BGD 500S Automatic Digital Pull off Adhesion Tester

Per eseguire in modo soddisfacente, i rivestimenti devono aderire ai substrati su cui vengono applicati. There are three different adhesion test procedures to assess the resistance of paints to separate from the substrate. The cross cut test, also described as cross-hatch, uses a blade to cut through the coating to the substrate. At least two cuts are made that intersect at 90 degrees to get a right angle lattice pattern. The cross-cut area is observed for any adhesion failure. The second method to test the coating adhesion is using a stylus or loop that an increasing amount of weight is applied until the coating is removed from the substrate. The third method called pull-off adhesion, measures the amount of tensile stress to pull the coating off the substrate. A dolly is glued to the coating surface, after the glue is cured, a testing apparatus is attached to the loading fixture and aligned to apply tension perpendicular to the test surface. La forza applicata viene gradualmente aumentata e monitorata fino al distacco di uno dei tappi di materiale di rivestimento, oppure viene raggiunto un valore specificato.

BGD 500/S automatical digital pull-off adhesion tester is a portable, strumento manuale utilizzato per misurare la forza necessaria per allontanare dal substrato un diametro di prova specificato del rivestimento utilizzando la pressione idraulica. La pressione viene visualizzata su un display LCD digitale e rappresenta la forza di adesione del rivestimento al substrato.

Valuta l'adesione (pull-off strength) di un rivestimento determinando la massima forza di strappo a trazione che esso può sopportare prima del distacco. Punti di rottura, dimostrato dalle superfici fratturate, si verificano lungo il piano più debole all'interno del sistema costituito da dolly, adesivo, strati di rivestimento e substrato.

AUTOMATICAL

◆ Originated in China, it can test automatically adhesion between coating and substrate by pull-off way and get good repeatable test results.

◆ Electronically controlled hydraulic pump automatically applies smooth and continuous pull-off pressure. Greatly reduces user effort and the risk of influencing the pulling process.

◆ Internal memory stores maximum pull-off pressure, rate of pull, tempo di prova, dolly size.

◆ Pull rate is controlled by PID closed-loop, stable and adjustable.

◆ Can set a constant pull force to judge if the coating could be separated from substrate under a certain force.

◆ 5.0 inch big touch screen, display pull-off force curve, operator can see clearly how it change throughout the test.

PRECISE

◆ Each PsiaTester’s pressure system is calibrated to within 1% accuracy by NIST traceable load cells
