Pakalipano, gawo lalikulu la mowa wa polylactic acid ndi zipangizo zonyamula katundu, zomwe zimaposa 65% ya mowa wonse; kutsatiridwa ndi ntchito monga ziwiya zodyera, ulusi/nsalu zosalukidwa, ndi zida zosindikizira za 3D. Europe ndi North America ndi misika yayikulu kwambiri ya PLA, pomwe Asia Pacific idzakhala imodzi mwamisika yomwe ikukula mwachangu padziko lonse lapansi pomwe kufunikira kwa PLA kukukulirakulira m'maiko monga China, Japan, South Korea, India ndi Thailand.
Malinga ndi mawonekedwe a ntchito, chifukwa cha mawonekedwe ake abwino amakina ndi thupi, asidi polylactic ndi oyenera akamaumba extrusion, jekeseni akamaumba, extrusion kuwomba akamaumba, kupota, thovu ndi zina zikuluzikulu pulasitiki processing njira, ndipo akhoza kupanga mafilimu ndi mapepala. , CHIKWANGWANI, waya, ufa ndi mitundu ina. Chifukwa chake, m'kupita kwa nthawi, mawonekedwe a ntchito ya polylactic acid padziko lapansi akupitilizabe kukula, ndipo akhala akugwiritsidwa ntchito kwambiri popaka ma CD ndi ma tableware, zinthu zonyamula thumba la filimu, migodi ya gasi wa shale, ulusi, nsalu, kusindikiza kwa 3D. Zida ndi zinthu zina Ikuwunikanso momwe angagwiritsire ntchito pazamankhwala, zida zamagalimoto, ulimi, nkhalango ndi kuteteza chilengedwe.
Pakugwiritsa ntchito m'munda wamagalimoto, pakadali pano, zida zina za polima zimawonjezedwa ku PLA kuti apange zophatikiza kuti zithandizire kukana kutentha, kusinthasintha komanso kukana kwamphamvu kwa PLA, potero kukulitsa kuchuluka kwake pamsika wamagalimoto. .
Mkhalidwe wa ntchito zakunja
Kugwiritsa ntchito asidi wa polylactic m'magalimoto akunja kunayamba koyambirira, ndipo ukadaulo ndiwokhwima, komanso kugwiritsa ntchito asidi osinthidwa a polylactic ndikwapamwamba kwambiri. Mitundu ina yamagalimoto akunja omwe timawadziwa amagwiritsa ntchito asidi osinthidwa a polylactic.

Kampani yaku Germany Röchling ndi Corbion Company apanga limodzi zinthu zophatikizika za PLA ndi ulusi wagalasi kapena ulusi wamatabwa, womwe umagwiritsidwa ntchito m'zigawo zamkati zamagalimoto ndi zida zogwirira ntchito.
Kampani ya American RTP yapanga zinthu zopangidwa ndi magalasi, zomwe zimagwiritsidwa ntchito popangira mpweya wamagalimoto, mithunzi ya dzuwa, mabampa othandizira, alonda am'mbali ndi mbali zina. EU air shrouds, hoods dzuwa, sub-bumpers, alonda mbali ndi mbali zina.
Pulojekiti ya EU ECOplast yapanga pulasitiki yopangidwa kuchokera ku PLA ndi nanoclay, yomwe imagwiritsidwa ntchito mwapadera popanga zida zamagalimoto.
Ntchito yakunyumba
The ntchito kafukufuku wa PLA zoweta mu makampani magalimoto ndi mochedwa, koma ndi kusintha kwa kuzindikira zoweta zachilengedwe chitetezo, makampani zoweta galimoto ndi ofufuza ayamba kuonjezera kafukufuku ndi chitukuko ndi kugwiritsa ntchito kusinthidwa PLA kwa magalimoto, ndi kugwiritsa ntchito PLA. m'galimoto zakhala zofulumira. chitukuko ndi kukwezedwa. Pakali pano, PLA zoweta zimagwiritsa ntchito mbali magalimoto mkati ndi mbali.
Lvcheng Biomaterials Technology Co., Ltd. yakhazikitsa zida zamphamvu komanso zolimba kwambiri za PLA, zomwe zakhala zikugwiritsidwa ntchito pamagalasi opangira mpweya wamagalimoto, mafelemu am'mawindo atatu ndi mbali zina.
Kumho Sunli yapanga bwino polycarbonate PC/PLA, yomwe ili ndi zida zabwino zamakina ndipo imatha kuwonongeka komanso kubwezeredwa, ndipo imagwiritsidwa ntchito m'zigawo zamkati zamagalimoto.
Tongji University ndi SAIC apanganso mogwirizana polylactic acid/natural fiber composite, zomwe zidzagwiritsidwe ntchito ngati zida zamkati zamagalimoto amtundu wa SAIC.
Kafukufuku wapakhomo wokhudza kusintha kwa PLA adzawonjezeka, ndipo tsogolo labwino lidzakhala pa chitukuko cha mankhwala a polylactic acid okhala ndi moyo wautali wautumiki ndi ntchito zomwe zimakwaniritsa zofunikira zogwiritsira ntchito. Ndi chitukuko ndi kupita patsogolo kwaukadaulo wosinthika, kugwiritsa ntchito PLA yapanyumba m'munda wamagalimoto kudzakhala kokulirapo.
