Lub Luag Haujlwm Tseem Ceeb ntawm Dawb Fused Aluminium Sandblasting hauv Kev Kho Hlau Ua Ntej
Cov neeg uas ua haujlwm hauv kev lag luam no paub tias cov khoom siv hlau, zoo li tib neeg, xav tau kev npaj ua ntej mus ntsib cov qhua. Yog tias lawv raug roj, xeb, thiab xim qub, txhua tus yuav co taub hau. Kauj ruam thawj zaug hauv qhov "kev npaj" no yog kev kho ua ntej, thiab kev siv xuab zeb dawb fused aluminium yog qhov tseem ceeb hauv cov txheej txheem no. Niaj hnub no, peb yuav rhuav tshem nws thiab tham txog seb cov khoom siv no ua lub luag haujlwm tseem ceeb li cas hauv kev kho ua ntej hlau.
I. Tsis yog txhua "Xuab Zeb" yog Txhuas Dawb Sib Xyaws: Dab Tsi Ua Rau Nws Muaj Zog Ua Luaj?
Cov neeg tshiab rau hauv kev lag luam yuav xav tias kev xuab zeb tsuas yog siv xuab zeb los ntaus rau ntawm qhov chaw hlau xwb, nws muaj dab tsi tshwj xeeb txog nws? Zoo, qhov ntawd yog qhov kev xav tsis thoob. Sim siv xuab zeb dej lossis xuab zeb quartz? Cov khoom ntawd tsis tawv txaus, tsim ntau plua plav, tsis zoo rau kev noj qab haus huv ntawm cov neeg ua haujlwm, thiab feem ntau tso cov khoom seem rau ntawm qhov chaw tom qab blasting. Dawb fused alumina txawv; nws yog ib tus kws tshaj lij tiag tiag.
Xav txog nws:dawb fused aluminayog cov khoom siv corundum, ntshiab heev, thiab zoo li nws lub npe qhia, dawb huv. Tab sis nws nyuaj heev! Nws qhov nyuaj yog qhov siab tshaj plaws ntawm cov khoom siv abrasives, thib ob tsuas yog silicon carbide thiab pob zeb diamond. Qhov no txhais tau tias thaum nws cuam tshuam rau cov hlau nto, nws ua haujlwm zoo heev, txiav cov khib nyiab tangled nrog lub zog xob laim.
Ntxiv mus, nws ruaj khov heev hauv tshuaj lom neeg, tsis muaj silicon dawb, thiab nws cov hmoov av zoo dua rau lub ntsws. Nws tsim cov khoom me me sib npaug, tsis zoo li qee cov khoom siv abrasives uas tuaj yeem ua rau qhov tiav tsis zoo. Qhov tseem ceeb tshaj plaws, nws tsis nyiam hmoov av lossis av qias neeg; nws tseem huv si thiab yuav tsis muab cov khoom tsis huv rau hauv qhov chaw hlau, uas yog qhov txhawj xeeb tshaj plaws thaum thov cov txheej txheem lossis plating tom qab. Yog li ntawd, kev xaiv nws ua cov khoom siv thawj zaug muab kev thaj yeeb nyab xeeb.
II. Nws Txoj Kev Peb Txoj Kev: Kev Ntxuav, Kev Ua Kom Nruj, thiab Kev Ua Kom Muaj Zog
Kev tua hluav taws xob dawb fused alumina feem ntau tsom mus rau peb txoj kev ua ntej tseem ceeb: kev ntxuav, kev ua kom ntxhib, thiab kev txhawb zog. Cia peb tham txog lawv ib qho zuj zus.
Thawj Prong: Kev Ntxuav Kom Huv Si, Tsis Muaj Teeb Meem Tom Qab
Qhov no yog qhov yooj yim tshaj plaws, tab sis kuj yog qhov nyuaj tshaj plaws. Cov khoom hlau los ntawm lub Hoobkas hlau, lossis khaws cia rau hauv lub tsev rau khoom ntev, muaj qhov chaw uas yog "lub hnab sib xyaw" tiag tiag: oxide nplai (uas yog xiav lossis xim av liab), vuam slag, cov roj pleev xim tawv ncauj, cov txheej qub ... Kev ntxuav cov kua qaub tsis yog qhov ua tsis tau, tab sis nws tsis zoo rau ib puag ncig thiab tej zaum yuav ua rau lub substrate xeb. Kev sib tsoo tes nrog lub log hlau? Qhov ntawd tsis ua haujlwm zoo heev.
Kev tua alumina dawb fused tsis quav ntsej txog qhov ntawd. Los ntawm lub zog siab ntawm lub tshuab cua compressor, ntau lab tus me me dawb fused alumina me me, zoo li cov mos txwv, "whoosh," mus rau qhov chaw ua haujlwm. Qhov no tsis yog tsuas yog kev khaus xwb; nws yog ib qho txheej txheem stripping lub cev tiag tiag. Oxide nplai thiab vuam slag tsis yog dab tsi tab sis "ntawv tsov" nyob rau hauv nws lub xub ntiag, tam sim ntawd tawg thiab tev tawm. Tom qab txau, saib dua! Cov xim hlau ntuj tau tshwm sim, huv si thiab crisp, zoo li tofu ua tshiab - qhov pom zoo. Kauj ruam ntxuav thawj zaug no zoo li npaj ib daim "canvas" huv si rau cov txheej txheem tom ntej.
Lub Taub Thib Ob: Kev Ua Kom Roughening Zoo Kawg Nkaus, Tuav Lub Txheej Txheej
Puas yog kev ntxuav txaus lawm? Tsis txaus li! Xav txog ib qho chaw hlau du, zoo li daim iav; yog tias koj tsuag xim lossis hmoov pleev xim rau nws, puas yuav ua rau nws lo zoo? Nws zoo li muab ntawv xov xwm lo rau ntawm iav - nws yuav poob tawm ntawm qhov kov me ntsis. Qhov xav tsis thoob thib ob ntawm kev siv xuab zeb dawb corundum yog "ua kom ntxhib" qhov chaw du no.
Nws tsis ua puas tsuaj, tab sis theej "sculpts." Nws tsim ntau qhov me me, sib xws ntawm qhov chaw hlau, uas peb hu ua "anchor patterns" lossis "roughness." Tsis txhob saib tsis taus cov qhov no; lawv ua rau thaj chaw ntawm qhov chaw ntau ntxiv, zoo li muab cov txheej txheem nrog ntau txhiab tus "tes me me," tuav nws ruaj khov. Qhov no ua rau muaj kev nce geometric hauv kev sib txuas ntawm cov xim pleev xim thiab txheej yas, ua rau nws tsis yooj yim tev tawm lossis tawg. Qhov cuam tshuam roughening no, ntsuas nrog cov cuab yeej tshaj lij ua "roughness," yog ib yam dab tsi uas tus kws ua haujlwm paub dhau los tuaj yeem qhia tam sim ntawd los ntawm kev kov: "Hmm, txoj haujlwm no ua tiav zoo, cov xim lo rau zoo!"
Kauj Ruam Thib Peb: Kev Ua Kom Muaj Zog Tsis Pom Kev, Ua Kom Lub Neej Ntev Dua
Kauj ruam thib peb no zoo li "lub zog sab hauv" - tsis pom thiab tsis pom, tab sis cov txiaj ntsig yog qhov tseeb. Qhov cuam tshuam ceev ceev ntawm cov khoom dawb corundum rau ntawm qhov chaw hlau yog qhov tseem ceeb me ntsis "ua haujlwm txias". Nws ua rau muaj kev cuam tshuam ntawm cov hlau, tsim kev ntxhov siab compressive.
Kev ntxhov siab compressive yog dab tsi? Xav txog nws zoo li no: nws zoo li muab "lub cev tsis pom" rau ntawm qhov chaw hlau, ua rau cov khoom siv molecular qauv compact thiab robust. Qhov no ua rau cov hlau lub zog qaug zog thiab txhim kho nws txoj kev tiv thaiv kev ntxhov siab corrosion, ua kom ntev lub neej ntawm cov workpiece. Rau qee qhov tseem ceeb, xws li cav crankshafts thiab dav hlau tsaws iav, cov txheej txheem no yog qhov tseem ceeb tshaj plaws.
III. Qhov zoo ntawm txoj haujlwm nyob ntawm seb koj siv nws li cas
Cov khoom siv nws tus kheej tej zaum yuav zoo, tab sis kom ua tiav txoj haujlwm tau zoo, nws nyob ntawm seb koj siv nws li cas. Muaj ntau yam tswv yim rau nws.
Ua ntej, koj yuav tsum xaiv cov xuab zeb zoo. Cov xuab zeb ntxhib muaj nws cov kev siv, thiab cov xuab zeb me me muaj nws cov kev xav txog. Yog tias koj xav tshem tawm cov xeb tuab lossis xim, koj yuav tsum siv cov xuab zeb ntxhib dua, xws li 20 lossis 30 mesh, kom muaj zog dua. Yog tias koj tsuas xav tau kev ntxuav zoo lossis cov qauv anchor zoo heev, koj yuav tsum siv cov xuab zeb me dua, xws li 80 lossis 100 mesh. Koj siv tsis tau tib cov xuab zeb rau txhua yam.
Qhov thib ob, koj yuav tsum tswj lub zog cua thiab lub kaum sab xis. Yog tias lub zog cua qis dhau, cov khoom siv abrasive yuav mos thiab tsis muaj zog; yog tias lub zog cua siab dhau, nws tuaj yeem yooj yim ua rau cov khoom ua haujlwm nyias nyias lossis txawm tias tawg cov khoom siv abrasive, ua rau cov txiaj ntsig tsis zoo. Tib yam siv rau lub kaum sab xis ntawm rab phom txau. Rau kev ntxuav ib txwm, lub kaum sab xis ntawm 45 txog 70 degrees yog qhov tsim nyog tshaj plaws. Yog tias lub kaum sab xis me dhau, nws zoo li "khawb hauv av," ua rau cov txiaj ntsig tsis sib xws.
Thaum kawg, qhov chaw ib puag ncig yuav tsum tau khaws cia kom qhuav.Dawb fused aluminazoo heev rau txhua txoj kev, tsuas yog nws me ntsis "rhiab rau cov dej noo." Thaum nws ntub lawm, nws yooj yim sib sau ua ke, txhaws lub qhov txau tshuaj tsuag, uas tuaj yeem ua rau qeeb heev. Yog li ntawd, peb qhov chaw tso cua yuav tsum muaj lub tshuab cais roj-dej, thiab lub tank cia xuab zeb kuj yuav tsum tau tiv thaiv kom tsis txhob ntub.
Yog li, thov tsis txhob xav txog alumina fused dawbkev xuab zebua ib txoj haujlwm "ntxuav" yooj yim. Hauv kev kho hlau ua ntej, nws yog ib qho khoom siv uas ua tau txhua yam, ua haujlwm ua "tus ntxuav," "tus kws kos duab," thiab "tus neeg sawv cev txhawb zog." Nws tsim cov txiaj ntsig huv, sib xws, thiab nplaum zoo, thiab nws kuj "txhawb zog" cov khoom hlau, tso lub hauv paus zoo meej rau cov txheej txheem tom ntej xws li txau, electroplating, thiab vuam. Hauv kev ua haujlwm hauv kev lag luam, peb ntseeg tias "lub hauv paus tsis muaj zog ua rau tsis ruaj khov." Qhov kev kho ua ntej no yog "lub hauv paus" rau txhua txoj haujlwm zoo nkauj. Kev siv cov xuab zeb dawb fused alumina kom raug yuav zoo li yog ib kauj ruam ntxiv hauv cov txheej txheem, tab sis nws yeej txuag tau nyiaj ntau ntawm kev ua haujlwm dua thiab kho tom qab. Nws yog kev lag luam tsim nyog txawm tias koj saib nws li cas los xij! Nws zoo li tus nyuj laus uas ntsiag to tab sis ntseeg tau heev hauv kev kho hlau ua ntej, yeej tsis ua rau koj poob siab thaum nws tseem ceeb tshaj plaws.
