Izimbangela nezixazululo zezikhwama zepulasitiki ezilukiweyo eziphukayo nezintekenteke

Njengento yokupakisha evamile,izikhwama zepulasitiki ezilukiwezisetshenziswa kabanzi ekuphileni kwansuku zonke. Kodwa-ke, abantu abaningi baye bahlangabezana nenkinga yezikhwama zepulasitiki eziphukayo neziphukayo. Izimbangela eziyinhloko zenkinga zizokwethulwa ngezansi, futhi ezinye izixazululo zizonikezwa ukuze zisisize ngokuphumelelayo ukuphila kwezikhwama ezilukiwe zepulasitiki.
Isikhwama esilukiwe sepulasitiki wuhlobo lwesikhwama esenziwe ngemicu yepulasitiki efana ne-polypropylene (PP). Nakuba zinezinga eliphezulu lokumelana nemihuzuko namandla aqinile, ngezinye izikhathi sithola ukuthi ziba brittle futhi ziphuke kalula. Lokhu kwenzeka ngezici ezihlukahlukene, futhi nazi ezinye zezizathu eziyinhloko.
1. Ukukhanyisa
Lapho isikhwama esilukiwe sepulasitiki sichayeka elangeni, i-polymer ekuso izobhidlika kancane kancane, ibangele ukuthi isikhwama sibe brittle. Imisebe ye-UV evezwe ngokuqondile ebusweni besikhwama esivela elangeni ingabangela ukuphuka kwamaketanga e-polymer, okwenza ipulasitiki ilahlekelwe amandla ayo okuqala kanye nokuguquguquka.
Isixazululo: Gwema ukubeka obala isikhwama sepulasitiki esilukiwe ekuqondiseni ilanga isikhathi eside, bese uzama ukusigcina noma ukusisebenzisa endaweni epholile, enomthunzi.
2. I-oxidation
Umoya-mpilo futhi ungenye yezimbangela zokuguga kanye nokuba brittleness kwezikhwama zepulasitiki ezilukiwe. Ama-molecule e-oksijeni angakwazi ukudiliza amaketanga e-polymer, ngakho ukwakheka kwamangqamuzana esikhwama kuyashintsha kancane kancane, kusenze sibe ntekenteke.
Isixazululo: Gcina izikhwama zepulasitiki ezilukiweyo endaweni evaliwe, engenamoya ukuze unciphise ukuthintana kwesikhwama nomoya futhi usize ukwehlisa izinga isikhwama esikhipha ngaso oksijini.
3. Amazinga okushisa aphansi
Amazinga okushisa aphansi angenza izikhwama zepulasitiki ezilukiwe zibe brittle futhi zibe brittle. Emazingeni okushisa aphansi, ukunyakaza kwamangqamuzana epulasitiki kunciphisa, kunciphisa ukuguquguquka kwesikhwama, okuholela engozini eyengeziwe yokuqhekeka nokuphuka.
Isixazululo: Gwema ukushiya isikhwama sepulasitiki esilukiwe endaweni ebanda kakhulu bese uzama ukusisebenzisa ekamelweni lokushisa. Ngezindawo ezisezingeni eliphansi ezidinga ukusetshenziswa, khetha izikhwama zepulasitiki ezilukiweyo ezinokuguquguquka okungcono nokusebenza.
4. Izincibilikisi zamakhemikhali
Izikhwama zepulasitiki ezilukiweyo zivame ukuchayeka ezincibilikilweni zamakhemikhali, njengotshwala, izihlanzi ezine-asidi, njll., ezingacekela phansi ukwakheka kwepulasitiki, kunciphise amandla ayo okusebenza, futhi kwandise ingozi yokubola nokuphuka.
Isixazululo: Gwema ukubeka obala izikhwama zepulasitiki ezilukiweyo kuzincibilikisi zamakhemikhali bese uzama ukukhetha isikhwama esifanele ukugcina izinto ezingaba yingozi.
Ukuze sandise impilo yesevisi yezikhwama ezilukiwe zepulasitiki, kufanele siqonde ngokugcwele izizathu ezenza zibe brittle futhi zibe brittle, futhi sithathe izixazululo ezihambisanayo. Ukusetshenziswa nokugcinwa ngendlela efanele, ukugwema ukuchayeka elangeni eliqondile, ukunciphisa ukuthintana nomoya, ukugwema ukuthintana nezimo ezishisayo nezincibilikisa amakhemikhali kuyizinyathelo ezibalulekile zokuvikela izikhwama ezilukiwe zepulasitiki.
Ngaphezu kwalokho, kunezinyathelo ezengeziwe ezingathathwa ukuze kunwetshwe impilo yezikhwama ezilukiwe zepulasitiki:
1. Ukusebenzisa nokuphatha ngendlela efanele: Gwema ukufaka izinto ezisindayo ngokweqile noma ezicijile esikhwameni esilukiwe sepulastiki, ukuze ungakhulisi umthwalo esikhwameni noma ubangele ukuba umzimba wesikhwama uklwebhe. Ngesikhathi esifanayo, ungahuduli isikhwama esilukiwe sepulasitiki phansi ukuze unciphise ukuguga nokudabuka kwesikhwama ngezinto zangaphandle.
2. Ukuhlanza nokugcinwa njalo: Hlanza isikhwama sepulasitiki eselukiwe njalo, ungasebenzisa amanzi anensipho athambile noma okokuhlanza izingubo ukuze uhlanze indawo engaphezulu yesikhwama, futhi usihlanze kahle. Ukugcina isikhwama sihlanzekile kunganciphisa ukuguguleka kwepulasitiki ngokungcola namakhemikhali anamathela phezulu.
3. Khetha izikhwama zepulasitiki ezilukiwe zekhwalithi ephezulu: Lapho uthenga izikhwama zepulasitiki ezilukiwe, khetha izinhlobo nezinto zokwakha ezinekhwalithi ethembekile nokuqina okuhle. Izikhwama ezisezingeni eliphezulu zimelana kakhulu nokuguga kanye ne-embrittlement, futhi zingagcina ikhwalithi enhle isikhathi eside.
4. Cabangela ezinye izindlela ezibolayo: Ukunciphisa umthelela endaweni ezungezile, cabanga ukusebenzisa izikhwama zepulasitiki ezilukiweyo ezingaboli esikhundleni sezikhwama zepulasitiki zendabuko. Izikhwama ezibolayo zingabhidlika ngokushesha, zinciphise izinkinga zokungcoliswa kwepulasitiki.
Ngokuthatha lezi zinyathelo ezingenhla, ungakwazi ukunweba ngokuphumelelayo impilo yesevisi yezikhwama ezilukiwe zepulasitiki futhi unciphise inkinga yokukhwabanisa kanye nokuqina. Ngesikhathi esifanayo, kufanele futhi sikhuthaze ukuthuthukiswa kwezixazululo zokupakisha ezinobungani bemvelo nezisimeme, sinciphise isidingo sezikhwama ezilukiwe zepulasitiki, futhi sibambe iqhaza emvelweni womhlaba.
