As an important part of roof construction, waterproofing will become the top priority affecting the service life of the entire photovoltaic system. Roof waterproofing with excellent durability and reliability is the basis and prerequisite for the continuous operation of photovoltaic roofs.
Under normal circumstances, the maintenance of steel structure metal roofs is generally due to the deterioration of building quality caused by water leakage or corrosion. Traditional steel structure metal roofs generally require major repairs or replacement of roofing materials after 10 to 15 years of use.
The design life of the photovoltaic roof system is more than 25 years, and the traditional roof waterproof materials are far from meeting the design life of the photovoltaic roof of more than 25 years. The use of traditional roof waterproofing will lead to a substantial increase in the renovation cost of the photovoltaic roof in the later period. Elastomer (SBS) modified asphalt waterproofing membrane has become the main waterproof material in construction engineering waterproofing, and SBS as the main modified asphalt material has become a research hotspot.
Elastomer (SBS) modified asphalt waterproofing membrane is coated with styrene-butadiene-styrene (SBS) rubber modified asphalt, with glass fiber felt, polyester felt, glass fiber reinforced polyester felt as the tire Base, a waterproof material with excellent performance made of insulating materials on both sides, has the advantages of heat resistance, cold resistance, corrosion resistance, aging resistance, good thermoplasticity, high tensile strength, high elongation, and strong tear resistance. .
Industrial and civil buildings such as roofs, basements, walls, toilets, pools, canals, subways, caverns, highways, bridges and airport runways and other waterproof protection projects, metal containers and pipelines are used for anti-corrosion protection. It is a widely used, Waterproof material with excellent performance, which can be used as a single layer or multiple layers; it can be hot-melt or cold-bonded.
