Abstract

The invention discloses a high-efficiency scale inhibitor and an application thereof, aiming to solve the problem that the existing scale inhibitors for industrial circulating water are generally complex scale inhibitors mixed with various substances and have a large amount of use. This application proposes for the first time that O,O'-di(hydrocarbyl)dithiophosphate ammonium salt is used as a scale inhibitor, which has the advantages of single component and less dosage, and can effectively overcome the defects of existing composite scale inhibitors . At the same time, the scale inhibitor of the present application has high efficiency, good water solubility, and is easy to use, which can meet the needs of industrial applications. Further, the application claims the application of O, O'-bis(hydrocarbyl) dithiophosphate ammonium salt as a scale inhibitor, which broadens the application field of O, O'-di(hydrocarbyl) dithiophosphate ammonium salt.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to the field of scale inhibitors for water treatment, in particular to a high-efficiency scale inhibitor and its application. This application proposes for the first time the use of O, O'-di(hydrocarbyl)dithiophosphate ammonium salt as a scale inhibitor, which has the advantages of high efficiency, less dosage, good water solubility and simple use. Background technique [0002] Water resources are one of the "three strategic resources" for national economic security and long-term development. my country has a large population, but the per capita water resources are only 1 / 4 of the world average level, and the per capita water shortage is serious. With the rapid development of industry, industrial water consumption has risen sharply. Among them, during the operation of industrial circulating water, along with the continuous evaporation and concentration of water, Ca in the water 2+ ...
