Jul 09, 2017

              Company's current products are cationic dyes, SD-type cationic dyes, mixed dyes and alkaline dyes and dyes intermediates, leading products for cationic dyes, mainly used in acrylic and blended wool dyeing and printing. Products are mainly sold to the EU, North America, Japan, Korea, Taiwan, Southeast Asia and South Asia and other regions, the international market share of 70%, the domestic market share of 30%.Blend Cationic Dyes

             Companies based on the dye industry a good atmosphere of development, with the help of superior human resources and technical resources, to seize the opportunity to cooperate with major universities, the use of advanced chemical environmental protection concepts and rich practical experience, with the company's excellent cationic dye development capabilities, the integration of the creation of a complete, advanced, modern green cationic dye research and development system, the development of a group of international development trends, with independent intellectual property rights of the new cationic dyes. The transformation of scientific and technological achievements into productivity, the company to build environmental protection, High-tech production enterprises, in order to China's cationic dye field to the international advanced level to contribute.Blend Cationic Dyes

            The adsorption of cationic dye methylene blue and malachite green by activated sludge was studied, and the effect of dye molar ratio, ion concentration and sludge dosing on adsorption of mixed dyes was investigated, and the adsorption data were fitted by Langmuir and Freundlich equation. The results showed that the adsorption of the mixed dyes with the sludge was in accordance with the pseudo two reaction kinetics, and the amount of adsorption point was determined by the sludge. The adsorption isotherm and Freundlich equation of the mixed dye are well fitted; the dye molar ratio has a certain effect on the removal of mixed dyes, 2 kinds of dyes are mixed with different proportions, and the removal rate of the mixed dye is between 2 kinds of one-component dye. When the sodium sulfate is less than the/, The increase of ionic concentration can promote the removal of dye, which is higher than that of/, and the removal rate of mixed dye is more stable than that of $number/, which is not affected by the concentration of sodium sulfate.Blend Cationic Dyes
