Aia nā mea kalapona i nā mea porous. ʻO ka nui o ka porosity o nā huahana kalapona he 16% ~ 25%, a ʻo nā huahana graphite he 25% ~ 32%. ʻO ka loaʻa ʻana o ka nui o nā pores e loaʻa i ka hopena maikaʻi ʻole i nā ʻano kino a me nā waiwai a me ka hana o nā mea kalapona. No ka laʻana, me ka piʻi ʻana o ka porosity, emi ka nui o nā mea kalapona, piʻi ka resistivity, hoʻemi ka ikaika mechanical, hoʻemi ke kūpaʻa kemika a me ka corrosion, a piʻi ka permeability i nā kinoea a me nā wai. No laila, no kekahi mau mea kalapona hana kiʻekiʻe a me nā mea kalapona kūkulu ʻia, pono e hoʻokō ʻia ka compaction impregnation.
Hiki ke hoʻokō ʻia nā kumu aʻe ma o ka impregnation a me ka hoʻoponopono compaction:
(1) hoʻemi nui i ka porosity o ka huahana;
(2) Hoʻonui i ka nui o nā huahana a hoʻomaikaʻi i ka ikaika mechanical o nā huahana:
(3) Hoʻonui i ka uila a me ka wela o nā huahana;
(4) E ho'ēmi i ka permeability o ka huahana;
(5) E hoʻomaikaʻi i ka pale ʻana i ka oxidation a me ka corrosion kū'ē o ka huahana;
(6) Hiki i ka hoʻohana ʻana i ka impregnation lubricant ke hoʻomaikaʻi i ka pale ʻana o ka huahana.
ʻO ka hopena maikaʻi ʻole o ka impregnation a me ka densification o nā huahana kalapona ʻo ia ka piʻi iki o ka coefficient o ka hoʻonui wela.
