Surfactant and chelating agent ternary compound descaling agent

Abstract

The invention discloses a surfactant and chelating agent ternary compound descaling agent prepared by mixing the following components in percentage by mass: 20-30% of EDTA (Ethylene Diamine Tetraacetic Acid) disodium salt, 10-40% of DTPA (Diethylenetriaminepentaacetic Acid) and the balance of OP-10. The surfactant and chelating agent ternary compound descaling agent is prepared by mixing OP-10, EDTA disodium salt and DTPA and is favorable in descaling performance; when the surfactant and chelating agent ternary compound descaling agent 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 ternary compound detergent of surfactant and chelating agent. Background technique [0002] Surfactant refers to a substance that has fixed hydrophilic and lipophilic groups, can be aligned on the surface of the solution, and can significantly reduce the surface tension. The molecular structure of surfactants is amphiphilic: one end is a hydrophilic group and the other end is a hydrophobic group; the hydrophilic group is often a polar group, such as carboxylic acid, sulfonic acid, sulfuric acid, amino group or amine Groups and their salts can also be hydroxyl groups, amide groups, ether bonds, etc.; and hydrophobic groups are often non-polar hydrocarbon chains, such as hydrocarbon chains with more than 8 carbon atoms. Surfactants are divided into ionic surfactants and nonionic surfactants. [0003] Surfactants are molecules formed from two distinct particles, one extremely lipophilic and the other extremely hydrophilic. Wh...

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
