Adhesion thiab Suitability ntawm EVA Kub- Melt Adhesives

Hauv kev tsim khoom tiag tiag, kev sib koom ua ke ntawm kub- cov nplaum nplaum sib txawv nyob ntawm cov khoom xws li qhov kub thiab txias, hom thiab qhov zoo ntawm cov ntaub ntawv substrate, qhov dav thiab qhov tob ntawm cov nqaj qaum milling, qhov siab ntawm daim ntawv nplaum, thiab kev khiav hauj lwm ceev ntawm lub tshuab binding zoo meej.

(1) Qhov kub ntawm qhov kub ntawm kub - melted nplaum
Lub softening point ntawm kub -melt nplaum yog feem ntau siab tshaj 80℃; uas yog, cov nplaum yuav tsum pib mos thiab ntws ntawm qhov kub thiab txias. Txawm li cas los xij, qhov no tsuas yog qhov pib melting point; kom ua tiav lub xeev tsim nyog rau kev khi cov ntawv, qhov kub yuav tsum tau nce mus rau ntawm 130℃thiab 180 degree. Ntawm qhov ntsuas kub no, cov nplaum nplaum viscosity, fluidity, thiab tackiness yog qhov zoo rau phau ntawv khi.

(2) Kev sib raug zoo ntawm hom ntawv thiab daim ntawv thov kub
Txij li cov ntawv siv rau phau ntawv ntau lawm sib txawv hauv kev ntxhib los mos, cov nplaum daim ntawv thov kub yuav tsum tau kho kom haum. Qhov no tsis yog tsuas yog vim qhov sib txawv ntawm cov ntawv fibers tab sis, qhov tseem ceeb tshaj, vim tias kev hloov pauv ntawm daim ntawv thiab kev ntxhib los mos cuam tshuam rau thermal conductivity, yog li hloov qhov txias ntawm cov nplaum. Piv txwv li, thaum sib piv cov ntawv coated (xws li daim duab kos duab) nrog cov ntawv tsis muaj coated (xws li ntawv ntawv), cov nplaum nplaum yuav txias dua sai dua qub. Qhov no yog vim tias daim ntawv coated muaj kwv yees li kaum npaug ntawm cov teeb meem tsis muaj sia nyob hauv cov ntawv tsis muaj coated (xws li letterpress, ntawv xov xwm, lossis offset paper); txij li cov teeb meem inorganic muaj cov thermal conductivity siab, nws ua kom cov txheej txheem txias ntawm kub - yaj nplaum.
