Abstract

The invention discloses an EDTA (Ethylene Diamine Tetraacetic Acid) disodium salt compound surfactant prepared by mixing OP-10 and EDTA disodium salt, wherein the ratio of OP-10 to EDTA disodium salt is 2:5 to 4:3 according to the mass. The EDTA disodium salt compound surfactant is prepared by mixing OP-10 and EDTA disodium salt and is favorable in descaling performance; when EDTA disodium salt compound surfactant is used for descaling, the descaling rate is greatly increased, and the manufacturing cost is low, so that the descaling cost is greatly reduced.

Description

technical field [0001] The invention relates to a compound surfactant of EDTA disodium salt. 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 phosphat...
