Description
Technical Field
The invention relates to an industrial cleaning agent, in particular to a neutral water-based industrial cleaning agent and a preparation method thereof.
Background
Currently, in the category of water-based cleaning agents for the metal industry, cleaning agent products generally fall into three categories: the acidic cleaning agent is prepared by dissolving inorganic acid or organic acid, metal corrosion inhibitor, surfactant and other components in water. The other is alkaline cleaning agent, which is prepared by dissolving components such as strong alkali or alkaline salt and surfactant with water. The other is neutral cleaning agent which does not contain strong acid and strong alkali and is prepared by compounding various surfactants.
The acidic cleaning agent product contains inorganic acid or organic acid components, so that the cleaning product is over-corroded easily due to overlong cleaning time or unclean rinsing with clear water, equipment is corroded by the acidic cleaning agent product after long-term use, the acidic cleaning agent product has large influence on skin, and allergy and red swelling are easy to occur.
The alkaline cleaner product is easy to corrode the skin due to the strong alkali or alkaline salt component, and the damage and the influence on the skin after long-term use are also great.
Although the pH value of the neutral cleaning agent product is 5.5-8.5, the neutral cleaning agent product basically does not corrode cleaning products and equipment, but the cleaning effect is not good as that of an acidic cleaning agent and an alkaline cleaning agent.
