Problems solved by technology

Although the electrolytic anolyte does not contain chromium, it is highly corrosive to the base material of the plate, which not only affects the service life of the plate, but also has poor gloss of the plate after cleaning, which is not conducive to the stripping of manganese products, and also makes the electrolytic metal manganese The joint surface of the product and the plate loses gloss, which affects the quality of the product

Abstract

The invention relates to a non-chrome washing agent for electrolytic metal manganese metal stainless steel pole plates, which is characterized by being formed by preparing an organic sequestering agent, an inorganic corrosion inhibitor, a builder, a surface active agent, an antifoaming agent, an anti-sediment agent and other non-heavy-metal inorganic salt and organic compounds. The washing agent has the advantages of being friendly to environment, low in operating cost, good in using effect, small in damage on the pole plates, rapid in manganese electrolysis of the washed pole plates, easy to treat plate washing wastewater and the like. The washing agent can not only reduce heavy metal discharge of electrolytic manganese metal industries greatly, but also contributes to yield stabilization, and reduces cost.

Description

technical field [0001] The invention relates to a chromium-free cleaning agent for electrolytic metal manganese and stainless steel pole plates. Background technique [0002] With the increasing pressure of environmental pollution and resource shortage in our country, the source control of pollution sources and the promotion of clean production in enterprises have become important means to improve resource utilization efficiency and reduce pollutant production, and their role in emission reduction has become increasingly prominent. [0003] Manganese metal is an important metal element, which is widely used in industry and is in great demand. It is an important raw material in the metallurgical industry. my country is the main producer of electrolytic manganese metal in the world, and the electrolytic manganese industry is an industry with high energy consumption and heavy pollution. The realization of clean production in the electrolytic manganese industry is not only the ...
