Abstract

The invention discloses a volatilization rate measuring device which comprises a fan, an air outlet pipe of the fan is sequentially connected with a flow regulating valve, a flow monitor, a heater, an airflow dredger and a volatilizer through a pipeline, the volatilizer is connected to the fan in a backflow mode through a pipeline, and an explosion venting device and an air inlet regulating valve are further sequentially arranged on the pipeline between the volatilizer and the fan. The air inlet adjusting valve is further connected with an air inlet source. And the fan, the flow regulating valve, the flow monitor and the heater are all electrically connected with the controller. The invention further discloses a determination method of the volatilization rate determination device. The problem that in the prior art, the volatilization rate of coating liquid with complex components in a drying oven is difficult to quantitatively determine is solved. And guarantee is provided for accurate design of the length of the coating product drying box and correct partition of the drying stage.

Description

technical field [0001] The invention belongs to the technical field of high-end equipment testing, in particular to a volatilization rate measuring device, and the invention also relates to a measuring method of the volatilization rate measuring device. Background technique [0002] The next process after the coating liquid is coated on the surface of the substrate is generally hot air drying, that is, the coating liquid coated on the surface of the substrate is heated by hot air, and then the volatile components in the coating liquid are evaporated to achieve a cured coating. layer purpose. However, due to the continuous running of the substrate, its running speed is inversely proportional to the residence time of the substrate in the oven (ie, the drying time of the substrate). The time the substrate stays in the oven directly affects the drying effect and equipment energy consumption. At present, the method used by coating equipment manufacturers to calculate the drying...
