Ua kapa ʻia hoʻi ka alumini hydroxide kumu he pauka mineral kūlohelohe, ʻo kona ʻike i loko o nā ʻāpana ʻekolu e noho ana i kahi hapa nui. I loko o ka pōhaku artificial ʻoi aku ka maikaʻi, ʻo kona ʻike e noho ana i 30%. Me ka resin polyester ma ke ʻano he mea kumu, a laila e hoʻohui i ka alumini hydroxide a me kekahi pena palekana kaiapuni, e hana i ke ʻano o ka ʻili pōhaku artificial i ikaika loa, laina hana lako lawe nui ʻia, kūpaʻa ka maikaʻi, liʻiliʻi ka ʻokoʻa kala batch, maikaʻi ka ʻāpana mea, manaʻo silika, maikaʻi ka hana kū'ē uv, e mae. I waena o lākou, hilinaʻi ka mea pale ahi pōhaku artificial i ka alumini hydroxide e loaʻa ana i ʻekolu mau molekala wai, ʻaʻole ia e hana i nā kinoea ʻawaʻawa a me nā kinoea corrosive i ka wā pyrolysis. I ka wā pyrolysis, hoʻopili ia i ka wela a hoʻokuʻu i ka mahu wai.
Inā ʻo ka nui o ka alumini hydroxide i hoʻohana ʻia a hiki i ka 30%, a ʻo ka helu o ka mesh e ana i ka nui o ka ʻāpana o ka ʻāpana inā a hiki i ka 2000 mesh, he maikaʻi ke ʻano o ia pōhaku hana. ʻO ka nui o ka mesh, ʻoi aku ka maikaʻi o ka ʻāpana a i ʻole ka pauka. Inā hoʻohui ʻia i loko o ka mea kūlohelohe, ʻoi aku ka paʻa o ke ʻano ma waena o nā molekala, ʻaʻohe pores a me nā pores, no laila ʻaʻole maʻalahi ka ʻaila a i ʻole kekahi mau haumia lepo, ka lepo. Ma ka ʻili ʻaʻohe pore a me ka stoma, hiki ke wehe ʻia ka ʻōpala paʻakikī, e like me ka māka uahi, ka ʻaila. I ka loaʻa ʻole o nā pores a me nā pores ma ka ʻili, ʻaʻole hiki ke ola ka ʻōpala, ka puʻuwai bacteria a me nā microorganism ʻē aʻe, he mea nui loa ka helu kauoha ʻike ʻia a me ka palekana o ke kaiapuni a me ka hoʻomaʻemaʻe.
ʻO ka hoʻohui ʻana o ka alumini hydroxide hiki ke hoʻolilo i ka pōhaku hana i ʻoi aku ka liʻiliʻi, i mea e ikaika loa ai ke hoʻohana, a e like me kekahi mau mea haumia a lepo paha, ʻaʻole maʻalahi ke komo i loko.
