Taw qhia rau Cov yam ntxwv ntawm Electroplated Coatings On Threaded Fasteners

1. Electroplated txheej thickness ntawm threadedfasteners

Nyob rau hauv electroplating ua ntawm threaded fasteners, txawm tias siv yob plating los yog dai plating txheej txheem, cov txheej thickness tau rau txhua fastener nyob rau hauv ib tug batch ntawm cov khoom sib txawv, thiab txawm lub txheej tis ntawm tib lub fastener yog unevenly. Cov txheej tuab ntawm sab saum toj ntawm cov hniav threaded yog thicker dua li ntawm nruab nrab txoj kab uas hla thiab hauv qab ntawm cov hniav, thiab txheej thickness ntawm ob kawg ntawm cov ntsia hlau thiab ntsia liaj qhov rooj yog thicker tshaj li nyob rau hauv nruab nrab, thiab ua ntau tseem ceeb nrog nce. ntev mus rau txoj kab uas hla. Tib yam siv rau txiv ntseej. Vim cov nyhuv shielding thaum lub sij hawm cov txiv ntoo electroplating ua, cov txheej txheej plating ntawm cov xov sab hauv yog nyias nyias, tsuas yog cov txheej plating ntawm thawj cov hniav ntawm ob hnub tuab dua li txheej plating ntawm nruab nrab, uas yog sib npaug rau cov tuab ntawm lub hexagonal wrench nto.

2. Yuav ua li cas piav qhia lub plating txheej thickness ntawm ib batch ntawm threaded fasteners

Vim yog qhov tsis sib xws ntawm plating thickness ntawm threaded fasteners, tus qauv hais plaub lub ntsiab lus ntawm plating thickness, uas yog "nominal plating thickness", "batch nruab nrab thickness", "loj thickness", thiab "zoo plating thickness". Lub nominal txheej thickness yog hais txog lub nominal txheej thickness ntawm threaded fasteners thiab tsis tuaj yeem sawv cev rau qhov tseeb txheej thickness. Qhov tseeb txheej thickness ntawm threaded fasteners yog piav raws li "zoo txheej thickness". Qhov zoo txheej thickness muaj xws li ob yam: batch nruab nrab thickness thiab hauv zos thickness.

Plating thickness ntawm threaded fasteners tsis tuaj yeem sawv cev los ntawm plating thickness ntawm ib feem. Txawm hais tias cov threaded fasteners tau ua tiav los ntawm kev siv dai plating lossis dov plating txheej txheem, txhua qhov hauv tib pawg tsis tuaj yeem ua tiav tib lub plating thickness, tab sis qhov kev hloov ntawm thickness ua raws li ib txwm faib. Peb xav hais tias lub plating thickness yog uniformly faib rau ntawm qhov chaw ntawm lub batch ntawm qhov chaw los xam qhov nruab nrab plating thickness, uas qhia lub tswvyim ntawm "batch nruab nrab thickness", qhov nruab nrab thickness ntawm lub batch yuav siv tau los piav txog cov txheej thickness ntawm tag nrho batch ntawm threaded fasteners. Qhov nruab nrab batch thickness nyob rau hauv Standard Table 1 yog sawv cev raws li ib tug ntau yam. Qhov tsawg kawg nkaus batch nruab nrab tuab yog qhov yuav tsum tau ua kom muaj kev tiv thaiv corrosion ntawm threaded fasteners, thaum lub siab tshaj plaws batch nruab nrab thickness yog los xyuas kom meej cov xov haum ntawm threaded fasteners tom qab plating.

"Local thickness" nyob rau hauv tus qauv tiag tiag yog hais txog qhov tsawg kawg nkaus hauv zos thickness, uas piav txog qhov tsawg kawg nkaus tus nqi ntawm cov txheej thickness uas threaded fasteners yuav tsum tau ua tiav nyob rau hauv lub cheeb tsam xeem nto. Cov ntaub ntawv pov thawj kev sim qhia tau hais tias lub cheeb tsam txheej thickness ntsuas qhov ntsuas ntawm qhov ntsuas hauv cheeb tsam ntawm cov ntsia hlau, ntsia hlau taub hau, thiabntsia hlau, bolts, thiabtxiv ntseejyog ntau dua lawv cov batch nruab nrab thickness qhov tseem ceeb. Feem ntau, batch nruab nrab thickness tus nqi ua tau raws li qhov yuav tsum tau muaj, thiab qhov tsawg kawg nkaus hauv zos thickness kuj tuaj yeem ua tau raws li qhov yuav tsum tau ua. Cov txiaj ntsig kev xeem kuj tau lees paub tias qhov kev sib raug zoo ntawm tus lej ntawm "nominal txheej thickness", "batch nruab nrab thickness", thiab "loj thickness" yog qhov tseeb, uas yog lub hauv paus theoretical rau kev tshawb nrhiav thiab kev lees paub ntawm electroplating txheej thickness ntawm threaded fasteners.
