Thumba lowonongeka limatanthawuza pulasitiki yomwe imawonongeka mosavuta m'chilengedwe pambuyo powonjezera zowonjezera zowonjezera (monga wowuma, wowuma wosinthidwa kapena mapaipi ena, photosensitizers, biodegradable agents, etc.) panthawi yopanga kuti achepetse kukhazikika kwake.
1. Njira yosavuta ndiyo kuyang'ana maonekedwe
Zida zopangira matumba apulasitiki owonongeka ndiPLA, PBAT,wowuma kapena mineral powder materials, ndipo padzakhala zizindikiro zapadera pa thumba lakunja, monga wamba"PBAT+PLA+MD".Pamatumba apulasitiki osawonongeka, zopangira ndi PE ndi zida zina, kuphatikiza "PE-HD" ndi zina zotero.
2. Yang'anani moyo wa alumali
Chifukwa cha kuwonongeka kwachilengedwe kwa zida zowonongeka zamatumba apulasitiki, matumba apulasitiki omwe amatha kuwonongeka amakhala ndi alumali, pomwe matumba apulasitiki osawonongeka nthawi zambiri sakhala ndi alumali.Izi zitha kupezeka pamapaketi onse akunja a thumba la pulasitiki, ndipo nthawi zina zimakhala zovuta kudziwa.
3. Kununkhiza ndi mphuno
Matumba ena apulasitiki osawonongeka amapangidwa powonjezera wowuma, motero amamva fungo lonunkhira bwino.Ngati inukununkhiza fungo la chimanga, chinangwa, etc.,zikhoza kutsimikiziridwa kuti ndi biodegradable.Inde, kusanunkhiza sikutanthauza kuti ndi matumba wamba apulasitiki.
4. Chizindikiro cha zinyalala zowonongeka chili ndi chizindikiro chogwirizana cha chilengedwe pathumba lapulasitiki lowonongeka
wokhala ndi chizindikiro chobiriwira chokhala ndi mapiri omveka bwino, madzi obiriwira, dzuwa, ndi mphete khumi.Ngati ndi thumba la pulasitiki logwiritsira ntchito chakudya, liyeneranso kusindikizidwa ndi chilolezo chachitetezo cha chakudya cha QS cholembedwa kuti "chakudya".
5. Kusungirako matumba a zinyalala omwe amatha kuwonongeka ndi biodegradable amakhala ndi alumali moyo wa miyezi itatu yokha.
Ngakhale sizikugwiritsidwa ntchito, kuwonongeka kwachilengedwe kudzachitika mkati mwa miyezi isanu.Pofika miyezi isanu ndi umodzi, matumba apulasitiki adzakhala atakutidwa ndi "chipale chofewa" ndipo sangathe kugwiritsidwa ntchito.Pamikhalidwe ya kompositi, ngakhale matumba apulasitiki ongowonongeka kumene amatha kuonongeka m'miyezi itatu yokha.
Zinthu zomwe zimatha kuwonongeka zimagwiritsidwa ntchito makamaka m'minda monga mapulasitiki osawonongeka komanso ulusi wowonongeka.Zipangizo zowonongeka zimakhala ndi kulimba kwambiri komanso kukana kutentha, ntchito yabwino yokonzekera, ndipo ntchito yawo imafika pamlingo wa mapulasitiki ambiri.Zitha kugwiritsidwa ntchito popanga zida zonyamula, ziwiya zophikira, mafilimu aulimi, zinthu zotayidwa, zaukhondo, ulusi wansalu, thovu la nsapato ndi zovala, ndipo akuyembekezeka kugwiritsidwa ntchito m'magawo apamwamba kwambiri monga zida zamankhwala, optoelectronics, ndi mankhwala abwino. .Komano, zinthu zomwe zimatha kuwonongeka ndi biodegradable zili ndi zabwino zambiri pazambiri zongowonjezwdwanso, kuteteza chilengedwe kwa mpweya wochepa, kuteteza mphamvu ndi kuchepetsa utsi.
