Boiler cleaning and lubricating composition,and method of use in hot water system
Abstract
Abstract A BOILER CLEANING AND LUBRICATING COMPOSITION, AND METHOD OF USE IN HOT WATER SYSTEM COMPRISED OF 13.5% POLYPROPYLENE GLYCOL (AVERAGE MOLECULAR WEIGHT 2000), 4.8% TERGITOL NONIONIC XD (POLYALKYLENE GLYCOL ETHER), 3.5% ACRYLIC EMULSION COMPOLYMER (ARCYSOL), 76% WATER, 1.5% SILICONE OIL AND .7 TRIETHANOLAMINE. THE AFORESAID COMPOSITION HAS BEEN FOUND TO BE A REMARKABLE CLEANER AND RUST INHIBITOR FOR USE IN HOT WATER HEATING SYSTEMS BECAUSE IT PROVIDES A PROTECTIVE FILM UPON VARIOUS PARTS OF THE SYSTEM. HOWEVER, THE FILM IS HEAT CONDUCTIVE AND DOES NOT PROVIDE RESISTANCE TO HEAT TRANSFER, AND THIS CREASES THE HEATING CHARACTERISTICS OF THE SYSTEM. THE COMPOSITION OF THE PRESENT INVENTION ALSO PROVIDES LUBRICATING PROPERTIES BY THE PRESENCE OF POLYPROPYLENE GLYCOL AND SILICONE OIL.
