The above method is also described in "test method for tin plating amount of tin-plated steel sheet" (GB/T1838-2008). However, when the constant dc power supply is set, the current does not reach the set value I directly from zero, and therefore, a certain error occurs in the calculation of the integral value, which reduces the detection accuracy. Therefore, the integral value J needs to be corrected to eliminate the influence of the above factors on the final detection result.

In order to solve the technical problem, the current compensation method of the tin plate tin plating quantity analyzer comprises the following steps:
firstly, carrying out electrolytic treatment on a tinned plate sample, starting a constant direct current power supply, setting an output current set value of the constant direct current power supply, and measuring the actual output current of the constant direct current power supply according to a sampling frequency of 10Hz, wherein the sampling time t is 5 seconds;
step two, repeating the measurement of the constant direct current power supply output current in the step one for 20 times to obtain a group of output current measured values, dividing the output current measured values by the output current set value and taking the average value of the 20 measurements to obtain the ratio Q of the output current measured values to the output current set value;
step three, fitting data to the value Q to obtain a ratio Q function formula,
when t is<When 5, Q (t) = 1-e(-1.5t)
When t ≧ 5, Q (t) =1
Wherein: t is the sampling time of the output current measured value;
step four, integrating the function of the comparison value Q on the time t and dividing the function by the time t to obtain a compensation parameter k,
when t is<At 5, k =2 (e)(-1.5t)-1)/3t + 1
When t is more than or equal to 5, k =1-2/3t
And step five, after the compensation parameter k is obtained, multiplying the compensation parameter k by the integral value of the output current I of the constant direct current power supply on the time t to realize the compensation of the integral value.
The current compensation method of the tinning amount analyzer of the tinning plate adopts the technical scheme, namely the method obtains a group of current measured values and takes an average value after 20 times of actual current measurement of a constant direct-current power supply when a tinning plate sample is subjected to electrolytic treatment, the measured time is 5s, the current sampling frequency in the measurement is 10Hz, the ratio Q is obtained by the current measured values/current set values, data fitting is carried out on the ratio Q to obtain a ratio Q function formula, the ratio Q function is integrated and divided by the time t over the time t to obtain a compensation parameter k, and the compensation parameter k is multiplied by the integral value of the output current I of the constant direct-current power supply over the time t to realize the compensation of the integral value. When the method is used for measuring the tin content of the tin plate by using an electrolytic method, the influence of the current setting of the constant direct current power supply is eliminated, and the integral value is corrected, so that the tin content detection precision of the tin plate is improved, and the product quality is ensured.
