含水95％以上的高水基工作液(HWBF)代替石油类工作液,是当前发挥水的优越性和引人注目的课题。欧美国家的各行业在三年前就积极采用高水基工作液,从钢铁、汽车业开始,已发展到锻造、食品、橡胶硫化等一般机械上,日本各行业也在研究其实用价值。高水基工作液之所以受到人们的重视,是因为1973年石油危机以后,有关高水基工
Water-based high-water-based working fluid (HWBF), which contains more than 95% of water, replaces the oil-based working fluid and is an issue that attracts attention currently. Various industries in Europe and the United States actively used high-water-based working fluids three years ago. Starting from the steel and automobile industries, they have developed into general machinery such as forging, food and rubber vulcanization. Japanese industries are also studying their practical value. The reason why high water-based working fluid is valued by people is that after the oil crisis in 1973, the high-water-based workers
