Kulokhu okuthunyelwe kwebhulogi, sizobhekisisa ukukhiqizwa kokufakwa kwepulasitiki futhi sikhombe ezinye zezinto eziyingozi ezisetshenziswayo.

Hlala ubukele ukuze uthole okwengeziwe!

Kuyini ukupakisha kwepulasitiki?
Ukupakisha kwepulasitiki kuwuhlobo lwamaphakheji owenziwe ngepulasitiki.Isetshenziselwa ukugcina nokuvikela imikhiqizo emonakalweni nasekungcolisweni.

Ukupakishwa kwepulasitiki kuvame ukukhethwa ngenxa yokuthi ayisindi, aqinile futhi amelana nomswakama.Kungabuye kucace noma kube nemibala ukukhombisa imikhiqizo ngaphakathi.Ezinye izinhlobo zokupakishwa kwepulasitiki zingagaywa kabusha, kanti ezinye azikwazi.

Kwenziwa kanjani ukupakishwa kwepulasitiki?
Ukupakishwa kwepulasitiki kwenziwa ngama-polymers, okungama-molecule amaketanga amade.Nansi inqubo:

isinyathelo #1
Ama-polymers ama-molecule amaketanga amade, futhi ukupakishwa kwepulasitiki kwenziwa ngalawa ma-polymer.Isinyathelo sokuqala kule nqubo ukudala amaketanga e-polymer.Lokhu kwenziwa efekthri lapho izinto ezingavuthiwe zixutshwa futhi zishiswe kuze kube uketshezi.Uma ama-polymers esewuketshezi, angakhiwa abe yisimo esifisayo.

Isinyathelo #2
Ngemuva kokwakhiwa kwamaketanga e-polymer, adinga ukupholiswa futhi aqiniswe.Lokhu kwenziwa ngokuwadlulisa ochungechungeni lwamarola.Ama-roller afaka ingcindezi epulasitiki encibilikisiwe, okwenza ukuthi iqine futhi ithathe isimo esifunayo.

Isinyathelo #3
Isinyathelo sokugcina siwukwengeza ukuthinta kokuqeda, njengokuphrinta noma amalebula.Lokhu ngokuvamile kwenziwa ngomshini, nakuba okunye ukupakisha kungenziwa ngesandla.Uma isipakishiwe, ingasetshenziselwa ukugcina nokuthutha umkhiqizo.

Yile ndlela ipulasitiki eyenziwa ngayo ibe ukupakisha.Lena inqubo elula kakhulu.Manje ake sibone ukuthi yimaphi amakhemikhali asetshenziswa kule nqubo.

Imaphi amakhemikhali asetshenziswa emaphaketheni epulasitiki?
Kunezinhlobonhlobo zamakhemikhali angasetshenziswa emaphaketheni epulasitiki, kodwa amanye ajwayelekile ahlanganisa:

I-Bisphenol A (BPA):Ikhemikhali esetshenziselwa ukwenza amapulasitiki abe nzima futhi amelane kakhulu nokuphahlazeka.I-BPA ikhonjiswe ukuthi inemiphumela efana ne-hormone ezilwaneni, futhi kunobunye ubufakazi bokuthi ingase ibangele nezinkinga zempilo kubantu.
Ama-Phthalates:Iqembu lamakhemikhali asetshenziselwa ukwenza amapulasitiki athambile futhi anwebeka kakhulu.Ama-Phthalates axhunyaniswe nezinkinga zezempilo ezahlukahlukene, okubandakanya ukungahambi kahle kokuzala kanye nokungazali.
Ama-Perfluorinated Compounds (PFCs):Amakhemikhali asetshenziselwa ukwenza izinto ezixosha amanzi namafutha kumapulasitiki.I-PFC ihlotshaniswa nomdlavuza, ukulimala kwesibindi kanye nezinkinga zokuzala.
Ama-Plasticizers:Amakhemikhali afakwa kumapulasitiki ukuze awenze athambe futhi anwebeke kakhulu.Ama-Plasticizer angaphuma emaphaketheni angene ekudleni noma eziphuzweni.

Ngakho-ke, lawa amanye amakhemikhali asetshenziswa kakhulu emaphaketheni epulasitiki.Njengoba ubona, eziningi zazo zingaba yingozi empilweni yomuntu.Kungakho kubalulekile ukuqonda ubungozi bokupakishwa kwepulasitiki futhi uthathe izinyathelo zokukugwema.

Izinzuzo zokusebenzisa ukupakisha kwepulasitiki
Kunezinzuzo ezithile zokusebenzisa amaphakheji epulasitiki.Ukupakishwa kwepulasitiki kuvame ukukhethwa ngoba:

Okungasindi:Ukufakwa kwepulasitiki kulula kunezinye izinhlobo zokupakisha njengengilazi noma insimbi.Lokhu kwenza ukuthunyelwa kushibhe futhi kube lula ukuphatha.
Okuhlala isikhathi eside:Iphakethe lepulasitiki liqinile futhi alilimali kalula.Lokhu kusiza ukuvikela umkhiqizo ngaphakathi ekuqhekekeni nasekungcoleni.
Ukuvikela umswakama:Ukupakishwa kwepulasitiki kuwubufakazi bomswakama futhi kusiza ukugcina okuqukethwe komile futhi kukusha.
Iyasebenziseka kabusha:Izinhlobo ezithile zokupakishwa kwepulasitiki zingagaywa kabusha, okusiza ekunciphiseni ukumosha.
Ngakho-ke lezi ezinye zezinzuzo zokusebenzisa amaphakheji epulasitiki.Nokho, ukukala lezi zinzuzo ngezingozi ezingase zibe khona empilweni yomuntu kubalulekile.

Izingozi zokusebenzisa amaphakheji epulasitiki
Njengoba sesibonile, kunezingozi eziningi ezihlobene nokusebenzisa amaphakheji epulasitiki.Lokhu kubandakanya:

Amakhemikhali Ayingozi:Amakhemikhali amaningi asetshenziswa emaphaketheni epulasitiki ayingozi empilweni yomuntu.Lokhu kufaka i-BPA, ama-phthalates nama-PFC.
I-Leaching:Ama-Plasticizer angaphuma emaphaketheni afake ukudla noma isiphuzo.Lokhu kwandisa inani lamakhemikhali ayingozi ochayeka kuwo.
Ukungcola:Ukupakishwa kwepulasitiki kungangcolisa okuqukethwe, ikakhulukazi uma kungahlanzwanga kahle noma kungahlanjululwanga.
Ngakho lezi ezinye zezingozi zokusebenzisa amaphakethe epulasitiki.Lezi zingozi kufanele zicatshangelwe ngaphambi kokuthatha isinqumo sokuthi uzosebenzisa amaphakethe epulasitiki.

Isiphetho
Nakuba izinombolo eziqondile kunzima ukuzicisha, singalinganisela ukuthi amakhemikhali angaba ngu-10-20 ayadingeka ukwenza ukupakishwa kwepulasitiki okujwayelekile.

Lokhu kusho izindawo eziningi zokuxhumana ezingase zibe nobuthi obuyingozi nezinto ezingcolisayo.

Xhumana nathi uma ufuna inketho esimeme futhi enobungani bemvelo.
