izindaba

I-carbon black emhlophe (i-silica dioxide) ihlukaniswe nge-silica evuthayo (isigaba somhwamuko) kanye ne-silica evuvukele (isigaba soketshezi), ngayinye inezakhiwo ezihlukile kanye namacala okusetshenziswa.

I-Silica Efuthwe

I-silica efumile, ekhiqizwa nge-hydrolysis ephezulu yama-chlorosilanes elangeni le-hydrogen-oxygen, igcwele ubumsulwa obungu-≥99.8%, izinhlayiya eziyinhloko ze-nanoscale (7–40 nm), kanye nendawo ephezulu kakhulu (100–400 m²/g). Yakha amanethiwekhi aqinile e-thixotropic, inikeza ukuqinisa okumangalisayo, ukuzinza kokushisa, kanye nokufakwa kokushisa kagesi. Ilungele ukusetshenziswa okuphezulu, isebenza njenge-ejenti ebalulekile yokuqinisa kuma-silicone rubber, i-rheology modifier kuma-coating/adhesives ukuvimbela ukugoba, kanye nesengezo esibalulekile kuma-cosmetics, ama-encapsulants kagesi, kanye nezinto zebhethri.

I-Silica Enezimvula

I-silica evundile, ekhiqizwa ngokususa i-sodium silicate nge-asidi (isb., i-H₂SO₄) elandelwa ukuna kwemvula nokomisa, inezici zobumsulwa ezicishe zibe ngu-93%, izinhlayiya ezinkulu ezihlanganisiwe (isikali se-micron), kanye nendawo ethile ephakathi nendawo (100–200 m²/g). Isebenza kahle futhi kulula ukuyicubungula, iphumelela kakhulu ezimweni ezibucayi kakhulu. Isetshenziswa kabanzi njengesigcwalisi sokuqinisa amathayi (ukunciphisa ukumelana nokugoqa) kanye nemikhiqizo yerabha, i-ejenti yokumboza opende, i-ejenti yokungqubuzana ku-toothpaste, kanye ne-ejenti yokuthwala/yokulwa nokubopha ezithasiselweni zokudla nokondla.

I-Silica Efuthwe (Isigaba Sokuhwamuka)

  • Ukukhiqizwa:I-hydrolysis ephezulu ye-chlorosilanes elangeni le-H–O2
  • Ubumsulwa:≥99.8%
  • Usayizi Wezinhlayiya:7–40 nm (izinhlayiya eziyinhloko ze-nanoscale)
  • Indawo Ekhethekile Yomphezulu:100–400 m²/g
  • Izakhiwo Eziyinhloko:Amanethiwekhi e-Thixotropic, ukuqinisa okumangalisayo, ukuzinza kokushisa, ukuvikela ugesi
  • Izicelo:Amarabha e-silicone, izembozo/izinamathiselo (ezivimbela ukugoba), izimonyo, izinto zokufaka izinto zikagesi, izinto zebhethri

I-Silica Enezimvula (Isigaba Soketshezi)

  • Ukukhiqizwa:Ukunciphisa i-sodium silicate nge-asidi (isb., H₂SO₄), imvula kanye nokomisa
  • Ubumsulwa:~93%
  • Usayizi Wezinhlayiya:Isikali se-Micron (esihlanganisiwe)
  • Indawo Ekhethekile Yomphezulu:100–200 m²/g
  • Izakhiwo Eziyinhloko:Kusebenza kahle, kulula ukukucubungula, futhi kuthembekile
  • Izicelo:Amathayi (ukunciphisa ukumelana nokugoqa), imikhiqizo yerabha, i-ejenti yokumboza ngopende, i-ejenti yokungqubuzana kwamazinyo, i-ejenti yokudla nokondla/i-ejenti yokulwa nokugebha

Umehluko Omkhulu: Ukusebenza vs. Izindleko

Umehluko oyinhloko usekusebenzeni kanye nezindleko:i-silica evuthayoinikeza amandla aphezulu kanye nokuqina kwezinhlelo zokusebenza ezisebenza kahle ngentengo ephezulu, kuyilaphoi-silica evukileinikeza ukusebenza okuthembekile ngentengo ephansi yezidingo zenhloso ejwayelekile. Ukukhetha uhlobo olufanele kuthuthukisa ukusebenza kwezinto ezibonakalayo, kulinganisela izindleko, futhi kuhambisana nezidingo ezithile zohlelo lokusebenza.

Lesi sihloko sinikeza umbono ocacile ukukusiza ukhethe i-silica efaneleke kakhulu kumaphrojekthi akho.
