Sandblasting xeb tshem tawm yog ib txoj hauv kev siv cov cua compressed los tsav abrasive los ntawm kev kub ceev mus rau saum npoo ntawm lub workpiece, sai sai tshem tawm cov xeb txheej ntawm qhov chaw ntawm lub workpiece. Raws li txoj kev kho kom zoo thiab zoo ib puag ncig, sandblasting xeb tshem tawm tau siv dav hauv ntau qhov chaw.
Ua ntej, sandblasting tuaj yeem tshem tawm cov txheej txheej xeb, oxide nplai, roj stains thiab lwm yam khoom seem ntawm qhov chaw ua haujlwm. Cov residues no tsis tsuas yog cuam tshuam rau lub ntsej muag ntawm lub workpiece, tab sis kuj tseem tuaj yeem cuam tshuam rau nws txoj kev ua haujlwm thiab kev ua neej. Los ntawm sandblasting rau kev tshem tawm xeb, cov seem no tuaj yeem raug tshem tawm kom huv si hauv lub sijhawm luv luv, nthuav tawm cov xim zoo ib yam thiab zoo sib xws ntawm cov xim hlau ntawm qhov chaw ua haujlwm.
Thib ob, sandblasting tuaj yeem ua rau kom qhov roughness ntawm lub workpiece nto thiab txhim kho qhov zoo ntawm txheej. Los ntawm kev kho sandblasting, cov khoom sib xws thiab zoo concave thiab convex nto tuaj yeem tsim nyob rau ntawm qhov chaw ntawm lub workpiece, ua rau thaj chaw tshwj xeeb ntawm qhov chaw ua haujlwm, txhim kho qhov adhesion thiab txheej txheej zoo. Qhov no tuaj yeem txo tus nqi thiab zaus ntawm cov txheej txheem siv, thiab txo tus nqi ntawm txheej.
Tsis tas li ntawd, sandblasting xeb tshem tawm kuj tuaj yeem txhim kho cov khoom siv ntawm lub workpiece. Los ntawm kev kho sandblasting, compressive kev ntxhov siab tuaj yeem tsim tawm ntawm qhov chaw ua haujlwm, txhim kho nws lub zog qaug zog thiab corrosion kuj. Hom kev ntxhov siab no tuaj yeem txo qhov deformation thiab tawg ntawm lub workpiece thaum siv, thiab txuas ntxiv lub neej kev pab cuam ntawm workpiece.
Thaum kawg, sandblasting rau kev tshem tawm xeb yog ib qho kev tiv thaiv ib puag ncig. Piv nrog rau kev siv tshuab polishing thiab tshuaj ntxuav cov txheej txheem, sandblasting xeb tshem tawm tsis tsim cov plua plav thiab dej khib nyiab ntau, txo cov pa phem ib puag ncig. Nyob rau tib lub sijhawm, sandblasting kuj tseem tuaj yeem siv cov khoom seem tshem tawm, txo cov nqi pov tseg.
Hauv kev siv cov tswv yim, sandblasting xeb tshem tawm kuj muaj qhov zoo ntawm kev ua haujlwm yooj yim, ua haujlwm siab, thiab tus nqi qis. Piv nrog rau lwm txoj kev kho saum npoo, sandblasting xeb tshem tawm tuaj yeem xaiv qhov sib txawv roughness ntau ntau thiab muaj zog adaptability. Nyob rau tib lub sijhawm, sandblasting xeb tshem tawm kuj tuaj yeem ua tiav cov khoom siv hluav taws xob, txhim kho kev tsim khoom thiab zoo. Yog li ntawd, sandblasting xeb tshem tawm muaj dav daim ntawv thov kev cia siab nyob rau hauv ntau yam teb.
