作为液压制动装置的工作介质——制动液是确保车辆具有良好制动性能的关键。早期的制动液用糖水、润滑油等。三十年代开始大量使用蓖麻油和醇的混合物。随着汽车工业的发展,制动液品种、规格不断完善。出现了醇醚型制动液、低吸湿性制动液、硅油型制动液等。为保证制动系正常工作,对制动液性能的要求是多方面的,但平衡回流沸点(简称沸点),
As a working medium for the hydraulic brake, brake fluid is the key to ensuring a good braking performance of the vehicle. Early brake fluid with syrup, lubricants and so on. Thirty time began to make extensive use of castor oil and alcohol mixture. With the development of automobile industry, brake fluid varieties, specifications continue to improve. There have been alcohol-based brake fluid, low hygroscopic brake fluid, brake fluid silicone oil type. To ensure the normal work of the braking system, the brake fluid performance requirements are many, but the balance of reflux boiling point (referred to as boiling point)
