SBIR Phase II: Development of a New High Intensity Pulsed Light Source System

该小型企业创新研究(SBIR)二期项目旨在进一步研究大电流脉冲操作下电极材料的腐蚀特性，并展示一种新型脉冲灯的延长寿命，使其具有经济实用价值。随着寿命的增加，这种新的灯可以成为紫外线水处理的行业标准，并实现一种新的光解剥漆工艺。用于脉冲功率电极的材料最初是用来在低峰值电流下连续或交流的。在第一阶段，采用特定工艺制备的钨复合材料的腐蚀量为标准电极材料的十六分之一。第二阶段继续研究这种钨复合材料及其制造工艺，以展示低侵蚀，目的是展示满足商业化要求的更长的灯寿命。如果成功，拟议的研究将加强对电极材料在反复大电流脉冲循环下的侵蚀的科学理解。新的电极材料将扩大脉冲功率的使用，并提供更好的替代卤化钨的方法，后者在欧洲因其放射性而被禁止。主要目标是实现一种新的商用脉冲灯。该灯将取代汞灯，减少汞的使用和公众的暴露。该灯还将实现商业光解涂料的去除，取代劳动密集型的化学和研磨技术，产生灰尘和碎片，并产生有毒副产品。光解过程将提供一种成本更低、更清洁的去除含铅涂料的方法。这将使减排措施取代目前流行的“临时措施”，并支持消除儿童铅中毒的国家目标。这种新型灯的商业市场涵盖了所有UV水处理和广泛的油漆去除应用。

This Small Business Innovation Research (SBIR) Phase II project is to conduct further research on the erosion properties of electrode materials under high-current pulsed operation, and demonstrate extended lifetime for a new pulsed lamp, making it economically practical. With increased lifetime, the new lamp can become the industry standard for UV water treatment and enable a new photolytic paint stripping process. Materials used for pulsed power electrodes were originally formulated for continuous or alternating current at low peak current. In Phase I a tungsten composite fabricated with a specific process eroded at one-sixteenth of the erosion of the standard electrode material. Phase II continues the research on this tungsten composite and its fabrication processes to demonstrate low erosion, with the objective of demonstrating increased lamp life that meets requirements for commercialization. If successful the proposed research will enhance scientific understanding of the erosion of electrode materials under repeated high-current pulsed cycling. New electrode materials will expand the use of pulsed power and provide better alternatives to thoriated tungsten, which is banned in Europe because of its radioactivity. The primary goal is to enable a new commercial pulsed lamp. The lamp will replace mercury lamps, reducing mercury use and exposure of the public. The lamp also will enable commercial photolytic paint removal, replacing chemical and abrasive techniques that are labor intensive, create dust and debris, and generate toxic byproducts. The photolytic process will provide a lower cost and cleaner method of removing lead paint. This will allow abatement to replace "interim measures" currently in vogue, and support national goals to eliminate childhood lead poisoning. The commercial market for the new lamp encompasses all of UV water treatment and a wide range of paint removal applications.
