RCA paper tape wear Tester is a paper tape wear Tester of the American Norman Tool brand. It has a good ability to perform friction tests on tiny letter surfaces and uneven surfaces. Therefore, it is widely used in the wear resistance test of plastic surface coatings. Mobile phone button printing, mobile phone casing, MP3, CD player, laptop computer, PDA, computer casing and other products. The RCA Tape Rubbing Machine provides a quantitative statistical method for differences in the level of abrasion resistance of various coatings and surfaces. It has the functions of stopping when the number of times reaches and stopping when the paper breaks, which can reduce the error of the product wear test and save paper for customers when testing.
The specific working principle of RCA paper tape wear machine is as follows:
① Use a special RCA paper tape as the friction medium, and act on the friction head with a fixed load. The friction head drives the rotating paper tape through a fixed-diameter roller and a constant-speed motor, and continues to apply force to the surface of the sample until it sees The surface substrate may reach a certain degree of wear, and the friction resistance of the test sample shall be evaluated by the number of motor revolutions displayed by the counter.
②For the softer material, the load is reduced by 55g or 175g, and two sample fixing methods are optional, suitable for flat or 3D samples.
③A light-type magnifying glass is attached to check the counter to get the wear result. Counting method: GD-7-IBB type with rotary mechanical counter, GD-7-IBB-CC type digital counter (LCD display, 0~999,999 can be set as required revolutions).
④ Loads of 55g, 175g, 275g (Note: the scale test load is 275g, no weight reduction weight is added to the lever), with two weight reduction weights attached, the test load can be reduced to 175g or 55g.
A. Universal Sample Holder
B. Universal clip-on sample holder
C. Magnifying glass with light
D. Winding reel device
E. Spirit level, used to adjust the level of the machine
F. Sliding bolt, used to confirm whether "H" is parallel to the base of the instrument, and set "Z" (surface gauge, indicating parallel to the instrument). When the "O" ring and test paper are placed in the test area, it is necessary to confirm whether In line with parallel, the sliding bolt must be moved out from under the rocker arm "H" during operation.
G. Revolution counter
H. Swing arm
I. Cam shaft screw
J. Vertical axis fine adjustment screw
K. Vertical axis, the position can be adjusted
L. Dust cover
M. Clamp screw on the rocker arm (for changing the vertical axis angle) The vertical axis angle has been fixed before leaving the factory, please do not loosen it for adjustment, please refer to the precautions.
N. Nylon paper guide wheel frame, used to guide paper and tape without any adjustment.
OO rings, worn out or need to be replaced after six months of use.
P. Sample stage, fixed flat sample
Q. Aluminum supply reels with 11/16" wide abrasive tape (FedeRAL Spec. # UUT00126E)
R. Two weight reduction weights are installed on the left rear of the rocker arm, so that the sample can bear a load of 55 or 175 grams.
S. Manual switch
T. 1/4" wide abrasive paper tape for testing concave and elongated letters
U. to be determined
V. Hexagon wrench set
W. Pressure roller
X. Drive roller
Y.1/8 thick sheet (in an accessory box)
Z. Surface gauge to indicate that the sample is parallel to the surface of the instrument base
