Atomic ash is a cement-based building material made of raw materials such as cement, lime, and quartz sand, and has good strength and durability. Atomic ash is mainly used for indoor and outdoor wall decoration and waterproof coatings. Its surface has a certain smoothness and texture, and its color is usually gray or light gray. Atomic ash can also achieve a variety of color effects by adding different color pigments, which is suitable for decoration needs in different styles and occasions.
Detection performance
Atomic ash is a kind of building material, the following performance parameters need to be tested, these parameters are very important for the production and use of atomic ash. The following is a table of performance parameters:
| performance parameter | Test Methods |
|---|---|
| construction performance | Observe the coatability, uniformity, ease of coating, etc. of the putty |
| drying time | Observe the drying time of putty |
| strength | Measuring the tensile and compressive strength of putty samples |
| Adhesion | Measuring the adhesion strength between putty coatings and substrates |
| Durability | Measure the weather resistance, water resistance and chemical resistance of putty samples under certain conditions |
| Environmental performance | Detect the content of environmental pollutants such as harmful substances and volatile organic compounds in the atomic ash |
Detection method
The following is a detailed description of the detection methods for various performance parameters of atomic ash:
Construction performance: observe the coating performance, uniformity and ease of coating of the putty during construction, and test the construction performance by evaluating the appearance and quality of the coating.
Drying time: Observe the drying time of the putty coating, and you can judge whether the coating is completely dry by touching, scratching, etc.
Strength: To measure the tensile strength and compressive strength of the putty sample, the tensile test method and the compression test method can be used to test the tensile or compressive strength of the sample under certain conditions.
Adhesion: To measure the adhesion strength between the putty coating and the base layer, the peeling test method can be used to test, the coating is peeled off under specific conditions, and the force required to peel off the coating is measured to evaluate the adhesion.
Durability: To measure the weather resistance, water resistance and chemical resistance of putty samples under certain conditions, various experimental methods can be used for testing, such as damp heat test, salt spray test, acid-base immersion test, etc.
Environmental protection performance: To detect the content of harmful substances, volatile organic compounds and other environmental pollutants in the putty, various chemical analysis methods can be used for testing, such as gas chromatography, liquid chromatography, etc.
Precautions
When testing, you also need to pay attention to the following issues:
Sample preparation: Sample preparation needs to be carried out in accordance with relevant standards or methods to ensure that the sample preparation process and conditions meet the requirements.
Experimental conditions: When performing various performance tests, it is necessary to control the experimental conditions, such as temperature, humidity, pressure, etc., to ensure the repeatability and accuracy of the experiment.
Test accuracy: For some performance parameters, such as compressive strength, tensile strength, etc., the test accuracy will be affected by many factors, such as sample preparation, experimental conditions, test equipment, etc., it is necessary to control these factors to improve the test accuracy.
Data analysis: After completing various tests, it is necessary to conduct statistics and analysis on the test data to determine the performance characteristics of the atomic ash and evaluate its quality level.
To sum up, the performance testing of atomic ash requires different testing methods and standards, and for some complex tests, professional laboratories or technicians are required. It is necessary to pay attention to the above problems when conducting the test to ensure the accuracy and reliability of the test results. At the same time, when using atomic ash, you should also pay attention to operating it in accordance with the instructions to ensure its better decorative effect and safety performance.
