I-White Carbon Black, eyaziwa nangokuthi i-hydrated silica noma i-silica elula, enegama lamakhemikhali elithi i-silicon dioxide (SiO₂), iyimpuphu emhlophe, engenabo ubuthi, e-amorphous nanometer-scale powder. Iqanjwe ngokubukeka kwayo okumhlophe kanye nekhono layo lokusebenza esikhundleni se-carbon black.

I. Ulwazi Oluyisisekelo

• Ukubukeka: Impuphu emhlophe noma amabhlogo acwebezelayo noma anomumo ongavamile.
• Izakhiwo Zamakhemikhali: Incibilika kuma-alkali e-caustic kanye ne-hydrofluoric acid, ayincibiliki emanzini, ezinyibilikisi, kanye nama-asidi (ngaphandle kwe-hydrofluoric acid).
• Izakhiwo Ezibonakalayo: Ukumelana nokushisa okuphezulu, akushisi, akunambitheki, akunaphunga, kunokushisa kukagesi okuhle kakhulu.
• Inombolo ye-CAS: 10279-57-9
• Inombolo ye-EINECS: 238-878-4

II. Izingxenye Eziyinhloko kanye Nesakhiwo

Ingxenye eyinhloko ye-White Carbon Black yi-silicon dioxide, engamelwa yifomula i-SiO₂·nH₂O, lapho i-nH₂O ikhona ngesimo samaqembu e-surface hydroxyl. I-White Carbon Black iyinto enesimbobo enendawo enkulu ethile kanye nomsebenzi wobuso.

III. Izindlela Zokulungiselela

Izindlela zokulungiselela i-White Carbon Black zifaka phakathi indlela yesigaba segesi, indlela yokupholisa, kanye nendlela yokubola.

• Indlela Yesigaba Segesi: Kusetshenziswa ama-silicon chloride (njenge-silicon tetrachloride) njengezinto zokusetshenziswa, i-White Carbon Black ikhiqizwa nge-flame hydrolysis emazingeni okushisa aphezulu. I-Gas-phase White Carbon Black inezinzuzo zobukhulu bezinhlayiya ezincane, indawo enkulu ethile, kanye nobumsulwa obuphezulu bamakhemikhali, kodwa inqubo yokulungiselela iyinkimbinkimbi futhi izindleko ziphakeme kakhulu.
• Indlela Yokuna Kwemvula: I-silicon dioxide precipitate ikhiqizwa ngokuphendula i-sodium silicate ne-asidi, bese kuba yi-White Carbon Black etholakala ngokuhlunga, ukuwasha, ukomisa, nezinye izinqubo. Ubuchwepheshe bokukhiqiza imvula I-White Carbon Black ivuthiwe, futhi imishini ilula, kodwa umkhiqizo unomsebenzi ophansi futhi izinhlayiya kunzima ukuzilawula.

IV. Izindawo Zokufaka Isicelo

I-White Carbon Black isetshenziswa kabanzi emikhakheni eyahlukene ngenxa yezakhiwo zayo ezihlukile:

1. Imboni Yenjoloba: I-White Carbon Black iyisithako esibalulekile sokuqinisa imikhiqizo yerabha, esingathuthukisa amandla, ukumelana nokuguguleka, ukumelana nokudabuka, kanye nezakhiwo zokulwa nokuguga kwemikhiqizo yerabha. Isetshenziswa kakhulu ekukhiqizeni amathayi, njengoba ingandisa ukubamba amathayi futhi ithuthukise ukuphepha kokushayela.
2. Imboni Yepulasitiki: Njenge-ejenti yokuqinisa nokugcwalisa, i-White Carbon Black ingathuthukisa kakhulu amandla, ubulukhuni, kanye nokumelana nokuguguleka kwamapulasitiki, futhi ithuthukise ukusebenza kokucubungula kwamapulasitiki.
3. Imboni Yezimbozo: I-Carbon Emhlophe Emnyama, njengokugcwalisa umbala, ingathuthukisa amandla okumboza, ukunamathela, kanye nokumelana nesimo sezulu kwezingubo, futhi inciphise izindleko zokugqoka.
4. Imboni Yephepha: Njengokugcwalisa kwekhwalithi ephezulu, i-White Carbon Black ingathuthukisa ubumhlophe, ukushelela, kanye nokucwebezela kwephepha, futhi ithuthukise ukusebenza kokuphrinta kwephepha.
5. Imboni Yezinto Zobumba: Enqubweni yokukhiqiza imikhiqizo ye-ceramic, i-White Carbon Black isetshenziswa kabanzi ekulungiseleleni ama-glaze kanye nemizimba, okuthuthukisa amandla, ubulukhuni, kanye nokumelana nokuguguleka kwemikhiqizo ye-ceramic.
6. Imboni ye-Ink: Njengomgcwalisi we-pigment, i-White Carbon Black ingathuthukisa amandla okumboza, ukunamathela, kanye nokuqina kwama-ink, futhi ithuthukise ukusebenza kokuphrinta kwama-ink.
7. Imboni Yezimonyo: I-White Carbon Black, njenge-filler kanye ne-ejenti yokuqina, ingathuthukisa ubuncane, ukuzinza, kanye nomuzwa wezimonyo, ilawule ukukhishwa kwamafutha esikhumba, futhi ithuthukise ikhwalithi yesikhumba.
8. Imboni Yezemithi: I-White Carbon Black isetshenziswa kakhulu ekulungiseleleni amafomula emithi, ukuthuthukisa ukusabalala, ukuzinza, kanye nokutholakala kwemithi, kanye nokunciphisa imiphumela emibi.
