Urban air pollution, industrial exhaust emissions, and other causes lead to the formation of acid rain, it can be divided into "wet settlement" and "dry settlement", the former refers to all air pollutants or particulate pollutants that fall to the ground with rain, snow, fog or hail. The latter refers to the acidity of dust falling from the air on rainfall days.
Whether it is "wet settlement" or "dry settlement", the acid material has corrosive effects on all objects, and the metal properties are particularly serious. Against these acidic substances, however, Rufu PVC tiles for roof is the "umbrella" to protect human health and property safety, the safety factor is not high? Roofing materials play a decisive role, like colored steel tiles, which are not suitable, especially in areas with severe acid rain.
After authoritative experiments confirmed: PVC roof tiles sheet soaked in salt, alkali, and below 60% of various acids for 24 hours without chemical reaction, can effectively prevent acid.PVC roof sheets has a large span of up to 40-50 meters long and are suitable for steel structure industrial plants.
Can save the cost of steel structure, and can effectively protect the steel structure from acid erosion. In addition to effective acid prevention, PVC roof sheet also has heat insulation, water resistance, sound insulation, insulation, impact resistance, load resistance, and other advantages, and can be widely used in factories, market, shed, warehouse, and other fields.
