Moisture resistant microbial penetration tester

Instructions for use of reciprocating abrasion tester

The reciprocating abrasion tester is used to test the scratch resistance and abrasion resistance of coatings, plastics, decorative fabrics, automotive interiors, pile fabrics, etc.

The LCD controls and displays the test process, and the parameters such as The Times of reciprocating wear, motion stroke, and reciprocating motion speed can be set according to the user's requirements.

The unique friction arm design can realize the replacement of different friction heads.

According to the lever balance principle precise control pressure implementation.

Fully meet the different requirements of different standards for friction form, friction head, pressure, etc.

Flatabrasion Tester for fabrics. An instrument to measure the "abrasion resistance" of a fabric (page 486).

It is a kind of flatting machine for fabric.

It is mainly composed of motion platform and bracket.

Linear reciprocating motion is generated by motor drive.

The fabric sample is installed with a certain tension on the moving platform.

Put the support bag tangling material (e.g. no. 400 water sandpaper) on the sample and rub back and forth.

Or wrap the sample around the bracket and flatten the abrasive on the moving platform.

When the support and the moving platform move relative to each other, the sample is subjected to reciprocating wear in the plane.

The wear resistance of the sample is determined by measuring the change of light transmittance and strength of the sample under a certain number of times.

1 Test Principle

The test sample is fixed on a horizontal sample table and is worn as the sample table moves horizontally under the specified abrasive and load.

The other end of the test arm is provided with weights to maintain the balance of the test arm to ensure the accuracy of the sample surface load.

abrasive

And the height of the load frame can be adjusted to suit the test of samples of different heights.

2 Test Criteria

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

The instrument is composed of the following parts: additional weight, friction head, balance bar, fixing knob, locking knob and balancing weight;

The LCD panel;

Power switch;

Emergency stop button.

Additional weights: Different additional weights are provided according to various standards and customer requirements. After adjusting the balance, the weight of additional weights is the weight pressed on the sample.

Friction heads: According to different standards and customer requirements, there are a variety of friction heads available for replacement.

The instrument is equipped with a friction head and its fixtures as follows: where, for the D42 1775 grinding head, sandpaper shall be attached to the circular surface of the grinding head during use.

For rubber mounting grinding head and sleeve, it is necessary to disassemble the sleeve during use, put the green grinding head into the middle of the sleeve, and then use the top wire to protrude and tighten, and the grinding head shows the surface of the sleeve 0.1in.

Fixing knob: loosen the fixing knob. If the weight of the balancing weight and the friction head cannot reach the balance, the balance bar will tilt.

Conversely, if the fixed knob is locked, the current position can be locked even if the balance bar is unbalanced.

Lock knob: after tightening, the ratio of the balance bar to the front can be locked.

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

Balancing weights: According to the principle of lever balancing, move the front and back positions of the balancing weights to balance with the friction heads.

To make the added weight pressure equal to the pressure applied to the actual fabric.

LCD: it can set test parameters, display and control the test process.

Power switch: Start or close the instrument.

Emergency stop button: In case of emergency, press the emergency stop button to shut down the instrument.

The utility model relates to a workpiece wear resistance test device, in particular to a reciprocating wear resistance test instrument.

Setting skills:

Processing parts processing factory has wear-resisting requirements to check its abrasion resistance, the current general way is to manually file flat grinding, such defect is efforts in manual way to grasp, the distance and the speed of conflict and conflict is different, every time the artificial error count simple troubled, fixed the unstable simple azimuth change by hand.

These problems lead to the conflict test can not truly and accurately reflect the wear resistance of the workpiece

Content of utility model

According to the shortage of the above existing skills, the skill problem to be dealt with by the utility model is to provide a reciprocating wear resistance test instrument, which can easily and accurately carry out the wear resistance test of the workpiece.

Mentioned in the utility model of a reciprocating abrasion tester, contains the workbench, the workbench is the very top clamp and lifting control organization, the rise and fall of elevator control organization stem component fixed set a workpiece conflict, the conflict of artifacts component contains a built-in motor, motor in order to connect with the crankshaft and connecting rod, connecting rod bottom fixed set a slide rail, slide rail set on the slider, slider to a file at the bottom of the fixed support, file support a built-in file, meanwhile, a file with that of the fixture is below;

The table is built-in with photoelectric counter and the control circuit connected with the motor and fixture. The surface of the table is set with photoelectric counter control panel, fixture control switch, motor control switch and power supply switch.

Meanwhile, the file is preferably a triangular file.

When one plane of the triangular file is worn, it can be replaced on the other two planes, increasing the operating power.

The fixture is preferably provided with a rubber pad.

It can not only fix the workpiece usefully, prevent the workpiece from falling in the process of conflict, but also prevent the workpiece from being caught.

The jig preferably includes a screw rod and a clamp block. One end of the screw rod is processed with forward thread and the other end is processed with reverse thread.

By rolling the screw, the two clamps move in opposite direction at the same time, which ensures the center of different workpiece of different length is always unchanged.

The working process of the utility model is (I) turn on the power switch and set the photoelectric counter to zero;

(2) Adjust the lifting of the tissue, raise the file;

(3) Adjust the fixture control switch to make the fixture clamp the workpiece;

(4) Adjust and lift the organization, lower the file, and press the workpiece;

(5) Set the counting times of photoelectric counter;

(6) Start the motor control switch and start the test.

The utility model has the beneficial effect that the conflict velocity is constant, the conflict intensity and the number of conflicts can be controlled usably, and can truly reflect the wear resistance of the workpiece, greatly improving the working power.
