Tej yam cuam tshuam rau kev ntsuas qhov tseem ceeb thiab cov kev daws teeb meem sib xws
1. Ciam teb sib nrug
Yog hais tias qhov kev ncua deb ntawm qhov kev sojntsuam thiab tus ciam teb, qhov, kab noj hniav, lossis lwm yam ntoo khaub lig- ntu kev hloov pauv ntawm cov khoom ntsuas tsawg dua li qhov kev ncua deb ntawm ciam teb, ntsuas qhov yuam kev yuav tshwm sim vim tsis txaus hla - ntu ntawm cov hlau nplaum flux lossis eddy cov cab kuj tam sim no. Yog hais tias nws yog tsim nyog los ntsuas lub thickness ntawm lub txheej ntawm lub point no, nws tsuas yog yuav tsum tau ntsuas los ntawm pre calibrating rau ib tug uncoated nto nyob rau hauv tib yam mob. (Ceeb Toom: Cov khoom tshiab muaj qhov tshwj xeeb ntawm kev ua tiav qhov tseeb ntawm 3-10% los ntawm txheej txheej calibration.)
2. Nto curvature ntawm substrate
Calibrate tus nqi pib ntawm tus qauv sib piv tiaj tus, thiab tom qab ntawd rho tawm tus nqi pib tom qab ntsuas cov txheej tuab. Lossis xa mus rau cov lus hauv qab no.
3. Nto roughness thiab deg huv si
Txhawm rau kom tau txais tus sawv cev ntsuas qhov nruab nrab ntawm qhov chaw ntxhib, ntau qhov ntsuas yuav tsum tau ua. Nws yog pom tseeb tias qhov rougher lub substrate los yog txheej, qhov tsawg txhim khu kev qha tus nqi ntsuas. Yuav kom tau txais cov ntaub ntawv txhim khu kev qha, qhov nruab nrab roughness Ra ntawm lub substrate yuav tsum tsawg dua 5% ntawm cov txheej thickness. Rau deg impurities, lawv yuav tsum tau muab tshem tawm. Qee cov cuab yeej muaj qhov txwv sab sauv thiab qis kom tshem tawm cov 'cov ntsiab lus ya'.
4. Kev quab yuam tawm ntawm lub rooj ntsuas kev sojntsuam
Lub zog siv thaum ntsuas ntsuas yuav tsum tsis tu ncua. Thiab nws yuav tsum tsawg li tsawg tau. Txhawm rau tiv thaiv deformation ntawm cov txheej mos thiab txo qhov ntsuas qhov ntsuas. Yog tias muaj kev hloov pauv loj hauv kev ua haujlwm, ib qho nyuaj, tsis yog - conductive, thiab tuab zaj duab xis tuaj yeem muab tso rau ntawm ob yog tias tsim nyog. Los ntawm rho tawm cov thickness ntawm zaj duab xis, residual magnetism tuaj yeem tsim nyog tau.
5. Sab nraud tas li magnetic teb, electromagnetic teb, thiab residual magnetism ntawm lub substrate
Kev ntsuas yuav tsum tsis txhob nyob ze rau sab nraud magnetic teb uas yuav ua rau muaj kev cuam tshuam. Qhov seem hlau nplaum yuav ua rau kev ntsuas tsis raug rau qhov sib txawv nyob ntawm qhov kev ua haujlwm ntawm lub tshuab ntes, tab sis cov xwm txheej zoo li no feem ntau tsis tshwm sim hauv cov qauv hlau, sib sib zog nqus kos cov hlau phaj, thiab lwm yam.
6. Ferromagnetic thiab conductive Cheebtsam nyob rau hauv cov ntaub ntawv txheej
Thaum qee yam ferromagnetic Cheebtsam, xws li qee cov pigments, muaj nyob rau hauv txheej, lawv tuaj yeem cuam tshuam rau qhov ntsuas. Nyob rau hauv cov ntaub ntawv no, txheej ntawm cov qauv siv rau calibration yuav tsum muaj tib yam electromagnetic yam ntxwv raws li cov txheej ntawm cov khoom kuaj thiab yuav tsum tau siv tom qab calibration. Cov txheej txheem siv tuaj yeem siv tib txheej txheej rau cov qauv txhuas lossis tooj liab phaj, thiab tau txais cov qauv piv txwv tom qab kuaj nrog eddy tam sim no txoj kev. Nws kuj tseem tuaj yeem yuav los ntawm cov tuam tsev ntsuas ntsuas thiab ntsuas ntsuas
