Chithandizo chamankhwala chofuula cha mkuwa: Njira yolumikizira ndi chitsimikizo cha kiyi

Zopindika zamkuntho zamkunthondi zinthu zokhudzana ndi magetsi mu zamagetsi zamagetsi, ndipo ukhondo wamkati ndi ukhondo umazindikira kudalirika kwa njira zoyambira monga kuyanjana. Nkhaniyi ikuwunika makina omwe maginiki amathandizira kuwongolera magwiridwe antchito a mkuwa kuchokera mbali zonse ziwiri kuchokera mbali zonse ziwiri kuchokera mbali zonse ziwiri. Pogwiritsa ntchito deta yeniyeni, imawonetsa kusintha kwake pamakina okwera kutentha kwambiri. Chitsulo cha CAven chakhala ndi njira yofananira yofunikira kwambiri yomwe imaphwanya mabotolo a makampani, ndikupatsa chithandizo chodalirika kwambiri kwa chinsalu cham'mkuwa chopanga pamagetsi otha.

1. Pachiyambi cha njirayi: Kuchotsa kwawiri ndi mafuta amkati

1.1 Zotsalira Zotsalira Pazomwe Zimayendetsa

Pakupanga zojambulazo zamkuwa zopsereza zonunkhira za mkuwa, mitengo yamkuwa yomwe imadutsa masitepe angapo kuti apange zoti zoti zibowo. Kuchepetsa kutentha kwamikangano ndi kuvala zovala, mafuta (monga mafuta a mchere ndi magawo a michere) amagwiritsidwa ntchito pakati pa ma roll ndiZojambula ZakukuluPamwamba. Komabe, njirayi imatsogolera ku mafuta posungira mbali ziwiri zoyambira:

• Pamtunda adsorption: Mukapanikizika kwambiri, filimu ya Micron-Scale-Scale.5μm wandiweyani) amatsatira zopika zamkuwa zamkuwa.
• Kulowa mkati: Pa nthawi yosinthitsa, yomwe ili pachiwopsezo cha mkuwa (monga momwe zimasinthira), kulola mamolekyulu a mafuta (C12-C18 hykrocar

1.2 Zofooka za njira zotsukira zachikhalidwe

Njira zoyeretsa zapadera (mwachitsanzo, kusamba kwa alkaline, kumwa mowa) kuchotsa mafilimu opangira mafuta okha, kukwaniritsa chochotsa pafupifupi70-85%, koma sizigwira ntchito motsutsana ndi mafuta. Zambiri zoyesera zikuwonetsa kuti popanda kuwunika, kuwonekera kwa mankhwalawa pambuyo pakeMphindi 30 ku 150 ° C, ndi kuchuluka kwa0.8-1.2g / m², kuwonongeka kwa "kwachiwiri."

1.3 Kusintha Kwaukadaulo

Centn chitsulo chimagwiritsa ntchito a"Mankhwala Ochotsa + akupanga"Njira Yophatikiza:

1. Kuchotsa mankhwala: Wothandizira Cherating (PH 9.5-10.5) amawola mamolekyutala otalika kwambiri, ndikupanga ma slurection osungunuka madzi.
2. Kuthandiza Kwa Akupanga: 40khz kutalika-pafupipafupi ultrasound imatulutsa zovuta, kuphwanya mphamvu yolumikizana pakati pa mafuta amkati ndi mafuta amkuwa, omwe amathandizira kumveketsa bwino kwambiri.
3. Kuwuma: Kuthamanga kwa madzi mwachangu ku -0.08MPA zoyipa kumalepheretsa makutidwetion.

Izi zimachepetsa mafuta otsala≤5mg / m²(Kusonkhana IPC-45622 Miyezo ya ≤15mg /m he), kukwaniritsa> 99% kuchotsa ntchitochifukwa chodzaza mafuta.

2. Mavuto a mankhwala okhudzana ndi ma biiti ndi mawongoledwe amafuta

2.1 Kupititsa patsogolo Ntchito Zogwirizanitsa

Zipangizo zokutira (monga pissites monga zithunzi ndipo zikuwonetsa kuti ndi zomangira zam'madziZojambula Zakukulu. Mafuta otsalira amabweretsa zotsatirazi:

• Kuchepetsedwa kuchepetsedwa: Hydrophobicity wa Grose amawonjezera mbali yolumikizirana yolumikizira15 ° mpaka 45 °, kuphwanya kunyowetsa.
• Choletsa mgwirizano wamankhwala: Mafuta a mafuta amasenda hydroxyl (--Oh) magulu amkuwa, kupewa zomwe zimachitika ndi maampani ogwirira ntchito.

Kufanizira kwa magwiridwe antchito a Deggent vs. zojambulazo zamkuwa pafupipafupi:

2.2 onjezerani kudalirika mu marrmal

Pa nthawi yayitali kwambiri (180-220 ° C), mafakiti otsalira muzomwezi mu Copper pafupipafupi zimabweretsa zolephera zingapo:

• Mapangidwe a bubble: Mafuta opatsirana ophatikizika10-50.50μm Bubbles(Tsamba> 50 / CME).
• Kulekana kwa Interllayer: Mafuta amachepetsa a Van der ander pakati pa epoxy utoto ndi zojambula zamkuwa, kuchepa kwa mphamvu ya30-40%.
• Kutayika kwa Dielert: Mafuta aulere amayambitsa kusinthasintha kwa dielectric nthawi zonse (DK Valiation> 0,2).

PatsogoloMaola 1000 a 85 ° C / 85% rh ukalamba, Zitsulo za centnZojambula ZakukuluZiwonetsero:

• Kuchulukitsa: <5 / cm² (makampani apakati> 30 / CME).
• Peel mphamvu: Amasunga1.6n / cm(mtengo woyamba1.8n / cm, kuwonongeka kokha 11%).
• Kukhazikika kwa sekondale: DK Valiation ≤0.05, kukumana5G millimeter-soll pafupipafupi.

3. Udindo wa mafakitale ndi mawonekedwe a chitsulo cha zitsulo

3.1 Zovuta zamakampani

Pamwamba90% ya opanga zamkuwaSakanikizira kukonza kuti muchepetse mtengo, kutsatira ntchito yoyambira:

Kugudubuza → Kusamba kwamadzi (Na₂co₃ Solution) → Kuyanika → kugwedezeka

Njira iyi imangochotsa mafuta owoneka bwino, ndikusambitsa kunja kwa± 15%(Njira yazitsulo yazitsulo imasungidwa mkati± 3%).

3.2 ma centn metch's zero-chilema "

• Kuwunikira pa intaneti: X-ray fluorescence (xrf) kusanthula kwa nthawi yeniyeni ya zinthu zotsalira (s, cl, etc.).
• Kuyeserera Kwakapitilira: Kusanthula Kwambiri200 ° C / 24hZoyenera kuonetsetsa kuti zero groser re-kutuluka.
• Kuchita Chilichonse: Mpukutu uliwonse umaphatikizaponso dzina la QR32 Njira Yofunika Kwambiri(mwachitsanzo, kutentha kwa kutentha, mphamvu za akupanga).

4. Kutsiliza: Chithandizo cha chigonjetso - maziko a kupanga zamagetsi zapamwamba

Chithandizo chambiri cha chinsalu cha Copper Copper sichinthu chongokweza koma kungoganiza zakuganiza zofunsira mtsogolo. Upangiri wa Chitsulo cha CivenChitsimikizo ChaumwiniwaKuchulukitsa Kwambiri (HDI), Mabwalo osinthika osinthika, ndi minda yomaliza.

Mu5g ndi Aira era, makampani okha ndi omwe amawerengaKuyeretsa Matekinolojeimatha kuyendetsa bwino kwambiri mtsogolo m'makampani apamkuwa a mkuwa.
