Tsab ntawv no tsom mus rau cov nplaum laminating ob txheej uas tsis muaj kuab tshuaj, tham txog cov yam ntxwv ntawm cov khoom tsis muaj kuab tshuaj.
1. Lub ntsiab lus tseem ceeb ntawm Kev Txhim Kho Vaj Tse
Cov yam ntxwv ntawm kev sib npaug yog lub peev xwm ntawm cov txheej txheem kom sib npaug thiab du ntawm qhov chaw ntawm cov substrates.
2. Kev sib raug zoo thiab cov teebmeem ntawm kev nce qib ntawm ntau theem sib txawv
Hauv kev sib tham hauv qab no, cov ntsiab lus ntawm kev tsim khoom yuav zoo ib yam, suav nrog qhov hnyav ntawm txheej, kub, siab, thiab lwm yam. Vim tias txhua yam yuav ua rau muaj kev hloov pauv rau cov laminates kawg, peb yuav pom cov hloov pauv no raws li kho.
Vim tias cov nplaum uas tsis muaj kuab tshuaj tsis muaj kuab tshuaj ua lub hauv paus, qhov ua kom sib npaug yog qhov ua tau zoo ntawm cov nplaum. Hais txog qhov sib piv, nws yuav huv dua, tab sis cov nplaum uas tsis muaj kuab tshuaj tseem muaj nws tus yam ntxwv.
Ua ntej, cov khoom siv ntawm SF nplaum muaj kev sib raug zoo nrog viscosity ntawm cov nplaum nws tus kheej. Thaum viscosity muaj kev sib raug zoo nrog qhov kub thiab txias thiab sib txawv inversely, 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 nplaum muaj qhov sib txawv loj raws li cov qauv nplaum SF sib txawv thiab cov khoom siv lub cev. Txawm li cas los xij, nyob rau hauv qhov kub ua haujlwm kom zoo ntawm ib qho qauv nplaum SF, qhov sib txawv ntawm nws cov viscosity tsis pom tseeb heev. Yog li, cov khoom viscosity qis tej zaum yuav tsis yog qhov zoo dua thaum piv rau ib qho qauv nplaum SF siab viscosity nrog ib qho viscosity qis. Piv txwv li, WD8262A / B ntawm KANGDA COV NTAUB NTAWV TSHIAB, nyob rau hauv nws qhov kub ua haujlwm (nyob ib puag ncig 45 ℃), nws cov viscosity yog 1100 mpa.s. Tab sis thaum laminating PET.INK / ALU, nws tuaj yeem ua tiav qhov zoo nkauj tsis muaj dots thaum thawj lamination. Raws li kev xaus lus, nws tsis txhais tau tias viscosity qis tuaj yeem coj qhov zoo nkauj. Kev hloov pauv dynamic ntawm SF nplaum yog lub sijhawm ceev ceev, uas xav tau ntau yam ntsiab lus kom ncav cuag qhov zoo. Lub caij no, viscosity muaj qhov qis tshaj plaws hauv pem teb. Piv txwv li, nyob rau hauv 80-90 ℃ (Ob chav tivthaiv SF nplaum), viscosity muaj me ntsis hloov pauv nrog qhov kub nce.
Kev ua kom tiaj tus thawj zaug yog kev txuas ntxiv ntawm cov nplaum sib xyaw. Tom qab txheej txheem txheej, nws cov khoom sib xyaw txo qis ntxiv nrog rau kev teb sai ntawm A & B cov khoom thiab qhov kub poob qis. Feem ntau, kev ua kom tiaj tus thawj zaug ntawm SF nplaum yog suav tias yog kev ua kom tiaj tus tom qab laminating winding. Lub sijhawm no qhov viscosity ntawm cov nplaum yuav loj dua li cov nplaum sib xyaw ntawm cov menyuam ntsuas.
Kev sib npaug ntawm cov nplaum nyoos txhais tau tias cov khoom sib npaug ntawm cov nplaum hauv cov thoob ua ntej sib tov. Cov khoom sib npaug no tsis koom nrog cov txheej txheem ntawm kev laminating ntawm cov yeeb yaj kiab lossis cov ntawv ci.
Qhov thib ob theem leveling yog tias, tom qab laminating txheej txheem thiab mus rau hauv theem kho, SF nplaum mus rau theem ntawm kev sib txuas ceev ceev hauv qab qhov cuam tshuam ntawm qhov kub thiab txias, thiab kev ua haujlwm leveling txo qis kom ploj mus tag.
3. Xaus Lus
Cov khoom sib npaug ntawm cov nplaum SF nyoos ua ntej sib xyaw > cov khoom sib npaug thib ob > cov khoom sib npaug ntawm cov nplaum SF sib xyaw ntawm cov menyuam ntsuas > cov khoom sib npaug thawj zaug. Yog li ntawd, qhov sib txawv ntawm kev hloov pauv viscosity ntawm cov nplaum SF yog qhov txheej txheem nce siab, uas pom tseeb txawv ntawm cov nplaum SB.
Yog tias koj muaj lus nug txog SF laminating rau cov ntim khoom yooj ywm, peb txaus siab los pab koj.
