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

该小型企业创新研究（SBIR）二期项目将进一步研究大电流脉冲操作下电极材料的腐蚀特性，并演示延长新型脉冲灯的使用寿命，使其具有经济实用性。随着使用寿命的增加，新灯可以成为紫外线水处理的行业标准，并实现新的光解漆剥离工艺。用于脉冲功率电极的材料最初是为低峰值电流的连续或交流电流配制的。在第一阶段，钨复合材料用特定的工艺制成，侵蚀的程度是标准电极材料的1 / 16。第二阶段继续研究这种钨复合材料及其制造工艺，以证明低腐蚀，目的是证明延长的灯寿命，满足商业化的要求。如果成功，该研究将加强对反复大电流脉冲循环下电极材料侵蚀的科学理解。新的电极材料将扩大脉冲功率的使用，并提供更好的替代品，以取代钍钨。由于其放射性，钍钨在欧洲被禁止使用。主要目标是使一种新的商业脉冲灯成为可能。该灯将取代汞灯，减少汞的使用和公众接触。这种灯还将实现商业化的光解涂料去除，取代化学和研磨技术，这些技术是劳动密集型的，会产生灰尘和碎片，并产生有毒的副产品。光解工艺将提供一种成本更低、更清洁的去除含铅涂料的方法。这将使减少措施能够取代目前流行的“临时措施”，并支持消除儿童铅中毒的国家目标。新灯的商业市场包括所有的紫外线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.
