With the increasing use of plastic molded products, it has become an important issue to improve the scratch resistance (scratch characteristics) from the viewpoint of the appearance (creative) of the surface of the molded product. Moreover, scratch resistance is also important from the viewpoint that the scars formed on the surface of the molded product may reduce the strength of the product.
Scratch test is carried out with a stylus pressing pattern to move horizontally (see "Principle of Scratch Tester").
The scratch characteristics were previously evaluated by the "constant vertical load test", but the American Society for Testing and Materials (ASTM) and the International Organization for Standardization (ISO) standardized the "vertical loading test" (ASTM D7027-05 / ISO 19252). This tester can be reviewed ISO and ASTM international standard "vertical loading test".
Application areas:
The tester uses steel needles to scratch the film, plastic, car interior and exterior decoration materials, coating materials, etc., to assess the material "scratch resistance (scratch characteristics)".
The main advantages of the "vertical loading test" are:
① can be quantitative evaluation of scratches
② affect the scratches of the load correlation can be evaluated with only one test
③ only a small number of tests to evaluate the scoring characteristics
④ suitable for the analysis of scratch structure.
Scratch tester features:
1, teaching function
Before using this function, the load area can be set with high accuracy.
2, the use of touch screen operation is simple
All functions can be used and set by installing the front touch screen.
3, the surface can also test the scratches
The vertical load of the Yaru drive unit uses the suspension mechanism, so that even if the surface has a convex pattern can also be tested, and does not affect the load linear increase characteristics.
4, can be memory test conditions
Storage capacity of up to 20, can remember the test conditions.
