Ukusukela ngo-1998 iMunich International Coal Union LGU iKomiti yokuhanjiswa kwerhasi intlanganiso efanayo yacetyiswa ngamandla ukuba kusetyenziswe umbhobho werhasi ongcwatyiweyo we-PE njengombhobho wokuhambisa kunye nokuhanjiswa, emva kweminyaka engaphezu kwe-10 yophando lwesayensi kunye noyilo lophuhliso kwihlabathi liphela, umbhobho we-PE uphuhliswe waba ngumkhwa iintlobo ezininzi, ezininzi ezisetyenziswayo eziphambili zombhobho.Phantse kwiminyaka engama-20, imathiriyeli yemibhobho yeplastiki iyenyuka hayi nje ngobuninzi, kwaye ifumana uphuhliso olukhulu kakhulu kwinzala kunye neenkcukacha.Umbhobho we-PE Umbhobho we-PE usetyenziselwa ubukhulu becala imibhobho kamasipala kunye nangaphandle yogutyulo kunye nemibhobho yogutyulo lwezakhiwo, imibhobho yogutyulo kunye nemibhobho yokuhambisa amanzi amdaka amaziko okucoca ugutyulo, kunye nemikhono yokhuselo yemibhobho engaphantsi komhlaba kunye neentambo zonxibelelwano.
E-China, imibhobho ye-PE ihlelwa ikakhulu kumbhobho we-PE wokuhanjiswa kwamanzi kunye negesi, unikezelo lwamanzi kunye nokufudumeza umbhobho we-PE, umbhobho welindle wokwakha, umbhobho wogutyulo wamanzi amdaka, umbhobho wentambo kunye nentambo yentambo ye-PE, umbhobho we-PE wokunkcenkceshela, umbhobho we-PE woshishino kunye Umbhobho wekhoyili we-PE.Umbhobho we-PE kunye nokuveliswa kokusetyenziswa kwamandla kancinane, ungcoliseko lwendalo oluncinci, ukusebenza kakuhle kwemveliso kunye nezinye iingenelo, ezithandwa kakhulu ngabantu kunye namasebe achaphazelekayo achaphazelekayo.UMphathiswa woKwakha weRiphabhlikhi yaBantu baseTshayina naye ukhuphe isaziso sokomeleza ulawulo kunye nokukhuthazwa kokuveliswa kwemibhobho yeplastiki.
Kwiminyaka yakutshanje, i-85% yemibhobho yokuhambisa amanzi yangaphakathi, imibhobho yokwakha yamanzi, unikezelo lwamanzi ashushu kunye nemibhobho yokufudumeza yezakhiwo ezitsha zokuhlala kweli lizwe iza kusebenzisa imibhobho ye-PE emitsha, kwaye ngokusisiseko isuse imibhobho yentsimbi yesiqhelo, imibhobho yentsimbi efakwe amazimba;Ukusetyenziswa kwemibhobho yeplastiki kwimibhobho yokubonelela ngamanzi ezilalini kuya kufikelela kwi-90%.Ngo-2020, imveliso yombhobho we-PE yaseTshayina yayiziitoni ezi-4,894,400, ngokukhula konyaka-nyaka nge-7.19%.
Uhlalutyo lweprospection yemveliso yombhobho we-PE kwixesha elizayo, ngenxa yemfuno enkulu yombhobho wegesi kunye nombhobho wokuhambisa amanzi ezantsi, umbhobho we-PVC uvaliwe kumbhobho wamanzi okusela kunye nezinye izizathu, umbhobho we-PE kumbhobho weplastiki wonikezelo lwamanzi lolona khetho lungcono ngoku.Okwangoku, umyinge wokukhula wokusetyenziswa konyaka wombhobho we-PE udlule umbhobho wePVC-U, kwaye uphuhliswe kwimibhobho yeplastiki yesibini ngobukhulu emhlabeni.Kule minyaka ilishumi izayo, ukusetyenziswa kombhobho we-PE kuya kwanda, okuya kuzisa amathuba angenamkhawulo oshishino kunye nethemba elibanzi lokufaka izicelo kubaboneleli.
