Nkhani Yachikulu: Zowonetsera ndi Zomwe Zimayambitsa Kusauka kwa Corona Chithandizo
Mawonetseredwe: Kumamatira kosindikiza kosakwanira, kuyanika, kuyanika mphamvu, kutsika kwapamtunda (kulephera kwa cholembera cha dyne).
Choyambitsa: Kusakwanira kwamphamvu pamwamba pazinthu. Chithandizo cha Corona chimatulutsa mpweya kudzera-kafupipafupi komanso{2}}kutuluka kwamphamvu kwambiri kuti apange ozone ndi plasma. -zigawo zamphamvu zamphamvuzi (monga PE, PP, BOPP), zomwe zimapangitsa kuti makutidwe ndi okosijeni ndi ma etching, potero zimawonjezera mphamvu yapamtunda ndi kulimbikitsa kulumikizana ndi inki ndi zokutira.
Maupangiri Opangira Magawo Atatu a Core
1. Mphamvu - "Kulimba" kwa Chithandizo
Parameter Tanthauzo: Mphamvu zotulutsa zamakina ochizira corona, nthawi zambiri amakhala ma kilowatts kapena ma watts pa centimita. Zimatsimikizira mwachindunji mphamvu yotulutsa.
Chikoka Lamulo:
Mphamvu Zosakwanira: Mphamvu zosakwanira zotulutsa mphamvu zimalephera kutsegulira bwino maunyolo a maselo pazakuthupi, zomwe zimapangitsa kuti pakhale kufooka kwamankhwala komanso kuwongolera kwakanthawi kochepa.
Mphamvu Zochulukira: Zingayambitse "kusokonekera" kapena "kupitilira-mankhwala". Kuchiza-kuchiza kumawononga zinthu, kumaphwanya unyolo wa mamolekyu, kumachepetsa mphamvu, ngakhale kutulutsa fungo (zonyezimira za ozoni), kapena kutsekereza (kumatira kuseri kwa mpukutu wina wa zinthu).
Maupangiri Oyitanira:
Kuchokera Pansi mpaka Pamwamba: Mukakonza zinthu zatsopano kwa nthawi yoyamba, yambani ndi mphamvu zochepa ndikuwonjezera pang'onopang'ono.
Yang'anani Ma Electrodes: Malo abwino otulutsira ndi yunifolomu yofiirira korona pakati pa elekitirodi ndi chodzigudubuza, limodzi ndi phokoso lokhazikika komanso losalekeza la "kuombeza". Ma arcs oyera owala (kuthwanima) amawonetsa mphamvu zochulukirapo kapena zoipitsidwa/zowonongeka maelekitirodi/magawo amagetsi.
Reference Standard: Kwa mafilimu wamba apulasitiki (mwachitsanzo, BOPP, CPP, PE), kachulukidwe ka mphamvu nthawi zambiri amakhala pakati pa 1.5 ~ 3.0 W/cm². Mutha kuyamba kuyesa kuchokera pakatikati pamtunduwu (mwachitsanzo, 2.0 W/cm²).
2. Kuthamanga - "Nthawi" ya Chithandizo
Parameter Tanthauzo: Kuthamanga kwa mzere wazinthu zomwe zimadutsa pansi pa electrode yochizira corona.
Chikoka Lamulo:
Kuthamanga Kwambiri: Zinthuzi zimakhala pamalo okhetserako kwakanthawi kochepa kwambiri, zomwe zimapangitsa kuti pasakhale kuphulika kokwanira-kuchuluka kwa tinthu tating'onoting'ono komanso kusamalidwa bwino.
Kuthamanga Kwambiri Kwambiri: Kulandira chithandizo kwanthawi yayitali kumabweretsa-mankhwala opitilira muyeso (makamaka amphamvu kwambiri), kuwononga mphamvu komanso kuwononga zinthuzo.
Maupangiri Oyitanira:
Kulumikizana ndi Mphamvu: Mphamvu ndi liwiro ndizogwirizana kwambiri. Mwachidule: Zotsatira za Chithandizo ≈ Mphamvu / Kuthamanga. Kupititsa patsogolo zotsatira, mwina "kuwonjezera mphamvu" kapena "kuchepetsa liwiro".
Yang'anani Kukonzekera Kwachangu ndi Kukonza Mphamvu: Popanga, kuti mugwire bwino ntchito, nthawi zambiri mumadziwa liwiro loyenera kupanga, ndiyeno sinthani mphamvu kuti igwirizane ndi liwiro ili kuti mukwaniritse chithandizo chofunikira.
Njira Yoyesera: Konzani mphamvu ndi mtunda, pang'onopang'ono muwonjezere liwiro, ndikuyesani ndi cholembera cha dyne kuti mupeze liwiro lalikulu lomwe lingathe kufika pamtunda wofunikira (mwachitsanzo, 38 dynes), yomwe ndi malo opangira kwambiri.
3. Kutalikirana - "Kukhazikika" kwa Chithandizo
Parameter Tanthauzo: Kusiyana pakati pa electrode ndi chodzigudubuza cha corona, kapena mtunda kuchokera pa electrode kupita kuzinthu zakuthupi (malingana ndi mtundu wa makina).
Chikoka Lamulo:
Utali Wautali Kwambiri: Mphamvu yamagetsi imafowoka, kutulutsa kwa corona kumabalalika, ndipo mphamvu sizingathe kuchitapo kanthu pazakuthupi, kuchepetsa mphamvu yamankhwala.
Mtunda Waufupi Kwambiri: Mphamvu yamagetsi yamagetsi ndi yokwera kwambiri, imakoka mosavuta ma arcs, kuswa kapena kuwotcha filimuyo, ma electrode owononga ndi zigawo za dielectric, zomwe ndizoopsa kwambiri.
Maupangiri Oyitanira:
Tsatirani Buku la Zida: Mtunda nthawi zambiri umakhala woyamba kukhazikitsidwa ndipo suyenera kusinthidwa mosavuta mukangokhazikitsidwa. Mitundu yosiyanasiyana yamakina ndi kapangidwe ka ma elekitirodi ali ndi mipata yoyenera (mwachitsanzo, 1.5-3.0mm).
Onetsetsani Kufanana: Pamene mukukonzekera mtunda, ndikofunikira kuonetsetsa kuti kusiyana pakati pa electrode yonse ndi roller ndi yofanana; apo ayi, zotsatira za mankhwala zidzakhala zamphamvu pamapeto amodzi ndi zofooka pa zina.
Zabwino-Mfundo Yochunira: Ngati kusintha mphamvu ndi liwiro kuti lifike malire sikungakwanitse, mutha kuyesa bwino-kusintha mtunda pakati pa mtunda wololedwa ndi wopanga. Kuchepetsa mtunda kumatha kupititsa patsogolo chithandizo, koma kuyenera kuchitidwa mosamala kwambiri kuti zisayambike.
Ngati mayesowo akulephera mutatha kuwonjezera liwiro, sinthani kubwereranso ku liwiro lapachiyambi kapena onjezerani pang'ono mphamvu kuti mugwirizane ndi liwiro latsopano.
Chidziwitso chofunikira: Pambuyo pakusintha kulikonse, dikirani kuti theka la mpukutu wazinthu udutse musanayesedwe. Chifukwa chithandizo chamankhwala cha corona chimakhala ndi nthawi yayitali komanso kudzikundikira, zotsatira za kuyezetsa mwachangu sizolondola.
Zinthu Zina Zomwe Zimagwira Ntchito
Zofunika Pazokha: Mitundu yosiyanasiyana ya ma masterbatches ndi zowonjezera (mwachitsanzo, ma slip agents) zimakhudza kwambiri momwe chithandizo chimakhudzira komanso kuchuluka kwa kuchepa.
Ukhondo wa Ma Electrodes ndi Dielectric Layers: Ma elekitirodi ndi zovundikira dielectric zokutidwa ndi fumbi, madontho amafuta, kapena ma oxides zimalepheretsa kutulutsa ndipo ziyenera kutsukidwa nthawi zonse ndi mowa, ndi zina zambiri.
Kutentha Kwambiri ndi Chinyezi: Kutentha kwa mpweya wambiri kumakhudza makhalidwe otuluka; malo ochitira misonkhano ayenera kukhala okhazikika.
Nthawi Yake Pambuyo pa Chithandizo: Zotsatira za chithandizo cha corona zimachepa pakapita nthawi (makamaka akanema okhala ndi ma slip agents), ndipo kusindikiza kapena kuyika kuyenera kumalizidwa mkati mwa maola 24 mutalandira chithandizo.
Chidule Chachidule: Choyamba konzani mtunda kuti muwonetsetse kufanana, kenako konzani liwiro ndikuwongolera mphamvu, tsimikizirani ndi kuyesa kwa dyne pen, chabwino-konza malire kuti mutsimikizire kukhazikika.
Pokonza mwasayansi ndi mogwirizana magawo atatuwa, mutha kuthana ndi vuto la kudwala kwa corona komanso kupanga-zabwino kwambiri komanso zogwira mtima.
