Description:

According to ISO2409-1992Design and manufacture of standard. Applies to GB/T9286-98, BS 3900 E6/ASTM D3359.

Uses: . The instrument is mainly applied method determination of adhesion of organic coatings. Not only for the laboratory, can also be used for a variety of conditions of the construction site.

Working principle and application

The instruments to a certain specification tool coating array graphics cut and penetration, cross cut the finished graphics according to six categories, evaluation of coating adhesion effects of separation from substrates.

Technical instructions

1, Multi-edged cutter spacing are as follows: 1+0.01mm , 2+0.01mm.

2, Multi-bladed cutter tooth tip line are as follows: ≯0.003mm ≯0.006mm.

3, Multi-edged cutter teeth width: ≯0.05mm.

Operation and use

1, Specimens must be ISOR1514And the ISO2828Preparation of the provisions.

2, The specimen is placed in a hard enough on the plate.

3Hand cross cut handle, blade cutting perpendicular to the film plane.

4, With uniform pressure, smooth no fibrillation technique 20-50mm/S Cutting speed cuts.

5, Rotate the specimen 90Degrees in the repeat cut on the cut, so that the form array graphics.

6With a soft brush graphics on either side of the diagonal gently 5Time to move forward 5Brush specimens.

7Test specimen of at least three different positions to complete, if test results for three locations should be repeated more than three locations, recording all results.

8And if you need to replace the blade cutters, use screwdriver to unscrew two screws on the cutter body, put on the knife, stuck to the blade positions on one side of the handle, screw tight.

Matters needing attention

1All cuts should penetrate the coating, but cut into the substrate must not be too deep.

2If thick and cannot penetrate the hard material coating, then the test is not valid, but should be described in the test report.

3Test tape must be United States 3MCompany production 610-1PK Special tape for testing. Put tape on the entire cross cut and tear off at the minimum angle, results can be based on the paint film surface is falling area ratio is obtained.

4, Experiments at temperatures 23 ± 2℃And relative humidity 50 ± 5%In the
