Dab tsi yog qhov corrosion ntawm lub valve?
Qhov xeb ntawm lub valve feem ntau to taub qhov puas tsuaj los ntawm qhov chaw tshuaj lom neeg lossis hluav taws xob ntawm cov khoom siv hlau ntawm lub valve. Vim tias xeb tshwm sim hauv kev sib txuas 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 ntau cov khoom siv tsis yog hlau yog cov ntsiab lus tseem ceeb ntawm kev tiv thaiv. Lub cev valve (nrog rau lub hau valve) yuav siv feem ntau qhov hnyav ntawm lub valve, thiab tseem nyob rau hauv kev sib cuag nrog nruab nrab. Yog li, kev xaiv tus nqi yog feem ntau raws li cov khoom siv lub cev valve.
Kev xeb ntawm lub cev valve tsis nyob hauv ob daim ntawv, tshuaj lom neeg xeb thiab electrochemical kev txhim kho. Nws qhov kev xeb tau txiav txim siab los ntawm qhov ntsuas kub, siab, tshuaj lom neeg ntawm qhov nruab nrab thiab qhov kev tiv thaiv corrosion ntawm cov khoom hauv lub cev. Tus nqi xeb tau muab faib ua rau rau hom:
1, ua tiav cov tshuaj tiv thaiv corrosion: qhov xeb tsawg dua 0.001 hli / xyoo;
2, tsis tshua muaj kev tiv thaiv kev kub ntxhov siab: kev xeb ntawm 0.001 txog 0.01 hli / xyoo;
3, corrosion tsis kam: corrosion tus nqi ntawm 0.01 txog 0.1 hli / xyoo;
4, Shang Naishi: qhov xeb ntawm 0.1 txog 1 hli / xyoo;
5, kev xeb tsis zoo: kev xeb ntawm 1 txog 10 hli / xyoo;
6. Kev xeb tsis kam: cov xeb ntau dua 10 hli / xyoo.
Yuav ua li cas tiv thaiv valve corrosion?
Qhov ua haujlwm anticorrosion ntawm lub cev valve yog qhov tseem ceeb ntawm cov khoom siv kom raug. Kev xeb yog nplua nuj heev, tab sis tuaj yeem xaiv qhov tsim nyog, lossis tsis yooj yim, vim hais tias qhov teeb meem corrosion yog qhov nyuaj heev, xws li sulfuric acid nyob rau hauv cov ntsiab lus tsawg yog corrosive rau hlau, ua rau steel ntawm siab siab ua cov yeeb yaj kiab dhau los, xeb pov thawj; hydrogen nyob rau hauv qhov siab ntawm qhov kub siab yog xeb rau hlau yog qhov muaj zog heev, chlorine corrosion nyob rau hauv lub xeev qhuav tsis loj, tab sis thaum muaj kev noo, xeb tiv thaiv muaj zog, ntau cov ntaub ntawv tuaj yeem siv. Qhov nyuaj ntawm kev xaiv valve lub cev cov khoom tsis yog tsuas yog xav txog qhov teeb meem xeb, tab sis kuj yuav tsum xav txog yam tseem ceeb ntawm kev kub siab thiab kev tiv thaiv kub, seb qhov kev lag luam tsim nyog, seb kev yuav khoom puas yooj yim lossis tsis. Yog li nws yog qhov yuav tsum tau ceev faj.
Ua ntej, peb coj cov txheej kab kev ntsuas, xws li hauv ob sab phlu txhuas, txheej aluminium, txheej engineering plastics, lub hauv ob sab phlu ntawm cov roj hmab thiab ntau cov roj hmab hluavtaws, thiab lwm yam Yog tias cov xwm txheej nruab nrab tau tso cai, qhov no yog txoj hauv kev txuag.
Secend, dua, nyob rau hauv lub siab, qhov kub tsis dhau, nrog fluorine valve cov khoom tseem ceeb, feem ntau tuaj yeem ua kom muaj zog tiv thaiv corrosion.
Thib peb, ntxiv rau, qhov chaw sab nrauv ntawm lub pob valve tseem raug rau cov pa nkag, thiab cov khoom siv hlau dav dav muaj kev tiv thaiv xim.
