In order to improve the adsorptivity of bentonite raw ore granule, Ludox can be added.Ludox refers to nanometer
The silica dioxide granule of level dispersion liquid in water or in solvent.Owing to the SiO2 in Ludox contains
Substantial amounts of water and hydroxyl, therefore Ludox can also be expressed as SiO2.nH2O.Ludox is by silicic acid molecule
It is polymerized generation voluntarily, the most also can be polymerized generation gel further and settle out from solution
To come. when being used alone Ludox absorption, it understands self. polymerization, ' particle growth. surface reduces. absorbability
Decline.Additionally it is while Liquidity limit bores, and micelle surface charge is neutralized. the most quickly coalesce
And separate out. this is probably another reason that Ludox absorbability is the highest.Electronegative Ludox can adsorb
On the bentonite clay particle crystal layer end face of positively charged.Adsorbed Ludox grain can not carry out Blang again
Motion, decreases collision polymerization and grows up chance. and be distributed affected by the end face lotus locational space that powers on, that
It is the least that this combines chance of growing up, and this makes the sol particle granularity of absorption on end face less, remains
Bigger absorption surface.In the plane and end face of granule crystal layer, all there is suction in swelling after Ludox process
Attached cation capacity.The Liquidity limit ability just making it is both high, also than the raw material bentonite not processed
Higher than Ludox.You need to add is that, Ludox can be used known method to make by oneself by sodium silicate,
Do not repeat them here.
