Imiphakathi Yemisebenzi YeMashini Yokudonsa Imvane: Ukulawula Kukudonsa Imvane KwiSifundo EsineSidingo Esikhulu
Imithi yokudonsa imvane ye-plastic ihlanya ekugcineni umzamo wokubeka ukudla , ngamathuba akhuthaza ukhokho lokufuna ubuhle nezimali ezihlukile. Bayakhi amafilimu amancane, amakhophe (umzekelo, amafilimu e-polyethylene) atholakala kuzo izinkunzi, izinto ezintsha, nezinto ezimfihlayo—amafilimu angahleliwe ngokulahlekwa kwe-moisture noma kwe-oxygen ukuze kugcinwe ubude bezinsuku zokudla. Ngokuthuthuka kwesimo sezintshisekelo, lezi ziphazamiso manje zihlupha phansi iplastics ezabalaziywa kanti nezinzima ezingavaleki (umzekelo, PLA), zinikela amabhrendi amandla ekhula izinhlangano ze-packaging ezenziwayo yezimali. Lokhu kubambisana nokuthuthuka kwebhaski yezimali kanye nezimali eziphathelene kusayensi kwenza kube yizinga elidingekayo kubengconyini be-packaging yezinto ezidla.
U indlu yesithembu kunikeza imikhono emakhulu yokuthutha kumashini okushisa amafilimu aluhlaza, ekhathazwa ngizidingo zokulima kamanje. Bayakha izinhlobo ezibalulekile zamafilimu olimi: ifilimu yegreenhouse eyohlala ikugcina ubushani nokukhupha izivuno ze-UV ukuze ikusine izimpahla, ne-filimu yomlunjwana eyahlukisa izimpunga futhi ikugcine ubushani bezuze. Izinhlelo ezihle kangaka zingakwamukela ubude bomgca wafilimu futhi zongeza izimboni ezisebenzayo (isibonelo, izimboni ezingavuki) ukuze zifane nempilo yendalo—kumaqabula aphelile asemadodakeni kuze kube semkhathini phansi. Ngokuthi kunesicelo esikhulu sokulima esinembili eningi, esihle, emhlabeni wonke, isicelo sezi zinhlobo ezithile zamafilimu (nezimboni ezenza kuzo) sizoba sithutha.
Izimboni zokushisa amafilimu aluhlaza zinezimangaliso eziphumelelayo e izinto ezisetyenziswa ngemini-neni kanye namasipala abalulekile . Ngemzuzu, bakhula icling film, izihluku zomthwalo, namathulini okuthenga—izinto ezinezidingo eziphakade kakhulu. Emgidi, bakhula izihluku zokuphepha (kwe-electronics, izimoto, nezimali zokubungaza) ezikhipha ukugayiswa ngexesha lokuthunyelwa, kwaye izihluku ezilula zokucindezela ukuhlanjulwa kwentonga. Inkinga yabo yokwenza iifilimu ngemiboniso eyahlukileyo, ukugqibelela nokubhuda, kuvumela ukuba bafanele amathiphu asemgideni, ekunika imithombo yokufumana imali engaphezu kwegunya lesebenzi elisebenziswe ngokuchanekileyo.
