1引言由于钛在氧化性氯化物环境中具有优异的耐蚀性,其在化学加工业(CPI)中首先得到了应用,如作为氯-碱电解槽、湿氯气冷却器和泵、造纸厂的二氧化氯漂白设施,以及金属矿物酸浸用的压力反应器内部构件。目前钛在许多应用中都有超过25年的历史,包括化工厂、精炼厂、氯和氯化工制品生产厂、造纸厂、盐厂中使用的换热器、反应堆容器和蒸馏塔。 1 Introduction Due to its excellent corrosion resistance in oxidizing chlorides, titanium is first used in the chemical processing industry (CPI) as a chlor-alkali cell, a wet chlorine cooler and a pump, a paper mill’s Chlorine dioxide bleaching facilities, and pressure reactor interior components for metal mineral acid leaching. Titanium has been used for more than 25 years in many applications, including chemical plants, refineries, chlorine and chlorine chemical products manufacturing plants, paper mills, heat exchangers used in salt mills, reactor vessels and distillation columns.
