Abstract
本发明公开了一种可稀释循环回收使用光伏硅晶片线切割液，由高级醇、有机胺、表面活性剂、纯水组成。本发明工作性能好、使用安全。
Description
技术领域
本发明涉及一种光伏硅晶片线切割液。
背景技术
使用传统的游离磨粒加工方式加工时，由于切屑粉末不易分散，悬浮性差，易粘附在机器和刀具表面，影响切削加工；同时工作液中还存在大量固体颗粒废弃物，增加排放量。
传统使用的光伏硅晶片线切割液产品目前有两种：一种为原液型线切割液，可循环回收使用，但不能稀释使用。由于产品不能稀释使用，且循环回收率又不高（＜75%），所以使用成本较高；另一种为稀释型线切割液，可稀释使用，但不能循环回收使用。虽然稀释使用单次成本较低，但由于不能循环回收使用，所以使用成本仍然较高。
目前光伏企业使用的线切割液，配方中均含有有毒物质，危害人体健康和环境安全。
发明内容
本发明的目的在于提供一种工作性能好、使用安全的可稀释循环回收使用光伏硅晶片线切割液。
本发明的技术解决方案是：
一种可稀释循环回收使用光伏硅晶片线切割液，其特征是：由下列重量百分比的成分组成：
高级醇…………………………50～80％
有机胺………………………………0-1％
表面活性剂…………………………1～20％
纯水…………………………………10～35％。
所述高级醇是丙醇、异丙醇、丁醇、丙二醇、丙三醇、十二碳醇、十四十五碳醇中的一种或几种。
有机胺是一乙醇胺、一异丙醇胺、二异丙醇胺、三异丙醇胺、N-甲基吗啉、2-氨基-2-甲基-1-丙醇、二乙胺基乙醇中的一种或几种。
表面活性剂是脂肪醇聚氧乙烯醚（5～12）、脂肪醇聚氧乙烯聚氧丙烯醚、聚氧乙烯聚氧丙烯醚（5～12）、烷基醇酰胺、脂肪醇聚氧乙烯酯（5～12）、聚萘甲醛磺酸钠盐中的一种或几种。
本发明采用固定磨粒加工方式（替代传统使用的游离磨抗加工方式），分散性好（切屑粉末可长时间均匀地分散悬浮在工作液中，切屑沉降时间≥5min）。
本发明采用高级醇、高级表面活性剂等设计配方，产品不仅可稀释使用（稀释液浓度达到20%），而且可循环回收使用（回收率≥92%）。
本发明安全卫生质量高。采用生物可降解度高、对人和环境友好的可替代物质设计配方，产品生物半致死量LD50≥5000mg/kg，半致死浓度LC50≥5000ml/m3，呼吸道粘膜刺激≤1级。
下面结合实施例对本发明作进一步说明。
