Title: Centrifugal molding of resin tube having corrosion-resistant outer layer
Inventor: YAMAMOTO MASAHIKO
IPC: B29C39/00
Filed: 1982-08-03
Abstract: PURPOSE:To form a resin tube with a corrosion-resistant outer layer, having uniform thickness, in a short time by a method in which a corrosion-resistant resin liquid is cast into a cylindrical mold when the rotation of the mold is stopped, and the rotation and stoppage of the mold are repeated in such a way as to form a corrosion-resistant resin layer and a resin layer inside of the corrosion-resistant resin layer centrifugally, followed by continuous rotation of the mold. CONSTITUTION:When the rotation of a cylindrical mold 1 is stopped and a corrosion-resistant resin liquid 6 is cast into the mold 1, the liquid 6 is stagnated in the lower part, and the liquid 6 is lifted up by turning the mold 1. In this case, the liquid 6 is bonded with the inner surface of the mold 1, and when the rotation of the mold 1 is stopped at a time when thick portion of the liquid 6 reaches the upper level, the liquid 6 in the upper level flows down along the inner surface and a layer is formed over the whole area although the thickness is uneven. By repeating the rotation and stoppage of the molds several times, a nearly uniform corrosion-resistant resin layer 6 is formed on the inner surface. Afterwards, the mold 1 is continuously turned to equalize the thickness and also harden the resin layer in such a way as to form the corrosion- resistant resin layer 7 on the inner surface of the mold 1 centrifugally. A fiber 8 is then wound on the inside of the layer 7, and resin is impregnated into the fiber 8 and molded into a resin layer 9 centrifugally. A resin tube 10 with corrosion-resistant outer layer having uniform thickness can thus be molded.
