蓖麻油-醇型制动液已不用,矿物油型制动液目前已逐步停用,合成型制动液应用广泛。合成型制动液是用醚、醇、酯等掺入润滑、抗氧化、防锈、抗橡胶溶胀等添加剂制成的,工作温度范围较宽,低温下易流动,制动灵活,沸点高,高温下蒸发损失小、不易产生气阻,对金属件和橡胶件腐蚀性小,因而得到广泛应用。
Castor oil - alcohol type brake fluid has not, mineral oil type brake fluid has been gradually disabled, synthetic brake fluid is widely used. The synthetic brake fluid is made of additives such as ether, alcohol, ester, etc., which are lubricated, anti-oxidation, anti-rust and anti-rubber swelling. The working temperature range is wide, easy to flow at low temperature, High temperature evaporation loss is small, not easy to produce gas resistance, corrosion of metal parts and rubber pieces of small, so widely used.
