使用过的固定磨料钢丝锯用切削液组合物的处理方法
Abstract:
一种使用过的固定磨料钢丝锯用切削液组合物(以下，简称为“切削液组合物”。)的处理方法，其中，使用前的切削液组合物含有特定的聚醚化合物(成分A)25～75重量％、特定的表面活性剂(成分B)1～9重量％、和水(成分C)，切削液组合物的浊点为30～80℃，从排油液中至少除去切削粉末的粉末除去工序包括：第一工序，将排油液加热至切削液组合物的浊点以上的温度，分离成以聚醚化合物为主要成分的上层、及以水和切削粉末为主要成分的下层；以及第二工序，从分离后的所述排油液中除去下层。
Abstract(English):

A method for processing a used cutting oil composition for a fixed abrasive wire saw ("cutting oil composition"), wherein: the cutting oil composition before use contains 25-75 wt% of a specific polyether compound (component A), 1-9 wt% of a specific surfactant (component B), and water (component C); the cloud point of the cutting oil composition is 30-80 DEG C; and a powder removal step for removing at least cutting powder from waste oil liquid comprises a first step for separating an upper layer having the polyether compound as a main component and a lower layer having water and cutting powder as main components by heating waste oil liquid at or above the cloud point of the cutting oil composition, and a second step for removing the lower layer from the separated waste oil liquid.
