Yofalitsidwa pa Seputembala 25, 2024 ndi Yidan Zhong
PMU (polymer-metal hybrid unit, pamenepa chinthu china chake chomwe chimawola), chingapereke njira ina yobiriwira m'malo mwa mapulasitiki achikhalidwe omwe amakhudza chilengedwe chifukwa cha kuwonongeka pang'onopang'ono.

Pankhani yokonza zodzoladzola zosawononga chilengedwe, PMU ndi chinthu chapamwamba chosawononga chilengedwe chomwe chimaphatikiza kulimba ndi magwiridwe antchito a ma CD achikhalidwe ndi chidziwitso cha chilengedwe cha ogula amakono. Chopangidwa ndi pafupifupi 60% ya zinthu zosawononga zachilengedwe monga calcium carbonate, titanium dioxide ndi barium sulfate, komanso 35% ya PMU polymer yokonzedwa mwathupi ndi zowonjezera 5%, zinthuzo zimatha kuwola mwachilengedwe pansi pa mikhalidwe ina, zomwe zimachepetsa kwambiri kutayira zinyalala ndi nyanja.
Ubwino wa ma CD a PMU

Kuzindikirika padziko lonse lapansi: Zipangizo za PMU zatchuka padziko lonse lapansi, monga momwe zasonyezedwera ndi satifiketi yawo yopambana ya ISO 15985 ya anaerobic biodegradation ndi satifiketi ya Green Leaf, yomwe ikuwonetsa kudzipereka kwawo ku miyezo ya chilengedwe.
Tsogolo la PMU mu ma CD okongoletsera
Pali makampani omwe kale akufufuza ndikugwiritsa ntchito ma CD a PMU. Akuyesetsa kupeza njira zogwiritsira ntchito njira zosungira ma CD, ndipo kufunikira kwa PMU ndi zinthu zina zofananira zosamalira chilengedwe kukuyembekezeka kuwonjezeka pamene ogula akuyamba kuzindikira kwambiri za kuipitsidwa kwa pulasitiki.
Pamene maboma padziko lonse lapansi akukhwimitsa malamulo okhudza mapulasitiki ogwiritsidwa ntchito kamodzi ndipo ogula akufuna zinthu zosawononga chilengedwe, makampani odzola akhoza kuona msika waukulu wa ma CD a PMU. Ndi kupita patsogolo kwaukadaulo komanso ndalama zochepa zopangira, PMU idzakhala imodzi mwa zisankho zazikulu za makampani okongoletsa.
Kuphatikiza apo, kusinthasintha kwa zinthu za PMU kumalola kugwiritsa ntchito zinthu zina kupatula zotengera zokhazikika zachikhalidwe, kuphatikizapo matumba osinthasintha, matepi ndi mapangidwe ovuta kwambiri a ma CD. Izi zimatsegula mwayi wambiri wopezera mayankho a ma CD omwe samangoteteza malonda okha, komanso amawonjezera luso la mtundu wonse.
