Problems solved by technology

At present, most of the builders selected are still mainly phosphates, but with the increasing application of water-based cleaning agents, the discharge of phosphorus-containing substances into the environment and causing eutrophic pollution has gradually emerged, and some traditional metal cleaning agents are commonly used The biodegradability of APEO surfactants is slow, and the potential harm of APEO to the environment has been widely studied and demonstrated, and the production and use in the European Union, Japan and other countries are subject to more and more restrictions

Abstract

The invention relates to a normal-temperature phosphorus-free water-based cleaning compound. Each liter of water contains the following components: 0.2-1.5 g of fatty alcohol polyoxyethylene ether, 1.0-3.0 g of iso-tridecanol polyoxyethylene ether, 0.5-3.0 g of fatty alcohol EO / PO polyether, 0.3-2.0 g of 2-sodium 2-ethylhexyl sulfate, 10 g of sodium silicate, 5 g of sodium carbonate, 0.1-0.5 g ofsodium citrate, and 0.2-0.8 g of EDTA2Na. The cleaning compound has rust-protection and corrosion inhibition effect for metal, corrosion and damage are little, and the cleaned cold rolling plate surface is clean and shine.

Description

technical field [0001] The invention belongs to the cleaning agent field and relates to a normal temperature cleaning agent, in particular to a normal temperature phosphorus-free water-based cleaning agent. Background technique [0002] Metal cleaners are mainly used for cleaning in the production of parts. In surface treatment such as coating and electroplating, degreasing is an important process. The degree of degreasing on the surface of metal parts will directly affect the quality of subsequent treatment of workpieces. Water-based metal cleaning agents use water instead of oil, save energy, do not endanger the health of operators, reduce pollution, protect the environment, and have low cleaning costs, and have developed rapidly at home and abroad. At present, most of the builders selected are still based on phosphate, but with the increasing application of water-based cleaning agents, the discharge of phosphorus-containing substances into the environment and causing eutr...
