摘　　要：针对水基金属加工液容易产生细菌从而导致加工液失效的问题,研究了不同种功能性添加剂对金属加工液抑菌性的影响。将现场取回的已失效加工液进行扩菌培养,采用测菌片测试菌数含量,通过电子显微镜观察微生物被抑制情况,对比了多种添加剂及其复配组合的抗菌性能。实验结果表明,5%BA、3%DCHA与2%MBM三种添加剂复配的抑菌效果最佳,由于特种胺与硼酸的加入,有效地提升了加工液体系的抗菌性能。通过分析各类添加剂的抑菌机理,探讨了添加剂复配后产生的协同效应,得出不同类型添加剂的有效组合对增强加工液的抗菌性具有积极作用。Aiming at the problem that water-based metalworking fluids are contaminated by microorganism,which can lead to fluid failure,this study was conducted to investigate the effect of different functional additives on the microbiocidal property of metalworking fluids.The waste metalworking fluids collected from the site was cultured to expand microorganism.The bacterial content was tested by bacterial counting slides,and the microorganism inhibition was observed under an electron microscope,to compare the microbiocidal properties among various additives and their compound combinations.Experimental results show that the combination of three microbicides,namely 5%BA,3%DCHA,and 2%MBM,exhibits the best microbiocidal effect.Adding special amines and boric acid effectively enhances the microbiocidal performance of metal working fluids.By analyzing the microbiocidal mechanisms of various additives,it is explored that the synergistic effect of the various additives compounding has a positive effect on enhancing the microbiocidal properties of metalworking fluids.
