Background technique

With the rapid development of the economy and the improvement of people's quality of life, the pharmaceutical industry has also developed rapidly, which has promoted the progress of pharmaceutical machinery technology and promoted the upgrading of the pharmaceutical equipment industry. Pharmaceutical industry machinery and equipment is an important part of the chemical machinery field. Due to the special working conditions of pharmaceutical machinery and equipment, it has an important direct impact on the quality of pharmaceuticals, especially the lubricating oil used in machinery and equipment.

At present, my country's pharmaceutical machinery enterprises generally present the characteristics of scattered distribution, small scale, relatively backward technology, and unsuitable equipment. A considerable part of pharmaceutical machinery and equipment products is extensive, and lubricants consume too much energy; pharmaceutical machinery manufacturing and maintenance technology is relatively backward. ; The awareness of environmental protection is weak, and the awareness of lubricants for mechanical equipment that may eventually affect product quality in the pharmaceutical process is insufficient. Therefore, my country's pharmaceutical machinery enterprises should take the road of sustainable development with high technology, energy saving, environmental protection and high intensity.

Today, machinery and equipment in the pharmaceutical industry require lubricating oils to meet the following requirements: non-toxic, biodegradable, high oxidation resistance, long life, low pour point, high viscosity, and special occasions that can adapt to severe cold and high temperature conditions. Due to the good biodegradability of vegetable oil, more and more people pay more and more attention to it. The base oil of lubricating oil produced from vegetable oil has the advantages of renewable, biodegradable, non-toxic, and good lubricating performance, but vegetable oil used as base oil has the following disadvantages: poor oxidation stability, weak thermal stability, hydrolytic stability and Low temperature performance is poor, therefore, generally do not directly use vegetable oil as base oil.
