Binary compound surfactant

Abstract

The invention discloses a binary compound surfactant. The binary compound surfactant is formed by mixing OP-10 (polyoxyethyleneoctylphenyl-10) with Span 80, wherein a weight ratio of the OP-10 to the Span 80 ranges from (1:4) to (4:1). The binary compound surfactant provided by the invention is formed by mixing the OP-10 with the Span 80, and has the good descaling property; the descaling rate is greatly improved when the binary compound surfactant is applied to descaling; and furthermore, the manufacturing cost is low and the descaling cost is greatly reduced.

Description

technical field [0001] The invention relates to a binary compound surfactant. Background technique [0002] Descaling agent is a chemical preparation that removes scale, dirt and other stains, and is generally composed of multiple components. Industrial descaling agents are mainly used to remove dirt in heat exchange equipment, boilers, etc. [0003] Common types of descaling agents and their characteristics: [0004] (1) Inorganic polyphosphate. This type is the earliest descaling agent used, and its use has been restricted abroad. There are one or more repeated P-O-P bonds in its molecule, which can be divided into chain polyphosphate and cyclic polyphosphate. The disadvantage of inorganic polyphosphate is that it is easy to be hydrolyzed by moisture to form orthophosphate, especially at high temperature and high pH value, and it will react with divalent cations such as Ca2+, Mg2+, etc. to scale. [0005] (2) Organic phosphates. Common organic phosphates include mono...

AI Technical Summary

Problems solved by technology

This kind of descaling agent mainly prevents scale through chelation, so the amount added is large and the cost is high, so its use is limited in industrial processes with large amounts of water
