gb/t 9279.1-2015 This section specifies a test method for determining the performance of a single coating or composite coating system with a single coating or composite coating scratch scratch with a stroke of loading load under the prescribed conditions. The needle is scratched to the bottom material, but in the case of the composite coating system, in this case, the needle can be scratched to the bottom material, or the middle coating can be scratched.
Scratch -resistant test machine > Working principle:
The needle is cut at the coating at a constant speed. Determine through the scratch scratch: whether the coating has been scratched to the specified degree (pass/does not pass test) for a single specified test load for applied; Essence
The test parameters are as follows:1. The geometric shape of the needle tip;
2. The range of the test load that can be adopted and increasing the increase in load;
3. Reduce the method of the height of the needle to the surface of the coating;
4. Run the acupuncture and scratch length. > Scratch -resistant test machine
The test report should include at least the following content:1. Identify all the necessary details of the test product;
2. Reference to this document (such as ISO 1518-1: 2019)
Third, all the details prepared by the test board, including the following:
1. The material, thickness and surface treatment method of the bottom material
2 The method of testing the coating to the bottom material. If it is a composite coating system, it includes the dry time and conditions between the coating
3. Time and conditions for baking) and aging (such as applicable)
4. The thickness of the dry coating, with micron meter, and the method in ISO 2808 used to measure the thickness of the coating. , And point out that it is a single coating or a composite coating system.
Four, > Scratching test machineThe type of needle used by
5. The load loaded on the needle during the test process, if it is applicable (pass/not passed/not passed the pass/not passed/not passed/not passed ”试验）
七、 Test results:
--- For each determination, whether the coating is scratched under specified conditions (pass/not passed)
--- or the low load of scratching the coating
8. Any difference between the test method of the specified test (through the provisions of the agreed or other methods)
9. Any exceptions observed during the test
Ten, Test date
1. Product introduction: >
Scratch Hardness Tests Also known as a balanced scraper with scratch resistance test machine, needle scratch test machine, scratch resistance test machine adapted to the insulation color coating single coating or single coating or Evaluation of scratch resistance performance of the composite coating system. Whether the ball -shaped steel needle is scratched or the steel needle has not cut through the coating with a certain weight to evaluate the scratch capacity of the coating. >
2. Product overview: > The scratch instrument is adapted to the insulation color coating single coating or composite coating Evaluation of scratch resistance of the layer system. Whether the ball -shaped steel needle is cut or steel needle is not drawn with a certain weight
The big load of the broken coating is evaluated Paddy resistance.
The automatic scratch instrument conforms to ISO1518, BS3900, ASTM D5178 and ASTM D2197 standards.
The conductor the bottom material can display the scratch and unprocessed curve on the screen in real time, and the test result directly displayed on the screen: Covering or unabatedEssence
