The Taber Wear Resistance Testing Machine can be used to test the wear resistance performance of semi-rigid polyvinyl chloride flooring. Qisnun Precision Electromechanical Technology Co., Ltd. is a manufacturer who can provide customers with various solutions to solve the required problems.
GB4085-2015 entered into force on 2016-08-01. This is the \"semi-rigid polyvinyl chloride floor\" test method. This standard specifies semi-rigid polyvinyl chloride flooring. (hereinafter referred to as floor) terms and definitions, classification, grades and marks, requirements, test methods, inspection rules, signage, transport and storage.
Component composition:
1. Horizontal rotary test stand: diameter is greater than 105mm , the top surface is horizontal, and can be placed Specimen. The test bench can rotate around the central axis.al at a speed of 60 ± 2 rpm.
2. Two cylindrical grinding wheels wrapped with leather sheets: the grinding wheels are made of metal or hard plastic, with a diameter of 42mm and a width of 12.7mm, and can rotate freely around a fixed axis. The piece of leather wrapped on the wheel is about 13mm wide and 4mm~5mm thick. Place a steel ball with a diameter of 10 mm on the leather and load it with a load of (10 ± 0.1) N. After 30 seconds, the leather piece should have a residual depression of 0.3 mm to 0.5mm. Leather wrapped wheels require 500 rounds of 240 grit sandpaper before first use. The two wheels can form a circular track on the surface of the specimen, with an area of about 3000 mm2. When the diameter of the grinding wheel wrapping the leather sheet is less than 44.4 mm, the grinding wheel must be replaced.
3. Spin Counter: After reaching the set number of spins,the rotating platform can automatically stop rotating.
4. Container: The upper end is open and can hold at least 200g of abrasive. There is a height-adjustable shake-out tube at the bottom of the container. The bottom of the shakeout tube is (10 ± 3) mm from the specimen surface and can be closed quickly.
5. Vacuum cleaner: It can absorb abrasives and crushed particles.
