1.The introduction of falling sand wear testing machine:

    The falling sand wear-resisting testing machine is made of stainless steel, beautiful and durable, used to test the wear resistance of organic coatings under standard conditions. The wear resistance of the coating on the test plate is expressed by the wear amount per unit film thickness. Falling sand testing machine is a professional testing instrument, testing methods in line with the American industrial standards ASTM D968-83 and JG/T 133-2000 standards. This method tests the wear resistance of the coating by dropping the abrasive onto the coated test plate from a specified height through the catheter until the ground material of the test plate is visible. The wear resistance of the coating on the test plate is represented by the amount of wear per unit film thickness.

2.The working principle of falling sand wear-resisting testing machine:

The working principle of the falling sand wear-resisting testing machine is that the standard sand through the pipe from the specified height free to wash the paint film on the surface of the sample, straight grinding to expose the diameter of 4mm test plate substrate. The wear resistance of fluorocarbon-coated aluminium alloy building profiles and of paints, varnishes, sprays and related products was determined by the volume (L) of abrasive material used to wear the paint layer per unit thickness.

2. The technical parameters of falling sand wear-resisting testing machine:

1. Catheter Length: 36 inches (914mm)

2, pipe diameter: 0.75 inch (19mm)

3, funnel volume: 3L

4, overall size: 230mm × 200mm × 1500mm (length X width X height)

5, the machine weight: 25kg

6, funnel Angle: 60°

7, sample frame Angle: 45°

3.The use of falling sand wear testing machine:

1. Step 1:

Mark three circular areas on each test board, each with a diameter of 1 inch (25mm), so that the test board can be properly positioned on the test board bracket of the falling sand wear testing machine. According to the standard test coating thickness, each area has at least three test points, recording the average coating thickness on the respective area.

2. Step 2:

The coated test plate clamp is fixed on the support of the falling sand wear resistance testing machine test plate, adjust the falling sand wear resistance testing machine test plate so that the marked area is just below the center of the conduit, pour a certain volume of standard sand into the funnel, open the falling sand switch, make the sand through the conduit, impact on the falling sand wear resistance testing machine test plate, at the bottom of the falling sand wear resistance testing machine with a container to collect the falling sand. Repeat until a 5/32 inch (4mm) diameter area of the coating is exposed to the substrate. In the process of falling sand wear-resisting testing machine, the appropriate incremental sand is 2000 ml 10mL. When approaching the end point, 200 ml 2mL sand can be added to the funnel.

4. Falling sand wear testing machine points for attention:

1. In order to ensure that the heart of the sand bundle is just the center of the falling sand flow, the alignment of the falling sand wear-resistant testing machine conduit should be checked every once in a while.

2, sand through the falling sand wear-resisting testing machine 25 times, to use N0.30 sieve will be fine sand removed, sand used 50 times to replace.

3. In order to obtain the highest precision test results, both parties shall use sand from the same source.

4, the test should pay attention to, after the end of the sand, the sand wear resistance testing machine should be slightly tilted, so that the bottom of the funnel in the small box of the excess sand poured out, and then put into the sand switch, so as to avoid the sand switch can not be put into.

Warm tip: Due to the continuous upgrading of the falling sand wear testing machine, falling sand wear testing machine pictures for reference only, details email consultation! More quality products welcome your consultation!
