Analysis of Characteristics and Research on Processing Method of the High Viscosity DW-1 Colloid

Abstract All the variation of the viscosity characteristics of the high-viscosity DW-1 colloid at different temperatures are mainly analysed in the paper. Based on the experimental data, it concludes that the heat treatment method at 45-65°C can keep the colloid with good fluidity within 15 minutes. The inhibitory effect of organic solvents on solid particles in colloids is also studied. By adding an appropriate proportion of Butanone to the DW-1 colloid, a better colloid particle treatment effect is obtained and the colloid curing speed is increased by about 2 times within 24 hours. Finally, the treatment methods and effects of colloids before spraying are summarized.
