AI Technical Summary
Existing paraffin-based investment casting materials are prone to decomposition and high volatility at high temperatures, leading to a decrease in casting precision and surface quality, as well as serious pollution, which affects production efficiency and yield.
Using polyvinyl butyral resin as the matrix, compounded with paraffin, talc and diatomaceous earth, the component ratio is optimized, and bio-based plasticizers, nano-alumina and silicon carbide are added. The molding material is prepared through a synchronous mixing process to improve high temperature stability and reusability.
It significantly improves the high-temperature stability and reusability of mold materials, reduces harmful gas emissions, enhances casting precision and surface quality, and lowers production costs.
