Xaiv Kub Melt Adhesive Rau Ntug Banding Machine

Tom qab lub ntug banding tiav lawm, rhuav lub ntug banding daim kab xev kom pom kev ntsuas lub zog tensile thiab soj ntsuam tus nqi ntawm cov ntoo chips adhering rau daim kab xev, los yog ua ib tug tensile tev test. Nyob rau hauv tib yam kev mob (lub ntsiab lus ntawm ntug banding tshuab, ntug banding sawb, txoj kev khiav hauj lwm, thiab ib puag ncig zoo tib yam), xaiv cov khoom uas muaj zog tensile zog.

Adhesive Strength thiab Affinity: Cov khoom sib txawv ntawm cov nplaum kub yaj muaj qhov sib txawv ntawm qhov pib tack zog thiab affinity. Adhesives nrog siab pib tack lub zog pab txhim kho adhesion thiab ua rau kom lub adaptability rau ntau yam ntawm ntug banding tapes, tab sis lub sij hawm qhib yog luv luv. Kev sib raug zoo zoo txhais tau tias muaj teeb meem tsawg dua nrog qee qhov nyuaj - rau - cov ntaub ntawv kaw.

Viscosity: Viscosity cuam tshuam rau thawj zaug tack zog thiab flowability ntawm kub yaj adhesives, nrog rau daim ntawv thov ntawm cov nplaum. Feem ntau, siab -kub nplaum ntawm 200℃muaj viscosity tus nqi ntawm 45,000 thiab 120,000 mPa·s. Txhawm rau kom nrawm dua ntug banding tshuab, yuav tsum xaiv qhov nruab nrab mus rau siab viscosity nplaum. Nruab nrab-kub nplaum nplaum ntawm 180℃muaj viscosity ntau ntawm 20,000-40,000 mPa·s; Cov nplaum nplaum kub ntawm 150℃muaj viscosity ntau ntawm 15,000-25,000 mPa·s. Viscosity qhov tseem ceeb tsis sawv cev rau lub zog viscosity.

Flowability: Flowability cuam tshuam rau qhov sib xws ntawm daim ntawv thov nplaum thiab nws qhov nkag mus thiab ntub dej ntawm lub substrate. Flowability ua rau tsis sib xws thiab tsis sib xws ntawm daim ntawv thov; nws kuj tiv thaiv cov nplaum los ntawm kev nkag mus rau hauv lub substrate thiab ua kom ruaj khov, ntsia hlau-zoo li zaj duab xis. Yog li ntawd, thaum xaiv cov nplaum nplaum kub, ua ntej cov khoom lag luam nrog cov dej ntws zoo ntawm tib qhov kub thiab viscosity tus nqi.
