The QHG pipe coating scratch Tester is designed according to the industry standard SY/T 4113-2007 "Scratch Resistance Test Method for Anti-corrosion Coatings". It is suitable for testing the scratch resistance of the anti-corrosion coating on the outside of the pipeline.
Operating Principle
The instrument is composed of servo motor and control system, and the test scratches are automatically completed and automatically zeroed. The scratching speed is maintained at 254mm/min, and the counterweight weight is raised and lowered freely to ensure that the marking needle parts fall freely on the workpiece.
Precautions
The instrument operation program has been set up at the factory, no need to change the program, after the power is turned on, put the test board, use the right round handle to fix it, manually open the rising button to make the test board rise close to the scribing needle, and then press the F key, automatic control, press the start button to complete the test automatically, press the start button to repeat the above actions, press the end program or exit key to exit.
[Note]Because the manufacturer's packaging may be updated or upgraded, the detailed packaging list shall be subject to the latest standard configuration of the manufacturer.
FAQ
QPipeline anti-corrosion coatings need to be tested for scratch resistance. What instrument is suitable?
A
QHG mar resistance tester is recommended. It is specially designed according to the SY/T 4113-2007 standard. It can simulate the real working conditions to scratch test the pipeline coating. The scratch speed controlled by the servo motor is stable at 254mm/min to ensure the accuracy and reliability of the results.
QHow to ensure the test Repeatability when doing coating scratch resistance test?
A
The QHG instrument has built-in automatic zeroing and programmed operation. After turning on and putting the test plate, press the F key to automatically complete the scratch and reset. The counterweight weight combination is flexible (5kg * 8 + 2kg * 2 + 1kg * 1), which can accurately control the scribing pressure and avoid human errors.
