Pvc waterproofing membrane is Polyvinyl chloride(PVC) waterproofing membrane, and that is based on polyvinyl chloride resin as raw material, blending plasticizer, filler, antioxidant, UV absorber and other additives such as a squeeze and Into a new type of polymer waterproofing membrane.
It has a lot of features, such as: it is a green environmental protection, non-toxic, harmless, non-polluting, with long-term plasticity, recyclable size and color, stable long-term weather resistance, anti-ultraviolet and heat aging resistance, excellent low temperature flexibility, from the fire Self-extinguishing, effective resistance to harmful chemical substances, industrial pollutants erosion, wear resistance, seams formed by hot air welding, solid and reliable, with long-term solderability, construction convenience, according to the base surface, duration selection of different construction techniques , good plasticity, suitable for detailed treatment, easy maintenance and low cost, width of 2 meters, the material construction loss is small, the surface is smooth, easy to stick ash, easy to clean, conducive to water vapor diffusion (closed moisture can be discharged through the coil will lead to blisters), anti-ultraviolet and anti-solar radiation,and to meet the green building LEED certification requirements, that can be directly exposed to use, without protective layer, up to 25 years or more reasonable life
1, paving PVC waterproofing membrane, the construction should pay attention to the ambient temperature, coil temperature of -5 ℃ or more. The use of full thickness of the construction, the coil temperature can only be used in more than 5 ℃.
2, paving PVC waterproofing membrane, the special parts should be additional layer.
3, pay attention to construction protection, the daily construction should be temporary before the end of the coil fixed, so as not to be blowing the wind.
4, the construction of the waterproof layer should be carried out after the end of the process, not cross construction. If you need to install a waterproof roof in the installation of equipment, should be in the equipment at the base of the additional layer of treatment, for high-level cover in the waterproof layer, subject to acceptance of the waterproof layer after passing.
