Hauv kev tsim tsheb, kev xaiv cov khoom siv blasting abrasives ua lub luag haujlwm tseem ceeb hauv kev txhim kho qhov zoo ntawm cov khoom siv tsheb. Cov khoom siv abrasives sib txawv muaj lawv tus kheej cov yam ntxwv tshwj xeeb thiab tsim nyog rau ntau theem ntawm kev tsim tsheb.
Rau kev kho ua ntej ua ntej siv cov primer rau lub cev tsheb, koj tuaj yeem xaiv cov khoom siv abrasives dawb corundum. Nrog rau qhov muaj zog, tiv taus kev hnav, thiab kev ruaj khov ntawm tshuaj lom neeg, lawv tuaj yeem tshem tawm cov txheej oxide, xeb, roj av, thiab cov txheej qub ntawm cov hlau sai sai. Lawv kuj tseem tuaj yeem tsim cov micro-roughness ntawm cov hlau, ua kom cov txheej nplaum zoo dua thiab ua kom muaj kev sib txuas ntawm cov txheej thiab cov hlau.
Yog tias tsim nyog yuav tsum tau txhuam thiab tshem cov khoom siv hauv tsheb kom raug, cov hlaws iav thiab xuab zeb garnet yog cov kev xaiv zoo. Lawv muaj qhov nyuaj nruab nrab thiab huv siab, uas tuaj yeem zam kev puas tsuaj rau lub substrate. Rau kev ntxuav tob thiab ua kom muaj zog ntawm cov khoom siv hauv tsheb, cov hlau txhaj tshuaj thiab cov hlau xuab zeb yog thawj qhov kev xaiv. Lawv muaj qhov nyuaj siab thiab muaj zog cuam tshuam, ua rau lawv tsim nyog rau kev tshem tawm cov xim tawv ncauj.
Yuav kom txhim kho qhov zoo ntawm kev kho qhov chaw, ntxiv rau kev xaiv cov khoom siv abrasive kom raug, cov txheej txheem kuj tseem yuav tsum tau ua kom zoo. Kho qhov siab ntawm kev tua kom raug kom ntseeg tau tias qhov ntxuav tau zoo yam tsis ua rau puas tsuaj rau qhov chaw ntawm cov khoom. Kho lub kaum sab xis ntawm lub nozzle rau 30 - 45 degrees kom ntseeg tau tias kev tua sib npaug. Teem lub sijhawm tua kom raug raws li qhov yuav tsum tau ua. Tsis tas li ntawd, cov khoom siv tsis siv neeg thiab semi-automatic tuaj yeem ua ke los txo cov kev ua yuam kev ntawm kev ua haujlwm tes thiab txhim kho kev ua haujlwm ntau lawm, yog li txhim kho qhov zoo ntawm kev tsim khoom tsheb.
