[0002] Usually, the water resistance of fiber tubes at home and abroad is tested by immersing the sample in a fixed volume of water at a certain temperature, or boiling the sample in a fixed container. However, this method needs to be improved for glass fiber tubes because the surface area of glass fiber tubes is relatively large, and alkaline ions are precipitated after the hydrolysis reaction between glass fiber and water, which will cause the water environment to become alkaline due to the hydrolysis reaction, and further alkaline corrosion will occur. The water resistance of glass fiber examines the hydrolysis of water and glass fiber, so there is an inaccurate problem in the test results. Utility Model Content
