3M Daim kab xev rau iav: Kev lag luam ceev ceev
Mar 26, 2026
Hauv kev tsim iav, 3M daim kab xev tsis yog qhov kev xav tom qab- lawv feem ntau yog qhov sib txawv ntawm cov kab sib dhos huv thiab kev npau suav phem.
Dab tsi sticks (thiab dab tsi tsis yog)
Tsis yog tag nrho 3M tapes coj tib yam ntawm iav. Txoj kev mus-rau cov tsev neeg yog VHB (daim ntawv cog lus siab heev) rau cov qauv kev sib koom ua ke-xav tias tsis muaj iav railings lossis cov rooj sib tham-thiab nyias ob- cov ntaub nplaum zoo li 9495LE lossis 9088 rau mount qhov uas koj tsis tuaj yeem ua si. Rau kev sib txuas ntawm ntug lossis siab - raug tshav kub (tempered iav kab ua haujlwm), acrylic -cov ntaub ntawv tseem ceeb yeej dhau roj hmab- raws li cov. Roj hmab muaj hnub nyoog sai dua nyob rau hauv UV, acrylic tuav.
Surface prep yog txhua yam
Yog hais tias lub khob muaj cov txheej txheem: qis-E, ceramic frit, los yog anti-glare- koj khi rau txheej, tsis yog iav. Qhov ntawd hloov cov kab xev xaiv. Feem ntau lub khw hla cov primer tshwj tsis yog tias txoj haujlwm specs nws, tab sis rau sab nraum zoov lossis siab -load daim ntawv thov, 3M Primer 94 lossis 4298 yog qhov txawv ntawm "ntev" thiab "tawm hauv kev thauj mus los."
Qhov tseem ceeb ntawm kev xaiv
Load hom: shear vs. peel. VHB tuav shear zoo li champ. Peel zog xav tau ib tug nyias, firmer nplaum.
Kub thaum lub sij hawm thov: qis dua 50℃F, feem ntau acrylic tapes yuav tsis ntub dej kom zoo. Koj yuav tau txais daim ntawv cog lus thawj zaug tab sis pom creep tom qab.
Stack-up kam rau ua: iav yog nruj. Yog hais tias lub mating nto muaj warp, ib daim ntaub nplaum (VHB) absorbs nws; ib tug ntshiab adhesive zaj duab xis tsis.
Nco nco
Tib neeg overspec thickness xav thicker=muaj zog. Ntawm iav, 0.045 "VHB muab rau koj conformability, 0.025" muab rau koj shear stability. Kev hu tsis raug ua rau slippage ntawm kev teeb tsa ntsug lossis ghosting hauv qab iav.
Hauv luv luv: phim cov nplaum chemistry rau saum npoo (acrylic rau sab nraum zoov / UV), ua kom huv nrog hnyav (IPA lossis heptane), thiab hwm lub qhov rais kub. iav tsis flex -koj xaiv daim kab xev yuav tsum.
