Photoetching hauv kev xyaum ua qauv
Daim duab-etched qauv. (Edward)
multimedia qauv? lo lus no yog hais txog cov khoom uas muaj cov khoom siv sib txawv. Cov neeg tsim khoom tau nce ntxiv cov hlau, resin, tshwj xeeb versions ntawm decals, thiab lwm yam rau cov qauv yooj yim ua los ntawm cov duab los qhia, ntoo lossis yas. Txhawm rau siv lawv kom raug, cov qauv tsim qauv yuav tsum ua kom pom cov txuj ci tsim nyog. Rau cov neeg uas xav kom muaj lawv, lub voj voog tom ntej yog mob siab rau.
Yees duab-etched
Cov txheej txheem ntawm kev tsim cov qauv tsim los ntawm cov yas tau raug txhim kho ntau thiab ntau dua. Txawm li cas los xij, txawm tias kev siv digital tsim ntawm kev txhaj tshuaj molding tuag yuav tsis tshem tawm qhov tsis zoo ntawm cov thev naus laus zis no? nws tsis tuaj yeem tsim cov khoom nyias nyias. Qhov no yog qhov pom tseeb tshaj plaws, piv txwv li, nyob rau hauv rooj plaub ntawm kev nthuav tawm cov ntawv nyias lossis cov ces kaum ntawm cov qauv tsheb. Ib qho 1 hli tuab ntawm 35: 1 nplai yuav ua tau 35 hli tuab. Nyob rau hauv qhov nrov tshaj plaws aviation nplai, 1:72, tib lub caij nyob rau hauv thawj yuav muab sib npaug rau 72 hli. Rau ntau tus qauv, qhov no tsis tuaj yeem lees txais, yog li, hauv kev sib zog ua kom haum rau tus thawj, lawv ua cov khoom me me los ntawm aluminium ntawv ci lossis tooj liab phaj. Qhov no yog vim qhov nyuaj ntawm kev ua haujlwm thiab kev sib dhos ntev. Qhov teeb meem no tau daws los ntawm kev qhia cov khoom lag luam (piv txwv li, Aber, Eduard) cov duab kos duab rau lub khw. Cov no yog cov phaj nyias, feem ntau yog ua los ntawm tooj dag lossis tooj liab, uas muaj cov ntsiab lus tseem ceeb tau muab tso rau hauv cov txheej txheem ntawm photolithography. Cov khoom tsim tawm, kuj pheej yig, tso cai rau txhim kho cov tsos ntawm cov qauv? hloov cov ntaub ntawv tsis raug lossis tsis raug rov tsim dua tshiab thiab ntxiv cov uas ploj lawm. Tau kawg, qee zaum kev ua yuam kev tshwm sim ntawm no, piv txwv li, muaj lub kauj tsheb hauv cov khoom siv (leej twg pom lub tiaj tus qub? kauj log ??!). Diam duab-etched ntsiab kuj tseem siv (thiab ntxiv) rau cov duab los qhia thiab ntoo.
Muaj ob pawg tseem ceeb ntawm cov khoom siv photoetch ntawm lub khw. Cov khoom siv ntau tshaj yog npaj rau cov qauv tshwj xeeb ntawm cov chaw tsim khoom no. Cov pab pawg thib ob muaj cov khoom siv thoob ntiaj teb, feem ntau siv rau hauv kev tsim kho ntawm dioramas. Yog li ntawd, peb muab cov rooj vag thiab wickets, barbed hlau, ntoo nplooj, txoj kev thaiv, cov paib, thiab lwm yam. Tag nrho cov khoom siv tau ntxiv los ntawm cov tuam ntxhab nrog cov lus qhia ntxaws: dab tsi thiab yuav ua li cas rau daim ntawv thiab qhov twg rau mount ntawm tus qauv.
Kev cob qhia thiab kev siv cov duab-etched ntsiab yuav tsum tau siv cov cuab yeej tsim nyog thiab cov txheej txheem ua. Tsim nyog kiag li? cov tweezers meej, riam ntse thiab cov cuab yeej uas peb tuaj yeem khoov cov nplooj ntawv. txiab, ib daim ntawv me me, ib lub iav loj, cov ntawv xuab zeb zoo, cov tho thiab rab koob ntse kuj tuaj yeem siv tau.
Diam duab-etched ntsiab yog sib sau ua ke rau hauv daim duab plaub. Cais tus kheej nrog ib rab riam, thaum lub phaj yuav tsum pw ntawm lub cushion nyuaj. Thaum tsis muaj ib lub hauv ob sab phlu, cov npoo ntawm cov khoom tuaj yeem khoov. Cov ntsiab lus tseem tuaj yeem txiav nrog txiab. Txawm li cas los xij, cov nplais hlau (qhov chaw nyob hauv lub phaj) yuav tsum raug txiav kom ze li sai tau rau qhov tsis muaj kev puas tsuaj. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ntawm cov khoom me me, cov loj loj tuaj yeem ua rau sanded ntxiv.
Tsim Diam duab-etching ntawm cov ntsiab lus yog qhov yooj yim heev vim tias lawv tau npaj kom zoo rau nws. Feem ntau, cov no yog etched, cov fragments uas yuav tsum muaj cov duab ntawm ib tug arc. Cov txheej nyias ntawm cov hlau ua kom yooj yim rau kev tsim. Nws yog qhov yooj yim tshaj kom tau txais cov khoom siv khoov siv? hoof yog li cas? laum ntawm txoj kab uas hla.
Cov chaw uas lub caij yuav tsum tau khoov ntawm lub kaum sab xis yog qhia los ntawm ib txoj kab nyias, uas yog etched. Cov khoom me me tuaj yeem khoov nrog tweezers. Cov loj dua yuav tsum muaj cov cuab yeej tsim nyog kom cov kab folding yog qhov sib npaug thiab sib npaug ntawm qhov ntev. Koj tuaj yeem yuav cov tshuab dabtsi yog khoov tshwj xeeb hauv cov khw muag khoom, uas yog qhov zoo rau kev tsim ntau hom ntev profiles, npog, thiab lwm yam. Nyob rau hauv cov ntaub ntawv ntawm cov ntsiab lus ntev heev, sab los yog rear ntug ntawm lub dabtsi yog khoov tshuab yog siv los kho. Lwm txoj hauv kev rau cov khoom kim heev no yog siv lub caliper. Nws cov meej thiab txawm lub puab tsaig tso cai rau koj tuav thiab khoov cov phaj feem ntau zoo kawg nkaus.
Embossing tau yooj yim rov tsim dua ntawm cov duab-etched ntsiab. Cov chaw tsim khoom puas tsim nyog, feem ntau yog oval, txiav hauv qhov chaw xaiv? lawv daim phiaj yog pom los ntawm ?sab laug? gills. Ua tus cwj mem (ntsuas nrog lub pob) rau hauv lawv, peb tsim protrusions. Thaum stamping, ib feem yuav tsum nyob rau ntawm ib qho nyuaj thiab theem saum npoo. Kev npaj cov embossing yuav me ntsis deform lub caij, maj mam kis nws nrog koj cov ntiv tes. Ib yam li ntawd, cov bulges loj tuaj yeem tsim, piv txwv li, hauv manholes rau tso tsheb hlau luam. Txhawm rau npaj lawv, siv lub pob me me los ntawm cov kabmob. Txoj kev zoo sib xws heev, yob lub pob nyob rau hauv qhov chaw trimming kom txog thaum tau txais cov duab uas xav tau.
Qee lub sij hawm nws tshwm sim tias daim ntawv siv los ntawm cov chaw tsim khoom yog ib qho nyuaj heev thiab, txawm tias cov undercuts, nws nyuaj rau tsim nws. Nyob rau hauv cov ntaub ntawv no, nws yuav tsum tau calcined tshaj ib tug roj burner thiab tso cai kom txias ntsiag to. Cov khoom uas npaj rau hauv txoj kev no yuav yog cov yas ntau dua.
kev teeb tsa Diam duab-etching ntawm cov ntsiab lus yog ua tau nyob rau hauv ob txoj kev: gluing nrog cyanoacrylate kua nplaum los yog soldering. Ob txoj kev muaj lawv qhov zoo thiab qhov tsis zoo. Gluing yog yooj yim dua, pheej yig dua, tso cai rau koj los txuas cov hlau rau yas, tab sis cov vuam tsis tshua muaj zog. Soldering yog ib qho nyuaj, kim dua, thiab nyuaj, tab sis cov khoom sib koom ua ke tuaj yeem tiv taus cov khoom hnyav. Qhov kev daws teeb meem no tsuas yog siv los txuas cov ntsiab lus hlau ua ke thaum muaj qhov loj (xws li fenders tank). Hauv kev xyaum, tus sau tsuas yog siv gluing, thiab qhov no, hauv nws txoj kev xav, yog ib qho kev daws teeb meem txaus. Tshwj xeeb tshaj yog vim nws muaj lwm qhov zoo dua? Cov ntsiab lus txuas nrog hauv txoj kev no tuaj yeem raug tshem tawm yam tsis muaj kev puas tsuaj rau lawv. Qhov thiaj li hu ua debonder (ib hom cyanoacrylate hnyav). Peb txo nws mus rau qhov chaw xaiv thiab tom qab ib pliag koj tuaj yeem ua tib zoo cais cov ntsiab lus. Txoj kev no peb muaj peev xwm kho qhov tsis zoo los yog cov khoom zoo li qub yam tsis tau rhuav tshem los yog khoov nws ntau dhau. Hmoov tsis, soldering tsis muab lub sijhawm zoo li no? ntawm qhov sib tshuam yuav ib txwm muaj cov seem ntawm cov tin.
Nws yog ib qho tseem ceeb heev uas yuav tau xaiv cov kua nplaum zoo. Qee qhov ua haujlwm sai dua, muab sijhawm rau koj tsawg dua los tso cov ntsiab lus kom raug, lwm tus txuas txuas qeeb dua, tso cai rau koj los kho tab sis ua kom qeeb tag nrho cov tsim. Lub ntsiab tseem ceeb thaum ua haujlwm nrog kev yees duab-etching? yog xaiv cov kua nplaum kom raug. Qhov me me dhau yuav qhuav sai thiab yuav tsis txuas cov ntsiab lus zoo. Ntau dhau ntawm nws tuaj yeem splatter, ntxuav tawm cov ntsiab lus me me (cov kua nplaum tom qab ntawd ua haujlwm zoo li putty) thiab tsim cov pob uas ua rau cov qauv ua kom puas tom qab pleev xim. Tab sis mloog? Koj tuaj yeem sim tshem tawm cov kua nplaum ntau dhau nrog tus debonder. Thiab thaum kawg, ib txoj cai ntxiv. Cyanoacrylate adhesives yuav tsum tsis txhob siv rau gluing pob tshab ntsiab, vim hais tias lawv tuaj yeem ua rau lawv pos huab, piv txwv li, tsim cov txheej txheej milky.
Thaum gluing, peb siv ib daim ntawv khi rau ib qho ntawm cov khoom sib koom thiab siv rau lwm qhov hauv qhov chaw xaiv. Cov nplaum yuav tsum tau kos (capillary) rau hauv qhov sib txawv ntawm lawv. Yog tias cov khoom me me heev, siv cov kua nplaum rau ib daim ntawm cov yas phaj thiab moisten cov npoo ntawm cov khoom uas tau ntes nrog tweezers hauv nws. Koj tuaj yeem koom nrog ob lub ntsiab lus sib txuas ua ke thiab siv cov kua nplaum rau ntawm qhov kawg ntawm rab koob.
Yog tias koj xav tau cov duab-etch qhov chaw, degrease lawv zoo. Koj yuav tsum siv cov tshuaj txhuam hniav (tsis muaj kua qaub!), thiab siv cov hlau uas tswj qhov kub thiab txias los yog cov pa roj microtorch kom sov cov ntsiab lus uas yuav tsum tau koom nrog. Nws yuav tsum nco ntsoov tias lub phaj, ua ntej overheated, annealed thiab them nrog ib txheej ntawm oxides, yog soldered heev capriciously.
Malovanie xav tau kev saib xyuas tshwj xeeb. Cov qauv nrog gills? lawv yuav tsum tau pleev xim nrog ib txheej nyias ntawm cov xim. Kev siv txhuam hniav tuaj yeem ua kom puas lossis tshem tawm cov khoom me me. Nws tseem tuaj yeem ua rau underpainting ntawm cov ces kaum ntawm bent sheet hlau.
