APF-3000 strong cross film self-adhesive waterproofing membrane is a kind of high strength thin cross laminated high density polyethylene (HDPE).
A high-performance cold-applied self-adhesive composite membrane waterproof coiled material is made of coiled material and high-quality polymer self-adhesive rubber asphalt through a special process, and has the following characteristics
Excellent dimensional stability, thermal stability, ultraviolet resistance and two-way tear resistance.
main feature
● Strong double-layer film has higher tear strength and dimensional stability, and its waterproof performance is better than that of ordinary film.
● The vertical and horizontal network structure design effectively solves the phenomenon that HDPE polymer sheets without tire base are prone to wrinkling and bulging after construction.
● After technical treatment, the mask has the performance of resisting ultraviolet radiation. Even if it is exposed for a long time after construction, it will not affect the appearance quality of the product, and the time can reach about 6 months.
Excellent high and low temperature resistance, can adapt to the climate change in hot and cold areas. Excellent ductility and tensile properties, adapt to the deformation of structural foundation.
● The high-quality self-adhesive layer has excellent self-healing performance and local self-locking water performance, which greatly reduces the leakage probability.
It has unique puncture resistance, self-healing and continuous tear resistance, and the nail shaft is excellent in water tightness.
● Innovative construction methods can be adopted, such as dry paving, wet paving, empty paving and pre-paving anti-sticking construction, which reduces labor intensity and is more suitable for grassroots requirements.
● The width is 1m-2m to choose from, which reduces the overlap and makes the construction faster, especially suitable for large-scale construction.
● Safety and environmental protection. The construction of APF-3000 self-adhesive coiled material is cold construction, which is environmentally friendly and eliminates the potential safety hazard in the construction site.
application area
Waterproofing of basement, subway, tunnel, pool, roof, roof planting of underground garage, roof garden and other projects.
Polymer modified asphalt waterproofing membrane is made of modified asphalt as coating material. Ordinary petroleum asphalt materials are easy to harden and become brittle at low temperature, with cracks and strong temperature sensitivity. Under the long-term action of solar ultraviolet rays, they soften at high temperature in summer, resulting in pyrolysis and flow. Repeated thermal expansion and cold contraction will cause the change of internal stress of asphalt. Under the combined action of oxygen and ozone, the chemical composition of asphalt is constantly changing. First, the oil volatilizes, the asphalt content decreases, the plasticity decreases, the brittleness increases, the cohesive force decreases, and cracks and aging appear. For these reasons, the traditional petroleum asphalt waterproof materials can no longer meet the needs of building waterproof and durable life. Since the mid-1970s, China has been developing synthetic polymer modified asphalt. Adding a certain amount of polymer modifier to asphalt can improve the inherent low-temperature brittleness and high-temperature fluidity of asphalt. The modified asphalt not only has good high and low temperature performance, but also has good elasticity, plasticity, hydrophobicity and cohesiveness. Compared with asphalt waterproofing membrane, the tensile strength, heat resistance and low temperature flexibility of polymer modified asphalt waterproofing membrane have been improved to some extent, and it has better impermeability and corrosion resistance.
I recommend you to choose the waterproof products of Oriental Yuhong and the standardized construction team, which is the best waterproof listed enterprise in China.
RWB-80 1 polymer modified asphalt waterproofing membrane for railway bridges and culverts
Yuhong RWB-80 1 Polymer modified asphalt waterproofing membrane for railway bridges and culverts is specially designed for the waterproof layer of railway concrete bridges and culverts.
