PMMA (polymethyl methacrylate) is a thermoplastic polymer whose melting point is not a clear temperature, but shows softening and flow characteristics between 200°C and 240°C (glass transition temperature 𝑇𝑔 is 105°C – 120°C). The following is a relevant analysis of PMMA mixed with paraffin under high temperature conditions: Strictly speaking, PMMA does not really “melt”, Read more

To address the potential antagonistic effects between sulfurized esters and Zinc Dialkyl Dithiophosphate (ZDDP) in lubricant formulations, the following strategies are typically employed: 1. Careful Optimization of Additive Dosage 2. Colloidal and Solubility Stability Testing 3. Use of Secondary or Synergistic Additives 4. Testing Under Operational Conditions 5. Antagonism Mitigation via Additive Surface Chemistry 6. Read more

To transform recycled motor oil into a base engine oil suitable for use in motorcycles and taxis, several additives are typically incorporated to restore or enhance the oil’s properties. These additives ensure that the recycled oil meets the performance and protection requirements needed for high-demand applications like motorcycles and taxis. Here are the key additives Read more

Improving the quality of recycled engine oil, often referred to as re-refined or reclaimed oil, involves several critical steps to ensure that the oil meets the necessary performance standards and can be effectively reused. Here are the key processes and additives that can help improve the quality of recycled engine oil: 1. Effective Contaminant Removal Read more

When sulfonic acid, base oil, concentrated acetic acid, acetic acid, calcium carbonate and distilled water are mixed, a series of complex chemical reactions may occur. The specific products generated depend on the reaction conditions (such as temperature, stirring, reaction time) and the ratio of each component. The following are the main reactions that may occur Read more

The synthesis of TBN 400 super high-base calcium sulfonate involves a complex overbasing process, where alkaline earth metal (typically calcium) is reacted with sulfonic acid or sulfonate detergent, carbon dioxide (CO₂), and a promoter in the presence of oil and base stock solvents. This process produces a highly basic, colloidal calcium carbonate dispersed in an Read more
