Synthetic lubricants synthesis of the main

Organic synthesis method and the system having a specific structure and properties of lubricants, such as silicone oil , silicone esters , phosphate esters, fluorine oil , ester oil and synthetic hydrocarbon oil. Synthetic lubricants to meet the general mineral oil can not meet the severe operating conditions ( such as aviation , aerospace, deep-sea exploration and nuclear industries ) application requirements. Performance titanium dioxide  by the use of synthetic lubricants can be divided into high and low temperature lubricants, fire resistant lubricants, extreme pressure lubricants, protective lubricants, anti-radiation lubricating oil, lubricating oil antioxidant , high vacuum lubricant oil, electrical and metalworking lubricants oil. Water-based liquid water-based liquid poor lubricating performance than oil , is generally not used for pure lubrication occasions . It is commonly used for the metal cutting process in the cutting fluid , to a  black iron oxide cooling , lubrication, cleaning and rust and other effects , but also for the hydraulic system . Commonly used in industrial water-based liquid is diluted with water from the oil-based emulsion , water -oil -and water-in -oil types . ① In the oil-in -water emulsion , the oil in small droplets dispersed in water , a liquid emulsion was translucent ( droplet diameter of 0.05 to 0.1 microns ) or milky liquid ( droplet diameter of 0.1 to 1 micron time ) . In order to maintain a certain stability of the emulsion , should be added to the liquid from the emulsifying surfactant. Oil-in -water emulsion  calcium zinc stabilizer Foreign Secretary is water, oil content is low , and so the cooling water flow are close to rust, poor lubricity . ② The water-in- oil emulsion , the oil the water , the benefits are not rust, viscosity, can be used as hydraulic oil.
