I. Tshuaj Kho Mob
1. Pickling thiab Passivation: Pickling tshem tawm nto oxide nplai, roj, thiab weld spatter, tsim ib tug tuab passivation zaj duab xis. Qhov no yog cov txheej txheem ua ntej rau cov kav dej, uas ua rau cov nyiaj matte -dawb tiav nrog muaj zog corrosion kuj.
2. Bright Annealing: Annealing yog ua nyob rau hauv lub tshuab nqus tsev los yog ib qho chaw tiv thaiv kom tshem tawm cov kev ntxhov siab ua hauj lwm txias, ua rau lub siab nto tiav (Ra tsawg dua los yog sib npaug rau 0.4μm). Qhov no feem ntau yog siv rau siab - cov pa roj purity thiab cov kav dej huv huv.
3. Phosphating thiab Saponification: Lub phosphate hloov dua siab tshiab zaj duab xis yog tsim nyob rau saum npoo, ua raws li saponification, ho txhim kho lubricity thiab ua rau nws haum rau txias txias, stretching, thiab lwm yam machining txheej txheem.
II. Kho kho tshuab
1. Mechanical Polishing: Siv abrasive siv thiab polishing log, polishing yog ua nyob rau hauv ntxhib, nruab nrab, thiab nplua theem, ua tiav daim iav tiav thiab txhuam tiav. Qhov nto tiav (Ra) yog kwv yees li 0.4-0.8μm, thiab nws yooj yim los ntxuav thiab tswj.
2. Sandblasting/Shot peening: Nto blasting nrog quartz xuab zeb, alumina, thiab lwm yam., tsim ib qho ntxhib, matte tiav. Kev txhaj tshuaj peening siv spherical pellets ib txhij ntxiv dag zog rau saum npoo thiab txhim kho cov yeeb nkab kom qaug zog.
III. Electrochemical Kev Kho Mob
1. Electrolytic Polishing: Anodicly dissolves microscopic protrusions rau ntawm qhov chaw, ua rau ib tug ultra- du nto (Ra tsawg dua los yog sib npaug rau 0.1-}0.2μm), txhim kho corrosion kuj. Dav siv nyob rau hauv high-cleanliness ib puag ncig xws li kev kho mob thiab tshuaj industries.
IV. Kev kho tshwj xeeb / txheej
1. Tshuaj Polishing: Immersion nyob rau hauv tshwj xeeb acid daws ua tiav tag nrho brightness. Tsim nyog rau cov kav dej complex - zoo li tus, thiab ntawm tus nqi qis dua li electrolytic polishing.
2. Txheej: Los ntawm txoj kev xws li txheej yas, txau, thiab electroplating nrog chromium / npib tsib xee, corrosion kuj, hnav tsis kam, thiab xim yog tiav, haum rau sab nraum zoov thiab siab - hnav.
3. Kub-dip galvanizing: Nrog zinc txheej thickness Ntau dua los yog sib npaug ntawm 85μm thiab cov ntsev tsuag lub neej ntev tshaj 500 teev, nws yog qhov kev xaiv tseem ceeb rau kev txhim kho huab cua sab nraum zoov ntawm carbon steel seamless kav.
