Hukama huripo pakati pemafungu emumuromo weprinta yeUV neinki yeUV ndehwekuti: mafungu anoenderana neinki dzakasiyana akasiyanawo, izvo zvinonyanya kukanganiswa nekusiyana kwekumhanya kweruzha rweinki, viscosity yeinki, uye density yeinki. Mazhinji emaprinta aripo iye zvino ane mafungu anochinjika kuti aenderane neinki dzakasiyana.
Basa refaira remushonga wemuromo: faira remushonga wemuromo inguva yekuita kuti ceramic yemushonga wemuromo wepamuromo ishande, kazhinji kune mupendero unokwira (nguva yekudzvanya), nguva yekudzvanya inoenderera mberi (nguva yekudzvanya), mupendero unodonha (nguva yekuburitsa mupendero), Nguva yakasiyana yakapihwa ichachinja madonhwe einki anodzvanywa nemushonga wemuromo.
1.Nheyo dzeKugadzira Mafungu eDhizaini
Dhizaini yeDrive waveform inosanganisira kushandiswa kwenheyo yezvikamu zvitatu zvemafungu. Amplitude, frequency uye phase zvinokanganisa mhedzisiro yekupedzisira yepiezoelectric sheet. Hukuru hweamplitude hune simba pakumhanya kwedonhwe reinki, izvo zviri nyore kuziva uye kunzwa, asi simba refrequency (wavelength) pakumhanya kwedonhwe reinki harisi rechokwadi. Kazhinji, iyi shanduko ye curve ine peak yepamusoro (yakanyanya kukosha). Kukosha kwakanakisa) hakusi kwekusarudza, saka kukosha kwakanakisa kunofanirwa kusimbiswa zvichienderana nehunhu hwakasiyana hweinki pakushandiswa chaiko.
2. Simba rekumhanya kweink pa waveform
Kazhinji inokurumidza kupfuura inki inorema. Kumhanya kweruzha rweinki inobva mumvura kwakakura kupfuura kweinki inobva mumafuta. Pamusoro mumwe chete wekudhinda, kana uchishandisa huwandu hwakasiyana hweinki, urefu hwakakodzera hwewavelength muchimiro chayo chewavelength hunofanira kugadziriswa. Semuenzaniso, upamhi hwewavelength yeinki inobva mumvura inofanira kunge iri diki pane hweinki inobva mumafuta.
3. Simba reinki pakupenya kwemvura (waveform)
Kana printa yeUV ikadhindwa mu multi-point mode, mushure mekunge waveform yekutanga yapera, inoda kumira kwechinguva yozotumira waveform yechipiri, uye kana waveform yechipiri yatanga zvinoenderana nekutenderera kwechisikigo kwe nozzle surface pressure mushure mekunge waveform yekutanga yapera. Shanduko yacho inongoora kusvika pa zero. (Kusiyana kwe inki viscosity kuchakanganisa nguva ino yekuora, saka ivimbiso yakakosha ye stable ink viscosity kuti ive nechokwadi chekudhinda kwakasimba), uye zviri nani kubatana kana phase iri zero, zvikasadaro wavelength ye wave yechipiri ichachinjwa. Kuti ive nechokwadi chekuti inkjet yakajairika, inowedzerawo kuoma kwekugadzirisa waveform yakanakisa ye inkjet.
4.Simba rekuwanda kweinki pachimiro chewaveform
Kana huwandu hweinki hwakasiyana, kumhanya kweruzha rwayo kwakasiyanawo. Kana saizi yepepa re piezoelectric remuromo wemuromo yaonekwa, kazhinji kureba kwehupamhi hwepulse yefomu rekutyaira chete ndiko kunogona kuchinjwa kuti pave nenzvimbo yepamusoro yepulse.
Parizvino, kune mamwe ma nozzles ane kudonha kwakanyanya mumusika weUV printer. Nozzle yekutanga ine daro re8 mm yakagadziridzwa kuita waveform yakakwira kuti idhindwe 2 cm. Zvisinei, kune rumwe rutivi, izvi zvichaderedza zvakanyanya kumhanya kwekudhinda. Kune rumwe rutivi, zvikanganiso zvakaita seinki inobhururuka uye mavara anotsvedza zvichaitikawo kakawanda, izvo zvinoda hunyanzvi hwepamusoro hwevagadziri veUV printer.
