Which domestic abrasion tester is good

Product Name:Rubber floor chair caster wear tester

Product model: XK-5080

Usage description:

Rubber floor chair caster wear testerUsed for testing the wear resistance of chair casters on flooring (such as rubber flooring, PVC flooring, and polyvinyl chloride flooring), the instrument is strictly produced according to the standard GB/T4805 and controlled by a PLC touch screen. The machine consists of a rotating platform, a specimen support platform, casters, a driving mechanism, a lifting device, a fastening system, a speed counter, and a vacuum cleaner.

Execution standard: GB/T4085

Specifications:

Control mode: PLC touch screen

Load: 90kg

Platform diameter: ≥ 750mm

Material of sample support platform: hard plastic

Sample support platform: diameter ￠ 800 ± 5mm, thickness 7 ± 2mm

Wheel diameter of caster: ￠ 50 ± 2mm, width: 23 ± 3mm, crank distance: 32 ± 2mm

Wheel hardness: Shore A (95 ± 5) mm

Distance from caster to platform center: (198 ± 1) mm

Distance between 3 casters and the center of the platform: (130 ± 1) mm, distributed at 120 ° intervals, installation distance between any two casters: (225 ± 5) mm

Wheels test life cycle: 2 million cycles

Platform speed: (19 ± 1) r/min. After rotating for (180 ± 10) seconds, the platform stops and remains stationary for (5 ± 2) seconds, then runs in reverse.

Wheel speed: (50 ± 1) r/min

Result evaluation: After using the floor resistant chair caster grinding test machine to complete the test buckle, the entire specimen needs to be evaluated. The specimen should be observed from a 45 ° angle at a distance of 800mm from the specimen under a standard light source, and the observation table should be slowly rotated to observe whether there are delamination, cracking, joint detachment, and other damages in all directions of the specimen.

Experimental Procedure:

Clean the surface of the wheels with a cotton pad or paper dipped in ethanol and let it dry. Place the specimen support platform on the testing platform, ensuring that the holes on the specimen support can be bolted onto the testing platform. Slowly lower the caster until it contacts the specimen. Place the vacuum cleaner as close as possible to the test piece, but not in contact. Start the vacuum cleaner to begin the entire experiment.

Adjust the counter to the specified number of test cycles and start it. Products with substrates are required for testing. If the substrate is not specified, polyethylene foam with a thickness of (2 ± 0.5) mm and a density of (35 ± 5) kg/m3 shall be used as the substrate.

Use double-sided tape or adhesive tape to install the sample on the specimen support platform, ensuring that the double-sided tape or adhesive tape covers the entire specimen support platform. Ensure that there is no gap between the specimen and the top strip to prevent the specimen from moving or lifting under loading conditions. Set the counter to 25000 revolutions per minute and start it. After the machine stops at 25000 revolutions, check each layer of the specimen and evaluate the specimen after running for 25000 revolutions. Before evaluation, the 25000 rpm test piece should be cured for at least 24 hours under standard conditions, with the surface of the test piece facing upwards or hanging freely.
