Khoom ntawm Ntoo Adhesives

Polarity
Ntoo yog cov khoom siv polar nrog ib nrab ntawm cov pawg polar uas tsis txaus ntseeg ntawm nws qhov chaw; adhesives yuav tsum kuj muaj pawg polar los pab kom muaj kev sib nrig sib attraction ntawm opposite polarities, yog li tsim ib tug muaj zog daim ntawv cog lus nrog ntoo nto.
Kev ntub dej
Qhov no yog hais txog lub peev xwm ntawm cov nplaum rau kev ua raws thiab sib kis thoob plaws qhov chaw xws li ntoo. Wettability yog cuam tshuam los ntawm qhov nro thiab cohesive quab yuam; qis nto nro thiab cohesive quab yuam ua rau ntau dua adhesion thiab kis tau, thaum cov nqi siab dua ua rau tsawg dua. Txawm li cas los xij, kev ntub dej ntau dhau tuaj yeem ua rau cov nplaum tau nqus los ntawm cov ntoo, ua rau "cov pob qij txha tshaib plab" (cov nplaum tsis txaus) thiab noj ntau dhau. Qhov tsim nyog concentration thiab viscosity theem yuav tsum raug xaiv raws li cov ntaub ntawv tshwj xeeb raug sib koom ua ke.
Tus nqi pH
Adhesives uas muaj zog acidic los yog muaj zog alkaline tuaj yeem ua rau cov khoom siv dag zog ntawm cov ntoo, nrog cov acidity muaj zog muaj qhov cuam tshuam tshwj xeeb.
Molecular Weight Distribution
Kho (los yog tsim) qhov yuav tsum tau muaj qhov hnyav molecular ntau yam thiab kev faib tawm kom haum rau cov ntawv thov tshwj xeeb ntawm cov nplaum tuaj yeem txhim kho kev sib raug zoo ntawm lub zog thiab nrawm kho.
