Patent application number | Description | Published |
20110097161 | Fluidizable potassium fluorozincate - Fluidizable potassium fluorozincate which is very suitable for dry fluxing applications can be prepared from a diluted potassium base selected from the group consisting of KOH, KHCO | 04-28-2011 |
20110110844 | Method for preparing manganese tetrafluoride - Manganese tetrafluoride is prepared by a reaction between manganese difluoride or manganese trifluoride particles and elemental fluorine. During the reaction, surfaces of the particles are rendered fresh, e.g. by mechanical impact on the particles. Thereby, also agglomeration, sintering or vitrification of the particles is prevented. The impact is not so intensive that the particles would be crushed. | 05-12-2011 |
20110220617 | Anticorrosive flux - Aluminum parts, such as heat exchangers, with improved resistance towards corrosion caused by contact with stationary water or aqueous compositions can be obtained by addition of Li compounds to the flux used for brazing such parts. LiF and especially Li fluoroaluminates are very suitable. Another aspect of the invention concerns fluxes containing Li salts and their use for brazing of aluminum parts. | 09-15-2011 |
20110244220 | Metals parts containing a protective coating - Metal parts, especially parts made from aluminium, aluminium alloys, steel and stainless steel, are described which comprise a coating containing TiOF | 10-06-2011 |
20120315497 | Flux forming an insoluble brazing residue - Aluminum parts, e.g., heat exchangers, with improved resistance towards corrosion caused by contact with stationary water or aqueous compositions such as cooling water can be obtained by addition of Li compounds in specific amounts to the flux used for brazing the parts. LiF and especially Li fluoroaluminates are very suitable. The flux and the Li salt can be dispersed in water or an aqueous composition separately. | 12-13-2012 |
20130037172 | Fine particulate flux - A fine particulate flux, an aqueous flux preparation comprising this flux, a method for the manufacture of a coated part of aluminum, aluminum alloys, steel, copper or titanium using such flux, and a method for brazing parts of aluminum or aluminum alloys to parts of aluminum, aluminum alloys, steel, copper or titanium using such flux. The flux can be obtained by sieving, or it can be obtained by removing solids, e.g., in a cyclone, from the drying gases obtained when wet fluxes are dried, especially after their manufacture. Fine particulate flux increases the viscosity of flux preparations comprising the flux dispersed in water or an aqueous or liquid organic carrier. | 02-14-2013 |
20130108933 | Manufacture of LiPO2F2 and crystalline LiPO2F2 | 05-02-2013 |
20130115522 | Manufacture of LiPO2F2 | 05-09-2013 |
20130129595 | Manufacture of LiPO2F2 from POF3 or PF5 | 05-23-2013 |
