The waterproof building materials water vapor transmission rate tester is a precision instrument used to measure the water vapor transmission rate of waterproof building materials. The following is an instrument brief introduction about the tester:
1. Overview
The water vapor transmission rate tester for waterproof building materials is mainly used to evaluate the water vapor barrier ability of waterproof building materials under specific conditions. The test results are of great significance for judging the performance of waterproof building materials and selecting waterproof materials suitable for different environmental conditions.
Second, the working principle
The water vapor transmission rate test of waterproof building materials generally refers to the industry standard GB/T 17146, and the working principle of the tester in line with the standard is mainly based on the moisture permeable cup weighing method (that is, the cup method). At a certain temperature, a specific humidity difference is formed on both sides of the sample, and the water vapor enters the dry side through the sample in the permeable cup, and the water vapor transmission rate and other parameters of the sample are obtained by measuring the change in the weight of the permeable cup with time.
3. Technical characteristics
- High-precision measurement: The tester uses high-resolution load cells to ensure high-precision measurement results.
- Multi-specimen parallel testing: Some models support accommodating multiple hygroscopic cups at the same time to achieve parallel testing of multiple specimens and improve testing efficiency.
- Intelligent operation: Equipped with humanized operation interface and intelligent data processing function, it is convenient for users to operate and manage data.
- Data management system: Support laboratory data management system to manage test results and test reports in a unified manner.
4. Scope of application
The tester is suitable for testing the water vapor transmission rate of waterproof building materials such as waterproof membranes, waterproof coatings, and waterproof insulation materials. At the same time, it is also suitable for measuring the water vapor transmission rate of other films and sheet materials.
5. Implementation standards
The implementation standards of the tester include GB/T 17146 (cup method), GB 1037, GB/T 16928, ASTM E96, ASTM D1653 and other relevant domestic and foreign standards.
Sixth, the test steps
- Specimen preparation: Select specimens that meet the test requirements and ensure that there are no defects or damage.
- Specimen mounting: Properly install the specimen in the tester's fixture or test chamber.
- Set test parameters: Set appropriate test parameters according to the test requirements.
- Start Test: Start the tester to test the water vapor transmission rate.
The above is a brief introduction to the instrument about the water vapor transmission rate tester for waterproof building materials. By using this tester, the water vapor barrier performance of waterproof building materials can be accurately evaluated, and reliable technical support can be provided for waterproof projects. 【Jinan Languang Electromechanical Technology Finishing】
