Title (EN) HOSE FOR TRANSPORTATION OF REFRIGERANT
(FR) TUYAU D'ACHEMINEMENT DE FLUIDE FRIGORIGÈNE
(JA) 冷媒輸送用ホース
Abstract: front page image
(EN)The purpose is to provide a hose for transporting a refrigerant, which has excellent acid resistance, does not undergo cracking, and has excellent interlayer adhesion properties. The hose for transporting a refrigerant comprises a tubular inner layer (1) that contacts with a fluorine-containing refrigerant, an intermediate layer (2) which is formed on the outer peripheral surface of the inner layer (1), and at least one rubber layer (3, 5) which is formed on the outer periphery of the intermediate layer (2), wherein the inner layer (1) comprises an inner layer material mainly composed of a polypropylene modified with maleic anhydride and the intermediate layer (2) comprises an intermediate layer material mainly composed of a polyamide resin.
(FR)Cette invention concerne un tuyau destiné à acheminer un fluide frigorigène. Ledit tuyau présente une excellente résistance aux acides, il ne subit pas de fissuration, et il présente d'excellentes propriétés d'adhésion entre couches. Le tuyau d'acheminement de fluide frigorigène comprend une couche interne tubulaire (1) qui entre en contact avec un fluide frigorigène contenant du fluor, une couche intermédiaire (2) formée sur la surface périphérique extérieure de la couche interne (1), et au moins une couche de caoutchouc (3, 5) formée sur la périphérie extérieure de la couche intermédiaire (2). Ladite couche interne (1) comprend un matériau de couche interne principalement constitué d'un polypropylène modifié par anhydride maléique, et la couche intermédiaire (2) comprend un matériau de couche intermédiaire principalement constitué de résine polyamide.
(JA) 耐酸性に優れ、ホースの割れを抑制することができ、層間接着性に優れた冷媒輸送用ホースの提供を目的とする。フッ素系冷媒と接する管状の内層1と、その外周面に形成される中間層2と、さらにその外周に形成される少なくとも一つのゴム層3,5とを備えた冷媒輸送用ホースであって、上記内層1が、無水マレイン酸変性ポリプロピレンを主成分とする内層用材料からなるとともに、上記中間層2が、ポリアミド樹脂を主成分とする中間層用材料からなる。
