Description
Technical Field
[0001] The present application relates to the technical field of asphalt coil welding performance detection, and in particular to a standard equipment for welding the overlapped edges of standard asphalt coils. Background Art
[0002] Asphalt waterproofing membrane is a commonly used waterproofing material in construction projects. During the laying process of asphalt membrane, it is necessary to weld the asphalt membrane, and the welding performance of the waterproofing membrane is very important for the effectiveness and durability of waterproofing. The peel adhesion test is used in the welding performance test of waterproofing membrane. The test involves overlapping and welding the asphalt waterproofing membranes, and then applying controlled force to them to determine the degree of adhesion on the surface of the asphalt waterproofing membrane, so as to obtain the bonding strength of the waterproofing membrane.
[0003] When testing the welding performance of asphalt waterproofing membranes, the quality of asphalt waterproofing membrane welding has a great influence on the subsequent peeling adhesion test. In order to ensure that the material melts evenly and quickly and forms a smooth and consistent weld, the temperature, pressure, and welding speed all need to be controlled during the welding process of the asphalt waterproofing membrane. If the welding temperature is too low, the welding performance will be poor. If the temperature is too high, the material will be damaged. If the welding speed is too fast, the material will not be fully fused. If the speed is too slow, the material will be damaged. The welding pressure needs to ensure that the material can be firmly welded. If it is too large, it will also damage the material. Utility Model Content
