Corrosion yog ib qho tseem ceeb uas ua raunpauj npaim valve kev puas tsuaj. Hauvnpauj npaim valve kev tiv thaiv,npauj npaim valve Kev tiv thaiv corrosion yog ib qho teeb meem tseem ceeb uas yuav tsum tau xav txog. Rau hlaunpauj npaim valves, kev kho deg txheej yog txoj kev tiv thaiv tus nqi zoo tshaj plaws.
Lub luag haujlwm ntawmhlaunpauj npaim valve txheej txheej
01. Kev tiv thaiv
Tom qab cov hlau nto yog coated nrog cov xim, cov hlau nto kuj raug cais tawm ntawm ib puag ncig. Qhov kev tiv thaiv no tuaj yeem hu ua shielding effect. Tab sis nws yuav tsum tau taw qhia tias ib txheej nyias ntawm cov xim tsis tuaj yeem ua lub luag haujlwm tiv thaiv. Vim hais tias lub siab polymer muaj qee qhov huab cua permeability, thaum lub txheej yog nyias nyias, nws cov qauv pores tso cai rau cov molecules ntawm dej thiab oxygen mus dawb. Mos-sealednpauj npaim valves muaj cov kev cai nruj ntawm cov tuab ntawm epoxy txheej ntawm qhov chaw. Nws tuaj yeem pom tau tias rau ntau txheej txheej tus nqi yog ntau dua li cov hlau tsis muaj coated. Txhawm rau txhim kho lub impermeability ntawm cov txheej txheej, cov txheej tiv thaiv corrosion yuav tsum siv cov yeeb yaj kiab tsim cov khoom siv nrog cov cua permeability tsawg thiab cov khoom muab tub lim nrog cov khoom thaiv loj, thiab tib lub sijhawm, cov txheej txheej txheej yuav tsum tau nce ntxiv. kom cov txheej tuaj yeem ncav cuag ib qho tuab thiab tuab thiab tsis ntxeem tau.
02. Corrosion inhibition
Los ntawm reacting lub sab hauv Cheebtsam ntawm txheej nrog cov hlau, cov hlau nto yog passivated los yog ib tug tiv thaiv khoom yog generated los txhim kho cov kev tiv thaiv nyhuv ntawm txheej.npauj npaim valvessiv rau cov kev cai tshwj xeeb yuav tsum tau them sai sai rau qhov muaj pes tsawg leeg ntawm cov xim kom tsis txhob muaj kev phom sij loj. Tsis tas li ntawd, cov cam khwb cia hlaunpauj npaim valve siv nyob rau hauv cov roj pipeline, cov khoom degradation generated nyob rau hauv qhov kev txiav txim ntawm qee cov roj thiab kev ua kom qhuav ntawm cov hlau soaps tuaj yeem ua lub luag haujlwm ntawm cov organic corrosion inhibitors.
03. Kev tiv thaiv hluav taws xob
Electrochemical corrosion nyob rau hauv zaj duab xis tshwm sim thaum lub dielectric permeable txheej los rau hauv kev sib cuag nrog cov hlau nto. Siv cov hlau uas muaj kev ua haujlwm siab dua li cov hlau ua cov khoom ntim hauv cov txheej, xws li zinc. Nws yuav ua si lub luag hauj lwm tiv thaiv ntawm sacrificial anode, thiab cov khoom siv corrosion ntawm zinc yog cov zinc chloride thiab zinc carbonate, uas yuav ua rau cov kab sib txawv ntawm daim nyias nyias thiab ua rau daim nyias nyias nyias, uas zoo heev txo cov corrosion thiab ua rau lub neej kev pab cuam ntev.npauj npaim valve.
Feem ntau siv coatings rau hlaunpauj npaim valves
01.npauj npaim valve lub cev epoxy resin txheej
Nws muaj cov yam ntxwv hauv qab no:
Corrosion kuj
Epoxy-coated steel bars muaj kev tiv thaiv corrosion zoo, thiab lub zog ntawm kev sib koom tes nrog pob zeb yog txo qis. Nws yog qhov tsim nyog rau kev lag luam hauv thaj chaw ntub dej lossis kev tawm tsam hnyav.
muaj zog adhesion
Lub xub ntiag ntawm polar hydroxyl thiab ether bonds muaj nyob rau hauv cov saw molecular ntawm epoxy resins ua rau nws nplaum heev rau ntau yam khoom. Epoxy resin muaj tsawg shrinkage thaum kho, thiab cov kev ntxhov siab sab hauv tsim yog me me, thiab kev tiv thaiv txheej txheej tsis yooj yim rau poob thiab poob.
Cov khoom hluav taws xob
Lub kho epoxy resin system yog ib qho zoo heev insulating khoom nrog siab dielectric zog, nto to resistance thiab arc kuj.
Pwm resistant
Kho epoxy systems yog resistant rau feem ntau pwm thiab yuav siv tau nyob rau hauv hnyav tropical tej yam kev mob.
02 ib.npauj npaim valve phaj nylon phaj khoom
Cov ntaub ntawv nylon yog cov tsis tshua muaj corrosion-resistant thiab tau ntse siv nyob rau hauv ntau daim ntawv thov xws li dej, av nkos, zaub mov, thiab desalination.
pw sab nraum zoov
Cov txheej txheej nylon tuaj yeem dhau qhov kev ntsuam xyuas ntsev tsuag, thiab cov txheej txheem tsis tau tev tawm tom qab muab tso rau hauv dej hiav txwv rau ntau tshaj 25 xyoo, yog li tsis muaj corrosion rau hlau qhov chaw.
abrasion tsis kam
Nws muaj kev puas tsuaj zoo heev.
cuam tshuam tsis kam
Tsis muaj cov cim ntawm tev nyob rau hauv muaj zog cuam tshuam.
