Mpweya Woyera Wakuda

Kaboni Wakuda Woyera, womwe umadziwikanso kuti silica yosungunuka kapena silica yopepuka, yokhala ndi dzina la mankhwala la silicon dioxide (SiO₂), ndi ufa woyera, wopanda poizoni, komanso wosapanga mawonekedwe a nanometer. Dzina lake limatengera mawonekedwe ake oyera komanso kuthekera kwake kogwira ntchito m'malo mwa wakuda wa kaboni.

I. Chidziwitso Choyambira

• Mawonekedwe: Ufa woyera kapena granular kapena mabuloko osawoneka bwino.
• Kapangidwe ka Mankhwala: Sungunuka mu caustic alkalis ndi hydrofluoric acid, osasungunuka m'madzi, zosungunulira, ndi ma acid (kupatula hydrofluoric acid).
• Kapangidwe kake: Kulimba kutentha kwambiri, kosayaka moto, kopanda kukoma, kopanda fungo, kokhala ndi kutchinjiriza kwamagetsi kwabwino kwambiri.
• Nambala ya CAS: 10279-57-9
• Nambala ya EINECS: 238-878-4

II. Zigawo Zazikulu ndi Kapangidwe kake

Gawo lalikulu la White Carbon Black ndi silicon dioxide, yomwe ikhoza kuyimiridwa ndi fomula ya SiO₂·nH₂O, pomwe nH₂O ilipo mu mawonekedwe a magulu a hydroxyl pamwamba. White Carbon Black ndi chinthu chokhala ndi mapokoso chokhala ndi malo akuluakulu komanso ntchito yapamwamba.

III. Njira Zokonzekera

Njira zokonzekera White Carbon Black zimaphatikizapo njira ya gasi, njira ya mvula, ndi njira yowola.

• Njira Yogwiritsira Ntchito Mpweya: Pogwiritsa ntchito silicon chloride (monga silicon tetrachloride) ngati zopangira, White Carbon Black imapangidwa kudzera mu hydrolysis ya moto pa kutentha kwambiri. Gas-phase White Carbon Black ili ndi ubwino wa tinthu tating'onoting'ono, malo akuluakulu, komanso kuyera kwambiri kwa mankhwala, koma njira yokonzekera ndi yovuta ndipo mtengo wake ndi wokwera.
• Njira Yopezera Mpweya: Mpweya wa silicon dioxide umapangidwa pochita zinthu ndi sodium silicate ndi asidi, kenako Mpweya Woyera Wakuda umapezeka kudzera mu kusefa, kutsuka, kuumitsa, ndi njira zina. Ukadaulo wopanga mpweya wa mpweya wa White Carbon Black ndi wokhwima, ndipo zipangizo zake ndi zosavuta, koma chinthucho chili ndi ntchito yochepa ndipo tinthu tating'onoting'ono n'tovuta kulamulira.

IV. Madera Ogwiritsira Ntchito

Kaboni Yoyera ya Carbon Black imagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana chifukwa cha mawonekedwe ake apadera:

1. Makampani Opanga Raba: Kaboni Yoyera Yakuda ndi chinthu chofunikira kwambiri chothandizira zinthu za raba, chomwe chingathandize kulimbitsa mphamvu, kukana kuwonongeka, kukana kung'ambika, komanso kuteteza kukalamba kwa zinthu za raba. Imagwiritsidwa ntchito kwambiri popanga matayala, chifukwa imatha kuwonjezera kugwira matayala ndikuwonjezera chitetezo choyendetsa.
2. Makampani Opanga Mapulasitiki: Monga chowonjezera mphamvu ndi chodzaza, White Carbon Black imatha kusintha kwambiri mphamvu, kuuma, ndi kukana kuwonongeka kwa mapulasitiki, ndikuwonjezera magwiridwe antchito a mapulasitiki.
3. Makampani Opangira Zophimba: Kaboni Yoyera Yakuda, monga chodzaza utoto, imatha kuwonjezera mphamvu yophimba, kumatira, komanso kukana kwa zophimba nyengo, ndikuchepetsa ndalama zophimba.
4. Makampani Opanga Mapepala: Monga chodzaza chapamwamba kwambiri, White Carbon Black imatha kuyeretsa, kusalala, ndi kunyezimira kwa mapepala, komanso kukonza magwiridwe antchito osindikiza mapepala.
5. Makampani Opanga Zoumba: Pakupanga zinthu zadongo, White Carbon Black imagwiritsidwa ntchito kwambiri popanga magalasi ndi matupi, zomwe zimapangitsa kuti zinthu zadongo zikhale zolimba, zolimba, komanso zolimba.
6. Makampani Opanga Inki: Monga chodzaza utoto, White Carbon Black imatha kukonza mphamvu yophimba, kumatira, komanso kukhazikika kwa inki, komanso kukonza magwiridwe antchito osindikiza a inki.
7. Makampani Ogulitsa Zodzoladzola: Kaboni Yoyera Yakuda, monga chodzaza ndi chokhuthala, imatha kukonza kusalala, kukhazikika, ndi kumva kwa zodzoladzola, kuwongolera kutulutsa mafuta pakhungu, ndikukweza mtundu wa khungu.
8. Makampani Opanga Mankhwala: Kaboni Yoyera ya Carbon Black imagwiritsidwa ntchito kwambiri popanga mankhwala, kukonza kufalikira, kukhazikika, komanso kupezeka kwa mankhwala, komanso kuchepetsa zotsatirapo zake.
