Problems solved by technology
The moisture permeability resistance of the frame glue directly affects the sealing performance and reliability of the liquid crystal cell. When water vapor enters the panel through the frame glue, the metal lines in the panel will be corroded, which will lead to problems such as horizontal lines in the product, so evaluate in advance The moisture permeability resistance of the frame glue is very important
[0004] At present, the method of weighing the weight change is usually used to measure the moisture permeability of the frame rubber. However, the commonly used frame rubber has good moisture permeability resistance and less weight gain, so a small error in weighing the weight will seriously affect the final moisture permeability calculation. As a result, and the weight gain method has the disadvantage of long time-consuming measurement

Abstract
The invention provides a device for measuring the moisture permeability of frame glue and a method for measuring the moisture permeability of frame glue. The frame glue moisture permeability measurement device of the present invention includes a measurement system and an air supply system, the measurement system includes a sealed tank, a flow meter and a trace moisture detector, the sealed tank includes a cover and a tank body that are arranged oppositely, and the cover An air inlet is provided on the body, and an air outlet is provided on the tank body. When measuring, the frame rubber film is sandwiched between the cover body and the tank body, and the air supply system passes through the air inlet. Water-containing gas is input into the sealed tank, and the flowmeter and trace moisture detector measure the gas flow and moisture content of the gas passing through the frame rubber film in the gas outlet respectively, so that according to the measurement data of the flowmeter and trace moisture detector within a certain period of time, , can quickly and accurately calculate the moisture permeability results of the frame glue, the operation is simple, and the accuracy of the measurement results is high.
