Title: The Innovative Contributions of Therese A. Espinoza
Introduction
Therese A. Espinoza, an accomplished inventor based in Wood Dale, IL, United States, has made significant contributions to the fields of building materials and construction through her five innovative patents. Her work primarily focuses on advancements in plaster technologies, particularly enhancing the hydration processes and setting times essential for construction applications.
Latest Patents
Espinoza's latest patents exemplify her innovative prowess. One notable patent is the "Efficient Set Accelerator for Plaster," which describes a set accelerator aimed at boosting the hydration rate and minimizing the set time of aqueous slurry composed of calcium sulfate hemihydrate. This set accelerator is composed of a blend of ground calcium sulfate dihydrate and zinc sulfate material, with aluminum sulfate being an optional ingredient. This technology proves especially beneficial for accelerating hydration rates in sprayable plasters, and a fluid version of the accelerator can be created by suspending the solids in water, making it ideal for ready-mixed setting-type joint compounds.
Another significant patent is her invention of a "Clay-Free Ready-Mixed Setting-Type Joint Compound." This two-part joint compound sets through the hydration of calcium sulfate hemihydrate to gypsum and is devoid of clay. The first part contains an in-situ acidic acrylate copolymer thickener and a non-calcium bearing phosphate set preventer, allowing it to remain unset for up to 175 days. The second part features a set initiator compound, designed to initiate the setting process only when mixed with the first part.
Career Highlights
Therese A. Espinoza is currently employed at the United States Gypsum Company, where she continues to develop cutting-edge materials that enhance construction efficiency. Her innovative spirit and dedication to improving industry standards are evident in her extensive work and patent portfolio.
