Rotary | Triple | Film cross-cut device / 100 grid knives / Adhesion Tester / blade / with tapeProduct Introduction: According to ISO2409-1992 standard design and manufacture.It applies to GB / T9286-98, BS 3900 E6 / ASTM D3359.Feature: Uniform set aside for certain sizes of squares within squares by assessing the full extent of the film coating on the substrate to assess the degree of adhesion to 'level' means. It is mainly used in organic coatings grid method adhesion determination, not only for the laboratory, can also be used for the construction site under various conditions.Use:The instrument is mainly applied to the organic coating Crosshatch adhesion assays not only for laboratory, can also be used for the construction site under various conditions. Work principle and scope:The instrument with certain specifications tool that will make the coating lattice graphics cut and penetrate, cross-cut by six complete graphical classification, assessment resistant coating from the substrate separation. Technical Specifications: Multi-blade cutter spacing respectively: 1 + 0.01mmL, 2 + 0.01mm, 3 + 0.01mm. Multi-blade cutter teeth were top straightness: ≯0.003mm≯0.006mm. Multi-blade cutter tooth tip width work: ≯0.05mm. Tooth spacing: 1mm blade: Film thickness: 60um or less 2mm blade: Film thickness: 120um or less 3mm blade: Film thickness: More than 120um Operation and use:The specimen must be prepared according to ISOR1514 and ISO2808 regulations. The test piece is placed flat on a sufficient hardness. Handheld cross-cut handle, make multi-blade cutter perpendicular to the specimen plane. With uniform pressure, balanced approach and does not vibrate 20-50mm / S cutting speed cutting program. The degree piece rotation 90 °, on the cut cutout draw repeat the above operation, so as to form lattice graphics. Use a soft brush to measure two diagonal lattice pattern gently back five times, 5 times forward brush specimens. Test at least three different positions on the specimen is completed, if the test results of three different positions, the test should be repeated in more than three positions, while recording the full results. To replace the multi-blade cutter, a screwdriver blade body will loosen two screws, put the knives, the knife edge portion attached to the handle side, tighten the screws. Precautions:All the incision should be through the coating, but cut into the substrate can not be too deep. As a result of the coating is too thick and hard and can not penetrate the material in the end, the test is not valid, but it should be noted in the test report. Determination must be compatible with the tape in exceptional circumstances or when there are special requirements 25mm wide tape is generally translucent tape backing material is polyester film or cellulose acetate. The tape affixed to the entire cross-hatch, then a minimum angle tear The results can be based on the film surface is rubber fall in proportion to the calculated area. The test shall be carried out at a temperature of 23 ± 2 ℃ and relative humidity of 50 ± 5%. Adhesion testing standards: ISO Level ASTM grade Test Results 0 5B Cut edge is completely smooth, without any flaking lattice edge. 1 4B At the intersection of the cut a small piece of peeled, cross-cut area is not more than 5% of the actual damage. 2 3B Edge and / or incision of the intersection has been peeled off, the area of more than 5% but less than 15%. 3 2B Along the cut edge of a large portion of peeling or flaking whole, and / or part of the entire grid is flaking. By peeling area of more than 15%, but less than 35%. 4 1B Cut edge large flake / or some portion or all of the peel grid, an area larger than draw 35% of the grid area, but not more than 65%. 5 0B Over to the next level.
