BAIJIAN - Third party testing organization
The main types of testing for polymer waterproof sheets include homogeneous sheets、 composite sheets、 irregular sheets、 self-adhesive sheets、 point adhesive sheets、 etc. These sheets are generally used for waterproofing、 anti-seepage、 moisture-proof、 pollution prevention、 air isolation、 drainage、 and other work. These sheets are divided into resin sheets、 vulcanized rubber sheets、 and non vulcanized rubber sheets based on different raw materials
Testing items for polymer waterproof sheets 1. Specification and size testing items: width measurement、 thickness measurement、 and length measurement; 2. Appearance quality inspection items: surface defects of the sheet material (impurities、 mechanical damage、 creases、 adhesives、 depth of dents、 depth of bubbles、 etc.); 3. Physical performance testing items: (1) Physical properties of homogeneous sheets: tensile strength、 elongation at break、 tear strength、 impermeability、 low-temperature bending、 heating expansion、 hot air aging、 alkali resistance、 ozone aging、 artificial climate aging、 bonding and peeling strength; (2) Physical properties of composite sheets: tensile strength、 elongation at break、 tear strength、 impermeability、 low-temperature bending、 heating expansion、 hot air aging、 alkali resistance、 ozone aging、 artificial climate aging、 bonding and peeling strength、 composite strength; (3) Physical properties of self-adhesive sheet material: If the main material of the self-adhesive sheet is of the above two types、 it shall be tested according to its testing items. Its low-temperature bending performance、 adhesion performance、 and peel strength need to be tested separately; (4) Physical properties of profiled sheets: tensile strength、 elongation at break、 compressive performance、 drainage cross-sectional area、 hot air aging、 and alkali resistance; (5) Physical properties of point adhesive sheets: In addition to homogeneous sheet samples、 their room temperature tensile strength、 room temperature elongation at break、 and peel strength need to be tested separately
