Kev ceev faj thiab kev daws teeb meem rau Nano-Cov ntaub ntawv luam tawm Embossed

Saum toj no (Embossed paper label printing: Can nano printing technology work?)), Tus kws sau tshuaj ntsuam xyuas qee qhov zoo ntawm nanoprinting tshuab los ntawm kev pom ntawm cov qauv luam ntawv thiab cov txiaj ntsig luam ntawv sib piv, thiab ua ntej tshawb nrhiav qee qhov teeb meem uas yuav tshwm sim thaum luam ntawv embossed ntawv cov ntaub ntawv. Hauv tsab xov xwm no, kuv yuav saib hauv - qhov tob nrog txhua tus.

01

Cov nyhuv ntawm number case filming thiab curing℃ntawm number case adhesion

Nano number case yog ua ntej-coated thiab qhuav rau ntawm ib tug rhuab conveyor siv, ces kis mus rau embossed daim ntawv ntawm ib tug ntxhib nto. Thaum lub sij hawm tus txheej txheem no, seb tus number case tuaj yeem khi nrog cov ntaub ntawv saum npoo thiab nkag mus rau hauv txhua qhov zawj kom tsim adhesion yog qhov tseem ceeb rau kev kuaj tus number case firmness.

Lub pre-conjunctival thiab ziab ntawm nano inks yuav tsum yog nruab nrab thiab kho tau. Ink tsis tuaj yeem tsim ib zaj duab xis lossis solidify tom qab ziab; txwv tsis pub, txheej number case poob nws cov viscosity thiab tsis tuaj yeem sib txuas nrog cov khoom tom qab hloov. Yog li ntawd, qhov℃ntawm kev tsim zaj duab xis thiab dryness ntawm nano number case - uas yog, viscosity ntawm tus number case txheej tom qab zaj duab xis - yog ib qho tseem ceeb ntawm kev daws qhov teeb meem ntawm number case adhesion.

02

Kev hloov ntawm tus number case formulations

Kho tus number case formula raws li tus yam ntxwv ntawm embossed ntawv. Piv txwv li, nce resin cov ntsiab lus (xws li xaiv acrylic resin nrog muaj zog affinity rau daim ntawv), ua kom cov number case cohesion thiab adhesion, kho cov tis ntawm nano number case pigments, tso cai rau tus number case kom zoo dua embossed kev nyuaj siab thiab ua rau kom muaj kev sib cuag cheeb tsam. Tsis tas li ntawd, cov additives yog ntxiv los txhim kho cov xim adhesion. Sim ntxiv cov neeg txhawb nqa adhesion (xws li silane coupling agents), uas tsim ib qho "choj" ntawm tus number case thiab ntawv, ntxiv dag zog rau kev sib txuas ntawm molecular, los yog ntxiv hnav- cov tshuaj tiv thaiv (xws li nano silica particles) txhawm rau txhim kho cov xim txheej ntawm cov xim sib txhuam thiab txo cov number case shedding thaum thauj thiab siv.

Kev hloov pauv txheej txheem luam ntawv

1. Precise tswj ntawm tus number case hloov tsis tau

Rov sim dua kom pom qhov tsim nyog tus lej hloov siab, qhov kub thiab txias, thiab nrawm rau daim ntawv embossed. Lub siab yuav tsum sib npaug, kom ntseeg tau tias tus cwj mem conjunctival ua tiav rau ntawm daim ntawv textured yam tsis muaj compressing ntau dhau thiab ua rau daim ntawv los yog number case zaj duab xis. Kub thiab ceev yuav tsum tau ua tib zoo sib koom ua ke; tswj cov zaj duab xis kub ntawm txoj siv conveyor (rubber daim ntaub) thiab hloov kub thaum nyob rau hauv kev sib cuag nrog cov ntaub ntawv luam ntawv los xyuas kom meej stability thiab adhesion ntawm tus number case tom qab hloov.

2. Ua kom zoo rau kev ziab kom qhuav ntawm tus number case nto

Lub nanoprinter yog nruab nrog cov ncej- xovxwm txheej, yog li tom qab hloov tus number case, tag nrho cov txheej txheem ziab (xws li infrared ziab thiab cua kub ziab) tuaj yeem ntxiv, tso cai rau tus number case los kho ntxiv, tsim ib zaj duab xis, thiab qhuav rau saum npoo ntawm daim ntawv embossed, yog li txhim kho tag nrho cov tuab ntawm tus number case txheej.

04

Khoom siv pretreatment

Thaum lub sij hawm embossing txheej txheem, embossed ntawv cov ntaub ntawv yuav ua puas lub fiber qauv, ua rau cov ntawv fibers los yog cov ntaub ntawv khib nyiab nyob rau saum npoo los yog tob rau hauv lub embossed nto. Cov teeb meem no cuam tshuam rau tus number case adhesion los yog ua rau cov pob dawb ntawm tus number case. Yog li ntawd, ua ntej luam ntawv, cov khoom siv tu (xws li ionized cua tu lossis electrostatic plua plav tshem tawm) yog siv los tshem tawm cov plua plav, roj stains, thiab lwm yam impurities los ntawm qhov chaw lossis sab hauv ntawm daim ntawv embossed. Koj tseem tuaj yeem siv cov kev kho mob corona uas tsim nyog rau daim ntawv saum npoo kom nce qhov nro thiab kev ua haujlwm, ua kom yooj yim rau cov kua nplaum kom ntub thiab sib kis, thiab txhim kho nws qhov kev sib txuas ua ke.

Kev Ntsuam Xyuas Zoo thiab Kev Tiv Thaiv

1. Kev sim thiab simulation validation

Ua ntej kev tsim khoom, ib qho me me ntawm cov qauv luam tawm raug sim los ntawm kev simulating tsheb thauj mus los (kev vibration, kev sib txhuam), kev siv scenarios (manual touch, environmental temperature and humidity change), thiab number case adhesion yog sim. Daim kab xev tev tawm tuaj yeem siv tau (xa mus rau cov qauv hauv tebchaws xws li GB / T 7707-2008 "Intaglio Decorative Printed Materials"), soj ntsuam tus number case shedding, los yog siv cov khoom siv coj los ntsuas cov tshuaj tiv thaiv ntawm cov ntawv luam tawm.

2. Tsim kom muaj cov qauv zoo thiab cov txheej txheem

Tsim cov qauv zoo rau nano- luam ntawv ntawm embossed ntawv caw daim ntawv lo, qhia meej cov cim ceev ceev (xws li tus lej tuav tus lej tom qab daim kab xev tev ntau dua lossis sib npaug li 90%), ntxiv cov qauv tshuaj ntsuam xyuas rau tus number case adhesion thaum lub sij hawm tsim khoom, tam sim ntawd txheeb xyuas cov teeb meem, thiab kho cov txheej txheem.

Zuag qhia tag nrho, nws yog technically ua tau los luam embossed ntawv caw daim ntawv lo siv nanoprinting tshuab, tab sis tus number case lub zog tseem yuav tsum tau ib tug tseem ceeb kev sib tw. Los ntawm kev kho tus number case, optimizing cov txheej txheem, pretreating cov ntaub ntawv, thiab combining nruj kev soj ntsuam thiab xyuas, qhov kev pheej hmoo ntawm tus number case dropping yuav txo tau zoo, xyuas kom meej cov luam ntawv zoo. Yog li ntawd, nws raug pom zoo kom pib nrog me me -batch sim ntau lawm thiab validation, ces maj mam nthuav mus rau loj -scale ntau lawm.
