Properties:
PESA is a phosphorus free, nonnitrogen green and environmentally friendly water-soluble polymer. PESA hasgood scale inhibition and dispersion properties on calcium carbonate, calciumsulfate, barium sulfate, strontium sulfate, calcium fluoride, and silicon scalein water, and has a good synergistic effect with phosphonates. PESA has goodbiodegradability performance and a wide range of applications, especiallysuitable for cooling water systems under high alkali, high hardness, and highpH conditions, and can achieve high concentration factor operation. PESA hasgood solubility with chlorine and compatibility with other drugs.
PESA can be used as a nanocalcium carbonate dispersant and can also be applied in the processing ofindustries such as papermaking, paint, ink, coatings, and daily chemicalindustry. The addition of PESA improves the flowability of calcium carbonatesuspension, improves the surface properties of calcium carbonate, reduces thesurface energy of particles, increases the affinity with the dispersion medium,effectively inhibits the agglomeration between particles, thereby increasingits dispersion performance and making it evenly dispersed in the body.

Usage:
PESA is suitable for fieldssuch as oilfield water injection and boiler water treatment; Suitable for circulatingcooling water systems in industries such as steel, petrochemicals, power,pharmaceuticals, etc; Especially suitable for boiler water treatment,circulating cooling water treatment, seawater desalination, membrane separationand other fields in high alkalinity, high hardness, high pH, and highconcentration systems; Suitable for the detergent industry.
When PESA is used in the fieldof water treatment, the addition amount is generally 10-30mg/L. When PESA isused as a dispersant, it is recommended to use a dosage of 0.5-3.0%, which canbe determined based on experiments. Due to the anionic nature of this product,it is not suitable to be used with cationic chemical additives.
