Embodiment Construction

[0023] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0024] Such as figure 1 Shown, the present invention comprises motor frame 1, motor 2, scale colorimetric tube 3 with stopper, motor switch 4, timer, scale colorimetric tube fixture 6; Timer and timer switch 5 link to each other, motor 2 and motor frame 1 is connected, the scaled colorimetric tube 3 is clamped in the scaled colorimetric tube fixture 6, and the scaled colorimetric tube fixture 6 is connected with the motor 2; when the motor switch 4 is turned on, the motor 2 can rotate clockwise or counterclockwise;

[0025] The sedimentation degree of barium sulfate is detected according to the following steps:

[0026] (1) First weigh a certain amount of barium sulfate sample and put it into the graduated colorimetric tube 3 with the stopper removed;

[0027] (2) Add an appropriate amount of water t...

Abstract

Provided is a method for detecting the sedimentation degree of barium sulfate. A motor rack, a motor, a scale colorimetric tube, a motor switch and a timer are included; the scale colorimetric tube is clamped in a scale colorimetric tube clamp, and the scale colorimetric tube clamp is connected with the motor. The method for detecting the sedimentation degree of barium sulfate comprises the following steps that a certain quantity of barium sulfate sample is weighed and placed in the scale colorimetric tube with a plug pulled up; a proper amount of water is added into the scale colorimetric tube to which a certain quantity of barium sulfate sample is added; the plug is plugged on the scale colorimetric tube again; the scale colorimetric tube with the plug plugged again is fixed to the scale colorimetric tube clamp connected with the motor; the motor switch is switched on, and the motor stops after fast rotating for certain time in the clockwise or anti-clockwise direction; after the motor stops, the scale colorimetric tube gets into a static state, a timer switch is switched on, the timer starts timing, and an alarm bell rings out after time is counted to the set moment; the volume of sedimentation liquid in the scale colorimetric tube is observed and recorded, and the volume is the sedimentation degree.

Description

technical field [0001] The invention relates to a method for detecting the sedimentation degree of barium sulfate added to a storage battery negative plate. Background technique [0002] In the production of batteries, barium sulfate is added to the negative electrode plate during production, and the quality of the product added with barium sulfate directly affects the quality of the battery in the later stage. [0003] Application number 201511018032.5, application publication number CN 105527275 A, the application document titled "A Method for Determination of Barium Sulfate Content in Lead-acid Battery Paste" discloses a method for the determination of barium sulfate content in lead-acid battery paste: " It is characterized in that, comprising the following steps: [0004] (1) Weigh a lead paste sample of mass M into a clean beaker, add analytical pure 1+4 nitric acid solution, heat to boiling, keep boiling for 5-10min, filter and wash the filter residue until there is n...
