Khoom zoo muaj feem xyuam rau txoj kev ciaj sia thiab kev txhim kho ntawm txhua lub tuam txhab. Qhov zoo ntawm cov khoom yog nyob ntawm tsib lub khoom loj loj hauv cov txheej txheem ntau lawm: Txiv neej, Lub Cav, Cov Khoom, Txoj Kev, Ib Puag Ncig. Ntawd yog, peb feem ntau hais tias txoj cai 4MIE. Vim yog qhov sib txawv loj hauv cov nplai thiab qib ntawm cov yas yas xim luam lag luam, qhia txog 4MIE cov cai thiab qhov kev siv tiag tiag tsis zoo li qub. Vim cov kev txwv ntawm nyiaj txiag, rau feem ntau me me thiab nruab nrab tsuas muaj xim xim luam ntawv, cov khoom uas txo cov ntaub ntawv luam tawm thiab txo cov kev raug xwm txheej ntawm lub qhov chaw muaj kev ua haujlwm zoo. Nyob rau hauv tus txheej txheem ntawm cov xim xim printing, cov ntaub ntawv raw li peb hom yeeb yaj kiab, number case thiab hnyav. Txoj cai tswj kev tiv thaiv txhua yam: raws li tus neeg yuav tsum tau muaj los yog tus yam ntxwv ntawm lub pob txheem, tom qab ua tiav los txiav txim qhov tsim nyog zaj duab xis thiab qauv; tom qab xaiv cov qauv ntaub ntawv, raws li cov yeeb yaj duab sib txawv los teeb tus cim uas tsim nyog, thiab txhawb qhov sib thooj hnyav; tsis txhob ntim cov khoom ntim ntau dhau.
Muaj ntau ntau yam ntawm cov yeeb yaj kiab hauv lub khw muag khoom hnub no, tab sis feem ntau yog siv cov duab luam tawm BOPP, NY, PET, PE. Raws li qhov kev luam ntawv muaj kev txhawj xeeb, qhov tseem ceeb tshaj plaws yog qhov tseeb ntawm qhov kev kho cov nyhuv ntawm qhov yeeb yaj kiab, thiab seb qhov NY zaj duab xis yog qhov ntxooj. Cov txheej txheem yuav tsum tau ua rau zaj yeeb yaj kiab nto ntawm zaj duab xis yuav tsum tau tsim muaj thaum lub sij hawm luam ntawv. Cov nyhuv corona yog lub sij hawm-rhiab, thiab yog tias nws nyob ntev ntev, qhov teeb meem ntawm lub corona yuav poob ntau dhau los kom tau raws li cov kev xav tau luam tawm; nws tseem ua tau kom tsis txhob muaj qhov teeb meem ntawm qhov teeb meem ntawm qhov ua txhaum kev luam tawm. PE zaj duab xis yog qhov tseem ceeb ntawm peb cov xim: muaj tej zaum yuav muaj ib zaj duab xis yob txav mus rau kev kho mob thaum lub tshuab cov kauj ruam; tob tob los sis tsis sib npaug hauv cov xim ua kom tsis muaj teeb meem; cua tshuab zaj duab xis yog ntxiv ntau tus naj npawb tus neeg saib xyuas los sis siab dua Tshaj plaws kev faib ua feem ntawm cov ris seem ua rau qhov tseem ceeb hauv cov nyhuv corona. Thaum cov nyhuv ntawm ob sab ntawm cov yeeb yaj kiab 12 ~ 15umPET tsis txawv, nws yooj yim ua rau sab nraum qab ntawm cov ntawv luam tawm yob ua kom tawv nqaij. Corona cov kev cai rau cov duab luam tawm: BOPP, PE ≥ 38 dyne, PET ≥ 50 dyne, NY ≥ 52 dyne. Tom qab NY film absorbs dej, nws yuav tsis muaj ib tug zoo cawv rau cov nyhuv corona. Nws yog judged seb cov NY film absorbs dej thiab pom seb tus zaj duab xis shrinks los tsis. Thaum ib zaj duab xis muab txiav rau hauv qhov cub rau ob peb xuab moos, tes zoo li nyuaj, yog tias muaj qhov sib txawv Yog tias qhov tshwm sim tsis yooj yim, NY film absorbs dej ntau dhau. Yuav tsum tau muab cov duab yeeb yaj kiab tso rau tus neeg muag khoom ntawm kev siv thiab cov yeeb yaj duab, thiab tam sim no cov yeeb yaj kiab yog ua kom zoo dua, lub teeb pom kev zoo hu ua PET, NY, BOPP lub npe, cov chaw muag khoom muaj ntau yam, tiam sis tsis tas txhua yam.
Thaum xaiv ib tus cwj mem zauv, nws muaj ob peb yam tseem ceeb los xav txog: li cas lub substrate mus luam tawm? Dab tsi yog siv tshuab kom luam ntawv? Koj xav tias yuav ua li cas zoo li cas? Dab tsi yog qhov chaw rau kev luam ntawv tom qab thiab xaus kev siv? Niaj hnub no, number case manufacturers yog fiercely competitive, thiab muaj ntau chav rau khoom xaiv. Nws kuj yuav dazzle peb cov xim luam ntawv. Tshawb xyuas cov ntsiab lus saum toj no ua ntej luam ntawv, thiab xaiv tus number case nrog qhov kev ua tau zoo tshaj tus nqi, thiab txo los sis tsis txhob tshwm sim ntawm kev luam ntawv tsis ua. . Tus neeg muag khoom ntawm tus cwj pwm yuav tsum tsis ntau dhau, tsis pub ntau tshaj peb, tus cwj pwm ntawm ntau hom npe tsis tau muab sib xyaw thiab siv, ua rau muaj pov tseg ntawm tus lej residual; tej zaum muaj qee cov xim luam lag luam tuav lub tswv yim ntawm cov khoom tsim muaj lub lag luam, tiam sis lub tuam txhab yuav tsum muaj kev ntseeg zoo, nws yog qhov yuav tsum tau them sai dua los sis tom qab, tsis tas siv qhov no.
Peb lub hom phom feem ntau muaj nyob rau hauv kev ua lag luam: polyamide hom deg ntim hauv tshuab luam ntawv, chlorinated polypropylene type composite inks, thiab polyurethane inks. Txawv lub substrates raug xaiv rau cov phais sib thooj. Kev luam BOPP xaiv cov chlorinated polypropylene hom number case. Yog hais tias nws tsis tas yuav tsum tau compounded, nws yuav pom zoo cov qauv luam tawm npoo npog polyamide. Yog hais tias siv ntau hom polyurethane number case los luam tawm BOPP, tsis yog tus nqi siab siab xwb, tab sis cov kab xev nplaum kuj tsis ua raws li cov kev cai. NY, PET zaj duab xis yuav tsum muab luam tawm nrog cov cwj mem polyurethane. Yog tias nws luam tawm nrog chlorinated polypropylene number case, nws yog nquag ua tsis zoo xws li cov tev ntawm lub cev tsis muaj zog thiab kub kub delamination. Lub adhesion ntawm polyamide number case rau PE zaj duab xis yog tshwj xeeb yog zoo, tab sis nws tsuas yog siv rau kev qhuav ntim. Thaum ua siab kub, cov thawv rau cov roj thiab cov fwj dej uas tsis haum, xws li cov kua mis thiab lub raj mis, yuav tsum siv cov cwj mem polyurethane.
Muaj ntau cov cim tseem ceeb ntawm cov cim uas peb cov xim luam ntawv yuav tsum kuaj: viscosity, fineness, hue, thiab adhesion fastness. Cov khoom siv rau kev xeem yuav tsum muaj xws li ib lub bar (zoo ib Hawj, ua haujlwm ceev), 3 # Chaen Huai (viscosity), phaj fineness (fineness). Rau qhov kuaj pom viscosity, nws yog qhov zoo tshaj rau dilute rau ib hom viscosity (xws li 18 sec / 25 ° C) nrog rau kev sib xyaw kom haum rau xam cov nqi hnyav ntxiv, thiaj li tshem tawm qhov "cuav viscosity" phenomenon uas qee cov kev mob (ink ink: Nws yog tuab heev, tab sis nws tsis ntxiv hnyav.) Kev kuaj ntawm adhesion tuaj yeem xaiv tau los ntawm lub teb chaws (GB / T 13217.7-91), tab sis rau qee qhov luam ntawv hauv npoo yuav tsis txaus, nws yog qhov zoo tshaj rau simulate qhov kev txwv ntawm cov khoom ntim thiab tom qab ua haujlwm rau kev sim.
Qhov zoo ntawm qhov hnyav zoo uas cuam tshuam ncaj qha rau cov kev luam ntawm cov ntawv luam tawm, tab sis rau cov SMEs, qhov hnyav zoo tshaj yog qhov nyuaj tshaj plaws. Cov cim tseem ceeb rau qhov txawv ntawm qhov zoo thiab phem cov kuab tshuaj yog purity thiab noo noo cov ntsiab lus. Ntsuas zoo heev ntawm cov tshuaj siv tau yog qhov zoo tshaj plaws los ntawm chromatography, tab sis cov khoom siv yuav tsum kim kim thiab kev xav tau. Yog hais tias lub teeb yog rau kev luam ntawv, tsis hais tus txheej txheem qhuav kev xyuam xim, ntawm no yog ob peb yam yooj yim thiab cov tswv yim. Saib ntawm qhov hnyav ntawm qhov hnyav, tsawg kawg nws yuav tsum paub meej thiab pob tshab. Yog tias muaj teeb meem loj thiab ntab, qhov hnyav yuav tsum tau siv nrog ceev faj. Tom qab lub thoob tag los, tom qab lub sijhawm ntev heev los ntawm cov tshuaj uas tau siv los, tus neeg teb xov tooj muaj lub tswv yim ntawm qhov tsis hnov ntxhiab ntawm qhov hnyav. Yog tias qhov tsis hnov tsw tsw yog tsis ntshiab, nws yog qhov tseeb tias qhov hnyav tsis muaj purity thiab impurities. ntau. Siv lub hauv paus ntsiab lus ntawm kev daws cov dej ntws tawm los ntawm kev siv cov dej ntub dej hauv qhov hnyav: siv ib lub iav 100ml iav ntsuas lub plhaub loj loj, coj me me cov tshuaj hnyav xws li ester los yog ketone los kuaj, thiab sib npaug ncuav rau hauv toluene. Thaum nkag mus rau hauv toluene, saib seb puas muaj turbidity (milky white). Yog hais tias nws yog, cov ntsiab lus dej hauv qhov hnyav yog ua dhau lawm. Kev paub tau pom tias thaum cov dej haus tshaj 0.5%, qhov tshwm sim yog pom tseeb. Kev ntsuas roj ntawm benzene solvents tuaj yeem nqa tau los ntawm kev siv qhov hnyav los ntawm lub iav ntev thiab tsom xyuas seb puas muaj kev thev taus.
Muaj ntau ntau yam cuam tshuam txog kev luam ntawv. Peb yuav ua li cas peb thiaj li tau taub zoo ntawm cov ntaub ntawv luam tawm? Txhua lub xim luam ntawv muaj nws txoj kev tswj hwm. Qhov zoo ntawm kev tswj cov khoom nyoos yog qhov tseem ceeb tshaj plaws thiab cov txheej txheem tseem ceeb ntawm txoj kev luam xim. Nws nyuab nyuab heev uas xav tias tsis tsim nyog los yog tsis tsim nyog raw khoom tuaj yeem lav qhov tsim cov khoom tsim tawm. Yog li ntawd, peb cov xim luam lag luam yuav tsum ua kom zoo thiab siv tau ntev Cov khoom siv raw khoom kaw lawm.
