Advantages and disadvantages of pe self-adhesive waterproof membrane
Advantages and disadvantages of PE self-adhesive waterproofing membrane Polyethylene polypropylene composite waterproofing membrane uses polyethylene resin as the main waterproof layer, double-surface composite polypropylene filament non-woven fabric as a reinforcement layer, and a hot melt direct pressure process for one-time composite molding (low grade) The product uses a secondary compound molding process). The main waterproof layer polyethylene film is made of linear low-scale polyethylene (LLDPE) resin with good puncture resistance. At the same time, auxiliary materials are added to improve the flexibility and adhesion of the main waterproof layer of the coil. Carbon black and additives are added. Improve the performance of the main waterproof layer of the coil. The advantages and disadvantages of pe self-adhesive waterproof membrane-Shandong Pengsheng Waterproof has the national construction professional waterproof secondary construction qualification and has passed ISO9001:2015 quality management system, ISO14001:2015 environmental management system double certification and HOSAS 18001:2007 occupational health and safety management system Certified!1. The lap joint adopts hot welding construction, which can form a high-strength reliable sealed waterproof layer.
2. A layer of polyester fiber fabric is sandwiched between the reinforced TPO waterproof coiled material, which provides high tensile strength, high tear strength, fatigue resistance and puncture resistance of the coiled material, and is more suitable for mechanically fixed roofing systems.
3. The fabric on the lower surface of the backing type TPO waterproof coiled material makes the coiled material easier to bond with the base layer.
4. Homogeneous TPO waterproof coiled material has good plasticity and can be processed into various shapes after being heated to adapt to the practice of complex nodes. The advantages and disadvantages of pe self-adhesive waterproof membrane-customers who choose "Pengsheng" waterproof membrane are installed in this way 1) The base layer needs to be solid, clean, dry and flat. 2) During construction, you can directly apply the base treatment agent on the dry base, and the matching base treatment agent. The thickness of the base treatment agent should be uniform, no leakage, no accumulation, and it should be air-tight until it is not sticky. . 3) Flatten the waterproof membrane, peel off the isolation film on the lower surface of the waterproof membrane, use a pressure roller or a scraper to press from the middle of the membrane to both sides, discharge the air, and stick it firmly. 4) The two adjacent webs are lapped using the "self-adhesive self-adhesive" lap method. During construction, the reserved isolation film of the lap self-adhesive edge is torn off and directly pasted. 5) After the roll material has been laid, the exposed lap joints of the roll material, the ends of the roll material waterproof layer, pipes, special-shaped parts and other weak parts can be sealed with special sealing paste or strengthened by the hot-melt edge-sealing method.
What if there is a leak in the kitchen or bathroom? Leakage between the kitchen and the factory is a common problem in construction projects, especially residential projects. Because kitchens and toilets use water for a long time, and the space is small, there are many pipes, and the construction is difficult. The main reason for leakage: the construction operation is not standardized and not serious; the second is the quality of the material. The ground is leaking, the wall is out of alkali, and the water is leaking. Some serious wall decoration layers fall off and the wall is embrittled. The reason is that the construction of the ground and wall waterproof layer fails, and the height of the wall to the waterproof layer is not enough. Ground waterproof layer. The kitchen and bathroom are small, with many pipes and equipment. It is not suitable to use coiled material for waterproofing, but Xu membrane waterproofing should be used. Leakage at the junction of the drainage pipe and the ground. The drainage pipe is close to the corner of the wall, with a small spacing and inconvenient operation. There may be problems of vibration leakage or improper vibration when pouring around the pipe, causing leakage. The method is: pay attention to compact the alkali vibration around the pipeline. And use mortar to compact and polish, 10mm above the ground to avoid water accumulation. When using PVC pipes, the outlet wall is smooth and not easy to bond. More serious construction is required in accordance with relevant regulations and regulations.
