Steel surface cleaning agent and application thereof

Abstract

The invention belongs to the field of detergents, and provides a steel surface cleaning agent. Quaternary ammonium hydroxide is adopted as an active ingredient, and the general formula of the quaternary ammonium hydroxide is as shown in the specification. The quaternary ammonium hydroxide is taken as the steel surface cleaning agent, and can be cleaned at normal temperature, the cleaning time is short, and an excellent cleaning effect can be achieved, to be specific, effluent is clear and transparent. Steel components, equipments and pipelines which are newly put into use or shelved for a long period of time can be thoroughly cleaned.

Description

technical field [0001] The invention belongs to the field of detergents, and in particular relates to a washing composition containing a quaternary ammonium base and an application method thereof. Background technique [0002] Steel products are often used in the process of processing, storage and transportation, which are based on mineral or animal and vegetable oils, plus various organic additives or inorganic substances. This is the main source of oil pollution on the steel surface. The existence of oil pollution will affect pickling. The quality of rust removal and phosphating affects the drying performance of the coating and reduces the adhesion of the coating. Therefore, the equipment must be cleaned on the surface of steel parts before use. Steel equipment used in the fields of organic chemical and food production will also generate oil stains on the surface. If it is not cleaned, it will affect product quality. [0003] The difficulty of removing oil stains is rela...

AI Technical Summary

Problems solved by technology

Steel equipment is used in the fields of organic chemical industry and food production, and oil stains will also be generated on the surface. If it is not cleaned, it will affect product quality

[0003] The difficulty of removing oil stains is related to the composition and physical and chemical properties of oil stains. Animal and vegetable oils can be saponified and can be removed by saponification, emulsification and dissolution. Oil stains with higher viscosity and higher melting point are more difficult to clean. Oil stains with stronger polarity are also difficult to clean due to their strong adhesion to the metal surface. The oxidative dry film formed by long-term storage or high-temperature baking is difficult to clean. , lubricants with solid particles, grinding, cleaning of polishing paste is also very difficult

[0004] At present, most of the degreasing powder used for cleaning and degreasing steel surfaces is made of phosphorus-containing raw materials, and chemical degreasing is required at medium temperature. , consumes energy

There is no report on the application of quaternary ammonium base as cleaning agent
