Vagadziri nevatengesi veChina Hydrophobic Fumed Silica

Silica Inofurwa Nemhepo Inovhundutsa

Mufananidzo wakaratidzwa weSilica Inofurwa neHydrophobic

tsananguro pfupi:

Fumed silica, kana kuti pyrogenic silica, colloidal silicon dioxide, ihupfu huchena husina kuumbwa husina kuumbwa hune nzvimbo yepamusoro, saizi huru yezvikamu zvidiki uye huwandu hwakanyanya (pakati pezvigadzirwa zvesilica) hwemapoka e silanol ari pamusoro. Hunhu hwe fumed silica hunogona kuchinjwa nemakemikari kuburikidza nekuita nemapoka aya e silanol.

Nhanganyaya yeChigadzirwa
Silica yakafurwa, kanasilica ine pyrogenic, silicon dioxide ye colloidal, ihupfu huchena husina kugadzirwa husina kugadzirwa hune nzvimbo chaiyo yepamusoro, saizi yezvikamu zvekutanga zve nano-scale uye huwandu hwakawanda (pakati pezvigadzirwa zve silica) hwemapoka e silanol ari pamusoro. Hunhu hwe silica inofurwa hunogona kuchinjwa nemakemikari kuburikidza nekuita nemapoka aya e silanol.
Silica inofemeswa inowanikwa mukutengeserana inogona kukamurwa kuita mapoka maviri: hydrophilic fumed silica uye hydrophobic fumed silica. Inoshandiswa zvakanyanya sechinhu chakakosha mumaindasitiri akawanda akadai se silicone rabha, pendi nemapurasitiki.

Zvivakwa zveChigadzirwa
1. Inoshandiswa muzvinhu zvakaoma zve polar, zvakaita se epoxy resin, polyurethane, vinyl resin, ine kukora kwakanaka uye thixotropic effect;
2. Inoshandiswa sechinokora, chinhu chinodzivirira kugadzikana uye chinodzivirira kudonha kwemusoni uye chinonamira tambo;
3. Mushonga unodzivirira kugadzika kwemafuta ane huwandu hwakawanda;
4. Inoshandiswa mu toner yekusunungura uye kudzivirira kuvharika kweganda;
5. Inoshandiswa mumapendi kuti ivandudze kugadzikana kwekuchengetedza;
6. Kubvisa tsvina zvakanaka mu defoamer;
