Overview
RONGJIDA LS Shakeout Wear resistance Tester, also known as shakeout abrasion tester, Falling Sand Abrasion Tester, is designed and manufactured according to the standards ASTM D968-83 and JG/T 133-2000. It is used to test the wear resistance performance of organic coatings under standard conditions. The abrasion amount per unit film thickness indicates the wear resistance performance of the coating on the test plate. The length of the tester is 36 inches (914mm), and the measurement is stable and reliable.
Features
1. Designed and manufactured according to ASTM D968-83 and JG/T 133-2000 standards, with reliable testing standards.
2, through the conduit abrasive falling from a specific height, abrasion amount of abrasion per unit film thickness to quantify the coating Abrasion Resistance, Measurement mode science.
The length of the catheter is 36 inches (914mm), the inner diameter is 19mm, and the structural design meets the test requirements.
4. Equipped with 3L volume funnel to meet continuous testing requirements.
5, the machine weight 25kg, Dimension 230 * 200 * 1500mm, compact structure.
Principle
LS shakeout Wear resistance Tester test coating Abrasion Resistance is through the conduit abrasive falls from a specific height to a good painting plate, until the plate substrate is exposed, the abrasion amount of abrasion per unit film thickness represents the abrasion Resistance coating on the plate.
Applications
Testing of wear resistance of organic coatings
Standards
ASTM D968-83、JG/T 133-2000
Steps
1. Test preparation: According to the standard requirements, the test plate is prepared at (23 +/- 2) ° C and the relative humidity is (50 +/- 5) % for 24 hours.
2, calibrated instruments:
(1) Pour a certain amount of sand into the funnel, check the sand flow falling from the lower end of the duct, and calibrate the device with the bottom adjustment screw until the center of the sand beam falls exactly at the center of the sand flow when viewed from two positions of 90 °.
(2) Use the height adjustment nut to adjust the distance from the pipe to the painted surface.
(3) According to the ASTM standard, when measuring in the vertical direction, the nearest point is 1 inch (25mm), the user needs to adjust according to his own sample thickness, and the machine adjusts 25mm in advance when leaving the factory.
(4) Pour in a certain volume of sand (preferably 2000 +/- 10ml) and measure the outflow time. According to the ASTM standard, the outflow rate should be 2L within 21s-23.5s. When tested with international standard sand, the measured speed is more than 7L in 1 minute.
Notice
• Before the test, it is necessary to prepare the test plate according to the standard and leave it under the specified temperature and Humidity conditions for sufficient time.
• The instrument must be calibrated before use, including the center position of the sand flow, the distance between the pipe and the test plate, and the outflow speed of the sand.
When adjusting the distance between the catheter and the painted surface, it is necessary to make accurate adjustments according to ASTM standards and the thickness of the sample.
• When testing, use sand that meets the standard, and control the Flow velocity of the sand to meet the test requirements.
