Anhui Light Pure Soda Ash

Sodium CarbonateSodium carbonate, commonly known as soda ash, soda lime, or alkali powder, is a white powdered and crystalline substance. Its aqueous solution is alkaline, and it has a strong hygroscopic property, readily absorbing moisture in humid air. Sodium carbonate is categorized into industrial-grade and food-grade, and can be further divided into light-duty and heavy-duty based on bulk density. Additionally, there are byproduct soda, fallen soda, and common soda, among others.

Application

Industrial-grade:

Glass production is a major industrial consumer of soda ash, widely used in float glass, picture tube glass shells, optical glass, etc., and can also act as a clarifier to remove bubbles from the glass melt.

② High-purity soda ash reduces the scattering of alkali dust, lowers raw material consumption, saves costs, and also lessens the erosion of alkali powder on refractory materials, thereby extending the service life of the kiln.

Sodium carbonate solutions, due to hydrolysis, become alkaline and can undergo saponification with oil污, making them suitable for use in detergent production.

④ Used in leather processing for degreasing raw hides and neutralizing chrome-tanned leather to increase the viscosity of the chrome tanning solution.

⑤ Soda ash is used in papermaking as a buffering agent to leach out lignin, allowing cellulose to disperse into pulp.

Food-grade:

Food-grade soda ash can be used as a buffering agent, neutralizer, and dough conditioner for bakery and pasta products.

② Lye water, also known as alkali water, is a compound food additive traditionally used as a base ingredient in Cantonese-style pastries.
