Dab tsi yog qhovkhoom pliguas ci ntsa iab thiab zoo li high-end?
Cov hlau yog nyob ze nrog huab cua txhua xyoo puag ncig, thiab cov txheej txheem feem ntau yog ntxiv rau saum npoo ntawm cov khoom plig, khoom plig, khoom plig nco txog, thiab lwm yam los muab qee yam kev tiv thaiv rau cov khoom siv hlau.
Cov hauv qab no yog 2022 Winter Olympics medals, uas tau sandblasted rau saum npoo. Niaj hnub no, cia peb qhia txog cov txheej txheem sandblasting.
Sandblasting yog txheej txheem ntawm kev kho deg rau workpieces. Siv cov cua compressed raws li lub zog, lub dav hlau ceev ceev yog tsim los rau cov khoom siv tshuaj tsuag (tooj liab ore, quartz xuab zeb, pob zeb diamond xuab zeb, hlau xuab zeb, dej hiav txwv xuab zeb) ntawm kev kub ceev mus rau saum npoo ntawm lub workpiece yuav tsum tau kho, ua rau muaj kev hloov hauv. qhov tsos lossis cov duab ntawm lub workpiece nto. Vim muaj kev cuam tshuam thiab txiav cov teebmeem ntawm abrasives rau ntawm qhov chaw ntawm lub workpiece, qhov saum npoo ntawm lub workpiece tau txais qee qhov kev huv huv thiab qhov sib txawv roughness, uas txhim kho cov khoom siv ntawm lub workpiece nto. Yog li ntawd, qhov qaug zog ua haujlwm ntawm lub workpiece yog txhim kho, adhesion ntawm nws thiab txheej yog nce, lub durability ntawm txheej yog ncua, thiab nws kuj yog conducive rau lub leveling thiab kho kom zoo nkauj ntawm txheej.
Cov khoom siv raw rau kev kho sandblasting
Sandblasting: Ib lo lus kev siv hauv kev nrum kub thiab nyiaj npib. Ntawm cov pwm tsim ntawm kub thiab nyiaj npib, ntau qhov ntau thiab tsawg thiab cov qauv ntawm cov xuab zeb hlau yog siv los txau cov qauv rau hauv ib qho chaw zoo nkauj heev. Thaum tsim cov kub thiab nyiaj npib, ib qho kev ntxhib los mos zoo nkauj tshwm rau ntawm tus qauv, ua rau kev nkag siab ntawm qhov ntev thiab txheej txheej. Sandblasting: (hais txog kev tshem tawm cov xeb ntawm cov hlau los yog plating ntawm cov hlau) yog muab faib ua cov xuab zeb zoo tib yam quartz thiab cov xuab zeb ua kom zoo quartz: nrog cov hardness siab thiab zoo xeb tshem tawm cov nyhuv.
Sandblasting txheej txheem
Ua ntej txheej txheem
Cov theem ua ntej kev kho mob ntawm cov txheej txheem yog hais txog kev kho mob uas yuav tsum tau nqa tawm ntawm qhov chaw ntawm lub workpiece ua ntej yuav tsum tau txau los yog coated nrog ib tug tiv thaiv txheej. Qhov zoo ntawm kev kho mob ua ntej hauv kev siv tshuab sandblasting cuam tshuam rau adhesion, tsos, noo noo tsis kam, thiab corrosion kuj ntawm coatings. Yog tias qhov kev kho mob ua ntej tsis ua tiav zoo, xeb yuav txuas ntxiv mus rau hauv qab txheej, ua rau cov txheej txheem tev tawm hauv daim. Tom qab ua tib zoo ntxuav ntawm qhov chaw thiab kev tu yooj yim ntawm lub workpiece, lub neej txheej yuav raug muab piv los ntawm 4-5 zaug siv txoj kev raug tshav ntuj. Muaj ntau txoj hauv kev rau kev ntxuav saum npoo, tab sis feem ntau lees txais yog kev ntxuav cov kua qaub, ntxuav cov cuab yeej, thiab cov cuab yeej siv phau ntawv.
Txheej txheem theem
Cov txheej txheem sandblasting siv cov cua compressed raws li lub zog los tsim lub dav hlau dav hlau ceev, uas txau cov ntaub ntawv thiab lwm yam ntaub ntawv mus rau saum npoo ntawm lub workpiece yuav tsum tau kho ntawm kev kub ceev, ua rau muaj kev hloov ntawm qhov chaw ntawm lub workpiece. Vim muaj kev cuam tshuam thiab txiav cov teebmeem ntawm abrasives ntawm qhov chaw ua haujlwm, qhov chaw ua haujlwm tau txais qee qhov kev huv huv thiab sib txawv roughness, txhim kho cov khoom siv ntawm lub workpiece nto.
Cov txiaj ntsig ntawm kev siv tshuab sandblasting
(1) Txheej thiab kev sib txuas ua ntej kev kho sandblasting tuaj yeem tshem tawm tag nrho cov av xws li xeb ntawm qhov chaw ua haujlwm, thiab tsim cov qauv tseem ceeb heev (feem ntau hu ua ntxhib nto) ntawm qhov chaw. Nws tseem tuaj yeem ua tiav qhov sib txawv ntawm qhov ntxhib los ntawm kev sib hloov cov khoom sib txawv ntawm qhov sib txawv ntawm qhov sib txawv, xws li ya cov cuab yeej abrasive, zoo heev txhim kho lub zog sib txuas ntawm cov coatings thiab coatings. Los yog ua rau kev sib txuas ntawm cov nplaum qhov chaw ruaj khov thiab zoo dua.
(2) Qhov ntxhib ntawm cov castings thiab kev tu thiab polishing tom qab kev kho cua sov tuaj yeem raug ntxuav los ntawm cov xuab zeb blasting, uas tuaj yeem tshem tawm tag nrho cov av (xws li oxide daim tawv nqaij, roj stains, thiab lwm yam) ntawm qhov chaw ntawm forged thiab kub-kho workpieces. Cov polishing nto tuaj yeem txhim kho qhov smoothness ntawm lub workpiece, nthuav tawm cov xim zoo ib yam thiab zoo ib yam xim hlau, ua rau cov tsos zoo nkauj dua thiab ntxim nyiam.
(3) Burr tu thiab deg beautification sandblasting tuaj yeem ntxuav cov burrs me me rau ntawm qhov chaw ua haujlwm, ua kom lub ntsej muag ntawm cov workpieces smoother, tshem tawm cov teeb meem ntawm burrs, thiab txhim kho qib. Thiab sandblasting tuaj yeem tsim cov kab me me me me ntawm qhov sib cuam tshuam ntawm qhov chaw ua haujlwm, ua rau nws zoo nkauj dua thiab meej.
(4) Tom qab sandblasting, zoo ib yam thiab zoo concave convex nto tuaj yeem tsim rau ntawm qhov chaw, cia cov roj lubricating khaws cia, yog li txhim kho cov txheej txheem lubrication thiab txo cov suab nrov kom muaj kev pab cuam lub neej.
(5) Rau qee lub hom phiaj tshwj xeeb workpieces, sandblasting tuaj yeem ua tiav cov kev xav sib txawv lossis cov teebmeem matte ntawm qhov xav tau. Xws li polishing stainless hlau workpieces thiab yas, polishing jade khoom, matte nto kho cov rooj tog ntoo, qauv qauv ntawm frosted iav nto, thiab roughening ntawm ntaub nto.
Zuag qhia tag nrho, nws ua rau cov khoom plig kub tshwm sim ntau dua, ruaj khov thiab ruaj khov
