Nibihe bintu bigize UV ​​ishobora gukira?

UV gukiza (UV) ni ubwoko bushya bwo gutwikira ibidukikije.Igipimo cyacyo cyihuta cyane.Irashobora gukizwa numucyo UV mumasegonda make, kandi umusaruro urakabije.

UV ikiza coating igizwe ahanini na oligomers, diluents ikora, fotinitiator ninyongera.

1. Oligomer

Ibikoresho byo gukora firime nigice cyingenzi cyo gutwikira, aricyo kintu cyamazi yo gutwikira.Imikorere ya firime, imikorere yubwubatsi nibindi bintu byihariye byo gutwikira biterwa ahanini nibikoresho bikora firime.Ibikoresho byerekana firime ya UV itwikiriye ni oligomer, kandi imikorere yayo ahanini igena imikorere yubwubatsi nigipimo cyo gukiza cyumucyo mbere yo gukira, imikorere ya firime nyuma yo gukira nibindi bintu bidasanzwe.

UV itwikiriye cyane cyane sisitemu yo gukiza yumucyo yubusa, so oligomers ikoreshwa nubwoko bwose bwa acrylic resin.Cationic UV itwikiriye oligomers ni epoxy resin hamwe na vinyl ether.

2.Ibikorwa byiza

Gukora neza ni ikindi kintu cyingenzi kigize UV.Irashobora kugabanya no kugabanya ubukonje, kandi ikagira n'umutungo wo guhindura firime ikiza.Acrylate ikora monomers ifite reaction nyinshi kandi ihindagurika cyane, kuburyo ikoreshwa cyane muri UV.Acrylic esters isanzwe ikoreshwa nkibikoresho bikora kuri UV.Muri formulaire nyayo, mono -, ikora kandi ikora cyane ya acrylates izakoreshwa hamwe kugirango imitungo yabo yuzuzanye kandi igere ku ntego yingaruka nziza.

3. Ifoto

Photoinitiator ni umusemburo udasanzwe muri UV.Nibintu byingenzi bigize ibishishwa bya UV kandi bigena igipimo cya UV cyo gukira cya UV.

Kubirangi bitagira ibara bya UV, 1173, 184, 651 na bp / kaminuza ya amine bikunze gukoreshwa nkifoto.184 hamwe nibikorwa byinshi, impumuro nke hamwe no kurwanya umuhondo, niyo fotoinitiator ikunzwe kumuhondo UV irwanya umuhondo.Kugirango tunoze igipimo cyo gukiza urumuri, gikoreshwa kenshi hamwe na TPO.

Kubara amabara ya UV, amafoto yerekana amafoto agomba kuba itx, 907, 369, TPO, 819, nibindi. Rimwe na rimwe, kugirango ugabanye okisijene polymerisiyasi no kunoza igipimo cyo gukira UV, umubare muto wa amine udakunze kwongerwaho muri UV.

4. Inyongera

Inyongeramusaruro nibikoresho byingirakamaro bya UV.Uruhare rwinyongera nugutezimbere imikorere yo gutunganya, imikorere yububiko hamwe nubwubatsi bwububiko, kunoza imikorere ya firime no guha firime ibikorwa byihariye.Ibisanzwe bikoreshwa mubyongewemo UV birimo defoamer, agent iringaniza, ikwirakwiza amazi, poroteri ya adhesion, agent ya matting, inhibitor ya polymerisation, nibindi, bigira uruhare rutandukanye muburyo bwa UV.
