Test Background
Asphalt waterproofing membrane is a rollable sheet-like waterproofing material made by dipping asphalt on a base (such as base paper, fiber fabric) and then spreading powdery or sheet isolation materials on the surface. Asphalt waterproofing membrane is a waterproof membrane type product that has a very ideal effect among the entire waterproofing materials and is particularly widely used.
The asphalt waterproofing membrane tear test can determine the tearing performance of the asphalt waterproofing membrane. Zhongke Testing Reliability Experiment Center has the capability of reliability testing of various construction waterproofing membranes and provides professional tear test services for asphalt waterproofing membranes.
Scope of tests
According to different manufacturing methods, it is divided into two types: impregnated membrane (with tires) and rolled membrane (without tires). The former is made by impregnating and coating asphalt with raw paper or glass cloth, fabric and other tire materials, and then sprinkling spreading materials (talcum powder, fine sand, mica powder, etc.) on the surface; the latter is made by mixing asbestos, rubber powder, etc. into asphalt and rolling it.
Test method
Measure the force required by piercing the specimen with a nail rod, and tear it with a force perpendicular to the nail rod.
