Kumamatira kosakhazikika pambuyo pa chithandizo cha corona ndi nkhani yodziwika bwino komanso yovuta yokhudza zida, njira, zida, ndi chilengedwe.
Lingaliro Lachikulu: Kumamatira Kosakhazikika=Kutayika kwa Njira Yowongolera Parameter
Kuti athetse kusakhazikikaku, chithandizo cha corona chiyenera kusinthidwa kuchoka pa "bokosi lakuda" kukhala njira yoyezera, yowunikira, komanso yobwerezabwereza.
Gawo 1: Kuwongolera Molondola kwa Electrode ndi Discharge System (Magwero)
Electrode ndi discharge system control ndiye gwero lodziwika bwino koma losaiwalika losakhazikika. Poyeretsa ndi kukonza ma elekitirodi, ma elekitirodi (makamaka pa silikoni zodzigudubuza) amakonda kusonkhanitsa ozoni, fumbi, zowonjezera zowonjezera monga zotsekemera, ndipo zimatha kuchotsedwa ndi sparks zamagetsi; wosanjikiza woyipitsidwa uwu umapanga chotchinga chotchinga, chomwe chimatsogolera ku mphamvu zotulutsa zosagwirizana, "corona yofooka" kapena kutsekeka, komanso kusokoneza chithandizo chamankhwala. Kuti izi zitheke, njira zoyeretsera zimayenera kukonzedwa-ma electrode ndi zodzigudubuza pansi ziyenera kutsukidwa bwino ndi ethanol ya anhydrous kapena isopropanol nthawi iliyonse isanakwane kapena kupanga tsiku lililonse, kupewa silikoni kapena mafuta-okhala ndi nsalu. Kuonjezera apo, kuyang'ana nthawi zonse pamavalidwe a ma elekitirodi ndikofunikira kuti muyang'ane maenje, dzimbiri, kapena kupindika, chifukwa maelekitirodi owonongeka amachititsa kuti magetsi awonongeke, arcing, ndi filimu yowonongeka, ndikuwonetsetsa kuti ma electrode parallelism ndi kofunika kwambiri kuti pakhale kusiyana kosasinthasintha pakati pa electrode yonse{5}}m'lifupi mwake, chifukwa kusalinganika kumapangitsa kuti chithandizo chisakhale chofanana. Ponena za makina ochizira matenda a corona, kukalamba kwa zida, kutulutsa mphamvu kwa magetsi osakhazikika, ndi kutsika kwamphamvu-kuchuluka kwa magwiridwe antchito a jenereta ndizofala; Njira zothetsera mphamvu zimaphatikizapo kuyeza mita yamagetsi yamagetsi pafupipafupi kuti muwonetsetse kuti mphamvu yowonetsedwa ikufanana ndi zomwe zimatuluka (kumayang'ana mphamvu mu watts/mphindi/cm² osati voteji kapena yapano) komanso kuyang'ana silikoni kapena zodzigudubuza zina kuti zitsimikizire kuti zili bwino popanda ming'alu kapena ukalamba wamba kuti asawonongeke.
Gawo 2: Kukhazikika ndi Kukhathamiritsa kwa Parameters (Core)
Kungoti "kuyatsa korona" sikukwanira, chifukwa kuwongolera moyenera magawo onse azinthu ndikofunikira. Kwa ma critical process parameters (CPP), chithandizo cha mphamvu sichifukwa chakuti "chapamwamba chiri bwino"{1}}kuchepa mphamvu kumapangitsa kuti munthu asamadwale-mankhwala, pamene kupitirira{3}}mankhwala amawononga unyolo wa mamolekyu a pamwamba ndi kuchepetsa kugwirizana, kotero kuyesa kwa gradient kuyenera kuchitidwa kuti apeze zenera lamphamvu lachinthu chilichonse. Kuthamanga kwa mankhwala ndi mphamvu zimagwirizanitsidwa kwambiri, ndi liwiro lachangu kutanthauza nthawi yochepa yotulutsa ndipo motero mphamvu yowonjezereka yofunikira; ziwirizi ziyenera kuyendetsedwa motsatirana kuti pakhale mphamvu yokhazikika yapamtunda (mtengo wa dyne) woposa pang'ono inki kapena zomatira, monga 42-44 mN/m m'malo mwa 38 mN/m chabe. Kusiyana kwa ma elekitirodi kuyenera kusungidwa pamtengo wokhazikika (monga 1.5-2.0mm) ndipo kusasinthidwe mwachisawawa, chifukwa kusiyanako kumakhudzanso mphamvu ya magetsi. Pankhani ya kuwongolera chilengedwe, kutentha kozungulira ndi kutentha kumakhudza kutulutsa mpweya - mpweya wonyowa umayenda bwino, kotero kuti malo ochitira msonkhano akhazikike, ndipo mphamvu iyenera kukonzedwa bwino m'nyengo yachinyezi ngati nyengo yamvula. Pakalipano, kuziziritsa kogwira mtima kwa maelekitirodi ndi zodzigudubuza kuyenera kuwonetseredwa kuti zisawonongeke kutentha, zomwe zimasokoneza mgwirizano wa chithandizo ndi moyo wa zipangizo.
Gawo 3: -Mwakuya Kumvetsetsa ndi Kusintha kwa Zinthu Pazokha (Zofunika)
Zida ndizomwe zimayambitsa zovuta kumamatira, ndi chithandizo cha corona chomwe chimakhala ngati dalaivala wakunja, chifukwa chake zinthu zakunja zitha kuchitika kudzera mkati. Kuipitsidwa kwa gawo lapansi ndizomwe zimayambitsa kusakhazikika kosakhazikika: otsika otsika a maselo olemera (LLM) monga othandizira (erucamide, oleamide) mu PE ndi antistatic agents mu PP amasamukira kumtunda panthawi yopanga ndi kusungirako, kupanga "filimu yodzipatula" yosaoneka; zotsalira za zothandizira kukonza monga mafuta odzola ndi zotulutsa nkhungu, komanso kuipitsidwa kosungirako monga fumbi ndi madontho amafuta, zimathandizanso. Njira zothetsera mavuto zikuphatikizapo kulankhulana ndi ogulitsa kuti apemphe-kusamuka kapena kusamuka{3}}magiredi otsika kwambiri osamuka, kugwiritsa ntchito "woyamba{4}}kulowa, choyamba-kutuluka" kuti muchepetse kusamuka kwa ozembera, kuwonjezera njira zoyeretsera pa intaneti (mwachitsanzo, plasma air knife, electrostatic brush) kusamuka komwe kulipo, ndikuyesa cholembera cha dyne pa mpukutu uliwonse wa filimu kapena batch pakuwunika komwe kukubwera kuti alembe zoyambira. Mitundu yosiyanasiyana ya madera ndi polarities imayankha mosiyana ndi chithandizo cha corona-zosakhala{10}}zida zokhala ndi polar monga PE ndi PP zimakhala ndi mphamvu ya corona mphamvu koma zimafupikitsa mwachangu, pomwe zida za polar monga PET, PA, ndi PVC zili ndi polarity yokhazikika yomwe imatsimikizira chithandizo chokhalitsa koma chitha kufuna mphamvu zambiri kuti iyambike. Mayankho ofananira amakhudza kukhazikitsidwa kwa magawo (kugwiritsa ntchito mphamvu yotsika ya PE / PP ndikuwunika "zenera la nthawi" kunjira zotsatizana, komanso mphamvu yowonjezereka yoyambitsa PET) ndikumvetsetsa malamulo ochepetsera mphamvu pakuzindikira ma curve a dyne value attenuation poyeserera kuwonetsetsa kuti mphamvu yakumtunda imakhalabe pamwamba pazipinda zotetezeka panthawi yoyatsira kapena kusindikiza. Kuphatikiza apo, inki kapena zomatira zosagwirizana zimatha kusokoneza chithandizo chabwino kwambiri cha corona, motero kuyesa kogwirizana (kuchita zoyezetsa zomatira monga -zoyesa zomatira ndi tepi pogwiritsa ntchito ma corona{14}zigawo zomatira posankha inki ndi zomatira) ndizofunikira, komanso kuti zikhale zovuta kuphatikiza zomatira (monga madzi{17}pogwiritsa ntchito inki ya BOPP) corona attenuation, kugwiritsa ntchito kachidutswa kakang'ono koyambira{18}}coona ngati "mlatho wosanjikiza" kungalimbikitse kukhazikika kwa zomatira.
Gawo 4: Khazikitsani-Njira Yoyang'anira Kayendedwe Kabwino (Chitsimikizo)
Mfundo yakuti "palibe kuyeza, kusayang'anira" ikugogomezera kufunikira kokhazikitsa-njira zonse zowunikira khalidwe. Kuti mugwiritse ntchito kuyang'anira pa intaneti, kukhazikitsa chojambulira pa intaneti cha dyne value detector n'kwabwino, chifukwa chimathandiza kuti{2}}muzitha kuyang'anira filimu nthawi zonse{3}}ndi ma alarm pamene mtengo utsika, zomwe ndi zofunika kwambiri kuti musatseke{4}} loop control. Kulimbitsa kuyesa kwapaintaneti kumafuna kugwira ntchito mokhazikika poyesa cholembera kapena kuyesa mayankho kumayambiriro kwa mpukutu uliwonse, panthawi yopanga, komanso posintha mipukutu, komanso kujambula mosamalitsa ndi kutsata -kulemba katundu, nambala ya batch, magawo ochizira (mphamvu/liwiro), chisanadze ndi positi{7}}mankhwala opangira ma dyne pazovuta zilizonse, zomwe zimafunikira pakuyesa. Kutsimikizira komaliza kumaphatikizapo kuyesa zowononga nthawi zonse monga kuyesa-kudula ndi kusenda mphamvu kuti mutsimikize kuti kumamatira komaliza kumakwaniritsa zofunikira.
