Special liquid neutral environment-friendly chemical cleaning agent for ship pipeline and preparation technology thereof

Abstract

The invention relates to a special chemical cleaning agent for a liquid neutral environment-friendly ship pipeline, the chemical cleaning agent comprises the following components according to the proportion: the components and the weight percentages thereof of the cleaning agent are as follows: 0.8 to 1.2 percent of ammonium chloride, 1 to 4 percent of sodium fluoride, 3 to 7 percent of triethanolamine, 6 to 10 percent of sodium salicylate, 1 to 5 percent of fatty acid amide, 0.1 to 0.4 percent of defoamer, 0 to 12 percent of citric acid and the rest of water. A preparation technology is as follows: the components are mixed and arranged in a reaction kettle for carrying out reaction, detection, filtration and packaging according to the proportion. The neutral cleaning agent has the advantages of neutral, environmental protection, high cleaning efficiency, low cost and safe construction. The chemical cleaning agent is mainly used for the pipeline of a ship stern tube lubricating oil system, the pipeline of a fuel oil daily system of a generator, the pipeline of the fuel oil daily system of a boiler, the pipeline of a high and low temperature freshwater system, the pipeline of a hydraulic system of a deck machinery, the pipeline of the fuel oil daily system of a host and the pipeline of the lubricating oil system of the host, thereby assisting the chemical cleaning of water scale, rust scale and impurities in the pipeline of the boiler and the internal system of the waste gas boiler. The chemical cleaning agent is especially good at the chemical cleaning of various systems of a new built ship before driving the vehicle.

Description

technical field [0001] The invention relates to a special chemical cleaning agent for ship pipelines and a preparation process thereof, belonging to the technical field of chemical cleaning. Background technique [0002] At present, the cleaning of pipelines in shipbuilding and repairing in my country is mainly pickling and oil washing. Commonly used pickling is strong acid cleaning agents such as hydrochloric acid and nitric acid. Strong acid cleaning agents have strong scale dissolving ability, high cleaning efficiency and low cost. It is labor-intensive and time-consuming. It pollutes the environment, is dangerous to both equipment and personnel, and is inconvenient in transportation and storage. Due to the strong corrosiveness of strong acid, many valuable equipment on ships are not suitable for use. Compared with pickling, washing the pipeline with cleaning oil is expensive, and the cleaning time is too long and requires a lot of manpower. Contents of the invention ...
