PBTCA (2-四 Tetic acid) is a commonly used dirt-resistant agent and has good shock resistance. The following is the main dirt resistance of PBTCA:
Calcium stain suppression: PBTCA can effectively inhibit the production and deposition of calcium dirt (such as calcium carbonate, calcium phosphate, etc.). It forms a stable complex with calcium ions to prevent the crystallization and precipitation of calcium salts, thereby preventing calcium dirt from stacking on pipelines, equipment and surfaces.
Iron scale suppression: PBTCA also has certain iron scale suppression capabilities. It can form a matching object with iron ions to prevent the formation and deposition of iron scale. This is very effective for preventing iron scale problems that occur in boilers and cooling water systems.
Corrosion inhibitory: In addition to the stain resistance, PBTCA also has certain corrosion inhibitory performance. It can form a layer of protective corrosion membrane with the metal surface to reduce the corrosion rate of metal.
Temperature adaptability: PBTCA has a good stain resistance in high temperature environments, suitable for high temperature systems, such as boilers and heating circulation systems.
Environmental friendly: PBTCA is a relatively environmentally friendly dirt -resistant agent that does not contain organic phosphate and nitride, and does not cause pollution to the water body.
It should be noted that PBTCA’s scale resistance performance is affected by factors such as concentration, water quality conditions, and operating temperature. In specific applications, the appropriate dose and operating conditions should be selected according to the actual situation to achieve the best dirt resistance. At the same time, we should also comply with relevant security operating procedures to correctly store and handle PBTCA.
