Qhov sib txawv ntawm txheej txheej thickness gauge thiab ib tug tsis-destructive txheej thickness gauge
Lub ntsiab sib txawv ntawm txheej thickness gauges thiab non-destructive txheej thickness gauges yog raws li nram no. Txheej thickness gauges thiab non-destructive txheej thickness gauges yog ob leeg siv los ntsuas lub nominal thickness ntawm cov ntaub ntawv. Txawm li cas los xij, muaj qee qhov sib txawv ntawm txheej thickness gauges thiab non-destructive coating thickness gauges. Hauv qab no peb yuav ua kom paub meej qhov sib txawv ntawm txheej thickness gauges thiab non-destructive txheej thickness gauges.
Qhov txawv ntawm txheej thickness gauge thiab non-destructive txheej thickness gauge:
Txheej thickness gauge yog tsuas yog siv nyob rau hauv kev kho mob saum npoo kev lag luam los ntsuas cov txheej thickness ntawm hlau los yog yas nto.
Tsis yog-kev puas tsuaj txheej thickness gauges muab faib ua ob hom: magnetic thiab eddy tam sim no. Kuj tseem muaj cov hlau nplaum thiab eddy tam sim no ob-hauv-ib hom kev siv dual. Nws yog feem ntau siv los ntsuas lub thickness ntawm txheej txheej uas lub substrate yog hlau, yog li nws tseem hu ua txheej thickness gauge.
Lub tshuab magnetic thickness gauge yog tsim los ntsuas lub thickness ntawm coatings ntawm cov hlau nplaum xws li hlau (txuas tsis yog hlau nplaum, xws li hlau thiab npib tsib xee), tab sis tsis tuaj yeem ntsuas cov coatings ntawm cov hlau tsis sib nqus, txhuas, tin, thiab lwm yam. thickness gauge yog tsim los ntsuas lub thickness ntawm cov rwb thaiv tsev txheej ntawm cov hlau uas tsis yog hlau nplaum, xws li tooj liab thiab txhuas (cov txheej yuav tsum yog cov khoom uas tsis yog-conductive).
Qhov sib txawv ntawm cov hlau nplaum (hlau-raws li) thiab eddy tam sim no (tsis yog hlau-raws li) txheej thickness gauges
Txheej thickness gauge magnetic (hlau-raws li) ntsuas lub thickness ntawm non-magnetic coatings (xws li txhuas, chromium, tooj liab, enamel, roj hmab, xim, thiab lwm yam) ntawm cov hlau nplaum hlau substrates (xws li hlau, hlau, alloys thiab nyuaj magnetic. steel, thiab lwm yam)
Txheej thickness gauge eddy tam sim no (tsis yog-ferrous raws li) ntsuas lub thickness ntawm non-conductive coatings (xws li enamel, roj hmab, xim, yas, thiab lwm yam) ntawm cov hlau tsis sib nqus hlau substrates (xws li tooj liab, txhuas, zinc, tin, lwm yam).
Sib nqus (Iron-based) Hom F:
Ntsuas cov tuab ntawm cov hlau tsis sib nqus ntawm cov hlau, hlau thiab lwm yam ferromagnetic hlau substrates, xws li: xim, hmoov, ntau yam tshuaj tiv thaiv corrosion, plastics, roj hmab, cov khoom siv hluavtaws, phosphate txheej, chromium, zinc, lead, tin, cadmium. tos;
Eddy tam sim no (non-ferrous raws li) N hom:
Ntsuas lub thickness ntawm tag nrho cov uas tsis yog-conductive txheej ntawm non-ferromagnetic substrates xws li tooj liab, txhuas, stainless hlau, xws li: xim, hmoov, ntau yam anti-corrosion txheej, yas, roj hmab, khoom hluavtaws, phosphate txheej, oxide txheej, thiab lwm yam. .;
