Problems solved by technology

However, the process of this cleaning process is more complicated, the process is cumbersome, and requires a high degree of cleaning technology and professionals. At the same time, strong acid substances such as hydrochloric acid are used for pickling, which is not only toxic but also produces serious gas, which is extremely harmful to human body and environment. large, high risk
[0007] In addition, in order to ensure the surface quality of cleaning and passivation, a higher cleaning temperature is often required, which will generate acid mist during the cleaning process, and will also cause waste of energy and water resources, as well as environmental pollution, which is not conducive to The development of the national economy and the protection of the environment

Embodiment 2

[0053] Embodiment 2 The example of cleaning pipelines in a circular manner

[0054] In a new chemical plant in a factory, the pipes of the plant were cleaned before being put into operation. The dirt in the pipes was mainly anti-rust grease, floating rust and welding slag.

[0055] Pipeline volume: 25m 3 Material: carbon steel, stainless steel

[0056] Scaling situation: Grease and rust are attached to the pipe wall, and there is a small amount of welding slag at the bottom.

Embodiment 3

[0066] Embodiment 3 The example of cleaning the storage tank by spraying

[0067] A company built a new storage tank for organic chemical raw materials. Because the raw materials contained in it have high requirements on the cleanliness of the container, and the inner surface of the new tank has a certain amount of floating rust, a small amount of welding slag and other impurities are also produced during the installation process. It meets the requirements of use, and the three-in-one cleaning agent of the present invention is used to spray and clean the storage tank before use.

Abstract

The invention provides a cleaning agent for oil removing, rust cleaning and rust-proofing, which comprises inorganic acids, zinc salt, chelating agent, inorganic salt addition agent, surface active agent, defoaming agent and water.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a cleaning agent having triple effects of oil removal, rust removal and rust prevention. Background technique [0002] Scaling of industrial equipment leads to energy waste and low efficiency. The installations of domestic large-scale petrochemical, petroleum, offshore oil, power station, metallurgy and other enterprises, the maintenance and expansion of in-service equipment need to be cleaned to make them work normally and efficiently. [0003] Domestic carbon steel industrial equipment, such as pipelines, towers, containers, heat exchangers, heating furnaces, sealed cabins, etc., or complete sets of industrial equipment, must be degreased, descaled, derusted and blunt before commissioning and during maintenance. chemical cleaning treatment such as chemical cleaning; in the mechanical processing manufacturing industry, in order to ensure the quality of the paint film or paint-plastic film lay...
