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 whakaahuru, 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 graphite kua whakawhānuihia e kiia ana ko te graphite kua whakawhānuihia, he kutukutu graphite ranei, ka huri mai i te ahua o te 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;

⑤He 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 graphite whakawhänui te nuinga ki te 300 mata whakawhänui kauwhata ki te rōrahi roha o 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 te 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. Kauwhata whakarerekē mata

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 te paninga mura retardant.

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.
