Kōrero mō ngā taputapu whakaputa me te ahunga whakamua hangarau o te paura korundum parauri
Hei mea whakakoi ahumahi nui, he mea nui te mahi a te korundum parauri i roto i te huri tika, te whakakanapa me ētahi atu mara. I te whakapai tonutanga o ngā whakaritenga a te umanga hanga hou mō te tukatuka tika, kei te auaha tonu te tukanga whakaputa me ngā taputapu o te paura korundum parauri.
1. Te tukanga whakaputa paura kōrundum parauri
Ko te nuinga o te raina whakaputa paura kōrunuma parauri ko te tukatuka rauemi mata, te kuru, te whakarōpū, te takai me ētahi atu tukanga. Ko ngā rauemi mata kounga teitei ka kuruhia tuatahitia e te mīhini kuru kauae, kātahi ka kuruhia ki te kuru waenga e te mīhini kuru kōne, e te mīhini kuru roera rānei. I te wāhanga kuru pai, ka whakamahia ngā mīhini kuru pānga poutū, ngā mira pōro rānei hei kuru i ngā rauemi ki te 300 mata. Ko te tukanga kuru pai rawa atu whakamutunga me whai taputapu motuhake pērā i ngā mira rere hau, ngā mira wiri rānei.
2. Te tātari hangarau taputapu whakaputa matua
1. Te auahatanga hangarau taputapu kuru
Ko ngā ngoikoretanga o ngā mira pōro tuku iho ko te nui o te kaha e pau ana, me te iti o te whai huatanga. Ko te mira whakaoho hou he hoahoa whakaoho ahurei, e whakapai ake ana i te whai huatanga o te huri mā te neke atu i te 30%. Ko te mea nui ake ko te hangarau kuru hau i puta ake i ngā tau tata nei e whakamahi ana i te hau tere-teitei hei mea kia tukinga, kia kuru hoki ngā matūriki tetahi ki tetahi, kia kore ai e poke te konganuku, ā, he tino pai mō te hanga paura moroiti me ngā whakaritenga parakore teitei. Ka taea e te pūnaha mira hau moenga wai i whakauruhia e tetahi umanga te whakahaere i te rahi o te matūriki hua i roto i te awhe D50=2-5μm, ā, he ōrite ake te tohatoha rahi matūriki.
2. Te whanaketanga pai o ngā taputapu whakatauranga
Kua piki ake te tere o te whakarōpū tāpine mai i te tīmatanga o te 3000rpm ki te neke atu i te 6000rpm, ā, kua tino pai ake te tika o te whakatauranga. Ko te pūnaha whakatauranga maha-rotor whakapae hou e whakamahi ana i te hoahoa raupapa o ngā wira whakatauranga maha, ā, e mahi tahi ana me te pūnaha whakahaere atamai hei whakatutuki i te tapahi rahi matūriki tika ake. Ko te hangarau whakatauranga āwhina ultrasonic i whakawhanakehia e ngā wae rangahau pūtaiao e whakamahi ana i ngā ngaru ultrasonic hei whakapai ake i te marara o ngā paura me te whakanui ake i te pai o te whakatauranga mā te 25%.
3. Pūnaha whakahaere aunoa
Ko ngā raina whakaputa hou e whakamahi ana i ngā pūnaha whakahaere PLC hei whakatutuki i te hononga taputapu me te whakatikatika aunoa i ngā tawhā. Ko ngā otinga matatau ake ka whakauru i te hangarau tirohanga mīhini hei aroturuki i te tohatoha rahi o te matūriki paura ipurangi me te whakatikatika i ngā tawhā tukanga i te wā tūturu mā roto i ngā pūnaha urupare.
I tēnei wā,paura moroiti kōrunuma parauriKei te whanake haere ngā taputapu whakaputa i te huarahi ki te whai huatanga, te tika me te mohio. E kore e taea e te auahatanga hangarau te whakapai ake i te kounga hua me te whai huatanga whakaputa anake, engari ka whakatairanga hoki i te whanaketanga pumau o te umanga katoa. I te heke mai, me te puta tonu mai o ngā rauemi hou me ngā tukanga hou, ka ārahi te hangarau whakaputa paura moroiti parauri i ngā putanga nui ake. Me aro nui ngā umanga ki ngā ia whanaketanga hangarau, me te whakapai tonu i ngā taputapu, te whakapai ake i ngā tukanga, me te pupuri i ngā painga hangarau i roto i te whakataetae mākete.
