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 chaw cia khoom zoo thiab tsuas yog muab tso sab nraum zoov lossis hauv qhov chaw noo thiab thiab ntuj txias ib puag ncig, cov hlau hlau yuav xeb. Qhov no yuav tsum muaj xeb tshem tawm kom tau ua rau nws.
Thawj txoj kev: acid ntxuav
Feem ntau, ob txoj kev, cov organic chemis thiab electrolysis, siv rau cov kua qaub pickling los daws cov teeb meem. Rau cov yeeb nkab steel-corrosion, tsuas yog organic chemistry acid pickling yog siv los tshem tawm oxide nplai, xeb, thiab qub txheej. Qee zaum, nws tuaj yeem siv los ua kev daws teeb meem tom qab sandblasting kom tshem tawm xeb. Txawm hais tias kev kho tshuaj dej tuaj yeem ua tiav qee qib kev huv thiab ntxhib cov kab yog ntiav thiab ua rau ib puag ncig pa hluav taws xob ib puag ncig rau lub ntuj.
2: ntxuav
Kev siv ntawm cov kuab tshuaj organic thiab cov kuab tshuaj los ntxuav cov roj av, cov roj zaub, plua plav, cov roj av sib xyaw. Txawm li cas los xij, nws tsis tuaj yeem tshem tawm cov xeb, oxide, vuam flux, thiab lwm yam.
3: Cov cuab yeej tshwj xeeb rau kev tshem tawm xeb
Cov ntawv thov tseem ceeb suav nrog cov cuab yeej tshwj xeeb xws li txhuam cov tawv nqaij, xeb, xeb, xeb, xeb, xeb, xeb. , thiab cov cuab yeej tshwj xeeb rau kev tsav tsheb muaj peev xwm ua tiav Sa3 qib. Yog hais tias cov hlau nto yog adhered nrog muaj zog zinc tshauv, qhov tseeb xeb tawm ntawm cov khoom tshwj xeeb sib sib zog nqus txheej hauv kev tiv thaiv corrosion ntawm fibergion
4: Tsuag (Tsuag tshem tawm
Txau (ntuav) Rust tshem tawm yog tiav los ntawm kev siv lub zog hluav taws xob kom tsav tsheb kom tsav tsheb, steel xuab zeb, cov pob zeb steel, cov hlau sib tw, Thiab cov zaub mov kom tsuag (ntuav) rau saum npoo ntawm seamless steel kav hauv qab centripal. Qhov no tsis tsuas yog tshem tawm tag nrho tshem tawm cov xeb, thiab khib nyiab, tab sis kuj tseem ua tiav cov khoom lag luam uas tsim nyog nyob rau hauv cov khoom muaj zog thiab kev sib txhuam ntawm cov khoom siv-resistant cov ntaub ntawv.
Tom qab txau (ntuav) Rust tshem tawm, nws tsis tuaj yeem nthuav tawm cov nyhuv kos duab ntawm lub raj ntawm cov khoom siv tshuaj tiv thaiv corrosion rau cov cuab yeej siv tshuab hluav taws xob.
