Problems solved by technology

At present, the cleaning and degreasing agents applied to steel strips in the prior art must be used at relatively high temperatures to achieve better results. General conventional cleaning agents need to be accompanied by a heating process. This heating process is cumbersome and It consumes more energy, requires higher requirements for existing equipment conditions, and is likely to cause serious pollution to the air environment
Moreover, such conventional cleaning agents will generate a large number of air bubbles during use, which will not only take away part of the degreasing agent, but also cause waste, thereby making the working environment on site worse

Abstract

The invention relates to the technical field of cleaning agents for metal products and particularly relates to a special low-temperature cleaning agent for strip steel. The low-temperature cleaning agent comprises the following components in parts by weight: 10-16 parts of mixed alkaline solution, 2-5 parts of aqueous hydrogen peroxide solution, 2-4 parts of surfactant solution, 0.1-0.22 part of a complexing assistant, 1-2 parts of polyoxypropylene glycerol ether and 1-3 parts of antibacterial agent. Compared with the prior art, the special low-temperature cleaning agent for strip steel can be used under a low temperature condition and is few in foam. The formula provided by the invention is mild in using condition, so that the cleaning agent is particularly suitable for surface treatment of stripe steel at a certain speed and is further suitable for surface treatment of large common metal products. The cleaning agent is low in cost, wide in source of raw materials and suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of a cleaning agent for metal products, in particular to a special low-temperature cleaning agent for strip steel. Background technique [0002] The long-term practical results have proved that the cleaning and degreasing process of the strip surface is an important link that affects the product quality in the coating and plating production line on the surface of metal products. Fully spread and adhere, in severe cases, it will cause the coating layer on the surface of the metal product to peel or fall off. [0003] Strip cleaning and degreasing agents in the prior art generally include alkaline solution, antibacterial agent and chelating agent. The strip steel cleaning and degreasing process is to use the active ingredients in this type of strip steel cleaning and degreasing agent to reduce the adhesion of oil on the surface of metal products, and to convert the oil into soap or form an emulsified state th...
