Cov xuab zeb blasting txheej txheem ntawm titanium thiab titanium alloy cov ntaub ntawv yog ib qho tseem ceeb ntawm cov txheej txheem kho deg, lub hom phiaj yog tshem tawm cov oxide txheej thiab cov pa phem rau ntawm qhov chaw, los txhim kho qhov roughness ntawm lub substrate, txhim khu lub adhesion ntawm txheej, los yog muab qhov tshwj xeeb physicochemical thaj chaw, los txhim kho cov khoom siv kho tshuab ntawm cov khoom thiab lwm yam.
Sandblasting yog siv cov huab cua compressed los yog dej ntws yuav ua rau abrasive high-speed tsuag rau saum npoo ntawm titanium alloy, thiaj li yuav tshem tawm cov oxide txheej, av thiab impurities, thiaj li yuav txhim kho qhov roughness thiab adhesion. Txoj kev no feem ntau yog siv rau hauv kev kho deg ntawm titanium castings thiab forgings kom ntseeg tau tias cov nyhuv adhesion ntawm kev ua tom ntej lossis txheej.
Blasting tsis yog tsuas yog siv los ntxuav thiab roughen saum npoo, tab sis kuj los txhim kho microstructure ntawm cov khoom los ntawm kev kho qhov tsis. Piv txwv li, cov nplej loj ntawm titanium alloys tuaj yeem raug txo kom txog li 44 nanometers los ntawm kev tawg nrog ib txoj kab uas hla ntawm 0.5 mus rau 2 millimeters, uas ua rau lawv qaug zog siab ntev thiab tiv thaiv kev ntxhov siab tawg. Tsis tas li ntawd, ntub blasting tshuab ua ke nrog ultrasonic kev co tuaj yeem txuas lub neej txhaj tshuaj thiab ua kom lub zog muaj zog hauv zos thaum txo qhov roughness.
Kev txhaj tshuaj peening muaj ntau yam kev siv hauv kev kho mob cog, aerospace thiab lwm qhov chaw. Piv txwv li, sandblasting ntawm qhov chaw cog qoob loo tuaj yeem ua rau thaj chaw ntog, txhawb nqa cell adhesion thiab proliferation, thiab txhim kho osseointegration. Nyob rau hauv kev sib xyaw molding ntawm composites thiab titanium alloys, sandblasting tuaj yeem txhim kho lub zog shear, uas yog qhov zoo rau kev sib txuas ntawm cov khoom sib xyaw thiab titanium alloys.
Sandblasting txheej txheem
1. Dry sandblasting txheej txheem: - Qhuav sandblasting yog cov txheej txheem sandblasting ntau tshaj plaws, uas siv cov cua compressed los ua lub zog rau blasting abrasive cov ntaub ntawv (xws li quartz xuab zeb, pob zeb diamond xuab zeb, hlau xuab zeb, thiab lwm yam) mus rau saum npoo ntawm lub workpiece kom tiav. lub hom phiaj ntawm kev ntxuav, deburring, nce nto roughness, thiab lwm yam raws li qhov sib txawv, cov grits sib txawv raug xaiv kom tau raws li qhov sib txawv ntawm cov khoom siv. - Raws li qhov sib txawv, xaiv qhov sib txawv particle loj abrasives thiab compressed cua siab. Piv txwv li, cov hlau loj dua li 3 hli tuab tuaj yeem siv 2.5-.5 hli quartz xuab zeb thiab 0.3 ~ 0.5MPa compressed cua siab.
2. Cov txheej txheem ntub dej blasting: - ntub blasting zoo ib yam li qhuav blasting, tab sis dej ntxiv rau cov abrasive los ua cov slurry uas txo cov plua plav paug thiab txo qhov kub ntawm qhov chaw ua haujlwm. ntub xuab zeb blasting feem ntau yog siv nyob rau hauv lub sij hawm uas yuav tsum tau ib tug siab ntawm ib puag ncig huv huv.
3. Shot Peening: - Kev txhaj tshuaj zoo ib yam li sandblasting, tab sis siv cov abrasive kheej kheej (xws li steel lossis iav txhaj tshuaj) es tsis txhob siv cov xuab zeb abrasive. Kev txhaj tshuaj blasting tuaj yeem tsim kev ntxhov siab, txhim kho qhov qaug zog ntawm qhov chaw thiab tiv thaiv kev ntxhov siab corrosion, feem ntau siv rau hauv kev kho deg ntawm precision qhov chaw.
4. Siphon blasting: - Siphon blasting siv lub raj siphon los kos cov abrasive rau hauv cov kwj deg thiab yog siv rau kev npaj nto ntawm me me, complex zoo li qhov chaw.
5. Kev kub siab blasting: - Kev kub siab blasting siv lub thawv uas muaj zog los thawb tawm cov khoom abrasive ntawm kev kub ceev thiab tsim nyog rau kev kho deg ntawm cov cheeb tsam loj, nrog kev ua haujlwm siab, tab sis kuj muaj cov khoom siv ntau dua.
6. Kev blasting ntub dej: - ntub blasting sib xyaw ua ke dej nrog cov khoom siv abrasive kom txo cov plua plav thiab ntxuav qhov chaw, thiab tsim nyog rau cov ntawv thov uas yuav tsum tau ua kom huv.
7. Bead blasting: - Bead blasting siv cov iav hlaws kom maj mam ntxuav thiab txhuam qhov chaw thiab tsim nyog rau cov chaw zoo xws li cov hniav nyiaj hniav kub thiab cov cuab yeej precision.
8. Dry Ice Blasting: - Kev ntxuav nrog cov dej khov qhuav qhuav tawm tsis muaj qhov seem thiab tsim nyog rau daim ntawv thov uas yuav tsum tau ntxuav cov khoom seem, xws li cov khoom siv ua zaub mov. Qhov kev xaiv ntawm cov txheej txheem blasting nyob ntawm seb hom khoom yuav tsum tau kho, qhov xwm txheej ntawm qhov chaw, lub hom phiaj ntawm cov txheej txheem thiab cov kev cai ib puag ncig. Txhua txoj kev blasting muaj nws tus kheej tshwj xeeb daim ntawv thov scenarios thiab qhov zoo, thiab kev xaiv kom raug ntawm blasting txheej txheem tuaj yeem txhim kho kev ua tau zoo thiab zoo ntawm kev kho deg.
