74% calcium chloride particles have a wide range of uses. In the industrial field, one of them is for snow melting and deicing. In winter, roads are covered with snow and ice, and the calcium chloride particles are scattered, which can reduce the freezing point of ice and snow, make it melt quickly, ensure the smooth flow of roads, and allow vehicles and pedestrians to travel safely. Second, it also has important uses in oil extraction. It can be used as an additive for drilling fluid to help stabilize the well wall, prevent the risk of collapse, and improve the performance of drilling fluid, making mining operations smoother. Furthermore, in construction, it can be used as an accelerant for concrete. In the construction of low temperature environment, the addition of this agent can promote the rapid setting of concrete, improve the efficiency of construction, reduce the construction period, and have no adverse effect on the strength of concrete. It can also be seen in the agricultural field. It can be used as a soil conditioner to adjust the pH of the soil, increase the fertility of the soil, and create a good soil environment for crop growth. At the same time, it can also prevent crop diseases and keep crops thriving. In the food industry, this calcium chloride particle is also used. It can be used as a food additive, such as in the production of soy products, it can be used as a coagulant to solidify soy milk into tofu, and improve the quality and taste of soy products. In summary, 74% calcium chloride particles play an indispensable role in various fields such as industry, petroleum, construction, agriculture, and food, and are an important substance with a wide range of uses.

The storage of 74% calcium chloride granules must follow the iron rule of "moisture-proof, isolation, and environmental control"! Because of its active chemical properties and strong hygroscopicity, the first step is to find a cool, dry, well-ventilated warehouse, completely away from fire and heat sources, and to block direct sunlight - in a high temperature environment, it is not only easy to deliquesce and agglomerate, but also may affect chemical activity. The relative humidity in the warehouse must be suppressed to below 60%. It is best to equip it with a hygrometer for real-time monitoring to provide a "moisture-proof umbrella" for the calcium chloride granules to prevent the properties from changing after moisture absorption. When storing, it is necessary to "clear the territory" with oxidants and acids, and store them separately in different areas. Mixing is like burying a "chemical reaction bomb", especially when encountering acids, which may release dangerous gases. The packaging must be selected from containers with extremely tight sealing. Common woven bags or iron barrels lined with polyethylene film are standard. The seal must be tight to prevent moisture from "taking advantage of the opportunity". Be careful when handling, and do not let the packaging break and leak. Emergency materials such as absorbent cotton and sand should be prepared in the storage area to contain leaks in time. Regularly follow the "first in, first out" principle to check inventory and ensure that each batch of goods is used in the best condition to minimize storage risks!

74% calcium chloride particles are common chemicals, which are active and can react with many chemicals. When meets carbonate, a calcium carbonate precipitate will be formed. If it reacts with sodium carbonate, the chemical equation is: CaCl ² + Na ³ CO = CaCO + 2NaCl. In this reaction, calcium ions combine with carbonate ions to form a white precipitate of calcium carbonate that is insoluble in water. In case of sulfate, calcium sulfate will be formed. Take sodium sulfate as an example, the reaction formula is: CaCl ³ + Na ³ SO = CaSO + 2NaCl. Calcium sulfate is slightly soluble in water, and if the concentration is sufficient, it will also precipitate. With alkali substances, such as sodium hydroxide, although there is no obvious precipitation at room temperature, under certain conditions, hydroxide ions may interact with calcium ions, affecting the existence of calcium chloride in the solution. When encountering active metals, if the metal activity is stronger than calcium, a replacement reaction will occur. If magnesium strips are placed in a calcium chloride solution, magnesium will replace calcium (but this reaction is difficult in practice, due to the high activity of calcium). Reacts with silver salts to form a silver chloride precipitation. For example, when reacting with silver nitrate: CaCl < 2 + 2AgNO < 2 = 2AgCl < 3 + Ca (NO < 3) < 2. Silver chloride is white and insoluble in water and acid precipitation. and some organic compounds, under specific catalysts and conditions, may participate in organic synthesis reactions, altering the structure and properties of organic compounds.

The production process of 74% calcium chloride particles is one of the important issues in chemical manufacturing. The method first takes high-quality calcium sources, mostly calcium-containing minerals such as limestone. Grinding these minerals into fine powder is a preliminary preparation, which increases the reaction area and is conducive to subsequent reactions. Then, add hydrochloric acid to react with it. The reaction is violent, such as boiling soup, calcium and hydrochloric acid blend, resulting in a calcium chloride solution. However, in this solution, impurities still exist and need to be carefully purified. Purification methods, or sedimentation, filtration and other techniques, to remove sediment and insoluble substances; more chemical precipitation methods, to remove magnesium, iron and other impurity ions, so that the solution is pure. The obtained pure calcium chloride solution is then evaporated and concentrated. With the energy of heat, the water is gradually dispersed, and the concentration of the solution is gradually increased to an appropriate concentration, such as the thickness of caramel. The step of recrystallization, or cooling crystallization, or evaporation crystallization, depending on the specific situation. During the crystallization process, calcium chloride molecules are arranged in an orderly manner and gradually form into particles. This particle still contains a little moisture and needs to be dried. By hot air, vacuum drying and other methods, the moisture is removed to obtain 74% calcium chloride particles. The whole process is interconnected and requires fine control to obtain high-quality products.

74% calcium chloride particles are used in various industries, and the use cases are different. In the road maintenance industry, the amount of this particle is quite large every time the road is snowy and icy in winter. Take Baili Highway as an example, after the blizzard, in order to melt ice and snow quickly and ensure smooth driving, about 50-100 kilograms of calcium chloride particles need to be sprinkled per kilometer. If it is measured by a hundred cars, about 5-10 tons of calcium chloride particles are required. Because of its high snow melting efficiency, it can reduce the melting point of ice and snow, speed up ice and snow, and has anti-skid effect to ensure stable vehicle driving. In the construction industry, it is also widely used. For example, in winter construction in the north, calcium chloride particles are often added as an antifreeze agent to prevent the performance of concrete from freezing. Taking the construction project of Qianping as an example, about 5-10 kg of calcium chloride particles are added to each cubic meter of concrete. If the concrete dosage of Qianping project is 2,000 cubic meters, 10-20 tons of calcium chloride particles are required. It can promote concrete condensation and hardening, increase early strength, and resist low temperature invasion. In the oil exploration industry, it is also indispensable. In oil well operations, in order to stabilize the well wall and prevent collapse, calcium chloride solution is often injected. For example, an oil well with a depth of 1,000 meters, injecting calcium chloride solution at one time, if the concentration is appropriate, about 5-8 tons of calcium chloride particles are required. It can reduce the formation water activity, stabilize the shale structure, and keep oil wells in good condition. In the food processing industry, it is also useful. Such as making tofu, as a coagulant, taking a hundred catties of soybean tofu as an example, about 0.2-0.3 kg of calcium chloride particles are required, which can condense soy milk protein into tofu and increase the toughness and texture of tofu. From this perspective, 74% calcium chloride particles are used in different industries, depending on their functions, scenarios, and dosages. They are all of great value in the operation of the industry.
