Overview
INKS printing wear resistance tester (model: PY-H618) is used to test the Abrasion Resistance of printing ink layer, PS version photosensitive layer Abrasion Resistance and surface coating Abrasion Resistance of related products. Effectively analyze the problems of poor rubbing resistance of printing products, ink layer peeling, low printing resistance of PS version and poor coating Hardness of other products, and judge the Abrasion Resistance of ink layer (or coating) by measuring the reduction of density before and after friction (or the reduction of Coating thickness).
Features
1. The instrument is designed in strict accordance with standards, effectively ensuring the accuracy of test data
2. The rubber test speed is an integrated precision grinding machine sanding, the test process is stable without abnormal jitter, the embedded standard friction table ensures a uniform friction area, and the friction process is completely silent
3. Adjustable setting of friction times for accurate testing, and automatic stop after the test is completed
4. The counter automatically records the number of frictions
5. The sample clamping fixture is simple and can install the sample more quickly and conveniently
Principle
According to the friction load of international standards, the paper, Cardboard, leather and other sample printing products are rubbed back and forth at a specified speed to test the adhesion of inks, and the reduction of density (or the reduction of Coating thickness) before and after friction is measured to judge the Abrasion Resistance of the ink layer (or coating).
Standards
GB/T7706、ASTM D 5264、TAPPI-UM486、JIS 5071-1
Steps
1. Adjust the number of friction settings
2. Install the specimen on the fixture
3. Start the test, and the instrument automatically records the number of frictions
4. Automatic stop when the test is completed
5. Coating thickness reduction before and after friction measurement
