ʻO ka pahu silikoni ka māhele noi nui loa o ka silica fumed.
Hāʻawi ʻo Fumed silica i kahi hopena hoʻoikaika nui o ka silicone rubber:
1. Hoʻopau i ka ikaika a me ka elasticity:
He haʻahaʻa loa ka ikaika o ka rubber silicone i hoʻopiha ʻole ʻia (ʻaʻole hiki ke hana i kahi hale paʻa, a ʻaʻole hiki ke hoʻohua. Hiki i nā ʻāpana nanoscale o ka silica fumed a me kā lākou kaulahao kūʻokoʻa / dendritic aggregate structure hiki ke komo hohonu i loko o ke kaulahao molekala o ka silicone rubber. Ma o ka hoʻopili kino ʻana a me ka launa pū ʻana ma waena o nā pūʻulu silanol i luna a me nā molekole kaila silikoni (nā paʻa hydrogen, nā pūʻali van der Waals), ua hoʻokumu ʻia kahi ʻano pūnaewele mana ʻekolu{2}}mana.
2.Enhance nā waiwai mechanical: Hoʻonui nui i ka ikaika tensile, ka ikaika o ka waimaka, ke kūpaʻa a me ka pale ʻana o nā papa pua. Me ka lawa ʻole o ka silica fumed, ʻeleʻele loa ka papa puaʻa, weluwelu maʻalahi a nele i ka waiwai kūpono.
