Abstract
In China, paste is the main adhesive material used during the process of painting and calligraphy mounting, and is key to determining the quality of mounting and a deciding factor for the success or failure of the whole process. Paste production conditions determine its serviceability. In this study wheat starch was used as the adhesive material, a rapid viscosity analyzer (RVA) was used to analyze the adhesive gelatinization curves obtained for pastes made under various conditions of concentration, stirring speed, stirring time and temperature. The results show that as the concentration increases, both the attenuation and retrogradation values increase, indicating poor stability of the paste and strong adhesive power after cooling. As the stirring time and frequency increases, the final viscosity decreases. The highest heating temperature has an effect on the adhesive gelatinization curve; the higher the heating temperature, the higher the gelatinization temperature and the higher the final viscosity. Physical property test instrument was used to test the influence of different aging times on the viscosity of starch paste. It was found that the longer time the gelatinized starch was kept, the more its macromolecular chains degraded or recrystallized and, as a result, the performance of the peel strength decreased, and adhesiveness also declined. Based on this study, it was found that the best conditions for preparing the paste are: paste concentration, 3 g/25 mL; heating temperature, 95[degree]C; stirring time, 2 minutes; and stirring rate, 12 revolutions/min. This study confirms traditional paste preparation techniques and provides a scientific basis for it.
