分光光度法用于烟草薄片浸渍涂料稳定性的研究

his experiment mainly studied the effect of guar gum and carboxymethyl cellulose as stabilizers on the stability of surface sizing coating for paper-process reconstituted tobacco. The experimental results showed that the viscosity, stability and absorbance of surface sizing coating for reconstituted tobacco increased, when guar gum was added into the coating. When the dosage of guar gum was 0.2 ~ 0.4%, the favorable stability was gained. However, the stability decreased due to the increase of viscosity of coating when the dosage exceeded 0.4%. The stability of surface sizing coating for reconstituted tobacco changed little with the increase of carboxymethyl cellulose, and this was due to the flocculation of small components in the coating for dipping reconstituted tobacco, which indicated that the carboxymethyl cellulose was less suitable for improving the application in coating for reconstituted tobacco than guar gum.
