Determination of cracking resistance and elongation of JINGKELIAN QTZ Conical Mandrel Bending Tester coatings

QTZ

Conical Mandrel Bending Tester

The mechanical tester for measuring varnish and Paints coatings can evaluate the cracking performance and elongation of coatings when they are bent around conical mandrel under standard conditions. It conforms to a variety of international or national standards, such as ISO6860-1984 (E), ASTMD522-60 (1979), BS3900; Part E11:1985, etc.

Overview of QTZ paint film conical bending tester

JinKeLian QTZ paint film conical bending tester is a mechanical tester for measuring varnish and colored paint coatings. It is mainly used for cracking resistance or peeling from metal plates when bending around a conical axis under standard conditions. It can also be used to determine the elongation of coatings. QTZ paint film conical bending tester complies with ISO6860-1984(E), ASTMD522-60(1979), BS3900; PartE11:1985 various international or national standards.

Principle

The QTZ paint film conical bending tester is a purely mechanical design. Its principle is: first insert the test plate between the pull rod and the tapered shaft, then use the splint to clamp the hand-held joystick, and turn the shaft from front to back (to make the test plate Deformation around the cone axis), the peeling performance is determined according to the crack position of the coating on the test plate.
