Pickling Passivated Seamless Steel Yeeb Nkab Supplier-GNEE
Siv
Kev sib xyaw ua ke thiab passivation ntawm seamless steel kav thiab stainless hlau tshem tawm txhua hom roj, xeb, oxide nplai, weld me ntsis thiab lwm yam av. Tom qab kev kho mob, qhov saum npoo yuav zoo ib yam nyiaj-dawb, uas zoo heev txhim kho corrosion kuj ntawm stainless hlau thiab yog haum rau ntau hom stainless hlau qhov chaw. , daim hlau thiab lawv cov khoom siv.
Nta
Nws yog qhov yooj yim rau kev khiav lag luam, siv tau yooj yim, kev lag luam thiab siv tau. Nws kuj tseem ntxiv cov kev ua haujlwm zoo corrosion inhibitors thiab pos huab inhibitors los tiv thaiv kev xeb ntau dhau thiab hydrogen embrittlement ntawm cov hlau thiab inhibit qhov tsim ntawm cov kua qaub. Nws yog tshwj xeeb tshaj yog haum rau me me thiab complex workpieces thiab tsis haum rau paste daim ntawv thov. Nws zoo dua li cov khoom zoo sib xws ntawm kev ua lag luam.
Pickling seamless steel yeeb nkab txheej txheem ntws: degreasing --- dej ntxuav --- pickling -- dej ntxuav --- sealing agent
- Feem ntau muaj ob txoj kev pickling rau seamless steel kav (carbon steel), raws li hauv qab no:
1. sulfuric acid: dilute mus rau ib tug concentration ntawm txog 20%, tshav kub rau 60-65 degrees, thiab feem ntau ntxuav rau 20-30 feeb;
2. Hydrochloric acid: kuj dilute mus rau ib tug concentration ntawm txog 20%, thiab pickle ncaj qha rau ntawm chav tsev kub, feem ntau yog rau 20-30 feeb;
Pickled steel kav yuav tsum tau xeb-pov thawj, thiab passivation yog ib qho ntawm lawv. Nws nyob ntawm qhov zoo ntawm passivation, thiab kev xaiv tus neeg sawv cev sealing kuj tseem ceeb heev.
- Tom qab pickling (yuav tsum tau tshem tawm ntawm oxide nplai), yaug nrog dej tam sim ntawd, neutralize tam sim ntawd, thiab passivate rau kev tiv thaiv xeb.
- Scope ntawm daim ntawv thov ntawm pickling seamless steel yeeb nkab
Haum rau degreasing, xeb tshem tawm thiab phosphating kev kho mob ntawm steel qhov chaw ntawm ntau yam duab thiab cov ntaub ntawv. Nws tuaj yeem sib xyaw nrog electrostatic txau, ci xim, hmoov txau, pleev xim thiab lwm yam txheej txheem txheej.
Lub ntsiab nta ntawm pickled seamless steel kav: khoom ntim, yooj yim cia thiab tsheb thauj mus los, tag nrho cov txheej txheem ntawm cov roj tshem tawm, xeb tshem tawm, phosphating thiab passivation yuav ua kom tiav nyob rau hauv tib lub tank, txheej txheem yog yooj yim, yooj yim rau kev khiav lag luam, tsis muaj cua sov. yuav tsum tau, txuag hluav taws xob, ruaj khov zoo, kev siv tas mus li, tsis tas yuav tsum tau tawm ntau zaus, muaj kuab paug me me, tsis muaj cov khoom phom sij xws li NaNO2, NaNO3, NaF thiab Cr6+, phosphating zaj duab xis yog ntom, nruam thiab sib xws, tag nrho cov ntsuas tau ua tau raws li lub teb chaws tus qauv, thiab cov nqi kev kho mob muaj tsawg.
