Kev xaiv ntawm kub yaj nplaum ncaj qha cuam tshuam rau ntug banding zoo. Nws yog ib qho tseem ceeb uas yuav tsum tsom rau cov ntsuas tseem ceeb suav nrogviscosity, qhib lub sij hawm, softening point, thiab bonding zog, thaum ua ib qho kev ntsuam xyuas ua ke nrog cov txheej txheem txheej txheem thiab cov yam ntxwv ntawm substrate.
Viscosity txiav txim siab lub fluidity thiab txheej uniformity ntawm kub yaj nplaum, nrog sib txawv viscosity yuav tsum tau nyob rau hauv txawv kub. Piv txwv li, siab -kub nplaum feem ntau muaj viscosity ntawm 45,000–120,000 mPa·s ntawm 200℃. Cov khoom nruab nrab mus rau siab viscosity raug pom zoo rau siab - ceev ntug banding tshuab.
Lub sijhawm qhib yog hais txog lub sijhawm ua haujlwm tau zoo los ntawm daim ntawv thov nplaum rau nias. Kub yaj adhesives nrog siab pib sib txuas lub zog feature lub sij hawm qhib luv dua thiab xav tau ib tug ceev ntug banding ceev. Nyob rau hauv qis- qhov kub thiab txias ib puag ncig, cov khoom lag luam nrog lub sijhawm qhib ntev dua yuav tsum raug xaiv kom tsis txhob kho ua ntej nias txaus.
Lub softening point txhais cov cua kub tsis kam ntawm kub yaj nplaum; qhov siab dua qhov softening point, qhov zoo dua qhov kub tsis kam. Rau siab- qhov kub thiab txias xws li cov txee chav ua noj, cov nplaum nplaum nrog qhov muag muag ntawmNtau tshaj lossis sib npaug li 120 degreenyiam.
Bonding lub zog yog ib qho tseem ceeb qhia txog kev ua tau zoo, uas tuaj yeem tshawb xyuas los ntawm kev ntsuam xyuas kua muag lossis kev ntsuam xyuas lub zog tev. Nyob rau tib lub sijhawm, siab -kub kub yaj nplaum feem ntau xa cov zog siab dua li nruab nrab thiab qis- hom kub.
Tsis tas li ntawd, lub wettability ntawm cov nplaum rau lub substrate yuav tsum tau txiav txim siab. Tshwj xeeb tshaj yog rau cov nyuaj-rau- cov ntaub ntawv sib cog lus xws li daim ntawv melamine thiab ntoo veneer, cov khoom uas muaj cov substrate zoo affinity yuav tsum tau.
