Title (EN) CORROSION INHIBITOR, WELL, PIPELINE, AND METHOD FOR FORMING ANTICORROSION FILM
(FR) INHIBITEUR DE CORROSION, PUITS, CANALISATION ET PROCÉDÉ DE FORMATION DE FILM ANTICORROSION
(JA) 腐食防止剤、坑井、パイプライン、及び防食皮膜形成方法
Abstract:
(EN) This corrosion inhibitor is able to sufficiently prevent corrosion in the inner surface of a well or a pipeline, and contains: an inhibitor (A) which has a hydrophobic group and a polar group capable of donating an electron to a metal; an aromatic solvent (B); and hydrophobic particles (C).
(FR) L'invention concerne un inhibiteur de corrosion pouvant empêcher suffisamment une corrosion de la surface intérieure d'un puits ou d'une canalisation, et contenant : un inhibiteur (A) possédant un groupe hydrophobe et un groupe polaire pouvant donner un électron à un métal ; un solvant aromatique (B) ; et des particules hydrophobes (C).
(JA) この腐食防止は、坑井やパイプラインの内表面の腐食を十分に防止できる腐食防止剤であり、金属に電子を提供可能な極性基、および疎水基を有するインヒビター(A)と、芳香族系溶剤(B)と、疎水性微粒子(C)とを含有する。
