Test items for polymer waterproof waterstops
1. Dimension measurement: thickness tolerance measurement、 width tolerance measurement
2 Appearance quality evaluation: defects such as center hole deviation、 cracking、 and sponge paper、 surface dents、 bubbles、 impurities、 scars、 etc.
3. Physical performance testing items: hardness、 tensile strength、 elongation at break、 compression deformation、 tear strength、 brittle temperature、 hot air aging performance、 ozone aging performance、 rubber to metal bonding performance、 rubber to cord fabric bonding strength. Usually、 polymer waterproof material waterstops are developed in new products Or testing is required after formal production. Moreover、 according to the regulations in GB "Polymer Waterproof Materials - Part 2: Waterstops"、 waterstop products need to undergo periodic inspections. The ozone aging performance should be tested less once a year、 the brittleness temperature index should be tested less once every six months、 and compression deformation、 hot air aging、 rubber to metal bonding、 rubber to cord fabric bonding strength should be tested again every quarter
