GB/T 13477.13-2019 Focus on the determination of the adhesion of sealing materials after cold drawing and hot pressing. It specifies the test equipment, such as the device requirements for accurate temperature control and Schgara compressive load. Specify the production of specimens, and bond the sealing material to the substrate. First cold draw the specimen to simulate low temperature stretching, and then hot press to simulate high temperature extrusion. By observing the bonding status of the sealing material and the substrate after the test, the bonding performance is determined. The standard simulates the complex temperature conditions of buildings, providing a basis for evaluating the bonding Reliability of sealing materials in an alternating temperature environment, ensuring the stable operation of sealing projects under various temperature conditions.
