Contact information of sodium carbonate manufacturer Zaozhuang sodium carbonate manufacturer

In 1861, Ernest Solvay of Belgium invented soda ash and obtained a patent. Since the protection of technical secrets has not been widely applied, it made a breakthrough from the United States in the 1920s. In particular, China's chemical industry Hou Debang published the book Soda Ash Manufacturing in 1932, which will be kept secret for 70 years, and Solvay Method was published. Hou Debang also created Hou's caustic soda process in 1939-1942, and set up a pilot plant in Sichuan. In 1952, a joint alkali workshop was set up in Dalian Chemical Plant. The NA method introduced by Asahi Nippon Co., Ltd. in Japan is essentially a compromise method between soda ash and ammonia soda. The proportion of soda ash and ammonium chloride can be adjusted at will

chemical property
The aqueous solution of sodium carbonate is alkaline and corrosive to a certain extent. It can double decompose with acid and some calcium and barium salts. The solution is alkaline and can make phenolphthalein red.

According to the principle that the solubility of NH4Cl is greater than that of NaCl, but smaller than that of NaCl at low temperature, fine salt powder is added to the mother liquor at 278K~283K (5 ℃~10 ℃), so that NH4Cl can be isolated as nitrogen fertilizer.

As a buffer, neutralizer and dough improver, it can be used for cakes and flour food, and can be used moderately according to production needs.
As a detergent, it is used for wool rinsing, bath salt and medicine, and as an alkaline agent in tanning.

soda
Soda is a transliteration of Soda, and its chemical formula is Na2CO3. It has many names, which are called sodium carbonate in science and soda ash in common use. It is called hydrated sodium carbonate with crystal water, including sodium carbonate monohydrate (Na2CO3 · H2O), sodium carbonate heptahydrate (Na2CO3 · 7H2O) and sodium carbonate decahydrate (Na2CO3 · 10H2O).

Big soda is the common name of sodium thiosulfate, also called Haibo (transliteration of Hypo). Hydrate contains five crystal water (Na2S2O3 · 5H2O), so it is also called sodium thiosulfate pentahydrate.
