Sandblasting rau kev tshem tawm xeb yog ib qho ntawm cov txheej txheem zoo ua ntej kev kho mob. Nws tsis tsuas yog tuaj yeem tshem tawm cov nplais oxide, xeb, cov xim pleev xim qub, cov roj stains thiab lwm yam impurities los ntawm cov hlau nto, ua rau cov hlau saum npoo pom cov xim hlau tsis sib xws, tab sis kuj tuaj yeem muab cov hlau nto ib yam roughness kom tau ib tug uniformly ntxhib nto. Nws tseem tuaj yeem hloov kho cov txheej txheem kev ntxhov siab rau hauv compressive kev nyuaj siab, txhim kho cov adhesion ntawm cov txheej txheem tiv thaiv corrosion thiab lub hauv paus hlau nrog rau kev tiv thaiv corrosion ntawm hlau nws tus kheej.
Muaj peb hom sandblasting: qhuavxuab zebtawg, ntubxuab zebblasting thiab nqus tsev vacuumxuab zebtawg. Koj puas paub lawv qhov zoo thiab qhov tsis zoo?
I.Dry sandblasting:
Qhov zoo:
Kev kub ceev thiab kev ua haujlwm zoo, haum rau cov workpieces loj thiab daim ntawv thov uas yuav tsum tau tshem tawm cov av hnyav.
Qhov tsis zoo:
Ua kom muaj plua plav thiab abrasive residue ntau, uas tuaj yeem ua rau ib puag ncig muaj kuab lom thiab abrasive tuav. Static adsorption ntawm abrasives yog ib qho teeb meem tshwm sim.Surface reinforcing:
Txhaj tshuaj tua blasting cov ntaub ntawv residual compressive kev nyuaj siab ntawm qhov chaw los ntawm kev kub ceev txhaj tshuaj blasting, yog li txhim kho lub zog qaug zog thiab hnav tsis kam ntawm cov ntaub ntawv.
II.ntubxuab zebtawg
Qhov zoo:
Dej tuaj yeem ntxuav cov khoom siv abrasive, txo cov plua plav, tawm tsawg dua qhov seem ntawm qhov chaw, thiab tiv thaiv hluav taws xob zoo li qub adsorption. Nws yog tsim rau decontamination thiab deg kev kho mob ntawm precision qhov chaw, tsis txhob ntxiv kev puas tsuaj rau lub workpiece nto.
Qhov tsis zoo:
Qhov ceev yog qeeb dua qhov qhuavsandblasting. Cov dej nruab nrab yuav ua rau corrosion rau lub workpiece, thiab qhov teeb meem ntawm kev kho dej yuav tsum tau xav txog.
III. Vacuuum sandblasting
Nqus sandblasting yog hom qhuav sandblasting. Nws yog ib txoj hauv kev tshwj xeeb hauv cov tshuab sandblasting qhuav uas siv lub tshuab nqus tsev vacuum siv los ntawm cov cua compressed kom ceev cov tshuaj tsuag ntawm cov ntaub ntawv abrasive. Qhuav sandblasting tau muab faib ua cua dav hlau hom thiab hom centrifugal. Lub tshuab nqus tsev sandblasting belongs rau huab cua dav hlau hom thiab siv cua ntws los txau cov ntaub ntawv abrasive ntawm kev kub ceev mus rau saum npoo ntawm cov khoom ua haujlwm. Nws yog tshwj xeeb tshaj yog haum rau workpieces uas tsis haum rau kev kho dej los yog kua.
Qhov zoo:
Lub workpiece thiab abrasive raug kaw tag nrho hauv lub thawv, tiv thaiv kom tsis txhob muaj plua plav tawm. Qhov chaw ua haujlwm yog huv si thiab yuav tsis muaj cov khoom abrasive ya ncig hauv huab cua. Qhov no yog qhov tsim nyog rau kev ua cov khoom precision nrog cov kev xav tau siab heev rau ib puag ncig thiab qhov tseeb ntawm qhov chaw ua haujlwm.
Qhov tsis zoo:
Kev khiav hauj lwm ceev yog qeeb. Nws tsis tsim nyog rau kev ua cov khoom loj loj thiab cov khoom siv yog tus nqi siab.
