usage

The instrument is mainly used in organic coating adhesion measurement in grid method. Applies in the laboratory, and also for the construction site under various conditions.

technical instructions

1, multi-blade cutter spacing respectively: 1 *0.*1 mm, 2 *0.*1 mm, 2.5 *0.*1 mm.

2, multi-blade cutter tooth tip straightness: 0.**3mm 0.**6mm.

3, the work of multi-blade cutter tooth tip width: 0.*5mm.

operation

1, the specimen must Prepared according to ISOR***4&ISO***8.

2, the sample placed on a plate with sufficient hardness.

3, hold the handheld to make the Cutter perpendicular to the sample plane.

4  cut with uniform pressure, smooth approach and the speed of ****0mm / S.

5, rotated the sample by *0 and repeat above operation to form a grid array graphics

6, measured with a soft brush on both sides of the diagonal grid array graphics gently, back 5 times, forward 5 times.

7, test at least three different positions on the sample, if the test results of three different positions differs, repeated more than three experiments, all results recorded.

8,cutting knife Replaceable.
