Flexographic printing, offset printing, gravure printing thiab screen printing yog plaub txoj kev luam tawm, txhua tus uas muaj nws txoj hauj lwm zoo. Tam sim no, lub lag luam thiab luam ntawv kev lag luam yog tsim nyob rau hauv kev coj ua ntawm siab zoo, fineness thiab diversification. Txawm li cas los, qhov kev faib tawm ntawm kev lag luam luam tawm thiab gravure luam ntawv yog loj, thiab flexo printing pib hauv Suav teb, tshwj xeeb tshaj yog hauv high-quality printing. Txawm li cas los xij, nrog daim ntawv thov tshiab ntawm kev yees duab tshiab, qhov tshwj xeeb thiab cov haujlwm loj tshaj tawm tau zoo ua tau zoo thiab muaj kev sib tw ua lag luam zoo heev.
Cov khoom siv luam tawm thiab tshuab luam ntawv yog qhov tseem ceeb ntawm tag nrho cov ntawv luam tawm flexographic, uas yuav qhia txog cov khoom siv luam ntawv, kev xaiv khoom, kev tsim ua haujlwm thiab cov qauv kev ua haujlwm. Kev khiav dej num ntawm txhua txoj hau kev yog ib qho tseem ceeb rau tus neeg teb xov tooj.
Kev sib lawv liag ntawm kev ua haujlwm yog raws li nram no:
Pub yob → noj cov ntawv nyeem → kev kho thiab kho qhov sib txawv → kev sib txeeb anilox → txav sab nraud → kev kho siab → khoob khoob khesxaws → ntawv pov thawj → nrawm tswj → khaus tshuab → tuag taus → txiav ntoo
Pub yob
Tom qab kev thauj khoom ntawm lub yob, qhov chaw ntawm lub yob tseem yog qhov chaw luam ntawv, vim hais tias cov kev nplua lus, kev tuag, kev sib faib, thiab lwm yam yog tag nrho raws lub hauv paus loj, thiab cov ntawv luam tawm yuav tsum ncaj qha raws li daim ntawv pub rau lawv ntawm cov khoom. Tom qab txhua tus neeg pub mis rau menyuam noj thiab daim ntawv pub mis, lub tshuab tuaj yeem pib ua kom daim ntawv xa tawm kom zoo, kho qhov tsis sib haum, thiab cov ntawv luam tawm raug rau ib qho kev sib sib zog yooj yim kom paub tseeb tias qhov kev txiav txim siab tshaj, kho qhov sib txawv , thiab ua cov khoom nyob hauv nruab nrab ntawm cov tshuab luam ntawv thiab cov ntawv phaj. Txoj hauj lwm los xyuas kom meej tias txoj kev kho kom haum yog rhiab.
Kho siab
Kev hloov ntawm lub tshuab luam ntawv flexographic yog ib qho tseem ceeb ntawm cov khoom siv, uas cuam tshuam ncaj qha rau qhov ua tiav ntawm cov khoom luam tawm. Qhov kis ntawm cov phom luam ntawv thiab tus menyuam nyaum kab npab yog tib yam. Lub 2.08mm (1.7 phaj + 0.38 ob tog sided) yog xaiv tau. Tus qauv feeler gauge ntawm lub thickness ntawm daim kab xev ua tus tsis kam ntawm lub feeler duas ntawm ob xaus tib yam. Lub zais ntawm lub sij hawm no yog qhov tseem ceeb tshaj plaws rau cov nqi luam ntawv (tab sis nyob rau hauv cov khoom tiag tiag, tus neeg teb xov tooj yuav tsum tau ceev faj zoo-tuning, ces tus kws kho mob xav tau Cov tswv yim tsim kom tau qhov zoo tshaj plaws ntawm tus nqi siab).
Hauv qab qeeb khiav ntawm lub tshuab, lub siab pib ntawm cov thawj xim pawg. Ua ntej, tus lej hloov ntawm tus menyuam yaus rau lub phaj rau cov menyuam. Lub kaw lus siab ntawm ob hnub yuav raug kho rau qhov zoo tshaj plaws cov nyhuv. Lub siab ntawm ob lub thawv yog lub teeb. Zoo, nws yog ib qho zoo rau lub qub txav ntawm cov ntaub ntawv network, los xyuas kom meej ntawm cov duab thiab kev tiv thaiv ntawm lub phaj. Qhov thib ob, qhov kev sib kho siab ntawm cov phom thiab cov tub ntxhais muaj kev sib raug zoo yog pom, thiab qhov kev hloov ntawm qhov kev hloov yog pom, thiab qhov kev pom tseeb ntawm cov ntaub ntawv luam tawm ntawm cov khoom muaj tseeb los ntawm qhov tseeb ntawm qhov hloov ceev (ceeb toom: kauj ruam yog hloov raws li kev paub ntawm cov kws kho mob). Nws yog qhov yuav tsum tau kov yeej lub siab tshaj ntawm cov ntawv luam tawm, uas yog tus yuam sij rau cov ntawv phaj. Tension tswj system
Tswj lub nro qhov nro ntawm lub nruas xws li thaum lub sij hawm luam ntawv yog tus yuam sij rau txoj kev tshaj tawm. Yog li no, qhov kev tswj nruj yog qhov tseem ceeb ntawm txhua lub vas sab, uas yog txiav txim siab txog kev luam ntawm cov luam ntawv kom loj. Lub nrooj tswj mechanism yog tsuas yog nyob rau hauv qhov chaw tawm, qhov chaw nres tsheb luam ntawv thiab traction thiab kev tuav pov hwm cov cuab yeej ntawm cov khoom txais, qhov tso tawm ntawm cov khoom siv yob xav tau, kev sib hloov ntawm cov khoom siv yob muaj inertia, thiab cov khoom siv xwb muaj ib qho nqi nro, ntxiv nrog rau kev luam ntawv. Kev thawb tawm, qhov tsis kam ntawm txhua pab pawg neeg xim zoo nkauj tshaj rau cov ntawv luam thaum lub sijhawm luam ntawv ua rau lub nro tswj ntawm qhov kev sib tawm tsam, kev luam ntawv thiab kev sib tw mechanism tshwj xeeb. Qhov loj ntawm lub nro tswj yuav tsum tau txiav txim siab raws li lub thickness ntawm cov khoom thiab qhov dav ntawm cov khoom. Lub thicker cov khoom yuav tsum muab luam tawm, qhov ntau dua qhov muaj nqis nro; qhov sib txawv ntawm qhov kev nruj yuav tsum yog me me, xws li qhov muaj nqis ntawm cov ntawv luam tawm ntau dua, vim tias qhov teeb meem ntawm kev ntsws, rhuav tshem, thiab lwm yam ntawm cov ntawv luam tawm yuav tsum tau muab coj los rau hauv tus account, thiab qhov kev hloov nrawm li feem ntau yog xam. Nws yog los ntawm ntau qhov xim "cross txoj kab kab", thiab tsis "txav" rov los ua tus qauv. Yog tias qhov "cross line" overprinting tsis ruaj khov thaum lub sij hawm luam ntawv, qhov nro ntawm qhov kev sib tawm thiab kev sib tw yuav raug kho kom haum raws li cov xim pawg "crosshairs" Daim ntawv sau npe ruaj khov, qhov tseeb, qhov nqi zog tsis zoo ib yam nkaus thaum qis qis , nruab nrab ceev thiab siab ceev thaum luam ntawv. Nws raug nquahu kom nplua-tune muaj nqis ntawm qhov ceev, thiab qhov tshwm sim ntawm "taug kev" feem ntau tshwm sim thaum lub sijhawm luam ntawv. Cov neeg siv los saib rau khoom, khoom thiab lwm yam. Qhov tseeb, nws tsis yog qhov nruj uas tsis xis nyob. Yog tias koj ua tib zoo kho qhov nro, feem ntau, tsis muaj cai los daws qhov teeb meem.
Kev kho ntawm pH thiab viscosity ntawm number case
Txuj kev tswj cov pH thiab viscosity ntawm tus number case thaum lub sij hawm luam ntawv yog lub ntsiab ua haujlwm tseem ceeb los xyuas kom zoo ntawm cov khoom luam tawm.
Cov pH ntawm cov dej uas muaj kua dej yog li 8.5. Ntawm no tus nqi, tus number case no kuj ruaj khov, tab sis nyob rau hauv ntau lawm, raws li qhov kub nce thiab ammonia nyob rau hauv tus number case evaporates, pH nqi hloov, uas cuam tshuam cov luam ntawv zoo ntawm tus cwj mem. Ib qho me me ntawm stabilizer tuaj yeem raug ntxiv los tswj tus nqi pH. Hauv ib txwm luam, nws feem ntau yuav tsum tau ntxiv 5 ml ntawm stabilizer txhua txhua ib nrab teev thiab do nws tusyees. Yeej, cov roj dub tuaj yeem ua kom ruaj khov haum tsim nyog. Ntxiv cov stabilizers, txwv tsis pub nws yuav thuam thiab ntau yam teeb meem luam tawm yuav ua raws li.
Lub xauv npo ntawm tus cwj pwm yog qhov tseem ceeb tshaj plaws uas yog txiav txim siab txog kev muab cov ntaub ntawv tseem ceeb, luam tawm ceev ceev, nkag mus thiab ci ntsa iab. Tus cwj pwm viscosity ntau dhau, xim dua ib tsos kob, ntau dua qhov poob ntawm tus cwj pwm, qeeb qeeb ntawm qhov ziab, zus cov viscosity, ntau dua cov xim hloov, thiab qhov ntsuas loj dua, ua rau poob qis zoo.
Cov kaus mom hlau dej muaj viscosities txawv thaum luam txheej thiab tag nrho cov ntawv. Qeb hoob kos viscosity yuav tsum qis me ntsis. Thaum lub sij hawm luam ntawv, qhov ceev ntawm lub tshuab kuj muaj cov nyhuv rau ntawm tus cwj mem kua viscosity. Thaum lub siab ceev luam ntawv siab siab, tus cwjpwm ntawm cov dej-raws li qis dua, thiab tus cwj mem ntawm viscosity ntau dua thaum luam ntawv qis qis dua.
Tuag txiav chaw nres tsheb
Yuav kom tham txog lub tshuab luam ntawv flexographic luam ntau yam, ntxiv nrog rau cov kev ua haujlwm hais saum toj no rau ntawm cov txheej txheem kev luam ntawv, kuv xav tham txog qhov teeb meem tuag qhov chaw nres tsheb ntawm qhov nqaim luam ntawv. Vaub-nplai flexographic luam ntawv feem ntau muaj peb qhov kev txiav tuag. Tom qab luam ntawv, lawv indented thiab tuag-txiav kom tau txais cov khoom luam yam xav tau. Lawv tuaj yeem siv rau kev zauv, cov ntaub ntawv, cov hnab tshuaj, thiab lwm yam. Yog tias siv hlau nplaum feem ntau, cov hlau nplaum hlau ntawm ntau yam khoom siv yuav tsum tau npaj los ua ib qho kev ua tiav, uas tuaj yeem ua raws li kev txiav tawm ntawm feem ntau cov khoom sib txawv. Ua cov txheej txheem.
Lwm qhov kev tuag ntuag yog hu ua ib zaug xwb. Nws yog ib rab riam uas tau muab tso rau hauv lub taub hau ntawm lub taub hau. Ib qho, ob, plaub los sis ntau tshaj ntawd yuav qhib tau yog tias xav tau. Nws yog tsuas yog siv rau kev txiav ib cov khoom tiav. Qhov txiav ib yob tuaj yeem ua qhov loj tib yam li cov phaj yob. Los yog siv ob zaug.
Tus plawg txheej daus sab nraud yuav tsum tau nruab nrog ib daim ntawv daim txhuam cev ua ntej siv los txhawm rau txhawm rau kev txiav txim siab thiab tsis txhob raug rau riam ntug. Lub siab yog kho kom cia li txiav tawm cov khoom luam tawm rau kev siab ceev.
Tsis tas li ntawd, them nyiaj rau tom qab-nias xa, glazing, laminating, bronze, xuas nrig, thiab lwm yam.
Cov tshooj no piav me ntsis txog cov tswv yim luam tawm thiab kev ua haujlwm ntawm flexo printing, vam tias yuav ua ib qho kev siv rau cov ntawv luam ua flexographic luam, cov ntaub ntawv hloov tshiab, cov ntawv luam tawm tsis muaj qauv siv rau kev siv. Nws tau vam tias cov neeg ua haujlwm luam ntawv yuav xyaum thiab sib txeeb cov kev ua hauv kev tsim khoom.
