At present, the formula used in metal processing oil (liquid) in my country is still relatively backward, and many toxic and hazardous materials are still in use today. This is undoubtedly a serious problem for environmental pollution and the health of operators. Therefore, environmentally friendly metal processing oil (liquid) is the general direction of development. The future development direction of metal processing liquid must be non-toxic, low odor and low oil mist. , Long life, low waste treatment cost, and strong biodegradability. Oleic acid ester has a wide range of applications in metalworking fluids. Instead of vulcanized lard in traditional formulations, refined lard and fatty acids can improve the lubricating properties, environmental protection, and service life of metalworking fluids. Commonly used oleic acid The esters mainly include trimethylolpropane oleate and monoquaternary oleate. Whether the hydraulic system can work reliably, efficiently and economically depends to a large extent on the performance of the hydraulic oil. HFDU is not only a perfect fire-resistant hydraulic oil but also a green and environmentally friendly hydraulic oil. Today, when human beings pay more and more attention to environmental protection, green and environmentally friendly flame-resistant hydraulic oil will definitely become an inevitable trend in the development of hydraulic oil.
Applications A. A well-known domestic lubricating oil manufacturer has been supplying fire-resistant hydraulic fluids to a large domestic steel plant, using phosphate ester-type fire-resistant hydraulic fluids (HFDR). Due to the decline in the benefits of steel plants and environmental protection, etc. The requirements of various aspects continue to increase. The steel plant proposed to reduce costs and adopt more environmentally friendly and non-toxic flame-resistant hydraulic fluid. The lubricating oil plant eventually replaced the oleic acid ester type of flame-resistant hydraulic fluid, using CRODA oleate 2101 ( Made 46# fire-resistant hydraulic oil) and 2722 (made 68# fire-resistant hydraulic oil), which not only guarantees the performance of the oil, but also meets the steel mill’s requirements for cost reduction and environmental protection. B. Used in metal processing oil formulations to replace materials such as vulcanized lard and tall oleic acid, it can improve the lubricity of the oil, prolong the service life of the processing oil, and reduce the oil's physical damage to the operators. A domestic metalworking fluid manufacturer previously used a large amount of sulfurized lard in the process oil provided by the downstream metal processing plant. The downstream plant complained that the process oil had an excessive smell and the workers could not tolerate it. Later, it switched to trimethylolpropane oleate. The formula, using CRODA trimethylolpropane oleate 2101, successfully solved the customer's problem. Although the cost has been increased, the oil has a longer service life, and the overall use cost has not increased. Introduction to common oleic acid esters Trimethylolpropane oleate has excellent lubricating properties, high viscosity index, good flame resistance, and a biodegradation rate of more than 90%. TMPTO-B/C can be used as an oily agent in cold-rolled sheet rolling oil, steel pipe It is widely used in drawing oil, cutting oil and other metal working fluids. It can also be used as an intermediate of textile leather auxiliaries and textile finishing agents. Monopentaerythritol oleate has excellent lubricating properties, high viscosity index, good flame resistance, and a biodegradation rate of more than 90%. It can be used to formulate environmentally friendly hydraulic oil, chain saw oil and engine oil for marine yachts; as an oily agent It is widely used in wire drawing oil, steel pipe drawing oil, cutting oil and other metal working fluids. Monopentaoleate has good surface film-forming properties, and can also be used as an intermediate for textile leather auxiliaries and textile oiling agents.
