Yuav siv cov txheej thickness ntsuas li cas kom tsis txhob txo qhov yuam kev
Thaum siv cov txheej thickness gauge los ntsuas, sim siv cov khoom ntsuas raws li xoom-hloov substrate kom tsis txhob ntsuas qhov yuam kev los ntawm cov khoom sib txawv nrog cov sib nqus permeability. Tos kom txog thaum tib qhov ntawm cov khoom yuav tsum tau kuaj yog xoom, thiab tom qab ntawd ntsuas qhov qub, xws li ntug thiab nruab nrab ntawm cov khoom ua haujlwm ntawm lub ntsej muag sab, uas yuav tsum tau xoom cais.
Thaum ntsuas nrog cov txheej thickness gauge, nws yuav tsum tau muab sau tseg tias cov sojntsuam thiab cov nto ntawm cov khoom yuav tsum tau ntsuas yog khaws cia ntsug kom tsis txhob loj yuam kev. Yog hais tias qhov ntsuas yog nyob rau tib lub ntsiab lus, qhov kev sojntsuam tuaj yeem sib cais los ntawm ntau tshaj 10 cm txhua lub sijhawm, thiab kev ntsuas yuav tsum tau ua tom qab ob peb feeb, kom tsis txhob ntsuas qhov tshwm sim cuam tshuam los ntawm kev sib nqus ntawm kev sojntsuam. ntsuas cov khoom.
Qhov saum npoo ntawm txheej thickness gauge siv rau xoom hloov yuav tsum tau khaws cia kom du li sai tau. Yog tias qhov saum npoo tsis du, qhov nruab nrab tus nqi yuav tsum tau ua raws li qhov xwm txheej, vim tias qhov roughness ntawm qhov chaw muaj qhov cuam tshuam zoo rau qhov ntsuas tus nqi. Cov qauv sib txawv yuav tsum tau ntsuas cais nrog xoom hloov kho, lub dav hlau yog xoom thiab lub ntsej muag lub ntsej muag yog ntsuas, lub ntsej muag concave yog ntsuas tom qab zeroing, thiab lub ntsej muag convex yog ntsuas tom qab zeroing, kom tsis txhob muaj qhov yuam kev hauv kev ntsuas vim txawv cov qauv.
