Real stone paint is a kind of high-grade decorative material made of natural stone powder, synthetic resin, pigment and other materials. It has the texture and texture of natural stone, but it is lighter, softer and more durable than natural stone. Real stone paint has a variety of colors and patterns to choose from, and can be applied to various decorative surfaces such as interior and exterior walls, roofs, railings, etc. of buildings. Real stone paint has the advantages of fire prevention, waterproof, anti-fouling, weather resistance, etc., and also has the advantages of easy construction and low cost, so it is very popular in the architectural decoration market.
Real stone paint needs to detect the following properties:
| performance | Test items |
|---|---|
| Bond strength | The degree of bonding between the real stone paint coating and the substrate |
| wear resistance | Abrasion resistance of real stone paint coating |
| weather resistance | Anti-aging performance of real stone paint coating under different climatic conditions |
| hardness | Hardness of real stone paint coating |
| Stain resistance | The anti-pollution ability of real stone paint coating |
| Color stability | Color stability of real stone paint coating |
| Crack resistance | Crack resistance of real stone paint coating |
| Acid and alkali resistance | Acid and Alkali Resistance of Real Stone Paint Coating |
| other | Such as coating fire resistance, water resistance, etc. |
The results of these test items can help evaluate the quality and suitability of real stone paint, and how it will perform in actual application. The test methods and equipment vary according to the specific real stone paint types and test items.
The following are common detection methods for real stone paint:
Adhesive strength: test the bonding degree between the real stone paint coating and the substrate by cross-cut method, peeling method, tensile method and other methods.
Abrasion resistance: Use abrasion test, scratch test and other methods to test the wear resistance of real stone paint coating.
Weather resistance: test the anti-aging performance of the real stone paint coating under different climatic conditions through artificial accelerated aging test or natural climate exposure.
Hardness: Use pencil Hardness Tester, Rockwell Hardness Tester and other equipment to test the hardness of real stone paint coating.
Anti-pollution: Use methods such as artificial pollution test and stain treatment test to test the anti-pollution ability of the real stone paint coating.
Color stability: Use light wavelength meter, color difference meter and other equipment to test the color stability of real stone paint coating.
Crack resistance: The crack resistance of real stone paint coatings is tested by methods such as flexure test and freeze-thaw test.
Acid and alkali resistance: Use acidity meter, alkalinity meter and other equipment to test the acid and alkali resistance of real stone paint coating.
Others: According to the specific types of real stone paint and testing items, select appropriate testing methods and equipment for testing, such as testing the fire resistance and water resistance of the coating.
The performance test of real stone paint needs to be carried out in accordance with relevant standards and methods to ensure the accuracy and comparability of test results. At the same time, the scope and accuracy of different detection methods are also different. Therefore, appropriate methods and equipment should be selected before testing, and adequate sample preparation and test plan design should be carried out.
