Cov yam ntxwv thiab cov luam ntawv kev txawj ntawm cov dej-ua ntej rau corrugated ntawvChocolate Box
Dej-bank number case yog ib puag ncig cov khoom lag luam zoo ib puag ncig cov khoom uas tau txais dav dav nyob rau hauv xyoo tas los noPastry BoxCov. Dab tsi yog qhov sib txawv ntawm cov kav dej-basulation thiab cov luam ntawv general ink, thiab cov ntsiab lus uas xav tau kev xav tau siv? Ntawm no, meibang yuav piav qhia nws meej rau koj.
Dej-based number case tau siv nyob rau hauv kev luam ntawv ntawm corrugated ntawv rau lub sijhawm ntev txawv teb chaws thiab ntau tshaj 20 xyoo nyob hauv tsev. Corrugated Daim Ntawv Luam Ntawv tau tsim los ntawm Lead Printing (Txhuas Printing), Offset Printing (Offset Printing (Offset Printing Printing Saj zawg zog nyem cov kua dej muaj kuj tsim los ntawm Rosin-txiv neej acid hloov resin series (qis) rau acrylic resin series (qib siab). Lub tshuab luam ntawv kuj tseem pauv los ntawm roj hmab phaj rau cov tais tais. Cov tshuab luam ntawv kuj tau tsim los ntawm ib qho xim nkaus lossis ob-xim presses nrog cov chais loj rau peb-xim lossis xim xim flexo.
Cov muaj pes tsawg leeg thiab cov yam ntxwv ntawm cov kua dej-raws li tib yam li cov neeg luam tawm kev lag luam dav hlau. Dej-based inks feem ntau muaj cov yeeb yaj kiab, binders, ib tug neeg saib xyuas thiab lwm yam. Colorants yog cov xim ntawm cov kua dej-based number case, uas muab cov kua qaub ib qho xim tshwj xeeb. Txhawm rau ua kom pom kev kaj lug ntawm flexographic luam ntawv, cov xim feem ntau siv cov pigments nrog cov tshuaj ruaj khov thiab muaj zog muaj zog; Cov phau ntawv muaj muaj dej, cob, Amine compounds thiab lwm yam kuab tshuaj organic. Resin yog qhov tseem ceeb tshaj plaws hauv cov inks dej. Dej-soluble acrylic resin feem ntau yog siv. Cov khoom siv khi ncaj qha cuam tshuam cov nplaum muaj nuj nqi, ua kom nrawm nrawm, thiab cuam tshuam rau cov kab thiab number cask kis ntawm tus mem kua. Amine compounds tsuas yog tswj cov neeg Alkaline Py tus nqi ntawm cov kav dej-ua number case, kom cov khoom siv acrylic tuaj yeem muab cov ntawv luam tawm zoo dua. Dej los yog lwm cov kuab tshuaj organic yog tsuas yog rhuav tshem cov resins, kho cov viscosity thiab ziab nrawm ntawm tus cwj mem; Cov neeg sawv cev ua haujlwm feem ntau suav nrog: defoamer, blocker, stabilizer, diluent, thiab lwm yam.
Raws li cov kua dej-based yog tshuaj ntxuav tes yog ib qho yooj yim los tsim cov npuas hauv kev siv, yog li cov roj uas muaj cov roj ntsha, thiab txhim kho cov pa hluav taws xob, thiab txhim kho kev sib kis tus mob ntawm tus cwj mem. Cov neeg thaiv tau siv los ua kom qhuav qhov ziab nrawm, tiv thaiv tus mem kua los ntawm ziab ntawm anilox yob thiab txo cov paste. Lub stabilizer tuaj yeem hloov kho tus lej pH, thiab tseem siv tau ua kev ua rau kom txo tau cov kua mem. Cov kua zaub kom huv yog siv los txo cov xim dej-based tso kua mis, thiab tseem siv tau los ua kom muaj zog los txhim kho qhov ci ntawm dej number case. Tsis tas li ntawd, qee cov ciab yuav tsum tau ntxiv rau cov number case dej kom nce nws cov coj tsis kam.
Dej-based number case tuaj yeem sib xyaw nrog dej ua ntej ziab. Thaum tus apek yog qhuav, nws yuav tsis muaj soluble hauv dej thiab number case. Yog li ntawd, tus cwj mem dej-based yuav tsum tau do ua ntej siv los ua kom tus cwj mem nyob rau hauv. Thaum ntxiv mem kua, yog tias cov number case nyob rau hauv lub taub hau tank muaj impurities, nws yuav tsum tau lim ua ntej, thiab tom qab ntawd siv nrog cov mem kua tshiab. Thaum luam ntawv, tsis txhob cia tus number case qhuav ntawm anilox yob kom tsis txhob thaiv lub qhov taub hau. Thaiv cov kab ke kom muaj txiaj ntsig ntawm number case ua rau kev nruam tsis muaj peev xwm. Thaum lub sij hawm cov txheej txheem luam ntawv, qhov Flexplate yuav tsum tau muab pov tseg los ntawm tus number cas kom tsis txhob thaiv cov qauv ntawv ntawm daim ntawv luam ntawv tom qab lub number case yog qhuav. Ib qho ntxiv, nws pom tias thaum lub viscosity ntawm dej-based number cas me ntsis, nws tsis tsim nyog ntxiv dej casually kom zam rau kev ruaj khov ntawm tus mem kua. Koj tuaj yeem ntxiv ib qho nyiaj tsim nyog ntawm stabilizer kom kho nws.
