Light soda ash is an important inorganic chemical raw material, which is widely used in glass, soap, detergent, food, medicine, metallurgy and other fields. In the field of chemical production raw materials, there are many upstream and downstream related products of light soda ash, some of which will be described in detail below.

upstream products:

1. salt: the production of light soda ash mainly adopts ammonia alkali method and combined alkali making method, both of which need to use salt as raw material. Therefore, salt is an important upstream product of light soda ash.

2. Limestone: Limestone is also one of the necessary raw materials in the combined alkali making process, which is used to provide calcium ions for production.

3. Coal: In the production process, coal is used as fuel to provide the necessary heat energy, so coal is also one of the upstream products of light soda ash.

downstream products:

1. Glass: Lightweight soda ash is one of the main raw materials for glass production, accounting for about 20%-30% of glass production costs. In glass production, light soda ash is melted with quartz sand, limestone and other raw materials to form a glass liquid, which is made into glass products after molding, annealing and other processes.

2. Soap and detergent: Light soda ash can be used to produce soap and detergent. Its main component is sodium carbonate, which has good decontamination ability.

3. Food additives: Light soda ash can be used as food additives to adjust the pH of food, improve food taste and preservation performance.

4. Chemical raw materials: Light soda ash can also be used to produce many chemical raw materials, such as sodium bicarbonate, sodium hydroxide, hydrogen peroxide, etc.

In short, as an important inorganic chemical raw material, light soda ash has a wide range of upstream and downstream related products, involving many fields, such as building materials, daily chemicals, food, medicine, etc.
