[0036]After mixing and dissolving the quantitative ethylene glycol, hydrogen phosphate, glycopritoline, sodium nitrite, phenyl triazorazole, and deodorded water, add the nails of the nails for coloring and stir until evenly.

[0037] 2. Mix with 1: 4 with the prepaid ethylene glycol -freezing solution with 1: 4.The corrosion rate of the six metal slices is: Copper 2.76 × 10 -3 mm / a, solder 3.01 × 10 -3 mm / a, brass 2.79 × 10 -3 mm / a, carbon steel 0.72 × 10 -3 mm / a, cast iron 2.69 × 10 -3 mm / a, cast aluminum 8.94 × 10 -3 mm / a.After the experiment, the color of each metal piece has not changed, and there is no attachment. The total number of bacteria of the antifreeze after the experiment is 10 1 One / ml.

[0038] Example 3

Embodiment 3

[0040] Formula: ethylene glycol 960g, hydrogen phosphate di potassium 25g, isopedazoleol 0.4g, sodium nitrite 1g, azole compound (benzazole) 0.02g, water -soluble dye (Asian metal blue) 0.1g, de -ion water water13.48g.

[0041] After mixing and dissolving the quantitative ethylene glycol, hydrogen phosphate, glycopritoline, sodium nitrite, phenyl triazorazole, and deodorded water, add the nails of the nails for coloring and stir until evenly.

[0042] 2. Mix with 1: 3 with the prepaid ethylene glycol refrigeration liquid with 1: 3.The corrosion rate of the six metal slices is: Copper 2.55 × 10 -3 mm / a, solder 2.86 × 10 -3 mm / a, brass 2.57 × 10 -3 mm / a, carbon steel 0.67 × 10 -3 mm / a, cast iron 2.47 × 10 -3 mm / a, cast aluminum 8.01 × 10 -3 mm / a.After the experiment, the color of each metal piece has not changed, and there is no attachment.

Abstract

The present invention discloses an inhibition ethanediol antifreezing fluid, comprising the following components, by mass percentages: 94% to 99% of ethanediol compound, 0.5% to 5% of sylvite, 0.001% to 1% of azole compound and 0.001% to 0.015% of water-soluble dye. By adding sylvite into the antifreezing fluid, the invention enables the antifreezing fluid to have high concentration of potassium ion, improves the usefulness of bacteriostasis and antiscale of the antifreezing fluid effectively; and by the optimization combination with other constituents, the antifreezing fluid provided by the invention achieves the effects of anticorrosion, antiscale and bacteriostasis throughout the year; prolongs the service life of system is substantially and saves the equipment cost and the operation cost. The antifreezing fluid also achieves the advantages of stable performance, nontoxicity, innocuousness, low cost and wide usage temperature scope; can be used at the temperature from -50 DEG C to 120 DEG C, is antifreeze in winter and anti-boil in summer.

Description

Technical field [0001] The invention is the field of anti -freezing liquid, which involves a kind of glycolic inhibitory antifreeze. Background technique [0002] At present, almost all buildings such as residential, hotels, hotels, shops, and office buildings in the south or north are installed with split air conditioners or central air conditioners.Especially in the southern region, the use of air -conditioning to cool down all year round is very long, and the use of air conditioners to cool down requires a lot of energy.As one of the important energy -saving methods of the new century, ice storage cooling is a new technology that benefits human beings and has broad development prospects, and has good social effects and economic benefits.Today, the world's energy and environmental protection are increasingly important, ice storage cooling will be reclaimed as my country's power migration peak, increasing the power load rate of power grids, improving the comprehensive benefits ...
