Nrog rau kev txhim kho tas mus li ntawm Tuam Tshoj txoj kev lag luam, lub teb chaws vigorously txhim kho lub zog kev lag luam.Cov kav dej nyob deb ntawm cov roj thiab cov kav dej yog qhov tseem ceeb ntawm kev ruaj ntseg ntawm lub zog.Nyob rau hauv cov txheej txheem los tiv thaiv corrosion ntawm cov roj (gas) pipelines, kev kho saum npoo ntawm cov kav dej los tiv thaiv corrosion txiav txim siab txog kev pab cuam lub neej ntawm cov kav dej.Ib qho ntawm cov ntsiab lus tseem ceeb yog qhov kev pom zoo uas cov txheej txheem tiv thaiv corrosion thiab cov yeeb nkab steel tuaj yeem ua ke ruaj khov.Raws li lub koom haum tshawb fawb tshawb xyuas, lub neej ntawm cov txheej txheem tiv thaiv corrosion nyob ntawm hom txheej txheej, txheej txheej zoo thiab ib puag ncig kev tsim kho.Kev kho saum npoo ntawm cov yeeb nkab los tiv thaiv corrosion cuam tshuam rau lub neej ntawm cov txheej txheem tiv thaiv corrosion los ntawm 50%.Yog li ntawd, nws yuav tsum nruj me ntsis raws li cov txheej txheem tiv thaiv corrosion.Ua qauv raws li qhov yuav tsum tau ua ntawm cov kav dej steel, txuas ntxiv tshawb xyuas thiab sau cov ntsiab lus, thiab txuas ntxiv txhim kho txoj kev kho saum npoo ntawm cov kav hlau.

Dab tsi yuav tsum tau ua nyob rau saum npoo ntawm high-frequency anti-corrosion kauv steel yeeb nkab?

1. tu

Siv cov kuab tshuaj thiab emulsion los ntxuav cov hlau saum npoo kom tshem tau cov roj, roj, plua plav, roj nplua nyeem thiab cov organic zoo sib xws, tab sis nws tsis tuaj yeem tshem tawm xeb, nplai, flux, thiab lwm yam ntawm cov yeeb nkab steel, yog li nws tsuas yog siv los ua cov kuab tshuaj. ib tug pab txhais tau tias nyob rau hauv anti-corrosion zus tau tej cov steel yeeb nkab..

2. cuab yeej tshem tawm xeb

Qhov saum npoo ntawm cov yeeb nkab steel feem ntau yog polished los ntawm kev siv cov hlau txhuam los yog cov zoo li tshem tawm los yog tshem tawm nplai, xeb, vuam slag, thiab lwm yam.Kev tshem tawm xeb ntawm cov cuab yeej tes tuaj yeem ncav cuag qib Sa2, thiab kev tshem tawm xeb ntawm cov cuab yeej hluav taws xob tuaj yeem ncav cuag qib Sa3.Yog hais tias qhov saum npoo ntawm cov khoom siv hlau yog ua raws li cov hlau oxide nplai, qhov kev tshem tawm xeb ntawm cov cuab yeej tsis zoo tagnrho, thiab qhov tob ntawm cov thauj tog rau nkoj xav tau rau kev tsim kho corrosion tsis tuaj yeem ua tiav.

3. qob

Feem ntau, tshuaj ntxuav thiab electrolysis yog siv rau kev kho mob pickling.Anticorrosive kauv steel yeeb nkab tsuas yog kho nrog tshuaj tua kab, uas tuaj yeem tshem tawm nplai, xeb thiab txheej txheej qub, thiab qee zaum siv tau los kho dua tom qab sandblasting thiab xeb tshem tawm.Txawm hais tias kev tu tshuaj lom neeg tuaj yeem ua tiav qee qhov kev huv thiab roughness, nws cov qauv thauj tog rau nkoj yog qhov ntiav thiab nws yooj yim rau paug ib puag ncig.
