การประยุกต์ใช้ใหม่สีอิมัลชันในกระบวนการชุบเหล็ก

Abstract

The aim of this chemical engineering project is to formulate an emulsion paint. The properties of hardness, specific gravity, viscosity and adhesion of the paint for iron coating dip industry were studied. The experimental results showed that the formulation of main parameters for the resin ratio of 46.01 percent, pigment ratio of 32.62 percent, solvent ratio of 18.83 percent, additive ratio of 2.11 percent and anti-rust ratio of 0.43 percent, were found to be the suitable formulation. From the property testing result, the pencil hardness scale is 4H, the specific gravity is 1.152, and the viscosity is 33.394 centistokes. The adhesion number is found to be 8 point, which gives better adhesion condition than that of the oil painting. The emulsion paint obtained from this research can be used in the iron coating dip industry because it gives better adhesion condition, and cheaper than oil painting. It also anti-rusting and odorless.
