Nyiv, Kaus Lim Qab Teb, Is Nrias teb thiab Thaib teb.
Los ntawm qhov kev xav ntawm hom kev siv, vim nws cov khoom siv kho tshuab thiab lub cev zoo, polylactic acid yog qhov tsim nyog rau extrusion molding, txhaj tshuaj molding, extrusion tshuab molding, spinning, foaming thiab lwm yam txheej txheem ua yas loj, thiab tuaj yeem ua rau hauv zaj duab xis thiab ntawv. , fiber, hlau, hmoov thiab lwm yam. Yog li ntawd, nrog rau lub sijhawm dhau mus, cov xwm txheej thov ntawm polylactic acid hauv ntiaj teb txuas ntxiv nthuav dav, thiab nws tau siv dav hauv cov khoom noj khoom haus sib cuag thiab cov khoom siv rooj tog, cov khoom ntim hnab zaj duab xis, shale gas mining, fibers, ntaub, 3D luam ntawv cov ntaub ntawv thiab lwm yam khoom Nws tab tom tshawb nrhiav ntxiv nws cov peev xwm siv hauv cov teb ntawm tshuaj, khoom siv tsheb, kev ua liaj ua teb, kev cog ntoo thiab kev tiv thaiv ib puag ncig.
Hauv daim ntawv thov hauv kev lag luam tsheb, tam sim no, qee cov ntaub ntawv polymer ntxiv rau PLA los ua cov khoom sib xyaw kom txhim kho qhov kub tsis kam, kev yooj ywm thiab kev cuam tshuam ntawm PLA, yog li nthuav nws daim ntawv thov hauv kev lag luam tsheb.
Cov xwm txheej ntawm cov ntawv thov txawv teb chaws
Kev siv cov polylactic acid hauv tsheb txawv teb chaws pib thaum ntxov, thiab cov thev naus laus zis tau paub tab heev, thiab kev siv cov polylactic acid hloov kho tau zoo heev. Qee lub npe tsheb txawv teb chaws uas peb paub siv cov polylactic acid hloov kho.
Mazda Motor Corporation, koom tes nrog Teijin Corporation thiab Teijin Fiber Corporation, tau tsim lub ntiaj teb thawj bio-fabric ua los ntawm 100% polylactic acid, uas yog siv rau qhov zoo thiab kev ruaj khov ntawm lub rooj zaum hauv lub tsheb sab hauv. nruab nrab; Nyiv Mitsubishi Nylon Company tsim thiab muag ib hom PLA ua cov khoom siv tseem ceeb rau cov ntaub pua plag hauv pem teb tsheb. Cov khoom no tau siv hauv Toyota lub tsheb hybrid tiam thib peb hauv xyoo 2009.
Cov khoom siv polylactic acid fiber uas tsis ua rau ib puag ncig puas tsuaj uas tsim los ntawm Nyiv Pooj Toray Industries Co., Ltd. tau siv los ua lub cev thiab hauv pem teb ntawm Toyota Motor Corporation lub tsheb hybrid sedan HS 250 h. Cov khoom siv no kuj siv tau rau cov qab nthab sab hauv thiab cov khoom siv upholstery ntawm qhov rooj.
Cov qauv Raum ntawm Toyota hauv Nyiv siv cov khoom siv kenaf fiber/PLA los ua lub hau npog log tsheb, thiab cov khoom siv hloov kho polypropylene (PP)/PLA los ua cov vaj huam sib luag qhov rooj tsheb thiab cov vaj huam sib luag sab.
Lub Tuam Txhab German Röchling thiab Lub Tuam Txhab Corbion tau sib koom ua ke tsim cov khoom sib xyaw ua ke ntawm PLA thiab iav fiber lossis ntoo fiber, uas yog siv rau hauv cov khoom siv sab hauv tsheb thiab cov khoom siv ua haujlwm.
Lub Tuam Txhab American RTP tau tsim cov khoom siv fiber ntau ua los ntawm iav, uas siv rau hauv cov ntaub thaiv cua hauv tsheb, cov ntaub thaiv hnub ci, cov khoom siv bumpers, cov ntaub thaiv sab thiab lwm yam khoom. Cov ntaub thaiv cua EU, cov ntaub thaiv hnub ci, cov khoom siv bumpers me, cov ntaub thaiv sab thiab lwm yam khoom.
Qhov project EU ECOplast tau tsim cov yas bio-based ua los ntawm PLA thiab nanoclay, uas yog siv tshwj xeeb hauv kev tsim cov khoom siv tsheb.
Cov xwm txheej ntawm daim ntawv thov hauv tebchaws
Kev tshawb fawb txog kev siv PLA hauv tsev hauv kev lag luam tsheb tseem lig heev, tab sis nrog kev txhim kho ntawm kev paub txog kev tiv thaiv ib puag ncig hauv tsev, cov tuam txhab tsheb hauv tsev thiab cov kws tshawb fawb tau pib nce kev tshawb fawb thiab kev txhim kho thiab kev siv PLA hloov kho rau tsheb, thiab kev siv PLA hauv tsheb tau nrawm heev. Kev txhim kho thiab kev txhawb nqa. Tam sim no, PLA hauv tsev feem ntau yog siv rau hauv cov khoom sab hauv tsheb thiab cov khoom.
Lvcheng Biomaterials Technology Co., Ltd. tau tsim cov khoom siv PLA composite uas muaj zog thiab ruaj khov, uas tau siv rau hauv cov grilles cua nkag hauv tsheb, cov thav duab qhov rai peb ceg thiab lwm yam khoom.
Kumho Sunli tau ua tiav tsim cov polycarbonate PC/PLA, uas muaj cov khoom siv kho tshuab zoo thiab lwj tau thiab rov ua dua tshiab, thiab siv rau hauv cov khoom siv sab hauv tsheb.
Tongji University thiab SAIC kuj tau koom tes tsim cov khoom siv polylactic acid/natural fiber composite, uas yuav siv ua cov khoom siv sab hauv rau SAIC cov tsheb hom.
Kev tshawb fawb hauv tsev txog kev hloov kho PLA yuav raug nce ntxiv, thiab yav tom ntej yuav tsom mus rau kev tsim cov tshuaj polylactic acid nrog lub neej ntev thiab kev ua tau zoo uas ua tau raws li qhov yuav tsum tau siv. Nrog rau kev txhim kho thiab kev nce qib ntawm kev siv tshuab hloov kho, daim ntawv thov ntawm PLA hauv tsev hauv kev lag luam tsheb yuav dav dua.
