Difference between natural sodium based bentonite and artificial sodium based bentonite
Temperature resistance of natural 500 degrees after 3 hours of drying (blue suction, swelling index, swelling value), decline or not decay of the indicatorsArtificial 500 degree drying 3 hours (blue absorption, swelling index, swelling value) attenuation more than 30%, even become dead soilThe artificial sodium bentonite was exposed to the outside world for half a year and became a calcium soil
React naturally with acid; react artificially; react with gas (as in expansion)
Difference: pH value is less than 8, artificial 8 or more
