3 Terms and definitions

The following terms and definitions apply to this document.

4 Principle

Add a nominal volume of sodium hydroxide solution into the glassware and use an ultrasonic oscillator to perform ultrasonic extraction to dissolve the tin deposited on the inner surface.

The solution was dissolved in sodium hydroxide solution, and hydrochloric acid solution was added to adjust the pH and make the volume constant. The solution was analyzed by inductively coupled plasma emission spectrometer and other instruments.

The amount of tin element in the liquid is tested to obtain the deposition amount of the hot end spraying liquid on the inner surface.
