Ukwakheka kweekhemikhali
Okokuqala, kufuneka sicacise ukuba i-white carbon black kunye ne-silicon dioxide zinokwakheka okufanayo kweekhemikhali, kwaye ifomula yazo yeekhemikhali yi-SiO ₂. I-white carbon black ngokwenene luhlobo oluthile lwe-silica, kwaye ukwakheka kwayo kunokumelwa yi-SiO2 · nH2O, apho i-nH2O ikhona kwimo yamaqela e-surface hydroxyl.
Inkangeleko kunye neempawu
Ngokwembonakalo kunye neempawu, i-white carbon black kunye ne-silica nazo zahlukile. Imbonakalo ye-silica yi-amorphous white powder, ayinatyhefu, ayinavumba, kwaye ayinangcoliseko. Isakhiwo sayo esincinci singqukuva, siyashukuma, kwaye sifana nenethiwekhi, asinyibiliki emanzini. Imbonakalo ye-white carbon black, kwelinye icala, yi-white powder, inemilo engqukuva okanye engacwangciswanga, inyibilika kwi-caustic soda kunye ne-hydrofluoric acid, ayinyibiliki emanzini, kwi-solvents, nakwi-asidi (ngaphandle kwe-hydrofluoric acid), kwaye ineempawu zokumelana nobushushu obuphezulu, ukungatshi, ukungavuthi, ukungavuthi, kunye nokufakelwa kombane okuhle.
indawo yesicelo
Ngokuphathelele ukusetyenziswa, i-white carbon black kunye ne-silica nazo zineempawu zazo. I-Silicon dioxide sisixhobo esibalulekileyo esisetyenziswa kakhulu ekuvelisweni kweglasi, iglasi ye-quartz, i-sodium silicate, iifayibha ze-optical, izinto ezibalulekileyo kushishino lwe-elektroniki, izixhobo ze-optical, imisebenzi yezandla, kunye nezinto ezichaseneyo. I-white carbon black isetyenziswa kakhulu kwiimveliso zerabha, iikhemikhali zezolimo, iimveliso zeekhemikhali zemihla ngemihla, iiplastiki, ii-coating, ii-resin composites, kunye ne-paper fillers. Ukongeza, i-white carbon black isetyenziswa kakhulu endaweni ye-carbon black kwiimveliso zerabha.
Indlela yokulungiselela
Ngokweendlela zokulungiselela, umnyama wekhabhoni emhlophe kunye nesilika nazo zahlukile. Umnyama wekhabhoni emhlophe ungalungiswa ngeendlela zokuna kwemvula okanye zegesi, kwaye iindlela ezahlukeneyo zokulungiselela ziphumela kwiimveliso ezimbini ezahlukeneyo ezinefomula efanayo yemolekyuli.
Iimpawu zokusebenza
Ngokweempawu zokusebenza, kukwakho umahluko phakathi komnyama wekhabhoni emhlophe kunye nesilika. Umnyama wekhabhoni emhlophe yinto eneembobo, enesimo se-aggregate kunye nesakhiwo esifana nesikamnyama wekhabhoni. Kwelinye icala, i-nano silica yinto emhlophe engenabungozi, engenavumba, kwaye engenangcoliseko engenazo izinto ezimdaka ezimhlophe ezingenasinyithi ezinobukhulu obuncinci besuntswana (0-100nm) kunye nommandla omkhulu womphezulu. Ineempawu zokubonakalisa ezinamandla kakhulu ze-ultraviolet, infrared, kunye nokukhanya okubonakalayo. Isiphumo somthamo kunye nesiphumo se-quantum tunneling se-nano silica zibangela ukuba ibe nesiphumo se-percolation, esinokwenza isakhiwo senethiwekhi yendawo kunye neekhompawundi ze-organic molecular, nto leyo ephucula kakhulu amandla oomatshini, ukuqina, ukumelana nokuguguleka, kunye nokumelana nokuguga kwezinto zepolymer.
Ngamafutshane, nangona i-white carbon black kunye ne-silica zinokwakheka okufanayo kweekhemikhali, zahlukile ngenkangeleko, iimpawu, iindawo zokusetyenziswa, kunye neendlela zokulungiselela.
