Adhesion hais txog ib qho phenomenon ntawm adhesion ntawm cov zaj duab xis yas hu tuaj. Muaj ob hom kev hnoos zoo li: ib qho yog qhov chaw uas muaj tus kabmob sib npaug sib. Qhov thib ob yog tias tus number case ntawm cov ntawv luam ua rau lwm qhov chaw ntu (feem ntau sab nraum qab ntawm zaj duab xis) los yog tus number case adheres rau lwm qhov chaw ntu. Tsab xov xwm no yuav coj koj los ntawm cov yam ntxwv ntawm kev siv tshuaj tua kab, kev xaiv substrate, thiab kev siv cuab yeej technology thiab kev sim kom nkag siab txog yam dab tsi uas ua rau cov nplaum ua tau yooj yim.
Adhesion hais txog ib qho phenomenon ntawm adhesion ntawm cov zaj duab xis yas hu tuaj. Muaj ob hom kev hnoos zoo li: Ib qho yog qhov uas luam tawm qhov sib txuam sib luag. Qhov thib ob yog tias tus number case ntawm cov ntawv luam ua rau lwm qhov chaw ntu (feem ntau sab nraum qab ntawm zaj duab xis) los yog tus number case adheres rau lwm qhov chaw ntu.
Qhov zoo tshaj plaws tshwm sim yog tshwm sim los ntawm kev siv ntawm cov yeeb yaj kiab rau ib leeg, lub qhov ncauj ntawm lub hnab ntim nyuab nyuab, thiab tus neeg siv tsis kam siv nws. Lub sab nraud tuaj yeem tiv thaiv tau los ntawm kev ntxiv ib tus neeg muag khoom, tus neeg sawv cev qhib, thiab cov zoo li lub pob cawv.
Qhov thib ob tshwm sim tau tshwm sim nyob rau hauv qhov tseeb tias cov khoom siv tsis tuaj yeem ua tsis ncaj rau, uas hinders zus tau cov kab hluav taws xob los yog ua rau lub zuag hluav taws xob luam tawm vim ntiv daim tawv tev thiab cov kab mob sib kis tau. Thaum mob hnyav, cov yeeb yaj kiab tsis tuaj yeem qhib thiab tsis tuaj yeem siv, uas ua rau cov khoom khoob. Yog li ntawd, yuav ua li cas los tswj thiab txhim kho txoj kev tiv thaiv ntawm tus cwj mem kua hauv cov txheej txheem gravure printing tshwj xeeb yog qhov tseem ceeb.
(1) Cov khoom siv thaiv khoom thaiv khoom
Cov khoom siv sib txuas yuav tsum muaj cov yam ntxwv nram qab no: 1 yob yob kev sib txeeb, kev ua haujlwm zoo, kom yoog tau los ntawm kev tsim cov khoom ntim high-speed; 2 tus npliag, qhov ntim zoo qhib.
(2) Kev xaiv ntawm cov khoom thaiv khoom thaiv
Hauv kev sau cov ntawv nyeem, "thaiv cov hlab ntim" muaj feem xyuam nrog rau ntau yam xws li substrate smoothness, number case adhesion, hnyav ua kom tsis muaj zog, chaw ua haujlwm, luam ntawv kom qhuav, thiab luam ntawv ceev. Kev xaiv ntawm lub substrate yuav tsum xav txog cov khoom saum toj no, thiab yuav tsum muaj cov yam ntxwv ntawm kev luam ntawv zoo txav, muaj zog number case adhesion, thiab kev daws teeb meem zoo. Cov khoom sib xws no muaj xws li BOPP zaj duab xis, BOPET zaj duab xis, cov ntawv txhuas roj hmab, PT film, thiab lwm yam, thiab tus cwj mem, hnyav thiab luam ntawv tsis sib haum nrog lub substrate.
(3) Cov kev qhia tshwj xeeb
Hauv cov ntawv nyeem gravure, cov cuab yeej thaiv cov teeb meem ntawm cov teeb meem tau zoo tuaj yeem los ntawm kev txhim kho thaiv kev tiv thaiv ntawm tus cwj mem. Yog li ntawd, ntawm txoj cai tiv thaiv kev tiv thaiv, nws yog qhov yuav tsum ua kom tiav cov cai ntawm kev ua kom tawv nqaij los ntawm kev tsim cov khoom thiab cov khoom raws li tej yam xws li hom pob tuav hauv tus cwj mem, cov tshuaj tsis haum, thiab cov khoom luam ntawv tsis .
(4) Kev sau ntawv tshwj xeeb
Siv cov khoom pov thaiv los tiv thaiv kev ua luam ua piv txwv, koj yuav tsum ua tib zoo saib xyuas cov teeb meem nram no thaum tsim cov txheej txheem luam ntawv: 1 Lub cwj mem ntawm cov nplais loj ntawm lub nplhaib yuav tsum tau xaiv los pab tiv thaiv kev ua tawm. Correspondingly, qhov hnyav tau muaj zoo solubility thiab tso cov cuab yeej rau tus qauv; 2 los xyuas kom meej tias cov ntawv luam tawm ntawm cov lauj kaub uas luam tawm tau yooj yim kom tswj tau qhov hnyav residue kom txo tau cov xim ntawm cov ntawv luam tawm; 3 Lub substrate xws li cellophane, nylon los yog ob qho tib si ua cov yeeb yaj kiab Tom qab cov cua ntsawj ntshab, sab nraub qaum tau muaj kev sib raug zoo nrog cov xoom txheej, thiab thaiv kev tsis zoo. Vim li no, txoj kev kho mob txoj kev kho mob, kev kho ib leeg, thiab kev qeeb qeeb ceev yuav tsum tau kho thaum lub sij hawm luam ntawv. Tom qab luam ntawv, nws yuav tsum tau txias txaus los ntawm kev ntim yob thiab tom qab ntawd rov qab.
(5) Txoj kev kuaj los ntawm kev sib tw
Kev kuaj tawm los ntawm kev sib tw ntawm cov pob zeb loj yog ua raws li cov cai ntawm GB / T13217.8-2009 "Intaglio yas number case inspection method - anti-blocking test".
1) Ntsiab Cai: Tus tau muab cov cwj mem xaj los luam tawm hauv ib lub sij hawm hauv ib lub sij hawm teev tseg, thiab nyob rau ntawm tej qhov kub thiab txias, tom qab lub sij hawm ib ntus, daim adhesion ntawm cov ntawv luam tau pom.
2) Cov kev kuaj mob: Qhov kev kuaj yuav tsum raug kuaj tawm ntawm (50 ± 1) ° C.
3) Tshuaj xyuas kauj ruam: 1 los ntawm luam tawm cov cwj mem ntawm luam tawm substrate, los yog siv lub pas hlau xuas luam tawm ntawm luam ntawv substrate; 2 tso cov piv txwv rau 2 feeb (yog tias cov luam yeeb yaj duab luam tawm nrog cov dej uas muaj dej, Yuav tsum muab ntim rau hauv qhov cub ci ntawm 59 ~ 61 ° C rau 5 min, coj tawm thiab txias. Nws muab tso rau hauv ib lub thawv ntim ntawm 49 ~ 51 ° C thiab nias nrog 2000 g. Cov cai muab tso rau 2h; 3 raug muab tshem tawm, thiab khi txoj hlua khi qhib, nyob ntawm seb nws qhov adhesion .
4) Cov txiaj ntsim tau los: Tshem cov khauj khawm nrog ib daim ntawv translucent milligram uas muaj qhov dav ntawm 20 hli. Cov xov tooj ntawm cov keeb kwm ntawm lub plhaub ntim quav thiab cov xov tooj ntawm cov neeg nyob hauv lub plev tawm ntawm cov kab uas raug tshem tawm yog qhov suav. Tshaj tawm hauv qab no
B (%) = B1 / (B1 + B2) × 100
B nyob rau hauv cov mis - cov degree ntawm number case adhesion
B1 - cov lej ntawm cov lej hauv tus number case txheej
B2 - cov naj npawb ntawm cov xauv npo uas tau muab tshem tawm
