| titleOfInvention | Method of coating collecting piping system with post-shrinkable polyurethane foam |
| abstract | (57) [Summary] [Problem] To cover a branched copper pipe system with a large dimensional tolerance, which is complicatedly bent and assembled to reduce the exclusive volume, when covering soundproofing and vibration-proof materials, The increase is minimized, and the coating covers not only the outer surface of the collective piping system but also the inner copper tube surface, and does not cause poor coating in which the copper tube is partially exposed on the surface. SOLUTION: A liquid reaction foamed polyurethane having a large post-shrinkage after molding and a collecting copper tube system are placed in a mold having a smooth inner surface and an inner volume sufficiently larger than the dimensional tolerance in addition to the exclusive volume of the collecting copper tube system. Molded integrally. After molding, the foamed polyurethane greatly shrinks, and a final molded product with a small increase in the occupied volume in which the coated copper tube is raised can be obtained. When a metal powder having a high specific gravity is contained in the foamed polyurethane, the specific gravity once reduced by foaming is increased again by post-shrinkage, so that the improvement in the soundproofing and vibrationproofing effects based on the increase in mass is maintained. |
