He arotake i ngā rangahau whakarerekētanga mata o ngā muka basalt
Hei rauemi muka kore-waro mahi-teitei, he tino pai ngā āhuatanga miihini o te muka basalt, Matū Nā te ātete me te pumau o te pāmahana teitei kua puta ai ngā tono maha i roto i te hangarau ā-iwi, ngā rauemi hiato, me te tiaki taiao. Heoi, he maeneene ngā mata o ngā muka paparata, ā, kāore he rōpū mahi hohe, ka hua ake he ngoikore ngā āhuatanga hononga ā-kanohi ki ngā rauemi matihiko. Nō reira, ka taea e te whakarerekētanga mata o ngā muka paparata te whakapai ake i ō rātou āhuatanga hononga ā-kanohi me te whakarei ake i tā rātou tono i roto i ngā hiato me ngā mara tiaki taiao. Koinei te ahunga whakamua rangahau o ētahi tikanga whakarerekētanga nui.
- Te whakarerekētanga o te mata o te kaihoko hononga silane
Ko te kaihopu hononga silane he kaihopu maimoatanga mata e whakamahia whānuitia ana e whakapai ake ana i ngā āhuatanga hononga ā-mata i waenga i ngā muka me ngā rauemi matihiko mā te hononga matū.
Whakarerekētanga KH-550
E whakaatu ana te rangahau mā te rongoā i ngā muka basalt ki te otinga silane coupling agent KH-550 ka hanga hononga matū pumau ki te mata o te muka, ā, ka whakapai ake i te hononga ā-kanohi i waenga i te muka me te uku. Ko te kukū whaitake o te KH-550 he 1.0%, ā, ko te wā rongoā he 30 meneti. I muri i te whakarerekētanga, i whakapai ake te piri i waenga i te muka basalt me te uku mā te 1 taumata. I piki ake te tere mimiti hinu mā te 65.5%, ā, i tino whakarei ake i te piri ki te uku.
KH-570 Whakarerekētanga
Ka whakarerekētia e te KH-570 ngā muka o te papara hei whakararo i tōna mata, hei whakanui ake hoki i ngā pūwāhi hohe i runga i te mata o te muka. I roto i te rauemi hiato, mā te pikinga ake o te roa o te muka kua whakarerekētia me te nui o te tāpiri, ka tino pai ake ngā āhuatanga ā-pūkaha o te rauemi hiato.
- Te whakarerekētanga o te matū horoi
Te whakarerekētanga CTAC
Mā te paninga ā-tinana o ngā muka basalt ki te cationic surfactant cetyltrimethylammonium chloride (CTAC) ka pai ake te hydrophilicity me te dispersibility o ngā muka ki te wai. He pānga nui tēnei tikanga whakarerekētanga ki te piri o te kiriata moroiti: ka tino piki ake te kaha piri o te moroiti. Mā te whakanui ake i te nui o te piri o te moroiti ka māmā ake te tono i roto i te maimoatanga wai para.
- Te whakarerekētanga o te whakatakotoranga wai rino waro
Mā te whakarerekētanga o ngā muka o te papara mā te whakatakoto i te rino waro ki roto i te wai ka taea te whakapai ake i te kaha piri-koiora o te mata o te muka, me te whakarei ake i tōna whakamahinga i roto i te maimoatanga waipara. Mā tēnei tikanga whakarerekētanga ka taea te hanga i tētahi paninga waikura rino pumau ki runga i te mata o te muka hei whakapai ake i tōna mimiti me te pakaru o ngā poke.
- Te whakarerekētanga paninga mā te nano-silica
Ka horapa ōrite ngā matūriki nanosilica i roto i te mea e uru ana, e horapa ana rānei, ā, ka taea te whakarerekē i te paninga muka basalt: i waenga i te muka basalt me te kapia epoxy, ka whai wāhi ngā matūriki nanosilica ki te piriti, ka whakapai ake i te hototahitanga o te atanga i waenga i ngā mea e rua. I muri i te whakarerekētanga, ka piki ake te taratara o te mata o te muka basalt, ka piki ake te horahanga mata motuhake, ā, ka piki ake ngā rōpū mahi kei roto te hāora. I whakaatuhia e te rangahau mā te whakamahi i te kaikawe muka basalt kua whakarerekētia ki te nanosilica: ka piki ake te nui o te kiriata moroiti mō ia karamu o te muka kua mauhia mā te 21.39%. I tino pai ake te pai o te tango parahanga.
Whakatau me te Tirohanga
I tino whakapaitia te ngohe o te mata, ngā āhuatanga hononga ā-kanohi me te mahi a ngā muka basalt e ngā tikanga whakarerekētanga mata rerekē. I roto i ēnei:
- He pai ake te whakarerekētanga o te kaihoko hononga silane hei whakapai ake i te piri o ngā muka basalt ki ngā rauemi matrix (hei tauira, te sima, te uku, te kapia epoxy, me ētahi atu).
- He pai ake te whakarerekētanga surfactant me te whakarerekētanga whakatakotoranga rino waro mō te mara tiaki taiao, inā koa mō te tono kawe moroiti i roto i te maimoatanga paru.
- He whānuitia ngā huarahi e taea ai te whakarerekē i te paninga nano-silica, me ngā painga o te whakapai ake i ngā āhuatanga ā-pūkaha me te mahi. Ngā Rauemi Whakakotahi me te tiaki taiao.
Ka taea e ngā rangahau ā muri ake nei te whakapai ake i ngā tawhā o te tukanga whakarerekētanga me te tūhura i te pānga mahi tahi o ngā tikanga whakarerekētanga rerekē hei whakatutuki i ngā hiahia o ngā tono rerekē.
