Losindikizidwa pa Seputembara 25, 2024 ndi Yidan Zhong
PMU (polymer-metal hybrid unit, pamenepa ndi zinthu zinazake zowola), imatha kupereka njira yobiriwira yofananira ndi mapulasitiki achikhalidwe omwe amakhudza chilengedwe chifukwa chakuwonongeka pang'onopang'ono.
Kumvetsetsa PMU muZodzikongoletsera Packaging
Pankhani ya zodzikongoletsera zokometsera zachilengedwe, PMU ndi chinthu chotsogola chosasinthika chomwe chimaphatikiza kulimba ndi magwiridwe antchito azinthu zachikhalidwe ndi chidziwitso cha chilengedwe cha ogula amakono. Wopangidwa ndi pafupifupi 60% zinthu zakuthupi monga calcium carbonate, titanium dioxide ndi barium sulfate, komanso 35% polima polima PMU ndi 5% zowonjezera, zinthuzo zikhoza kuwola mwachibadwa pansi pazifukwa zina, kuchepetsa kwambiri kulemedwa kwa nthaka ndi nyanja.
Ubwino wa phukusi la PMU
Biodegradability: Poyerekeza ndi mapulasitiki achikhalidwe, omwe amatenga zaka mazana ambiri kuti awole, ma phukusi a PMU amawonongeka pakatha miyezi ingapo. Izi zikugwirizana bwino ndi kufunikira kwa mayankho okhazikika pamakampani okongoletsa.
Kuzungulira kwa moyo wochezeka ndi zachilengedwe: Kuchokera pakupanga mpaka kutaya, kuyika kwa PMU kumaphatikizapo njira yokhazikika yomwe ndiyosangalatsa zachilengedwe. Simafunikira mikhalidwe yapadera yowonongeka, imakhala yopanda poizoni pamene itenthedwa ndipo imasiya zotsalira zikaikidwa.
Kukhalitsa ndi Kugwira Ntchito: Ngakhale kuti ndi zachilengedwe zokomera zachilengedwe, kuyika kwa PMU sikusokoneza kulimba ndi magwiridwe antchito. Imalimbana ndi kusinthasintha kwa madzi, mafuta ndi kutentha, zomwe zimapangitsa kuti zikhale zoyenera kusunga ndi kuteteza zodzoladzola.
Kuzindikirika kwapadziko lonse: Zida za PMU zakopa chidwi ndi kuzindikirika padziko lonse lapansi, monga zikuwonetseredwa ndi satifiketi yawo yopambana ya ISO 15985 anaerobic biodegradation ndi satifiketi ya Green Leaf, zomwe zikuwonetsa kudzipereka kwawo ku miyezo ya chilengedwe.
Tsogolo la PMU muzopaka zodzikongoletsera
Pali makampani omwe akufufuza kale ndikugwiritsa ntchito PMU. Akuyesetsa kupeza njira zopezera mayankho okhazikika, ndipo kufunikira kwa PMU ndi zida zofananira ndi zachilengedwe zikuyembekezeka kuchulukirachulukira pomwe ogula akudziwa zambiri zakuwonongeka kwa pulasitiki.
Pamene maboma padziko lonse lapansi akukhwimitsa malamulo ogwiritsira ntchito mapulasitiki ogwiritsidwa ntchito kamodzi ndipo ogula amafuna zinthu zambiri zowononga zachilengedwe, makampani odzola mafuta amatha kuona msika waukulu wa PMU. Ndi kupita patsogolo kwaukadaulo komanso kutsika mtengo kopanga, PMU ikhala imodzi mwazosankha zazikulu zamitundu yokongola.
Kuphatikiza apo, kusinthasintha kwa zida za PMU kumalola kugwiritsa ntchito kupitilira zotengera zachikhalidwe, kuphatikiza matumba osinthika, matepi komanso mapangidwe ovuta kwambiri. Izi zimatsegula mwayi wambiri wopangira mayankho omwe samangoteteza katunduyo, komanso amakulitsa chidziwitso chamtundu wonse.
