M'mapangidwe amakono opanga mpikisano, opanga ambiri amalimbana ndi vuto lomwe limakhalapo: kukwaniritsa zomatira zodalirika pama polima osindikizira, zokutira, ndi zokutira. Kumamatira kukalephera, kumabweretsa kuwonongeka kwazinthu, zida zowonongeka, ndi kukonzanso kokwera mtengo. Pakati pa matekinoloje onse omwe alipo, chithandizo cha corona discharge ndi chimodzi mwa njira zogwiritsidwa ntchito kwambiri komanso zothandiza kwambiri-zodalirika ndi mafakitale padziko lonse chifukwa chakuchita bwino komanso kukwera mtengo kwake{3}}.
1. Njira Yoyambira: Kupanga Pulasitiki Yogwira Ntchito
Chithandizo cha Corona, pamtima pake, ndi njira yosavuta koma yamphamvu yosinthira pamwamba. Mosiyana ndi -mankhwala otsika a plasma omwe amafunikira mpweya wochepa, amagwira ntchito molingana ndi mpweya, zomwe zimapangitsa kuti zikhale zosavuta kugwirizanitsa ndi njira zomwe zilipo kale. Umu ndi momwe zimagwirira ntchito: mphamvu yamagetsi ikagwiritsidwa ntchito podutsa mpweya wodzaza ndi mpweya, imafulumizitsa tinthu tating'onoting'ono monga ma elekitironi ndi ayoni. Tinthu ting'onoting'ono timeneti timagundana ndi ma molekyulu a gasi amene sali nawo pa liwiro lalikulu, zomwe zimapangitsa kuti pakhale korona-yotsatizana ya mitundu yosiyanasiyana ya makemikolo, kuphatikizapo ma ayoni, ma elekitironi, ndi mpweya wa atomiki (wopangidwa ndi cheza cha UV pamene akutuluka).
Matsenga enieni amachitika pamene mitundu yogwira ntchito imeneyi, makamaka mpweya wa atomiki, imagwirizana ndi pulasitiki. Amachita ndi maatomu a haidrojeni ndi kaboni mu tcheni cha polima, ndikuyambitsa magulu a polar monga hydroxyl (-OH) ndi carbonyl (C=O) magulu. Kutsekemera kwa microscopic kumeneku ndi komwe kumapangitsa kuti kumamatira kutheke. Powonjezera mphamvu komanso kunyowa, magulu atsopanowa amalola pulasitiki kupanga ma hydrogen bond amphamvu ndi mphamvu za van der Waals zokhala ndi inki, zokutira, ndi zomatira-kusandutsa malo osamata{5}}kukhala omangika modalirika.
2. Kukhazikitsa kwaukadaulo ndi Kuwongolera Njira
Njira zochizira zamalonda za corona zimamangidwa kuti zigwirizane bwino ndi mizere yopangira, yomwe nthawi zambiri imagwiritsidwa ntchito pamzere pakutulutsa filimu kapena kusindikiza. Dongosolo lodziwika bwino limaphatikizapo -jenereta yokwera kwambiri, ma elekitirodi (omwe angakhale abwino, opanda pake, ochititsa chidwi, kapena AC), ndi rola yokhazikika yomwe gawo la pulasitiki limadutsa. Malo a ionization amakhala pafupi ndi electrode yogwira ntchito, ndipo mtundu wa ion wopambana (zabwino kapena zoipa) zimadalira polarity ya electrode.
Kusasinthasintha ndikofunikira pakuchiza bwino kwa corona, chifukwa chake kuwongolera ndikofunikira. Opanga amatha kusintha mphamvu yamankhwala{1}yotchedwa corona power{2}}kudzera pa control panel kuti ifanane ndi zinthu zapulasitiki ndi zotsatira zomwe mukufuna. Kuonjezera apo, nthawi yomwe gawo lapansi limathera kumalo ochiritsira (nthawi yokhalamo), yoyendetsedwa ndi liwiro la conveyor (yosinthika ndi ma frequency converter), iyenera kuyesedwa mosamala. Mufunika kutsegula kokwanira kuti muwongolere kumamatira, koma osati kwambiri moti zimawononga pulasitiki. Njira imeneyi imaonedwa kuti ndiyofunika kwambiri chifukwa imapangitsa kuti thupi lizigwira ntchito-kupangitsa kuti pakhale mawonekedwe owoneka bwino komanso owoneka bwino omwe amalimbitsa zomata.
3. Ntchito Zamakampani ndi Kuchuluka Kwazinthu
Kuchiza kwa Corona ndikofunikira kuti mapulasitiki akhale omangika, makamaka zida za hydrophobic zomwe mwachilengedwe zimakhala zovuta kutsatira. Amagwiritsidwa ntchito kwambiri m'mafakitale onyamula, osindikizira, ndi a nsalu. Kwa mafilimu apulasitiki ndi zojambulazo, zimatsimikizira kusindikizidwa kwabwinoko, kulimba kolimba, ndi kuwongolera bwino kwa zotchingira zotchingira -kuchepetsa kuwonongeka ngati kusenda kapena matuza. Popanga nsalu, nsalu zopangira monga poliyesitala ndi polypropylene (zodziwika bwino kuti ndizovuta kuzidaya) zimapeza chithandizo cha corona kuti chikhale cholandirika ndi inki ndi kumaliza.
Ngakhale kuti zimagwira ntchito bwino kwa ma polyolefin ambiri ndi ma polima wamba, chithandizo cha corona silingo umodzi{-chokwanira-zonse. Zochepa kwambiri-pamwamba-zida zopangira mphamvu monga fluoroplastics zingafunike chithandizo chamankhwala champhamvu kwambiri kapena chapadera. Koma pamafakitale ambiri-pazinthu monga polyethylene, polypropylene, ndi filimu za poliyesitala{8}}mankhwala a corona ndi okwera mtengo-njira yodalirika, yodalirika. Ntchito yake ndiyabwino kwambiri-yakhazikitsidwa mwakuti msika wa dielectric barrier discharge (DBD) applications (omwe amaphatikizapo chithandizo cha corona) ukukulirabe, chifukwa cha kufunikira kosalekeza kwa malo apulasitiki ogwiritsiridwa ntchito.
4. Njira Zoganizira Kulera Ana
Kwa oyang'anira zogula ndi mainjiniya omwe akufuna kutengera ukadaulo uwu, kumvetsetsa mfundo zoyambira ndi gawo loyamba. Kusankha wopereka chithandizo choyenera cha corona sikungokhudza mtengo chabe{1}ndi za chithandizo chaukadaulo, kudalirika kwa makina, komanso kuthekera kopereka chithandizo chokhazikika. Izi ndi zofunika kwambiri posunga khalidwe la kupanga. Chithandizo cha Corona chimagwiranso ntchito bwino ngati njira yopangira chithandizo, nthawi zambiri kumatsatira kuyeretsa koyambira kapena kuchotsera mafuta, kuti pulasitiki ikhale yokonzeka kuti igwirizane bwino.
Mapeto
Chithandizo cha Corona papulasitiki ndi chosavuta koma champhamvu pochita: chimagwiritsa ntchito mphamvu yamagetsi kupanga madzi am'mlengalenga omwe amasintha magawo apamwamba a pulasitiki. Powonjezera magulu a polar, amasintha malo ongokhala,{1}}osamata kuti akhale okhazikika, ogwirizana. Pamene ma polima akusintha kuti akwaniritse zofuna zamakampani atsopano-kuchokera ku zida zokhazikika mpaka pakuyika zida zapamwamba-kudziŵa bwino ndi kukhathamiritsa chithandizo cha corona kumakhalabe kofunika pa ntchito iliyonse yosindikiza, zokutira, kapena zomangira zinthu zapulasitiki. Si luso chabe; ndi njira kuonetsetsa kusasinthasintha khalidwe ndi kuchepetsa zinyalala kupanga.
