Hauv txhua txhua lub neej, peb tuaj yeem pom cov duab thev ntim txhua qhov chaw. Txoj kev xav tau cov ntaub ntawv sau ntaub ntawv ntau yog siv rau xim luam ntawv. Yuav kom tsim cov duab yeeb yaj kiab uas muaj kev sib tw, sib txawv ntawm ntau cov ntaub ntawv yuav tsum muaj-kev sib raug zoo ntawm cov khoom cua, cov hnyiab, thiab cov roj luam ntawv.
Ib lub lag luam loj hlob
Nyob rau xyoo tas los no, tag nrho cov nqi ntawm cov khoom ntim tau yooj yim tau nce, uas qhia tau dav dav ntawm cov ntawv yoojyim los hloov cov khoom ntim xws li iav fwj thiab cov hlau poom. Qhov no tsis yog vim nws txoj kev siv nyiaj ntau, tab sis vim tias nws tuaj yeem hloov kho hauv kev lag luam kom sai dua thiab zoo dua. Kev nce ntau txheej txheem txheej txheem (txheej txheem 3-txheej thiab plaub-txheej) nws ua raws li qhov kev nthuav dav-nthuav dav thiab muaj ntau yam kev xav tau ntxiv. Kev lag luam zaj yeeb yaj kiab tuaj yeem muab faib ua peb qho: kev lag luam tawm tom khw rau cov khoom ua kua: qhov nruab nrab ua lag luam rau ntim cheese, tshiab nqaij, thiab lwm yam., Lossis lub khw muag khoom tsawg tsawg rau cov khoom xws li cov khoom noj sai.
Txhim kho cov duab yeeb yam
Los ntawm kev sib cuam tshuam ntawm cov khoom sib txawv hauv zaj duab xis composite, qhov zoo ntawm txhua txheej yog sau. Cov nram qab no yog cov haujlwm ntawm zaj yeeb yaj kiab:
1. Dej vapor barrier tiv thaiv kom tsis ntub khoom los ntawm kev ziab thiab siv cov ntaub ntub dej txias: tiv thaiv cov khoom muag qhuav ntawm cov dej noo, xws li cov khoom ci thiab cov khoom ua hmoov.
2. Acidic teeb meem. Txwv tsis pub oxidation xws li roj thiab cov khoom tshiab.
3. Cov kab mob carbon dioxide thaiv. Tivthaiv cov pa roj carbon dioxide poob hauv cov phom MAP Cov dej khov ruaj khov yog cov dej haus.
4. Aroma thaiv. Tus ntxhiab tsw tiv thaiv tsis tau evaporate ntawm pob thiab loses, xws li kas fes.
5. Cov ntxhiab tsw. Tiv thaiv kev quav ntawm lwm cov ntxhiab tsw los yog tiv thaiv tsis tau cov ntxhiab tsw.
6. Teeb thaiv qhov muag. Tiv thaiv cov oxidation ntawm lub teeb xws li cov khoom noj siv mis.
7, lub foob yeej ruaj khov. Rau lub sealing ntawm zaj duab xis composite, tshav kub sealing yog siv.
Cov yeeb yaj duab Aluminized muaj qhov teeb meem zoo tshaj plaws. Vaporization ntawm cov hlau mus rau tus yeeb yaj kiab hlau yas kuj muab cov khoom uas nyob ze rau ntawm cov ntawv ci txhuas. Kev siv cov txhuas sulphate los yog silicon oxide vaporized rau tsiaj los yog OPP yas txha hniav muaj peev xwm kuj muaj kev tiv thaiv zoo. Tab sis tsis muaj ib qho teeb meem zoo ntawm lub teeb nris.
Txhim kho zaj duab xis
Ib zaj duab xis uas tsim los ntawm ob los yog ntau cov khaubncaws sab nraud povtseg yuavtsum yog raws li ib zaj yeeb yaj kiab. Qhov no yuav tsis tsuas yog tus neeg sawv cev ntawm qhov drilling nruab nrab ntawm ob zaj duab xis, tiam sis tus cwj pwm xiam. Drilling Agents yog Khoom Sib Nqus Cov feem ntau cov twj drilling yog ob qho uas siv cov tshuaj Polynitrous urethane (PU). Cov tshuaj tiv thaiv ntawm cov txheej txheem drilling cures compound drilling. Tus neeg sawv cev ntawm tus nplhaib ntawm tus npoo ntawm cov substrate mas yog kev siv lub cev. Tsuas yog ib feem me me yog txheej txheem tshuaj. Nyob rau lub sij hawm no, lub tshuab ntawm qhov drilling yog drilled ua ke nrog cov khoom nyob rau hauv cov yas zaj duab xis thiab ntxiv kho.
Yog tias ib zaj yeeb yaj duab twb tau luam tawm thaum lub txheej txheem drilling, tus neeg ua hauj lwm thiab tus cwj pwm xaj yuav tsum tau ua raws li cov cai ntxiv. Qhov kev xav tau yooj yim tshaj plaws yog kom muaj kev nplua zoo thiab ua kom qhuav txhua qhov hauv txheej txheej ua ntej kev sib koom tes. Qhov no yog qhov ntau qab. Tsis muaj cov khoom seem uas yog tso rau hauv cov ntawv luam tawm. Txawm li cas los xij, cov tshuaj cawv los yog cawv feem ntau nyob hauv cov thev npog tus lej. Vim li no, qhov kev ua tiav ntawm qhov drilling compound yuav tsum tau ua ke nrog cov dawb radicals (-OH pawg). Yog tias tsis yog, tus neeg tsav tsheb thiab tus neeg sawv cev ntawm tus neeg ua haujlwm yuav ua rau qhov kev tsis sib haum xeeb kom poob qhov xwm txheej uas lawv yuav tsum muaj. Piv txwv, hauv zaj yeeb yaj kiab tau muab luam tawm nrog PVB number case, thiab ntsev nyob hauv tus cwj mem, thiab cov tshuaj hauv paus "NCO pab pawg" ntawm ntsev reacts nrog cov dawb radical-OH ua ke ntawm dej cawv thiab dej. Tsis muaj residue tshwm sim hauv cov teeb meem tsis txaus los ntawm tus neeg ua hauj lwm drilling. Yuav ua li cas raws li yog ib qho kev kho tsis txaus thiab ua tau.
Ntawm cov neeg ua hauj lwm drilling, cov hnyav los ntawm cov hnyav yog qhov txawv ntawm qhov hnyav hnyav xws li UV kev siv. Qhov hnyav raws li yuav tsum tau siv qhov ziab kom qhuav kom qhuav ntawm tus neeg sawv cev. Thaum siv tus UV drilling compound, UV lub teeb kis tau los ntawm cov yeeb yaj kiab kom mus txog qhov chaw tso dej ntawm lub qhov dej ua rau ua tus neeg sawv cev ua ke mus rau polymerize ua ke.
Lej rau cov zaj duab xis
Cov cwj mem tsis zoo rau zaj yeeb yaj kiab tsis yog tsuas yog muaj kev zoo nkauj ntawm ntau cov yeeb yaj duab (OPA, OPP, PET-ALOX, PET-SiOX, PE, Alu), tab sis kuj tag nrho mus nrog tus neeg ua hauj lwm rau drilling thiab muaj zog. Internal cohesion (cohesiveness ntawm tus number case) thiab kev tiv thaiv tsis yog tshuaj yog tseem ceeb heev. Ntxiv cov kev cai rau cov zaj duab xis zaj duab xis roj yog: ntev-ntev qauv luam ntawv, sterility thiab yooj yim stamping thiab zoo nkauj xim kho nrog cov kauj nrhua sai nrhav.
Rau kev sau zaj duab xis luam. Nitrocellulose (NC), poly-p-butene (PVC), polyethylene drunk butyral (PVB) nitrocellulose arsenic-polyurethane (NC / PU) roj tais system yuav tsum raug xam ua ntej. Nws tuaj yeem pom tau tias qhov ntau dhau ntawm lub cev yog kho, qhov muaj zog ntawm lub adhesion nyob rau hauv cov roj rau ntawm substrate, thiab qhov zoo dua lub composite fastness. Lub PVB number case yog tsim rau txhua daim ntawv thov drilling. Qhov no yog tam sim no feem ntau siv dav.
Lub hnub qub NC / PU roj kaw lus lig, tiam sis nws ua tau zoo dua hauv cov thwj cim, xim xim thiab ntxuav. Nws yog ib qho "kev tsim" roj rau cov flexo thiab gravure printing. Nws yog ib tus neeg zoo heev, nrog ob qho kev ua tiav ntawm kev kub ceev, ua kuab evaporation, ua kom tsis muaj zog thiab muab tshuaj txhuam. Tsis muaj yas lim. Tam sim no, nws txoj hauj lwm lag luam tseem raug qis dua tiam sis nws tau pom ib qho kev loj hlob zoo. PU number case plhom siv hauv Asmeskas muaj cov qauv zoo sib xws thiab cov qauv zoo li NC / PU number case. Nws ua ntej yuav tsum luam tawm nrog ib txheej kab dawb.
Txoj kev ua lag luam ntawm PVC number case systems yog maj mam txo. Vim hais tias tus cwj mem muab siv rau hauv nws muaj ib qho "grade", nws yuav siv tsis tau rau hauv lub hnab. Tsis tas li ntawd, qhov "vinegar" tivthaiv muaj nyob rau hauv cov kev ua haujlwm ntawm cov phom photopolymerization, yog li no tus number case no tsis yog nyob rau hauv cov ntawv luam tawm flexo. Yog li tam sim no nws tsuas yog siv nyob rau hauv gravure.
Kev ua yuam kev
Vim muaj kev piam sij ntawm lub paug thiab kev hloov ntawm cov khoom nyob hauv cov roj thiab cov muag dej, cov cai thiab cov cai tswjfwm tau txwv cov kev txwv rau qhov no, tshwj xeeb tshaj yog nyob rau hauv lub hnab ntim cov khoom noj thiab tshuaj yeeb yaj kiab.
Nyob hauv txhua txhua hnub, cov neeg siv yuav tsum tau ceev faj tshwj xeeb yog thaum yuav khoom nruab nrab ntawm cov khoom noj khoom haus vim cov khoom noj khoom haus yog qhov zoo thiab muaj feem xyuam rau lawv tus kheej. Yog cov kua txiv hmab txiv ntoo, kua txiv hmab txiv ntoo, kua txiv hmab txiv ntoo, kua txiv hmab txiv ntoo, cov dej cawv haus, cov khoom tu tawv nqaij, tshuaj tua kab mob, cov tshuaj tua kabmob, lwm yam zoo li. Yog tias siv tsis zoo thiab siv cov tshuaj siv, nws yuav ua tau rau hauv cov dej haus lossis cov khoom noj, uas yuav cuam tshuam rau kev noj qab haus huv ntawm cov neeg siv khoom.
Monomeric plasticizers, los ntawm cov roj txhuam los yog kev siv, yuav tau nkag mus (migrate) rau hauv cov khoom. Tsis tas li ntawd, qhov ua tiav ntawm cov tshuaj tua kab mob, kev sib tsoo los yog kev sib tsham kub thiab qhov lam tshuaj ntawm cov yeeb yaj kiab yuav raug txo yog tias cov khoom siv roj tsis zoo thiab siv rau kev siv qhov taub.
Xaus
Nws tseem ceeb heev los tsim ib zaj yeeb yaj kiab uas tsis tas ua tau raws li txoj cai lij choj tab sis kuj ua tau raws li tus neeg xav tau. Nws yog ib qho tseem ceeb kom muab cov txiaj ntsim ntawm cov khoom sib txawv mus rau hauv zaj yeeb yaj kiab. Txawm li cas los xij, cov txheej txheem ntawm cov kab mob sib khoob no yog ib qho nyuaj heev. Nws yog raws cov chaw tsim cov kev nkag siab ntawm cov tom qab, cov roj tshuab thiab cov dej haus drilling, thiab kev sib cuam tshuam ntawm cov ntaub ntawv no yuav tsum raug lees paub kom tsis txhob muaj teeb meem nrog kev ua cov ntawv tom qab tiav.
