pe pp waterproof membrane for shower walls The manufacturer tells you that the national standard GB18242-2008 "Elastomer Modified Asphalt Waterproof Membrane" or GB18243-2008 "Plastomer Modified Asphalt Waterproof Membrane" 3.4.3 clearly requires that "the upper surface should be used for exposed use."

pe pp waterproof membrane for shower walls The manufacturer tells you that the national standard GB18242-2008 "Elastomer Modified Asphalt Waterproof Membrane" or GB18243-2008 "Plastomer Modified Asphalt Waterproof Membrane" 3.4.3 clearly requires that "the upper surface should be used for exposed use." The isolation material is a waterproof membrane made of opaque mineral pellets.” While ordinary PE membrane waterproof membranes cannot be used on exposed roofs, they must be protected in time. Why is that?

The manufacturer of pe pp waterproof membrane for shower walls tells you that after the PE membrane surface modified asphalt waterproofing membrane is constructed, due to the influence of the sun, rain, etc., the surface PE membrane will crack, weather, wind and peel, and black asphalt The surface continues to absorb heat, and sticky feet can also occur in high-temperature climates.
So, how does the aging of waterproof membrane material happen and change?
First of all, the PE film is exposed to the sun, and the photon catalyzes the aging of the PE structure, which leads to the weathering of the film. pe pp waterproof membrane for shower walls The manufacturer tells you that the PE film on the upper and lower surfaces of the asphalt membrane is a polyethylene film. Under the influence of the external environment (such as solvents, oxygen, etc.), there is residual stress during the processing of PE materials, which makes The phenomenon that the material cracks when it is far below the yield stress value is called environmental stress cracking. It is a unique phenomenon of PE film.
Secondly, the exposure of modified asphalt accelerates the natural aging process. The manufacturer of pe pp waterproof membrane for shower walls tells you that a series of complex physical and chemical reactions have taken place, including oxidation, light component volatilization and absorption, polymerization and agglomeration, and pyrolysis of modifiers. According to the different aging conditions, the aging form and aging degree of modified asphalt are also different.
Third, direct pouring of the concrete protective layer is the most effective measure to avoid accelerated aging of waterproof materials;
Fourth, as a product that can reflect ultraviolet radiation, the metal surface coil has the effect of heat insulation and anti-aging. In addition to solving the problem of excessive weathering of the PE film, it can also protect the modified asphalt on the surface of the coil for a long time, reduce the aging speed, and extend Exposed service life effect.
Seeing this, it is not difficult for everyone to find that there is actually a reason why the modified bitumen waterproofing membrane of the pe film can not be used on the exposed roof. pe pp waterproof membrane for shower walls The manufacturer tells you that if it is used forcibly, it may cause water leakage and cause many unnecessary troubles for everyone. So when you choose waterproof membranes in the future, you must also follow your own actual situation.
