Tikanga whakakanapa i te pokepokea ai kirihou

Te whakakanapa mīhini

Ko te whakakanapa ā-ringa he tikanga whakakanapa e whakawhirinaki ana ki te tapahi me te whakarerekētanga kirihou o te mata o te rauemi hei tango i ngā wāhanga pūkohu kua whakakanapahia kia whiwhi ai i te mata maeneene. Ko te tikanga, ka whakamahia ngā rākau kōhatu hinu, ngā wira huruhuru hipi, te pepa kirikiri, me ētahi atu, ā, ko ngā mahi ā-ringa te tikanga matua. Ka taea te whakamahi i ngā wāhanga motuhake pēnei i te mata o te tinana hurihuri. Mā te whakamahi i ngā taputapu āwhina pēnei i ngā tēpu hurihuri, ka taea te whakamahi i te whakakanapa tino tika mō te hunga he nui ngā whakaritenga kounga mata. Ko te whakakanapa tino tika ko te whakamahi i ngā taputapu whakakoi motuhake, ka pēhia kia piri ki te mata tukatuka o te mea mahi i roto i te wai whakakanapa kei roto ngā whakakoi hei huri tere. Mā te whakamahi i tēnei hangarau, ka taea te whakatutuki i te taratara o te mata o Ra0.008μm, koinei te mea teitei rawa atu i roto i ngā momo tikanga whakakanapa. He maha ngā wā ka whakamahia tēnei tikanga e ngā pokepokea ai te arotahi whatu.

Te whakakanapa matū

Ko te whakakanapa matū he mea kia memeha te mata o te rauemi i roto i te rauemi matū, kia pai ake ai te memeha i te wāhanga piko, kia maeneene ai te mata. Ko te painga matua o tēnei tikanga, kāore e hiahiatia he taputapu uaua, ka taea te whakakanapa i ngā mahi he āhua uaua, ā, ka taea te whakakanapa i ngā mahi maha i te wā kotahi, me te tino whai hua. Ko te raru matua o te whakakanapa matū ko te whakarite i te wai whakakanapa. Ko te taratara o te mata e puta mai ana i te whakakanapa matū he 10 μm te nuinga.

Te whakakanapa hikohiko

Ko te kaupapa matua o te whakakanapa hikohiko he rite tonu ki te whakakanapa matū, arā, mā te whakarewa i ngā mea iti i runga i te mata o te rauemi kia maeneene ai te mata. Ki te whakatauritea ki te whakakanapa matū, ka taea te whakakore i te pānga o te tauhohenga katote, ā, he pai ake te pānga. E rua ngā taahiraa o te tukanga whakakanapa hikohiko: (1) Te whakataurite nui Ka horapa ngā hua rewa ki roto i te irahiko, ā, ka heke te taratara āhuahanga o te mata o te rauemi, Ra>1μm. ⑵ Te whakataurite iti-mārama: Te whakapolarisasi o te anode, ka pai ake te kanapa o te mata, Ra<1μm.

Te whakakanapa ultrasonic

Whakanohoia te mea mahi ki roto i te whakatārewatanga whakakoi, ka whakakotahi ki roto i te mara ultrasonic, me te whakawhirinaki ki te pānga wiri o te ultrasonic, kia hurihia ai te whakakoi, kia orohia ai ki runga i te mata o te mea mahi. He iti te kaha makaro o te miihini ultrasonic, ā, e kore e puta he rerekētanga o te mea mahi, engari he uaua ki te hanga me te tāuta i ngā taputapu. Ka taea te whakakotahi i te tukatuka ultrasonic me ngā tikanga matū, hiko rānei. I runga i te waikura otinga me te hikohiko, ka whakamahia te wiri ultrasonic hei whakaoho i te otinga, kia wehea ai ngā hua rewa i runga i te mata o te mea mahi, kia ōrite ai te waikura, te electrolyte rānei e tata ana ki te mata; ka taea hoki e te pānga cavitation o te ultrasonic i roto i te wai te aukati i te tukanga waikura me te whakahaere i te whakamārama o te mata.

Te whakakanapa wai

Ko te whakakanapa wai e whakawhirinaki ana ki te wai rere tere me ngā matūriki whakakoi e haria ana e ia hei horoi i te mata o te mea mahi kia tutuki ai te kaupapa o te whakakanapa. Ko ngā tikanga e whakamahia whānuitia ana ko: te tukatuka jet whakakoi, te tukatuka jet wai, te huri waiora me ērā atu. Ko te huri waiora ka peia e te pēhanga waiora kia rere ai te wai e haria ana ngā matūriki whakakoi puta noa i te mata o te mea mahi i te tere teitei. Ko te nuinga o te waiora he mea hanga mai i ngā matū motuhake (ngā matū rite ki te polymer) he pai te rere i raro i te pēhanga iti, ā, kua konatunatua ki ngā mea whakakoi. Ka taea te hanga i ngā mea whakakoi mai i te paura silicon carbide.

Te huri me te whakakoi aukume

Ko te whakakanapa aukume ko te whakamahi i ngā mea whakakanapa aukume hei hanga paraihe whakakanapa i raro i te mahi a te papa aukume hei huri i te mea mahi. He pai te tukatuka o tēnei tikanga, he kounga pai, he ngāwari te whakahaere i ngā āhuatanga tukatuka me ngā āhuatanga mahi pai. Mā te whakamahi i ngā mea whakakanapa e tika ana, ka taea e te taratara o te mata te eke ki te Ra0.1μm. 2 Te whakakanapa miihini i runga i tēnei tikanga He tino rerekē te whakakanapa e whakahuatia ana i roto i te tukatuka i ngā pokepokea kirihou i te whakakanapa mata e hiahiatia ana i roto i ētahi atu ahumahi. Ko te tikanga, me kī te whakakanapa o te pokepokea he tukatuka whakaata. Ehara i te mea he nui ngā whakaritenga mō te whakakanapa i a ia anō, engari he paerewa teitei hoki mō te papatahi o te mata, te maeneene me te tika o te āhua. Ko te whakakanapa mata i te nuinga o te wā e hiahiatia ana he mata kanapa anake. E whā ngā taumata o te tukatuka mata whakaata e wehea ana: AO=Ra0.008μm, A1=Ra0.016μm, A3=Ra0.032μm, A4=Ra0.063μm. He uaua ki te whakahaere tika i te tika o te āhua o ngā wāhanga nā ngā tikanga pēnei i te whakakanapa hiko me te whakakanapa wai. Heoi, kāore te kounga o te mata o te oro matū, te oro ultrasonic, te oro aukume me ētahi atu tikanga e tutuki ana i ngā whakaritenga, nō reira ko te tukatuka whakaata o ngā pokepokea tika he oro miihini tonu.
