An industrial constant temperature device cooling antifreeze

Abstract

The invention provides an industrial thermostat cooling antifreeze, which comprises the following ingredients in parts by weight: 0.01-0.1 part of defoamer, 0.3-2 part of metal corrosion inhibitor, 0.3-2 part of anti-scaling agent, and 0.1-1 part of buffer part, 30-60 parts of organic solvent; the defoamer is one or both of silicon polydimethylsiloxane and modified silicon polydimethylsiloxane. The cooling antifreeze liquid for industrial constant temperature devices of the invention has the characteristics of good low-temperature defoaming effect, excellent hard water compatibility, metal corrosion inhibition and the like.

Description

technical field [0001] The invention relates to an antifreeze, in particular to a cooling antifreeze used in an industrial constant temperature device, which has the advantages of good low-temperature defoaming, good compatibility with hard water and good metal corrosion inhibition. Background technique [0002] At present, in some industrial installations, the operating temperature of the equipment needs to be maintained at a constant temperature at room temperature of 10-30°C for operation. If the temperature exceeds this constant temperature, the equipment will alarm. Such as bottle blowers in water plants, electric furnaces for cooling circuit method ironmaking, etc. The working temperature of the former is a constant temperature of 10°C, while the latter requires a constant temperature of 25°C. In this way, a conduction medium is needed to take away the heat in time to ensure a constant temperature of the equipment. The conduction medium is cooled by a cooling tower and...

AI Technical Summary

Problems solved by technology

At present, most of the antifreeze fluids used in these devices are ordinary engine antifreeze, but due to the particularity of the working conditions, it is easy to have too much foam, unstable system pressure, and alarms.

These problems are mainly due to the fact that the current engine antifreeze will produce a certain amount of foam. Although the defoamer added suppresses this phenomenon, the defoamers in the engine antifreeze are all high-temperature defoamers. In order to play a better role, the engine operating temperature is about 90°C, and the defoamer can well suppress the generation of foam at this temperature, but for this type of industrial constant temperature device, the operating temperature is basically at room temperature, and the defoaming agent The agent is difficult to work, so there will be problems with excessive foaming
