Title: Innovations of Dong Yeol Choi in Antifreeze Technology.
Introduction
Dong Yeol Choi is a notable inventor based in Gyeonggi-do, South Korea. He has made significant contributions to the field of antifreeze liquids and coolants, holding 2 patents that showcase his innovative approach to enhancing corrosion resistance and pH buffering properties.
Latest Patents
One of his latest patents is a composition having enhanced corrosion resistance and pH buffering property for antifreeze liquid or coolant. This composition includes a cyclo hexane dicarboxylic acid, an azole- or thiazole-based inhibitor, and a metal from groups 2, 5, 6, or 7. The invention boasts increased corrosion resistance at a lower density by excluding organic additives, while also providing better pH buffering due to enhanced thermal oxidation stability at high temperatures. Remarkably, even after long-term operation exceeding 200,000 km, the composition maintains its metal corrosion resistance capability, ensuring that components like water pump impellers and radiator tubes remain in good condition.
Another significant patent by Choi is a composition for antifreeze liquid or coolant that exhibits superior cavitation erosion and gap corrosion resistance. This invention comprises a glycol-based antifreeze agent, a cyclo hexane dicarboxylic acid, and a non-reduced polyol. By utilizing both the cyclo hexane dicarboxylic acid and the non-reduced polyol in parallel, a synergy effect is achieved, resulting in exceptional corrosion prevention against cavitation erosion and gap corrosion within cooling apparatuses.
