品    名：多晶硅废水蒸发阻垢剂

型    号：SGR1105

主要成分: 有机膦酸盐、膦羧酸、聚羧酸类阻垢分散剂等。

理化指标：

性能用途：

   多晶硅生产和研磨过程中产生废水量较大，未回收利用的氯硅烷低沸物和氯化氢、提纯分离塔的不凝气体，还原炉开停炉置换尾气各系统检修时的置换尾气等工艺废气经尾气淋洗塔淋洗处理产生的酸性废水量与工艺废气的排放量、氯硅烷和氯化氢的浓度有直接关系，这部分废水中主要污染物为盐酸和氯硅烷水解产生的SIO2、以及废酸液，采用石灰中和、絮凝沉淀及压滤后，去除硅胶及悬浮物，通过蒸发脱盐，该废水高钙、高硬、高碱，高温蒸发极易结垢。

   SGR1105是专门针对多晶硅废水蒸发浓缩时的阻垢分散剂，在高钙、高碱度、高硫酸根和高硅的工况下仍有良好的阻垢效果。

使用方法：将SGR1105专用阻垢分散剂在加药罐中稀释后通过计量泵，按计量随废水一起加入蒸发器中，也可直接加入原液。一般用量为80～150ppm，根据水质情况确定具体用量。药剂使用之前应将加药箱和管线置换冲洗干净，避免影响使用效果。

包装贮运：用25kg、200 kg、1000kg塑料桶包装，存放于阴凉干燥处，贮存期十二个月，搬运时小心轻放，防止撞击。

SGR-1105

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.

    SGR-1105 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 SGR-1105 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 affecting the use effect.

Packaging and storage: with 25kg, 200 kg, 1000kg plastic barrels, stored in a cool and dry place, storage period of 12 months, carefully placed when handling to prevent impact
