Constant load corrosion bending testing machine

1. Equipment name: Constant load corrosion bending testing machine

2. Equipment introduction: The constant load corrosion bending testing machine is used to conduct corrosion bending tests on FRP materials in corrosive environments.The host structure is in the form of four columns, and the loading mode uses a servo motor loading unit for loading.This test system consists of a bending loading system, a corrosive environment container, a heating system, a test fixture, a measurement and control system, a test software, a computer, and a control cabinet.
