BGD 568 ISO 17132 ASTM D 4145 T-Bend Tester Manual Coating Bend Device

1.Description:

With the painted surface facing the outer side of the bend, bend the painted test plate 180° and fold it back to its back with a gradually decreasing radius of curvature. The size of the radius of curvature is determined by the spacers. After the test plates were bent, the cracking of the coating on each sample plate was inspected through a magnifying glass, and the peeling of the coating was observed through the tape pull-off test. The T-bend rating is used to represent the minimum diameter at which the test plate can be bent without cracking or peeling of the coating film, that is, if it does not pass and does not occur again. Or, visual inspection can be carried out through a magnifying glass to determine whether the coating film shows any form of peeling.

The BGD 568-T bending machine complies with the requirements of the folding method (repeated folding of the test plate itself) in GB/T 30791 (Geda is the main drafting unit of this standard) and ISO 17132 "T-Bending Test for Paints and varnishes" standard. It features a compact structure, simple appearance and convenient operation. It is an ideal equipment for determining the bending resistance performance of color steel plates and aluminum plates.
