China Hydrophobic Fumed Silika opanga ndi ogulitsa

Hydrophobic Fumed Silika

Hydrophobic Fumed Silica Chithunzi Chowonetsedwa

Kufotokozera mwachidule:

Silika yofukizira, kapena silika ya pyrogenic, colloidal silicon dioxide, ndi amorphous white inorganic powder yomwe ili ndi malo apamwamba kwambiri, kukula kwa tinthu tating'onoting'ono tomwe timakhala tinthu tating'onoting'ono (pakati pa zinthu za silika) ndende yamagulu a silanol pamwamba. The katundu wa fumed silica akhoza kusinthidwa mankhwala ndi zochita ndi magulu silanol.

Chiyambi cha Zamalonda
Silika yamoto, kapenasilika pyrogenic, colloidal silicon dioxide, ndi amorphous white inorganic powder yomwe ili ndi malo apamwamba kwambiri, kukula kwa tinthu tating'onoting'ono kakang'ono ka nano ndi kuchuluka kwambiri (pakati pa zinthu za silika) ndende yamagulu a silanol. The katundu wa fumed silica akhoza kusinthidwa mankhwala ndi zochita ndi magulu silanol.
Silika yofukiza yamalonda yomwe ilipo imatha kugawidwa m'magulu awiri: hydrophilic fumed silica ndi hydrophobic fumed silica. amagwiritsidwa ntchito kwambiri ngati chinthu chofunikira m'mafakitale ambiri monga mphira wa silicone, mafakitale a utoto ndi mapulasitiki.

Zida Zamalonda
1. Amagwiritsidwa ntchito muzamadzimadzi zovuta za polar, monga epoxy resin, polyurethane, vinyl resin, ndi kukhuthala kwabwino komanso thixotropic;
2. Amagwiritsidwa ntchito ngati thickening, wothandizira thixotropic, anti-kukhazikitsa ndi anti-sagging mu seamstress ndi chingwe zomatira;
3. Anti-kukhazikitsa wothandizira kwa mkulu kachulukidwe filler;
4. Amagwiritsidwa ntchito mu tona pomasula ndi kutsutsa-caking;
5. Amagwiritsidwa ntchito mu utoto kuti apititse patsogolo kukhazikika kosungirako;
6. Wabwino defoaming zotsatira mu defoamer;
