Copper valve yog ib yam khoom tseem ceeb heev rau peb, vim hais tias nws txoj kev siv yog muaj feem xyuam rau cov khoom siv thiab kev siv ntawm peb cov kav dej sib txawv, tab sis vim li cas qee zaum alkali corrosion thaum siv?
Copper li qub yog cam khwb cia los ntawm cov ntaub ntawv hlau, thiab yuav inevitably muaj ntau cov tebchaw los yog impurities thaum lub sij hawm tsim thiab ua, uas yog feem ntau ua rau cov tshuaj tsis sib xws. Uas yog hais tias, nyob rau hauv xws li ib tug teeb meem no, alkali corrosion yuav tshwm sim, uas yog, ib tug tshuaj tiv thaiv tshwm sim nyob rau hauv txoj hauj lwm ntawm cov tshuaj tsis sib xws, uas cuam tshuam rau qhov zoo ntawm lub valve. Alkali corrosion kuj tseem tuaj yeem ua rau muaj kev xeb ntau dhau ntawm aluminium castings, yog li peb cov castings yuav raug muab pov tseg. Nyob rau hauv cov ntaub ntawv no, cov chaw tsim tshuaj paus yuav nruj me ntsis tswj cov txheej txheem kom tsis txhob muaj xws li ib tug teeb meem.
Tom qab alkaline etching, peb kuj tuaj yeem siv hydrochloric acid rau kev kho mob, uas muaj txiaj ntsig zoo los tiv thaiv ib puag ncig thiab txhim kho kev ua haujlwm, thiab tuaj yeem txo cov nqi tsim khoom zoo.
