Problems solved by technology

However, the degreasing speed of these degreasing cleaning agents is very slow, and it is generally necessary to soak the metal in the degreasing cleaning agent solution for a long time—usually more than 5 minutes, and a higher temperature is required
Therefore, the efficiency is very low, the effect of cleaning and degreasing is not good, the cost is high, and the subsequent surface processing quality is affected
In addition, there is another kind of wax-removing water or degreasing agent commonly used in the market. These wax-removing water or degreasing agents generally contain ammonia nitrogen and phosphate, which cause great pollution, high waste water treatment costs, and use temperatures as high as 85 ~92 degrees, high energy consumption

Abstract

The invention belongs to the technical field of cleaning agents, and particularly relates to a nitrogen-free phosphorus-free oil-removing wax-removing cleaning agent. The nitrogen-free phosphorus-freeoil-removing wax-removing cleaning agent comprises the following ingredients, in parts by weight, of 0.1-10 parts of surfactants, 0.01-25 parts of dispersing agents, 0.1-10 parts of regulating agentsand 50-75 parts of water. The nitrogen-free phosphorus-free oil-removing wax-removing cleaning agent is a concentrated weakly alkaline liquid environment-friendly cleaning agent free of ammonia nitrogen and phosphate, by means of the cleaning agent, oil stains can be easily rinsed from the surface of metal, wax is polished, polishing paste on the surface of a workpiece can be effectively washed away without causing adverse effects on the surface of the polished workpiece, and a good cleaning effect can be achieved by raising the temperature or increasing the concentration.

Description

technical field [0001] The invention belongs to the technical field of cleaning agents, and more specifically, the invention relates to a nitrogen-free, non-phosphorous, oil- and wax-removing cleaning agent. Background technique [0002] Cleaning and degreasing processes are required in various fields of production and industrial processing, such as surfaces such as metal, glass, enamel, plastic and paint. The properties of various surfaces to be cleaned are very different, but the purpose of cleaning is the same, all of which are to remove grease, organic residues, pigment dirt and its covering layer and oxidized substances, and use alkaline solution to saponify grease to remove Saponified oils; use the emulsification of surfactants to remove non-saponified oils. All vegetable oils and animal fats are saponified oils, and all mineral oils composed of hydrocarbon mixtures, such as gasoline, petrolatum, paraffin, various lubricating oils, etc., are non-saponified oils.
