Ose ari maviri UV (ultraviolet) uye EB (electron beam) kurapa anoshandisa electromagnetic mwaranzi, iyo yakasiyana neIR (infrared) kupisa kupisa. Kunyangwe UV (Ultra Violet) neEB (Electron Beam) aine masaisai akasiyana-siyana, ese ari maviri anogona kukonzeresa kusanganiswa kwekemikari muinki sensitizer, kureva, high-molecular crosslinking, zvichikonzera kuporeswa ipapo.
Kusiyana neizvi, IR kurapa inoshanda nekudziya iyo inki, ichigadzira akawanda mhedzisiro:
● Kufefeterwa kwechinhu chidiki chesolvent kana unyoro,
● Kupfava kweiyo inki layer uye kuwedzera kuyerera, kunobvumira kunyura uye kuomesa,
● Surface oxidation inokonzerwa nekudziya uye kubata nemhepo,
● Kuporeswa kwekemikari kwechidimbu kweresin nemafuta epamusoro-molecular pasi pekupisa.
Izvi zvinoita kuti IR irape maitiro akawanda-akawanda uye chidimbu chekuomesa, pane imwechete, yakakwana yekurapa maitiro. Solvent-based inki dzinosiyana zvakare, sezvo kurapa kwavo kuri 100% kunowanikwa nekunyungudika kwesolvent ichibatsirwa nekuyerera kwemhepo.
Musiyano Pakati peUV uye EB Kurapa
Kurapa kweUV kunosiyana neEB kurapa kunyanya mukudzika kwekupinda. UV mwaranzi ine zvishoma kupinda; semuenzaniso, 4–5 µm mukobvu inki layer inoda kunonoka kurapwa ine high-energy UV mwenje. Haikwanise kurapwa nekumhanya kwakanyanya, senge mapepa 12,000–15,000 paawa mukudhinda kweoffset. Zvikasadaro, iyo yepamusoro inogona kurapa nepo mukati memukati ichiramba iri mvura-sezai risina kubikwa-zvichigona kuita kuti pasi rinyunguduke zvakare uye kunamatira.
Kupinda kweUV zvakare kunosiyana zvakanyanya zvichienderana neingi ruvara. Ingi dzeMagenta neCyan dzinopinzwa zviri nyore, asi ingi dzeYero neDema dzinotora yakawanda yeUV, uye Ingi Ichena inoratidza yakawanda UV. Naizvozvo, kurongeka kwemavara ekuisa mukudhinda kunobata zvakanyanya kurapa kweUV. Kana ingi dzeDema kana Yeroti dzine yakakwira UV kunyura dziri pamusoro, iyo iri pasi peRed kana Blue ingi inogona kurapa zvisina kukwana. Sezvineiwo, kuisa ingi Dzvuku kana yeBlue kumusoro uye Yero kana Dema pasi kunowedzera mukana wekupora zvachose. Zvikasadaro, rumwe rutivi rwemavara runogona kuda kupora kwakasiyana.
EB kurapa, kune rumwe rutivi, haina misiyano inoenderana neruvara mukurapa uye ine kupinda kwakasimba zvakanyanya. Inogona kupinda mubepa, mapurasitiki, uye mamwe ma substrates, uye kunyange kurapa mativi ese ekudhindwa panguva imwe chete.
Kufunga Kwakakosha
Ingi dzakacheneruka dzepasi dzakanyanya kunetsa pakurapa UV nekuti dzinoratidza UV mwenje, asi EB kurapa haina kukanganiswa neizvi. Iyi ndiyo imwe mukana weEB pamusoro peUV.
Nekudaro, kurapa kweEB kunoda kuti nzvimbo yacho ive munzvimbo isina okisijeni kuti iwane kukwana kwakakwana kwekurapa. Kusiyana neUV, iyo inogona kurapa mumhepo, EB inofanirwa kuwedzera simba kupfuura kagumi mumhepo kuti iwane mibairo yakafanana-kuvhiya kwakaipisisa kunoda kuchengetedzwa kwakasimba. Mhinduro inoshanda ndeyekuzadza kamuri yekurapa nenitrogen kubvisa okisijeni uye kuderedza kupindira, zvichibvumira kurapa kwakanyanya.
Muchokwadi, mune semiconductor maindasitiri, UV imaging uye kuratidzwa kunowanzoitwa mu nitrogen-yakazadzwa, isina okisijeni makamuri nekuda kwechikonzero chimwe chete.
EB kurapa saka kwakakodzera chete mapepa akatetepa mapepa kana epurasitiki mafirimu mukuputira uye kudhinda maapplication. Haikodzeri mashizha-akadyiswa mashizha ane mechanical cheni uye grippers. Kurapa kweUV, mukusiyana, kunogona kushandirwa mumhepo uye kunonyanya kushanda, kunyangwe okisijeni-isina UV kurapa isingawanzo kushandiswa mukudhinda kana kuvhara maapplication nhasi.
