PBTC: It mainly prevents scale formation by forming complexes with metal ions.
PAAS (Polycarboxylic Acid Scale Inhibiting and Dispersing Agent): It can disperse the microcrystals or sediment of calcium carbonate, calcium sulphate and other salts in the water without precipitation, so as to achieve the purpose of scale inhibition.
Dispersing performance:
PBTCA: It has good dispersing performance and can hinder the aggregation and deposition of tiny particles and solid particles.
PAAS: Excellent dispersing performance, especially suitable for high pH, high alkalinity and high hardness water quality.
