Kev Tiv Thaiv & Kev Kho Mob ntawm Kev Xeb ntawm Lub Qhov Rooj Npauj Npaim

Dab tsi yog corrosion ntawmnpauj npaim li qub?

Kev xeb ntawm cov npauj npaim valve feem ntau yog nkag siab tias yog kev puas tsuaj ntawm cov khoom siv hlau ntawm lub valve nyob rau hauv qhov kev ua ntawm tshuaj lom neeg lossis electrochemical ib puag ncig. Txij li thaum qhov tshwm sim ntawm "xeb" tshwm sim hauv kev sib cuam tshuam ntawm hlau thiab ib puag ncig ib puag ncig, yuav ua li cas cais cov hlau ntawm ib puag ncig ib puag ncig lossis siv ntau cov khoom siv tsis yog hlau yog qhov tseem ceeb ntawm kev tiv thaiv xeb. Lub cev ntawm lubnpauj npaim valve(suav nrog lub hau valve) nyob feem ntau ntawm qhov hnyav ntawm lub valve thiab feem ntau sib cuag nrog cov khoom nruab nrab, yog li lub npauj npaim valve feem ntau xaiv los ntawm cov khoom siv lub cev.

Tsuas muaj ob hom kev xeb ntawm lub cev valve xwbnpauj npaim li qub, uas yog kev xeb tshuaj lom neeg thiab kev xeb hluav taws xob. Nws qhov kev xeb yog txiav txim siab los ntawm qhov kub thiab txias, siab, cov khoom siv tshuaj lom neeg ntawm cov khoom nruab nrab, thiab qhov kev tiv thaiv kev xeb ntawm cov khoom siv lub cev valve. Qhov kev xeb tuaj yeem faib ua rau theem:

1. Kev tiv thaiv xeb tag nrho: tus nqi xeb tsawg dua 0.001 hli / xyoo;

2. Kev tiv thaiv xeb heev: tus nqi xeb 0.001-0.01 hli / xyoo;

3. Kev tiv thaiv xeb: tus nqi xeb 0.01-0.1 hli / xyoo;

4. Kev tiv thaiv xeb siab: tus nqi xeb 0.1-1.0 hli / xyoo;

5. Kev tiv thaiv xeb tsis zoo: tus nqi xeb 1.0-10 hli / xyoo;

6. Tsis kam xeb: tus nqi xeb ntau dua 10 hli / xyoo.

Yuav ua li cas kom tsis txhob muaj corrosion ntawmnpauj npaim li qub?

Qhov tiv thaiv xeb ntawm lub cev valve ntawm lub npauj npaim valve feem ntau yog vim xaiv cov ntaub ntawv kom raug. Txawm hais tias cov ntaub ntawv hais txog kev tiv thaiv xeb muaj ntau heev, nws tsis yooj yim xaiv qhov yog, vim tias qhov teeb meem ntawm kev xeb yog qhov nyuaj heev, piv txwv li, sulfuric acid yog corrosive heev rau hlau thaum qhov concentration qis, thiab thaum qhov concentration siab, nws ua rau cov hlau tsim cov zaj duab xis passivation, uas tuaj yeem tiv thaiv xeb; Hydrogen tsuas yog pom tias yog corrosive heev rau hlau ntawm qhov kub thiab siab, thiab kev ua haujlwm corrosion ntawm chlorine roj tsis loj thaum nws qhuav, tab sis kev ua haujlwm corrosion yog muaj zog heev thaum muaj qee qhov av noo, thiab ntau yam khoom siv tsis tuaj yeem siv. Qhov nyuaj ntawm kev xaiv cov ntaub ntawv lub cev valve yog tias peb tsis tuaj yeem tsuas yog xav txog cov teeb meem corrosion, tab sis kuj xav txog cov yam xws li kev kub siab thiab kev tiv thaiv kub, seb nws puas tsim nyog rau kev lag luam, thiab seb nws puas yooj yim yuav. Yog li koj yuav tsum tau ua tib zoo.

1. Qhov thib ob yog siv cov txheej txheem sab hauv, xws li cov hlau txhuas, txhuas, cov yas engineering, roj hmab ntuj thiab ntau yam roj hmab hluavtaws. Yog tias qhov xwm txheej nruab nrab tso cai, qhov no yog txoj hauv kev txuag.

2. Qhov thib peb, thaum lub siab thiab kub tsis siab, cov khoom siv tseem ceeb ntawm lub valve uas muaj fluorine feem ntau tuaj yeem ua tau zoo heev hauv kev tiv thaiv kev xeb.

3. Tsis tas li ntawd xwb, sab nraud ntawm lub cev valve kuj raug cua corroded, thiab cov khoom siv hlau ductile feem ntau yog tiv thaiv los ntawm nickel plating.

TWS yuav sai sai no tso tawm cov khoom tiv thaiv xeb tshiab, uas suav nrog ntau yam kev daws teeb meem valve xws linpauj npaim li qub, lub qhov rooj vag, xyuas cov li qubthiab lub pob valve, thiab lwm yamCov khoom no siv cov thev naus laus zis tiv thaiv kev xeb thiab cov txheej txheem kho khoom siv tshwj xeeb los tswj kev ua haujlwm zoo heev thiab kev ruaj khov ua haujlwm nyob rau hauv cov xwm txheej ua haujlwm hnyav. Peb cog lus tias yuav muab cov khoom siv valve rau cov neeg siv khoom, ua kom lub neej ua haujlwm ntawm cov khoom siv ntev dua, txo cov nqi txij nkawm thoob plaws lub neej.ncua sijhawmlub voj voog, thiab pab cov neeg siv khoom txiav txim siab yuav khoom muaj nqis dua.
