iindaba

I-carbon black emhlophe (i-silica dioxide) yahlulwe ngokwe-silica efumileyo (isigaba somphunga) kunye ne-silica ekhawulezileyo (isigaba solwelo), nganye ineempawu zayo ezahlukeneyo kunye namacala okusetyenziswa.

I-Silica evuthayo

I-silica efumileyo, eveliswa yi-hydrolysis yobushushu obuphezulu ye-chlorosilanes kwilangatye le-hydrogen-oxygen, iqhayisa ngobumsulwa obuyi-≥99.8%, ii-nanoscale primary particles (7–40 nm), kunye nommandla ophezulu kakhulu (100–400 m²/g). Yenza iinethiwekhi ze-thixotropic eziqinileyo, inikezela ngokuqina okugqwesileyo, uzinzo lobushushu, kunye nokufakelwa kombane. Ilungele ukusetyenziswa okuphezulu, isebenza njengearhente yokuqinisa ebalulekileyo kwiirabha ze-silicone, i-rheology modifier kwiingubo/izincamathelisi ukuthintela ukugoba, kunye nesongezelelo esibalulekileyo kwiicosmetics, ii-encapsulants ze-elektroniki, kunye nezixhobo zebhetri.

I-Silica evuthulukileyo

I-silica evuthulukileyo, eyenziwe ngokuthomalalisa i-sodium silicate nge-asidi (umz., i-H₂SO₄) elandelwa yimvula kunye nokomisa, inobunyulu obumalunga ne-93%, amasuntswana amakhulu ahlanganisiweyo (isikali se-micron), kunye nommandla ophakathi othile (100–200 m²/g). Ixabiso layo liphantsi kwaye kulula ukuyicubungula, igqwesile kwiimeko ezinobunkunkqele beendleko. Isetyenziswa kakhulu njengesizalisi sokuqinisa kwiitayara (ukunciphisa ukumelana nokuqengqeleka) kunye neemveliso zerabha, i-agent yokumathisa kwiipeyinti, i-agent yokungqubana kwi-toothpaste, kunye ne-agent yokuthwala/yokulwa nokugabha kwiizongezo zokutya nezokutya.

Umahluko oPhambili: Ukusebenza kunye neendleko

Umahluko ophambili usekwe ekusebenzeni nakwixabiso:i-silica evuthayoinika amandla aphezulu kunye nozinzo kwizicelo ezisebenza kakuhle ngexabiso eliphezulu, ngelixai-silica ekhawulezileyoInika ukusebenza okuthembekileyo ngexabiso eliphantsi kwiimfuno zenjongo ngokubanzi. Ukukhetha uhlobo olufanelekileyo kuphucula ukusebenza kwezinto, kulinganisela iindleko, kwaye kuhambelana neemfuno ezithile zesicelo.

Eli nqaku linika umbono ocacileyo ukukunceda ukhethe i-silica efanelekileyo kwiiprojekthi zakho.
