Problems solved by technology

This type of cleaning agent has a relatively satisfactory cleaning effect on the oil stain on the surface of the workpiece, but its cleaning effect on the dust on the metal surface is not satisfactory
However, most of the cleaning agents with good ash removal effect on the market are acidic or weakly acidic. They will be slightly corrosive to acid-resistant metal workpieces such as magnesium alloys and aluminum alloys under heating conditions, and cannot achieve simultaneous removal. The purpose of oil ash removal, so higher requirements are placed on the cleaning ability of the cleaning agent

Abstract

The invention provides a corrosion-free cleaning agent which can be used under heating condition (60-75 DEG C), can remove oil and dust and has fast cleaning speed. The cleaning agent comprises the following components in parts by weight: 10-25 parts of organic phosphate, 5-20 parts of sodium polyacrylate, 15-30 parts of sodium polycarboxylic acid, 5-20 parts of surfactants, 10-25 parts of settling agents, and 15-35 parts of water. The corrosion-free cleaning agent innovatively utilizes the organic dispersants and the settling agents in combination with the surfactants such as isomeric alcoholpolyoxyethylene ether with high permeability and in cooperataion with the chelating property of organic phosphate, so that the cleaning agent maintains excellent dust removal effect and also has an extremely good oil removal effect. The corrosion-free cleaning agent for removing oil and dust has obviously stronger oil and dust removing effect than the conventional cleaning agent, and is nearly neutral and has no corrosion to metal products such as a magnesium alloy, so that the corrosion-free cleaning agent has very high practical application value.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment and relates to a metal surface cleaning agent, in particular to a metal surface cleaning agent capable of removing oil and dust and having a fast cleaning speed. Background technique [0002] Many metal products use drawing oil, cutting fluid or liquid wax in the forming or polishing process. After the above-mentioned process, a large amount of grease, dust, wax scale and other dirt will remain on the surface of the metal workpiece. At present, cleaning agents combined with ultrasonic cleaning are commonly used in the market to remove oil first and then clean dust. Although the cleaning effect of the two-stage process is good, it takes a long time and cannot meet the needs of enterprises to improve efficiency. At present, in order to increase production capacity, many enterprises hope to use only one cleaning agent to clean the oil and dust on the surface of the workpiece. [0003...
