Product introduction
 产品说明
一、 适用范围
1.焦化、加氢系统
二、产品简介
本缓蚀剂是针对焦化加氢装置研制生产的专用缓蚀剂。此缓蚀剂是有机胺类吸附膜型缓蚀剂,分子结构中具有极性基团和非极性基团,极性基团吸附在金属表面上,而非极性基团由金属表面向溶剂排列。一方面由于缓蚀剂改变了金属表面的电荷状态,增大了腐蚀反应的活化能,使腐蚀难以进行;另一方面非极性基团多数排列在金属表面,形成疏水膜,阻止了与腐蚀反应有关的大部分电荷或腐蚀介质移动,达到抑制腐蚀的目的。此缓蚀剂再经精确复配,对H2S-HCL-CO2-H2O及有机酸有较强的中和作用,通过实验室内动态和静态实验表明,此缓蚀剂的缓蚀率在98%以上;经在多家炼厂使用证明对焦化和加氢系统有优良的缓蚀性能。
