    • PURPOSE: Provided is hot water for a boiler, which prevents the freezing and break of pipes during the winter and prevents the corrosion of an internal combustion engine, the pipes, and connection parts of the pipes, therefore, maximizes the circulation of the hot water. CONSTITUTION: The hot water is produced by a process comprising the steps of: refining each of glycol and water in a vacuum-state filtering tank; synthesizing and blending by adding a corrosion-resistant agent, a defoaming agent, and a colorant; heating the synthesized and blended glycol and water; precipitating the heated glycol and water at an ordinary temperature for 48 hours in a non-vibration precipitating tank; storing at an ordinary temperature in a vacuum-state storing tank; blending 85-90% of the refined glycol and 10-15% of the refined water; refining the mixture in a vacuum-state filtering tank; filling containers with the refined mixture in a vacuum filling tank. The glycol is selected from ethylene glycol, polyethylene glycol, propylene glycol, diethylene glycol, triethylene glycol, and etc.

    • The present invention relates to a metal corrosion inhibitor composition and a pickling solution using same, in which metal can obtain a beautiful surface because the metal is not partially melted or corroded when the surface of the metal is subject to a pickling process. The metal corrosion inhibitor composition according to the present invention includes heterocyclic aromatic nitrogen compounds, epichlorohydrin, and an organic compound expressed as RYX. In the RXY, R is C1-C12, Y is H2-H24, and X is a hydroxyl group. The bond between at least two carbons is one of a single bond, a double bond, and a triple bond.
