Introduction:

In various industries, waterproofing is a very critical link, so waterproof testing is an essential task.So what are the commonly used indicators in waterproof testing?Let me introduce it to you below.

1. Key indicators of waterproof performance

1.Hydraulic pressure test

The hydraulic pressure test is a key indicator for testing the water resistance of waterproof materials. It usually involves immersing the tested material in a large amount of water, and after a specified period of time, observing whether surface delamination, penetration, etc. occur in the tested material.

2. Steam penetration test

The steam penetration test is suitable for testing waterproof materials with certain breathability. Steam is usually allowed to penetrate into the sample within a certain period of time to evaluate whether the material is breathable.

2. Other indicators

3. Smell

Materials with good water resistance must not only meet technical specifications, but also have good adaptability to people.For products, smell is also a very important indicator, and the chemical substances that should be contained must not exceed the scope of national standards.

4. Appearance state of imitation stone coating

The apparent state of imitation stone coatings involves the quality of the material surface, which is closely related to each other based on microscopic performance differences. It is used very effectively in the project and requires considerable attention.

3. Usage effects and suggestions

So far, there are a wide variety of materials on the waterproof material market, and it is also important to choose the correct waterproof material.Determine the water density or dew point curve according to the specific situation.Repeat the correct scale test sampling average.Under normal circumstances, waterproof walls or waterproof Wanhua panels must be particularly careful when facing PU anomalies, cracks, cracks, etc., to ensure that the current internal to surface conditions are notified.It is recommended to use professional waterproof materials to better ensure the waterproof effect.

Summarize:

Waterproof testing is the most critical link in waterproofing projects. The main test indicators are hydraulic pressure test and steam penetration test.In addition, it is also effective to use odor and the apparent state of imitation stone paint as auxiliary indicators.When choosing waterproof materials, you need to consider the actual application conditions and purchase professional waterproof materials to ensure the waterproof effect.
