Udaba lokungcoliswa kwepulasitiki seluphenduke undabuzekwayo kulezi zinsuku. Njengomunye umkhiqizo ongasetshenziswa kabusha, izikhwama ezilukiwe ze-PP zihehe ukunaka okusabalele ngokusebenza kwazo kwemvelo. Ngakho-ke yimiphi iminikelo evelele ukusebenziseka kabusha kwezikhwama ezilukiwe ze-PP ezinzuzweni zemvelo?
Okokuqala nje, singaxoxa ngezici eziyisisekelo zezikhwama ezilukiwe ze-PP ndawonye. I-PP, esingakwazi ngayo konke njenge-polypropylene, iyi-thermoplastic enamandla aqinile okuqinile, ukumelana namakhemikhali kanye nezindleko zokukhiqiza eziphansi. Lezi zikhwama zilula, ziqinile, futhi zingaklanywa ngosayizi abahlukahlukene kanye nomumo ukuze zivumelane nohlelo lokusebenza oluhlukile. Ngokuvamile zisetshenziselwa ukugcina nokuthutha okusanhlamvu, umanyolo, usimende nezinye izinto. Ezimpilweni zansuku zonke, abantu bavame ukuzisebenzisa ukugcina igilosa yasendlini noma beyothenga.
Okulandelayo, ake sihlaziye izinzuzo eziyingqayizivele zezikhwama ezilukiwe ze-PP mayelana nokuvikelwa kwemvelo. Uma ziqhathaniswa nezikhwama zepulasitiki ezilahlwayo zendabuko, izikhwama ezilukiwe ze-PP zigqama ngokuqina kwazo nokusebenziseka kabusha. Izikhwama zepulasitiki ezilahlwayo zivame ukulahlwa ngemva kokusetshenziswa kanye futhi zibe udoti okunzima ukuwehlisa, ngaleyo ndlela kubangele izinkinga ezinkulu zokungcoliswa kwemvelo; kuyilapho izikhwama ezilukiwe ze-PP zingasetshenziswa izikhathi eziningi ngokususa uthuli okwenziwa ngesandla nokuhlanza, ngaleyo ndlela Yehlisa kakhulu ukusetshenziswa kwepulasitiki iyonke. Ngaphezu kwalokho, lapho lezi zikhwama zifinyelela ekupheleni kwempilo yazo yesevisi, ngenxa yesakhiwo sazo esisodwa sezinto ezibonakalayo, inqubo yokuvuselela ilula. Angacutshungulwa kabusha ngemishini yobungcweti yokwenza kabusha imikhiqizo yepulasitiki emisha ukuze kuzuzwe ukugaywa kabusha kwensiza.
Akunakuzitshwa ukuthi sinengxoxo eyengeziwe mayelana nomthelela wemvelo wezikhwama ezilukiwe ze-PP ngesikhathi sokukhiqiza.
Esigabeni sokukhiqiza, iphansi kancane ekusetshenzisweni kwamandla okukhiqiza kanye nokukhishwa kwekhabhoni yezikhwama ezilukiwe ze-PP. Nakuba ukukhiqizwa kwanoma yimiphi imikhiqizo yepulasitiki kudla izinsiza futhi kudala izinga elithile lomthwalo wemvelo, kucatshangelwa ukusetshenziswa okuningi namandla okugaywa kabusha kwezikhwama ezilukiwe ze-PP, izindleko zemvelo phakathi nomjikelezo wayo wokuphila zizoncishiswa kakhulu. Ukwengeza, ukwamukela izinqubo zokukhiqiza ezivumelana nemvelo, njengokusetshenziswa kwamandla avuselelekayo noma izinyathelo zokuthuthukisa ukusebenza kahle kwamandla, kungase futhi kuthuthukise ukusebenza kwemvelo kwezikhwama ezilukiwe ze-PP.
Kufanele futhi siqaphele ukuthi nakuba izikhwama ezilukiwe ze-PP zinamaphuzu amaningi aqinile emvelo, noma kunjalo, aziyixazululi inkinga eyinhloko yokungcoliswa kwepulasitiki. Ukungcoliswa kwepulasitiki kuyinkinga eyinkimbinkimbi edinga imizamo ehlukahlukene ukuyixazulula. Izinyathelo ezihlanganisa ukunciphisa ukusetshenziswa kwemikhiqizo yepulasitiki, ukuthuthukisa ezinye izinto zokwakha, nokuqinisa ukuphathwa kwemfucuza yepulasitiki kuyizingxenye ezibalulekile.
Njengenketho evumelana nemvelo,U-PP weluka izikhwama ezingasetshenziswa kabushababe nezinzuzo ezisobala ekunciphiseni ukusetshenziswa kwepulasitiki kanye nomthelela wemvelo. Ngokusetshenziswa okuphusile kanye nokugaywa kabusha, singakwazi ukunweba ngempumelelo umjikelezo wempilo yalezi zikhwama futhi sinciphise umthwalo endaweni ezungezile.
Ngokuzayo, ngokuthuthuka kwezobuchwepheshe kanye nokwenza ngcono ukuqwashisa ngezenhlalo, sibheke ngabomvu ezisombululweni ezisha ukuze sakhe ngokuhlanganyela umhlaba oluhlaza futhi ozinzile.
Ngokuhlaziya okungenhla, singakwazi ukuthi izikhwama ezilukiwe ze-PP zinazo uchungechunge lwezinzuzo ezinhle mayelana nokuvikelwa kwemvelo. Kodwa-ke, ukuqaphela lezi zinzuzo kuzodinga umzamo ohlangene wethu, kanye nokucindezela okuqhubekayo kokuqwashisa ngemvelo kanye nezinqubo.
