The Taber Abrasion Test Principle And Procedure

Strengthening control, the tests on the vamp material selected material with highwear resistance strength to the top of the shoe, shoe, such as easily damaged parts, in raising the overall durable performance and service life of shoes is of great significance. taber abrasion and wear tester and double-head taber abrasionand wear tester  have been recognized by more and more domestic and foreign customers because of its advantages such as simple operation, stable result and wide application range.


Taber Abrasion tester Test principle
Be placed on a rotating platform test samples, through the rotating platform as the above two rolling friction wheel, friction wheel under certain load and the specimen for rotating friction movement to wear. One friction wheel is outwards, and another friction wheel is in the inner friction sample. The abrasion marks are an overlapping ring. After the specified friction winding number, according to the surface wear condition and color change degree, the grading evaluation.

Test conditions
In temperature (20 + 2) ℃, humidity (65% + / - 5%) under the condition of test. Before the test, the sample should be placed in the standard environment of GB/ t22049-2008 standard environment for the environmental regulation and testing of shoes and shoes, and adjust the above 4h.

Abrasion and wear Tester test procedure
Fix the sample face up on the rotating platform and install the selected grinding wheel on the support pressure bar.
After selecting the appropriate load, put the support lever down, make the grinding wheel contact with the sample surface, connect and open the dust collecting device.
Start the instrument and test the number of cycles set by the counter. For vamp material, the number of friction is used 500 times.
After the test, remove the sample, check and record the abrasion of the sample, and use of the grey CARDS according to GB/T250-2008 "textile color fastness test assessment change color with the grey CARDS" qualification test area changes color and color fastness rating.

How To Process The Elmendorf Tear Strength Test

The Elmendorf tear tester has been developed specially for the paper industry and is outstanding for simplicity of operation and high measurement accuracy. The exchangeable pendulum is equipped with a pneumatic sample clamp. The initiation and return of the pendulum, as well as sample cutting is completely automatic. The device is operated via an integrated touch screen, where the test method can be selected, specific settings can be adjusted, and, after the measurement, results and statistics can be  displayed.Each pendulum is supplied with the appropriate control weight so that, with the help of the service program, it can easily be checked for functionality and balance. The Elmendorf tear test Procedure:     Cotton fabric was taken.     Warp and weft direction of the fabric was identified.     Two strips were cut from the fabric in both directions having dimensions of 100 x 63.5 mm.     The sample was then fixed in the jaws of the ...

The Scratch Tester Working Principle From Qinsun LAB

The scratch test machine is used to evaluate the shear, scratch, planing, scraping and engraving performance of the material. Its applications include rigid organic materials, plastics and glass, and so on. The test parameters, such as the speed of scratches, the length of scratches, the distance between scratches and the number of lines, are the test equipment with strong applicability and convenience. scratch tester Working principle: Coating has three aspects: the action of protection, decoration, and hide the defects of products, and the three main hardness has a lot to do with paint, paint film hardness is said film one of the important properties of mechanical strength, is an important indicator of measuring coating product quality, and measure the coating hardness is an important index of the scratch resistance of determination; Coating good product in the process of packaging, transport and use will draw by hard brush, not row brush the paint film is often leave scratc...

Correct Use Of Color Assessment Cabinet

Observation Angle: The following points are all the facilities required for the Color Assessment Cabinet , and the viewing Angle will directly affect the evaluation results. According to international standards, there are only two observable angles that can be used. They are: A, zero light source and 45 degrees observation (0 °, 45 °), the light from zero (vertical) incident Angle on the sample, sample watchers from 45 degrees. B, light source and 45 ° inclined channel 45 degrees of light source, zero observation (0 °, 45 °), the layout must use specific 45 degrees of inclined (45 ° Fixed Angle table) making from 45 degrees of light source on the samples, sample watchers from zero (vertical). The location of the 45 ° light samples: Regardless of any of the above observation methods, it is important to note that the test sample is placed in the middle of the light box as far as possible to reduce the influence of the external light source. In addition, the most important thing...
