The application provides a glass corrosion resistance dynamic erosion device and an evaluation method, and belongs to the technical field of glass performance evaluation. A circulating spray system formed by an erosion liquid circulating pump and a spray nozzle sprays the erosion liquid in the form of mist droplets to the sample surface continuously and uniformly. This not only washes away the corrosion products on the surface, so that the fresh erosion liquid continuously contacts the sample and accelerates the reaction, but also simulates the actual dynamic working conditions such as rain and moisture splashing. Through the combination of the dynamic erosion device and the intermittent ion content detection, the loss rate of each component in the erosion process is monitored in real time to evaluate the erosion rate of the glass, which helps to analyze the erosion mechanism and guide product improvement. Meanwhile, the dynamic circulating spray device can wash away the corrosion products formed on the surface of the glass in time, simulates the glass use environment, and improves the accuracy of the evaluation effect.
