Tetrasodium iminodisuccinate



Tetrasodium iminodisuccinate (IDS) has a wide range of applications in various fields, including agriculture, water treatment, papermaking, and printing and dyeing industries. ‌

1. Application in the field of agriculture

IDS is mainly used as a chelating agent in agriculture, which can effectively separate heavy metal ions in soil and improve the yield and quality of agricultural products. Due to its high bioavailability and environmental efficiency, IDS is considered an effective means of improving the yield and quality of agricultural products. In addition, IDS can also be used as a micro fertilizer supplement to provide trace elements for plants and promote plant growth.

2. Application in the field of water treatment

In terms of water treatment, IDS has good biodegradability and is environmentally friendly. It can be used as a water treatment agent, scale inhibitor, and water softener, effectively reducing the formation of scale and improving water utilization efficiency. IDS is particularly adept at integrating transition metal ions such as calcium, magnesium, and zinc, and its ability to integrate heavy metal ions such as copper and iron is comparable or even better than traditional integration agents such as EDTA, which can significantly improve water quality. In addition, IDS can also be used to clean rust and sulfide scale in metal pipeline networks, suitable for hard surface cleaning tasks such as natural gas pipeline cleaning.

3. Application in papermaking and printing and dyeing industries

In the papermaking and printing and dyeing industries, IDS is used as a bleaching agent, which can provide higher whiteness and stability than traditional oxidants. When mixed with sodium silicate, it can reduce the formation of silicon scale and improve the quality of paper. This chelating agent not only protects pulp fibers, but also increases the dispersibility of bleaching solution, thereby improving bleaching efficiency and saving costs.

Sodium iminodisuccinate, as a sticking agent, can effectively improve the adhesion of wet paper on the surface of the Yangke dryer, solve problems such as tearing, paper jamming, and uneven wrinkling, and reduce the yellow edge phenomenon on the surface of the dryer. It is suitable for crescent paper machines and provides excellent control technology for producing soft household paper. ‌
