| titleOfInvention | Production of artificial pumice stone |
| abstract | PURPOSE: To enhance stability of quality by overlapping an intermediate felt body wherein a through-hole is bored to the inside on a felt body made of water absorptive fiber and forming a hole to the inside and incorporating a dead weight into the through-hole, laminating and bonding these felt bodies and thereafter coating the whole circumference with ceramic. n CONSTITUTION: A polygonal felt body 1 having prescribed wall thickness (h) is manufactured with water absorptive fiber of synthetic fiber such as PP and polyester. An intermediate felt 2 wherein a comparatively large through-hole 3 is bored in the center of the inside is overlapped so that this intermediate felt 2 is pinched between the upper and lower felt bodies 1, 1. A dead weight 4 which is made of a stone and rustless metal, etc., and has prescribed weight is incorporated into the through-hole 3. The intermediate felt and the felt bodies are pressed and bonded. The prescribed amount of coating 5 is applied to the whole surface of the laminated and bonded outer circumference. Thus, artificial pumice stone having a porous outer surface is obtained. n COPYRIGHT: (C)1991,JPO&Japio |
