冶金工业部建筑研究院同某冶炼厂协作,去年下半年进行了用煤沥青塑料和软质聚氯:乙稀塑料做铜、锌高温电解槽衬里的工业试点。这次试点是在两年前在常温铜电解槽中采用塑料衬里成功的基础上进行的,试点的电解槽用于高温电解,温度达56～63℃。试点工程经过半年来的生产考验,初步观察效果良好。过去,铜、锌等电解槽多采用铅村。铅衬里消耗很多铅,工程成本较高,还有在生产中容易漏电、“结铜”、使用寿命短、需经常检修等弊病。采用塑
The Ministry of Metallurgical Industry Construction Research Institute cooperated with a smelter. In the second half of last year, it carried out industrial trials using copper and zinc high-temperature electrolytic cell linings with coal-tar plastic and soft polychlorine:ethylene plastic. This experiment was carried out two years ago on the basis of the successful use of plastic linings in room temperature copper electrolyzers. The experimental electrolyzers were used for high temperature electrolysis at temperatures ranging from 56 to 63 °C. The pilot project has passed the test of production for half a year and preliminary observations have performed well. In the past, lead-free villages were used for electrolytic cells such as copper and zinc. The lead lining consumes a lot of lead, which has higher engineering costs, and also has the disadvantages of easy electric leakage during production, “copper”, short service life, and frequent maintenance.
