Antiseptic film and production process thereof

Abstract

The invention discloses an antiseptic film specialized for cleaning or circularly cleaning a hydraulic pipe and a production process thereof. The antiseptic film comprises the following raw materials in parts by weight: 20-30 parts of triethanolamine, 0.2-0.5 parts of diethylenetriamine, 1-5 parts of boric acid, 2-5 parts of additive and 77-90 parts of water, wherein the additive consists of chloroacetic acid, sodium carbonate and ammonium chloride. The production method of the product comprises the following steps: adding the water into a reaction kettle and adding triethanolamine and the raw materials such as the diethylenetriamine, the boric acid and the additive one by one and sufficiently stirring uniformly for complete dissolution; and accelerating the stirring for reaction for 30 min before stopping the stirring for reaction to obtain the product. The product is directly used for forming the antiseptic film layer by chelation passivation of a clean hydraulic pipe obtained by circularly cleaning the hydraulic pipe. The invention ensures that the service life of the hydraulic pipe subjected to the antisepsis is doubled while ensuring no wastewater discharge, combustion or volatilization, therefore, the antiseptic film is an environment-friendly chemical product.

Description

technical field [0001] The invention relates to an anti-corrosion film and a production process thereof. Background technique [0002] Hydraulic pipelines at home and abroad have been using inorganic acid tank washing process since ancient times. Before installation, hydraulic pipelines are soaked in hydrochloric acid or sulfuric acid in acid tanks, heated and acidified for reaction, derusting, descaling, degreasing, washing, installation, welding, and hydraulic oil circulation. craft. And cause many disadvantages of the inner wall of the hydraulic pipe: 1. Although the rust in the original pipe has been removed, the particles such as welding scars, welding slag, oxides and the like are newly added during welding and remain in the pipe. ② When cleaning with inorganic acid tank, although the rust, calcium and magnesium particles have been cleaned, but no anticorrosion has been carried out, the acid, chloride ion, sulfate group, nitrate group, sulfur dioxide and other oxides ...

AI Technical Summary

Problems solved by technology

③Because there is no circulating cleaning agent after the pipe is welded, welding scars and welding slag are newly added during welding, which promotes the accelerated oxidation of the inner wall of the pipe. These oxidized ions will naturally condense into particles after contacting the hydraulic oil, resulting in blockage and accidents

④Because the inner wall of the hydraulic pipe is not anti-corrosion, the service life of the hydraulic pipe is greatly shortened

⑤Because the hydraulic pipe has a short service life and is easily blocked, it has to be repaired and replaced

⑥Because of cleaning with inorganic hydrochloric acid and sulfuric acid, a large amount of waste acid water is discharged, causing serious environmental pollution

⑦Due to the short service life of the hydraulic pipe, the hydraulic pipe is very easy to produce oxide particles, and the welding scars and slag during welding are not removed, resulting in maintenance, frequent production shutdown, low production efficiency, low output, and high maintenance costs

⑧ Due to maintenance and replacement, a large amount of energy resources are consumed

⑨ Due to the above defects, the cost is high
