DRAIN PIPE AND MANUFACTURING METHOD OF DRAIN PIPE
PROBLEM TO BE SOLVED: To provide a drain pipe with good drainage and a manufacturing method of drain pipe.SOLUTION: A drain pipe 1 has a pipe body 10. The pipe body 10 includes a contact angle adjustment area 12 having a film layer 2, which is formed on an inner face 11 thereof. The contact angle adjustment area 12 has an inclination at a contact angle in which a contact angle of water with respect to the inner face 11 stepwise or continuously getting larger or smaller along an axial direction of the pipe body 10. In a manufacturing method of the drain pipe 1, the film layer 2 is applied over the inner face 11 of the pipe body 10 by means of an ink jet printer.SELECTED DRAWING: Figure 1
【課題】排水性が良好な排水管および排水管の製造方法を提供する。【解決手段】排水管１は、管本体１０を有する。管本体１０の内面１１に、塗膜層２を有する接触角調節領域１２が設けられている。接触角調節領域１２が、管本体１０の軸方向に沿って、水の内面１１に対する接触角が段階的または連続的に大きくまたは小さくなる接触角勾配を有する。排水管１の製造方法において、塗膜層２が、インクジェットプリンタにより管本体１０の内面１１に塗布される。【選択図】図１
