Dab tsi yog lub luag haujlwm tseem ceeb ntawm Acid thiab Alkaline Resistance Ntawm Cov Pigments hauv Kev Siv Dej raws li Inks?

Cov resins siv nyob rau hauv dej-raws li inks yog feem ntau carboxylic acid hom, uas yog neutralized nrog ammonia thiab ua dej-soluble resins. Yog li ntawd, cov dej-raws li binders yog me ntsis acidic. Yog hais tias cov xim uas siv rau cov kua dej yog acidic, nws yuav ua rau acidification ntawm cov dej-soluble resin, uas ua rau resin condensation thiab kev puas tsuaj rau lub ncua kev kawm ntawv ntawm tus number case. Tab sis cov xim uas muaj zog alkalinity yog saponification ntawm resin; Pigments nrog cov dej solubility siab kuj tuaj yeem ua rau kev ruaj ntseg ntawm cov ntawv khi, yog li kev xaiv cov xim rau cov dej hauv dej yuav tsum xav txog yam xws li lawv cov acidity, alkalinity, thiab dej solubility.
