Polysilicon wastewater evaporation scale inhibitor SGR1105

Product name: polysilicon wastewater evaporation scale inhibitor

    Model number: SGR1105

Main components: organic phosphonates, phosphonate carboxylic acid, polycarboxylic acid scale resistance dispersant, etc.

physicochemical indexes:

Performance and purpose:

Large wastewater in the process of polysilicon production and grinding, Unrecycled chlorosilane low boiling material and hydrogen chloride, non-condensable gas of the purification tower, Reduction furnace opening and stopping furnace replacement exhaust gas after the exhaust gas shower tower shower treatment of acid wastewater and the process exhaust gas emissions, chlorosilane and hydrogen chloride concentration has a direct relationship, The main pollutants in this part of the wastewater are SIO 2 produced by the hydrolysis of hydrochloric acid and chlorosilane, and waste acid solution, After using lime neutralization, flocculation, precipitation and pressure filtration, Remove the silicone and the suspended matter, Desinerting by evaporation, The wastewater is high in calcium, high hard, high alkali, High temperature evaporation is easy to scale.

SGR1105 is a scale resistance dispersant specifically for the evaporation and concentration of polysilicon wastewater. It still has good scale resistance effect under the working conditions of high calcium, high alkalinity, high sulfate and high silicon.

Usage: dilute SGR1105 special scale resistance dispersant in the dosing tank through the metering pump, according to the measurement into the evaporator together with the wastewater, or directly into the stock solution. The general dosage is 80~150ppm, and the specific dosage is determined according to the water quality. Before the use, the medicine cabinet and pipeline should be replaced and rinsed to avoid affectin.
