Abstract

The invention discloses an alkaline chemical nickel automatic analysis and adding system. The system comprises an alkaline chemical nickel groove and a sulfuric acid container, wherein the alkaline chemical nickel groove communicates with a sampling titration pump, the sampling titration pump communicates with a reaction vessel through first metering photoelectricity, and the bottom of the reaction vessel is provided with a stirring motor which is used for stirring the reaction vessel; the reaction vessel communicates with a nickel gauge circulating pump, and the nickel gauge circulating pumpcommunicates with a nickel probe; the sulfuric acid container communicates with a sulfuric acid titration pump, and the sulfuric acid titration pump communicates with the reaction vessel through second metering photoelectricity; and the nickel probe communicates with the reaction vessel and a control box. The alkaline chemical nickel automatic analysis and adding system can replace manual automatic analysis, investment of manpower cost is reduced, data errors caused by manual analysis mistakes are decreased, nickel ion concentration analysis within a short interval period can be achieved, through the concentration analysis within the short interval period, the adding amount of supplement additives can be adjusted more precisely, the fluctuation range of the concentration of technologically-controlled chemical liquid is stabilized, and the wasting amount of the supplement additives is decreased.

Description

technical field [0001] The invention relates to a chemical nickel addition system, in particular to an automatic analysis and addition system of basic chemical nickel. Background technique [0002] The method of plating a layer of nickel on metal or some non-metal by electrolysis or chemical method is called nickel plating. Nickel plating is divided into electroplating nickel plating and chemical nickel plating. Nickel electroplating is in an electrolyte composed of nickel salt (called main salt), conductive salt, pH buffer, and wetting agent. The anode uses metallic nickel, the cathode is the plated part, and direct current is applied to the cathode (plated part). Deposit a uniform and dense nickel coating. Bright nickel is obtained from the bath with brightener, and dark nickel is obtained from the electrolyte without brightener. Electroless plating is also called electroless plating, and can also be called autocatalytic plating. The specific process refers to: under c...

Problems solved by technology

At present, the nickel ion concentration of the nickel plating solution can only be obtained through manual sampling laboratory analysis;

[0005] 2. The manual sampling experimental analysis method is labor-intensive, and it takes a long time from the beginning of sampling to the result

Such an interval analysis method makes it impossible to monitor the ion concentration of the nickel plating solution in real time, so that the process conditions cannot be well controlled;

[0006] 3. Due to the use of manual sampling laboratory analysis to obtain the concentration of the main components of the potion, this process is time-consuming and laborious, so currently it is generally only analyzed 1-2 times every 8 hours

And use this analysis value to adjust the amount of additives added to the nickel solution. Such control is difficult to ensure the concentration fluctuation of the nickel solution within the process control range, and it is also easy to add a large amount and waste the additive solution
