nkhani

"Kukhala ndi moyo wopanda mpweya woipa" kwakhala nkhani yaikulu mu nthawi yatsopano. M'zaka zaposachedwapa, kuteteza chilengedwe chobiriwira, kusunga mphamvu, ndi kuchepetsa utsi wa mpweya pang'onopang'ono kwalowa m'masomphenya a anthu, ndipo kwakhalanso njira yatsopano yomwe ikuchirikizidwa komanso yotchuka kwambiri pakati pa anthu. Mu nthawi yobiriwira ndi yochepa mpweya, kugwiritsa ntchito zinthu zomwe zimawola kumaonedwa ngati chizindikiro chofunikira cha moyo wopanda mpweya woipa, ndipo kumalemekezedwa kwambiri ndikufalitsidwa.

Chifukwa cha kufulumira kwa moyo, mabokosi a pulasitiki otayidwa omwe amagwiritsidwa ntchito popanga chakudya chamasana, matumba apulasitiki, timitengo ta chakudya, makapu amadzi ndi zinthu zina zakhala zikufalikira kwambiri m'moyo. Mosiyana ndi mapepala, nsalu ndi zinthu zina, zinthu zapulasitiki zimatayidwa mwachilengedwe ndipo zimakhala zovuta kuziwononga. Ngakhale kuti zimapangitsa kuti miyoyo ya anthu ikhale yosavuta, kugwiritsa ntchito mopitirira muyeso kungayambitsenso "kuipitsa koyera". Pachifukwa ichi, zinthu zamoyo zomwe zimawonongeka ndi zinthu zomwe zimayamba kugwiritsidwa ntchito popanga zinthu zomwe zili ndi ubwino waukulu pankhani ya chilengedwe poyerekeza ndi zinthu zapulasitiki zachikhalidwe zomwe zimatayidwa. Zinthu zopangidwa pogwiritsa ntchito zinthu zamoyo zomwe zimawonongeka ndi zinthu zomwe zili ndi malo ambiri pamsika ndipo zimakhala zonyamulira zofunika kwambiri za lingaliro la moyo wamakono wopanda mpweya wambiri.

Pali mitundu yambiri ya zinthu zomwe zimawola, kuphatikizapoPCL, PBS, PBAT, PBSA, PHA,PLGA, PLA, ndi zina zotero. Lero tiyang'ana kwambiri pa zinthu zomwe zimayamba kuwonongeka zomwe zikubwera.

PLA, yomwe imadziwikanso kutipolylactic acid, CAS 26023-30-3ndi zinthu zopangira starch zomwe zimaphikidwa kuti zipange lactic acid, zomwe zimasanduka polylactic acid kudzera mu kapangidwe ka mankhwala ndipo zimakhala ndi biodegradability yabwino. Pambuyo pogwiritsidwa ntchito, zimatha kuwonongeka kwathunthu ndi tizilombo toyambitsa matenda m'chilengedwe, pamapeto pake zimapanga carbon dioxide ndi madzi popanda kuipitsa chilengedwe. Chilengedwe ndi chabwino kwambiri, ndipo PLA imadziwika ngati chinthu chosamalira chilengedwe chokhala ndi makhalidwe abwino kwambiri a zamoyo.

Zipangizo zazikulu za PLA ndi ulusi wa zomera zongowonjezedwanso, chimanga ndi zinthu zina zaulimi ndi zam'mbali, ndipo PLA ndi nthambi yofunika kwambiri ya zinthu zomwe zimawola zomwe zimatuluka. PLA ili ndi makhalidwe apadera pankhani ya kuuma ndi kuwonekera bwino. Ili ndi mgwirizano wamphamvu ndi zamoyo, imagwiritsa ntchito mosiyanasiyana, imakhala ndi mphamvu zakuthupi komanso zamakanika, ndipo imakwaniritsa zofunikira zosiyanasiyana zogwiritsidwa ntchito. Itha kugwiritsidwa ntchito m'njira zosiyanasiyana popanga zinthu zazikulu, yokhala ndi mphamvu yoletsa mabakiteriya ya 99.9%, zomwe zimapangitsa kuti ikhale chinthu chodalirika kwambiri chowola.

Asidi ya Polylactic (PLA)ndi chinthu chatsopano chobiriwira komanso chosunga chilengedwe chomwe chimapangidwa kuchokera ku lactic acid ngati zinthu zopangira; M'zaka zaposachedwa, PLA yagwiritsidwa ntchito pazinthu ndi minda monga udzu, mbale zophikira patebulo, zipangizo zophikira mafilimu, ulusi, nsalu, zipangizo zosindikizira za 3D, ndi zina zotero. PLA ilinso ndi kuthekera kwakukulu kopititsa patsogolo minda monga zida zothandizira zachipatala, zida zamagalimoto, ulimi, nkhalango, ndi kuteteza chilengedwe.

PLA yopangidwa ndiMakampani OgwirizanaNdi chinthu chabwino kwambiri pa tinthu tating'onoting'ono ta polylactic acid. Pogwiritsa ntchito zinthu zopangira polylactic acid zapamwamba kwambiri, pulasitiki ya PLA polylactic acid ndi ulusi wa PLA polylactic acid zimagwiritsidwa ntchito popanga zinthu zapulasitiki zathanzi, zosamalira khungu, zapamwamba, komanso zolimba zotsutsana ndi mabakiteriya. Zinthu zake zazikulu ndi monga zovala zamakono, nsapato ndi zipewa, mbale zodyera, makapu ndi maketulo, zolembera, zoseweretsa, nsalu zapakhomo, zovala zoyandikira ndi mathalauza, zinthu zapakhomo, zopukutira zouma ndi zonyowa, ndi zina zokhudzana ndi moyo wathu watsiku ndi tsiku.

Kutuluka kwaPLAkungathandize anthu kupewa kuipitsidwa koyera, kuchepetsa kuwonongeka kwa pulasitiki, ndikulimbikitsa kukwaniritsidwa bwino kwa kuchuluka kwa mpweya woipa komanso kusalowerera ndale. Cholinga cha Unilong Industry ndi "kutsatira momwe zinthu zilili masiku ano, kukhala ndi moyo wosawononga chilengedwe", kulimbikitsa mwamphamvu zinthu zomwe zingawonongeke, kupangitsa anthu kudya bwino komanso kukhala ndi moyo wathanzi, kulola kuwonongeka kwa mpweya kulowa m'mabanja ambiri, kutsogolera njira yatsopano ya moyo wobiriwira komanso wopanda mpweya woipa, ndikulowa mokwanira m'moyo wopanda mpweya woipa.
