MaOligomers mamorekuru ane mashoma anodzokorora mayunitsi, uye ndiwo makuru ezvikamu zveUV inorapika ingi. UV inorapika ingi ingi dzinogona kuomeswa nekuporeswa nekukasira nekuvhenekwa neultraviolet (UV) mwenje, izvo zvinoita kuti ive yakanakira kudhinda nekumhanyisa maitiro ekuputira. Oligomers anoita basa rakakosha mukuona zvivakwa uye kuita kweUV inorapika ingi, senge viscosity, adhesion, kuchinjika, kusimba, uye ruvara.
Kune matatu makirasi makuru e UV anorapika oligomers, anoti epoxy acrylates, polyester acrylates, uye urethane acrylates. Kirasi yega yega ine maitiro ayo uye mashandisirwo, zvichienderana nerudzi rwe substrate, nzira yekurapa, uye inodiwa mhando yechigadzirwa chekupedzisira.
Epoxy acrylates maoligomers ane mapoka epoxy mumusana wavo, uye acrylate mapoka pamagumo avo. Ivo vanozivikanwa nepamusoro reactivity yavo, yakaderera viscosity, uye yakanaka makemikari kuramba. Nekudaro, ivo vanewo zvimwe zvipingamupinyi, sekusagadzikana kuchinjika, kuderera kunamatira, uye kutsvuka. Epoxy acrylates akakodzera kudhindwa pane dzakaomarara substrates, senge simbi, girazi, uye plastiki, uye kune maapplication anoda yakakwira gloss uye kuoma.
Polyester acrylates maoligomers ane mapoka epolyester mumusana wavo, uye mapoka acrylate pamagumo avo. Ivo vanozivikanwa nekuita kwavo zvine mwero reactivity, yakaderera shrinkage, uye yakanaka kuchinjika. Nekudaro, ivo zvakare vane zvimwe zvipingamupinyi, senge yakakwira viscosity, kushomeka kwemakemikari kuramba, uye kunhuwa kuburitsa. Polyester acrylates akakodzera kudhindwa pane anochinjika substrates, senge bepa, firimu, uye machira, uye kune maapplication anoda kunaka kunamatira uye elasticity.
Urethane acrylates maoligomers ane urethane mapoka mumusana wavo, uye acrylate mapoka kumagumo awo. Ivo vanozivikanwa nekuderera kwavo reactivity, yakakwirira viscosity, uye yakanakisa kuchinjika. Nekudaro, ivo zvakare vane zvimwe zvipingamupinyi, senge mutengo wakakwira, yakakwira oksijeni inhibition, uye yakaderera kurapa kukurumidza. Urethane acrylates akakodzera kudhinda pane akasiyana substrates, sehuni, dehwe, uye rabha, uye kune maapplication anoda kusimba kwepamusoro uye abrasion kuramba.
Mukupedzisa, maoligomers akakosha pakugadzira uye kuita kweUV inorapika ingi, uye inogona kuiswa mumakirasi matatu makuru, anoti epoxy acrylates, polyester acrylates, uye urethane acrylates. Kirasi yega yega ine zvayakanakira nezvayakaipira, zvichienderana nekushandiswa uye substrate. Kuvandudzwa kwemaoligomers uye UV inki inzira inoenderera mberi, uye mhando nyowani dzemaoligomers uye nzira dzekurapa dziri kuongororwa kuti dzisangane nekuwedzera kuri kuda kweindasitiri yeinki.
