Polyester fiber reinforced polyvinyl chloride (PVC) waterproofing membrane is a kind of thermoplastic PVC membrane, which is a polymer membrane compounded by double-sided PVC plastic layers and intermediate polyester reinforcement through a special extrusion coating process. The combination of PVC plastic layer with advanced formula and polyester fiber fabric with net structure makes the coil have excellent dimensional stability and low thermal expansion coefficient. Improve the long-term performance of coils directly exposed to the natural environment. Product specification and model: width: 2-2. 1m, thickness: 1.2mm-2.0mm, length: 20m or more. Construction method: hot air welding to ensure the weld effect.
Features:
1, PVC waterproofing membrane has high tensile strength, good elongation and small thermal dimensional change rate.
2. It has good weldability, and the weld seam is integrated with the parent metal after hot air welding.
3. It has good water vapor diffusivity, and the condensed water is easy to be discharged, and the residual moisture and moisture at the grass-roots level are easy to be discharged.
4. Aging resistance, ultraviolet radiation resistance, chemical corrosion resistance and root penetration resistance.
5. It has good flexibility at low temperature (-20℃).
6. Long service life (25 years on the roof and more than 50 years underground) and no environmental pollution.
7. The colored surface reflects ultraviolet rays, so the surface of PVC waterproofing membrane absorbs less heat and the temperature is low.
8. Excellent flexibility and ductility, high tensile strength, excellent dimensional stability, high mechanical strength, corrosion resistance, root penetration resistance, weather resistance, ultraviolet resistance and hail resistance.
Precautions:
1 When laying PVC waterproofing membrane, attention should be paid to the construction environment temperature, and the temperature of the membrane should be above -5℃. The temperature of the coil can only be above 5℃ when the full adhesion method is adopted.
2, the shop is stuck PVC waterproof coiled material, special parts should be additional layer.
3, pay attention to the construction protection, daily coil should be temporarily fixed before the end of the construction, so as not to be blown by the wind.
4, waterproof layer construction must be carried out after the last process, shall not be cross construction. If it is necessary to install equipment on the roof with waterproofing membrane, additional layer treatment should be done on the basis of the equipment. If you need to build a high-rise residence on the waterproof layer, you must pass the acceptance of the waterproof layer.
Construction sequence:
The inverted construction method should be adopted, that is, the waterproof layer is below and the insulation layer is above.
