UV mwenje we LED seyakajairwa mwenje sosi, musimboti wayo wekurapa unoreva ingi dzeUV mushure me UV irradiation inokonzereswa nephotoinitiator, nekudaro ichigadzira emahara radicals kana ion. Aya emahara radicals kana ion uye pre-polymers kana unsaturated monomers mune kaviri bond cross-linking reaction, kuumbwa kwemonomer genes, aya emonomer genes anotanga kuketanira kuita kuti abudise mapolymer solids kure nemorekuru.
Pane akati wandei akakosha zvinhu zvinopesvedzera UV LED kurapa:
Kurapa zvinhu hunhu
Kukurumidza kupora uye kushanda kweUV LED yekurapa michinakunonyanya kuenderana nekuoma kwechiedza kukonzeresa mamorekuru mumidziyo yekurapa. Kurapa kweUV kunotemerwa nekudhumhana pakati pemafotoni nemamorekuru. Chiedza chinoita kuti mamorekuru apararire zvakafanana kuburikidza nechinhu. Pamusoro pehunhu hwemidziyo yekurapa, iyo optical uye thermodynamic zvimiro zvekurapa zvinhu uye kudyidzana kwavo nesimba rinopenya zvine chekuita kwakakosha pakurapa.
Spectral Absorption Rate
Huwandu hwesimba rechiedza rinotorwa neUV coatings sezvavanowedzera mukukora kunonzi spectral absorption rate. Iyo yakawanda simba rinotorwa pedyo nepamusoro, simba shoma rinochengetwa muzvikamu zvakadzika. Zvisinei, mamiriro ezvinhu aya anosiyana kune zvakasiyana-siyana zvewavelengths. Iyo yakazara spectral absorption rate inosanganisira mhedzisiro yemwenje inokonzeresa, monomolecular zvinhu, oligomers, additives uye pigment.
Kufungisisa uye kuparadzira
Panzvimbo pokunyura, simba rechiedza rinokanganiswa nekushanduka kwegwaro reinki, zvichikonzera kufungisisa uye kupararira. Izvi zvinowanzo konzerwa ne matrix zvinhu kana pigment muzvinhu zvinorapika. Izvi zvinhu zvinodzikisira huwandu hwesimba reUV rinosvika kune dzakadzika maseru, asi kuvandudza kurapa kwakanaka panzvimbo yekuita.
Infrared absorption rate uye yakakodzera UV wavelength
Tembiricha ine mhedzisiro yakakosha pakumhanya kwemaitiro ekurapa, uye tembiricha inokwira panguva yekupindura inoitawo basa. Ingi dzakasiyana dzeUV dzinoda dzakasiyana UV wavelengths yekurapa. Pakusarudza yekurapa unit, zvakakosha kuti usarudze imwe inoenderana newavelength inodiwa neUV coatings. Kushandisa aUV LED yekuporesa unitneiyo wavelength chaiyo ichapa zvirinani kurapa mhedzisiro.
