色浆应用时常见问题及分析

One is the reaction temperature. In the production process, the reaction temperature generally needs to reach about 170 °C, and after the production is completed, when carboxylic acid is added in the blending process, it needs to be cooled to below 60 °C, the temperature span is large, the energy consumption is very large, and it consumes time and greatly. Reduced production efficiency. Second: defoaming.

Colorants are further divided into water-based colorants, oil-based colorants and water-oil general colorants. Among them, water-based colorants are particularly widely used due to their environmental protection, but the high surface tension of water leads to the formation of bubbles, so the defoamer is required to have a very strong defoaming performance. The final production process needs to be improved. In the production process of color paste, it needs to go through processes such as dispersion, grinding and filtration. However, the traditional color paste production process is mostly discontinuous operation, the production cycle is long, and it is difficult to control product quality, so it is difficult to adapt to the color paste market. Rapidly growing demand for high-performance products.
