随着液压技术的迅速发展,国外在使用石油基工作油的过程中发生了许多严重的火灾,造成的损失很大,因此近三十年来逐渐发展了抗燃工作油,主要用于接近火源或高温的液压设备中。美国1974年工业用工作油用量约为75万吨,其中抗燃工作油用量约占5～10％。日本磷酸酯及水-乙二醇两类抗燃工作油的总用量1967年约为1100吨,1971年增长为5000吨左右,约相当于石油基工作油用量的3％。目前,抗燃工作油已用于冶金、金属加工、矿业、发电、机械制造、木材、塑料、航空、船运及管道输送等部门,预计其使用范围还将不断扩大。
With the rapid development of hydraulic technology, many serious fires occurred in the process of using petroleum-based working oil abroad, resulting in great losses. Therefore, the anti-flammable working oil has been gradually developed in the past three decades and mainly used in the fields close to the sources of ignition Or high temperature hydraulic equipment. The United States in 1974 the amount of industrial working oil is about 750,000 tons, of which the amount of fire-resistant working oil accounts for about 5 to 10%. In Japan, the total amount of phosphate ester and water-ethylene glycol fire-resistant working oil was about 1,100 tons in 1967 and about 5,000 tons in 1971, equivalent to about 3% of the amount of petroleum-based working oil. At present, anti-burn oil has been used in metallurgy, metal processing, mining, power generation, machinery manufacturing, wood, plastic, aviation, shipping and pipeline transportation and other departments are expected to continue to expand its use.
