The Core Mechanism: Photopolymerization Explained

Enhliziyweni yazo zonke izinhlelo ze-inkjet ze-UV zezimboni ukusabela kwamakhemikhali, hhayi inqubo yokomisa. Ama-inki wendabuko asuselwa emanzini noma ama-solvent ome lapho isithwali samanzi sihwamuka emoyeni. Kodwa-ke, ama-inks e-UV aphenduka kusuka kuketshezi kuya kokuqinile ngokuxhumanisa isiphambano.

Inqubo incike ezingxenyeni ezintathu eziyinhloko ngaphakathi kwe-inki:

1. I-Photoinitiators: "i-trigger" ephendula ekukhanyeni kwe-UV.
2. Ama-Monomers nama-Oligomers: "Amabhlogo okwakha" epulasitiki.
3. I-Pigments: Imibala.

Cabanga ngalokhu njengendlela ethi "Lock and Key". Ukukhanya kwe-UV LED kusebenza njengesihluthulelo. Lapho ishaya i-photoinitiator (ilokhi), i-initiator iyaqhekeka futhi idale ama-radicals wamahhala. Lawa ma-radicals aqala ukusabela kweketanga, aphoqa ama-monomers awuketshezi ukuthi ahlanganise ndawonye ngokushesha abe yinethiwekhi ye-polymer eqinile, exhunywe esiphambanweni.
