Test Background
Asphalt waterproofing membrane is the traditional and most widely used waterproofing membrane, commonly known as asphalt linoleum, and is mainly used in roof waterproofing projects. Asphalt linoleum mainly includes petroleum asphalt linoleum, petroleum asphalt linoleum paper, asphalt glass cloth linoleum, asphalt fiberglass linoleum, asphalt recycled rubber linoleum, coal tar asphalt linoleum and special asphalt linoleum. The peeling characteristics between lap widths of asphalt-based coils vary with materials, lap methods (flame or thermal welding, thermal bonding or asphalt, cold adhesive, etc.), lap size, and operating techniques.
The seam peeling test of asphalt waterproofing membranes can determine the joint peeling performance of asphalt waterproofing membranes. Zhongke Testing Reliability Experiment Center has the capability of reliability testing of various construction waterproofing membranes, and provides professional joint peeling 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
The joints of the specimen are stretched at a constant speed until the specimen separates, and the tensile force throughout the test is continuously recorded.
