Silica Inonhuhwirira Mvura
Nhanganyaya yeChigadzirwa
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.
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.
Hunhu Hukuru
1, kupararira kwakanaka, kudzivirira kunyura uye kunyudzwa zvakanaka.
2, Murabha resilicone: kusimbiswa kwakanyanya, kuramba kubvaruka kwakanyanya, kuramba kukwesha zvakanaka, kujeka kwakanaka.
3, mupendi: inodzivirira kudzika, inodzivirira kugadzikana, inovandudza kugadzikana kwepigment, inovandudza kupararira kwepigment, inovandudza kunamira kwefirimu, inodzivirira ngura, isingapindi mvura, inodzivirira kufashaira, inobatsira kuyerera, inovandudza kudzora rheological.
4, Inoshanda kune pendi yega yega (inonamira, inoputira, inki) kuvandudza kugadzikana kwepigment, kuvandudza kupararira kwepigment, kuvandudza kunamira kwefirimu, kudzivirira ngura, kudzivirira mvura, kudzivirira kugadzika, kudzivirira kubhubhubhu, kunyanya pakusimbisa rabha yesilicone, adhesive thixotropic agent, adhesive anti-settling agent yekuisa ruvara.
5, nekuti sisitimu yemvura inogona kuwana thickening, rheology control, suspension, anti-sagging uye mamwe mabasa.
6, Nekuti sisitimu yakasimba inogona kuvandudza kukwidziridzwa, kusakara uye zvichingodaro.
7, Hupfu hunogona kuvandudza kuyerera kwemvura uye kudzivirira kusangana kwemvura nezvimwe zvinokanganisa. Hunogona zvakare kushandiswa sechinozadza chakasimba cherabha yechisikigo neyekugadzira, mishonga nezvizoro.

Kushandiswa Kwechigadzirwa
Inonyanya kushandiswa mu silicone rabha (HTV, RTV), pendi, machira ekuputira, inki, zvemagetsi, kugadzira mapepa, girizi, fiber-optic cable greasi, maresini, maresini, girazi fiber reinforced plastic, girazi rinonamira (sealant), zvinonamira, zvinobvisa mafoamer, zvinonyungudutsa, mapurasitiki, zviumbwa zvedongo nezvimwe zvinhu.
Kurongedza uye Kuchengeta
1. Yakaputirwa mupepa rekugadzira rakasiyana-siyana
Mabhegi e2.10kg ari papallet
3. Inofanira kuchengetwa mupakeji yekutanga munzvimbo yakaoma
4. Inodzivirirwa kubva kuzvinhu zvinopfakanyika
