Thread Content
Does any expert have domestic and foreign product standards for industrial grade and food grade soda ash?
GB210-1992 has been implemented since 1992* * Standard, new implementation on October 1, 2004 * * Standard GB210.1-2004, which is based on the British standard BS3674: Redrafted in 1981 (1886), it is an internationally advanced level. Compared with the quality of American trona, the quality of soda ash in my country has high salt content and poor whiteness. The salt content of trona in the United States is generally less than 0.2%, while the alkali in my country generally contains about 0.5% salt. ； The whiteness of soda ash in my country is generally lower than 90 degrees, which is lower than that of American trona.
It seems that Haichuan Chlor-Alkali does not have many technical personnel.
