I-Hydrophilic Fumed Silica
Isingeniso Somkhiqizo
I-silica evuthayo, noma i-pyrogenic silica, i-colloidal silicon dioxide, iyimpushana emhlophe e-amorphous ephilayo enendawo ethize ephezulu, usayizi wezinhlayiya zesikali se-nano kanye nokuhlushwa okuphezulu (phakathi kwemikhiqizo ye-silica) kwamaqembu e-silanol angaphezulu. Izakhiwo ze-silica evuthayo zingashintshwa amakhemikhali ngokusabela kulawa maqembu e-silanol.
I-silica evuthayo etholakalayo kwezohwebo ingahlukaniswa ngamaqembu amabili: i-hydrophilic fumed silica ne-hydrophobic fumed silica. isetshenziswa kabanzi njengesithako esibalulekile ezimbonini eziningi ezifana nezimboni zenjoloba ye-silicone, upende kanye nepulasitiki.
Izici Eziyinhloko
1, ukuhlakazeka okuhle, anti-ukucwila okuhle kanye adsorption.
2, Kurabha ye-silicone: ukuqinisa okuphezulu, ukumelana nezinyembezi eziphakeme, ukumelana okuhle kokuhunyazwa, ukubonakala okuhle.
I-3, ngopende: i-anti-sagging, i-anti-settlement, ithuthukisa ukuzinza kwe-pigment, ithuthukise ukuhlakazeka kwe-pigment, ithuthukise ukunamathela kwefilimu, i-anti-corrosion, ingangeni manzi, ivimbele ukugwedla, isiza ukugeleza, ithuthukise ukulawula kwe-rheological.
4, Isebenza kungqimba ngalunye lukapende (okunamathelayo, okokunamathela, uyinki) ukuze kuthuthukiswe ukuzinza kwe-pigment, ukuthuthukisa ukuhlakazeka kwe-pigment, ukuthuthukisa ukunamathela kwefilimu, ukulwa nokugqwala, ukuvikela amanzi, ukulwa nokuhlalisa, ukunqanda ukubhubhuzela, ikakhulukazi ukuqinisa irabha ye-silicone, i-ejenti enamathelayo ye-thixotropic, i-anti-settling ejenti yesistimu yombala.
5, ngoba uhlelo liquid angathola ukuqina, ukulawula rheology, ukumiswa, anti-sagging kanye nezinye izindima.
I-6, Ukuze uhlelo oluqinile lungathuthukisa ukuthuthukiswa, ukumelana nokugqoka njalonjalo.
I-7, i-powder system ingathuthukisa ukugeleza kwamahhala futhi ivimbele i-agglomeration neminye imiphumela. Ingasetshenziswa futhi njengesigcwalisi esiphezulu esisebenzayo serabha yemvelo neyokwenziwa, imithi kanye nezimonyo.

Isicelo somkhiqizo
Isetshenziswa kakhulu kurabha ye-silicone (i-HTV, i-RTV), upende, okokunamathela, oyinki, i-electronics, ukwenza iphepha, ugrisi, igrisi yekhebula le-fibre-optic, ama-resin, ama-resin, i-glass fibre eqinisiwe ipulasitiki, ingcina yengilazi (i-sealant), izinto zokunamathisela, ama-defoamers, ama-solubilizer, amapulasitiki, izitsha zobumba nezinye izimboni.
Ukupakisha kanye Nesitoreji
1. Ihlanganiswe ngephepha le-kraft lesendlalelo esiningi
Izikhwama ze-2.10kg ku-pallet
3. Kufanele igcinwe ephaketheni lokuqala endaweni eyomile
4. Ivikelwe ezintweni eziguquguqukayo
