Qhov sib txawv ntawm txheej thickness gauge thiab non-destructive txheej thickness gauge
Qhov sib txawv ntawm cov txheej thickness gauge thiab cov non-destructive txheej thickness gauge yog raws li nram no. Txheej thickness gauges thiab non-destructive txheej thickness gauges yog ob qho tib si siv los ntsuas lub nominal thickness ntawm cov ntaub ntawv, tab sis muaj qee qhov sib txawv ntawm txheej thickness gauges thiab non-destructive txheej thickness gauges. Cia peb qhia qhov sib txawv ntawm cov txheej thickness gauge thiab cov uas tsis yog-destructive txheej thickness gauge nyob rau hauv kom meej.
Qhov txawv ntawm txheej thickness gauge thiab non-destructive txheej thickness gauge:
Txheej thickness gauge, feem ntau yog siv nyob rau hauv cov kev kho mob saum npoo kev lag luam, yog siv los ntsuas cov txheej thickness ntawm hlau los yog yas nto.
Tsis muaj kev puas tsuaj txheej thickness gauges muab faib ua ob hom: sib nqus thiab eddy tam sim no, thiab tseem muaj ob hom hom sib nqus eddy tam sim no. Nws yog feem ntau siv los ntsuas lub thickness ntawm nominal txheej uas lub substrate yog hlau, yog li nws kuj yog hu ua ib tug txheej thickness gauge.
Lub tshuab nqus hlau nplaum yog tsim los ntsuas lub thickness ntawm txheej nyob rau hauv cov hlau nplaum xws li hlau (tshwj tsis yog cov hlau nplaum xws li hlau thiab npib tsib xee), thiab cov txheej hauv qab cov hlau tsis sib nqus, txhuas, tin, thiab lwm yam tsis tuaj yeem ntsuas. Lub eddy tam sim no thickness gauge yog tsim los ntsuas lub thickness ntawm lub insulating txheej ntawm cov hlau tsis sib nqus, xws li tooj liab thiab txhuas (txheej txheej yuav tsum tsis yog-conductive).
