              咪唑啉水溶性緩蝕劑

              關于咪唑啉水溶緩蝕劑

              咪唑啉在原油開采和煉化過程中,是一種性能優異、應用廣泛的緩蝕劑。

              咪唑啉由長碳鏈脂肪酸與多乙烯多胺經過高溫真空反應成環,一般結構式為,然后經過季胺化反應生成咪唑啉衍生物,再經過增效劑復配得到成品。此緩蝕劑能在鋼鐵表面形成一層致密的保護膜,一方面改變金屬表面的電荷分布和界面性質,使金屬表面的能量狀態趨于穩定化,減低腐蝕反應;另一方面由于非極性基團緊密排列在金屬表面形成一層疏水膜,使腐蝕反應得到抑制;同時它在金屬表面可以改變氫離子的氧化還原電位,也可以絡合溶液中的某些氧化劑,減低電位達到緩蝕的目的。

               咪唑啉水溶性緩蝕劑無特殊的刺激性氣味,穩定性好,毒性低,屬于環境友好型緩蝕劑。

              此緩蝕劑在中石化、中石油各煉化企業得到大量應用。

              使用方法及使用量

              1.用脫鹽水1:5-30均勻稀釋后,用計量泵連續注入。

              2. 按系統處理量的30--50ppm注入;前期注入量為正常期的2-4倍,三天后每天依次按5ppm的速度遞減至正常使用量。

              3. 本劑冬天使用時可適當用蒸汽加熱。

               

              包裝與儲存

              1.    200L塑料桶,IBC噸桶

              2.    宜放置陰涼通風處。不可靠近明火、酸堿類和氧化劑類化工品。

              操作注意事項

              1.    操作人員應穿戴乳膠手套及防護眼鏡等防護品。

              2.    如遇本物觸及皮膚時可用大量水沖洗后再用肥皂洗凈即可;如遇本物品濺入眼睛請在現場立即用水充分清洗之后立即就醫檢查。

              3.    如遇火災,可用干粉、泡沫、CO2 等滅火器以及黃砂滅火。
