Ko te kauwhata whakawhanui he matū noke kua rite ki te kutukutu karekau me te pore i mahia mai i nga tawerewere kauwhata na roto i nga tukanga o te whakawhitiwhiti, te horoi wai, te whakamaroke me te roha teitei o te pāmahana. Ka taea e te graphite te whakawhānui ake i te 150 ~ 300 nga wa i roto i te rōrahi i te wa e pa ana ki te teitei o te wera, ka huri mai i te tawerewere ki te kutukutu, kia matara te hanganga, porous me te kopikopiko, ka nui ake te mata o te mata, ka pai ake te kaha o te mata, me te ka whakanuia te kaha whakauru o te kauwhata tawerewere. whakakotahi, e whakanui ana i te ngawari, te kaha me te kirihou. Ma te ētita e whai ake nei e whakamarama ki a koe etahi huarahi whanaketanga matua o te kauwhata whakawhanui:
1. graphite Granular roha: Small granular roha graphite te nuinga e pā ana ki te 300 mata whakawhänui kauwhata, me tona rōrahi roha ko 100ml/g. Ko te nuinga o tenei hua ka whakamahia mo nga paninga mura ahi, a he nui rawa te tono.
2. graphite roha ki tiketike pāmahana roha tuatahi: te pāmahana roha tuatahi ko 290-300 ° C, me te rōrahi roha ko ≥ 230 ml/g. Ko tenei momo kauwhata whakawhanui e whakamahia ana mo te aukati mura o nga kirihou miihini me te rapa.
3. Te iti o te pāmahana roha tuatahi me te iti o te pāmahana whakawhänui kauwhata: ko te pāmahana i timata ai tenei momo kauwhata whakawhänui ki te whakawhänui ko te 80-150°C, ka tae te riki roha ki te 250ml/g i te 600°C.
Ka taea e nga kaihanga kauwhata whakawhanui te tukatuka i te kauwhata whakawhanui hei kauwhata ngawari hei whakamahi hei taonga hiri. Ki te whakatauritea ki nga taonga hiri o mua, he whanui ake nga momo mahana e taea ana te whakamahi, mai i te -200°C ki te 450°C i roto i te rangi, he iti te whakareatanga whakareatanga werawera. Kua whakamahia nuitia i roto i te petrochemical, miihini, metallurgy, hiko ngota me etahi atu ahumahi.
