Loaʻa iā ia nā hiki adsorption maikaʻi loa, e hiki ai iā ia ke huki a paʻa i nā mea like ʻole, me nā aila, nā hui organik, a me nā metala kaumaha. ʻO kēia ka mea e pono ai i nā noi e pono ai ke kaʻina hana hoʻomaʻemaʻe a hoʻokaʻawale paha. ʻO ka nui o nā ʻāpana liʻiliʻi o ka pauka bentonite e kōkua i kona ʻāpana ʻili nui, e hoʻonui hou ana i kona pono adsorption.

ʻO kekahi ʻano koʻikoʻi ʻo thixotropy, ʻo ia hoʻi ke hana nei i kahi ʻano gel-like i ka wā e hoʻomaha ai akā lilo i wai i ka wā e hoʻonāukiuki ʻia ai. He mea maikaʻi kēia waiwai i ka ʻeli ʻana i nā wai, kahi e koʻikoʻi ai ka mālama ʻana i kahi viscosity paʻa ma lalo o nā kūlana like ʻole. Hōʻike pū ka pauka Bentonite i ka plasticity maikaʻi, e ʻae ana iā ia e hoʻohālikelike a hoʻoheheʻe maʻalahi i ka wā e hui pū ʻia me ka wai.

ʻO kona kūpaʻa kemika kekahi pono ʻē aʻe, ʻoiai hiki iā ia ke kū i nā ʻano mahana a me nā pae pH me ka ʻole o ka hōʻino nui ʻana. Hōʻoia kēia kūpaʻa i ka hana mau i nā ʻano ʻoihana like ʻole, mai nā kaʻina hana hao wela kiʻekiʻe a hiki i nā hana hoʻonā waikawa a alkaline paha.
