Overview
The new standard coating brush resistance tester is designed and manufactured according to the provisions of the new GB/T 9755-2014 standard, and is used to evaluate the washing resistance performance of coatings. When used, it can also evaluate the performance of any film composite treated surface, such as paints, Eletroplating, baseplate, overlay, wood density, etc. The device washes the coating on the standard test board, and the number of washes can be directly read by the counter. According to the number of washes, the importance and necessity of coating washing resistance performance testing can be assessed. It is a testing instrument required by paint manufacturers and paint research departments.
Features
1. Designed and manufactured according to the new GB/T9755-2014 standard;
2. It can evaluate the washing resistance of the surface treated with paint and film;
3. The number of washes is directly read out by a 4-bit counter;
4. Suitable for a variety of surface forms, such as paints, Eletroplating, baseplate, overlay, wood density, etc.;
5. It is a necessary testing instrument for paint Manufacturers and Research Departments.
Principle
The instrument uses a motor-driven brush to reciprocate the coating applied on the standard test board. The washing Travel is 300mm, the scruf speed is 37 +/- 2cpm, and the number of washes is directly recorded by the counter. According to the number of washes, the washing resistance performance of the coating is evaluated.
Applications
Paint production, paint research, paints surface, Eletroplating surface, baseplate surface, overlay, wood density surface
Steps
1. Prepare a standard test plate with a size of 450 * 165mm.
2. Install the test plate on the instrument.
3. Start the instrument and wash the brush at a speed of 37 +/- 2cpm;
4. Directly read the number of washes through the counter;
5. Evaluate the washing resistance performance according to the number of washes.
Notice
Make sure the power supply is 220V 50Hz.
• The brush weighs 450g, pay attention to safety when using it;
• The size of the test plate must meet the 450 * 165mm specification;
• Follow the GB/T9755-2014 standard requirements during operation;
Maintain motors and counters regularly to ensure accuracy.
