Title (EN) OIL RECOVERY AGENT, OIL DISPERSION LIQUID, AND OIL RECOVERY METHOD
(FR) AGENT DE RÉCUPÉRATION D’HUILE, LIQUIDE DE DISPERSION D’HUILE, ET PROCÉDÉ DE RÉCUPÉRATION D’HUILE
(JA) 油回収剤、油分散液及び油回収方法
Abstract:
(EN) The present invention provides an oil recovery agent that has properties for reducing the viscosity of oil and improving fluidity (viscosity reduction properties) and properties for quickly separating after dispersion in oil (immediate separation properties), and that enables quick recovery of oil. This oil recovery agent contains a polyvinyl-alcohol-based resin in which the water contact angle when the resin is formed into a film is 70° or smaller.
(FR) La présente invention concerne un agent de récupération d’huile qui présente des propriétés de réduction de la viscosité d’une huile et d’amélioration de la fluidité (propriétés de réduction de viscosité) et des propriétés de séparation rapidement après dispersion dans l’huile (propriétés de séparation immédiate), et qui permet la récupération rapide de l’huile. Cet agent de récupération d’huile contient une résine à base de poly(alcool de vinyle) dans laquelle l’angle de contact avec l’eau lorsque la résine est mise en forme de film est de 70 ° ou moins.
(JA) 本発明は、油の粘度を低減して流動性を改善する性質(減粘性)、かつ油中に分散後に速やかに分離する性質(即時分離性)を持ち、速やかに油を回収できる油回収剤を提供する。本発明の油回収剤は、フィルムにした際の水接触角が70°以下のポリビニルアルコール系樹脂を含有する。
