Dispersant MN dye dispersant, concrete water reducer, pesticide insecticide dispersant, battery anode expansion agent.

1. In the dye industry, it can be used as a dispersant, dispersant for vat dyes, diluent for acid dyes, and pigment dispersant. It can be mixed with dispersants MF and NNO, offering excellent thermal stability, dispersibility, and coloring power.

2. As a water reducer for concrete, it performs better than calcium lignosulfonate and is suitable for projects such as culverts, dams, reservoirs, and highways.

3. It can be used in geology and oilfield drilling to consolidate well walls and as a water shutoff agent in oil wells.

4. In agriculture, it is used for wettable pesticide insecticides and as a multivalent chelating agent to prevent the formation of curd in high-hardness water at 600ppm.

5. In the chemical industry, it serves as an expansion agent for the negative electrode of lead-acid batteries, improving low-temperature performance and discharge rates. In electroplating electrolytes, it ensures uniform plating without dendritic patterns; in the fur industry, it acts as a tanning agent, and in boilers, it functions as a descaling agent.
