Waterproof roll tensile testing device

Abstract

The invention discloses a waterproof roll tensile testing device which comprises a rack, an upright, a servo motor, a screw, a linear guide rail, a feeding nut, a base, a tensile force sensor, an upper chuck, a lower chuck and a controller. During working, a waterproof material is placed between the upper chuck and the lower chuck to be clamped, the controller controls the servo motor to work, the servo motor drives the feeding nut to upwards move on the linear guide rail through the screw so as to drive the base to slide on a guide rod until the waterproof material is broken, the tensile force sensor detects tension in real time and sends the same to the controller, and the controller displays a calculation result. The waterproof roll tensile testing device is simple in structure, stable in action, free of impact and high in sensitivity, the waterproof material is firm and reliable in mounting, and experiment data are accurate and reliable.

Description

technical field

[0001] The invention relates to a testing device, in particular to a tensile testing device for waterproof coiled materials. Background technique

[0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering basis There is no leakage connection between the building and it is the first barrier for the waterproofing of the whole project, which plays a vital role in the whole project. Therefore, the waterproof membrane needs to bear a certain load, stress or not under certain deformation conditions. The performance of fracture is usually indicated by indicators such as tensile force, tensile strength and elongation at break. In order to obtain specific indicators such as tensile force, tensile strength, and elongation at break, it is necessary to conduct a tensile test on the water r...
