Chiyambi:

Kaboni wakuda woyera ndi mawu ofala a ufa woyera wa X-ray amorphous silicic acid ndi zinthu za silicate, makamaka kutanthauza silika wosungunuka, silika wofumira ndi gel ya silica yopyapyala kwambiri, komanso ufa wopangidwa ndi aluminiyamu silicate ndi calcium silicate. Kaboni wakuda woyera ndi chinthu chokhala ndi porous, ndipo kapangidwe kake kakhoza kuyimiridwa ndi SiO2 · nH2O, komwe nH2O ilipo mu mawonekedwe a magulu a hydroxyl pamwamba. Amasungunuka mu caustic soda ndi hydrofluoric acid, osasungunuka m'madzi, zosungunulira, ndi ma acid (kupatula hydrofluoric acid). Kukana kutentha kwambiri, kosayaka, kosanunkhira, kosanunkhira, komanso kutchinjiriza bwino magetsi.

CAS：10279-57-9

EINECS：238-878-4

Mawonekedwe: Ufa woyera kapena granular kapena mabuloko osawoneka bwino.

Kuchuluka: pafupifupi 2.0g/mL

Kukana kutentha kwambiri, kosayaka, komanso kutchinjiriza magetsi bwino.

Zosakaniza:

Kaboni wakuda woyera akhoza kugawidwa m'magulu awiri: wakuda woyera wopangidwa ndi mpweya ndi wakuda woyera wopangidwa ndi mpweya malinga ndi njira zopangira. Munthawi yachizolowezi, kaboni wakuda woyera wopangidwa ndi mpweya ndi mtundu woyera wa amorphous flocculent semi transparent solid colloidal nanoparticle (tinthu tating'onoting'ono tosakwana 100nm), wopanda poizoni, ndipo uli ndi malo akuluakulu apadera. Kaboni wakuda woyera wopangidwa ndi mpweya umapangidwa ndi nano silica, wokhala ndi chiyero cha 99% ndi kukula kwa tinthu tating'onoting'ono ta 10-20nm. Komabe, njira yokonzekera ndi yovuta komanso yokwera mtengo; Kaboni wakuda woyera wopangidwa ndi mpweya ukhoza kugawidwa m'magulu awiri: wakuda woyera wopangidwa ndi mpweya ndi wakuda wapadera wopangidwa ndi mpweya. Woyamba amatanthauza silicon dioxide yopangidwa ndi sulfuric acid, hydrochloric acid, CO2 ndi galasi lamadzi ngati zinthu zoyambira, ndipo womaliza amatanthauza silicon dioxide yopangidwa ndi njira zapadera monga ukadaulo wapamwamba, njira ya sol gel, njira ya kristalo ya mankhwala, njira yachiwiri yopangira makristalo kapena njira yosinthira ya micellar micro lotion. Silika yopangidwa ndi mpweya imagwiritsidwa ntchito makamaka ngati chothandizira cholimbitsa mphira wachilengedwe ndi rabara yopangidwa, komanso chothandizira kukangana kwa mano. Silika ya nthunzi imagwiritsidwa ntchito makamaka ngati chowonjezera mphamvu, chophimba ndi chokhuthala cha unsaturated resin cha rabara ya silicone, ndipo gel ya silica ndi airgel yopyapyala kwambiri imagwiritsidwa ntchito makamaka ngati chothandizira kuphimba, chokhuthala, chotsegulira filimu ya pulasitiki, ndi zina zotero. Monga chowonjezera choteteza chilengedwe komanso chogwira ntchito bwino, kaboni wakuda woyera umagwiritsidwa ntchito makamaka m'minda ya zinthu za rabara (kuphatikizapo rabara ya silikoni yotenthedwa kwambiri), nsalu, kupanga mapepala, mankhwala ophera tizilombo, ndi zowonjezera zakudya.

Kagwiritsidwe:

Zogulitsa za rabara

Kaboni wakuda woyera amagwiritsidwa ntchito mu zinthu za rabara zamitundu yosiyanasiyana kuti alowe m'malo mwa kaboni wakuda kuti awonjezere mphamvu, kukwaniritsa zosowa za zinthu zoyera kapena zowonekera pang'ono. Silika imakhalanso ndi mphamvu yolimba, yolimba, yolimba kutentha komanso yolimba, kotero imathanso kusintha gawo la kaboni wakuda mu zinthu za rabara zakuda kuti ipeze zinthu zapamwamba za rabara, monga matayala akunja kwa msewu, matayala aukadaulo, matayala a radial, ndi zina zotero.

Zinthu za tsiku ndi tsiku zopangidwa ndi mankhwala

Mankhwala otsukira mano okhala ndi mtundu wowonekera komanso wosawoneka bwino okhala ndi kaboni wakuda ngati chodzaza ndi chokwirira, chomwe chimakhala chosinthasintha komanso chosavuta kufalikira, phala losalala komanso lofewa, cholimba bwino pakukanda, ndipo sichiwononga thupi la chubu cha mano otsukira mano; Chingathe kusunga kukhazikika kwa mankhwala otsukira mano. Makamaka ngati chikugwirizana bwino ndi fluoride, chingapewe kuipitsa kwa mchere wosasungunuka wopangidwa ndi mchere wa calcium ngati chokwirira.

Wothandizira simenti

Pogwiritsidwa ntchito mu zomatira zopangidwa ndi rabala lachilengedwe kapena rabala lopangidwa, limapereka thixotropy ndi mphamvu, komanso limakulitsa kumatira chifukwa cha kulimba kwake, zomwe zimapangitsa kuti likhale lapamwamba komanso lotsika mtengo.

Woletsa kutsekeka

Kaboni wakuda woyera angagwiritsidwe ntchito pazinthu zina kuti awonjezere kusinthasintha kwa madzi, monga feteleza wa udzu, fungicides, grinding wheel abrasives, laundry bleach, phenolic injection molding ya urotropine, zinthu zapulasitiki za phenols ndi urea, kupanga rabara sulfure ndi zosakaniza zoletsa kukhetsa.

Kudzaza mapepala

Kugwiritsa ntchito kaboni wakuda woyera ngati chodzaza mapepala kungathandize kuti inki isagwedezeke komanso kuti pepala likhale lolimba, kuonjezera kuyera, komanso kuchepetsa kulemera kwa pepala. Kungathandize kuti pepala likhale lopepuka, kuchepetsa ndalama zopangira, komanso kukonza magwiridwe antchito a pepala.

Kuphatikiza apo, ingagwiritsidwenso ntchito m'mafakitale ambiri monga zozimitsa moto, chakudya, zodzoladzola, zozimitsa moto, utoto, ndi zina zotero.
