Introduction of multi-function reciprocating abrasion tester

The multi-function reciprocating abrasion tester is used to test the resistance to scratch and abrasion of coatings, plastics, decorative fabrics, automobile interiors, velvet fabrics, etc. LCD control and display the test process, can be set according to user requirements reciprocating wear times, motion travel, reciprocating speed and other parameters. Unique friction arm design, the realization of different friction head replacement. The implementation of precise pressure control according to lever balance principle. Fully meet the different requirements of different standards for friction form, friction head, pressure, etc.

1 test principle

The test sample is held on a horizontal bench and worn down as it moves horizontally with the specified abrasives and loads. The other end of the test arm is equipped with a weight to maintain the balance of the test arm to ensure the accuracy of the sample surface load. abrasive

And the load rack height is adjustable to suit the test of samples of different heights.

2 test standards

ASTM F2496, ISO 1518-1, ISO 1518-2, GME 60248, D42 1775, etc

The instrument consists of the following parts: additional weight, friction head, balance bar, fixing knob, locking knob, and balance weight; The LCD panel; Power switch; Emergency stop button.

Additional weights: different additional weights are equipped according to different standards and customer requirements. After adjusting and balancing, the weight of additional weights is the weight pressed on the sample.

Friction head: according to different standards and customer requirements, there are a variety of friction head can be replaced. The instrument is equipped with friction head and its fixture as follows: for the grinding head of D42 1775, sandpaper shall be attached to the arc surface of the grinding head during use. For rubber mounting grinding head and sleeve, the sleeve shall be disassembled in use, the green grinding head shall be placed in the middle of the sleeve, and then the top wire shall be used to highlight and tighten it, and the grinding head shall be exposed to the surface of the sleeve 0.1in.

Fixing knob: loosen the fixing knob. If the balance weight and the weight of the friction head cannot reach the balance, the balance bar will tilt. On the contrary, if the fixed knob is locked, the current position can be locked even if the balance bar is not balanced.

Locking knob: after tightening, the front and rear ratio of the balance bar can be locked.

Balance bar: to measure whether the lever balance and support connection.

Balance weight: according to the principle of lever balance, move the front and rear position of the balance weight to balance with the friction head. The pressure applied to the weights is the pressure applied to the actual fabric.

LCD: it has the functions of setting test parameters, displaying and controlling the test process.

Power switch: start or turn off the instrument.

Emergency stop button: in case of emergency, press the emergency stop button to turn off the instrument.
