Yus li cas White Carbon Black? Qhov ntaub ntawv silica tshaj xav uas pab tau cov kev lag luam tshaj xav

Ua tsaug rau qhov cim tshwj xeeb ntawm cov khoom siv hauv qhov kev tsim kho tshaj plij , daim duab cua ntawm qhov cua dawb yog qhov lus sib txuas rau cov duab cua dawb uas muaj duab cua x-ray tsis muaj duab thiab cov duab cua silicic acid thiab silicate, uas tseem ceeb tshaj plaws yog hydrated silicon dioxide (SiO₂·nH₂O). Nws tau muab faib ua ob qhov: precipitated silica thiab fumed silica raws li nws txoj kev tsim. Nws muaj qhov duab nano-micron uas muaj qhov khoob thiab muaj qhov zoo tshaj plaws ntawm kev ua haujlwm thiab kev ua haujlwm ntawm qhov duab. Tshiab no, nws tau dhau los yog qhov tswv yim tshaj plaws uas tsis tuaj yeem siv dua rau hauv qhov kev sib tw ntau yam, ib yam li rubber, lub roj, cov duab cua, thiab cov khoom siv hauv tsev.


1. Qhov kev tsim ntawm White Carbon Black: Qhov kev tsim ntawm ob qhov kev tsim tshwj xeeb

White carbon black yog ib qho khoom siv inorganic synthetic tsis muaj thawj, thiab nws kev tsim kho tshwj xeeb yog qhov uas xaiv nws qhov cuab yeej thiab qhov chaw uas nws tuaj yeem siv. Kev tsim cov khoom siv white carbon black zoo tshaj plaws yog nyob ntawm kev xaiv ntau yam kev xaiv ntawm kev ua haujlwm thiab kev tsim kho tshiab, thiab muaj ob qho kev tsim kho uas siv tau hauv tsev uas muaj qhov kev sib txuas thiab qhov kev sib txuas ntawm cov khoom siv uas muaj qhov sib txuas.

Precipitated silica

Nws yog qhia los ntawm kev sib koom ntawm cov ntaub ntawv hauv dej thiab sulfuric acid, hydrochloric acid, lossis carbon dioxide, tom qab ntawd muaj kev txhim kho ntau yam uas muaj kev tshuav, kev sov, kev hlau, kev saum, thiab kev tshuav. Qhov kev tsim no yuav tsum muaj kev xam ntau yam tswv yim uas muaj qhov tseem ceeb rau kev sib koom (28~32℃), pH value (5~7), thiab sijh hauv kev tshuav. Yog li cas, nws yog qhov white carbon black uas siv dav tshaj plaws, uas muaj ntau dua 80% ntawm qhov market share ntawm lub ntiaj teb, muaj qhov cost ntawm kev tsim thiab qhov performance uas tuaj yeem siv rau ntau yam hauv qab hauv kev sib koom thiab kev sib koom tshwj xeeb.

Fumed silica

Yeej hu ua 'pyrogenic silica' los, nws yog tsim los ntawm 'chemical vapor deposition' (CVD) technology. Nrog silicon tetrachloride, oxygen, thiab hydrogen ua cov khoom siv rau hais, nws dhau los ntawm 'high-temperature gas-phase hydrolysis' nyob rau hauv 1000~1800℃ kom muaj cov particles amorphous flocculent nyob rau hauv nano-scale (10~20nm nyob rau hauv particle size). Cov khoom no muaj 'ultra-high purity' (txog 99.9%) thiab 'enormous specific surface area'. Tsis tas li qhov kev tsim no yuav tsum muaj kev sib txuas ntau thiab qhov cost ntawm kev tsim no yog siab dua, tab sis nws yog cov khoom siv tseem ceeb rau kev tsim khoom tseem ceeb nyob rau hauv qhov chaw tsim khoom tseem ceeb uas muaj kev ua haujlwm zoo heev.

Ntawm lwm yam, cov kev tsim tshiab uas siv cov khoob tshuaj tsis muaj looj hauv (non-metallic minerals) los ntawm kaolin, coal gangue, thiab fly ash ua rau cov khoom sib tw (silicon sources) tau txhawj nqa mus rau hauv qhov kev tsim tshiab. Cov kev tsim no tsis yog tso cia rau kev txhawj nqa siab dua li kev tsim tshiab lawm, tab sis kuj pab txhawj nqa cov khoom uas tau siv lawm (resource recycling) kom tau siv dua, thiab tau dhau los yog qhov kev pib tshiab rau qhov kev tsim tshiab ntawm white carbon black.
