I-Silica Efuthwe Ngama-Hydrophilic
Isingeniso Somkhiqizo
I-Fumed silica, noma i-pyrogenic silica, i-colloidal silicon dioxide, iyimpuphu emhlophe engaphelele enezinto eziphilayo enendawo ephezulu yobuso, usayizi wezinhlayiya eziyinhloko ze-nano-scale kanye nokuhlushwa okuphezulu (phakathi kwemikhiqizo ye-silica) kwamaqembu e-surface silanol. Izakhiwo ze-fumed silica zingashintshwa ngamakhemikhali ngokusabela kwala maqembu e-silanol.
I-silica efumile etholakalayo kwezentengiselwano ingahlukaniswa ngamaqembu amabili: i-silica efumile e-hydrophilic kanye ne-silica efumile e-hydrophobic. Isetshenziswa kabanzi njengesithako esibalulekile ezimbonini eziningi ezifana ne-silicone raber, upende kanye nepulasitiki.
Izici Eziyinhloko
1, ukuhlakazeka okuhle, ukulwa nokucwila okuhle kanye nokumuncwa.
2, Ku-silicone rabha: ukuqinisa okuphezulu, ukumelana nokudabuka okuphezulu, ukumelana okuhle kokuhuzuka, ukubonakala okuhle.
3, ngopende: ukulwa nokuwa, ukulwa nokuqina, ukuthuthukisa ukuzinza kombala, ukuthuthukisa ukusabalala kombala, ukuthuthukisa ukunamathela kwefilimu, ukulwa nokugqwala, ukungangeni manzi, ukuvimbela ukubhamuka, ukusiza ukugeleza, ukuthuthukisa ukulawula i-rheological.
4, Isebenza kungqimba ngayinye yopende (ingcina, ukumboza, uyinki) ukuthuthukisa ukuzinza kombala, ukuthuthukisa ukusabalala kombala, ukuthuthukisa ukunamathela kwefilimu, ukulwa nokugqwala, ukungangeni manzi, ukulwa nokuqina, ukulwa nokubhamuza, ikakhulukazi ekuqiniseni irabha ye-silicone, i-ejenti yokunamathela ye-thixotropic, i-ejenti yokulwa nokuqina kombala ohlelweni lokufaka imibala.
5, ngoba uhlelo loketshezi lungathola ukuqina, ukulawula i-rheology, ukumiswa, ukulwa nokuwohloka nezinye izindima.
6, Ukuze uhlelo oluqinile lungathuthukisa ukuthuthukiswa, ukumelana nokuguguleka nokunye.
7, Uhlelo lwempuphu lungathuthukisa ukugeleza kwamahhala futhi luvimbele ukuhlangana kanye neminye imiphumela. Lungasetshenziswa futhi njengokugcwalisa okusebenzayo okuphezulu kwerabha yemvelo neyokwenziwa, imithi kanye nezimonyo.

Isicelo Somkhiqizo
Isetshenziswa kakhulu kwirabha ye-silicone (HTV, RTV), opende, okokumboza, uyinki, izinto zikagesi, ukwenza iphepha, amafutha, amafutha ekhebula le-fibre-optic, ama-resins, ama-resins, ipulasitiki eqiniswe ngefayibha yengilazi, ingcina yengilazi (i-sealant), ama-adhesive, ama-defoamers, ama-solubilizer, amapulasitiki, izinto zobumba kanye neminye imboni.
Ukupakishwa Nokugcinwa
1. Ipakishwe ephepheni le-kraft elinezingqimba eziningi
Izikhwama ezingama-2.10kg ezifakwe epalethini
3. Kufanele igcinwe ephaketheni lokuqala endaweni eyomile
4. Kuvikelwe ezintweni ezishintshashintshayo
