Kubomi bethu bemihla ngemihla, iikomityi zephepha ziye zaba yinto eqhelekileyo.Nokuba yivenkile yekofu, yindlu yeti okanye yindibano yosapho, sonke sisebenzisa iikomityi zephepha.Nangona kunjalo, ngaba ukhe wazibuza ukuba kutheni ezi komityi zephepha ziqinisekisiwe ukuba azinakuvuza?Konke oku kungenxa yesitshixo sekomityi yephepha lemathiriyeli ekrwada - iphepha eliqatywe ngePE.
PE iqatywe iphepha rollyimveliso yephepha elicwangcisiweyo eligqunywe ngomgca wefilimu ye-polyethylene kwiphepha lesiseko.Umsebenzi walo maleko wefilimu kukuphucula ukusebenza kwamanzi kwikomityi yephepha, kunye nokuphucula ukumelana nobushushu kunye namandla ekomityi yephepha.Ke, iphepha eligqunywe nge-PE liqinisekisa njani ukuba ikomityi yephepha ayivuzi?
Okokuqala, ukukhethwa kwezinto eziphathekayo zephepha elifakwe kwi-PE kubaluleke kakhulu ekusebenzeni kwayo okungangeni manzi.Ifilimu ye-Polyethylene yi-resin yokwenziwa kunye nobunzima obuphezulu be-molecular, enomsebenzi ogqwesileyo wokungena kwamanzi kwaye inokuthintela ngokufanelekileyo umswakama ukuba ungangeni ngaphakathi kwikomityi yephepha.Ngelo xesha, iphepha elifakwe kwi-PE liye laphathwa ngokukodwa ukwenza udibaniso phakathi kwefilimu kunye nephepha ngokuqinileyo, ngaloo ndlela kugwenywe ukungena kwamanzi.
Okwesibini, itekhnoloji yokucubungula iphepha elifakwe kwi-PE nayo idlala indima ephambili ekusebenzeni kwayo okungangeni manzi.Ngethuba lenkqubo yokuvelisa, umatshini wokulambisa ngokulinganayo utshiza ifilimu ye-polyethylene etyhidiweyo kwiphepha lesiseko ngokusebenzisa umoya ophezulu woxinzelelo.Le ndlela yokucubungula yenza ibhondi eqinile phakathi kwefilimu kunye nephepha, ngaloo ndlela iqinisekisa ukusebenza kwamanzi kwindebe yephepha.
Ekugqibeleni, ukwenzela ukuba kuqinisekiswe ngakumbi ukuba iikomityi zephepha azinamanzi, ukuhlolwa okungqongqo kunye nokulawula kuyadingeka ngexesha lokucubungula abalandeli bekomityi yephepha.Ngokomzekelo, imiphetho yeekomityi zephepha kufuneka inqunywe ngokuchanekileyo kunye nomhlaba ukuqinisekisa ukutywinwa okulungileyo.Ngelo xesha, umgangatho weekomityi zephepha kufuneka uhlolwe ngokungenamkhethe ngexesha lenkqubo yokuvelisa ukuze kuqinisekiswe ukuba bahlangabezana nemigangatho esemgangathweni efana nokunganyangeki kwamanzi, ukumelana nobushushu kunye namandla.
Ngeempawu zayo ezikhethekileyo zemathiriyeli kunye nenkqubo yokwambathisa yobuchwephesha, iphepha le-PE eligqunyiweyo liqinisekise ngempumelelo umsebenzi wokungangeni kwamanzi wendebe yephepha.Ukusebenza kwayo ekungangeni manzi, ukuqina, ukhuseleko kunye nokusebenziseka kwakhona kwenza iphepha le-PE eligqunyiweyo libe lolona khetho lufanelekileyo lokusetyenziswa ngokubanzi kwimveliso yekomityi yephepha.
