Ib qho infrared scan ntawm lub xovxwm platen tuaj yeem nthuav tawm ib qho, kub siab pixels - lub teeb ci ntsa iab, lub teeb pom kev zoo hauv cheeb tsam -tsis tau txhua qhov kev ntsuas hluav taws xob ntawm lub tshuab hluav taws xob sab hauv thiab cov thermocouples tuaj yeem rov qab nyeem ib txwm. Cov cua sov ua haujlwm kom raug, thiab cov sensors qhia meej meej, tab sis qhov saum npoo tseem pom qhov chaw ci ntsa iab. Qhov tshwm sim no tsis yog kev txhaum sab hauv; nws yog ib qho khoom siv thermal uas tshwm sim los ntawm ib qho me me, feem ntau pom tsis tau, cov khoom txawv teb chaws zaum ncaj qha rau ntawm qhov chaw platen.

Feem ntau ua rau cov chaw kub kub

Ob qhov xwm txheej tseem ceeb piav qhia qhov kev xav tsis meej ntawm qhov chaw no:

1. Reflective lossis Emissive Contaminants

Ib qho me me ntawm cov hlau uas muaj qhov cuam tshuam zoo heev, xws li cov hlau tsis muaj hlau tsis zoo, tuaj yeem hloov kho cov duab thermal. Cov kab mob no muaj kev cuam tshuam cov cua sov los ntawm ib puag ncig kub platen, tsom rau hauv ib qho chaw me me thiab tshwm sim raws li qhov chaw kub kub rau lub koob yees duab infrared. Qhov tseeb qhov kub ntawm cov hlau yuav zoo ib yam nrog cov platen, tab sis nws qhov muag kos npe yog exaggerated.

2. Reactive Polymer residues

Ib qho kev txhawj xeeb ntxiv yog qhov kho qhov poob ntawm cov khoom siv polymer, xws li exothermic epoxy lossis cyanate ester resin. Cov speck me me no tuaj yeem nqus cov cua sov ntxiv vim nws qhov sib txawv emissivity, lossis nws tuaj yeem tsim cov tshuaj tiv thaiv me me ntawm nws tus kheej. Cov khoom zoo li no ua rau saum npoo - qhov chaw kub qhov chaw tsis qhia tias muaj hluav taws xob lossis kev ua haujlwm tsis zoo hauv lub platen.

Ib qho me me me me ntawm cov av ntawm qhov chaw tuaj yeem qw nrov rau lub koob yees duab infrared dua li tag nrho cov platen noj qab haus huv.

Diagnostic txheej txheem

Ua tib zoo tshuaj xyuas infrared kom paub meej tias muaj qhov kub ntawm qhov chaw.

Lub cev ntxuav qhov chaw cuam tshuam nrog cov ntaub mos mos thiab cov kuab tshuaj uas tsim nyog. Tsis txhob siv cov khoom siv abrasive uas tuaj yeem ua kom puas lub platen nto.

Re-scan lub platen nrog lub koob yees duab infrared kom paub tseeb tias qhov chaw kub tau ploj mus.

Cov kauj ruam tu no yog qhov tseeb kuaj xyuas kom paub meej tias qhov tsis xws luag yog nto- cuam tshuam es tsis yog qhov ua txhaum ntawm lub tshuab cua sov sab hauv.

Kev txiav txim siab

Emissivity sib txawv yog ib txwm ua rau pom tseeb thermal artifacts.

Cov me me, muaj qhov cuam tshuam zoo heev ntawm cov hlau tawg lossis cov khoom siv polymer uas kho tau tuaj yeem tsim cov cim kos npe tsis raug.

Lub cev so ntawm platen nto yog txoj kev txhim khu kev qha tshaj plaws los daws qhov phantom kub qhov chaw.

Xaus

Ib qho phantom, qhov chaw kub hauv cheeb tsam uas tsis muaj qhov tsis txaus ntseeg sab hauv yog yuav luag txhua qhov tshwm sim ntawm qhov chaw - theem kab mob. Ua tib zoo tu ntawm platen nto tshem tawm cov khoom cuav thiab rov ua kom zoo ib yam thermal profile. Lub koob yees duab infrared rhiab tshaj plaws tuaj yeem dag los ntawm cov plua plav microscopic, hais txog tias tsis yog txhua qhov chaw ci ntsa iab qhia qhov tsis ua haujlwm sab hauv.
