Ua qhov tseem ceeb ntawm Cov Qhov Tshuaj Ntawv Ua Haujlwm Txog Qhov Ntsws

Txiav xim rau cov lus nug uas zoo tshaj plaws

Thaum cov neeg siv cov lus nug rau cov kev xaiv tso cua thiab tso cua hauv qhov chaw, cov lus sib pab yuav tshwm sim rau cov ntaub ntawv hauv qhov chaw: gloss los yog matte, soft touch los yog standard. Cov lus nug no yog qhov tseem ceeb, tab sis lawv tsis nrhiav qhov lus nug tseem ceeb uas yog: cov nqaij yuav tshwm sim li cas thaum siv rau lub neej ntawm cov khoom siv thiab cov ntaub ntawv? Nqaij tso cua thiab tso cua hauv qhov chaw tseem ceeb tsis yog qhov kev xaiv uas cov neeg siv marketing tau muab qhia. Nws yog qhov kev xaiv uas muaj kev txaus siab rau cov kev tshwm sim hauv kev siv nyob hauv lub neej ntawm cov khoom siv thiab cov ntaub ntawv thaum tso cua thiab tso cua hauv qhov chaw mus rau thaum cov neeg siv khoom tshem tawm cov khoom.

Cov rooj tseem ceeb ntawm cov adhesive layer

Kev lamination thermal yog li ua haujlwm los ntawm kev cog lus adhesive coating uas tau muab tso rau lawm thiab muab txuas nrog qhov cua sov thiab qhov ntau, txuas cov film rau hauv qhov ntaub ntawv hauv ib zaug. Qhov nyab xeeb ntawm kev txuas yog nyob ntawm peb qhov tseem ceeb: kev sib txuas ntawm adhesive, kev sib txuas ntawm qhov ntaub ntawv, thiab kev sib txuas ntawm kev ua haujlwm. Yog tias muaj kev sib txuas tsis zoo rau lub tsev no, ces kev txuas yuav muaj kev xav tias zoo rau thaum kawg, tab sis nws yuav tsis tuaj yeem ua haujlwm thaum muaj kev ntau.

Kev sib thag ntawm surface energy yog qhov teeb meem uas yuav tsis raug ntsiab tshaj plaws. Cov substrate uas muaj surface energy siab, piv txwv li UV-coated boards thiab cov aqueous coatings tseem ceeb, yuav tiv taus kev nkag mus ntawm adhesive, tsaug rau kev lamination temperature zoo. Ib qhov test rau surface energy uas siv contact angle measurement, raws li uas tau piav qhia rau hauv ISO 19403, yuav paub tau qhov tsis sib thag no kab laij ua ntej muab mus rau press. Qhov kev ua ntej ua kom paub tau no yog ib qho kev ua haujlwm tseem ceeb rau cov converter uas muaj kev paub ntau, tab sis yog qhov uas tau ua tsis tau rau cov haujlwm uas tseem ceeb dua.

Cov cuab yeej uas pab zoo dua li kev npaj rau cov khoom

Cov ntaub ntawv tshuab thiab tshuab yuav muaj kev nyab xeeb rau qhov lwm ntawv, tab sis qhov tseeb ntawm nws tsis yog rau kev siv hauv qhov sib tham ntawm lub cim.

Qhov tsis yog qhov tseem ceeb ntawm qhov khoom yog qhov tsis tau txais kev ntsiab ntau. Siv qhov khoom siv rau qhov khoom siv 115 g/m2 uas muaj qhov tsis yog qhov tseem ceeb yuav tsoo qhov tsis yog qhov tseem ceeb ntawm qhov khoom siv rau lub sijhawm ntev, uas yuav tsoo qhov khoom siv nyuaj tsis loj thiab tsis muaj kev tswj hwm qhov tsis yog qhov tseem ceeb ntawm qhov khoom siv thaum kawg.

Yam li cas qhov nyuaj ntawm qhov khoom thiab qhov yam ntxwv ntawm qhov khoom siv sib pab

Kuam txawv ntawm kev xaiv cov ntaub tshuab 12 micron, 20 micron lossis 25 micron tsis yog ib yam li kev txiav txim siab rau qhov kev npaj tau. Cov ntaub tshuab loj dua muaj kev npaj tau zoo dua, tab sis yuav tsum muaj kev npaj tau zoo rau qhov cua sov thaum lub sijhawm kaw cov ntaub tshuab kom cov adhesive (ntaub tshuab kaw) ua haujlwm zoo rau txhua qhov ntev ntawm cov ntaub tshuab. Lawv kuj ntxiv ntau ntau rau qhov loj ntawm cov khoom thaum tiag, uas muaj kev nyuaj rau cov kev siv uas muaj kev kawm rau qhov loj ntawm cov khoom los ntawm lub rooj tshuab lossis rau qhov kev kawm rau qhov kev tswj hwm ntawm carbon.

Rau cov kev siv hauv kev kho tshuab thiab kev kho cov khoom siv rau tsev xwb, 15 mus rau 20 micron yog qhov zoo heev. Cov ntaub tshuab 15 micron rau hauv cov ntaub tshuab artboard 400 g/m2 uas raug kho nrog cov ntaub tshuab ntau yam hauv qhov cua sov 85°C mus rau 95°C yuav muaj kev npaj tau ntawm 220 mus rau 260 g/cm yog tias cov adhesive (ntaub tshuab kaw) yog qhov zoo rau cov ntaub tshuab uas muaj cov ntaub tshuab kaw rau hauv cov khoom.

Tswv yim ntawm kev siv hauv cov chaw uas muaj kev txhawb nqa ntau

Kab tshuab tshuab tshuab uas muab cov khoom tshuab tshuab rau cov khoom tshuab tshuab hauv Southeast Asia tau pom qhov teeb meem uas yuav tshwm sim ib yam dua: tom qab muaj sijhawm 2 lub hlis nyob rau hauv cov khoom tshuab tshuab, cov khoom tshuab tshuab rau sab saum toj tau muaj qhov ntsuas ntsuas uas tuaj yeem pom ntawm qhov ntsuas ntsuas. Qhov teeb meem no tau los ntawm qhov kev sib sau ntawm cov khoom tshuab tshuab uas muaj UV-coated thiab qhov kev sib sau tsis zoo rau cov khoom tshuab tshuab uas tau siv, thiab qhov ntau ntau ntawm cov khoom tshuab tshuab hauv cov khoom tshuab tshuab. Yog li, muab cov khoom tshuab tshuab thermal lamination film los siv, uas muaj qhov adhesive ntau dua thiab muaj qhov kev sib sau zoo rau cov khoom tshuab tshuab uas muaj UV-coated, tau txhawj tshwm sim qhov teeb meem ntawm cov khoom tshuab tshuab tom ntej. Qhov tseem ceeb tshaj plaws yog tias qhov kev sib sau ntawm cov khoom tshuab tshuab yuav tsum sib sau rau cov sijhawm tshuab tshuab, tsis yog rau cov sijhawm tshuab tshuab tshwj xeeb.

Sauv cov Lus Qhia Tshuab Tshuab Ntawm Cov Lus Qhia Tshuab Tshuab

Cov ntaub ntawv txheeb xyuas ntawm cov film muaj qhov peeling strength, qhov haze, qhov gloss nyob rau hauv 60 degrees, thiab qhov thickness. Qhov uas lawv tsis nco qhia rau yog qhov kev hloov ntawm cov qhov no tom qab muaj UV exposure rau 500 teev, tom qab muaj kev hloov ntawm qhov ceev ntawm 5°C thiab 40°C, lossis tom qab muaj kev nyob rau hauv 50% relative humidity rau 72 teev. Yog koj tham rau cov thawj tswv uas muaj cov ntaub ntawv txheeb xyuas uas tau hloov los ntawm cov ntaub ntawv txheeb xyuas tshiab, ces koj yuav paub tau tias cov ntaub ntawv twg yog muaj cuab yeej nyob rau hauv qhov chaw uas muaj kev siv, thiab cov ntaub ntawv twg yog muaj cuab yeej nyob rau hauv cov ntaub ntawv xwb.

EKO qhia tias lawv muaj kev txheeb xyuas rau cov ntaub ntawv uas tau hloov rau hauv lawv cov ntaub ntawv muaj cuab yeej, uas qhia tias lawv muaj kev tsim cov khoom uas muaj kev siv nyob rau hauv qhov chaw uas muaj kev siv, tsis yog kev txheeb xyuas rau hauv cov chaw txheeb xyuas uas muaj kev kawb.
