Anti-corrosion ntawmBrass Pob Valvelub cev yog tsuas yog nyob ntawm qhov raug xaiv ntawm cov ntaub ntawv.Txawm hais tias muaj ntau cov ntaub ntawv los tiv thaiv corrosion, nws tsis yooj yim los xaiv qhov zoo, vim tias qhov teeb meem ntawm corrosion yog qhov nyuaj heev.Piv txwv li, sulfuric acid yog heev corrosive rau hlau thaum lub concentration yog tsawg, thiab thaum lub concentration siab, cov hlau yog tsim.Passivation zaj duab xis tuaj yeem tiv thaiv corrosion;hydrogen tsuas pom muaj zog corrosiveness rau hlau nyob rau hauv qhov kub thiab txias.Kev ua haujlwm corrosion ntawm cov tshuaj chlorine tsis zoo thaum nws nyob hauv lub xeev qhuav, tab sis nws yog corrosive heev thaum muaj cov av noo, thiab ntau cov ntaub ntawv siv tsis tau..Qhov nyuaj ntawm kev xaiv valve lub cev cov ntaub ntawv nyob rau hauv tsis yog tsuas yog xav txog tej teeb meem corrosion, tab sis kuj tseem ceeb xws li siab tsis kam thiab kub tsis kam, seb nws yog economic tsim nyog, thiab seb nws yog ib qho yooj yim mus yuav.Yog li ntawd nws yuav tsum tau attentive.

Qhov thib ob yog siv cov txheej txheem hauv ob sab phlu, xws li hauv ob sab phlu, hauv ob sab phlu aluminium, hauv ob sab phlu engineering plastics, hauv ob sab phlu ntuj, thiab ntau yam hluavtaws roj hmab.Yog tias cov xwm txheej hauv xov xwm tso cai, qhov no yog txoj hauv kev lag luam.

Ntxiv dua thiab, nyob rau hauv cov ntaub ntawv ntawm tsis tshua muaj siab thiab kub, siv tsis yog hlau raws li lub valve lub cev khoom feem ntau yuav ua tau zoo heev los tiv thaiv corrosion.

Tsis tas li ntawd, sab nrauv ntawm lub valve lub cev kuj corroded los ntawm cov cua, thiab feem ntau steel cov ntaub ntawv yog tiv thaiv los ntawm painting.

Qhov corrosion ntawm lub valve feem ntau yog to taub raws li kev puas tsuaj rau cov khoom siv hlau ntawm lub valve nyob rau hauv qhov kev txiav txim ntawm ib puag ncig chemical lossis electrochemical.Txij li thaum "corrosion" tshwm sim tshwm sim nyob rau hauv kev sib cuam tshuam ntawm cov hlau thiab ib puag ncig ib puag ncig, yuav ua li cas cais cov hlau los ntawm ib puag ncig ib puag ncig lossis siv cov khoom siv tsis yog xim hlau ntau dua yog qhov tseem ceeb ntawm kev tiv thaiv corrosion.

Lub valve lub cev (xws li lub kaus mom) ntawm lub valve tuav feem ntau ntawm qhov hnyav ntawm lub valve thiab yog nyob rau hauv kev sib cuag nrog nruab nrab.Yog li ntawd, kev xaiv ntawm lub valve feem ntau yog raws li cov khoom ntawm lub valve lub cev.

Qhov corrosion ntawm lub valve lub cev tsis muaj dab tsi ntau tshaj li ob hom, uas yog tshuaj corrosion thiab electrochemical corrosion.Nws tus nqi corrosion nyob ntawm qhov kub, siab, tshuaj lom neeg ntawm nruab nrab thiab corrosion kuj ntawm lub valve lub cev khoom.Tus nqi corrosion tuaj yeem muab faib ua rau qib:

1. Ua tiav corrosion tsis kam: tus nqi corrosion yog tsawg dua 0.001 hli / xyoo;

2. Kev tiv thaiv corrosion heev: tus nqi corrosion yog 0.001 txog 0.01 hli / xyoo;

3. Corrosion kuj: tus nqi corrosion yog 0.01 txog 0.1 hli / xyoo;

4. Tseem corrosion resistant: tus nqi corrosion yog 0.1 txog 1.0 hli / xyoo;

5. Tsis zoo corrosion kuj: tus nqi corrosion yog 1.0 mus rau 10 hli / xyoo;

6. Tsis muaj corrosion resistant: tus nqi corrosion yog ntau tshaj 10 hli / xyoo.
