20110030738COPPER ALLOY PLUMBING HARDWARE, SUCH AS VALVES AND TUBE COUPLINGS, AND THE TREATMENT METHOD FOR REDUCING ELUTION OF LEAD - This invention relates to a plumbing device made of a copper alloy containing nickel salt, that includes a valve and a tube coupling having at least a liquid-contacting part washed with a cleaning fluid incorporating therein nitric acid and hydrochloric acid as an inhibitor under conditions of a temperature and a duration permitting effective removal of nickel salt, thereby performing nickel salt-removing treatment and causing the hydrochloric acid to form a coating film on the surface of the liquid-contacting part thereby effectively precluding elution of nickel salt from the surface of the liquid-contacting part in the presence of the coating film, wherein the nitric acid has a concentration c in a range of 0.5 wt %02-10-2011
20100051066COMPOSITION FOR REMOVING RESIDUE FROM WIRING BOARD AND CLEANING METHOD - A composition for removing a residue from a wiring board containing an oxidizing agent and an azole compound and having a pH of from 1 to 7 and a cleaning method of a wiring board for removing a residue after dry etching by using this composition are provided. By using the composition for removing a residue of the present invention, in manufacturing a wiring board, residues remaining after dry etching which are derived from a resist or metals can be effectively removed without corroding titanium or titanium alloys with high corrosiveness. In particular, a semiconductor device using a wiring board containing titanium or titanium alloys can be efficiently manufactured.03-04-2010

20120260938METHOD OF DISSOLVING AND/OR INHIBITING THE DEPOSITION OF SCALE ON A SURFACE OF A SYSTEM - A method of dissolving and/or inhibiting the deposition of scale on a surface of a system comprises the step of bringing the surface of the system into contact with a composition. The composition can comprise from about 3 to about 15 parts by weight of a chelating component. The chelating component is selected from the group of MGDA, NTA, HEDTA, GLDA, EDTA, DTPA, and mixtures thereof. The composition can further comprise from about 3 to about 15 parts by weight of an acidic component, which is different than the chelating component. The composition can further comprise at least about 60 parts by weight of water. Each of the parts by weight ranges above are based on 100 parts by weight of the composition. The composition may further comprise a surfactant component and/or a corrosion inhibitor.10-18-2012

20100326470METHOD FOR CLEANING HVAC SYSTEM AND METHOD AND SYSTEM FOR VERIFYING CLEANING EFFECTIVENESS - A method of cleaning and a system and method of determining the effectiveness of a cleaning process for an HVAC system including a heat exchanger having a coil matrix. The coil matrix includes a plurality of rows of heat exchanging coils in which each adjacent row of coils is offset. The plurality of rows define channels extending through the coil matrix between an upstream side and a downstream side. The heat exchanger cleaning method includes applying a cleaning solution and a wet steam mixture directed into the channels. The effectiveness of the cleaning method is determine by a system and method which measures various operating parameters at the inlet side and outlet side of the heat exchanger both before and after the cleaning process. The system and method calculate a SEER rating using the total amount of heat removed by the HVAC system and the total power usage of the HVAC system.12-30-2010
