一、前言“80”金属酸洗缓蚀剂是一种以甲醛与苯胺为主要原料的醛胺类缩聚产物。它能溶于稀盐酸,对含有碳酸盐水垢的钢,用稀盐酸清洗除垢有良好的缓蚀效能。在一定条件下,对纯铝、合金铝、铅铜、紫铜等也有较好的缓蚀效果。它还具有合成工艺简便、原料易得、成本低廉、水溶性好、储存期长、应用范围广等特点。由于使用此法除垢效果良好,不腐蚀低高压容器,能大量节约能源和国家资财及劳动力,故具有重大经济意义。
First, the preamble “80 ” metal pickling inhibitor is a formaldehyde and aniline as the main raw material of aldehyde amine polycondensation products. It can dissolve in dilute hydrochloric acid, containing carbonate scale steel, with dilute hydrochloric acid cleaning descaling has a good corrosion inhibition. Under certain conditions, the pure aluminum, aluminum alloy, lead copper, copper, etc. also have a better corrosion inhibition. It also has the advantages of simple synthesis process, easy availability of raw materials, low cost, good water solubility, long storage period and wide application range. As a result of the descaling effect of this method is good, non-corrosive low-pressure containers, can save a lot of energy and state capital and labor, it has great economic significance.
