Rotary Platform Double For Testing Lab Workshop.
Rotary Platform Double -
One of the methods used for determination of abrasion resistance of
textile materials or coated fabrics is the rotary platform method.
In
this test a test specimen is abraded using rotary rubbing action. The
test specimen is mounted on a horizontal circular platform and rotates
at a specified speed. Two abrasive wheels are made to rest on the upper
surface of the test specimen on either side of its centre. The wheels
rotate because of friction between them and the test specimen, thus
causing abrasion to take place. The wheels are loaded to apply the
desired contact force. Abrasion resistance of the test specimen is
evaluated either by finding the degree of abrasion after a specified
number of rotations of the test specimen, or by determining the number
of rotations needed to produce a specified degree of abrasion.
