What Is The Difference Between Heavy Soda Ash And Light Soda Ash

There is no difference in chemical formula between light soda ash and heavy soda ash. There are two main types of soda ash products, namely heavy soda ash and light soda ash. 

The difference between light soda ash and heavy soda ash:

1. Different physical properties Heavy pure alkaline form: white granular anhydrous, easily soluble in water, can absorb CO2 and water when exposed to the air at room temperature, release heat, and gradually turn into NaHCO3 and agglomerate. Generally, the density of light soda ash is 500-600kg/m3, and the density of heavy soda ash is 1000-1200kg/m3.

2. The price difference of heavy soda ash is about 100--200 yuan higher than that of light soda ash.

3. Differences in production methods: Light soda ash is mainly produced by the ammonia-alkali method. Using raw salt and limestone as raw materials, light soda ash is produced by chemical synthesis method, and heavy soda ash is produced by solid phase hydration method. Heavy soda ash is mainly produced by trona method, using trona as raw material to produce heavy soda ash by evaporation method or carbonization method. Extended information: Soda ash generally refers to sodium carbonate (Na2CO3) with a molecular weight of 105.99. The purity of chemicals is more than 99.5% (mass fraction), also known as soda ash, but it is classified as salt, not alkali. Also known as soda or soda ash in international trade. It is an important organic chemical raw material, mainly used in the production of flat glass, glass products and ceramic glaze. It is also widely used in daily washing, acid neutralization and food processing. This product is weakly irritating and weakly corrosive. Direct contact can cause skin and eye burns. Inhalation of its dust and fumes during production can cause respiratory irritation and conjunctivitis, as well as nasal mucosal ulcers, atrophy and perforation of the nasal septum. Eczema, dermatitis, corneal ulcers and skin laxity can occur with prolonged contact with the solution. Workers exposed to this product have an increased incidence of respiratory diseases. Ingestion can cause gastrointestinal burns, mucosal erosion, bleeding and shock.

Usage notice:

1. Wear appropriate protective clothing and gloves.

2. After accidental contact with eyes, please rinse immediately with plenty of water and seek medical advice.

3. Do not inhale dust.

4. Wear appropriate protective clothing. Wear goggles or a mask.

5. Toxic to aquatic organisms and may have long-term adverse effects on the water environment.

6. Irritating to eyes, respiratory system and skin.

7. Stimulates the respiratory system and skin.
