Handheld UV yekurapa marambi zvishandiso zvinoshandisa ultraviolet (UV) mwaranzi kukonzeresa kuita kwemakemikari, nekukurumidza kurapa machira, zvinonamira, kana ingi. Yavo musimboti wekushanda musimboti ndeye photochemical reaction: UV radiation yeawavelength chaiyo inonakidza photoinitiator, iyo inozoita kuti monomers kana oligomers mune izvo zvinhu kuti polymerize kana crosslink, pakupedzisira ichigadzira yakasimba yekupfeka.
Midziyo iyi inowanzo shandisa mercury vapor marambi kana LED mwenje masosi, ine mercury vapor marambi ari kushandiswa zvakanyanya nekuda kwekukwira kwazvo kweUV kubuda. Kana yazvino ikapfuura nemumhute wemercury mukati memwenje, maatomu emercury anonakidzwa kusvika pakakwirira-simba resimba. Ivo vanobva vachinja vachidzokera kupasi uye vanoburitsa UV mwaranzi ine wavelengths yakatarisana ne365nm (UVA), 385nm, kana 405nm. Aya maUV wavelengths anonyatso shandisa photoinitiators (senge benzophenone kana benzoin ether), zvichiita kuti aore uye abudise mahara radicals kana cations, izvo zvinozoita kuti polymerization yeresin zvinhu.
Handheld UV mwenje mwenje wakagadzirirwa kutakurika uye kunyatso kudzora, kazhinji ine inogadziriswa magetsi kubuda uye kuratidzwa nguva kuti ienderane nekurapa zvinodiwa zvezvinhu zvakasiyana. Semuyenzaniso, yakaderera-kusimba modhi yakakodzera mabhachi matete, ukuwo yakakwirira-yakasimba modhi ichishandiswa kurapa nekukasira ma layers. Pamusoro pazvo, marambi emazuva ano e LED UV yekuchenesa mwenje ari kuwedzera kutsiva marambi echinyakare mecury nekuda kwekushomeka kwawo kwesimba, kurarama kwenguva refu, uye mecury{4}mahara kushanda. Nekudaro, yavo yakatetepa wavelength renji inoda chaiyo photoinitiator masisitimu.
Munguva yekushanda kwekushandisa, mushandisi anofanira kuona kuti UV mwenje unovhenekera kumusoro kuti uporeswe kudzivirira mimvuri kana kubuda kwechiedza kunogona kutungamira mukurapwa kusina kukwana. Uyezve, nekuti mwenje weUV unokuvadza paganda remunhu nemaziso, zvishandiso zvinowanzobatanidza nzira dzekuchengetedza dzakadai seyenguva maalarm kana mafirita emeso.
Muchidimbu, marambi ekurapa eUV anobatwa nemaoko, nekunyatso kudzora mwaranzi yeUV uye zvinhu zvekurapa zvine hunyanzvi, anoshandiswa zvakanyanya mumashandisirwo akadai sekusangana kwemagetsi, kudzoreredza mazino, uye maindasitiri ekupfeka. Kuenderera mberi kwetekinoroji kuenderera mberi kuri kufambisa budiriro yekukurumidza kugadzira nekugadzirisa.
