1.Thaum xuab zeb blasting los yog phau ntawv siv tshuab derusting yog siv, cov hlau nplai ntawm qhov chawloj-inch steel yeeb nkab yog ncaj qha mus rau huab cua vim yog tev ntawm oxide nplai los ntawm cov yeeb nkab loj-inch.Yog tias cov primer tsis pleev xim rau lub sijhawm, qhov saum npoo ntawm cov yeeb nkab loj-inch steel yuav zoo li xeb dua, uas cuam tshuam rau qhov adhesion ntawm cov xim pleev xim.Txij li cov xim yog cov khoom siv sij hawm-sensitive, cov khoom lag luam rov qab yog feem ntau yuav tas sij hawm thiab ua tsis raug.Yog li ntawd, cov cim tseem ceeb ntawm cov xim yog rov kuaj dua ua ntej siv, thiab cov txiaj ntsig tau raws li tus qauv.

2.Derusting: Qhov no yog txheej txheem tseem ceeb ua ntej txheej ntawm cov kav hlau loj thiab cov khoom, thiab yog tus yuam sij rau cov kav hlau loj.Kev tshem tawm xeb tuaj yeem txhim kho qhov adhesion ntawm cov xim xeb, yog li txuas ntxiv kev pabcuam lub neej ntawm cov kav hlau loj.

3.Qhov saum npoo ntawm qhov loj-inch steel yeeb nkab ua tiav los ntawm sandblasting, tua blasting lossis pickling txheej txheem yog huv si, thiab oxide nplai thiab xeb kuj huv si, uas txhim kho cov txheej txheej adhesion.Thaum lub chaw teeb tsa tsis muaj kev kho mob los ntawm sandblasting thiab txhaj tshuaj blasting, phau ntawv tshuab tuaj yeem siv rau kev tshem tawm xeb, tab sis qib kev tshem tawm xeb tau mus txog.
