TOPCHANCES Hot Cross Hatch QFH Adhesive Force Measuring Instrument 1mm+2mm Adhesion Tester Hundred Grid Knife Suitable for GB/T9286-98,BS3900 E6/ASTM D3359
- This instrument and is designed and manufactured according to the standard of ISO2409-1992. Applicable to GB /T9286-98, BS 3900E6/ASTM D3359. The instrument draw the grid of a certain size by a certain specification of the tools by using the uniform force,cut and penetrate the coating to be a grid lattice graphics, to evaluate the adhesion of coating on the substrate through the assessment of the full extent of the grid.
- Uses :The instrument is mainly suitable for organic coating adhesion assay Hatch. Applies not only to the laboratory,the construction site can also be used under various conditions.
- Working principle and scope :The instrument is a certain specification tool that will make the coating lattice graphics cut and penetrate,hatch completed by six graphic classification, assess the effect of the coating adhesion separated from the substrate.
- Technical Specification :1.Multi-blade cutter spacing are: 1+0.01mm, 2+0.01mm. 2.Multi-blade cutter addendum straightness were: ≯0.003mm≯0.006mm. 3.Multi-blade cutter working tooth tip width: ≯0.05mm.
Instruction:
1.The specimen must be prepared according to ISOR1514 and ISO2828 requirements.
2.The test piece is placed on the tablet hardness sufficient.
3. Handheld Hatch handle, so multi-blade cutter perpendicular to the specimen plane.
4.With uniform pressure, steady approach does not vibrate and 20-50mm / S cutting speed cutting program.
5.The specimen is rotated 90 degrees on the cutting stroke cuts repeat the above operation,so as to form a lattice graphics.
6.With a soft bristle brush on both sides of the diagonal lattice pattern gently back 5 times.
5 times forward brush specimens.
7.The test at least at three different locations on the test piece is completed,if the test results of three different positions, the experiment should be repeated at more than three positions, all while recording the results.
To replace the multi-blade cutter, use a screwdriver blade Loosen the two screws, put the knives, knife blade attached to the handle side of the site, and tighten the screws.

Please Attention:
1.All cuts should be through the coating, but not too deep cut substrates.
2.As a result of the coating is too thick and hard and can not penetrate the material in the end,the experiment is not valid, but it should be stated in the test report.
3.The test must be a US company 3M tape produced 610-1PK special tape test(or otherwise specified test tape). The tape posted on the whole cross hatch, and then tore off the minimum angle, the result may be in proportion to the gum off the area determined according to the film surface.
4.The test should be carried out at a temperature of 23 Â± 2 â„ƒ and relative humidity of 50 Â± 5%.
