ʻIke ʻia ʻo Silica ma ke ʻano he silicone dioxide. He ʻano hana like ʻo Silica: e hoʻomalu i ka viscosity o kahi huahana, hoʻohui i ka nui, a hoʻemi i ka ʻike o ka formulation.Hiki iā ia ke hana ma ke ʻano he abrasive.Eia kekahi, hiki iā ia ke hana ma ke ʻano he mea lawe i nā emollients, a hiki ke hoʻohana ʻia e hoʻomaikaʻi i ka ʻili o ka ʻili.ʻO ka silica spherical he porous a hoʻopaʻa nui ʻia, me ka hiki ke hoʻopaʻa ʻia ma kahi o 1.5 mau manawa o kona kaumaha.ʻO kahi koi maʻamau e pili ana me ka silica ka mana ʻaila.Loaʻa ia i loko o nā sunscreens, scrubs, a me nā ʻano ʻē aʻe o ka mālama ʻili, ka hoʻomaʻemaʻe, a me ka hoʻomākaukau ʻana i ka lauoho.Ua hoʻohana maikaʻi ʻia i nā ʻano hypoallergenic a i hoʻāʻo ʻia i ka allergy.
ʻEli ʻia ʻo Silica (SiO2) (RI: 1.48) mai loko mai o nā waiho ʻana o ka pōhaku like me ka paʻakai palupalu diatomaceous (keiselghur).He pūʻulu koʻikoʻi kēia o nā puaʻa extender, i hoʻohana ʻia i nā ʻano nui like ʻole.Hoʻohana ʻia lākou ma ke ʻano he mea hoʻoheheʻe ʻia e hōʻemi i ka ʻōlinolino o nā uhi maʻemaʻe a me ka hāʻawi ʻana i nā waiwai kahe o ka shear thinning i nā uhi.He pipiʻi lākou.
Hoʻohana ʻia ʻo Silicon(IV) oxide, amorphous e like me nā mea lawe, nā mea kōkua hana, anti-caking a me nā mea hoʻokahe manuahi i ka hānai holoholona.Nā noi Defoamer e like me ka pena, ka meaʻai, ka pepa, ka textile a me nā noi ʻoihana ʻē aʻe.Hoʻohana ʻia ʻo Synthetic silicon dioxide ma ke ʻano he mea mālama rheology i loko o nā plastics.Hoʻohana ʻia ia e hana i nā adhesives, sealants a me nā silicones.
Ka hana ʻana i ke aniani, ke aniani wai, refractory, abrasives, ceramics, enamels;decolorizing a hoʻomaʻemaʻe aila, petroleum huahana, etc.;i loko o ka hui ʻana a me ka wili ʻana, ka ferrosilicon, nā poni no ka hoʻolei ʻana;e like me ka anticaking a me ka defoaming agent.
