What is tpo polymer waterproofing membrane?
TPO waterproofing membrane, that is, thermoplastic polyolefin waterproofing membrane, is a new type of waterproofing membrane based on thermoplastic polyolefin (TPO) synthetic resin combined with ethylene-propylene rubber and polypropylene, which is made by adding antioxidants, antioxidants and softeners through advanced polymerization technology. It can be made into reinforced waterproof coiled material with polyester fiber grid cloth as the inner reinforcement, belonging to synthetic polymer waterproof coiled material products.
Construction technology of tpo polymer waterproofing membrane
1. Remove sundries and debris from the base surface.
2. Spread a layer of polyethylene film, and the overlapping parts of the polyethylene film are bonded with adhesive strips.
3. Laying extruded foam insulation board and fixing it with special fasteners.
4. Pre-paving TPO waterproofing membrane: paving TPO waterproofing membrane on the insulation layer according to the control position of elastic line, and paving the membrane with the laying direction perpendicular to the corrugated direction of profiled steel plate on the insulation layer according to the contour. Coil should be kept straight and not twisted. The lap width is 120mm, and it shall be cut appropriately.
5. Fixation of 5.TPO waterproofing membrane: Use fasteners and washers to fix the membrane at a distance of 30mm from the edge of the membrane, as shown by the marking line.
6. Coil lap: lap a pair of coils on another coil, so that the fasteners and gaskets are covered under the waterproof layer. When welding each lap seam with a welding machine, it is necessary to carry out inflation detection.
7. Node treatment: Cut off the coil piece suitable for the corresponding node and weld it on the large coil with a hand-held welding gun.
8. Node treatment: Cut off the coil piece suitable for the corresponding node and weld it on the large coil with a hand-held welding gun.
Matters needing attention in the construction of tpo polymer waterproofing membrane
1. Waterproof coiled materials shall be laid by rolls, and the lap width shall not be less than 120mm. Joints should be firmly bonded, and there can be no seams, false adhesion and empty drums.
2. The weld shall be inflated for at least 2 minutes, with the pressure not less than 0. 15Mpa and the pressure drop not more than 20%.
3. Visual inspection and mechanical inspection (i.e., flat screwdriver) are used for weld detection of hand-held welding torch.
Conclusion: Through the above introduction, I believe everyone has a certain understanding of the construction technology of tpo polymer waterproofing membrane and tt European polymer waterproofing membrane. Tpo polymer waterproofing membrane is a very high-quality exterior wall decoration material, which can not only make the exterior wall look more beautiful and elegant, but also effectively prevent the exterior wall from being damp, and has very strong waterproof performance. I hope that through the above introduction, we can help you understand what tpo polymer waterproofing membrane is and its construction technology.
