Embodiment Construction
[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0037] figure 1 This is the flow chart of the online automatic determination method of accelerator concentration in the embodiment of the present invention.
[0038] See figure 1 , the online automatic determination method of accelerator concentration of the embodiment of the present invention comprises the following steps:
[0039] S1: Preparatory work before the detection, check the liquid inventory in the reagent bottle 30 and the pure water bucket 32 in the online detector to ensure a sufficient amount;
[0040]S2: Start the online detector, set parameters on the touch screen 4, and use the sampling pump 22 to extract the sample solution and the water pump 23 to extract pure water to rinse the cuvette 36 and the pipeline, and drain the rinsed waste liquid through The valve 29 is discharged into the waste liquid bucket;
[0041] S3: extract a set...

The invention discloses an online automatic determination method of accelerator concentration, comprising the following steps: S1: preparation work before detection; S2: start an online detector, set parameters on a touch screen, and rinse the reaction cup and pipeline; S3 : Pass the sample solution into the reaction cup for the first titration; S4: Drain the solution in the reaction cup into the waste liquid bucket, and rinse the reaction cup and pipeline; S5: Draw the sample liquid into the reaction cup and carry out The second titration; S6: Calculating through two titration steps to obtain the concentration of the accelerator nitrite in the sample solution. The present invention has online automatic sampling analysis, automatic calibration and cleaning, and automatic unmanned management and control of phosphating liquid medicine; labor cost saving, safety and efficiency; high-precision visual detection unit ensures the stability and accuracy of end point determination; For accurate metering of water samples and reagents, each reagent is obtained by an independent peristaltic pump, which avoids cross-contamination between reagents.
Description
technical field [0001] The invention relates to a method for measuring the concentration of a reagent, in particular to an online automatic measuring method for the concentration of an accelerator. Background technique [0002] Pre-coating treatment refers to eliminating all kinds of oil stains and dust on the surface of the coated object before coating, and the cleaning process to make the coated surface clean is an indispensable process in the pre-coating process; how to clean the coated surface? A chemical treatment or mechanical processing treatment is selected according to the substrate and surface state of the object to be coated, and the requirements of the coating process. The pre-coating treatment includes three parts: degreasing, rust removal and phosphating. Phosphating is the central link. The so-called phosphating refers to the process in which a metal workpiece is treated with an aqueous solution containing phosphoric acid, phosphate and other chemicals, and a...
