Ukwakhiwa kweyinki ye-UV offset
2024-05-13
Oyinki bokuphrinta be-UV offset bayizinto zokuphrinta ezikhethekile eziklanyelwe ukwelapha ukukhanya kwe-ultraviolet (UV) okusheshayo. Ukwakheka kwazo kuklanywe ngokucophelela ukuze kuqinisekiswe ikhwalithi yokuphrinta ephezulu kanye nezakhiwo zokomisa ngokushesha. Izingxenye ezibalulekile zalawa ma-inki zingachazwa kanje:
- Izinsalela Ezelaphekayo yi-UV: Enhliziyweni yalawa ma-inki kukhona ama-resin angezwani ne-UV, njengama-acrylates, i-ethylene esters, nama-epoxy resins, axhumanisa ngokushesha futhi elapha ngaphansi kwemisebe ye-UV.
- Ama-monomers: Asetshenziswa ngokuhambisana nama-resin elapheka e-UV, ama-monomers afana ne-acrylic ne-methacrylic acid ester enza kube lula izinqubo ze-polymerization lapho kwenziwa kusebenze ukukhanya kwe-UV, kusheshisa inqubo yokwelapha.
- Ama-Photoinitiators: Lezi zinhlanganisela zimunca amandla e-UV futhi ziwaguqule abe amandla amakhemikhali, acuphe ukusabela kwe-polymerization ngaphakathi kweyinki. Bahlanganisa abaqalisi bokuqala kanye nama-axiliary agents.
- Ama-Pigment and Pigment Dispersants: Ama-Pigment ahlinzeka ngombala nomthelela obonakalayo, kuyilapho ama-disperants aqinisekisa ngisho nokusakazwa kwemibala yemibala engashintshi kanye nekhwalithi yokuphrinta.
- Izithasiselo: Kubandakanya ama-antioxidants, ama-UV stabilizers, ama-rheology modifiers, ama-hardeners, phakathi kokunye, lezi zifakiwe ukuthuthukisa ukusebenza kwe-inki nokuzinza. Ama-Diluents nawo asetshenziselwa ukulungisa i-viscosity nokugeleza, ukuhlinzeka ngezidingo ezihlukahlukene zokuphrinta.
- Izithako Ezengeziwe: Ngokuya ngomkhiqizi kanye nezidingo ezithile zohlelo lokusebenza, oyinki bangahlanganisa izinto ezengeziwe njengama-ejenti akhululayo kanye nama-anti-settleling agents. Amafomula ayavumelana nezimo ukuze ahlangabezane nemibandela ethile yokusebenza.
Kafushane, oyinki bokuphrinta be-UV offset, ngokuphulukiswa kwabo ngokushesha, ukumelana nemihuzuko, ukumelana namakhemikhali, kanye nekhwalithi yokuphrinta ehlukile, bathola ukusetshenziswa okubanzi embonini yokunyathelisa, ikakhulukazi emisebenzini yokunyathelisa yekhwalithi ephezulu kanye nesezingeni eliphezulu.
