Ikhabhoni emhlophe emnyama

I-White Carbon Black, eyaziwa ngokuba yi-hydrated silica okanye i-light silica, enegama lekhemikhali elithi silicon dioxide (SiO₂), yi-white, non-toxic, amorphous nanometer-scale powder. Ithiywe ngembonakalo yayo emhlophe kunye nokukwazi kwayo ukusebenza endaweni ye-carbon black.

I. Ulwazi oluSisiseko

• Inkangeleko: Umgubo omhlophe okanye iibhloko ezibunjiweyo okanye ezimile ngendlela engaqhelekanga.
• Iipropati zeKhemikhali: Inyibilika kwi-caustic alkalis kunye ne-hydrofluoric acid, ayinyibiliki emanzini, kwizinyibilikisi, nakwii-asidi (ngaphandle kwe-hydrofluoric acid).
• Iimpawu Zomzimba: Ukumelana nobushushu obuphezulu, akutshi, akunancasa, akunavumba, kwaye kugqunywe umbane ogqwesileyo.
• Inombolo ye-CAS: 10279-57-9
• Inombolo ye-EINECS: 238-878-4

II. Izinto eziphambili kunye nolwakhiwo

Eyona nto iphambili kwiWhite Carbon Black yisilicon dioxide, enokumelwa yifomula iSiO₂·nH₂O, apho i-nH₂O ikhona ngohlobo lwamaqela e-surface hydroxyl. IWhite Carbon Black yinto eneembobo enendawo enkulu ethile yomphezulu kunye nomsebenzi womphezulu.

III. Iindlela Zokulungiselela

Iindlela zokulungiselela iWhite Carbon Black ziquka indlela yegesi, indlela yokukhupha imvula, kunye nendlela yokubola.

• Indlela yeGas-phase: Ukusebenzisa iisilicon chloride (ezifana nesilicon tetrachloride) njengezinto eziluhlaza, iWhite Carbon Black iveliswa yi-flame hydrolysis kumaqondo obushushu aphezulu. IGas-phase White Carbon Black ineengenelo zobukhulu obuncinci beesuntswana, indawo enkulu ethile, kunye nobunyulu obuphezulu beekhemikhali, kodwa inkqubo yokulungiselela iyinkimbinkimbi kwaye iindleko ziphezulu.
• Indlela Yokunisela: I-silicon dioxide precipitate iveliswa ngokuphendula i-sodium silicate kunye ne-asidi, ize emva koko i-White Carbon Black ifunyanwe ngokuhluza, ukuhlamba, ukomisa, kunye nezinye iinkqubo. Itekhnoloji yokuvelisa imvula I-White Carbon Black ivuthiwe, kwaye izixhobo zilula, kodwa imveliso inomsebenzi omncinci kwaye amasuntswana kunzima ukuwalawula.

IV. Iindawo zokusetyenziswa

I-White Carbon Black isetyenziswa kakhulu kwiindawo ezahlukeneyo ngenxa yeempawu zayo ezikhethekileyo:
