品    名：多晶硅廢水蒸發(fā)阻垢劑

型    號：SGR1105

主要成分: 有機(jī)膦酸鹽、膦羧酸、聚羧酸類阻垢分散劑等。

理化指標(biāo)：

性能用途：

   多晶硅生產(chǎn)和研磨過程中產(chǎn)生廢水量較大，未回收利用的氯硅烷低沸物和氯化氫、提純分離塔的不凝氣體，還原爐開停爐置換尾氣各系統(tǒng)檢修時的置換尾氣等工藝廢氣經(jīng)尾氣淋洗塔淋洗處理產(chǎn)生的酸性廢水量與工藝廢氣的排放量、氯硅烷和氯化氫的濃度有直接關(guān)系，這部分廢水中主要污染物為鹽酸和氯硅烷水解產(chǎn)生的SIO2、以及廢酸液，采用石灰中和、絮凝沉淀及壓濾后，去除硅膠及懸浮物，通過蒸發(fā)脫鹽，該廢水高鈣、高硬、高堿，高溫蒸發(fā)極易結(jié)垢。

   SGR1105是專門針對多晶硅廢水蒸發(fā)濃縮時的阻垢分散劑，在高鈣、高堿度、高硫酸根和高硅的工況下仍有良好的阻垢效果。

使用方法：將SGR1105專用阻垢分散劑在加藥罐中稀釋后通過計量泵，按計量隨廢水一起加入蒸發(fā)器中，也可直接加入原液。一般用量為80～150ppm，根據(jù)水質(zhì)情況確定具體用量。藥劑使用之前應(yīng)將加藥箱和管線置換沖洗干凈，避免影響使用效果。

包裝貯運(yùn)：用25kg、200 kg、1000kg塑料桶包裝，存放于陰涼干燥處，貯存期十二個月，搬運(yùn)時小心輕放，防止撞擊。

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
