The objective of this Small Grant for Exploratory Research is to investigate the feasibility of using a novel collagen protein-based binder to reduce foundry emissions. A considerable fraction of foundry emissions occurs when conventional phenolic urethanes that bind mold cores release VOCs when pyrolyzed at high temperatures. Cores are made of silica sand grains that are held together by binders. The new collagen protein binder examined herein releases 1/4 to 1/3 as much VOC emissions as do conventional binders but they are not as tough. Thus poured molten metal will more readily erode the collagen-binded cores. In this study, UV light irradiation of the collagen protein will be used in an attempt to toughen the collagen skin and improve its ability feasibility for use in molten processes. If successful, the research will provide fundamental understanding of UV radical reactions with collagen and its use as a binder of VOCs during molten metal processing. The impact of reduced emissions from foundries is enormously important. The proposal team anticipates that a successful implementation of this research can result in a 40-60% reduction in VOC pollution from foundries.

这项探索性研究小额资助的目的是研究使用新型胶原蛋白粘合剂来减少铸造厂排放的可行性。铸造厂排放的很大一部分是由于粘合模芯的传统酚醛聚氨酯在高温热解时释放挥发性有机化合物而产生的。芯由硅砂粒制成，通过粘合剂粘合在一起。本文研究的新型胶原蛋白粘合剂释放的 VOC 排放量是传统粘合剂的 1/4 至 1/3，但它们没有那么坚韧。因此，注入的熔融金属将更容易侵蚀胶原蛋白结合的核心。在这项研究中，将使用胶原蛋白的紫外线照射来尝试使胶原蛋白表层变韧并提高其在熔融工艺中使用的能力和可行性。如果成功，该研究将为胶原蛋白与紫外线自由基反应及其在熔融金属加工过程中作为挥发性有机化合物粘合剂的用途提供基础了解。铸造厂减少排放的影响非常重要。提案团队预计，这项研究的成功实施可以使铸造厂的 VOC 污染减少 40-60%。
