As we all know, exterior water system is the most difficult to solve the problem of aging and Ken color material, a mature formulation technology, superior product performance to maintain stability; through numerous experiments and applications, has mastered the most cutting-edge new materials development of technology; therefore, this product can UV aging resistance, acid corrosion, look as new. Water system does not require special tools to install, no bonding, construction convenient gutter capping production of refined, using reliable way between member intercalation connection to ensure that the system does not leak; drainage is more smooth; the water system also has good flexibility , good low-temperature impact resistance characteristics. 1 Cailv the water system of gutters, downspouts and other outer layer, PE protective film has a dense, can be partially prevented bump, scratch. 2 Cailv when the water system is installed on site, to prevent other types (such as tiles, stone) in the construction process damage installed water pipe, we generally only the first floor of the gutters and downspouts installed (a height of about 3 meters ), one part of the water pipe to be removed after completion of the palm rest angle (that is, after the end of the other types), using a ladder to install. In this case, in order to prevent rainwater from downspouts shed walls pollution when it rains, must first add a bend in the tube mouth, the water diverted from the direction of the wall. 3 surface in a place gutters or downspouts have minor scratches, while Diaoqi phenomenon, we provide the use of special metal refinishing repair. 4 certain serious bump, Make this cut, then re-plug, can be fixed. In summary, this article how effective protection Cailv the water system products, related practitioners to give us a great help, I hope you can further share their experience and knowledge.
