Application of Hydrolyzed Polymaleic Anhydride

[Application] Hydrolyzed polymaleic anhydride is very effective as a scale and corrosion inhibitor for industrial cooling water systems

(1) Anti-scaling mechanism

Hydrolyzed polymaleic anhydride has both lattice distortion and threshold effect, and has the effect of dispersing calcium carbonate and calcium phosphate crystallites

(2) Anti-scaling performance

Hydrolyzed polymaleic anhydride is suitable for use in circulating cooling water with high alkalinity, high hardness and high pH value.

Table 5-5 The relationship between the dosage of the medicament and the scale inhibition rate

Table 5-6 Scale inhibition rate of different calcium ion concentration

Table 5-7 The influence of temperature on the scale inhibition rate

It can be seen from the above table: ①The higher the temperature, the lower the scale inhibition rate under the same dosage condition; ②The higher the temperature, the greater the amount of reagent required under the same scale inhibition rate condition
