UV yekurapa tekinoroji yakashandura indasitiri yekudhinda, ichipa kukurumidza kurapa nguva, kuwedzera chigadzirwa uye kuderedzwa kwesimba rekushandisa. Nekudaro, kuvepo kweokisijeni panguva yekurapa kunogona kuve nemhedzisiro yakakura pakuita kweUV kurapwa kweingi.
Oxygen inhibition inoitika kana mamorekuru eokisijeni achikanganisa mahara radical polymerization, zvichikonzera kusakwana kwekurapa uye kukanganisa inki kuita. Ichi chiitiko chinonyanya kutaurwa mune ingi dzakatetepa uye dzine nzvimbo yakakwirira kusvika kuhuwandu hwehuwandu.
Kana UV inorapika ingi ichiiswa kumhepo yakadzikama, mamorekuru eokisijeni akanyungudika mukugadzira inki uye okisijeni yakaparadzaniswa kubva kumhepo inogona kukanganisa maitiro epolymerization. Iyo yakaderera kusanganiswa kweokisijeni yakanyungudika inopedzwa zviri nyore neyekutanga reactive mahara radicals, zvichikonzera iyo polymerization induction nguva. Kune rumwe rutivi, okisijeni inogara ichipararira muinki kubva kune imwe nzvimbo yekunze inova chikonzero chikuru chekudzivisa.
Mhedzisiro yekudzivirira kweokisijeni inogona kusanganisira nguva refu yekurapa, kunamatira kwepamusoro uye kuumbwa kweiyo oxidized zvimiro pane inki pamusoro. Izvi zvinogona kuderedza kuoma, kupenya uye kukwenya kuramba kweinki yakarapwa uye kukanganisa kugadzikana kwayo kwenguva refu.
Kukunda matambudziko aya, vaongorori uyeUV LED vagadzirivakaongorora nzira dzakasiyana-siyana.
Yokutanga ndeyekuchinja maitiro ekuita. Nekuvandudza iyo photoinitiator system, pamusoro peokisijeni inhibition yeiki yakarapwa inogona kudzvinyirirwa.
Kuwedzera kuwanda kwemafotoinitiators ndiyo imwe nzira yekudzikisa mhedzisiro yeokisijeni inhibition. Nekuwedzera mamwe mafotoinitiators, iyo inki yekugadzira inova yakanyanya kupesana neokisijeni inhibition. Izvi zvinoguma nekuoma kweinki yepamusoro, kunamira kuri nani uye kupenya kwepamusoro mushure mekurapa.
Uye zvakare, kuwedzera kusimba kweiyo UV yekurapa michina mumidziyo yekurapa kunobatsira kudzikisira mhedzisiro yakaipa yeokisijeni inhibition. Nekuwedzera simba reiyo UV mwenje sosi, nzira yekurapa inova inoshanda zvakanyanya uye inotsiva iyo yakaderedzwa reactivity inokonzerwa nekukanganiswa kweokisijeni. Iyi nhanho inofanirwa kunyatsogadziriswa kuti ive nechokwadi chekurapa kwakaringana pasina kukuvadza substrate kana kukonzera mimwe mhedzisiro yakaipa.
Chekupedzisira, inhibition yeokisijeni inogona kudzikiswa nekuwedzera imwe kana anopfuura okisijeni scavenger kumidziyo yekudhinda. Aya ma scavengers anopindura neokisijeni kuti aderedze kusungirirwa kwayo, uye musanganiswa weiyo yakanyanya kusimbaLED UV yekurapa systemuye iyo oxygen scavenger inogona kuderedza kukanganiswa kweokisijeni pakugadzirisa nzira.Nezvigadziriso izvi, vagadziri vanogona kuwana zviri nani kuporesa kushanda uye kukunda matambudziko ekudzivisa oksijeni.
