Whai muri i te whakamaaramatanga o te kauwhata whakawhanui ki te pāmahana teitei, ka rite te tauine ki te kutukutu, a ka taea e te rōrahi te whakawhānui 100-400 wa. Ko tenei kauwhata whakawhanui kei te pupuri tonu i nga ahuatanga o te kauwhata maori, he pai te whakawhanui, he wetekina me te maiengi, he atete ki te pāmahana i raro i nga tikanga aukati hāora. Awhe whanui, ka taea i waenga i te -200 ~ 3000 ℃, ka mau tonu nga ahuatanga matū i raro i te pāmahana teitei, te pehanga teitei, nga tikanga radiation ranei, i roto i te hihiko me te hiri o te hinu, te matū, te hiko, te rererangi, te motuka, te kaipuke me nga ahumahi taputapu. te whānuitanga o nga tono. Ko nga kaiwhakatikatika o Furuit Graphite e whai ake nei ka maarama koe ki nga tikanga whakaputa noa o te kauwhata whakawhanui:
1. Ultrasonic oxidation tikanga ki te hanga graphite whakawhänui.
I roto i te faanahoraa no te faaineineraa i te graphite e nehenehe e faarahihia, e ravehia te vibration ultrasonic i nia i te electrolyte anodized, e te taime no te vibration ultrasonic te hoê â huru i to te anodization. Mai i te wiri o te electrolyte e te ngaru ultrasonic he painga ki te polarization o te cathode me te anode, ka whakaterehia te tere o te waiora anodic me te poto o te wa whakapouri;
2. Ko te tikanga tote whakarewa he kauwhata whakawhanui.
Whakaranuhia etahi whakaurunga ki te kauwhata me te wera hei hanga kauwhata whakawhanui;
3. Ka whakamahia te tikanga whakamaarama hau-waahanga hei hanga kauwhata whakawhanui.
Ko te graphite me te rauemi intercalated ka kawea mai ki nga pito e rua o te ngongo hiri korehau, ka whakamahana i te pito o te rauemi intercaled, a ko te rereketanga o te pehanga tauhohenga e tika ana ka hangaia e te rereketanga o te pāmahana i waenga i nga pito e rua, na te mea kua whakahiatotia. ka uru ki te paparanga kauwhata tawerewere i roto i te ahua o nga ngota ngota iti, na reira ka rite te kauwhata whakawhanui. Ka taea te whakahaere i te maha o nga paparanga o te kauwhata whakawhanui e mahia ana e tenei tikanga, engari he nui te utu o te whakaputanga;
4. Ko te tikanga whakawhitiwhiti matū ka taea te whakawhanui kauwhata.
Ko te rauemi mata tuatahi mo te whakareri ko te kauwhata tawerewere waro teitei, me etahi atu reagents matū penei i te waikawa pungatara (i runga ake i te 98%), hauwai peroxide (i runga ake i te 28%), pāhare pāporo, aha atu he reagents reagents ahumahi katoa. E whai ake nei nga mahi whakareri: i te pāmahana e tika ana, ka tauhohehia te wairewa hauwai peroxide, te kauwhata tawerewere me te waikawa pungatara o nga rahinga rereke mo tetahi wa i raro i te ohooho tonu me nga tikanga taapiri rereke, ka horoi ki te wai kia te korekore, me te centrifuged, I muri i te whakamaroketanga, whakamaroke korehau i te 60 °C;
5. Te hanga hiko o te kauwhata whakawhanui.
Ka tukuna te paura kawhata ki roto i te waikawa waikawa kaha hei hanga i te kauwhata whakawhanui, ka whakamarohia, ka horoi, ka whakamaroke. I te mea ko te waikawa kaha, te waikawa pungatara, te waikawa nitric ranei e whakamahia ana. Ko te kauwhata whakawhanui ka whiwhi i tenei tikanga he iti te whanariki.
