Inkcazo yeMveliso

Ukhuseleko

Imathiriyeli yombhobho we-PE ayinayo ityhefu, ayinancasa, yeyezinto zokwakha eziluhlaza, ayinakuze inyuse.

Ukumelana nokubola

Ukuchasana okuphezulu ekuhlaselweni kwiintlobo ezahlukeneyo zeekhemikhali.Akukho ukubola kwe-electrochemical.

Umthamo wokuHamba oPhezulu

Udonga lwangaphakathi olugudileyo lulula kuthutho lwemibhobho.Phantsi kwemeko efanayo umthamo wonikezelo unokunyuswa ngama-30%.

Ilungele ukwakhiwa kunye nokufakwa

Umbhobho we-PE unokufakwa ngeendlela ezahlukeneyo ezingenamijelo, ngoko ke kulula kakhulu ukwakhiwa kunye nokufakwa.

Ubomi obude

Phantsi kweemeko eziqhelekileyo, ixesha lokuphila lingaphezulu kweminyaka engama-50.

Inkqubo ephantsi kunye neendleko zokugcina

Umbhobho we-PE awulungele nje ukuthutha kunye nokufakela, kodwa unciphisa ubunzima bomsebenzi wabasebenzi kunye nokuphucula ukusebenza kakuhle.

Indawo yesicelo

Ubonelelo lwamanzi ezidolophini

Imibhobho ye-PE ineenzuzo ezibanzi ezifana nokhuseleko, ucoceko, kunye nolwakhiwo olufanelekileyo, kwaye ibe ngumbhobho ofanelekileyo wonikezelo lwamanzi ezidolophini.

Amasimi okutya kunye neekhemikhali

Imibhobho ye-PE inokumelana neekhemikhali ezizodwa kwaye ingasetyenziselwa ukuthutha okanye ukukhutshwa kwe-asidi eyahlukeneyo, i-alkali kunye netyuwa, kunye nobomi obude benkonzo kunye neendleko eziphantsi zokufakela kunye nokugcinwa.

iNethiwekhi yokujonga umhlaba

Ukulungiswa komhlaba kufuna inani elikhulu lemibhobho yamanzi, kwaye imibhobho ye-PE inexabiso eliphantsi kwaye ifanele ukukhuthazwa ngamandla.

Ukuthuthwa kwentsimbi nodaka

Ukumelana nokunxiba kombhobho we-PE ngamaxesha angama-4 kumbhobho wensimbi, kwaye ingasetyenziselwa ngokubanzi ukuthutha i-ore, ukubhabha umlotha ovela kwizityalo zamandla, kunye nodaka lokukhupha umlambo.

Ukutshintshwa kwesamente, intsimbi kunye nemibhobho yentsimbi

Ukulungiswa kwemibhobho emidala efana nemibhobho yesamente kunye nemibhobho yentsimbi eyakhiwe ekuqaleni eyayibekwe esixekweni, imibhobho ye-PE inokufakwa ngokuthe ngqo kwimibhobho emidala ukuze itshintshwe ngaphandle kokugrumba okubanzi.Iindleko zeprojekthi ziphantsi kwaye ixesha lokwakha lifutshane, elilungele ngokukodwa imibhobho kwisixeko esidala.Ukubuyisela kwakhona.
