according to the characteristics of polyethylene polypropylene, it should be located in the scope of application of cement products maintenance aids, moisture-proof, simple roofing:
must pay attention to:
first, polyethylene polypropylene for the facade, if the surface also paste inorganic tile. must take measures to prevent the front brick off.
1, moisture-proof double-layer just ... polyethylene polypropylene waterproofing membrane for the surface-enhanced structure, the linear low-density polyethylene resin added anti-aging agent, stabilizer, adhesion promoter and high-strength polypropylene filament non-woven, using hot melt pressure composite technology made of composite waterproofing membrane. in recent years, the waterproofing industry evaluation of polyethylene polypropylene waterproofing membrane derogatory praise their words, the manufacturers believe that the material can be applied to any building where the need for waterproofing engineering site, but to promote this concept has been the design department, strong resistance to the construction sector, the author combined personal practice, talk about the scope of the material.
2, polyethylene polypropylene waterproofing membrane scope of application as the polyethylene film surface after polypropylene non-woven fabric, so that the membrane and cement-based materials have good binding force, so the material should be used in conjunction with the rigid waterproof layer. according to the characteristics of polyethylene polypropylene, it should be located in the scope of application of cement products maintenance auxiliary products, moisture-proof, simple roof waterproof. discussion on the application of polyethylene polypropylene waterproofing membrane
3 maintenance of cement products auxiliary goods wet environment generally use waterproof concrete, waterproof mortar, polymer cement waterproof construction, rigid waterproof layer construction is completed immediately bonded a layer of polyethylene polypropylene waterproofing membrane can effectively prevent the rigid waterproof layer in the evaporation of water to prevent the formation of seepage capillary channel to ensure the conservation of rigid waterproofing effect, while polyethylene polypropylene waterproofing membrane also play a moisture-proof and simple waterproof function.
second, there are other surface waterproof polyethylene layer, you must consider the waterproof material between the material impact and construction.
1: moisture-proof double rigid waterproof layer in the middle, bonding a polyethylene polypropylene, not only can prevent rigid waterproof layer unicom capillary channel, but also can play a damp-proof effect. for example: a basement floor leakage occurs, the use of polymer cement waterproof coating on the ground, when scraping the polymer cement, the surface immediately bonded a polyethylene polypropylene waterproofing membrane, the top of the membrane with cement mortar paving the floor brick, basement not only does not leak, but not wet.
2: simple waterproof roof waterproofing shorter life expectancy of simple buildings, you can use polyethylene polypropylene as the main roofing materials. water-resistant requirements of 1 year, polyethylene surface without the use of inorganic protective layer; waterproof life requirements of 2 years, you must use inorganic protective layer.
