Ki taku whakaaro he tokomaha te hunga e mōhio ana ki te mea he mea whakarewa? He matū aukume te mea whakarewa i hangaia i roto i te taiao. He maha ngā momo o tēnei matū. Ka taea te whakamahi i ētahi mea whakarewa hei hanga taonga whare, ā, ka taea te whakamahi i ētahi mea whakarewa hei hanga whakapaipai. Me whakakanapa te nuinga o ngā mea whakarewa i te wā e tukatukahia ana. Mō te whakakanapa whakarewa, ka whakamahia ngā taputapu whakakanapa ngaio. E mōhio ana koe ki ngā whakamahinga o ngā taputapu whakakanapa me te huri i ngā mea whakarewa? Inaianei ka hoatu e Z-LION he whakataki taipitopito ki a koe.
Te hangarau huri me te whakakanapa whakarewa
1. Te whakakanapa ā-mīhini
Ko te whakakanapa ā-ringa he tikanga whakakanapa e whiwhi ai i tētahi mata maeneene mā te tapahi me te whakarerekētanga kirihou o te mata o te rauemi hei tango i te wāhanga pūkohu kua whakakanapahia. I te nuinga o te wā,Ngā Rīpene Emery Taimana, ngā wira huruhuru hipi, te pepa kirikiri,ngā papa whakakanapa taimana, te wira kirikiri taimana me ētahi atu. Mā te whakamahi i ngā taputapu āwhina pēnei i ngā tēpu hurihuri, ka taea te whakamahi i ngā tikanga huri me te whakakanapa tino pai mō te hunga he nui ngā whakaritenga kounga mata. Ko te huri me te whakakanapa tino tika he taputapu whakakanapa motuhake, ka pēhia ki te mata o te mea mahi kia mīhinihia ki roto i te wai huri me te whakakanapa kei roto he whakakanapa, ā, ka huri i te tere teitei. 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 ngā karaihe whatu.
2. Te whakakanapa matū
Ko te whakakanapa matū he tuku i ngā wāhanga e puea ake ana i roto i te rauemi kia memeha haere i runga ake i ngā wāhanga piko i roto i te rauemi matū, kia maeneene ai te mata. Ko te painga matua o tēnei tikanga, kāore e hiahiatia he taputapu uaua, ka taea te whakakanapa i ngā wāhanga mahi he āhua uaua, ā, ka taea te whakakanapa i ngā wāhanga 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.
3. 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 awe 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 hikohiko, ā, ka heke te taratara āhuahanga o te mata o te rauemi, ā, ka heke te Ra>1μm. (2) Te whakataurite iti o te māramatanga Ka pōraritanga anodic, ka pai ake te kanapa o te mata, Ra<1μm.
4. Te whakakanapa i te ultrasonic
Ka whakanohoia te mea mahi ki roto i te whakatārewatanga whakakoi, ka whakanohoia ki roto i te mara ultrasonic, ā, ka hurihia te whakakoi, ka orohia ki runga i te mata o te mea mahi mā te wiri o te ngaru ultrasonic. He iti te kaha nui o te tukatuka ultrasonic, ā, e kore e puta he rerekētanga o te mea mahi, engari he uaua ki te hanga me te tāuta i te taputapu. Ka taea te whakakotahi i te miihini 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 cavitation o ngā ngaru ultrasonic i roto i te wai te aukati i te tukanga waikura, e whai hua ana ki te whakamārama i te mata.
5. Te whakakanapa wai
Ko te whakakanapa wai he horoi i te mata o te mea mahi kia rite ki te wai e rere tere ana me ngā matūriki whakakoi e mau ana i roto hei whakatutuki i te kaupapa o te whakakanapa. Ko ngā tikanga e whakamahia whānuitia ana ko: te miihini pupuhi whakakoi, te miihini pupuhi wai, te huri waiora, me ētahi atu. Ko te huri waiora ka peia e te pēhanga waiora, kia rere tauutuutu ai te wai e mau ana i 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 he pai te rere i raro i te pēhanga iti, ā, ka konatunatua ki ngā mea whakakoi, ā, ko ngā mea whakakoi ka taea te hanga hei paura silicon carbide.
6. Te huri me te whakakanapa aukume
Ko te huri me te whakakanapa aukume he whakamahi i ngā mea whakakoi aukume hei hanga paraihe whakakoi i raro i te mahi a te papa aukume hei huri i ngā wahi mahi. He pai te tukatuka o tēnei tikanga, he kounga pai, he ngāwari te whakahaere i ngā āhuatanga tukatuka, ā, he pai hoki ngā āhuatanga mahi. Mā ngā mea whakakoi e tika ana, ka taea e te taratara o te mata te eke ki te Ra0.1μm.
Ka pai ake te pānga o te nuinga o ngā whakakanapa whakarewa i muri i te whakakanapa. Ka taea e te whakakanapa whakarewa te whakaeneene ake, te whakanikoniko ake hoki i te mata whakarewa. Ko te nuinga o ngā taonga whare me ngā mea whakapaipai whakarewa ka tukatukahia, ka whakakanapahia i mua i te hokonga atu ki te mākete. He maha ngā taputapu me ngā taputapu e whakamahia ana mō te whakakanapa me te huri i ngā whakarewa, ā, he rerekē anō hoki ngā mātāpono mahi. Ina whiriwhiria e tātou ngā mīhini me ngā taputapu rerekē, me tīmata tātou mai i tōna mātāpono.
