Sandblasting yog txheej txheem ntawm kev ntxuav thiab roughening ntawm lub substrate los ntawm kev cuam tshuam ntawm cov xuab zeb ceev ceev. Cov cua compressed yog siv los ua lub zog los tsim lub dav hlau dav hlau ceev kom txau cov khoom siv blasting (garnet blasting abrasive, JadeBlast blasting abrasive, tooj liab ore xuab zeb, quartz xuab zeb, emery, hlau xuab zeb) rau saum npoo ntawm lub workpiece yuav tsum tau kho. ntawm kev kub ceev los ntxuav qhov chaw ntawm lub workpiece. Vim muaj kev cuam tshuam thiab txiav cov nyhuv ntawm cov abrasive ntawm qhov chaw ntawm lub workpiece, qhov saum npoo ntawm lub workpiece tuaj yeem tau txais qee qhov kev huv huv thiab qhov sib txawv ntawm qhov sib txawv, kom cov khoom siv ntawm lub workpiece nto zoo tuaj. , yog li txhim kho qhov qaug zog tsis kam ntawm cov khoom ua haujlwm, ua kom cov adhesion ntawm nws thiab txheej txheej, ua kom lub sijhawm ntev ntawm cov txheej txheej zaj duab xis, thiab tseem ua rau cov qib thiab kho kom zoo nkauj ntawm txheej.
Scope ntawm kev siv:
1. Txheej ntawm workpieces thiab sandblasting ua ntej workpiece bonding yuav tshem tawm tag nrho cov av xws li xeb thiab oxide daim tawv nqaij nyob rau saum npoo ntawm workpieces, thiab tsim ib tug tseem ceeb roughness nyob rau saum npoo ntawm workpieces (uas yog, lub thiaj li hu ua ntxhib nto), thiab tuaj yeem hloov tau los ntawm abrasives nrog ntau qhov sib txawv, xws li garnet 30/60 #, garnet 80 # lossis JadeBlast blasting abrasive 30/60 #, tuaj yeem ua tiav qib sib txawv ntawm roughness, uas zoo heev txhim kho lub zog sib txuas ntawm workpiece thiab xim thiab plating. . Los yog ua kom cov khoom sib txuas ruaj khov thiab zoo dua qub.
2. Qhov ntxhib nto ntawm castings thiab kev tu thiab polishing ntawm workpieces tom qab kev kho cua sov tuaj yeem ntxuav thiab xuab zeb blasted los ntxuav tag nrho cov av (xws li oxide nplai, roj thiab lwm yam seem) ntawm qhov chaw ntawm castings thiab forgings thiab workpieces tom qab kev kho cua sov. Lub workpiece nthuav tawm cov xim zoo ib yam thiab zoo ib yam hlau, uas ua rau cov duab ntawm lub workpiece zoo nkauj dua thiab zoo saib.
3. Lub burr tu thiab nto beautification xuab zeb blasting ntawm machined qhov chaw tuaj yeem ntxuav cov burrs me me rau ntawm qhov chaw ua haujlwm, ua kom lub ntsej muag ntawm lub workpiece smoother, tshem tawm cov kev puas tsuaj ntawm burrs, thiab txhim kho qib ntawm workpiece. Thiab sandblasting tuaj yeem ua rau cov fab me me ntawm qhov sib txuas ntawm qhov chaw ua haujlwm, ua rau cov khoom ua haujlwm zoo nkauj dua thiab meej dua.
4. Txhim kho cov khoom siv kho tshuab ntawm cov khoom. Tom qab sandblasting, cov khoom siv kho tshuab tuaj yeem tsim cov khoom sib xws thiab zoo concave thiab convex nto ntawm qhov chaw, yog li txhim kho cov txheej txheem lubrication, txo cov suab nrov thiab txhim kho kev pab cuam lub neej ntawm lub tshuab.
5. Rau qee lub hom phiaj tshwj xeeb workpieces, sandblasting tuaj yeem ua tiav qhov sib txawv los yog matt ntawm qhov xav tau. Xws li kev sib tsoo ntawm stainless hlau workpieces, txhuas qhov chaw, galvanized qhov chaw thiab cov yas, polishing ntawm jade khoom, mattization ntawm nto ntawm cov rooj tog ntoo, cov qauv qauv ntawm cov iav frosted, thiab texturing ntawm daim ntaub. .
Preprocessing theem:
Lub pretreatment theem ntawm cov txheej txheem sandblasting yog hais txog kev kho mob uas yuav tsum tau nqa tawm ntawm lub workpiece ua ntej lub workpiece yog sprayed thiab sprayed nrog ib tug tiv thaiv txheej.
Qhov zoo ntawm kev kho ua ntej ntawm cov txheej txheem sandblasting cuam tshuam rau adhesion, tsos, noo noo tsis kam thiab corrosion kuj ntawm txheej. Yog tias qhov kev ua haujlwm ua ntej tsis ua tiav zoo, cov xeb yuav txuas ntxiv mus rau hauv qab txheej, ua rau cov txheej txheem poob rau hauv daim. Qhov saum npoo uas tau ua tib zoo ntxuav thiab cov khoom ua haujlwm uas feem ntau ntxuav tau yooj yim tuaj yeem muab piv nrog cov txheej txheem los ntawm kev raug, thiab lub neej ntev yuav yog 4-5 zaus sib txawv. Muaj ntau txoj hauv kev ntawm kev ntxuav saum npoo, tab sis feem ntau lees txais txoj kev yog sandblasting.
Txheej txheem theem:
Cov txheej txheem sandblasting siv cov cua compressed raws li lub zog los tsim lub dav hlau dav hlau nrawm, thiab txau cov khoom siv thiab lwm cov dav hlau ceev ceev rau saum npoo ntawm lub workpiece yuav tsum tau kho, thiaj li hais tias cov tsos ntawm sab nrauv ntawm lub workpiece hloov. . Qee qhov kev huv huv thiab qhov sib txawv roughness txhim kho cov khoom siv ntawm lub workpiece nto.
