Nā hiʻohiʻona o kahi hoʻomaha
Nā laʻana o ka hoʻomaha ʻana

I ke kemika, a kāpae ʻO ia kahi ʻano o ka hoʻohuihui heterogeneous i hana ʻia e hoʻokahi a ʻoi paha mau mea i loko o kahi mokuʻāina paʻa i hoʻopuehu ʻia i kahi mea i loko o kahi wai a me nā kūlana ʻenekini. I kahi hoʻomaha, ʻaʻole i hoʻoheheʻe ʻia ka paʻa (pae i hoʻopuehu ʻia) i ka wai waena (ka wā hoʻohele). O kahi laʻana: wai ʻalani, ʻoiai e lana ana ka pulp a ʻaʻole hoʻohui ʻia i loko o ka wai waena, nā lāʻau pauka.

Hoʻohui ʻia kahi hoʻohui heterogeneous no ka mea hiki ke ʻike i nā ʻāpana i hana ʻia. Kūleʻa lākou i nā hui kūpaʻa ʻole, ʻoiai, ma muli o ka nui, nā ʻāpana paʻa i kahi hoʻomaha e kū mālie ke hoʻomaha ka hui.

Hiki iā ia ke lawelawe iā ʻoe: Nā hoʻohuihui o nā paʻa me nā wai

Nā hiʻohiʻona o kahi hoʻomaha

ʻIke maʻalahi lākou i nā hui ʻana no ka mea maʻamau opaque lākou.
ʻOiai ʻo ka hapanui e hana ʻia i nā mea paʻa a me nā wai (nā suspensions mechanical), hiki ke lilo i wai + wai a paʻa a wai ʻē paha. ʻO kahi laʻana o kahi mea paʻa i hoʻopuehu ʻia i ke kinoea ka aerosol.
I nā ʻoihana ʻokoʻa, hoʻohana ʻia nā mea e like me surfactants a me nā mānoanoa e pale i nā mea paʻa i ka hui ʻana mai ka noho ʻana.
Pono nā mea he nui e kāwili ʻia a hoʻoluliluli paha e hoʻi i ko lākou mokuʻāina kau ʻia.
ʻOkoʻa lākou i nā haʻina no ka mea ʻoi aku ka nui o nā ʻāpana paʻa, a i nā hāʻina e hoʻoheheʻe ʻia ka paʻa i ka wai, e hoʻoulu nei i ka hui like like.
ʻOkoʻa lākou mai colloids, no ka mea, i loko o ia mau mea ʻoi aku ka finer (ke anawaena ma waena o 10⁻⁹ a me 10⁻⁵ nanometer).
Hiki ke hoʻokaʻawale ʻia nā mea i haku ʻia e nā ʻano hana kino e like me ka kānana, centrifugation a me decantation.
