Hydrophilic fumed Silica
Ọja Ifihan
Silica fumed, tabi pyrogenic silica, colloidal silicon dioxide, jẹ amorphous funfun inorganic lulú eyiti o ni agbegbe agbegbe ti o ga, iwọn patiku akọkọ ti nano-iwọn ati iwọn giga (laarin awọn ọja yanrin) ifọkansi ti awọn ẹgbẹ silanol dada. Awọn ohun-ini ti silica fumed le jẹ atunṣe kemikali nipasẹ iṣesi pẹlu awọn ẹgbẹ silanol wọnyi.
Silica fumed ti o wa ni iṣowo le pin si awọn ẹgbẹ meji: siliki fumed hydrophilic ati silica fumed hydrophobic. o jẹ lilo pupọ bi eroja pataki ni ọpọlọpọ awọn ile-iṣẹ bii roba silikoni, kikun ati awọn ile-iṣẹ pilasitik.
Awọn abuda akọkọ
1, ti o dara pipinka, ti o dara egboogi-sinking ati adsorption.
2, Ni roba silikoni: imuduro giga, resistance omije giga, resistance abrasion ti o dara, akoyawo to dara.
3, ni kikun: egboogi-sagging, anti-farabalẹ, mu iduroṣinṣin pigment, mu pigment pipinka, mu film adhesion, egboogi-ipata, mabomire, dena bubbling, ran sisan, mu rheological Iṣakoso.
4, Ti o wulo fun awọ-awọ kọọkan (adhesive, cover, inki) lati mu iduroṣinṣin pigment, mu pipinka pigment, mu imudara fiimu, egboogi-ipata, mabomire, egboogi-farabalẹ, egboogi-bubbling, paapaa fun imudara silikoni roba, oluranlowo thixotropic adhesive, anti-settling agent fun eto awọ.
5, fun eto omi le gba nipọn, iṣakoso rheology, idadoro, egboogi-sagging ati awọn ipa miiran.
6, Fun eto ti o lagbara le mu ilọsiwaju dara si, aṣọ-sooro ati bẹbẹ lọ.
7, Fun eto lulú le mu ilọsiwaju ti o ni ọfẹ ati ki o dẹkun agglomeration ati awọn ipa miiran. O tun le ṣee lo bi kikun ti nṣiṣe lọwọ giga fun adayeba ati roba sintetiki, oogun ati awọn ohun ikunra.
