Features: This book is compiled by the Shanghai Coatings and Dyes Industry Association. It introduces spray granulation drying technology in the post-processing of dyes and pigments and its application in dye and pigment production. The book also covers the application of high-speed colloid mills and high-pressure homogenizers in dispersion and post-processing of ultrafine powder. It discusses the application of rotary flash evaporation dryers in the chemical production of phthalocyanine and other organic pigments. Additionally, it explores the use of hot air permeable belt drying technology in the production of organic pigments and the application of membrane separation technology in the production of reactive dyes and colored wastewater treatment. The book also details the application of hot air circulating ovens, material loading machines, and conical screw mixers in dye and pigment post-processing. It covers coal-fired, oil-fired, and gas-fired hot air furnaces, as well as lignin sulfonates—a key auxiliary agent in post-processing—as used in dye post-processing. The book also provides practical experience, working principles, performance, and selection criteria for the aforementioned applications. This book is suitable for professionals in the dye and pigment industry, as well as students and faculty in fine chemical programs at universities and colleges.
