Machine principle of anti metal droplet impact performance tester:

This device is used to check the protective effect of protective clothing under the thermal shock of molten metal droplets. Click to drive the lever at a constant speed to approach the acetylene/oxygen flame, and the rod will melt in contact with the flame; Molten metal droplets fall into a funnel and enter the sample; The sample is installed on the vertical surface of the heat flow sensor; The dehumidification temperature of the heat flow rate is already recorded when the first metal droplet falls off; The continuous impact of melted metal droplets causes the temperature of the heat flow sensor to rise; The amount of droplets needs to be increased to increase the temperature of the heat sensor at a rate of 40K in order to obtain significant test results.
