The electric cross hatch tester is used to conduct various scratch and scratch resistance tests on the surface of paints and coatings to determine the adhesion properties of paints and coatings. This is a test independently developed and produced by qisnun Precision Mechanical and Electrical Technology Co., Ltd. Equipment, cost-effective and comprehensive after-sales service.
Parameter requirements:
1. Instrument power supply: 115/230 VAC, 50/60 Hz (please ask for voltage when ordering)
2. Equipment power supply: 400W
3. Specimen specifications: 80 × 50 mm
4. Sample thickness: 0.5~20 mm
5. Standard load range: 2~50N (2N rounded)
6. Special load range: 1~10N (1N increments) (optional accessories required)
7. Engraving path: 25 or 45 mm
8. Leveling speed: 1 m/min or 40 mm/s
Applicable test:
Cross-scoring test:
Area test can be performed according to general standards without additional procedures. following cross marking method can be selected (number of stripes × cutting distance in mm). 2×5, 6×1, 6×2, 6×3, 8×1, 8×2, 11×1, 11 ×2.
The marking system uses a hard metal tip to cross-mark continuously and automatically at a marking speed of 40 mm/s. Rotate the specimen 90° and repeat the marking to complete the cross marking. The load requirements for scratching the coating on the substrate can be found during a scratch test.
The adhesive tape should be peeled off when marking and marking analysis of some standards. Adhesive tapes will also be provided to customers as accessories to meet the requirements of EN ISO 2409 (tape width 25 mm, adhesive force 10 ± 1 N). Delivery includes u2.5x magnifying glass for evaluation of markings. In most standards, appearance quality can be compared visually using a standard scale (rating scale).
Although adhesion tests using the scoring method can be compared with each other, they are not suitable for comparison with the results of another test method (such as vertical separation test EN 24 624). Because they are different processes.
Anti-scratch test:
For anti-scratch test according to GME 60280, select a knife head of φ1 mm and a predetermined grid spacing (20 blades apart 2 mm). The pressure is the same as the cross hatch test, 5N, and the speed is 1 meter/minute.
When analyzing the scratch resistance test, the difference of △L shell is compared to the undamaged plastic surface. The one who can meet this requirement is the light sourcelighting D65 and the geometric angle measurement hole d/8 φ27mm.
As an enterprise integrating R&D, manufacturing, sales, training and service, Shanghai Panbiao Textile Testing Technology Co., Ltd. is committed to continuously providing more testing instruments to the market and providing long-term testing instruments for textiles, leather, combustion, automobile interior materials, environmental climate aging, masks, etc. Non-standard customization is also accepted and all are processed before purchase. Targeted tests can be carried out according to customer requirements to ensure that the purchased instruments are suitable.
