Chemical Name: Calcium Oxide (Quicklime)
Molecular Formula: CaO
Molecular Weight: 56.08
CAS Number: 1305-78-8
High Purity: With a calcium oxide content of 98%, this product minimizes impurities, ensuring superior performance in demanding industrial and specialized applications.
Physical Form: Available as fine white powder or solid lumps. Powdered quicklime offers a large surface area for rapid reactions, while lumps enhance ease of storage and transportation, allowing on-site customization.
Bulk Density: Typically 0.6 - 0.8 g/cm³, optimizing stability during storage and facilitating accurate measurement and application.
98% high - content quicklime, as an additive, plays a significant role in the production of high - grade lubricating grease.
Regulating Consistency and Structure
Participating in Saponification Reaction: Quicklime reacts with fatty acids through the saponification reaction to form calcium soaps, which are important thickeners for lubricating grease. Taking palmitic acid as an example, it reacts with calcium hydroxide (formed by quicklime reacting with water) to produce calcium palmitate. These calcium soaps form a three - dimensional network structure in the base oil, enclosing the base oil within it, thus giving the lubricating grease a specific consistency and shape. By controlling the amount of quicklime added, the amount of calcium soap produced can be accurately adjusted, thereby controlling the consistency of the lubricating grease to meet the requirements of different application scenarios. For example, the lubricating grease used for high - speed bearings requires a lower consistency, so the amount of quicklime added will be relatively small.
Improving Colloidal Stability: An appropriate amount of quicklime helps to improve the dispersibility and stability of calcium soaps in the base oil, making the colloidal structure of the lubricating grease more uniform and stable. This can prevent the oil - soap separation of the lubricating grease during storage and use, ensuring the consistency of the lubricating grease performance and its long - term usability.
Enhancing Lubrication Performance
Reducing Friction and Wear: The quicklime additive can form a dense adsorption film on the metal surface, which has good lubricity and can reduce the friction coefficient between the friction pairs. When mechanical equipment is running, it can effectively reduce the direct contact and wear between metal parts. For example, in the crankshaft bearings of automobile engines, the use of high - grade lubricating grease containing quicklime additives can significantly reduce the wear of the bearings, prolong their service life, and also reduce the energy loss of the engine, improving fuel economy.
Strengthening Oil Film Strength: Quicklime can change the arrangement and interaction of molecules in the lubricating grease, making the oil film formed by the lubricating grease on the metal surface more solid and stable. Under harsh conditions such as high load and high speed, the oil film can withstand greater pressure without breaking, thus ensuring the lubrication effect of the lubricating grease and preventing dry friction and increased wear. It is suitable for the lubrication of large - scale heavy - duty equipment in industrial production.
Improving Protection Performance
Neutralizing Acidic Substances: Lubricating grease will produce acidic substances due to oxidation, hydrolysis, and other reasons during use, and these acidic substances will corrode metal parts. Quicklime is strongly alkaline and can neutralize these acidic substances, playing a role in protecting metals. For example, in some chemical equipment, due to the acidic gas in the working environment, the use of lubricating grease containing quicklime additives can effectively neutralize the infiltrated acidic substances and prevent equipment corrosion.
Water - proofing and Moisture - proofing: Quicklime is hygroscopic and can absorb the water in the lubricating grease and the water that penetrates from the outside, reducing the water content of the lubricating grease. At the same time, it can also improve the structure of the lubricating grease, making it more hydrophobic and forming a waterproof barrier to prevent water from damaging the performance of the lubricating grease and avoid the emulsification and deterioration of the lubricating grease due to water absorption. It is suitable for working scenarios in humid environments or in contact with water, such as the propulsion systems of ships, sewage treatment equipment, etc.
Optimizing Oxidation Stability
Inhibiting Oxidation Reaction: Quicklime can react with the peroxides and free radicals produced during the oxidation of lubricating grease, preventing the further development of the oxidation reaction. It can decompose peroxides into stable compounds, reducing the accumulation of oxidation products, thereby slowing down the oxidation rate of lubricating grease and prolonging its service life. For example, in equipment working in high - temperature environments, the use of lubricating grease containing quicklime additives can effectively resist oxidation and maintain good lubrication performance.
Passivating Metal Ions: Quicklime can form complexes with metal ions (such as iron, copper, etc.) in the lubricating grease. These metal ions usually catalyze the oxidation reaction of the lubricating grease. Through the complexation effect, quicklime passivates the metal ions, reducing their catalytic activity, thereby improving the oxidation stability of the lubricating grease, enabling the lubricating grease to maintain good performance during long - term use, and reducing performance degradation and equipment failures caused by oxidation.
