1. Plating thickness ntawm threaded fasteners
Txawm hais tias lub thoob plating lossis khib plating yog siv nyob rau hauv cov txheej txheem electroplating ntawm threaded fasteners, lub thickness ntawm txheej tau los ntawm txhua tus fastener nyob rau hauv ib pawg ntawm cov khoom yog txawv, thiab txheej txheej ntawm tib lub fastener kuj tsis sib xws. ntawm.
Piv txwv li, lub thickness ntawm cov txheej nyob rau sab saum toj ntawm cov xov yog thicker dua li ntawm nruab nrab txoj kab uas hla thiab hauv qab ntawm tus hniav, thiab lub thickness ntawm txheej ntawm ob kawg ntawm cov hniav.ntsia hlauthiab ntsia liaj qhov rooj yog tuab dua li qhov nruab nrab, thiab nws ua qhov tseem ceeb dua li qhov sib piv ntev-rau-inch nce. Tib yam muaj tseeb rau txiv ntseej. Vim cov nyhuv shielding thaum lub sij hawm txiv ntseej electroplating, lub thickness ntawm electroplating txheej ntawm cov xov sab hauv yog nyias nyias. Tsuas yog thawj tus khawm hniav ntawm ob qho kawg yog tuab dua li txheej hauv nruab nrab, uas yog sib npaug rau lub thickness ntawm hexagonal wrench nto. tuab.
2. Yuav ua li cas piav txog lub plating thickness ntawm ib batch ntawm threaded fasteners
Nyob rau hauv kev saib ntawm qhov tsis sib xws ntawm plating thickness ntawm threaded fasteners, plaub lub ntsiab lus ntawm plating thickness yog hais nyob rau hauv tus qauv, uas yog "nominal plating thickness", "batch nruab nrab thickness", "lub zos thickness" thiab "zoo plating thickness". "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 los ntawm "zoo txheej thickness". "Cov txheej txheem zoo" muaj ob yam: "batch nruab nrab thickness" thiab "lub zos thickness".
Lub plating thickness ntawm threaded fasteners tsis tuaj yeem sawv cev los ntawm plating thickness ntawm ib feem. Txawm hais tias cov threaded fasteners ua tiav los ntawm khib plating lossis chim plating, txhua qhov hauv tib pawg ntawm cov khoom tsis tuaj yeem ua tiav tib lub plating thickness, tab sis lub thickness ntawm cov kev hloov pauv yog ib txwm faib. Peb xav hais tias lub thickness ntawm txheej yog sib npaug zos rau saum npoo ntawm batch ntawm qhov chaw los xam qhov nruab nrab thickness ntawm txheej. Qhov no ua rau lub tswvyim ntawm "batch nruab nrab thickness", uas yuav siv tau los piav qhia tag nrho batch. Txheej thickness ntawm batch threaded fasteners.
Qhov "batch nruab nrab thickness" nyob rau hauv Standard Table 1 yog qhia raws li ib tug ntau yam. Qhov tsawg kawg nkaus batch nruab nrab thickness yog qhov yuav tsum tau los xyuas kom meej lub anti-corrosion ntawm threaded fasteners, thaum lub siab tshaj plaws batch nruab nrab thickness yog los xyuas kom meej lub threadability ntawm threaded fasteners tom qab plating.
"Local thickness" tiag tiag yog hais txog qhov tsawg kawg nkaus hauv zos thickness hauv tus qauv, thiab qhov tsawg kawg nkaus hauv zos thickness piav qhia txog qhov tsawg kawg nkaus tus nqi ntawm txheej txheej thickness uas cov threaded fastener yuav tsum ua tiav ntawm qhov chaw kuaj hauv zos. Cov ntaub ntawv pov thawj los ntawm qhov kev ntsuam xyuas qhia tau hais tias lub cheeb tsam txheej thickness ntsuas nyob rau hauv lub cheeb tsam xeem qhov chaw ntawm screws, ntsia liaj qhov rooj hau, thiab lub wrenching nto ntawm screws, bolts, thiab txiv ntseej yog tag nrho cov ntau dua lawv batch nruab nrab thickness qhov tseem ceeb, uas yog feem ntau. batch nruab nrab thickness qhov tseem ceeb. Tus nqi ua tau raws li qhov yuav tsum tau ua, thiab qhov tsawg kawg nkaus hauv zos thickness kuj ua tau raws li qhov yuav tsum tau ua. Cov txiaj ntsig kev xeem kuj tau lees paub tias cov lej sib raug zoo 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 plating thickness ntawm threaded fasteners.
