3. Application
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 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 .
Packing: 25kg bags.
Storage: two years and must be upload and download lightly.
