Structure for membrane material Chokawa time prediction method

摘要

PROBLEM TO BE SOLVED: To provide a membrane material in which the deterioration progression of a membrane material can be easily noticed without braking membrane structure and a replacement time of the membrane structure can be properly determined, when the membrane structure such as a middle or large sized tent or a tent warehouse is used outdoors for a long period of time.;SOLUTION: A flexible laminate includes: a base cloth formed of a fabric material; a first thermoplastic resin layer coating at least one face thereof; and a second thermoplastic resin layer coating the first thermoplastic resin layer. Only the first thermoplastic resin layer contains spherical minute beads, and the occupancy of the first thermoplastic resin layer with respect to the mass of the flexible laminate is 20-40 mass%.;COPYRIGHT: (C)2013,JPO&INPIT
