Ko te kauwhata he putunga o te waro, he karaihe whakawhiti i waenga i nga tioata ngota, tioata maitai me nga tioata ngota. Tino mangu te pango, kakano ngohengohe, ahua hinuhinu. Te wera kua piki i te hau, i te oxygen ranei e tahu ana ka whakaputa i te hauhā. waikawa koiora. I whakamahia hei kaihoko antiwear me nga mea whakahinuhinu, hei hanga i te ipu, i te hiko, i te puhiko maroke, i te pene pene. Ko te whanui o te kitenga o te kauwhata: kauwhata taiao, kauwhata tioata kikorangi, kauwhata tawewe, graphite cryptocrystalline, kauwhata paura, pepa kauwhata, kauwhata whanui, emulsion graphite, graphite whakaroha, graphite paru me te graphite conductive paura, etc.
1. awangawanga teitei: ko te ira rewa o te kauwhata he 3850 ± 50 ℃, ahakoa i muri i te wera nui o te wera o te wera, he iti rawa te ngaronga, he tino iti te whakarea whakarea waiariki. Ka piki haere te kaha o te kauwhata me te piki haere o te mahana. . I te 2000 ℃, te kaha o te kauwhata e rua.
2. conductive, kawe waiariki: te kawe o te kauwhata he kotahi rau wa teitei ake i te whanui kore-konganuku. Ko te kawe waiariki o te maitai, rino, mata me etahi atu mea whakarewa. Ka heke te kawe waiariki me te pikinga o te mahana, ara rawa atu teitei te pāmahana, graphite ki te mātao;
3. whakahinuhinu: ko te whakahinuhinu o te kauwhata i runga i te rahi o te wherikotanga o te kauwhata, o te putake, o te whakarea waku he iti ake, he pai ake te mahi whakahinuhinu;
4. pumau matū: graphite i te pāmahana rūma he pūmautanga matū pai, ātete waikawa, ātete alkali me ātete waikura aukume aukati;
5. kirihou: he pai te pakari o te graphite, ka taea te kuru ki tetahi pepa tino angiangi;
6. awangawanga awangawanga o te waiariki: te kauwhata i te mahana o te ruuma ka taea te tu i nga rereketanga nui o te mahana kaore he kino, te rereketanga o te pāmahana, te rahinga o te kauwhata huri iti, kaore e pakaru.
1. te taatai tito: waro tuturu, makuku, poke, aha;
2. Te whakamatautau i nga mahi a-tinana: te pakeke, te pungarehu, te pokarekare, te angitu, te rahinga o te korakora, te whakahekeheke, te tino taumaha, te waahanga o te mata, te rewa, te aha.
3. whakamatauhia nga miihini miihini: te kaha kaha, te parauri, te piko o te whakamatautau, te whakamatautau taatai;
4. te whakamatautau mahi matū: te aukati wai, te mauroa, te waikawa me te aukati i te aukati, te aukati i te waikura, te awangawanga o te rangi, te aukati i te wera, me era atu
5. Ko etahi atu mea whakamatautau: te kawe hiko, te kawe waiariki, whakahinuhinu, te pumau o te matū, te aukati i te ru o te waiariki
