Mokotla oa caustic o entsoe joang?
Mokhoa o tloaelehileng haholo oa indasteri ke electrolysis, e arotsoeng:
◆Diaphragm electrolysis: After salting the raw salt, add soda ash, caustic soda, and barium chloride refiners to remove impurities such as calcium, magnesium, and sulfate ions. Ebe u eketsa Sodium Polycrylate kapa ea tlhaselo ea mapolanka ho ea tankeng ea Tlhaloso ho ea potlakisa pula. Kamora ho fouta ea lehlabathe, eketsa acid acid ho khelosa. Brine e reriloe 'me e rometsoe ho electrolysis. Mollo oa elektrolyte o reriloe, o mouoane, o ile a longoa ebile a kokobetse ho fumana soda ea metsi a metsi. Ho belisa ho eketsehileng ho pheha le ho tsepamisa mohopolo ho tla fumana sehlahisoa se tiileng sa sotic caustic. Metsi a letsoai la letsoai a sebelisoa bakeng sa letsoai.
