Dab tsi yog Cov Txheej Txheem Rau Sintered NdFeB Magnets

Dab tsi yog cov txheej txheem rau sintered NdFeB hlau nplaum? Cov txheej txheem ntawm sintered NdFeB hlau nplaum yog npib tsib xee, tooj liab, chromium, kub, zinc, zinc, dub zinc, epoxy resin. Nws nto plating yog txawv, nws cov xim kuj txawv, thiab nws lub sij hawm cia kuj txawv. Txhua tus muaj nws qhov zoo thiab qhov tsis zoo.

1. Zinc: Qhov saum npoo zoo li silvery dawb. Nws tuaj yeem siv ua ntsev tsuag rau 12-48 teev. Nws tuaj yeem siv rau kev sib txuas nrog qee cov kua nplaum. , qhov zoo dua yog tias tus nqi qis dua.

2. Nickel: Nws zoo li cov xim ntawm cov hlau tsis muaj steel, nws yog ib qho nyuaj rau oxidized rau ntawm qhov chaw thaum sab laug hauv huab cua, thiab cov tsos zoo li zoo, gloss yog zoo, thiab cov electroplating tuaj yeem xeem dhau cov tshuaj tsuag ntsev rau { {1}} teev. Qhov tsis zoo yog tias nws tsis tuaj yeem siv rau kev sib txuas nrog qee cov kua nplaum, uas yuav ua rau cov txheej txheem poob. Txhawm rau kom ceev cov oxidation, feem ntau ntawm cov nickel-tooj ​​liab-nickel electroplating txoj hauv kev ua lag luam ua 120-200 xuab moos ntawm ntsev tsuag, tab sis tus nqi electroplating kuj yog siab heev.

3. Copper: Nws feem ntau tshwm sim hauv kev lag luam kho vajtse, thiab sintered NdFeB hlau nplaum tsis tshua siv, thiab lawv cov tsos yog daj.

4. Chromium: Kev lag luam chromium electroplating kuj tseem tsis tshua muaj, thiab nws cov nqi hluav taws xob electroplating yog siab heev, uas feem ntau tsis tsim nyog rau cov tuam txhab. Txawm li cas los xij, nws lub peev xwm los muab rot yog qhov muaj zog heev, thiab nws nyuaj rau kev cuam tshuam nrog lwm yam tshuaj. Nws yog tsuas yog siv rau hauv cov chaw uas muaj zog pH, thiab tus nqi ntawm cov khoom siv hauv tsev yog qhov tsawg, yog li ob peb tus neeg xaiv.

5. Dub zinc: raws li cov neeg siv khoom xav tau, qhov chaw ntawm cov khoom raug kho rau hauv cov xim dub. Nyob rau hauv cov txheej txheem electroplating, ib tug dub tiv thaiv zaj duab xis yog ntxiv los ntawm kev kho tshuaj nyob rau hauv lub hauv paus ntawm galvanizing. Cov yeeb yaj kiab no tseem tuaj yeem ua lub luag haujlwm tiv thaiv cov khoom. , nce lub sij hawm ntsev tsuag thiab ncua lub sij hawm oxidation. Txawm li cas los xij, nws qhov chaw yog khawb tau yooj yim thiab poob nws txoj kev tiv thaiv. Muaj tsawg tus neeg siv tam sim no, thiab feem ntau ntawm lawv tau hloov los ntawm resin. Hauv qab no peb piav qhia.

6. Kub: Qhov kev lag luam no nrov heev tam sim no. Feem ntau ntawm cov xim daj daj hauv qee lub khw muag khoom peb pom ntawm txoj kev yog kub-plated lossis tooj liab. Kub plating ua rau cov khoom zoo nkauj zoo li kub, thiab feem ntau yog siv rau hauv kev lag luam hniav nyiaj hniav kub. Peb cov khoom tseem tuaj yeem ua kub plated rau cov hniav nyiaj hniav kub sib nqus.

7. Epoxy resin: The effects of NI, ZN, epoxy resin and PARYLENE-C coating on the magnetic properties of NdFeB magnets in three solutions were comparatively studied. Polymer material>epoxy resin>NI coating>ZN txheej yog ntxiv ib txheej ntawm cov xim pleev xim rau sab nraud ntawm cov khoom tom qab nickel plating. Qhov kev lag luam no tsuas yog nyob rau hauv kev ua lag luam hauv ob xyoos dhau los, thiab nws txoj kev loj hlob sai heev. Tam sim no ntau yam khoom siv electroplating Muaj ntau tus neeg siv nws, thiab nws qhov txiaj ntsig loj yog tias nws tuaj yeem ua cov xim koj xav tau.

Yog li ntawd, cov xim sib txawv raug xaiv rau txheej ntawm sintered NdFeB hlau nplaum raws li qhov xav tau sib txawv.
