Overview
The Defelsko CHBLADE6X3 is a replaceable blade designed for cross-cut Adhesion Testers. The blade is made of hardened steel with 6 cutting teeth spaced 3mm to ISO 2409 for cutting a standard lattice pattern on the coating surface to evaluate its adhesion performance.
Features
1. Made of hardened steel, strong and durable.
It has six cutting teeth with a pitch of 3mm, meeting the ISO 2409 standard.
3. Each blade has four cutting edges, which can be turned over for extended test life.
4. Designed for use with the Defelsko cross-cut tester, it is easy to replace.
Principle
This blade is the core cutting component of the cross-cut Adhesion Tester. For testing, the blade is mounted to the tester and a crossed lattice pattern is formed by applying uniform pressure to cut specific spaced parallel scratches across the coating surface. The degree to which the coating is peeling off the substrate is then evaluated according to standard methods such as using tape disbonding, thereby quantifying its adhesion grade.
Applications
Coating adhesion testing, paints, coatings, platings, anti-corrosion layer and other surface preparation quality control and evaluation
Steps
1. Make sure the tester is in a safe condition and remove the old or damaged blade from the cutting head.
2. Align the CHBLADE6X3 blade with the mounting groove of the cutting head of the tester to ensure the correct direction.
3. Push the blade firmly in or install it in place to ensure that it is firmly fixed.
4. According to the test standard (ISO 2409) and the coating thickness to be tested, set the correct cutting spacing (3mm) and pressure on the tester.
5. Perform cross-cutting on the coating surface.
6. After the test is completed, if it needs to be replaced, carefully remove the blade.
Notice
• The blade is very sharp, so be careful when handling and replacing to avoid cuts.
• Use this blade only for cross-cut adhesion testing for its intended purpose.
• Ensure that the blade is firmly installed to avoid loosening during testing that affects the cutting mass or causes danger.
• When all cutting edges of the blade have been abrasion or blunt, the new blade should be replaced in time to ensure the accuracy of the test results.
Store properly after use to avoid blade damage due to collision with Miscellaneous hard objects.
• This product is a professional testing tool accessory, please operate under the guidance of non-professionals.
