The testing of internal surface water resistance of glass

Glass, as a common building material, the water resistance of its internal surface has an important impact on its service life and performance. Therefore, testing the water resistance of the internal surface of glass is crucial. This article will introduce the methods and techniques of testing the internal surface water resistance of glass.

The influence of moisture on the internal surface of glass not only leads to a decline in surface quality, but also may cause changes in optical properties and chemical corrosion. Therefore, testing the water resistance of the internal surface of glass is an important means to evaluate its performance and quality.

Drip testing is one of the simplest and most commonly used methods for testing the water resistance of glass inner surfaces. By dropping a certain amount of water on the glass surface, the spread and retention state of the water droplet can be observed, allowing a preliminary assessment of the hydrophilicity and water resistance of the glass. In addition, there are other methods such as contact angle testing, water pressure resistance testing, and chemical corrosion resistance testing that can be used to evaluate the water resistance of glass.

In droplet testing, we need to control parameters such as droplet size, drop height, and drop velocity to ensure the accuracy and reliability of test results. Contact angle testing measures the contact angle of a water droplet on the glass surface to assess its wettability. Water pressure resistance testing applies pressure to the glass under certain water pressure to observe whether leakage or cracking occurs. Chemical corrosion resistance testing exposes the glass to a certain chemical environment to observe whether corrosion or discoloration occurs.

Finally, we summarize the importance and commonly used methods for testing the internal surface water resistance of glass. Through these testing methods, we can comprehensively evaluate the water resistance and quality of glass, providing an important basis for its performance in practical applications.
