PH value 8.6 Uses: Used as food fermentation, detergent ingredient, carbon dioxide foamer, pharmacy, leather, ore milling and metallurgy, detergent for wool, extinguisher and metal heat-treating, fiber and rubber industry, etc. Producing methods: Carbonization process: Natural soda is firstly dissolved into solution (Na2CO3) and filtrated. The clear solution is then fed to carbonizing tower; accordingly, CO2 is compressed and bubbled up from the bottom of the tower. After carbonization, the slurry will be flowed from the bottom and separated. Dried to the finished product.
