Hauv kev lag luam xws li roj hmab, plastics, coatings, adhesives, thiab silicone roj hmab, silica yog ib qho ntawm cov khoom siv ntau tshaj plaws. Txawm li cas los xij, ntau tus thawj tswj hwm kev yuav khoom thiab cov kws tsim khoom lag luam feem ntau pom tias nws nyuaj rau kev paub qhov txawvPrecipitated SilicathiabFumed Silica. Txawm hais tias ob qho tib si feem ntau hu uaDawb Carbon Dub, lawv txawv heev nyob rau hauv cov txheej txheem tsim, particle qauv, lub cev muaj zog, thiab kawg - siv daim ntawv thov.

Yog li, hom twg yog qhov kev xaiv zoo dua rau koj cov qauv?

Kab lus no muab kev qhia davSilica kev sib piv, npog cov txheej txheem tsim, particle loj, thaj chaw tshwj xeeb, dispersibility, nqi, thiab daim ntawv thov kev ua haujlwm. Txawm hais tias koj tab tom tsim cov khoom tshiab lossis cov khoom siv raw, phau ntawv qhia no yuav pab koj xaiv cov silica uas haum rau koj cov kev xav tau tshwj xeeb.

"White Carbon Black" yog cov lus siv dav dav siv los piav txog cov khoom lag luam amorphous silica. Nws tsis yog ib qho khoom siv nkaus xwb tab sis tsev neeg ntawm cov khoom siv hluavtaws uas suav nrog cov silica precipitated, fumed silica, silica gel, thiab lwm yam tshwj xeeb silica.

Ntawm lawv, ob hom kev siv ntau tshaj plaws yog:

• Precipitated Silica (325-Mesh)
• Fumed Silica (1250-Mesh)

Txawm hais tias ob qho tib si muaj feem ntau ntawm silicon dioxide (SiO₂), lawv cov txheej txheem ntau lawm tsim cov qauv sib txawv heev, ua rau muaj qhov sib txawv ntawm lub cev thiab tshuaj lom neeg.

Cov txheej txheem tsim khoom yog qhov sib txawv loj tshaj ntawm cov khoom siv silica no thiab feem ntau txiav txim siab lawv qhov kev ua tau zoo.

Precipitated Silica

Precipitated silica yog tsim los ntawm cov txheej txheem ntub dej uas sodium silicate reacts nrog ntxhia acids. Tom qab ntawd lub resulting silica precipitate yog lim, ntxuav, qhuav, thiab milled rau hauv hmoov.

Qhov no mature thiab scalable txheej txheem muaj zoo heev ntau lawm efficiency thiab nqi zoo, uaPrecipitated Silicaqhov nyiam reinforcing muab tub lim hauv ntau daim ntawv thov kev lag luam.

Nws cov txiaj ntsig tseem ceeb suav nrog:

• Mature ntau lawm technology
• Loj - muaj peev xwm tsim khoom
• Cov khoom zoo ib yam
• Ntau yam ntawm cov qib muaj

Fumed Silica

Fumed silica yog tsim los ntawm nplaim hydrolysis ntawm silicon tetrachloride (SiCl₄) ntawm qhov kub thiab txias.

Tsis zoo li precipitated silica, cov txheej txheem no tshwm sim tag nrho nyob rau hauv cov roj theem, ua ultra- zoo, siab - purity silica hais nrog ib tug tshwj xeeb peb - seem saw - zoo li cov qauv.

Vim tias nws cov txheej txheem ntau lawm thiab kev siv zog siab, fumed silica feem ntau kim dua li cov silica precipitated.

Txawm hais tias ob qho tib si cov khoom raug cais raws li ultra-silica zoo, lawv cov particle morphology txawv heev.

Precipitated Silica

• Qhov loj me me feem ntau yog nyob ntawm 10-50 nm
• Ua porous aggregates
• Loj dua theem nrab particle qauv
• Siab dua pore ntim

Fumed Silica

• Qhov loj me me feem ntau yog nyob ntawm 7-40 nm
• Highly uniform nano-sized particles
• Branched chain-zoo li cov qauv sib sau
• Muaj peev xwm thickening zoo heev

Cov qauv tshwj xeeb no muab fumed silica zoo tshaj plaws rheological thiab tiv thaiv -tawm cov khoom.

Cov cheeb tsam tshwj xeeb ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa kev ua tau zoo thiab muaj peev xwm adsorption.

Tej thaj chaw BET ntog yog:

Precipitated Silica

• Kwv yees li 50-250 m² / g
• Ntau qib muaj rau kev siv sib txawv

Fumed Silica

• Kwv yees li 90-400 m² / g
• Qee cov qib tshwj xeeb tshaj 400 m² / g

Ib qhov chaw siab dua feem ntau txhim kho cov thickening efficiency thiab kev ua tau zoo, tab sis nws tuaj yeem ua rau kom cov formulation complexity thiab sib tov nyuaj.

Ib qho ntawm cov lus nug ntau tshaj plaws los ntawm cov neeg siv khoom yog:

Uas silica disperses zoo dua?

Cov lus teb feem ntau nyob ntawm daim ntawv thov.

Precipitated silica, tshwj xeeb tshaj yog saum npoo- kho cov qib, feem ntau disperses yooj yim dua nyob rau hauv cov roj hmab tebchaw thiab thermoplastics, ua rau nws haum rau siab - ntim industrial ntau lawm.

Fumed silica, vim nws cov khoom zoo heev thiab thaj chaw loj, zoo li tsim cov agglomerates thiab feem ntau yuav tsum muaj siab - shear mixing equipment kom raug dispersion.

Txawm li cas los xij, ib zaug tag nrho dispersed, nws muab kev ua tau zoo tshaj plaws hauv cov tshuab pob tshab, silicone elastomers, sealants, thiab high -coatings kawg.

Rau feem ntau manufacturers, tus nqi tsim khoom yog qhov tseem ceeb rau kev txiav txim siab.

Precipitated Silica

• Tsawg tus nqi raw khoom
• Mature manufacturing txheej txheem
• Tus nqi zoo heev -kev ua tau zoo piv
• Zoo tagnrho rau loj -scale industrial ntau lawm

Fumed Silica

• Cov nqi tsim khoom siab dua
• Ntau zog- ntau lawm
• Tus nqi lag luam ntau dua

Tshwj tsis yog tshwj xeeb pob tshab, rheology tswj, los yog ultra- siab purity yuav tsum tau, ntau manufacturers nyiam precipitated silica vim hais tias nws muab kev ua tau zoo ntawm tus nqi qis dua.

Kev lag luam roj hmab tseem yog kev lag luam loj tshaj plaws rauPrecipitated Silica.

Nrog kev loj hlob sai ntawm ntsuab log tsheb technology,High Dispersion Precipitated Silicatau dhau los ua ib qho ntawm cov khoom tseem ceeb tshaj plaws hauv kev tsim cov log tsheb niaj hnub.

Los ntawm kev sib piv, fumed silica feem ntau yog siv hauv silicone roj hmab, tshwj xeeb sealants, thiab cov khoom siv hluav taws xob.

Rau coatings thiab adhesives, kev xaiv nyob ntawm ntau yam ntawm cov khoom xav tau kev ua tau zoo.

Thaum lub formulation xav tau:

• Kev tiv thaiv - thaj chaw
• Sag kuj
• Thixotropy
• Rheology tswj

Fumed silica feem ntau yog qhov kev xaiv zoo tshaj plaws.

Txawm li cas los xij, rau architectural coatings, industrial coatings, thiab hmoov txheej, hloov kho precipitated silica tuaj yeem xa cov kev ua tau zoo heev thaum txo cov nqi tsim khoom.
