が達成されないことがしばしば生じる。 Generally, water contained in soil freezes quickly when exposed to sub-zero temperatures. To prevent this water from freezing, an antifreeze agent such as common salt or calcium chloride is generally used. Applied to soil etc.
The temperature of the resulting aqueous solution of salts decreases, and even if it reaches its freezing point, it undergoes a supercooling phenomenon for a while, and the temperature decreases without freezing. In other words, although it remains in a liquid state for a while without freezing, it eventually freezes and civil engineering work may have to be stopped. This type of problem can also occur when these salts are used as cryogens, etc., or when they are used in cooled chemical plants, etc., and when these salts are sprayed with a material spreader as an anti-icing agent on road surfaces in winter. Even in this case, if the temperature drops, it will eventually freeze as described above, and the intended purpose will often not be achieved.

究を続け本発明が完成されたのである。 The present invention was made to solve these drawbacks, and as a result of extensive research, it was found that by adding certain copolymers, surfactants, fillers, and thickeners to neutral inorganic salts, It was discovered that there is a freezing delay effect that stabilizes the supercooled state and allows it to remain unfrozen for a long time. Based on this new knowledge, further research was carried out and the present invention was completed.

とができる。 The freezing retardant according to the present invention is formed as described above, and if it is distributed, for example, in soil during the severe cold season, freezing of the soil can be prevented for a long time (for example, at -5°C for 20 hours). As a result, the necessary civil engineering work can be carried out during this time, and construction progresses smoothly even in the coldest months. In addition, if you spray this on the road surface in winter, it will prevent anti-slip materials such as table salt, salt calc, and salt mugs from freezing for a long time, which will provide a great advantage for road traffic. Especially when sand and crushed stone are used in combination, a particularly excellent freezing delay effect can be obtained. Furthermore, in the chemical industry, when these inorganic salts are used together with ice as a refrigerant or cryogen, they can delay freezing and maintain a liquid state for a long period of time, making it possible to prevent freezing of chemical industrial plants. Blockage troubles can be prevented, and processing operations and efficiency can be further improved.
