随着我国煤矿高挡普采技术的广泛采用与推广,外注式单体液压支柱(以下简称液压支柱)用量日益增加。据中国统配煤矿总公司统计,1991年已达210万根,初步估称每年需用乳化油5000t左右。液压支柱的乳化液,被人们称为液压支柱的“血液”。它不但要起到力的传递作用,而且对液压支柱的各部件要起到保护作用。因此,乳化液必须要有良好的防锈性、 With the widespread adoption and popularization of high-grade general mining technology in China’s coal mines, the amount of extra-type single hydraulic props (hereinafter referred to as hydraulic props) is increasing. According to the statistics of China General Coal Mine Corporation, it reached 2.1 million in 1991, initially estimating that 5000t of emulsified oil will be required each year. Hydraulic props emulsion, known as hydraulic props “blood.” It not only plays the role of force transmission, but also protects the components of hydraulic props. Therefore, the emulsion must have good anti-rust properties,
