Tsis yog -Txoj kev kuaj kev puas tsuaj thiab cov ntsiab cai ntawm txheej txheej thickness ntsuas
Txoj kev ntsuas tsis yog -kev puas tsuaj thiab lub hauv paus ntsiab lus ntawm txheej txheej thickness gauge: Txheej thickness gauge yog ib tug cog lus qhuab qhia nrog muaj zog theoretical comprehensiveness thiab tseem ceeb heev rau cov tswv yim zoo nyob rau hauv lub tswv yim ntsuas. Nws suav nrog ntau yam xws li cov khoom siv lub cev ntawm cov khoom siv, cov khoom tsim, cov txheej txheem tsim khoom, kev sib tsoo tshuab, thiab kev suav cov ntsiab lus kawg.
Hauv kev lag luam xws li tshuaj lom neeg, hluav taws xob, hluav taws xob, thiab hlau, txhawm rau ua kom muaj kev tiv thaiv lossis kho kom zoo nkauj ntawm ntau yam ntaub ntawv, cov txheej txheem xws li tshuaj tsuag tsis yog -ferrous hlau coatings thiab phosphating, anodizing, thiab lwm yam. Qhov no tau ua rau muaj qhov tshwm sim ntawm cov ntsiab lus xws li txheej txheej, plating txheej, txheej txheej, cov ntawv nplaum, lossis cov yeeb yaj kiab tsim tawm, uas peb hu ua "coatings".
Kev ntsuas ntawm txheej thickness tau dhau los ua cov txheej txheem tseem ceeb rau kev soj ntsuam zoo ntawm cov khoom tiav hauv kev lag luam hlau. Nws yog ib qho tseem ceeb txhais tau tias rau cov khoom kom tau raws li * * qauv. Tam sim no, lub thickness ntawm txheej txheej yog feem ntau ntsuas raws li kev sib koom ua ke thoob ntiaj teb cov qauv hauv domestic thiab thoob ntiaj teb. Kev xaiv ntawm tsis yog -txoj kev kuaj kev puas tsuaj thiab cov cuab yeej rau txheej txheej tau dhau los ua qhov tseem ceeb ntxiv nrog rau kev nce qib ntawm kev tshawb fawb cov khoom ntawm lub cev.
Hais txog tsis yog -txoj kev kuaj kev puas tsuaj rau txheej txheej, feem ntau yog txoj kev txiav txiav, txoj kev txiav lub teeb, txoj kev electrolysis, thickness sib txawv ntsuas txoj kev, txoj kev hnyav, X- txoj kev fluorescence txoj kev, beta ray reflection method, capacitance method, magnetic measurement method, thiab eddy tam sim no ntsuas txoj kev. Tsuas yog tsib txoj kev dhau los, feem ntau ntawm cov txheej txheem no yuav tsum muaj kev puas tsuaj rau cov khoom lossis nws qhov chaw, uas yog ib daim ntawv ntawm kev puas tsuaj. Cov txheej txheem ntsuas yog cumbersome thiab qeeb, thiab feem ntau yog haum rau kev soj ntsuam kuaj.
X-ray thiab beta ray reflection txoj kev tuaj yeem siv rau kev tsis yog-kev sib cuag thiab tsis yog- ntsuas kev puas tsuaj, tab sis cov cuab yeej siv tau yooj yim thiab kim, thiab qhov ntsuas qhov ntsuas me me. Vim muaj cov khoom siv hluav taws xob, cov neeg siv yuav tsum ua raws li cov cai tiv thaiv hluav taws xob, uas feem ntau yog siv rau kev ntsuas thickness ntawm ntau yam hlau txheej.
