Imibhobho ye-PEzisetyenziswa kakhulu ebomini bethu kwaye zidlala indima ethile.Ukuze kusetyenziswe kakuhle kwaye kugcinwe le mveliso, kubaluleke kakhulu ukuqonda ulwazi olufanelekileyo lokubola kombhobho we-PE.
Ukuhlaselwa kweekhemikhali: Ukuhlaselwa kweekhemikhali zombhobho we-PE kubangelwa ukuhlaselwa ngokuthe ngqo kwesenzo sekhemikhali ecocekileyo phakathi kokubonakala kwesinyithi kunye ne-non-electrolyte.Oko kukuthi, emva kokuba isinyithi sinxibelelana ngokuthe ngqo ne-medium, inkqubo yokukhutshwa kwee-ion zetsimbi iyenzeka ngokufanayo kumphezulu wesinyithi, kwaye isantya sokukhutshwa sihamba kancinci.
I-Electrochemical corrosion: Umonakalo owenziwe kukuhlwa kwe-electrochemical kumphezulu wesinyithi kunye nesenzo se-electrochemical ye-ionic conductive medium yombhobho we-PE kukuba inkqubo ye-metal electrolysis yenzeke kwibhetri yokuqala eyenziwe yintsimbi kunye ne-electrolyte.Naphi na, impendulo ye-corrosion ngokwe-electrochemical mechanism iquka ubuncinane impendulo ye-anodic kunye nempendulo enye ye-cathodic edityaniswe nokuhamba kwee-electron ngesinyithi kunye nokuhamba kwee-ion phakathi.
Ukhukuliseko lweBhaktheriya: Indlela yokutshatyalaliswa kwebhaktheriya yentsimbi inzima, kodwa kweminye imihlaba, iintlobo ezintathu zebhaktheriya zibandakanyeka kwinkqubo yokhukuliseko: iibhaktheriya ezinciphisa i-sulfate, ibhaktheriya ene-sulfur-oxidizing, kunye neebhaktheriya zentsimbi.
Ipayipi ye-PE yimveliso yepayipi yeplastiki ye-polyethylene, isizathu sokuba abantu bakhethe le mbhobho kukusebenza kwayo okuphezulu kunye nexabiso elihambelanayo.Ukubekwa kwemibhobho ye-PE kulula kwaye kuyakhawuleza, kunye nomonakalo ophantsi kunye neendleko zokugcinwa.Ngethuba nje umdibaniselwano ulungile, unokumelana nemithwalo ye-axial ngaphandle kokuvuza.
Ngenxa yoko, amanqaku e-anchor kunye neepiers kwiindawo ezidibeneyo kunye nokugoba akufuneki ukubeka, ukunciphisa iindleko.Izinto zePolyethylene (PE) zisetyenziswa ngokubanzi kwintsimi yokwenziwa kombhobho wonikezelo lwamanzi ngenxa yamandla ayo aphezulu, ukumelana nokugqwala kunye nokungabi yingozi.Ayiyi kugqwala kwaye iyimveliso efanelekileyo yokutshintsha imibhobho yentsimbi eqhelekileyo.
Kwangaxeshanye, ngenxa yobunzima bayo obulula, ukuqina okuhle, ukumelana nempembelelo entle, ixabiso eliphantsi kunye nokumelana nobushushu obuphantsi, imibhobho ye-PE ngoku isetyenziswa ngokubanzi kulwakhiwo lukamasipala, izindlu nomhlaba, kunye neefektri.Izixhobo zombhobho we-PE zihambelana nendalo kunye nokusingqongileyo, kwaye akukho zongezelelo ezinobuthi zongezwa ngexesha lenkqubo yokuvelisa.Isakhiwo sodonga lwangaphakathi lombhobho luhamba kakuhle, alunamlinganiselo kunye neebhaktheriya, kwaye imveliso, ukudibanisa kunye nobuchwepheshe bokwakha bukhulile.Ngokweempawu zayo zomzimba kunye noomatshini, ithatha uxhulumaniso olushushu lwe-melt okanye uxhulumaniso lwenkxaso ye-flange, enobunzima obuphezulu, uxhulumaniso oluthembekileyo, ukwakhiwa okufanelekileyo, i-coefficient yokukhusela ephezulu kunye nesantya esiphantsi sokuvuza.
