Sodium Bentonite Vs Calcium Bentonite
In practical applications, small and medium-sized enterprises often use excavators to mix bentonite and soda ash and stack them for aging, resulting in poor stability of sodium formation. If the Internet of Things technology is introduced to implement online monitoring and control, the sodium formation process can be stabilized. Read More About
