Silicon Dioxide (SiO₂) yog qhov thib ob muaj ntau tshaj plaws hauv cov av inorganic hauv lub ntiaj teb. Tom qab kev ntxuav thiab kev tsim kho, nws tau siv dav hauv cov ntaub ntawv siv hauv kev tsim kho, roj hmab, khoom siv hluav taws xob, tshuaj pleev ib ce thiab lwm yam, ua cov khoom siv tseem ceeb rau kev tsim khoom yooj yim thiab qib siab.

1. Cov txheej txheem tsim khoom (ob txoj kev)

（1)Txoj kev ntxuav cov ntxhia ntuj

Siv cov quartzite, quartz xuab zeb, diatomite ua cov khoom siv raw; tshem tawm Fe/Al impurities los ntawm kev sib tsoo, sib tsoo thiab flotation. SiO₂ purity ≥98.5%, pheej yig, tsim nyog rau cov ntaub ntawv siv hauv kev tsim kho, txheej thiab lwm yam kev siv dav dav.

(2)Txoj kev tsim tshuaj lom neeg

Siv silanes thiab silicates ua cov khoom siv raw; tsim los ntawm cov txheej txheem fumed / precipitation nrog AI tswj qhov kub thiab txias thiab lub tshuab nqus tsev. Purity txog li 99.9% +, qhov loj me ntawm cov khoom me me tuaj yeem tswj tau los ntawm nano mus rau micron. Zoo tagnrho rau cov khoom siv hluav taws xob, semiconductors, cov tshuaj pleev ib ce siab; suav txog ntau dua 60% ntawm kev ua lag luam siab..

2. Cov yam ntxwv tseem ceeb

（1） Kub thiab huab cua tsis kam, melting point ~ 1800 ℃, UV-resistant, tsis muaj kev laus lossis decomposition tom qab siv sab nraum zoov ntev

（2） Tus phooj ywg ib puag ncig & tsis muaj tshuaj lom, tsis muaj hlau hnyav, ua raws li EU REACH & RoHS; muaj kev nyab xeeb rau kev sib cuag zaub mov, cov khoom siv rau menyuam yaus, tshuaj pleev ib ce

（3）Kev txhawb zog & kev ua kom tawv, thaj chaw tshwj xeeb siab; txhim kho lub zog tensile los ntawm 30% -50% hauv roj hmab / yas

（4） Qhov nqus dej thiab kev tawg ua me me; siv ua tus neeg sawv cev matting, desiccant, tiv thaiv kev faib ua pawg thiab kev tso dej tawm

3. Kev lag luam thov

（1)Cov Khoom Siv Tsim Kho

Ua kom muaj zog tiv taus kev hnav hauv cov pob zeb / mortar; ua haujlwm ua tus neeg sawv cev / matting hauv cov txheej txheem / dej tsis kam kom txhawb kev lo rau thiab kev tiv thaiv huab cua.

（2)Roj Hmab thiab Yas

Ua kom cov log tsheb, cov foob, cov hlua khi ruaj khov; ua kom cov kav dej, cov khoom siv hluav taws xob, thiab cov khoom ntim khoom noj khoom haus ruaj khov thiab tiv taus cua sov. Muaj ntau tshaj 40% ntawm cov tuam txhab roj hmab loj yuav.

（3)Cov Tshuaj Pleev Xim thiab Cov Khoom Siv Uas Siv Tau Ntev

Nano-qib siv rau kev tswj roj & pleev qhov chaw; qib siab-melting-point rau cov cib refractory & abrasives hauv metallurgy & machining.

4. Cov Qauv Kev Yuav Khoom

Kev Tsim Nyog: ua raws li GB/T 30916-2014, ISO daim ntawv pov thawj; REACH/FDA rau kev xa tawm. Cov lus qhia tshwj xeeb: kev huv, qhov loj me ntawm cov khoom me me / thaj chaw tshwj xeeb, dej noo ≤1%, cov khoom seem ≤0.1%. Ua qhov kev sim sib xws me me ua ntej; muab qhov tseem ceeb rau cov neeg muag khoom uas tau kuaj xyuas nrog kev hloov kho & kev txhawb nqa kev pab cuam tom qab muag.
