PVC waterproofing membrane No. Item Indicator requirements GB/T12952-2013 H L G P GL Resin layer above the middle tire base/mm ≥ - 0.40 Tensile properties Maximum pulling force/(N/cm)≥ - 120 250 - 120 Tensile strength/MPa≥ - - 10.0 - The maximum tensile force is elongation/%≥ - - 15.0 - - Elongation at break (%) ≥ 200 150 - 200 100 Heat treatment dimensional change rate/%≤ 2.0 1.0 0.5 0.1 0.1 low temperature bendability -25℃，No cracks Impermeable 0.3MPa，2h watertight Impact resistance 0.5Kg·m watertight NotesEdit 1. When laying PVC waterproofing membrane, attention should be paid to the temperature of the construction environment, and the temperature of the membrane should be above -5℃. When using the full adhesion method, the temperature of the coil can only be above 5 ℃. 2. When laying PVC waterproofing membrane, special parts should be additional layers. 3. Pay attention to construction protection. Before the end of daily construction, the coil should be temporarily fixed to avoid being blown up by the wind. 4. The construction of the waterproof layer should be carried out after the end of the previous process, and no cross construction is allowed. If the equipment needs to be installed on the roof where the waterproof membrane has been laid, an additional layer should be applied to the basic part of the equipment.
