Adhesive Index
Lub viscosity thiab cov ntsiab lus ntawm cov nplaum rau corrugated board yuav tsum tau kho raws li lub caij nyoog. Feem ntau, ntawm qhov kub thiab qis qis (lub caij ntuj no), viscosity ntawm cov nplaum rau ib leeg-corrugated cardboard yog 17-21s (txheej 4 khob, tib yam hauv qab no), thiab cov ntsiab lus khoom yog 17% -19%; viscosity ntawm cov nplaum rau peb-corrugated cardboard yog 40-60s, cov ntsiab lus khoom yog 18% mus rau 20%. Nyob rau hauv kub thiab high humidity (lub caij ntuj sov), viscosity ntawm cov nplaum rau ib corrugated cardboard yog 20-25s, thiab cov ntsiab lus ntawm cov khoom yog 19% -22%; viscosity ntawm cov nplaum rau peb-corrugated cardboard yog 55-90s, thiab cov ntsiab lus khoom yog 21% -25%. %. Tsis tas li ntawd, nws yuav tsum tau xyuas kom meej tias cov nplaum nplaum ntev (dhau me ntsis nplaum ntawm tus ntiv tes xoo, daim ntawv cog lus nrog tus ntiv tes ntsuas, maj mam rub ob tus ntiv tes sib nrug mus rau qhov deb ntawm ob tus ntiv tes thaum cov nplaum tawg) yog 15-20mm.
