Gukiza kabiri nubuhanga bushya, bukomatanya ibyiza byo gukiza amashyuza bisanzwe hamwe na sisitemu yo gukiza UV.Irashobora gutanga uburyo bwiza bwo guhangana nubushakashatsi bwimiti ya UV, mugihe igicucu gikiza binyuze mumashanyarazi.Iyi mikorere ituma gukira kabiri guhitamo gushimishije kumodoka imbere.Ihinduka ryibikorwa byayo kandi ryemerera uwasabye guhindura no guhindura umurongo uhari utarinze kubaka guhera.
Nkuko ubusobanuro bwubusobanuro bwijambo "gukiza kabiri" bubigaragaza, ubu buhanga ni ihuriro ryo gukiza UV no gukiza ubushyuheresin.UV acrylate monomer na oligomer, ifoto,acrylic resinna solvent bigize ibice shingiro.Ibindi byahinduwe bisigara ninyongeramusaruro nabyo birashobora gushirwa mumata.Ihuriro ryibi bikoresho fatizo bigize sisitemu ifatanye neza na substrate nyinshi, mugihe itanga ubukana bwubuso butagira inenge, kwihanganira gushushanya no kwambara.
Isuzuma rya matrix yo gukiza kabiri muri rusange igabanijwemo ibyiciro bine: gufatira hamwe, kurwanya ibishushanyo, kurwanya imiti no kurwanya ikirere.Ubushuhe bukiza ubushyuhe burashobora kugira "kwikiza" biranga, kandi gukuramo hejuru no gushushanya amaherezo bizashira kubera guhinduka kwa resin.Nubwo iki ari ikintu cyiza uhereye kubitekerezo, nanone bituma igifuniko kibangamiwe n’imiti itandukanye.Ububiko bwa UV mubusanzwe bufite urwego rwo hejuru rwumusaraba uhuza ubuso, byerekana gukomera gukomeye, ariko igifuniko kiroroshye kandi cyoroshye kubyara ibibazo hamwe nikirere.
Hano haribisabwa bibiri gusa byo gutunganya ibyokurya bibiri byo gukiza: ifuru yo gukiza amashyuza n itara rya ultraviolet yo gukiza acrylate.Ibi bifasha coater guhindura umurongo uhari wo gukora amarangi utubatse umurongo mushya wo gukora amarangi.
Imwe mu mbogamizi nini zuburyo bubiri bwo gukiza ni ukugabanya kuvanga amabara.Sisitemu nyinshi zo gukiza UV ziragaragara cyangwa zifite ibara ryoroshye, kuko ibara rizabangamira gukira UV.Pigment, ifu ya puwaro hamwe nicyuma gishobora kubuza gukira ukwirakwiza imirasire ya ultraviolet no kubuza imirasire ihagije ya ultraviolet kwinjira mubitambaro (Ishusho 3).Igisubizo nugukora acrylate idakize hafi yimbere ya substrate.Iyo hejuru yo gukusanya ibifuniko byamabara, niko gukira gukabije.
