Vermiculite flake
ʻO ka vermiculite kahi mineral silicate, ʻo ia ka mica sub-organism.ʻO kona hui kemika nui: 22MgO · 5Al2O3 · Fe2O3 · 22SiO2 · 40H2O ʻO ke ʻano molekole theoretical ma hope o ka ʻai ʻana a me ka hoʻonui: (OH) 2 (MgFe) 2 · (SiAlFe) 4O104H2O
ʻO ka vermiculite ʻeleʻele mua he ʻano papa me ka liʻiliʻi o ka wai ma waena o nā papa.Ma hope o ka hoʻomehana ʻana ma 900-950 ℃, hiki ke hoʻoheheʻe ʻia, ʻāhaʻi a hoʻonui ʻia i 4-15 mau manawa o ka leo kumu, e hana ana i kahi mea kino māmā porous.Loaʻa iā ia ka thermal insulation, ke kūpaʻa wela kiʻekiʻe, ka insulation, antifreeze, ke kū'ē i ke ōlaʻi, ka waikawa a me ka alkali corrosion kū'ē, ka leo insulation a me nā waiwai ʻē aʻe.
