Overview
JFL electric Pencil hardness tester model A-3086 is suitable for mobile phone shell, MP3/MP4 shell, notebook computer shell and other types of home appliance digital product shell lame plating hardness testing, as well as all kinds of metallic coatings, decorative materials, synthetic leather and other testing paints Hardness. The machine scratches on the film of the product with a certain Hardness label, and uses the hardest pencil label that does not cause film damage to indicate paints Hardness.
Features
1. The test angle is fixed at 45 ° to ensure test standardization
2. Provide a variety of load options (500g, 750g, 1000g) to adapt to different testing requirements
3. Test platform traverse speed adjustable range (0.5~ 10mm/s), knob adjustment and LCD display
4. Equipped with Fixed Sample Fixture to Ensure Test Stability
5. Meet many international standards
Principle
The machine scratches the surface of the film layer with a Hardness pencil to test the surface Hardness of the film layer. The Hardness pencil is fixed at a 45 ° angle, so that the front end of the pen center is in contact with the surface of the film layer, and the appropriate load is applied. The test platform is moved at a certain speed (JIS specification 0.5mm/sec) to move the surface of the film layer through the pen center. The softest pencil level where the film layer does not cause damage (scratches) can be regarded as the film layer Hardness.
Applications
Mobile phone shell, MP3/MP4 shell, notebook computer shell and other types of home appliance digital product shell lame plating hardness testing, various metallic coatings, decorative materials, synthetic leather and other testing paints
Standards
GB/T6739-2006、ASTMD3363、ISO15184、BS3900-E19、ECCA-T4／1、JIS、CNS
Steps
1. Place the entire machine horizontally
2. Adjust the speed to the lowest level, let the machine run normally, and then adjust the speed to the test demand value.
3. Clamp the sample to prevent loosening from affecting the test effect
Notice
• Be sure to place the entire machine horizontally before testing the machine
• Before testing, adjust the speed to the lowest level, let the machine run normally, and then adjust the speed to the test demand value
• The sample needs to be clamped to prevent loosening from affecting the test effect
• The panel part can be cleaned with stain removal oil
• The paint part can be cleaned with stain removal oil and pine perfume
• The fixture part needs to be wiped frequently to ensure that the product can be effectively and powerfully clamped
• Between the connecting rod and the connecting rod screw of the internal transmission structure, and between the two sliders and the linear bearing, the grease (industrial butter) needs to be replaced after half a month of normal use, and the original grease needs to be cleaned in advance
