    • Highly weather and corrosion resistant flexible reflective films for solar energy applications and lighting reflectors are formed by vapor-depositing silver onto a flexible support sheet, e.g., biaxially oriented polyester film and adherently bonding a protective fluorocarbon film, e.g., poly(vinyl fluoride), poly(vinylidine fluoride), or poly(tetrafluoroethylene), to the surface of the silver distal to the flexible support sheet with a layer of adhesive. Fluorocarbon film is highly optically transmissive to visible, ultraviolet, and/or near infra-red light between about 300-2,500 nanometers, stable to ultraviolet light, impervious to moisture, non-hygroscopic, scratch resistant, and easy to keep clean. The adhesive is highly optically transmissive to light between about 300-2,500 nanometers and stable to ultraviolet light. Chemical corrosion inhibitors and UV absorbers incorporated into the flexible reflective film can increase its resistance to corrosion and degradation by ultraviolet light.
    • 用于太阳能应用和照明反射器的高度耐候和耐腐蚀的柔性反射膜通过将银气相沉积到柔性支撑片材上形成,所述柔性支撑片材例如为双轴取向的聚酯膜,并且粘合地粘合保护性氟碳膜,例如聚(氟乙烯) 聚(偏氟乙烯氟化物)或聚(四氟乙烯),以一层粘合剂的方式在柔性支撑片的远侧的银的表面上。 氟碳膜对于约300-2,500纳米之间的可见光,紫外线和/或近红外光具有高度透光性,对紫外线稳定,不透湿,不吸湿,耐划伤,易于保持清洁。 粘合剂对于约300-2,500纳米之间的光具有高度透光性,并且对紫外光是稳定的。 结合到柔性反射膜中的化学腐蚀抑制剂和紫外线吸收剂可以通过紫外线增加其对腐蚀和降解的抵抗力。

    • A wiper assembly is provided for cleaning the reactor tubes of an ultraviolet-light reactor. The wiper assembly is positioned inside a reactor chamber of the ultraviolet-light reactor. The wiper assembly includes a wiper that has a circular opening sufficiently large to accommodate a reactor tube. A wiper blade is formed on the wiper circumferential of the opening and being deflected such that when the reactor tube is positioned through the opening, the blade engages the outer surface of the reactor tube. The wiper is formed of a plastic material. The wiper is connected to a platform positioned within the reactor chamber. The platform supports the wiper in the reactor chamber such that the reactor tube extends through the opening in the wiper. According to one aspect of the invention, at least one rod is connected to the platform. The rod extends out of the reactor chamber. The rod can be moved from outside the reactor chamber for mechanically reciprocating the platform along the length of the reactor tube in the chamber, whereby, the wiper blade slides along the outer surface of the reactor tube to wipe off at least some of the fouling that may have accumulated on the outer surface of the reactor tube. According to another aspect of the invention, the platform is supported by a plurality of floats to move with the fluid level in the reactor chamber.
    • 提供了用于清洁紫外光反应堆的反应器管的刮水器组件。 刮水器组件位于紫外光反应堆的反应室内。 刮水器组件包括具有足够大的圆形开口以容纳反应器管的刮水器。 刮水器叶片形成在开口的擦拭器圆周上并被偏转,使得当反应器管通过开口定位时,叶片接合反应器管的外表面。 擦拭器由塑料材料形成。 刮水器连接到位于反应器室内的平台上。 平台支撑反应器室中的刮水器,使得反应器管延伸穿过刮水器中的开口。 根据本发明的一个方面,至少一个杆连接到平台。 杆延伸出反应室。 杆可以从反应器室的外部移动,用于沿着室中的反应器管的长度使平台机械地往复移动,由此,刮水片沿着反应器管的外表面滑动以擦除至少一些污垢, 可能积聚在反应器管的外表面上。 根据本发明的另一方面,平台由多个浮子支撑,以随着反应器室中的液面移动。
