Yuav ua li cas tiv thaiv corrosion thiab xeb ntawm 16Mn seamless steel kav?
16Mn, tseem hu ua Q345, yog hom carbon hlau uas tsis tiv taus corrosion. Yog tsis muaj qhov chaw cia zoo thiab tsuas yog tso rau sab nraum zoov lossis hauv qhov chaw ntub dej thiab txias, cov pa roj carbon steel yuav xeb. Qhov no yuav tsum tau tshem tawm xeb kom ua rau nws.
Thawj txoj kev: acid ntxuav
Feem ntau, ob txoj kev, organic chemistry thiab electrolysis, yog siv rau acid pickling los daws qhov teeb meem. Rau cov yeeb nkab steel los tiv thaiv corrosion, tsuas yog cov organic chemistry acid pickling yog siv los tshem tawm oxide nplai, xeb, thiab cov txheej qub. Qee zaum, nws tuaj yeem siv los ua kev daws teeb meem tom qab sandblasting kom tshem tawm xeb. Txawm hais tias kev kho dej tshuaj muaj peev xwm ua tiav ib theem ntawm kev huv thiab roughness, nws cov kab thauj tog rau nkoj yog qhov ntiav thiab tuaj yeem ua rau muaj kuab paug rau ib puag ncig ntuj.
2: Kev ntxuav
Kev siv cov kuab tshuaj organic thiab cov kuab tshuaj los ntxuav qhov saum npoo ntawm cov hlau tuaj yeem tshem tawm cov roj, cov roj zaub, plua plav, lubricants, thiab cov organic sib txuas zoo sib xws. Txawm li cas los xij, nws tsis tuaj yeem tshem tawm xeb, oxide daim tawv nqaij, vuam flux, thiab lwm yam ntawm cov hlau, yog li nws tsuas yog siv los ua ib txoj hauv kev los tiv thaiv corrosion thiab tsim khoom.
3: Cov cuab yeej tshwj xeeb rau kev tshem tawm xeb
Cov ntawv thov tseem ceeb suav nrog kev siv cov cuab yeej tshwj xeeb xws li txhuam txhuam txhuam los txhuam thiab txhuam cov hlau, uas tuaj yeem tshem tawm xoob lossis tsa cov tawv nqaij oxide, xeb, weld nodules, thiab lwm yam. , thiab cov cuab yeej tshwj xeeb rau kev tsav tsheb tuaj yeem ua tiav qib Sa3. Yog hais tias cov hlau nto yog adhered nrog muaj zog zinc tshauv, qhov tseeb xeb tshem tawm cov txiaj ntsig ntawm cov cuab yeej tshwj xeeb tsis zoo, thiab nws tsis tuaj yeem ua tau raws li cov qauv thauj tog rau nkoj sib sib zog nqus txheej teev nyob rau hauv cov kev cai tiv thaiv corrosion ntawm fiberglass.
4: Txau (txhaj tshuaj) tshem tawm xeb
Txau (thaws) tshem tawm xeb yog ua tiav los ntawm kev siv lub tshuab hluav taws xob muaj zog los tsav cov tshuaj tsuag (pov) cov hniav kom ua haujlwm ntawm kev kub ceev, tso cai rau cov khoom hnav-resistant xws li kub, steel xuab zeb, steel pob, nplua hlau hlau ntu, thiab cov ntxhia rau tshuaj tsuag (pov) rau ntawm qhov chaw ntawm seamless steel kav nyob rau hauv centripetal quab yuam. Qhov no tsis tsuas yog tshem tawm cov xeb, hlau oxides, thiab pov tseg, tab sis kuj ua tiav qhov tsim nyog ntawm qhov chaw roughness ntawm seamless steel kav nyob rau hauv qhov muaj zog cuam tshuam thiab kev sib txhuam ntawm cov khoom hnav-resistant.
Tom qab txau (pov) xeb tshem tawm, nws tuaj yeem tsis tsuas yog nthuav tawm cov nyhuv adsorption ntawm lub raj xa dej, tab sis kuj tseem txhim kho cov nyhuv adhesion ntawm cov txheej txheem tiv thaiv corrosion rau cov khoom siv kho tshuab ntawm cov kav dej.
