Difference between polymer modified asphalt waterproofing membrane and pressure-sensitive reactive waterproofing membrane

Advantages of pressure-sensitive reactive materials

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. It is an ultra-high performance modified asphalt waterproofing membrane made of specially processed long fiber polyester non-woven fabric as tire base, polymer modified asphalt made of special formula as impregnation and coating material, and fine sand isolation materials on both sides.

Product characteristics

1, excellent water resistance: no water absorption, no performance degradation under long-term corrosion, no permeability under the action of 0.4MPa pressure water;

2. High tensile strength and elongation: the base layer has strong resistance to shrinkage, deformation and cracking; When cracks appear in concrete bridge deck under stress, it has flexibility;

3. Excellent high and low temperature resistance: the standard product does not break when bent at -35℃, and does not deform at 120℃ within the normal use range of -20℃-60℃;

4. Ultra-high mechanical properties and large thickness give the coil excellent fatigue resistance and construction damage resistance. Under the load, the coil is repeatedly acted at the frequency of 50HZ for 20 million times, and there is no crack in the coil;

5. Excellent dimensional stability: when heated at 80℃ 168h, the dimensional change is within 0.5;

6, aging resistance, salt resistance, acid and alkali resistance, mildew resistance, durability and long service life;

7. Excellent bonding performance: hot melt construction, firm and lasting bonding with the base, under the action of 2 million times of repeated compression and tension, the bonding layer does not crack, which can effectively resist the driving load.
