Daim ntawv no tsom mus rau ob qho khoom hnyav-dawb laminating adhesives, sib tham txog qib khoom ntawm cov khoom hnyav-dawb.
1. Lub ntsiab lus tseem ceeb ntawm Leveling Property
Leveling cuab yeej yog muaj peev xwm ntawm coatings mus rau theem tusyees thiab smoothly nyob rau saum npoo ntawm substrates.
2. Kev sib raug zoo thiab qhov cuam tshuam ntawm kev sib tw ntawm cov theem sib txawv
Hauv kev sib tham hauv qab no, cov ntsiab lus ntawm kev tsim khoom ua haujlwm rau tib yam, suav nrog txheej hnyav, kub, siab, thiab lwm yam. Vim tias tag nrho cov ntsiab lus yuav ua rau muaj kev hloov pauv mus rau qhov kawg laminates, peb yuav pom cov kev hloov pauv no raws li qhov ruaj khov.
Vim tias cov kua nplaum tsis muaj kuab lom tsis muaj cov kuab tshuaj los ua lub hauv paus, cov cuab yeej leveling yog qhov ua tau zoo ntawm cov nplaum nws tus kheej.Hais txog kev hais lus, nws yuav yog purer, tab sis hnyav-dawb nplaum tseem muaj nws tus yam ntxwv.
Ua ntej, theem khoom ntawm SF nplaum muaj kev sib raug zoo nrog viscosity ntawm nplaum nws tus kheej.Thaum viscosity muaj kev sib raug zoo nrog qhov kub thiab txias sib txawv, uas txhais tau tias viscosity ntawm SF nplaum yuav txo qis thaum kub nce.Tom qab ntawd nyob rau hauv chav tsev kub, viscosities ntawm raw SF adhesives muaj qhov sib txawv loj raws li cov qauv sib txawv SF nplaum thiab cov khoom siv lub cev.Txawm li cas los xij, nyob rau hauv kev ua haujlwm kub ntawm ib tus qauv SF nplaum, qhov sib txawv ntawm nws cov viscosity tsis pom tseeb.Yog li, cov khoom uas tsis muaj viscosity tej zaum yuav tsis zoo dua thaum muab piv rau ib lub siab viscosity SF nplaum qauv nrog viscosity tsawg.Piv txwv li, WD8262A/B ntawm KANGDA NEW MATERIALS, nyob rau hauv nws cov kev khiav hauj lwm kub (nyob ib ncig ntawm 45 ℃), nws viscosity yog 1100 mpa.s.Tab sis thaum laminating PET.INK / ALU, nws muaj peev xwm ua tau zoo zoo li tsis muaj dots thaum thawj lamination.Raws li kev txiav txim siab, nws tsis txhais hais tias tsis muaj viscosity tuaj yeem ua rau pom zoo.Kev hloov pauv ntawm SF adhesives yog lub sijhawm nrawm, uas xav tau ntau lub ntsiab lus kom ncav cuag cov txiaj ntsig zoo.Meanwhile, viscosity muaj qis tshaj hauv pem teb.Piv txwv li, nyob rau hauv 80-90 ℃ (Ob chav tivthaiv SF nplaum), viscosity muaj me ntsis hloov nrog nce kub.
Frist leveling yog lub cev txuas ntxiv ntawm cov nplaum sib xyaw.Tom qab txheej txheej txheej, nws cov cuab yeej leveling txo qis ntxiv nrog rau cov tshuaj tiv thaiv sai ntawm A & B Cheebtsam thiab poob ntawm qhov kub thiab txias.Feem ntau, thawj theem ntawm SF nplaum yog suav tias yog theem tom qab laminating winding.Lub sijhawm no lub viscosity ntawm cov nplaum yuav loj dua li cov nplaum sib xyaw ntawm cov metering rollers.
Leveling ntawm raw adhesive txhais tau hais tias cov cuab yeej leveling ntawm cov nplaum hauv nruas ua ntej sib xyaw.Cov cuab yeej qib no tsis koom nrog hauv txheej txheem ntawm laminating zaj duab xis lossis foils.
Qhov thib ob theem khoom yog tias, tom qab txheej txheem lamination thiab mus rau theem kho, SF nplaum mus rau hauv theem ntawm kev sib txuas ceev ceev hauv qab ntawm qhov kub thiab txias, thiab kev ua haujlwm qib qis kom ua tiav ploj.
3. Cov lus xaus
Leveling cov cuab yeej ntawm raw SF nplaum ua ntej sib xyaw> thib ob theem khoom> qib khoom ntawm cov khoom sib xyaw SF nplaum ntawm metering rollers> thawj theem khoom.Yog li ntawd, viscosity hloov pauv ntawm SF adhesives tiag tiag yog txheej txheem nce, uas yog pom tseeb txawv ntawm SB adhesives.
Yog tias koj muaj lus nug txog SF laminating rau kev ntim khoom yooj yim, peb txaus siab pab koj.
