Kabhoni Chena Nhema

Chena Kabhoni Nhema, inozivikanwawo se hydrated silica kana silica yakapfava, ine zita remakemikari rekuti silicon dioxide (SiO₂), ihupfu huchena, husina chepfu, husina chimiro chena, husina chimiro chena. Hunotumidzwa zita racho nekuda kwechitarisiko chahwo chichena uye kugona kwahwo kushanda sechinotsiva black carbon.

• Chitarisiko: Hupfu chena kana granular kana kuti mabhuroko asina chimiro chakakwana.
• Hunhu hweMakemikari: Inonyungudika mu caustic alkalis uye hydrofluoric acid, isinganyungudike mumvura, zvinonyungudutsa, uye acids (kunze kwe hydrofluoric acid).
• Hunhu Hwemuviri: Inodzivirira kupisa kwakanyanya, haibati, haina kunaka, haina hwema, ine insulation yemagetsi yakanaka kwazvo.
• Nhamba yeCAS: 10279-57-9
• Nhamba yeEINECS: 238-878-4

II. Zvikamu Zvikuru uye Maumbirwo

Chinhu chikuru cheWhite Carbon Black isilicon dioxide, iyo inogona kumiririrwa nefomura yeSiO₂·nH₂O, uko nH₂O iripo muchimiro chemapoka ehydroxyl ari pamusoro. White Carbon Black chinhu chine maburi ane nzvimbo yakakura uye basa repamusoro.

III. Nzira dzekugadzirira

Nzira dzekugadzirira White Carbon Black dzinosanganisira nzira yegesi, nzira yemvura, uye nzira yekuora.

• Nzira yeGas-phase: Uchishandisa silicon chloride (yakadai sesilicon tetrachloride) sezvinhu zvakagadziriswa, White Carbon Black inogadzirwa kuburikidza ne flame hydrolysis pakupisa kwakanyanya. Gas-phase White Carbon Black ine zvakanakira saizi diki yezvikamu, nzvimbo yakakura chaiyo, uye kuchena kwakanyanya kwemakemikari, asi maitiro ekugadzirira akaomarara uye mutengo wakakwira.
• Nzira yeKunaya kwemvura: Silicon dioxide precipitate inogadzirwa nekuita sodium silicate neacid, uye White Carbon Black inowanikwa kuburikidza nekusefa, kuwacha, kuomesa, uye mamwe maitiro. Tekinoroji yekugadzira mvura White Carbon Black yakakura, uye michina iri nyore, asi chigadzirwa hachina basa rakawanda uye zvidimbu zvacho zvakaoma kudzora.

IV. Nzvimbo dzeKushandisa

Kabhoni Chena Nhema inoshandiswa zvakanyanya muminda yakasiyana-siyana nekuda kwehunhu hwayo hwakasiyana:

1. Indasitiri yeRabha: Chena Kabhoni Nhema chinhu chakakosha chinosimbisa zvigadzirwa zverabha, izvo zvinogona kuwedzera simba, kuramba kupera, kuramba kubvaruka, uye hunhu hwekudzivirira kukwegura kwezvigadzirwa zverabha. Inonyanya kushandiswa mukugadzira matai, sezvo ichigona kuwedzera kubata matai uye kuvandudza kuchengetedzeka kwekutyaira.
2. Indasitiri yePlastiki: Sechinhu chinosimbisa uye chinozadza, White Carbon Black inogona kuvandudza zvakanyanya simba, kuomarara, uye kuramba kupfeka kwepurasitiki, uye kuvandudza mashandiro epurasitiki.
3. Indasitiri yeCoatings: Chena Kabhoni Nhema, semushonga wekuzadza pigment, inogona kuvandudza simba rekufukidza, kunamira, uye kuramba kwecoatings mumamiriro ekunze, uye kuderedza mitengo yekufukidza.
4. Indasitiri yeMapepa: Semuchina wekuzadza wemhando yepamusoro, White Carbon Black inogona kuvandudza kuchena, kutsvedzerera, uye kupenya kwepepa, uye kuvandudza mashandiro ekudhinda kwepepa.
5. Indasitiri yeCeramics: Mukugadzirwa kwezvinhu zveceramic, White Carbon Black inoshandiswa zvakanyanya mukugadzira maglazes nemuviri, zvichivandudza simba, kuomarara, uye kuramba kupfeka kwezvinhu zveceramic.
6. Indasitiri yeInki: Semuchina wekuzadza pigment, White Carbon Black inogona kuvandudza simba rekufukidza, kunamira, uye kugadzikana kweinki, uye kuvandudza mashandiro ekudhinda einki.
7. Indasitiri yeZvizoro: Kabhoni Chena Nhema, semushonga wekuzadza nekukora, inogona kuvandudza kupfava, kugadzikana, uye kunzwa kwezvizoro, kudzora kuburitswa kwemafuta eganda, uye kuvandudza kunaka kweganda.
8. Indasitiri yeMishonga: Chena Kabhoni Nhema inonyanya kushandiswa mukugadzira mishonga, kuvandudza kupararira, kugadzikana, uye kuwanikwa kwemishonga, uye kuderedza migumisiro yakaipa.
