Industrial salt is not edible salt. The ingredient of edible salt is sodium chloride. It can not only be used as a condiment for cooking in daily life, but also can have many functions in ordinary life. Many people know that industrial salt can be obtained by drying in sea water, but many people are not sure about the specific steps of sun drying of industrial salt, so friends who want to know how to sun dry industrial salt, please Follow the editor to continue to understand: 1. Dig the seawater storage pond, hit the high tide, the seawater enters the pond, and it naturally encounters the sun and begins to condense. 2. Waterwheels Waterwheels pour seawater into a piece of agglomeration field where the foundation is not high with mud, and the level is higher than that of the storage pond, and then from two to three, and so on. The agglomeration field is lower than the other, and the sea water is left little by little. 3. Since the seawater is continuously evaporated by the sun during the driving process, when the concentrated seawater flows into a raw salt field, the seawater will gradually solidify into salt particles. If the brine concentration is insufficient, add salt seeds to speed up the knot. Industrial salt has a wide range of industrial uses and is one of the basic raw materials of the chemical industry, known as the "mother of the chemical industry". Hydrochloric acid, caustic soda, soda ash, ammonium chloride, chlorine, etc. in the main products of the basic chemical industry are mainly produced with industrial salt as raw materials. The main components of industrial salt are sodium chloride and sodium nitrite. In daily life, many people cannot distinguish between edible salt and refined industrial salt. Refined industrial salt is a toxic substance. Accidental consumption of industrial salt will cause poisoning events and cause damage to the human body. Certain damage, eating too much can even cause serious harm to the body's organs, so everyone must distinguish clearly between edible salt and industrial salt.

Everyone knows that industrial salt is inedible, so some people ask, what is industrial salt for? What is the use? To talk about the use of industrial salt, we must first mention its nickname - "the mother of the chemical industry". The main products of the basic chemical industry, such as hydrochloric acid, caustic soda, soda ash, ammonium chloride, chlorine, etc., are mainly made of industrial salt as raw materials produced. Not only that, but industrial salt has great uses in different industries. 1. Application in chemical industry The chemical industry is the basic industry of the national economy. Three acids (sulfuric acid, hydrochloric acid, nitric acid) and two alkalis (soda ash, caustic soda) are the basic chemical industries, and among them, hydrochloric acid, soda ash, and caustic soda are produced with salt as the main raw material, and each 1 ton of soda ash or caustic soda consumes 1.2 ~1.4 tons of raw salt, in industrialized developed countries, chemical salt generally accounts for more than 90% of the total salt consumption. 2. Application in dye industry The raw materials commonly used in the dye industry such as caustic soda, soda ash and chlorine are directly produced from salt, while hydrochloric acid, sodium sulfide, hydrosulfite, etc. are chemical products obtained by deep processing of salt; in addition, a large amount of salt is directly consumed. Therefore, the dye industry is one of the industries that is very closely related to the salt industry in addition to the chlor-alkali industry. And almost every step in the dye production process consumes a certain amount of salt. 3. Application in metallurgical industry Industrial salt is used as chlorinated roasting agent and quenching agent in metallurgical industry, and also as desulfurizing agent and clarifying agent for processing metal ores. Immersion of steel products and steel rolled products in a salt solution can harden the surface and remove the oxide film. Salt chemical products are used in pickling of strip steel and stainless steel, baking auxiliaries such as aluminum smelting and electrolysis of sodium metal, as well as refractory materials in smelting. 4. Application in tanning industry A large amount of cortex is required. In the process of storage and transportation, in order to prevent or inhibit the erosion of microorganisms, the raw leather needs to undergo antiseptic treatment, so as not to reduce the quality of the leather. The commonly used anti-corrosion method in the tanning industry is the benefit of salt drying. At the same time, it is used as a commonly used catalyst in carburizing chemical heat treatment. In the process of heat treatment, quenching with salt water can also obtain ideal results. 5. Application in petroleum industry In the process of oil well drilling, in order to protect the integrity of the rock salt layer core, it is necessary to add salt to the mud as a stabilizer, and use the salt chemical product barium sulfate to increase the weight of the drilling mud and act as a regulator. When refining petroleum, in order to remove the water mist in gasoline, salt is used as a dehydrating agent. In the kerosene refining process, the salt is used as a filter layer to remove the impurities. There are also many salt chemical products that are also widely used in the petroleum industry. The above is the relevant introduction about the use of industrial salt, have you understood it? Hope to help you!

The role of industrial salt in many industries should not be underestimated. Although everyone roughly knows that it has a very wide range of uses, but does not know its specific application in various fields, then, in normal life, what fields can industrial salt be used in? ? Let's take a look at the application scope of industrial salt. 1. Wooden furniture may have moths after a long time of use. At this time, rubbing the surface of the furniture with salt water can effectively prevent moths. Moreover, the broom at home will shed the seedlings after being used for a long time. You can soak the newly bought broom in salt water for a while, and then use it after drying to prevent hair loss. 2. Washing rattan and bamboo utensils with salt water will become more durable. If there are black spots on the copper utensils at home that cannot be wiped off, you can easily wash them off with salt. Like the weeds in the house grow quickly, you can sprinkle some industrial salt on the weeds, and the effect will be seen after 3 or 4 days. 3. Application in building materials industry, soda ash made from salt is the main raw material for producing glass. In addition, in order to eliminate the bubbles in the glass melt when melting glass, a certain amount of fining agent needs to be added, and salt is also a commonly used fining agent component, and the amount of salt is about 1% of the glass melt. Common stoneware, terracotta tiles and jars require salt as a glazing agent. The salt consumption per cubic meter of pottery is 0.5 to 3 kg. In order to improve the performance of enamel enamel glaze, some enamel additives should be added before enamel coating. Salt is a kind of enamel additive, which is used for surface glaze to increase the strength of powder blanks and improve the ability to resist scratches and abrasions after making enamels. . In every 100 kg of glaze paste, the higher amount of salt is 0.3 kg. 4. Not only the common raw materials of dye industry such as caustic soda, soda ash and chlorine gas are directly produced from industrial salt, but also hydrochloric acid is also a chemical product obtained by deep processing of salt. In addition to this, almost every step in the dye production process consumes a certain amount of salt. 5. Application in the machinery industry, in casting, salt can be used as an excellent binder for non-ferrous metal and alloy casting sand. At high temperature, salt promotes the softening of the casting core, thereby preventing the occurrence of hot cracks in the casting. Compared with organic binders, salts also generate less harmful gases at high temperatures. The above is the relevant introduction about the scope of application of industrial salt, have you understood it?
