Silicon Dioxide (SiO₂) ndi mchere wachiwiri wachilengedwe wochuluka kwambiri padziko lapansi. Pambuyo poyeretsa ndi kupanga, imagwiritsidwa ntchito kwambiri pazipangizo zomangira, rabara, zamagetsi, zodzoladzola ndi zina, zomwe zimagwiritsidwa ntchito ngati zinthu zofunika kwambiri popanga zinthu zoyambira komanso zapamwamba.

1. Njira zopangira (njira ziwiri)

()1）Njira yachilengedwe yoyeretsera mchere

Amagwiritsa ntchito quartzite, mchenga wa quartz, diatomite ngati zinthu zopangira; amachotsa zinyalala za Fe/Al kudzera mu kuphwanya, kupukuta ndi kuyandama. Kuyera kwa SiO₂ ≥98.5%, kotsika mtengo, koyenera kugwiritsidwa ntchito pa zinthu zomangira, zokutira ndi zina.

(2)Njira yopangira mankhwala

Imagwiritsa ntchito ma silane ndi ma silicate ngati zinthu zopangira; imapangidwa ndi njira yopumira/yopanda mpweya yokhala ndi kutentha kwa AI komanso yankho la vacuum. Yoyera mpaka 99.9%+, kukula kwa tinthu tomwe timatha kusinthidwa kuchokera ku nano mpaka micron. Yabwino kwambiri pa zamagetsi, ma semiconductor, zodzoladzola zapamwamba; imayimira zoposa 60% ya msika wapamwamba.。

2. Zinthu Zapakati

()1）Kukana kutentha kwambiri ndi nyengo, kutentha kosungunuka ~1800℃, kukana UV, kukalamba kapena kuwonongeka pambuyo pakugwiritsa ntchito panja kwa nthawi yayitali

()2）Yochezeka ku chilengedwe komanso yopanda poizoni, yopanda zitsulo zolemera, yogwirizana ndi EU REACH & RoHS; yotetezeka pokhudzana ndi chakudya, zinthu za ana, zodzoladzola

()3Kulimbitsa ndi kulimbitsa, malo apadera; kumawonjezera mphamvu yokoka ndi 30%–50% mu rabara/pulasitiki

()4） Kuthira madzi m'mabowo ndi kufalikira; imagwiritsidwa ntchito ngati chothandizira kukumbatira, chotsukira madzi, choletsa kupangika kwa nthaka ndi kusungunuka kwa nthaka

3.Mafakitale ogwiritsira ntchito

()1）Zipangizo Zomangira

Imalimbitsa kukana kuwonongeka mu konkire/matope; imagwira ntchito ngati chodzaza/chothandizira pakuphimba/kuteteza madzi kuti iwonjezere kumatirira komanso kupirira nyengo.

()2）Rabala ndi Mapulasitiki

Imalimbitsa matayala, zomangira, zitseko za chingwe; imawonjezera kulimba ndi kukana kutentha m'mapaipi, m'zipinda za zida, komanso m'mabokosi a chakudya. Imagulidwa ndi makampani otsogola opitilira 40%.

()3）Zodzoladzola ndi Zotsitsimula

Gulu la nano-grade lomwe limagwiritsidwa ntchito powongolera mafuta ndi kukonza zodzoladzola; gulu lapamwamba kwambiri losungunuka la njerwa zosasunthika komanso zopukutira mu metallurgy ndi makina.

4. Miyezo Yogulira Zinthu

Ziyeneretso: kutsatira GB/T 30916-2014, satifiketi ya ISO; REACH/FDA yotumizira kunja. Mafotokozedwe: kuyera, kukula kwa tinthu/malo enaake, chinyezi ≤1%, zotsalira ≤0.1%. Chitani mayeso ang'onoang'ono ogwirizana poyamba; perekani patsogolo ogulitsa owunikidwa ndi kusintha kwa zinthu ndi chithandizo chaukadaulo pambuyo pogulitsa.
