BGD 520 IS0 1518 Automatic Scratch Tester Paint Surface Scratch Device
Description: The role of paint has three aspects: protection, decoration, and disguise the defects of the product, and these three roles are mainly with the hardness of the paint has a great relationship, the film hardness is one of the important properties that indicate the mechanical strength of the film, is an important indicator of the quality of the paint product quality is good or bad, and to measure the hardness of the paint film is an important indicator of the determination of scratch resistance;
Painted products in the packaging, transportation and use of the process inevitably be subjected to hard scratches, scratch-resistant paint film will often leave scratches, and even be scratched, which affects the decorative effect and make the paint film lose the protective effect. Therefore, people need a test method and evaluation standard that can be recognized by both supply and demand sides to test the scratch-resistant performance of paint to determine the level of scratches and types of defects.
Before 2015, there was only one relevant national standard GB/T 9279-2007 "Color Paint and Varnish Scratch Test" used to determine the scratch resistance of paint film, which is not very conducive to evaluating the scratch resistance of different coatings in different use environments. Later on, this scratch standard was revised and divided into two types: one is constant load, i.e., during the scratch test, the load of the scratching needle on the test plate remains unchanged, and the test result is expressed by the maximum load of the scratching needle that has not scratched the coating; the other is variable load, i.e., during the scratch test, the load of the scratching needle on the test plate is gradually increased from 0, and the test result is calculated by measuring the distance between the final load point and the point of the scratching needle. The result of the test is expressed by measuring the distance between the final load point and the point where the scratch has just appeared to calculate the critical load of the test plate at the point where the scratch has just appeared.
As the main drafting unit of this scratch standard, BiaoGeDa has developed an instrument that conforms to this standard, and after a large number of validation tests by many scientific research units, it is unanimously recognized as having very high reproducibility and comparability.
Main performance characteristics:
*The working platform can be moved back and forth, which is convenient for users to quickly switch between different test areas on the same test plate.
*Extra-large working platform, suitable for different sizes of the test plate (maximum test plate size 200mm × 100mm)
*Scratch needle through the test plate is the use of sound and light alarm system, more intuitive.
*With calibration certificate
