Advantages of calcium chloride in the refrigeration industry
Calcium chloride aqueous solution plays a unique role in the refrigeration system. With its low freezing point, it can effectively lower the operating temperature of the refrigeration system, just like installing a "cooling acceleration engine" on the refrigeration equipment, helping the refrigeration efficiency to soar. Moreover, calcium chloride has very stable chemical properties. It is not easy to evaporate and decompose. It can be circulated in the system for a long time, which greatly reduces the trouble of frequent replenishment and reduces the cost of use. It has become an ideal refrigerant choice in the refrigeration field. However, if it is used in the refrigeration system of metal pipes, it should be noted that it has a certain degree of corrosiveness. Long-term use may require supporting anti-corrosion measures. This is also a place that needs to be weighed compared with other refrigerants.
Advantages of calcium chloride in assisting concrete construction
Adding calcium chloride to concrete has a lot of benefits. It can accelerate the hydration reaction of cement, making the concrete hardening process "run" faster, and the construction period is shortened. Especially in the cold winter construction, the effect is more obvious, and it can effectively prevent the concrete from being frozen. Not only that, it can also "boost" the early strength of concrete and make the stability of the building structure even better. But one thing to note is that if it is added in excess, the strength growth of concrete in the later stage may not be "effective", and it is easy to shrink and crack, so the amount must be accurately controlled and adjusted according to factors such as the construction environment and the type of cement.
Advantages and concerns of calcium chloride in road maintenance
Calcium chloride has a particularly strong hygroscopicity. When used on the road, it can absorb moisture in the air, keep the road surface moist, and "press" the dust down. In the cold winter, it can lower the melting point of ice and snow, like a "snow and ice melting expert", quickly melt the ice and snow on the road, ensure the safety of vehicles and pedestrians, and reduce traffic accidents caused by ice and snow. If the aqueous solution produced after snow melting flows into the soil and water, the high concentration of calcium ions may "make trouble", damage the soil structure, make the soil compacted, and interfere with the calcium metabolism of aquatic organisms, affecting the water ecology. Therefore, when actually using it, you have to pay attention to environmental protection, such as setting up a recycling system to eliminate these hidden dangers as much as possible.
Advantages and considerations of calcium chloride as foliar fertilizer
Calcium chloride has a significant effect when sprayed on crops as foliar fertilizer. It can supplement calcium elements for plants, make plant cell walls more resilient, and improve the ability of crops to resist diseases and lodging. The quality of the fruits produced can also be improved, with fewer physiological diseases and longer shelf life. However, different crops have different calcium absorption efficiencies. If the concentration and time of spraying are not well controlled, it is easy to cause pesticide damage such as leaf burn. Therefore, it is necessary to adjust it according to the crop type and growth stage, and do not use it alone for a long time, otherwise calcium will accumulate in the soil and the balance will be broken.
