Breaking the Adhesive Bond between Dialyll Phthlate, Barco Bond 185 and PBX 9501

引用

Journal of Materials Science and Chemical Engineering 2015年第7期3卷 196-201页

作者： Matt Jackson Benton Allen Trent Kelly Courtney Waddell Emily M. Hunt Stephanie steelman Neil Koone West Texas A & M University Canyon Texas USA CNS Pantex Amarillo Texas USA

Use of epoxy as an adhesive is a common practice. The most common applications are permanent sealants. Epoxies have a wide range of operating temperatures, and are very resistance to adhesive failure. When a need to remove this adhesive arises, it is not always easily accomplished especially if the part has excessive adhesive. To maintain fidelity of the parts attached by epoxy, a project evaluating several methods of epoxy removal was conducted. Methods evaluated included low wavelength, near-ultraviolet radiation, solvent dissolution, and thermal cycling. The UV method failed to demonstrate a repeatable dissociation. The solvent study did result in dissociation of bonds, but introduced chemicals that could make subsequent chemical analysis of parts suspect. Thermal cycling showed a high repeatability for dissociation of bonds and may prove to be relatively inexpensive to implement.

1980年代，社区环境管理（CBEM：community-based environmental management）作为处理棘手环境问题的创新途径在美国开始出现。CBEM指的是地方团体采用与各类代理机构、地方政府或其他组织以合作方式处理环境问题。为更好地理解这一流行的环境管理手段．本文首先回顾环境管理制度的演变以及影响CBEM过程的资源变化．在此基础上，本文建构了关于CBEM过程的评估框架．并列举了两个通过发起CBEM来治理酸性矿物废水对流域污染的案例。
