I. Tshuaj Kho Mob
Acid Pickling thiab Passivation: Acid pickling tshem tawm cov nplai oxide thiab cov roj stains, tsim cov zaj duab xis tuab. Qhov no yog lub neej ntawd txheej txheem rau cov kav dej muaj zog, uas muaj zog corrosion kuj.
Bright Annealing: Annealing yog ua nyob rau hauv ib puag ncig tiv thaiv, tshem tawm kev ntxhov siab ua haujlwm txias thiab ua rau lub ntsej muag ci thiab huv. Feem ntau siv rau cov kav dej huv.
Phosphating thiab Saponification: Ib daim ntawv phosphate hloov dua siab tshiab rau ntawm qhov chaw. Ua ke nrog saponification, nws txhim kho lubricity thiab tsim nyog rau kev kos duab txias, ncab, thiab lwm yam txheej txheem machining.
II. Kho kho tshuab
Mechanical Polishing: Sib tsoo nrog abrasive siv thiab polishing log ua tiav daim iav los yog txhuam tiav, ua rau lub siab du du thiab yooj yim tu.
Sandblasting/Shot Peening: Abrasive hais yog siv los blasting nto, tsim ib tug ntxhib, matte tiav. Kev txhaj tshuaj peening ib txhij ntxiv dag zog rau txheej txheej thiab txhim kho cov yeeb nkab kom qaug zog.
III. Electrochemical Kev Kho Mob
Electrolytic Polishing: Anodic dissolution ntawm microscopic protrusions yields ib tug ultra- du nto (Ra tsawg dua los yog sib npaug rau 0.1μm). Feem ntau siv nyob rau hauv siab - qhov chaw huv huv xws li kev kho mob thiab kev lag luam tshuaj.
IV. Kev kho tshwj xeeb / txheej
Tshuaj Polishing: Immersion nyob rau hauv ib tug tshwj xeeb acid tov ua tiav tag nrho ci tiav, haum rau complex - zoo li tus kav, thiab ntawm tus nqi qis tshaj electrolytic polishing.
Txheej / Platement: Los ntawm cov txheej txheem xws li yas txheej thiab electroplating (chromium / npib tsib xee), corrosion kuj thiab hnav tsis kam yog tiav, haum rau corrosive sab nraum zoov.
Kub-Dip Galvanizing: Zinc txheej thickness Ntau dua los yog sib npaug ntawm 85μm, ntev ntsev tsuag lub neej, qhov kev xaiv tseem ceeb rau kev txhim kho cov huab cua sab nraum zoov ntawm seamless carbon steel kav.
