Dispersant Testing in Water Treatment Agents

Dispersants are surfactants that have both the opposite properties of lipophilicity and hydrophilicity in their molecules. It can uniformly disperse solid and liquid particles of inorganic and organic pigments that are insoluble in liquids, and it can also prevent particles from settling and agglomeration, forming the amphiphilic reagent required for stable suspension. When the water treatment dispersant contains organic compounds with phenolic hydroxyl groups for membrane separation treatment of the water to be treated, the water treatment dispersant will cause almost no reduction in the amount of permeate water due to the adhesion of organic compounds to water. The surface of the separation membrane also has a carboxyl group, and has a structure that combines carboxyl carbon and nitrogen atoms.

Dispersant Formulation Characteristics

1. Enhance the leveling effect gloss.
2. Prevent floating color and flowering.
3. Improve coloring power.
4. Reduce viscosity.
5. Reduce flocculation component.
6. Increase storage stability.
7. Increase color spreading, color saturation, transparency and covering power.

Dispersant testing method

After determining the amount of dispersant required, the best value of dispersant must be determined to ensure that the amount of dispersant selected in the formulation can provide good rheology and sufficient stability.

Dispersant development

There are generally two ways to develop dispersants, one is to compound dispersants that have already been industrially produced, which can often give good results. The performance of the dispersant after compounding is greatly improved, which is conducive to reducing the cost of use, which is the fastest and most cost-effective way to develop new dispersants. Second, the chemical synthesis of new dispersants. On the basis of the relevant theoretical results, the successful research of new special and high-efficiency dispersants.

Composition analysis technology

BOC Sciences' testing technology tests the unknown components of dispersant samples through spectrograms and restores the basic composition of the samples.

Testing Instruments

FT-IR, GC-MS, LC-MS, NMR, etc.

Dispersant Action

The high performance liquid scale inhibitor/dispersant is mainly used to control scaling caused by calcium carbonate, sulfate and iron oxide precipitation in membrane separation systems. The application of this product can extend operating cycles and equipment life, thus reducing operating and investment costs.

Scale inhibitor and dispersant is a compound scale inhibitor and dispersant composed of organic polycarboxylic acid and sulfonate copolymer. It has good chelating and dispersing effect on calcium carbonate and calcium sulfate in water. It has strong strength of dirt resistance and is not easy to decompose.
