MODERNER WQ-ⅱ Bending Tester

Overview

The WQ-II cylindrical flexure Tester is used for testing the resistance to cracking and peeling from the substrate when the coating of pigments, varnishes and related products is bent around the cylindrical shaft, in accordance with the national standard GB/T 6742-2007 (equivalent to the ISO 1519:2002 standard of the International Organization for Standardization). This instrument can be used for test boards with a thickness of no more than 1mm, as long as the shaft is not deformed, and can also be used for thick soft metals such as aluminum test plates and plastic test plates. For boards with a thickness greater than 0.5 mm, it is recommended to avoid using shafts with a diameter of less than 10 mm for testing.

The bending part is a nylon guide plate, which can be adjusted by rotating the handle with the position of the shaft rod (sleeve). The bent parts can be flipped 180 degrees around the copper sleeve, and the inner hole of the copper sleeve is used to install various specifications of shaft rods. The 20mm, 25mm and 32mm specifications are bushings, which can be sleeved on the 16mm shaft rod when used. To prevent the coating from being scratched during bending, a piece of tissue paper can be inserted between the test plate and the bent part.

Structure and operation (see attached drawing)

The bending part is a nylon contact plate, which can be adjusted by turning the handle in the position of the round shaft (sleeve). The bent parts can be rotated around the copper sleeve, and the middle of the copper sleeve is used to install various specifications of round shafts. The 20mm, 25mm and 32mm specifications are round sleeves, which can be set on the 16mm round shaft when used. To prevent the coating from being scratched during bending, a piece of tissue paper can be inserted between the test plate and the bent part.

Host, 1 piece each of 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 16mm round shaft, 1 piece each of 20mm, 25mm, 32mm round sleeve
