Vim li cas cov kev ua tshuab engineering thiab tshuab kos xiav xiav? Cov duab kos no xiav, uas cuam tshuam nrog lawv cov qauv kos duab. Cov duab kos no tsis tau kos lossis luam tawm, tab sis "raug". Tej zaum koj tuaj yeem pom qee lub tsev luam ntawv nrog cov cim xws li "muab cov duab kos" muab tso rau ntawm lub qhov rooj ntawm txoj kev thiab kev tag nrho, uas yog hais txog qhov no. Kev txiav tawm duab feem ntau yog hu ua "Blueprintics", uas yog hom kev tsim tshuaj thiab tshuab siv tsis tau muaj nyob rau hauv kev tsim khoom, kev tshawb fawb, kev tshawb fawb, thiab kev tsim kho. Xiav cov kos duab kos duab xiav yog qhov teeb meem kos duab loj tsim nyob rau hauv lub sijhawm ntawd yam tsis muaj teeb duab kos. Draftsmen kos cov duab kos nrog cov ntawv penbon pen ntawm pob tshab ntawv hu ua "sulfuric acid ntawv". Lub hom phiaj yog los pab txhawb kev siv "kev siv tshuab" los tsim cov duab kos ntau yam thaum cov duab kos tau siv rau yav tom ntej. Cov xim xiav ntawm cov duab kos yog vim yog txoj cai ua hauj lwm ntawm ammonia kev ua haujlwm thiab cov duab ua haujlwm ", thiab tsis muaj lwm lub ntsiab lus.
Nyob rau tam sim no, qauv sau tuaj yeem siv CAD txhawm rau ua tiav daim duab ntawm ntau yam txheej txheem kos duab yam tsis muaj kev kos duab. Nyob rau tib lub sijhawm, thaum kos duab, lawv tuaj yeem siv tus loj plotter zoo li lub tshuab luam ntawv kom luam tawm cov duab hauv lub computer, lossis sau lawv cov xim dawb.
Txawm li cas los xij, txhawm rau luam cov teeb duab tib yam hauv cov khoom loj, cov neeg tsim qauv tseem siv cov qauv qub ". Txoj kev no muaj tus nqi nqus tau tsawg heev. Tus nqi ntawm luam ntawv ib qho {{{{0}} qhov loj me kos rau hauv daim duab yog hais txog 0.80 Yuan. Thiab nws yog qhov ua tau zoo heev. Nws tsuas siv sijhawm li ob peb feeb los luam tawm ib qho 1- qhov me me kos rau hauv daim phiaj.
Yog tias koj tsis xav tau daim duab yuav tsum xiav heev, koj tuaj yeem qeeb lub sijhawm luam ntawv; Ntawm qhov tsis sib xws, lub sijhawm nrawm dua rau lub sijhawm luam ntawv, lub bluer nws yuav.
Daim ntawv qhia txog daim ntawv qhia txog daim ntawv qhia yog tseem hu ua cov ntawv luam ntawv, thiab cov ntaub ntawv diazonium zoo li ntawv luam ntawv lossis diazo photosensitive ntawv. Ib hom ntawm cov ntawv sau ua los ntawm kev siv cov ntawv npog xiav ua ke raws li daim ntawv ntim cov ntawv sau nrog cov ntawv sau ua ke nrog cov ntaub ntawv yob.
Lub hauv paus ntawv yog yuav tsum muaj cov khoom ntub zoo ntub lub zog thiab nqus cov khoom ntiag tug, thiab tsis muaj tshuaj lom neeg uas cuam tshuam rau cov khoom siv rhiab. Nws feem ntau yog ua cov paj rwb puab lossis cov ntoo ua kom dawb huv rau ntawm lub tshuab papermaking. Daim ntawv qhia txog daim ntawv uas tsim muaj los ntawm cov ntawv pov thawj ntawm cov ntawv du, tsis muaj cov pob me, cov tshuaj, yeeb tshuaj steelles thiab wrinkles.
Muaj ob hom ziab kom haum raws li txoj kev siv:
1 Qhov kev txo cov duab ntsej muag yog ntxuav nrog dej, thiab qee cov chav nyob tseem siv hom no.
2
3. Muaj ob hom semi-ntub dej qhuav kos duab. Ib hom yog siv ob qho tib si tus neeg saib xyuas tus neeg saib xyuas thiab tus neeg sawv cev txo tus neeg sawv cev ntawm daim ntawv, thiab kos duab txuas rau thaum raug teeb. Tsis muaj ib txoj kev zoo li no nyob hauv Suav teb; Lwm hom siv rau kev ziab qhuav. Thaum ziab, dej ammonia yog evaporated rau hauv pos huab, yog li ntawd qhov kev kos duab yog tsim thaum ziab.
Raws li cov xim ntawm cov kab, muaj:
1. Cov kab xiav nyob dawb tom qab, dawb kab ntawm xiav keeb kwm yav dhau, thiab cov kab xim av nyob dawb tom qab, uas ntub dej kom qhuav drawings.
2. Ntshav kab ntawm xiav keeb kwm yav dhau, kab xim av nyob dawb tom qab, thiab cov kab dub nyob dawb tom qab, uas tau qhuav qhuav kos duab. Tam sim no, feem ntau ntawm cov kab hauv tsev yog cov kab paj rau xim xiav, thiab qee thaj chaw muaj cov kab xiav lossis dub nyob dawb tom qab.
Los ntawm txheej txheej txheej: Muaj ob hom: ib sab txheej thiab ob tog txheej txheem:
1. Ib leeg ib leeg txheej muaj ob lub ntsiab lus: ib qho yog los siv cov kua kws ua kua tsuas yog siv rau hauv kev siv; Lwm tus yog los ua cov neeg saib xyuas tus neeg saib xyuas ntawm ib sab thiab boric acid dej nyob rau lwm sab los tshem tawm ntawm warping ntawm daim ntawv thiab nce lub sijhawm cia. Nws yog tiag tiag ob sab ib sab txheej. Vim tias tsuas yog ib sab yog cov duab, nws tseem hu ua ib nkawm khau ib leeg. Feem ntau ntawm lub teb chaws yog ntawm hom no.
2. Ob leeg sab ib sab yog los thov tus neeg saib xyuas cov duab ntawm ob sab, thiab ob sab tuaj yeem luam tawm. Nws yog feem ntau yog los txo cov ntim ntawm cov ntaub ntawv thiab txuag daim ntawv. Txoj kev kawm nthuav dav nyob rau xyoo tsis ntev los no yog cov kab laum tom qab, thiab cov xim nrawm dua li cov kab mob tsis hloov chaw, thiab cov xim xiav thiab lub siab ntev ntawm cov duab ceev yog loj.
