Testing principle and operation method of RCA tape Wear testing machine

RCA paper tape friction machine has a good ability in the friction test of small letter surface and uneven surface, so it is widely used in the wear resistance test of plastic surface coating, mostly used for mobile phone key printing, mobile phone shell, MP3, CD player, laptop computer , PDA, computer case 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 test principle and operation method of the American RCA paper tape wear Tester with Figure 1

Test Principle

① Use a special paper tape as the friction medium, and apply a fixed load to the friction head. 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 the surface is visible. The substrate may reach a specific degree of wear, and the anti-friction performance of the sample is 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.

operation method

1. Roll the unoiled paper or tape to rub against the sample and judge its abrasion effect at a certain number of revolutions

2. For soft materials, reduce the load by 55g or 175g

3. Comes with a magnifying glass to view

4. Counter: digital counter (LCD display, 0-9999 can set the number of revolutions)

Precautions

①Unified samples are tested under different friction media, and the number of rotations obtained will vary greatly. The use of a specific paper tape is the key to ensure the reliability of the test data.

②After unpacking and using, moisture-proof measures should also be taken to ensure the good condition of the test tape.
