小行星9816247 虽然金属铸造工艺通常是生产复杂净成形零件所需的,但由于铸造操作的环境空气质量法规,挥发性烃的排放对工业造成越来越严重的限制。这些排放物来自于型砂和芯砂中有机粘结剂的热解。该探索性小额赠款(SGER)项目建议通过寻找合成碳酸盐水泥替代品来研究模具制造所需的粘合剂的重新配制。这种材料将允许用于铸造工艺的二氧化硅颗粒的结合,通过替代更温和的材料减少挥发物。 该SGER将证明合成材料在金属铸造中常见的条件下作为粘合剂替代品的能力。 该实验将提供必要的信息,以证明该材料作为成型剂的适用性,包括用于废物流处理的铸造后材料特性。 这是一个新的方法来解决一个重大的环境问题的制造业社区。 如果能够满足成型和铸造后废物处理的预期性能,则其使用潜力很大。
英文摘要
9816247Groza Although the metal casting process is often desirable for the production of complex netshape parts, the emission of volatile hydrocarbons has placed increasingly severe restrictions upon the industry as a result of ambient air quality regulations on foundry operations. These emissions arise from the pyrolysis of the organic binders in the mold and core sand. This Small Grants for Exploratory (SGER) project proposes to investigate the reformulation of the binders that are necessary for the mold-making, by looking to a synthetic carbonate cement alternative. This material would allow bonding of the silica particles for the casting process with a reduction in the volatiles by the substitution of more benign materials. This SGER will demonstrate the ability of the synthetic to serve as a substitution for the binder under conditions typically found in metal casting. This experimentation will provide the information necessary to demonstrate the suitability of the material as a molding agent, including the post-casting material characteristics for waste-stream handling. It is a novel approach to a significant environmental problem for the manufacturing community. There is high potential for its use if the expectations of properties for molding and for post-casting waste handling can be met.
