Hydrophilic fumed Silica
Okwu Mmalite ngwaahịa
Fumed silica, ma ọ bụ pyrogenic silica, colloidal silicon dioxide, bụ amorphous ọcha inorganic ntụ ntụ nke nwere elu kpọmkwem n'elu ebe, nano-ọnụ ọgụgụ isi urughuru size na a dịtụ elu (n'etiti silica ngwaahịa) ịta nke elu silanol iche iche. Enwere ike gbanwee akụrụngwa nke silica fumed site na mmeghachi omume nke otu silanol ndị a.
Enwere ike kewaa silica fumed nke dị na ahịa ụzọ abụọ: silica fumed hydrophilic na silica hydrophobic fumed. a na-ejikarị ya eme ihe dị ka ihe dị mkpa n'ọtụtụ ụlọ ọrụ dịka silicone roba, agba na ụlọ ọrụ plastik.
Njirimara isi
1, ezigbo mgbasa, ezigbo mgbochi imi na adsorption.
2, Na silicone roba: akwa mkwado, akwa akwa mgbochi, ezigbo abrasion mgbochi, ezi nghọta.
3, na agba: mgbochi-sagging, mgbochi-edozi, melite pigmenti kwụsie ike, melite pigmenti dispersion, melite film adhesion, mgbochi corrosion, waterproof, igbochi bubbling, enyemaka eruba, welie rheological akara.
4, Ọdabara na nke ọ bụla agba oyi akwa (nrapado, mkpuchi, ink) ka mma pigment kwụsie ike, melite pigmenti dispersion, melite film adhesion, mgbochi corrosion, waterproof, mgbochi-edozi, mgbochi bubbling, karịsịa maka silicone roba ume, nrapado thixotropic gị n'ụlọnga, mgbochi-edozi onye nnọchiteanya maka agba usoro.
5, n'ihi na mmiri mmiri usoro nwere ike inwe ndim, rheology akara, nkwusioru, mgbochi sagging na ndị ọzọ ọrụ.
6, N'ihi na siri ike usoro nwere ike melite nkwalite, eyi-eguzogide na na.
7, N'ihi na usoro ntụ ntụ nwere ike imeziwanye usoro n'efu ma gbochie agglomeration na mmetụta ndị ọzọ. Enwere ike iji ya dị ka ihe mkpuchi na-arụ ọrụ dị elu maka rọba eke na nke sịntetik, ọgwụ na ihe ịchọ mma.
