Abstract

The invention provides a PBTC anti-scaling disperser, which comprises 2-phosphonobutane-1,2,4-tricarboxylic acid, acroleic acid-acrylate-petroleum sulfonate copolymer, zinc chloride, benzotrizaole and water, which can be operated under high pH, and can be used for forming a layer of thin and compact anti-corrosive film on the surface of metals, thus effectively inhibiting metallic corrosion.

Description

Technical field: [0001] The invention relates to a scale inhibitor dispersant, in particular to a phosphonic acid efficient scale inhibitor dispersant used in industrial circulating water systems. Background technique: [0002] Since environmental protection and sustainable development became my country's basic development strategy in 1995, the research and development of environmentally friendly water treatment agents has become one of the hot spots and important development directions of industrial water treatment research. Most of the water treatment agents in the prior art are synthetic polymers, although their toxicity is low, but they are not easily biodegradable, and may soon face severe challenges of environmental restrictions. Invention content: [0003] The technical problem to be solved by the present invention is: since most of the water treatment agents in the prior art are synthetic polymers, although their toxicity is low, they are not easily biodegradable, ...
