Downstream of the soda ash industry chain, glass is the most important downstream demand for soda ash, accounting for about 50% of the demand, including flat glass, daily-use glass, and photovoltaic glass. Heavy alkali is mainly used in the production of flat glass.
Basic knowledge and application field of soda ash The downstream of soda mainly includes plate glass, photovoltaic glass, daily glass, paucine, baking soda, sodium, detergent and other industries.
Baking soda and sodium carbonate are two commonly used household substances that are often mistaken for being the same thing. However, despite their similar appearance, these two compounds have distinct properties and uses. In this article, we will delve into the world of baking soda and sodium carbonate to understand their individual characteristics and shed light on the key differences between them.
Natural citric acid exists in plants, such as lemon, citrus, pineapple, etc. Synthetic citric acid is produced by fermentation with sugar, molasses, starch, grapes and other sugary substances. It can be divided into anaqueous and whole lemon, which is colorless transparent crystal or white powder, a
