He aha nga ahuatanga o te kauwhata whakawhanui i muri i te whakamahana ki te kauwhata whakawhanui?

Ko nga ahuatanga roha opepa kauwhata whakawhanuihe rereke mai i etahi atu apiha roha. Ka whakamahana ki tetahi pāmahana, ka timata te kauwhata whakawhänui ki te whakawhänui na te pirau o nga puhui ka uru ki roto i te kurupae whakawhitiwhiti, e kiia nei ko te pāmahana roha tuatahi. Ka tino whakaroa ki te 1000 ℃ ka eke ki te rōrahi mōrahi. Ka taea e te rōrahi roha te neke atu i te 200 wa o te uara tuatahi. Ko te kauwhata whakawhanui e kiia ana ko te graphite whakawhanui, he kutukutu graphite ranei, ka huri mai i te ahua tawerewere taketake ki te ahua noke he iti te kiato, ka hanga he paparanga waiariki tino pai. Ko te kauwhata whakawhanui ehara i te mea he puna waro noa i roto i te punaha roha, engari he paparanga arai. Ka taea te whai huawhakamahana wera. I roto i te ahi, kei a ia nga ahuatanga o te tere tuku wera iti, te iti o te mate papatipu me te iti o te hau rewharewha.

He aha nga ahuatanga o te kauwhata whakawhanui i muri i te whakamahana ki te kauwhata whakawhanui?

Nga ahuatanga o te kauwhata whakawhanui

① He kaha te pehanga,ngawari, kirihou me te whakahinuhinu whaiaro;

② He kaha te atete ki te teitei, te iti o te pāmahana,waikurame te radiation;

③ He tino kaha nga ahuatanga ruru;

④ Tino kahate kawe;

He kaha ki te whakaheke i te koroheketanga me te aukati i nga ahuatanga.

⑥ Ka taea e ia te aukati i te rewa me te kuhu o nga momo konganuku;

⑦ Karekau he paitini, karekau he mate pukupuku, kaore hoki he kino ki te taiao.

He maha nga ahunga whanaketanga o te kauwhata whakawhanui e whai ake nei:

1. Kauwhata whakawhanui mo nga kaupapa motuhake

E ai ki nga whakamatautau ka whai mahi nga noke kauwhata ki te ngongo ngaru hiko. Ko te kauwhata whakawhanui me tutuki nga whakaritenga e whai ake nei: (1) iti te pāmahana roha tuatahi me te rōrahi roha nui; (2) Ko nga ahuatanga matū he pumau, ka rongoa mo te 5 tau, a ko te owehenga roha e kore e pirau; (3) Ko te mata o te kauwhata whakawhanui he koretake, kaore he waikura ki te pouaka kariri.

2. Kauwhata whakawhänuihia

Ko te matūriki iti te kauwhata whakawhänui te nuinga e pä ana ki te 300 mesh graphite whakawhänui me te rörahi roha o te 100ml / g. Ka whakamahia tenei hua mo te mura ahipaninga, he nui te hiahia.

3. Kauwhata roha ki teitei teitei pāmahana roha tuatahi

Ko te pāmahana roha tuatahi o te kauwhata whakawhanui me te pāmahana roha tuatahi teitei ko 290-300 ℃, me te rōrahi roha ko ≥ 230ml / g. Ko tenei ahua o te kauwhata whakawhanui ka whakamahia mo te mura ahi o nga kirihou miihini me te rapa.

4. Papa kauwhata whakarerekētia

Ka whakamahia te kauwhata whakawhanui hei mea mura ahi, ka uru ki te hototahi i waenga i te kauwhata me etahi atu waahanga. Na te nui o te kohuke o te mata kauwhata, ehara i te lipophilic, hydrophilic ranei. Na reira, me whakarereke te mata o te kauwhata ki te whakaoti i te raruraru o te hototahi i waenga i te kauwhata me etahi atu waahanga. Ko te whakaaro kia ma te mata kauwhata, ara, ki te uhi i te mata kauwhata ki te kiriata ma totoka, he raru uaua te whakaoti. Kei roto i te matū membrane, te matū mata ranei. Ka taea e te taiwhanga te mahi pera, a he uaua ki te mahi ahumahi. Tenei ahua o te kauwhata whakawhänui ma te nuinga whakamahia rite paninga mura.

5. He iti te pāmahana roha tuatahi me te iti o te pāmahana whakawhanui kauwhata

Ko tenei ahua o te kauwhata whakawhanui ka timata ki te whakawhānui i te 80-150 ℃, ka tae te rōrahi roha ki te 250ml / g i te 600 ℃. Ko nga uauatanga ki te whakarite kauwhata whakawhanui kia tutuki i tenei ahuatanga ko: (1) te kowhiri i te kaihoko whakawhiti tika; (2) Te whakahaere me te mohio ki nga tikanga whakamaroke; (3) Te whakatau i te makuku; (4) Te otinga o nga raruraru tiaki taiao.
