WIRING INCORPORATED RESIN PIPE AND METHOD OF MANUFACTURING THE SAME
A wiring incorporated resin pipe includes a tubular shaped sheet formed in an approximately tubular shape at an interval so that a slit is formed between both ends in a transverse direction, a wiring unit arranged in the tubular shaped sheet along a longitudinal direction of the slit in an inner side of the slit and a resin material filled in a gap formed by matching surfaces of the slit of the tubular shaped sheet and the wiring unit to thereby seal the matching surfaces of the slit of the tubular shape sheet, in which conductive wires for wiring are laid inside the wiring unit in the longitudinal direction.
FLEXIBLE HOSE MATERIAL AND A WATER PIPE MADE OF THE FLEXIBLE HOSE MATERIAL
The present disclosure discloses a flexible hose material and a water pipe made of the flexible hose material. Raw material components of the flexible hose material includes following ingredients in weight parts: thermoplastic rubber 80 parts to 100 parts, polypropylene 20 parts to 40 parts, wear resistant fillers 30 parts to 40 parts, anti-aging agent 1 part to 3 parts, dispersing agent 1 part to 3 parts and coupling agent 1 part to 3 parts. The flexible hose material of the present disclosure has good wear resistance and anti-aging performance; the problems of complex structure and high production cost are solved; and has important disclosure value. The water pipe made of the flexible hose material has features of a transverse expansion and longitudinal expansion, its expansion coefficient reaches more than 2.5 times; a number of charging and discharging reaches more than 1000 times, and has a long service life.
