Overview
YONGLIDA NM-1 wear resistance tester is a multi-functional dry abrasion tester, which does not need to add chilling down liquid, does not produce more dust, and does not need a vacuuming device. The instrument adopts a professional control system, which is simple, convenient and reliable. It can perform wear resistance tests on various coatings and substrates as needed, and evaluate its abrasion resistance performance by evaluating the degree of abrasion.
Features
1. Adopt dry abrasion method, no need to chill down liquid and vacuum device.
2. Professional control system, easy to operate, convenient and reliable.
3. Coatings and substrates can be tested for wear resistance.
4. The number of abrasions is directly read by the counter, which is convenient for quantitative evaluation.
Principle
The instrument performs reciprocating abrasion on the surface of the test plate under a set load by means of linear friction. According to the added weight weight, the number of abrasions and the degree of abrasion on the surface of the test plate, the abrasion resistance performance index of the Coating or substrate is comprehensively evaluated.
Applications
Coatings, paints, paper, wood and other coatings and substrate wear performance test
Steps
1. Prepare the Coating or Substrate Plate to be Tested.
2. Select the appropriate abrasion material according to the test requirements and install it.
3. Set and apply the required weight on the instrument.
4. Set or record the required number of frictions through a counter.
5. Start the instrument for a linear reciprocating friction test.
6. After the test is completed, read the number of abrasions displayed by the counter.
7. Observe and evaluate the degree of abrasion on the surface of the test plate.
Notice
* Power supply voltage is AC 220V 50Hz.
Select the appropriate friction load and frequency according to the test material.
Check whether the components of the instrument are firmly installed before operation.
During the test, pay attention to the operation status of the instrument.
* Regular maintenance of the instrument to ensure test accuracy.
