Mercury Vapor Mwenje
Ose maviri electrode arc mwenje uye electrode-shoma microwave marambi anowira mukati mechikamu chemercury vapor. Mercury vapor mwenje imhando yepakati-kudzvanywa, gasi-inoburitsa marambi umo diki diki elemental mercury uye inert gasi inoputirwa muplasma mukati meyakavharwa quartz chubhu. Plasma igasi rakanyanya kudziya ionized rinokwanisa kufambisa magetsi. Iyo inogadzirwa nekuisa magetsi emagetsi pakati pemaelectrode maviri mukati mearc rambi kana ne microwaving mwenje-isina electrode mukati meyakavharirwa kana mhango yakafanana nepfungwa kune imba microwave oveni. Kana yave vaporized, mercury plasma inoburitsa yakafara-spectrum mwenje paultraviolet, inooneka, uye infrared wavelengths.
Kana iri mwenje wearc yemagetsi, magetsi akaiswa anosimbisa iyo yakavharwa quartz chubhu. Iri simba rinonyungudutsa mecury kuita plasma uye rinoburitsa maerekitironi kubva mumaatomu akafukidzwa. Chikamu chemaerekitironi (-) chinoyerera chakananga mwenje tungsten electrode yakanaka kana anode (+) uye muUV system yemagetsi dunhu. Maatomu ane maerekitironi achangobva kushaikwa anova ma cations ane simba (+) anoyerera akananga kune rambi rinochajiwa zvisina kunaka tungsten electrode kana cathode (-). Pavanenge vachifamba, maatomu anorova maatomu asina kwaakarerekera mumusanganiswa wegasi. Mhedzisiro inotamisa maerekitironi kubva kumaatomu asina kwaakarerekera kuenda kumakesheni. Sezvo ma cations anowana maerekitironi, anodonhera munzvimbo ine simba rakaderera. Musiyano wesimba unoburitswa semafotoni anopenya kunze kubva kuchubhu yequartz. Kana mwenje uchibatidzwa zvakanaka, wakatonhodzwa zvakanaka, uye uchishanda mukati mehupenyu hwayo hunobatsira, kugara uchipihwa kwemakesheni achangobva kugadzirwa (+) anokwevera akananga kune negative electrode kana cathode (-), achirova mamwe maatomu uye achigadzira inoenderera kuburitsa kweUV mwenje. Marambi eMicrowave anoshanda nenzira yakafanana kunze kwekuti ma microwaves, anozivikanwawo seredhiyo frequency (RF), anotsiva dunhu remagetsi. Sezvo marambi emicrowave asina tungsten electrodes uye angori akavharirwa quartz chubhu ine mercury uye inert gasi, anowanzo kunzi electrodeless.
Iyo UV inobuda yebroadband kana yakafara-spectrum mercury vapor marambi inotambanudzira ultraviolet, inooneka, uye infrared wavelengths, muhupamhi hwakaenzana. Chikamu cheultraviolet chinosanganisira musanganiswa weUVC (200 kusvika 280 nm), UVB (280 kusvika 315 nm), UVA (315 kusvika 400 nm), uye UVV (400 kusvika 450 nm) wavelengths. Marambi anoburitsa UVC mumawavelength ari pasi pe240 nm anogadzira ozone uye anoda kupera simba kana kusefa.
Iyo spectral inobuda ye mercury vapor rambi inogona kuchinjwa nekuwedzera madiki madopants, akadai se: iron (Fe), gallium (Ga), lead (Pb), tin (Sn), bismuth (Bi), kana indium (Indium). ) Masimbi akawedzerwa anoshandura kuumbwa kweplasma uye, nekudaro, simba rinoburitswa kana cations inowana maerekitironi. Marambi ane simbi yakawedzerwa anonzi doped, additive, uye metal halide. Mazhinji maIngi akagadzirwa neUV, machira, anonamira, uye maextrusions akagadzirwa kuti aenderane nekubuda kweimwe standard mercury- (Hg) kana iron- (Fe) doped marambi. Marambi eIron-doped anochinja chikamu chekubuda kweUV kuenda kureba, pedyo-inooneka wavelengths, izvo zvinoguma nekupinda zvirinani kuburikidza neakakora, ane pigmented formulations. Magadzirirwo eUV ane titanium dioxide anorapa zvirinani nemarambi egallium (GA). Izvi zvinodaro nekuti marambi egallium anochinja chikamu chakakosha chekubuda kweUV kuenda kune wavelengths kureba kupfuura 380 nm. Sezvo titanium dioxide inowedzerwa kazhinji isingatore chiedza pamusoro pe380 nm, kushandisa gallium marambi ane chena maumbirwo anobvumira akawanda UV simba kutorwa nemafotoinitiators kusiyana nezvinowedzerwa.
Spectral profiles inopa vanogadzira uye vanopedzisa vashandisi vane inomiririra inomiririra yekubuda kweradiated yeimwe rambi dhizaini inogovaniswa pane iyo electromagnetic spectrum. Ipo vaporized mercury uye simbi dzekuwedzera dzakatsanangura hunhu hwemwaranzi, musanganiswa chaiwo wezvinhu uye inert magasi mukati mequartz chubhu pamwe nekuvaka mwenje uye kurapa system dhizaini zvese zvinopesvedzera kubuda kweUV. Iyo spectral inobuda yerambi risina kubatanidzwa rinoshandiswa uye kuyerwa nemutengesi wemwenje mumhepo yakazaruka ichava nemhando yakasiyana-siyana ye spectral pane mwenje wakaiswa mukati memusoro werambi wakanyatsogadzirirwa kuratidza uye kutonhora.

Sekondari yekugovera masosi kazhinji yakadzoreredza mwenje kubva kumuenzaniso, uye makopi anogona kunge asina iwo akafanana ekupedzisira akakodzera, quartz dhayamita, mecury zvirimo, kana gasi musanganiswa, izvo zvinogona kukanganisa kubuda kweUV uye kugadzirwa kwekupisa. Kana chizvarwa chekupisa chisina kuenzana nekutonhora kwehurongwa, mwenje unotambura mune zvese zvinobuda uye hupenyu. Marambi anotonhorera anoburitsa UV shoma. Marambi anopisa zvakanyanya haagare kwenguva refu uye anotenderera patembiricha yepamusoro.
Hupenyu hwemarambi e-electrode arc anoganhurirwa netembiricha yerambi rekushanda, nhamba yemaawa ekumhanya, uye nhamba yekutanga kana kurohwa. Nguva imwe neimwe mwenje painorohwa ne-high-voltage arc panguva yekutanga, zvishoma zve tungsten electrode inopera. Pakupedzisira, rambi harizobatizve. Marambi eElectrode arc anosanganisira zvivharo zvevhavha izvo, kana zvabatanidzwa, zvinovharira UV kubuda seimwe nzira yekudzokorora kuchovha simba remwenje. Ingi dzakawanda dzinoshanda, mapeji, uye zvinonamira zvinogona kuguma nehupenyu hwerambi hurefu; nepo, zvishoma reactive formulations zvingada kakawanda rambi kuchinja.
UV-LED masisitimu anogara akareba kupfuura akajairwa marambi, asi UV-LED hupenyu hausiwo mhedziso. Sezvinoita marambi akajairwa, maLED LED ane miganhu mukuoma kwaanogona kufambiswa uye kazhinji anofanirwa kushanda nematembiricha ari pasi pe120 ° C. Kunyanya-kutyaira maLED uye pasi-kutonhora maLED anozokanganisa hupenyu, zvichikonzera kukurumidza kushatisa kana kutadza kwakaipisisa. Havasi vese UV-LED sisitimu vatengesi parizvino vanopa zvigadziriso zvinosangana nepamusoro-soro hupenyu hwakasimba kupfuura maawa makumi maviri. Izvo-zvakagadzirwa uye zvakachengetwa masisitimu zvichagara kupfuura maawa e20,000, uye yakaderera masisitimu ichakundikana mukati madiki-mapfupi mahwindo. Nhau dzakanaka ndedzekuti madhizaini e LED anoramba achivandudza uye anogara kwenguva refu nega yega dhizaini iteration.
Ozon
Kana mapfupi eUVC mafungu akakanganisa mamorekuru eokisijeni (O2), anoita kuti mamorekuru eokisijeni (O2) aparadzane kuita maatomu maviri eokisijeni (O). Maatomu eokisijeni emahara (O) anobva adhumhana nemamwe mamorekuru eokisijeni (O2) ogadzira ozone (O3). Sezvo trioxygen (O3) isinganyanyi kugadzikana padanho repasi pane dioxygen (O2), ozone inodzokera nyore nyore kumorekuru weokisijeni (O2) neatomu reokisijeni (O) sezvainonyura nemhepo yemuchadenga. Maatomu eokisijeni emahara (O) obva abatana zvakare mukati meiyo exhaust system kugadzira mamorekuru eokisijeni (O2).
Kumaindasitiri eUV-kuporesa maapplication, ozone (O3) inogadzirwa kana okisijeni yemuchadenga ichipindirana neultraviolet wavelengths pazasi 240 nm. Broadband mercury vapor-curing sources inoburitsa UVC pakati pe200 ne280 nm, iyo inodarika chikamu chenzvimbo inogadzira ozone, uye marambi eexcimer emit vacuum UV pa172 nm kana UVC pa222 nm. Ozone yakagadzirwa ne mercury vapor uye excimer mwenje mwenje haina kugadzikana uye haisi yakakosha kunetseka kwezvakatipoteredza, asi zvinodikanwa kuti ibviswe kubva munzvimbo yakatenderedza vashandi nekuti inoshatisa kufema uye ine chepfu pamazinga akakwirira. Sezvo inoshambadzira UV-LED yekurapa masisitimu inoburitsa UVA kubuda pakati pe365 ne405 nm, ozone haina kugadzirwa.
Ozone ine hwema hwakafanana nekunhuhwirira kwesimbi, waya inopisa, chlorine, uye spark yemagetsi. Manzwiro emunhu anogona kuona ozone yakaderera se 0.01 kusvika 0.03 zvikamu pamiriyoni (ppm). Kunyange zvichisiyana nemunhu uye nhanho yebasa, kutarisisa kwakakura kupfuura 0.4 ppm kunogona kutungamira kune yakaipa kufema mhedzisiro uye kutemwa nemusoro. Kufefetedza kwakaringana kunofanirwa kuiswa pamitsara yeUV-inoporesa kuderedza kuratidzwa kwevashandi kune ozone.
UV-ekurapa masisitimu anowanzo kugadzirwa kuti ave nemhepo yekuburitsa sezvo ichisiya misoro yemwenje kuitira kuti ibviswe kure nevashandisi uye kunze kwechivako uko kwainowora mukuvapo kweokisijeni nechiedza chezuva. Neimwe nzira, marambi asina ozone anosanganisira quartz yekuwedzera iyo inovhara ozone-inogadzira wavelengths, uye zvivakwa zvinoda kudzivirira maburi kana kucheka maburi padenga anowanzo shandisa mafirita pakubuda kwemafeni emhepo.
