Soda ash

1. Introduction to pure alkali

Sodium carbonate (NA2CO3), molecular weight 105.99. The purity of chemicals is more than 99.5%(mass score). Pure alkali is also known as soda, alkaline ash, alkali noodles or washing alkali. The classification is salt and does not belong to alkali. Skin -alkali is an important basic chemical raw material. It has the reputation of "mother of chemical industry". It is widely used in many fields such as building materials, chemical, metallurgy, textiles, food, national defense, and medicine, and occupy a very important position in the national economy.

Depending on the use, pure alkali can be divided into industrial pure alkali and consumption soda. The main products of pure alkali industry can be divided into light alkali and severity according to different density. The chemical composition is sodium carbonate, but the physical form is different. Light -alkali is mainly used in the daily glass industry, detergent and food industry. Severe alkali is obtained by light or squeezing by light alkali through water or squeezing method. It is mainly used to produce flat glass.

The production processes of pure alkali are mainly natural alkali, ammonia and alkali method. The production capacity of the three production processes accounted for 6%, 45%, and 49%, respectively. The upstream of natural alkali alkali is natural alkali ore. The upstream of amino -alkaline -based alkali is the original salt and limestone. Alkaline -made fuel is mainly power coal, and individual enterprises also use natural gas.

In the field of downstream applications in China, 96%of the soda -produced soda belong to industrial pure alkali. Glass is the main downstream of industrial pure alkali, accounting for 52%of the demand for pure alkali. The second is soap and detergent, which accounts for 13%of the demand for pure alkali. Inorganic chemicals accounted for 12%of pure alkali demand, and the first three accounted for 77%of the demand for pure alkali.

Status status of pure alkali market

2. Skin -alkali production situation

Global pantylinum capacity is more concentrated, and the total production capacity of China, North America and Western Europe accounts for about 80%of the national capacity. From the perspective of the current global capacity distribution, China has become an absolute dominant country for pure alkali. As of the end of 2018, China's citromey capacity has reached 29.59 million tons, and global production capacity has reached 70.33 million tons, accounting for 48%of the world. my country's pure alkali production is mainly concentrated in East China, Central China and Northwest.

3. the needs of pure alkali

China, Western Europe, North America, and Southeast Asia are the main consumption places for pure alkali, accounting for 79%of global consumption. China is the world's largest consumer consumer. In recent years, China's demand has increased rapidly. The main demand for pure alkali in my country has been in the main production areas of domestic glass in South China, North China and East China.

In addition to the domestic market, my country is also a net exporter of pure alkali.
