 [Use]

Printing and dyeing industry: mainly used for dyeing vat dyes suspension, leuco acid staining , dispersion and soluble vat dyes dyeing . Also be used for silk / wool interwoven fabric dyeing, the yarn is no color. Mainly used for industrial dye dispersion and diffusion of color lakes manufacturing additives.
Building materials industry : as early strength cement water reducing agent , the amount of 0.5-1% by cement cement after the shock has good dispersion effect , increasing the strength of cement .Diffused N of concrete tensile strength, impermeability, frost and compressive modulus of elasticity are improved, no corrosion of steel effect.
Pesticide industry: It can be widely used in wettable pesticides, with good dispersion and solubilization , can significantly improve the efficacy, dosage according to product requirements.Example: buprofezin , the amount of 3-5 % ; thiophanate amount of 0.8-1.5 % , 0.8-1 % Kai Ling vegetables .
Electroplating industry: the color is added, crossing pigment dispersants N allows uniform dispersion can significantly improve the plating surface brightness, and the amount is usually 10% of the pigment.
Rubber industry: rubber ( latex ) of industrial production process , the dispersed substances such as sulfur accelerator, antioxidant zinc oxide fillers ( such as barium sulfate , calcium carbonate ), etc., added to the dry weight of a dispersing agent N2-4% , 10% dispersant solution prepared in advance , and along with the other components in a ball mill grinding , can improve the dispersion effect and shorten the milling time .
