Recubrimiento en caucho termoencogible para mitigar patologías en tubería hidráulica en PVC expuestas

Abstract

This research focuses on the pathologies of PVC hydraulic pipes that are exposed on roofs of residential homes in the city of Bogotá, presenting expansion produced by sunlight and contraction due to a reduction in temperature, thus generating crystallization, cracks and fissures. in the hydraulic pipeline. In this way, construction pathologies such as water leaks, plaque humidity and structural. weakening can be caused. It is evident that these problems are recurrent in residential homes, specifically in two-story homes, which have water reserve tanks and exposed pipes on roofs, due to these drawbacks, various products have been generated for the protection of hydraulic pipes, such as are the ½ inch PAVCO flexible conduit pipes and the HDPE + UV jacket coating that retards the freezing of water in PVC pipes, however they do not prevent it effectively. Now, taking into account that in the market it is not possible to find an efficient product to meet this need, we seek to optimize a shrink-type heat shrinkable rubber coating for new PVC hydraulic pipes to improve the pipe's response to these pathologies, thus giving a possible solution to the aforementioned drawbacks.
