"Kuchepa kwa carbon" wakhala mutu wankhani mu nyengo yatsopano. M'zaka zaposachedwa, chitetezo cha chilengedwe chobiriwira, kuteteza mphamvu, ndi kuchepetsa utsi zalowa pang'onopang'ono m'masomphenya a anthu, ndipo zakhalanso njira yatsopano yolimbikitsira komanso yotchuka kwambiri pakati pa anthu. M'nthawi yobiriwira komanso yotsika kaboni, kugwiritsa ntchito zinthu zomwe zimatha kuwonongeka kumawonedwa ngati chizindikiro chofunikira cha moyo wa carbon wochepa, ndipo kumalemekezedwa ndi kufalitsidwa kwambiri.

Chifukwa cha kufulumira kwa moyo, mabokosi a pulasitiki otayidwa, matumba apulasitiki, timitengo, makapu amadzi ndi zinthu zina zakhala paliponse m'moyo. Mosiyana ndi mapepala, nsalu ndi zipangizo zina, zinthu zapulasitiki zimatayidwa mwachilengedwe ndipo zimakhala zovuta kuti ziwonongeke. Ngakhale kupangitsa moyo wa anthu kukhala wosavuta, kugwiritsa ntchito mopitirira muyeso kungayambitsenso “kuipitsa koyera”. M'nkhaniyi, biodegradable biomaterials atuluka. Zipangizo zowola ndi zinthu zomwe zikungotuluka zomwe zili ndi maubwino ambiri malinga ndi momwe chilengedwe chimagwirira ntchito poyerekeza ndi zinthu zapulasitiki zomwe zimatha kutaya. Zogulitsa zomwe zimapangidwa pogwiritsa ntchito biodegradable biomaterials monga zopangira zili ndi msika waukulu ndipo zimakhala zonyamulira zofunikira pamalingaliro apamwamba a carbon low.

Pali mitundu yambiri ya zinthu zomwe zimatha kuwonongeka, kuphatikizaPCL, PBS, PBAT, PBSA, PHA,PLGA, PLA, ndi zina. Lero tiyang'ana pa PLA yomwe ikubwera yosasinthika.

PLA, amadziwikanso kutipolylactic asidid, Chithunzi cha CAS 26023-30-3ndi wowuma yaiwisi yaiwisi kuti thovu kutulutsa lactic acid, amene kenako n'kukhala asidi polylactic kudzera kaphatikizidwe mankhwala ndipo ali wabwino biodegradability. Mukagwiritsidwa ntchito, zitha kuonongeka kwathunthu ndi tizilombo tating'onoting'ono m'chilengedwe, ndikutulutsa mpweya woipa ndi madzi popanda kuwononga chilengedwe. Chilengedwe ndi chabwino kwambiri, ndipo PLA imadziwika kuti ndi zinthu zachilengedwe zomwe zimakhala ndi zinthu zabwino kwambiri zachilengedwe.

Zida zazikulu za PLA ndi ulusi wongowonjezwdwanso, chimanga ndi zinthu zina zaulimi ndi zam'mbali, ndipo PLA ndi nthambi yofunikira ya zinthu zomwe zimatha kumera. PLA ili ndi mawonekedwe apadera potengera kuuma komanso kuwonekera. Ili ndi biocompatibility yamphamvu, mitundu yosiyanasiyana yogwiritsira ntchito, mphamvu zakuthupi ndi zamakina, ndipo imakwaniritsa zofunikira zosiyanasiyana. Itha kugwiritsidwa ntchito m'njira zosiyanasiyana pakupanga kwakukulu, yokhala ndi antibacterial mlingo wa 99.9%, ndikupangitsa kukhala chinthu chodalirika kwambiri chowonongeka.

Polylactic acid (PLA)ndi chinthu chatsopano chokonda zachilengedwe komanso chobiriwira chomwe chimapangidwa kuchokera ku lactic acid ngati zopangira; M'zaka zaposachedwapa, PLA wakhala ntchito katundu ndi minda monga udzu, tableware, filimu ma CD zipangizo, ulusi, nsalu, 3D kusindikiza zipangizo, etc. PLA alinso ndi mwayi waukulu chitukuko m'minda monga zida zothandizira mankhwala, mbali magalimoto, ulimi. , nkhalango, ndi kuteteza chilengedwe.

PLA yopangidwa ndiUnilong Industryndiye chomaliza mu "tinthu" ta polylactic acid. Kupyolera mwa kusankha okhwima zipangizo apamwamba polylactic asidi zopangira, PLA polylactic asidi pulasitiki ndi PLA polylactic acid CHIKWANGWANI ntchito kupanga wathanzi, khungu wochezeka, apamwamba, ndi amphamvu antibacterial mafuta zochokera m'malo pulasitiki. Zogulitsa zake zazikulu ndi zovala zamasiku ano, nsapato ndi zipewa, zida zapa tebulo, makapu ndi ma ketulo, zolembera, zoseweretsa, nsalu zapakhomo, zovala zotsekera ndi mathalauza, katundu wapakhomo, zopukuta zouma ndi zonyowa, ndi minda ina yokhudzana kwambiri ndi moyo wathu watsiku ndi tsiku.

Kuwonekera kwaPLAZingathandize anthu kuti asakhale kutali ndi kuipitsa koyera, kuchepetsa kuwonongeka kwa pulasitiki, ndikulimbikitsa kukwaniritsidwa kwabwino kwa carbon peak ndi kusalowerera ndale kwa carbon. Cholinga cha Unilong Industry ndi "kuyenda ndi mayendedwe a nthawi, kukhala ndi moyo wokonda zachilengedwe", kulimbikitsa mwamphamvu zinthu zomwe zimatha kuwonongeka, kupangitsa anthu kudya athanzi komanso kukhala ndi moyo wathanzi, kulola kuwonongeka kwachilengedwe kulowa m'mabanja masauzande ambiri, kutsogolera njira yatsopano moyo wobiriwira ndi mpweya wochepa, ndikulowa m'moyo wokhala ndi mpweya wochepa.
