              Product introduction
               產品說明
              一、 適用范圍
              1.焦化、加氫系統
              二、產品簡介
              本緩蝕劑是針對焦化加氫裝置研制生產的專用緩蝕劑。此緩蝕劑是有機胺類吸附膜型緩蝕劑,分子結構中具有極性基團和非極性基團,極性基團吸附在金屬表面上,而非極性基團由金屬表面向溶劑排列。一方面由于緩蝕劑改變了金屬表面的電荷狀態,增大了腐蝕反應的活化能,使腐蝕難以進行;另一方面非極性基團多數排列在金屬表面,形成疏水膜,阻止了與腐蝕反應有關的大部分電荷或腐蝕介質移動,達到抑制腐蝕的目的。此緩蝕劑再經精確復配,對H2S-HCL-CO2-H2O及有機酸有較強的中和作用,通過實驗室內動態和靜態實驗表明,此緩蝕劑的緩蝕率在98%以上;經在多家煉廠使用證明對焦化和加氫系統有優良的緩蝕性能。
              三、質量技術指標
