Yog tias siv lub tshuab ua teb los so, cov paj rwb yuav tsum txav mus rau hauv txoj kab ncaj nraim los ntawm qhov chaw mus rau ntawm ntug, thiab cov paj rwb nws tus kheej yuav tsum tig ib txhij (kev sib hloov ntawm cov paj rwb yuav tsum me ntsis tsawg dua ib lub voj voog).
4. Thaum so lub prism, ib lub paj rwb tuaj yeem muab tso rau hauv kab rov tav ntawm qhov chaw kom so thiab so hauv txoj kab ncaj nraim.
5. Nws yuav tsum tau muab so rau hauv ib chav huv si thiab so nrog degreased ntev staple paj rwb. Cov tshuaj ntxuav ntawm cov paj rwb yuav tsum tsis txhob ntau dhau. Thaum so, nws yuav tsum tau txav mus thiab so hauv qhov kev taw qhia hla ntawm lub reticle kom tsis txhob so tawm cov txheej ntim hauv lub reticle.
6. Thaum so cov khoom siv kho qhov muag, cov paj rwb yuav tsum tsis txhob dipped nyob rau hauv ntau sib tov los tiv thaiv hnyav los ntawm invading txheej glued thiab ua rau delamination.
7. Reflective qhov chaw coated nrog txhuas thiab cov yeeb yaj kiab tiv thaiv tuaj yeem so nrog paj rwb pob dipped nyob rau hauv ib qho me me ntawm cov kua sib xyaw los yog ua tib zoo degreased sandcloth yog tias cov yeeb yaj kiab tiv thaiv yog qhov ruaj khov.
8. Cov paj rwb yuav tsum tau dov zoo, thiab lub taub hau ntawm cov xyoob ntoo siv los yob cov paj rwb yuav tsum tsis txhob raug kom tsis txhob khawb qhov chaw. Qhov loj thiab cov duab ntawm cov paj rwb yuav tsum sib txawv nyob ntawm qhov loj thiab hom ntawm qhov chaw. Feem ntau, cov paj rwb cylindrical yog siv rau qhov chaw ncig, cov paj rwb tiaj tus yog siv rau qhov chaw tiaj tus, thiab cov paj rwb mos yog siv rau txheej txheej (tshwj xeeb tshaj yog muaj kev cuam tshuam magnesium). Hauv lwm qhov xwm txheej, cov paj rwb yuav tsum tau nruj nreem dov.
9. Thaum cov paj rwb dipped hauv qhov sib tov nkag mus rau hauv cov kuab tshuaj, thov tsis txhob tshaj ib feem peb ntawm qhov ntev ntawm cov paj rwb.
