The latest fourth-generation automatic circle marking tester developed by Truit is a device used to evaluate the adhesion between coatings and substrates. It complies with the requirements of GB/T 1720 standard, and evaluates the adhesion of coatings by continuously drawing many circles of the same diameter on the coating to be tested, which overlap each other at a certain distance, and then evaluating the adhesion of coatings based on the area of the intersection of the circles.
· Aerospace aluminum alloy body: The equipment is made of aerospace aluminum alloy, which is beautiful, light and corrosion-resistant.
· High-definition touch interface: The 4.3-inch visual touch screen gives the instrument a modern and professional appearance and simplifies the operation process.
· Automatic judgment prompt: The indicator light automatically judges whether the needle has scratched the coating to the substrate, ensuring the accuracy and convenience of operation.
· Electric circle drawing: The circle drawing is completed electrically, with uniform speed and constant force, ensuring high repeatability and comparability of the test results.
· Pioneer in industrial automation: The starting and end points of the working platform are accurately positioned to strictly ensure that each test can reach the standard stroke.
· Flexible adjustment of stroke and speed: Both the stroke (20~80mm) and the speed (10~120±1 rpm) are adjustable.
· Sliding platform: Convenient for multiple tests at different positions on the same test plate.
· Precision positioning dual guide rail system: More stable than single guide rail guidance.
· Guide rod type needle lifting structure: Convenient for replacing the needle and test plate, and can adapt to test plates with a wider range of thicknesses.
·Double nut adjustment screw: ensures smooth platform operation, reduces errors, and improves data accuracy.
·Carbide thread: Ultra-precision carbide thread accurately controls the circle diameter to ensure more stable test results.
· Quick tool assembly and disassembly: The tool needle assembly and disassembly are convenient and fast, saving time and improving efficiency.
·Customized weight combination solution: Use multi-level weight combination to get the appropriate weight load to meet different test requirements.
·Scale-type convenient needle adjustment assembly: The circle diameter can be manually adjusted without the need for additional tools.
· Radius of rotation: R=5.25mm
· Circle length: 20~80mm (adjustable)
· No-load pressure: 200g
· Weight: 100g, 200g, 500g
· Scratching needle: Tip radius (0.05±0.01) mm, angle 25°
