摘要： A moisture treatment and leak sealant product for a vapor-compression system has two separate components. One of the components includes a viscosity modifying additive, excluding oil compounds, to more closely match a viscosity of the product to that of lubricating oil in the system and a drying agent to remove moisture from the system. The second of the components includes a silane leak sealant and also the viscosity modifying additive.

摘要： Methods and systems for cleaning, coating and sealing leaks in existing pipes made of nonmetal materials selected from a nonmetal material selected from at least one of plastics, PVC (polyvinyl chloride), composite materials, or polybutylene, in a single operation. A piping system can be cleaned in one pass by dry particulates forced and pulled by air throughout the piping system by a generator and a vacuum. Pipes with nonmetal fittings or with metal fittings or pipes with a combination of metal and nonmetal fittings can be protected from wear by water erosion and rupturing, extending the life of pipes made of nonmetal materials selected from at least one of plastics, PVC (polyvinyl chloride), composite materials, or polybutylene. Coatings can be applied to pipes having diameters up to approximately 6″. Leak sealants of at least approximately 4 mils thick can cover insides of pipes, and can include novel mixtures of fillers and epoxy materials, and viscosity levels. A positive pressure can be maintained within the nonmetal pipes during applications. Piping systems can be returned to service within approximately 96 hours.
