Vim li cas engineering thiab mechanical drawings xiav? Cov duab kos no yog xiav, nyob ntawm seb lawv kos li cas. Cov duab kos no tsis yog kos lossis luam tawm, tab sis "qhuav". Tej zaum nyob rau hauv txoj kev thiab txoj kev txhua lub sijhawm koj tuaj yeem pom qee qhov kos npe nrog cov duab tso rau ntawm lub qhov rooj ntawm qee lub khw luam ntawv, uas hais txog qhov no.
Cov ntawv luam ntawv, feem ntau hu ua "blueprint paper", yog ib hom tshuaj txheej ntawv, tshwj xeeb tshaj yog siv rau kev luam ntawv ntawm ntau yam engineering designs thiab machinery manufacturing. Nws yog ib qho khoom siv tseem ceeb hauv kev tsim khoom, kev tshawb fawb tshawb fawb, thiab kev tsim kho.
Blue architectural engineering drawings yog ib txoj kev kos duab loj uas tsim nyob rau hauv lub sijhawm ua ntej kos duab hauv computer.
Tus kws kos duab kos duab kos duab nrog tus cwj mem ntawm cov ntawv pob tshab hu ua "sulfuric acid paper". Lub hom phiaj yog los pab txhawb kev siv "lub tshuab luam ntawv" los luam tawm ntau cov duab kos zoo ib yam thaum siv ntau cov duab kos rau yav tom ntej.
Cov xim xiav ntawm daim duab yog tshwm sim los ntawm kev ua haujlwm ntawm ammonia fixation thiab rhiab heev ntawm "lub tshuab luam ntawv" thiab tsis muaj lwm lub ntsiab lus.
duab
Tam sim no, cov neeg siv kos duab tuaj yeem siv CAD los ua kom tiav ntau yam qauv kos duab es tsis txhob siv tes kos duab. Nyob rau tib lub sijhawm, thaum kos duab, lawv tuaj yeem siv lub plotter loj zoo li lub tshuab luam ntawv los luam cov duab kos hauv lub computer ntawm daim ntawv dawb. Muaj peev xwm luam tawm xim.
Txawm li cas los xij, txhawm rau luam cov duab tib yam hauv ntau qhov ntau, cov neeg tsim qauv tseem siv yav dhau los "txoj kev luam ntawv". Tus nqi kos duab ntawm txoj kev no yog tsawg heev. Tus nqi luam ntawv A {{0}} qhov loj ntawm daim duab rau hauv daim ntawv yog kwv yees li 0.80 yuan. Thiab nws ua tau zoo heev. Nws tsuas yog siv sijhawm li ob peb feeb los luam daim duab A1- qhov loj me rau hauv daim ntawv qhia.
Yog tias koj tsis xav kom daim duab yog xiav heev, koj tuaj yeem qeeb lub sij hawm nws yuav siv sij hawm los tshaj tawm cov duab kos; conversely, yog hais tias koj ceev lub sij hawm nws yuav siv sij hawm los tshaj tawm cov duab, nws yuav ua bluer.
Daim ntawv Blueprint (blueprint yaper) tseem hu ua daim ntawv ziab, thiab diazo ntsev yog ib yam li ntawv ziab los yog diazo photosensitive ntawv. Ib hom ntawv ua tiav ua los ntawm kev siv daim ntawv qhia dav dav raws li daim ntawv hauv paus, thiab tom qab ntawd txheej txheej ntawm daim ntawv qhuav nrog tus neeg sawv cev photosensitive. Nws yog yob ntawv.
Lub hauv paus ntawv yuav tsum muaj lub zog zoo ntub tensile thiab nqus cov khoom, tsawg deformation, thiab tsis muaj cov tshuaj uas cuam tshuam rau kev ua haujlwm ntawm cov khoom rhiab heev. Nws feem ntau yog ua los ntawm paj rwb pulp los yog bleached ntoo pulp ntawm lub tshuab ntawv. Blueprint daim ntawv ua los ntawm cov ntaub ntawv tsim nyog muaj cov yam ntxwv ntawm daim ntawv du, txheej txheej txheej txheej txheej, thiab tsis muaj pob dawb, me ntsis, tshuaj stains, wrinkles, thiab lwm yam.
Cov kev siv rau kev tshaj tawm cov duab kos muaj xws li:
1. Cov txheej txheem ntub dej kom qhuav, uas yog, cov duab kos dej-ntxuav, tseem hu ua hlau ntsev kos duab, uas nws photoreduction yog ntxuav nrog dej, thiab qee qhov tseem siv txoj kev no.
2. Dry printing drawings, uas yog, diazo additive drying drawings, los yog ammonia fumigation drying drawings. Lub photosensitive txo qhov system siv ammonia roj. Hom kev ziab khaub ncaws no yog muab rau hauv Suav teb.
3. Muaj ob hom kev luam ntawv semi-ntub. Ib qho yog siv cov photosensitizer thiab txo tus neeg sawv cev ntawm daim ntawv, thiab cov duab sib xyaw ua ke los ua ib daim duab. Tsis muaj txoj hauv kev zoo li no hauv Suav teb; lwm yam yog rau qhuav luam ntawv, nyob rau hauv uas ammonia yog evaporated thaum luam ntawv. Nws tsim cov huab cua kom nws tuaj yeem thaij duab thaum ziab.
Los ntawm kab xim, nws muab faib ua:
1. Cov kab xiav nyob rau hauv keeb kwm yav dhau dawb, kab dawb ntawm lub keeb kwm xiav xiav, thiab cov kab xim av ntawm cov keeb kwm dawb yog cov duab ntub dej qhuav.
2. Cov kab liab liab ntawm keeb kwm xiav, kab xim av ntawm cov keeb kwm dawb, thiab cov kab dub ntawm cov keeb kwm dawb yog cov duab kos duab qhuav. Hauv Suav teb, feem ntau ntawm lawv yog cov kab ntshav nrog cov keeb kwm xiav, thiab qee qhov chaw muaj kab xiav lossis kab dub nrog keeb kwm dawb.
Los ntawm txheej txheej: muaj ob hom: txheej txheej ib leeg thiab ob sab txheej:
1. Ib txheej txheej txheej muaj ob lub ntsiab lus: ib qho tsuas yog siv cov kua photosensitive rau ntawm daim ntawv siv; lwm qhov yog siv cov tshuaj photosensitive ntawm ib sab thiab boric acid dej ntawm lwm qhov kom tshem tawm cov warpage ntawm daim ntawv thiab txuas ntxiv lub sijhawm cia. Qhov tseeb, lawv yog coated ntawm ob sab. Vim hais tias tsuas yog ib sab yog photosensitive, lawv kuj hu ua ib leeg-sided coated khau. Feem ntau thaj chaw hauv lub tebchaws yog hom no.
2. Ob tog txheej txheej txhais tau hais tias thov tus neeg sawv cev photosensitive ntawm ob sab, thiab koj tuaj yeem luam cov duab ntawm ob sab. Qhov no tsuas yog txo cov ntim ntawm cov ntaub ntawv thiab txuag cov ntawv. Tam sim no, muaj 19 qhov chaw hauv Suav teb uas tsim cov duab kos duab, suav nrog Shanghai, Beijing, Tianjin, Hangzhou, Nanjing, thiab Wuhan. Txoj kev loj hlob ntawm cov xyoo tsis ntev los no yog cov keeb kwm dawb nrog cov kab xiav thiab ob txheej txheej, vim tias cov kab xiav luam ntawv yuav tsis hloov thaum lub sijhawm khaws cia. Hauv qab no, cov photosensitive ceev yog 1/5 sai dua li cov kab liab doog, thiab xim yog ci, thiab photosensitive ceev kam rau ua yog loj.
