Principle of Calcium Oxide in Lubricating Grease
Lubricating grease is typically composed of base oil, thickener, and additives. The main functions of calcium oxide (CaO) are as follows:
As a raw material for thickeners: Calcium oxide reacts with fatty acids (such as stearic acid, oleic acid, etc.) to form calcium soaps (e.g., calcium stearate), which are key thickeners for calcium-based lubricating grease. These soaps enable the base oil to form a semi-solid grease structure.
Regulating alkalinity: Calcium oxide is alkaline and can neutralize acidic substances (such as organic acids generated by oxidation) in the grease, thereby improving the antioxidant property and service life of the grease to a certain extent.
99% high-purity calcium oxide (CaO), with extremely low impurity content, demonstrates significant advantages in chemical, material, environmental protection and other fields, especially suitable for application scenarios with strict purity requirements.
For example, in fine chemical reactions such as transesterification and condensation, high-purity calcium oxide as a basic catalyst can reduce side reactions (such as isomerization reactions induced by impurities) and improve the yield of target products. For instance, in biodiesel production, every 1% increase in purity can enhance the transesterification conversion rate by 0.5%-1%.
