Okwangoku, umgangatho weekomityi zephepha ezilahlayo kwiimarike azilingani, ingozi efihliweyo inkulu.Abanye abenzi beekomityi zephepha bongeza izikhanyisi ze-fluorescent ukuze zibonakale zimhlophe.Izinto zefluorescent zibangela ukuba iiseli ziguquke kwaye zibenakho umhlaza xa zingena emzimbeni.Ukuze wenze indebe yamanzi, ingaphakathi lendebe lifakwe ifilimu ye-polyethylene engenamanzi.I-polyethylene yeyona khemikhali ikhuselekileyo ekusetyenzweni kokutya, kodwa ukuba izinto ezikhethiweyo azilunganga okanye itekhnoloji yokucubungula ayifikanga kwinqanaba, iikhompawundi ze-carbonyl zinokuthi zenziwe nge-oxidized ngexesha lokunyibilika okanye ukugquma i-polyethylene kwikomityi yephepha, kwaye i-carbonyl ikhompawundi ayiguquguquki. ngokulula kwiqondo lobushushu begumbi, kodwa inokumka ngumphunga xa ikomityi yephepha izaliswe ngamanzi ashushu, ukuze abantu bawanuke.Nangona akukho zifundo zokuqinisekisa ukuba iikhompawundi ze-carbonyl ezikhutshwe kwiikomityi zephepha ziya kuzisa nayiphi na ingozi emzimbeni womntu, kodwa kuhlalutyo lwethiyori ngokubanzi, ukuthathwa kwexesha elide kule ngqungquthela yezinto eziphilayo, kufuneka kube yingozi kumzimba womntu.Ukukhathazeka ngakumbi kukuba ezinye iikomityi zephepha ezikumgangatho ophantsi zisebenzisa i-polyethylene ehlaziyiweyo, kwinkqubo yokuhlaziya iya kuba neenguqu eziqhekezayo, ezikhokelela kwinani leekhompawundi ezinobungozi, ekusebenziseni ukufuduka kwamanzi ngokulula.Urhulumente unqabela ngokucacileyo ukusetyenziswa kwe-polyethylene ehlaziyiweyo kwipakethe yokutya, kodwa ngenxa yexabiso eliphantsi, ezinye iifektri ezincinci zokulondoloza iindleko, zisasebenzisa ngokungekho mthethweni.
Ukuze ufezekise ikomityi yephepha ekuveliseni umphumo wokumelana namanzi, iya kufakwa ngomgca wefilimu ye-polyethylene enganyangekiyo yamanzi eludongeni lwangaphakathi.I-Polyethylene yikhemikhali ekhuselekileyo ekusetyenzisweni kokutya, kunzima ukuyinyibilika emanzini, ayinayo ityhefu, engenancasa.Kodwa ukuba into ekhethiweyo ayilungile, okanye iteknoloji yokucubungula, kwi-polyethylene eshushu enyibilikayo okanye i-coating kwinkqubo yekomityi, inokuthi i-oxidized kwi-carbonyl compounds.Iikhompawundi zeCarbonyl aziphumi lula kwiqondo lobushushu begumbi, kodwa ziyenzeka xa iikomityi zephepha zizaliswe ngamanzi ashushu, ngoko ke abantu banuka kamnandi.Ukungeniswa kwexesha elide kule khompawundi yezinto eziphilayo kuyingozi empilweni.Ezinye iikomityi zephepha ezikumgangatho ophantsi zenziwe nge-polyethylene esetyenzisiweyo, eya kuvelisa iikhompawundi ezininzi ezinobungozi kwinkqubo yokulungiswa kwakhona.Urhulumente unqabela ngokucacileyo ukusetyenziswa kwe-polyethylene ehlaziyiweyo kwipakethe yokutya, kodwa ngenxa yexabiso eliphantsi, ezinye iifektri ezincinci zokulondoloza iindleko, zisasebenzisa ngokungekho mthethweni.Okwangoku, umgangatho wesizwe womgangatho weekomityi zephepha ufuna kuphela ukuvavanya i-microorganisms, kodwa akukho vavanyo lweekhemikhali, kuba uvavanyo lunzima kakhulu kwaye lunzima ukwenza.Ezinye iikomityi zephepha ngenxa yomgangatho ophantsi we-pulp, iimveliso ezimhlophe zomfanekiso okongezwa okukhulu kwebleach fluorescent, enomngcipheko womhlaza.Ucebise ukuba iikomityi zephepha ezilahlwayo azinakusetyenziswa ngakumbi, njengezona zingcono ngamanzi abandayo, ukunciphisa ukuguquguquka kweekhemikhali eziyingozi.
