'Dual Cure' smoothens chinja kuUV LED

Anenge makore gumi mushure mekusuma kwavo, UV LED inorapika ingi dziri kutorwa nekukurumidza nekumhanyisa nemalabel converters. Mabhenefiti einki pamusoro pe 'zvakajairwa' mercury UV ingi - zvirinani uye nekukurumidza kurapa, kuvandudzwa kwekusimba uye kuderera kwemitengo yekumhanya - iri kunzwisiswa zvakanyanya. Pamusoro pezvo, tekinoroji iri kusvikika nyore nyore sezvo vagadziri vepanhau vanopa kusanganisa huwandu hwakawanda hwemarambi ehupenyu hurefu pamitsara yavo.
Uyezve, pane kukurudzira kukuru kune vashanduri kuti vafunge kuchinja ku LED, nokuti njodzi uye mari yekuita izvi iri kuderera. Izvi zviri kufambiswa nekuuya kwechizvarwa chitsva che 'mbiri mbiri yekurapa' ingi uye machira anogona kumhanyisa pasi peese maLED nemarambi emercury, achibvumira vashanduri kuti vatore tekinoroji mumatanho, pane kungoerekana.
Musiyano mukuru pakati peyakajairwa mercury rambi uye mwenje we LED ndiwo wavelengths inoburitswa kuti kurapa kuitike. Rambi remercury-vapor rinovheneka simba pakati pe220 ne400 nanometers (nm), ukuwo marambi eLED ane hutete hwewavelength pakati pe375nm ne410nm uye achikwira pamusoro pe395nm.
UV LED ingi dzinorapwa nenzira imwechete seyakajairwa UV ingi, asi inonzwa kune yakatetepa yavelength yechiedza. Vanosiyana kubva kune mumwe nemumwe, saka, neboka remafotoinitiators rinoshandiswa kutanga maitiro ekurapa; iyo pigment, oligomers uye monomers anoshandiswa akafanana.
UV LED kurapa inopa yakasimba kwezvakatipoteredza, mhando, uye chengetedzo zvakanakira pane zvakajairwa kurapwa. Iyo nzira haishandisi mercury kana ozone, saka hapana dhizaini inodiwa kuti ibvise ozone kubva kutenderedza muchina wekudhinda.
Inopa kushanda kwenguva refu zvakare. Mwenje we LED unogona kuvhurwa nekudzimwa pasina chikonzero chekudziya-kumusoro kana kutonhora-pasi nguva, ichipa kushanda kwakanaka kubva panguva yainobatidzwa. Iko hakuna kudikanwa kwezvivharo kuchengetedza substrate kana mwenje wakadzimwa.
