PE tubtau dav siv hauv peb lub neej thiab ua lub luag haujlwm.Yuav kom siv tau zoo dua thiab tswj cov khoom no, nws yog ib qho tsim nyog yuav tsum nkag siab txog kev paub txog PE yeeb nkab corrosion.
Tshuaj tua kab mob: Cov tshuaj tua kab mob ntawm cov yeeb nkab PE yog tshwm sim los ntawm kev tawm tsam ncaj qha ntawm cov tshuaj dawb huv ntawm cov hlau zoo li thiab cov tsis-electrolyte.Ntawd yog, tom qab cov hlau nyob rau hauv kev sib cuag ncaj qha nrog nruab nrab, cov txheej txheem ablation ntawm cov hlau ions tshwm sim tsis sib xws ntawm cov hlau nto, thiab qhov ablation ceev kuj qeeb.
Electrochemical corrosion: Kev puas tsuaj los ntawm electrochemical corrosion ntawm cov hlau nto thiab electrochemical kev ua ntawm ionic conductive nruab nrab ntawm cov yeeb nkab PE yog tias cov txheej txheem hlau electrolysis tshwm sim hauv thawj lub roj teeb uas muaj hlau thiab electrolyte.Txhua qhov chaw, cov lus teb corrosion raws li cov txheej txheem electrochemical muaj tsawg kawg yog ib qho lus teb anodic thiab ib qho cathodic teb txuas los ntawm kev khiav ntawm electrons los ntawm cov hlau thiab cov ndlwg ntawm ions hauv nruab nrab.
Cov kab mob Erosion: Cov txheej txheem ntawm cov kab mob yaig ntawm cov hlau yog qhov nyuaj, tab sis hauv qee cov av, peb hom kab mob tau koom nrog cov txheej txheem yaig: sulfate-txo cov kab mob, cov kab mob sulfur-oxidizing, thiab cov kab mob hlau.
PE yeeb nkab yog cov khoom siv polyethylene yas yeeb nkab, yog vim li cas tib neeg xaiv cov yeeb nkab no yog nws cov kev ua tau zoo thiab cov nqi sib xws.Kev tso cov kav dej PE yog qhov yooj yim thiab ceev, nrog kev puas tsuaj tsawg thiab cov nqi tu.Tsuav qhov sib koom ua ke zoo, nws tuaj yeem tiv taus axial loads yam tsis muaj to.
Yog li ntawd, cov ntsiab lus thauj tog rau nkoj thiab cov piers ntawm cov pob qij txha thiab khoov tsis tas yuav tsum tau tso, txo cov nqi.Polyethylene (PE) cov khoom siv dav siv hauv kev tsim cov yeeb nkab dej vim nws lub zog siab, corrosion kuj thiab tsis muaj tshuaj lom.Nws yuav tsis xeb thiab yog cov khoom zoo tshaj plaws los hloov cov kav dej zoo tib yam hlau.
Nyob rau tib lub sijhawm, vim nws lub teeb yuag, zoo toughness, zoo cuam tshuam tsis kam, kuj pheej yig tus nqi thiab zoo kub tsis kam, PE kav yog tam sim no dav siv nyob rau hauv lub nroog kev tsim kho, vaj tse, thiab factories.PE yeeb nkab fittings yog ecological thiab ib puag ncig tus phooj ywg, thiab tsis muaj tshuaj lom additives ntxiv thaum lub sij hawm tsim khoom.Cov qauv ntawm cov phab ntsa sab hauv ntawm lub raj xa dej yog du, tsis muaj scaling thiab kab mob, thiab kev tsim khoom, kev sib txuas thiab kev tsim kho thev naus laus zis tau paub tab.Raws li nws lub cev thiab txhua yam khoom, nws txais kev sib txuas kub yaj los yog flange kev txhawb nqa kev sib txuas, uas muaj qhov toughness siab, txhim khu kev qha kev sib txuas, kev tsim kho yooj yim, kev tiv thaiv siab coefficient thiab qis to.
