Product Information:
?
Polyvinyl chloride (PVC) waterproof sheet is a high quality polymer waterproof sheet with excellent performance. Plasticizer, anti-ultraviolet agent, anti-aging agent, stabilizer and other processing additives are added to PVC resin, and the polymer waterproof sheet is produced by extrusion method. The product has high tensile strength, high elongation, good stability, small shrinkage, low temperature flexibility, good anti-aging performance, strong root penetration resistance, long service life, and is recommended by the Ministry of Construction, especially its wide width of 2.05 meters, thus subtracting many joint hidden dangers for the waterproof layer. The thermoplasticity of PVC endows the coil with the performance of hot air welding and alert fixing, which completely solves the problem of penetration and leakage caused by poor glue performance in the construction industry. Product width 1.05 meters, 2.05 meters, 2.1 meters, thickness 0.8, 1.0, 12,1.5, 2.0mm, standard length 2.0m(special specifications can be customized), product quality is reliable, convenient construction. Due to the product formula used in this product, the product life is far beyond the general waterproof material, the whole waterproof system has a long life, more than 30 years of roof, underground more than 50 years, and has been widely used in construction and civil engineering.

Key points of construction
?
1. Long service life, aging resistance, roofing material can be used for more than 30 years, underground up to 50 years.
?
2. High tensile strength, high elongation, small size change in heat treatment.
?
3. Good low temperature flexibility, good adaptability to environmental temperature changes.
?
4. Good root penetration resistance, can be made into planting roof.
?
5. Good perforation resistance and impact resistance.
?
6. Convenient construction, less wide width lap, customer welding, firm and reliable and pollution-free.
?
7. Strong chemical resistance, suitable for special occasions.
?
8. With good plasticity, corner details processing is convenient and fast.
?
9. Easy maintenance and low cost.
?
10. The light color of the surface reflects ultraviolet radiation, and the west of the surface of the coil has less heat and low temperature.
?
11. Coil has good water vapor diffusion, condensate is easy to release, and moisture and moisture left at the base are easy to discharge.

Application field
?
Polyvinyl chloride (PVC) waterproof coil due to the use of the product formula, the life of the initial product is far beyond the general waterproof material, and the excellent performance of the coil is widely used in various fields of waterproof.
?
(1) Suitable for roofing waterproofing of industrial and civil buildings, including planting roofing, flat roofing and slope roofing.
?
(2) Building underground waterproof: including reservoirs, DAMS, pools, canals and basement parts waterproof.
?
(3) Tunnels, grain depots, civil air defense projects, landfill, waterproofing of artificial lakes, etc.

Full viscous system
?
Generally used for roofing, basement side wall. The composite non-woven PVC is bonded to the base (concrete surface, metal surface, wood surface) with special adhesive, and the bond is firm. The non-woven fabric under PVC can play the role of isolation, protection and buffering. Base requirements: moisture content ≤8%, and smooth, dense, no peeling, etc., the construction is affected by the weather.

?
?
Mechanical fixing system
?
Generally used in roofing engineering, the base is pulled out test, according to the pull out value, wind load and dynamic wind load simulation test value and empirical formula, calculate the distance and number of fixed parts, in order to meet the requirements of wind buoyance. The fixed parts are self-tapping drill self-tapping screws and special metal gaskets. Construction is less affected by weather and temperature.

?
?
PVC gasket fixing system
?
Generally used in basement side walls, railway and highway tunnels, side walls and vaults. Base smoothness requirements: 1/8-1/6(high loss ratio). This method is not affected by the temperature and humidity of the base, and can be constructed even if there is water seepage on the surface of the base.
?
?
?
Empty berth system
?
Generally used for underground, roof, floor, roof garden and pedestrian roof. No adhesives or fixings. According to the needs of users, a layer of non-woven fabric is added to the waterproof layer as a protective layer.
