Te Whakakore Hinu i te Pepa Parahi Hurihia: Te Tukanga Matua me te Whakapūmau Matua mō te Mahi Paninga me te Whakakī Wera

Pepa parahi hurihuriHe rauemi matua te rauemi nei i roto i te umanga ara iahiko hiko, ā, ko tōna mata me tōna ma o roto e whakatau tika ana i te pono o ngā tukanga o muri mai pērā i te paninga me te whakamātao wera. Ka tātarihia e tēnei tuhinga te tikanga e arotau ai te maimoatanga tango hinu i te mahi o te pepa parahi hurihuri mai i ngā tirohanga whakaputa me te tono. Mā te whakamahi i ngā raraunga tūturu, ka whakaatuhia tōna urutau ki ngā horopaki tukatuka pāmahana teitei. Kua whakawhanakehia e CIVEN METAL tētahi tukanga tango hinu hohonu motuhake e pakaru ana i ngā arai ahumahi, e whakarato ana i ngā otinga pepa parahi pono mō te hanga hiko teitei.

1. Te Kaupapa Matua o te Tukanga Whakakore Hinu: Te Tango Takirua i te Mata me te Hinu o Roto

1.1 Ngā Take Hinu Toenga i roto i te Tukanga Hurihuri

I te wā e hangaia ana te pepa parahi hurihuri, ka maha ngā takahanga hurihuri o ngā poro parahi hei hanga i te rauemi pepa parahi. Hei whakaiti i te wera o te waku me te kakahu o te poro, ka whakamahia ngā hinu whakahinuhinu (pēnei i ngā hinu kohuke me ngā ester hangai) i waenganui i ngā poro me tepepa parahimata. Heoi, e rua ngā ara matua o tēnei tukanga hei pupuri i te hinu:

• Te mimiti o te mataI raro i te pēhanga hurihuri, ka piri te kiriata hinu tauine-maikoron (0.1-0.5μm te matotoru) ki te mata o te pepa parahi.
• Te werohanga o rotoI te wā e hurihuri ana te āhua, ka puta he hapa moroiti i roto i te whatunga parahi (pēnei i te nekehanga me te āputa), ka taea ai e ngā ngota hinu (ngā mekameka hauwaiwai C12-C18) te uru ki roto i te pepa konutea mā te mahi kapia, ka tae ki te hohonutanga o te 1-3μm.

1.2 Ngā Here o ngā Tikanga Horoi Tuku Iho

Ko ngā tikanga horoi mata tuku iho (hei tauira, te horoi kawakore, te muru waipiro) ka tangohia noa ngā kiriata hinu mata, ā, ka eke ki te tere tango tata ki te70-85%, engari kāore e whai hua ki te hinu e mimitihia ana e roto. E whakaatu ana ngā raraunga whakamātautau, ki te kore e tangohia te hinu hohonu, ka puta anō te hinu o roto ki te mata i muri i te30 meneti i te 150°C, me te tere whakatakotoranga anō o0.8-1.2g/m², e hua ai te "paru tuarua."

1.3 Ngā Huarahi Hou o te Hangarau mō te Whakakore Hinu Hōhonu

He kaimahi a CIVEN METAL"tango matū + whakahohenga ultrasonic"tukanga whakahiato:

1. Te tango matūKa wawahia e te ākena chelating ritenga (pH 9.5-10.5) ngā ngota hinu mekameka roa, ka hanga he matatini wairewa-wai.
2. Āwhina ultrasonicMā te ultrasound auau-teitei 40kHz ka puta he pānga cavitation, ka pakaru te kaha here i waenga i te hinu o roto me te whatunga parahi, ka whakarei ake i te pai o te whakarewanga o te hinu.
3. Whakamaroke korehauMā te maroke tere i te pēhanga kino -0.08MPa ka ārai i te waikura.

Ka whakaitihia e tēnei tukanga ngā toenga hinu ki≤5mg/m²(e tutuki ana i ngā paerewa IPC-4562 o ≤15mg/m²), e tutuki ana>99% te pai o te tangomō te hinu e mimitihia ana e roto.

2. Te Pānga Tika o te Maimoatanga Whakakore Hinu ki ngā Tukanga Paninga me te Whakakī Wera

2.1 Te Whakapai Ake i te Piripiri i roto i ngā Mahi Paninga

Me hanga e ngā rauemi paninga (pēnei i ngā piripiri PI me ngā ātete whakaahua) he hononga taumata-ngota kipepa parahiKo ngā toenga hinu ka hua ake i ēnei raruraru:

• Te whakaiti i te kaha ā-mata: Ka whakanui ake te ātete wai o te hinu i te koki whakapā o ngā otinga paninga mai i15° ki te 45°, e aukati ana i te makuku.
• Te here matū kua āraihiaKa ārai te paparanga hinu i ngā rōpū hydroxyl (-OH) i runga i te mata parahi, ka ārai i ngā tauhohenga ki ngā rōpū hohe kapia.

Whakataurite Mahi o te Pepa Parahi Kua Whakakorehia te Hinu me te Pepa Parahi Noa:

2.2 Te Whakarei Ake i te Pono o te Whakakikoruatanga Wera

I te wā e pania ana ki te pāmahana teitei (180-220°C), ka hua ake ngā hapa maha nā te toenga o te hinu i roto i te pepa parahi noa:

• Te hanganga o te mirumiru: Ka hangaia e te hinu mimiti10-50μm ngā mirumiru(kiato >50/cm²).
• Te wehewehe i waenga i ngā paparangaKa whakaitihia e te hinu ngā kaha o van der Waals i waenga i te kapia epoxy me te pepa parahi, ka whakaitihia te kaha o te kiri mā te30-40%.
• Ngaronga hiko-kore: Ka puta ngā rerekētanga o te pūmau dielectric i te hinu kore utu (rerekētanga Dk >0.2).

I muri1000 hāora o te pakeketanga 85°C/85% RH, CIVEN METAPepa Parahingā whakaaturanga:

• Te matotoru o te mirumiru: <5/cm² (te toharite ahumahi >30/cm²).
• Kaha kiri: Pupuri1.6N/cm(uara tīmatanga1.8N/cm, 11% anake te tere o te pirau.
• Te pumau o te hikohiko: Rerekētanga Dk ≤0.05, huiNgā whakaritenga auau ngaru mirimita 5G.

3. Te Tūnga o te Ahumahi me te Tūnga Paerewa a CIVEN METAL

3.1 Ngā Wero o te Ahumahi: Te Whakangāwari i te Tukanga e Arotauhia ana e te Utu

Neke atu i te90% o ngā kaihanga pepa parahi hurihuriwhakangawari i te tukatuka hei whakaiti i ngā utu, mā te whai i tētahi tukanga mahi taketake:

Hurihuri → Horoi Wai (wairewa Na₂CO₃) → Whakamaroke → Whakataka

Ka tangohia noa e tēnei tikanga te hinu o te mata, me ngā piki me ngā heke o te ātete o te mata i muri i te horoinga±15%(Kei roto i te tukanga a CIVEN METAL±3%).

3.2 Te Pūnaha Whakahaere Kounga "Kore-Hapa" a CIVEN METAL

• Aroturuki ipurangiTe tātaritanga hihi-X (XRF) mō te kimi wā-tūturu i ngā huānga toenga o te mata (S, Cl, me ētahi atu).
• Ngā whakamātautau koroheketanga tereTe whakatauira i te tino200°C/24 hāorangā āhuatanga hei whakarite kia kore rawa e puta anō te hinu.
• Te whai i te tukanga katoaKei roto i ia rōra he waehere QR e hono ana ki32 ngā tawhā tukanga matua(hei tauira, te pāmahana tango hinu, te mana ultrasonic).

4. Whakamutunga: Te Whakakorenga Hinu—Te Pūtake o te Hanganga Hikohiko Tino Pai

Ehara i te mea he whakapai ake i te tukanga te tango hinu hohonu i te pepa parahi kua hurihia, engari he urutau whakamua ki ngā tono ā muri ake nei. Ka whakarei ake te hangarau hou a CIVEN METAL i te ma o te pepa parahi ki te taumata atomika, e whakarato anate whakapumautanga taumata-rawamōngā hononga kiato-teitei (HDI), ngā ara iahiko ngāwari o ngā motuka, me ētahi atu mara whai hua.

I roto i teTe wā o te 5G me te AIoT, ko ngā kamupene anake e whakahaere ana i tengā hangarau horoi matuaka taea te akiaki i ngā auahatanga ā-muri i roto i te umanga pepa parahi hiko.
