Dab tsi yog cov kev kho cov npoo ntawm cov xov ntxig?

Xov ntxig rau saum npoo kev kho yog hais txog cov txheej txheem ntawm kev tsim ib txheej txheej ntawm lub workpiece los ntawm ib txoj kev.. Tom qab kho deg, thread inserts tuaj yeem nthuav tawm qhov zoo nkauj dua, thiab corrosion kuj ntawm cov xov ntxig nws tus kheej kuj yuav raug txhim kho. Lub hom phiaj tseem ceeb tshaj yog ua kom cov xov ntxig nws tus kheej los tiv thaiv corrosion, thiaj li yuav ua rau kom muaj kev ntseeg siab thiab adaptability ntawm lub fastener. Electroplating, kub-dip galvanizing, thiab mechanical plating yog peb txoj kev siv ntau tshaj plaws rau kev kho qhov chaw ntawm cov xov inserts.

1. Electroplating
Lub electroplating ntawm xov inserts yog hais txog immersing qhov chaw ntawm cov xov inserts uas yuav tsum tau plated rau hauv ib tug tshwj xeeb aqueous tov.. Cov tshuaj aqueous yuav muaj qee cov khoom siv hlau tso. Ua li no, tom qab qhov tam sim no dhau los ntawm cov tshuaj aqueous, cov tshuaj hlau nyob rau hauv cov tshuaj precipitate thiab ua raws li cov xov inserts. ntawm qhov immersed feem ntawm lub firmware. Cov electroplating ntawm fasteners feem ntau suav nrog zinc plating, tooj liab, npib tsib xee, chromium, tooj liab-nickel alloy, lwm. Qee zaum npau dub (xiav), phosphating, lwm. kuj suav nrog.

2. Kub dip galvanizing
Kub-dip galvanizing ntawm fasteners yog rau immerse carbon steel xov inserts rau hauv ib tug molten zinc plating da dej nrog ib tug kub ntawm txog 510 ° C., yog li ntawd cov hlau-zinc alloy nyob rau saum npoo ntawm fastener yuav hloov mus rau passivated zinc. Kom tau txais cov nyhuv kho qhov chaw (zoo ib yam li kub dip aluminium plating)

3. Mechanical plating
Mechanical plating ntawm xov inserts hais txog kev siv lub cev thiab tshuaj txhais tau tias cuam tshuam rau saum npoo ntawm cov xov inserts nrog coated hlau hmoov, yog li ntawd cov hlau coated ua ib txheej rau ntawm qhov chaw ntawm lub fastener los ntawm txias welding kom ua tiav cov nyhuv kho deg. Mechanical plating ntawm fasteners yog tsuas yog haum rau spare qhov chaw xws li screws, txiv ntseej thiab washers.

Txhawm rau txiav txim qhov zoo ntawm xov ntxig rau saum npoo kho, nws yog qhov tseem ceeb los xyuas seb puas muaj peev xwm tiv thaiv corrosion ntawm cov xov ntxig tau zoo thiab seb qhov nce raws li qhov xav tau.. Txoj kev tshuaj xyuas yog simulate qhov chaw ua haujlwm ntawm cov khoom, teem caij xeem, thiab ua cov kev ntsuam xyuas corrosion ntawm nws. Qhov thib ob kauj ruam yog los xyuas qhov tsos.
