Nibihe bintu bigira ingaruka ku gukiza no gukama byamazi ya UV yo mu mazi

Hariho ibintu byinshi bigira ingaruka ku gukiza no gukama kwambikwa amazi ya Waterborne UV mugihe ukoresheje imashini ikiza UV.Uru rupapuro ruvuga gusa ibintu byingenzi.Ibi bintu birimo ibintu bikurikira:

1. Ingaruka zo gukama mbere ya sisitemu y'amazi kuri UV ikiza

Imiterere yo kumisha mbere yo gukira igira ingaruka zikomeye kumuvuduko wo gukira.Iyo itumye cyangwa ituzuye, umuvuduko wo gukira uratinda, kandi igipimo cya gelation nticyiyongera cyane hamwe no kwagura igihe cyo kwerekana.Ibi biterwa no gupakira hejuru.Nubwo amazi agira ingaruka runaka mukubuza polymerisiyumu ya ogisijeni, irashobora gusa gutuma ubuso bwa firime ya wino ikomera vuba, gusa bikagera kubutaka, ariko ntibugere no kumisha.Nka sisitemu irimo amazi menshi, sisitemu igengwa nubuziranenge hamwe nicyemezo mugihe gikiza ubushyuhe runaka.Hamwe no guhumeka vuba kwamazi hejuru ya firime ya wino, hejuru ya firime ya wino irakomera vuba, kandi amazi yo muri firime biragoye guhunga.Amazi menshi asigaye muri firime ya wino, bikarinda gukomeza guhuzwa no kwerekana firime ya wino no kugabanya umuvuduko wo gukira.Byongeye kandi, ubushyuhe bwibidukikije mugihe UV irrasiyo igira uruhare runini mugukiza ibishishwa bya UV.Ubushyuhe buri hejuru, nibyiza byo gukiza.Kubwibyo, niba gushyushya gukoreshwa, umutungo ukiza wa coating uzongerwaho kandi gufatira hamwe bizaba byiza.

2. Ingaruka ya fotoinitiator kuri Waterborne UV ikiza

Ifoto ya fotinitiator igomba kuba idahwitse hamwe na sisitemu yo gukiza UV ishingiye kumazi hamwe n’umuvuduko muke w’amazi, kugirango fotoinitiator ishobore gutatana, ibyo bikaba bifasha ingaruka zo gukira zishimishije.Bitabaye ibyo, mugihe cyo kumisha, fotoinitiator izahinduka hamwe numwuka wamazi, bikagabanya imikorere yabatangije.Amafoto atandukanye yo gupakira itabi afite uburebure butandukanye bwo kwinjiza.Gukoresha kwabo birashobora gukurura byimazeyo imirasire ya ultraviolet yuburebure butandukanye, bigahindura imishwarara ya ultraviolet, kandi byihutisha cyane gukira kwa firime ya wino.Kubwibyo, firime ya wino ifite umuvuduko wo gukira byihuse nibikorwa byiza birashobora kuboneka ukoresheje amafoto atandukanye kandi ugahindura igipimo cyamafoto atandukanye.Ibiri muri fotoinitiator yuzuye muri sisitemu bigomba gutezwa imbere neza, hasi cyane ntabwo bifasha amarushanwa yo kwinjiza hamwe na pigment;Umucyo mwinshi ntushobora kwinjira muburyo bwiza.Ku ikubitiro, igipimo cyo gukiza cya coating cyiyongera hamwe no kwiyongera kwifoto ya fotinitiator, ariko iyo ifoto ya fotoinitiator ikabije yiyongera ku gaciro runaka, hanyuma ikongera ibiyirimo, igipimo cyo gukira kizagabanuka.

3. Ingaruka ya UV ikiza amazi yo gukiza kuri UV ikiza

Amazi ashingiye ku mazi UV akenera gukenera gukenera ibintu byoroheje byoroheje byoroshye, bisaba ko molekile ya resin igomba kuba ifite amatsinda adahagije.Munsi yumucyo wumucyo ultraviolet, amatsinda adahagije muri molekile arahuzwa, kandi igifuniko cyamazi gihinduka igipfunsi gikomeye.Mubisanzwe, uburyo bwo kumenyekanisha acryloyl, methacryloyl, vinyl ether cyangwa allyl burakoreshwa kugirango resinike ya sintetike igire ibyemezo byuzuye mumatsinda, kuburyo ishobora gukira mubihe bikwiye.Acrylate ikoreshwa kenshi kubera ibikorwa byayo byinshi.Kuri sisitemu yo gukiza ya UV yubusa, hamwe no kwiyongera kubintu bibiri muri molekile, umuvuduko wo guhuza firime uziyongera, kandi umuvuduko wo gukira uzihuta.Byongeye kandi, ibisigarira bifite imiterere itandukanye bigira ingaruka zitandukanye kubipimo byo gukira.Igikorwa cyo kwitwara mumatsinda atandukanye akora muri rusange cyiyongera muburyo bukurikira: vinyl ether

4. Ingaruka ya pigment kuri UV ikiza ya Coatings ya Waterborne

Nkibintu bidafite amafoto muri Waterborne UV ikiza, pigment irushanwa nabayitangiza kugirango bakure urumuri rwa UV, bigira ingaruka cyane kubiranga sisitemu yo gukiza UV.Kubera ko pigment ishobora gukuramo igice cyingufu zimirasire, bizagira ingaruka kumikorere ya fotoinitiator kubikoresho byo kwinjiza urumuri, hanyuma bikagira ingaruka kumitekerereze ya radicals yubusa ishobora kubyara, bizagabanya umuvuduko wo gukira.Buri bara rya pigment rifite uburyo butandukanye (transmitance) kuburebure butandukanye bwumucyo.Gutoya kwinjirira kwa pigment, niko kwanduza kwinshi, kandi byihuse umuvuduko wo gukira wa coating.Carbone umukara ifite ubushobozi bwo kwinjiza ultraviolet no gukira buhoro.Ibara ryera rifite ibintu bikomeye byerekana, nabyo bikabuza gukira.Muri rusange, gahunda yo kwinjiza urumuri ultraviolet ni: Umukara> umutuku> Ubururu> cyan> Icyatsi> umuhondo> umutuku.

Umubare utandukanye hamwe nubunini bwa pigment imwe bigira ingaruka zitandukanye kumuvuduko ukiza wa firime ya wino.Ubwiyongere bwibigize pigment, igipimo cyo gukiza firime ya wino cyaragabanutse muburyo butandukanye.Ingano ya pigment yumuhondo igira uruhare runini mugukiza kwa firime ya wino, ikurikirwa na pigment itukura nicyatsi kibisi.Kuberako umukara ufite igipimo kinini cyo kwinjiza urumuri ultraviolet, bigatuma ihererekanyabubasha rya wino yumukara riba hasi cyane, ihinduka ryikigero cyacyo nta ngaruka zigaragara ku gipimo cyo gukiza cya firime ya wino.Iyo ingano ya pigment ari nini cyane, igipimo cyo gukira cyurwego rwo hejuru rwa firime ya wino cyihuta kuruta icy'isahani, ariko pigment iri murwego rwo hejuru ikuramo urumuri rwinshi rwa ultraviolet, bigabanya ihererekanyabubasha ryumucyo ultraviolet kandi bigira ingaruka ku gukira kurwego rwimbitse rwa firime ya wino, bikavamo hejuru yubuso bwa firime ya wino ikira ariko igice cyo hasi ntigikize, byoroshye kubyara "inkinko".
