Cov txheej txheem passivation ntawm stainless hlau welded yeeb nkab

Tus txheej txheem pickling ntawm stainless hlau welded yeeb nkab yog kom tshem tawm cov yeeb nkab vuam thiab lwm yam stains zoo dua, nws yuav tshwm sim dawb thiab ua kom muaj kev siv dawb thiab lub neej ntawm cov yeeb nkab steel.

Yog li dab tsi yog tus txheej txheem pickling ntawm stainless hlau welded yeeb nkab? Cov kws tshaj lij los ntawm Hangao Tech (Seko Machinery) qhia koj.

1. Kev npaj: teeb tsa cov kev daws teeb meem acid raws li cov nyiaj yuav tsum tau ua. Cov kev daws teeb meem yog npaj los ntawm cov qauv ntawm nitric acid thiab hydrofluoric acid; Npaj cov kua qaub-resistant passivation tank thiab txhuam txhuam.

2. Tshuaj lom neeg pickling: tshem tawm cov raj txij hauv cov tshuaj pickling yam tsis tau tumbling thiab txav mus ua tiav cov nyhuv ua haujlwm; Yog tias nws ntsib cov khoom muaj zog stains, siv lub hlau xaim txhuam kom tshem nws.

3. Yau: Tom qab pickling, yaug nrog txias thiab kub dej hloov thiab kom huv si rau lub sijhawm tsis pub tsawg tshaj 20 feeb.

4. Passivation: Thov cov neeg sawv cev passivating rau lub workpiece uas tau raug pickled thiab sawv tseem yog rau lub sijhawm uas passivation zaj duab xis yog cov adsorbed rau saum npoo.
