Furthermore, in the manufacture of lubricating grease, calcium naphthenates play an extraordinary role. It can optimize the performance of lubricating grease, such as improving its water resistance and mechanical stability. When the machine is running, the lubricating grease often encounters water-wet environment and mechanical stress, and has good water resistance and mechanical stability, so as to ensure the lubrication effect lasts for a long time, reduce mechanical wear and prolong its service life.
It can also be seen in the agricultural field. It can be made into an agricultural emulsifier, which can help the pesticides to be evenly dispersed in the water, improve the uniformity of pesticide spraying, increase the efficacy, and reduce the amount of pesticides. It not only protects crops from pests and diseases, but also protects the environment from pesticide pollution.
In many aspects of chemical production, calcium naphthenates have become indispensable materials for the development of various industries due to their unique properties.
What is the production process of Calcium Naphthenate?
The production process of calcium naphthenates has been around since ancient times. The method began with exquisite skills and has been passed down and improved.
The first naphthenic acid is extracted, which is a genus of natural fatty acids, mostly derived from the remaining naphthenic acid oil from petroleum fractionation. The method of extraction and distillation is used to remove its impurities and improve its purity to achieve high quality.
Then take calcium sources, usually calcium hydroxide and calcium oxide. Put the refined naphthenic acid and calcium source in an appropriate proportion in the reactor. Add an appropriate amount of solvent to the kettle to make the two blend evenly to facilitate the reaction.
When reacting, control its temperature and pressure. It is often heated moderately to promote the reaction to accelerate, but it should not be overheated to prevent the product from deteriorating. The pressure should also be moderate to ensure the stability and smoothness of the reaction.
After the reaction is completed, the product is separated and purified. Or use filtration to remove its insoluble matter; or use distillation to remove its solvent and unreacted matter. Then through the drying process, pure calcium naphthenate is obtained.
The obtained calcium naphthenate is of excellent quality and is widely used in many fields. If used as a drying agent for coatings and inks, it can be dried to form a film; in lubricating oils, it can increase its anti-wear and anti-rust ability. This process has been passed down from generation to generation, and it is a treasure in the industry.
