Sodium chloride, chemical formula NaCl, colorless cubic crystal or fine crystalline powder, salty. The appearance is white crystal, and its source is mainly sea water. Soluble in water, glycerin, slightly soluble in ethanol (alcohol), liquid ammonia; insoluble in concentrated hydrochloric acid. Impure sodium chloride is deliquescent in the air. The stability is better, the aqueous solution is neutral, and the industry generally uses electrolytic saturated sodium chloride solution to produce hydrogen, chlorine and caustic soda (sodium hydroxide) and other chemical products (generally called chlor-alkali industry) can also be used for ore. Smelting (electrolytic melting of sodium chloride crystals to produce active sodium metal), medically used to configure physiological saline, can be used for condiments in life.
Sodium chloride is a white odorless crystalline powder with a melting point of 801 ° C and a boiling point of 1465 ° C. It is slightly soluble in ethanol, propanol and butane. It becomes a plasma after being miscible with propane. It is easily soluble in water. The solubility in water is 35.9g. (room temperature). NaCI is dispersed in alcohol to form a colloid, and its solubility in water is reduced by the presence of hydrogen chloride, and it is hardly soluble in concentrated hydrochloric acid.
Industrial salt is widely used in industry and is one of the most basic raw materials in the chemical industry. It is called "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 from industrial salt.
Industrial salt refers to the original salt. The original salt is divided into lake salt, well salt and sea salt. Because seawater in sea salt dissolves into various elements, the industrial value of sea salt is relatively higher, and the edible value is lower.
The refined salt has a sodium chloride content of about 99%. Like the salt in the house, it has good fluidity and can be shipped from Taian, Jiangsu Huai'an and Hubei Yingcheng. The refined industrial salt content is about 99%, which is the same as the salt in the home. Anti-caking agent, good fluidity, can not agglomerate for a long time; refined industrial salt content of 97% white color, making by-products of magnesium chloride hexahydrate, shape close to powder, no anti-caking agent added, easy to agglomerate after damp The place of delivery is Changyi, Haihua and Binzhou. 99 content does not add anti-caking agent is generally called iodine-free and anti-deterioration industrial salt, customers are generally used to make soft water salt ball, salt factory generally does not sell, it is difficult to ship, profit can stay a little more)
sea salt
After crushing, washing, drying, color selection, the color is translucent, mainly for hot compress, can also be used as bath salt (such as foot bath), and can be eaten as sea salt.

Feed salt
can be shipped from Yangkou, Haihua, Tai'an and Haixing. The
price of qualified feed salt is slightly higher. If the farmer uses it himself, he can recommend small white salt.

The salt products also have yellow powder salt for aquarium, sea crystal for aquaculture, and are shipped from Laizhou by
-products such as
Hebei, Zibo, Shouguang and Heze. They are mainly used for cement grinding aids, printing and dyeing, and the size of 80
seas. Crystal
powder, simulating seawater environment, mainly used in aquatic products market, improving the survival rate of aquatic products. The
national standard GB5462-2003 is
specially proposed, as well as low sodium salt and
low sodium salt, which is a healthy salt. Based on the iodized salt, a certain amount of potassium chloride (about 30%) is added. Compared with common sodium salt, it has low sodium (70% sodium chloride), and is rich in potassium (about 30% potassium chloride), which helps the body to balance sodium and potassium, lowers blood pressure, and has a risk of cardiovascular disease.
Low sodium salt function: alkali Salt does not reduce salt, help the body balance sodium and potassium, reduce high blood pressure, cardiovascular disease risk
Uses: export kimchi
