摘要
在化学沉铜工序中,为达到良好的除钻污效果,业界一般采用不断补充高锰酸钾来维持药水含量,但此作业方式不但消耗物料而且随着生产的不断进行也带来锰酸钾(六价锰)副产物的增多,这将导致逐步失去除钻污效果从而造成除钻污不净,本文从高锰酸钾法除钻污和再生器原理,相关参数、再生器设计及维护等方面进行介绍,并从中找出一种维持高锰酸钾七价锰含量的方法,从而解决生产过程中因高锰酸钾含量不足、稳定性差的问题,保证沉铜品质。
In the chemical copper precipitation process, to achieve good desmear ettect, the maustry generally uses constantly supplement potassium permanganate to maintain water content, but this operation not only leads to consumption of materials, and with the production of the ongoing, it also brings potassium permanganate （ six valence manganese ）deputy product increase, which will lead to a gradual loss of desmear effect thereby cause desmear net. The potassium permanganate desmear and regenerator principle, parameter design and maintenance, regenerator are introduced, and this article finds out a maintenance of potassium permanganate heptavalent manganese content methods, so as to solve the production process due to potassium permanganate content bad stability problem, and to ensure the quality of the copper deposition.
