I-LED UV Curing Systems yemishini yokunyathelisa: yini okufanele uyiqhathanise

Ukuthola izinhlelo ezifanele zokuphulukisa i-UV ze-LED zokuphrinta ukuthuthukiswa komshini kungazizwa njengokuzulazula i-maze yama-specs obuchwepheshe nezithembiso zomkhiqizi. Uma usebenzisa i-offset noma i-flexo press, uyazi ukuthi ukukhetha okungalungile akugcini nje ngokubiza imali—kubiza isikhathi sokuphumula, i-substrate elahlekile, namakhasimende alahlekile.

Ngibonile abaphathi begumbi lokushicilela belwa nezixazululo "zokudonsa" ezingazange zibheke ukuzwela kwabo okuthile, ukushisa noma isivinini somugqa. Iqiniso liwukuthi akuwona wonke ama-LED arrays adalwe ngokulinganayo. Ukuze uthole isikhathi sokuphila kwamahora angama-20,000 + nokusebenza kahle okusheshayo okuthembisayo kwe-LED, udinga ukubheka ngale kwe-wattage yencwajana. Udinga ukuqhathanisa izici "ezingabonakali": ukwakhiwa kokupholisa, ukulawulwa kwe-optical, kanye ne-logic yokuhlanganisa.

Lo mhlahlandlela uphula kahle ukuthi yini okufanele uyiqhathanise ukuze ukwazi ukukhetha uhlelo oluletha ukwelashwa okungaguquguquki, ukushintsha ngemuva kokushintsha.

Yimaphi amamethrikhi okusebenza abalulekile we-LED UV curing?

Ukuhlola ukusebenza, bheka ngaphesheya kwe-peak irradiance (W / cm²). Kufanele uqhathanise ukuminyana kwamandla aphelele (J / cm²) alethwe ku-substrate ngesivinini sakho esiphezulu somugqa. Ukuqina okuphezulu kwe-peak akusizi ngalutho uma isikhathi sokuhlala sifushane kakhulu ukuthi singafaka i-polymerize ngokugcwele inki. Njalo cela idatha ngokufana komthamo kuwo wonke ububanzi bokwelapha.

Deep Dive: Irradiance vs. Energy Density

Uma uqhathanisa ama-specs, abakhiqizi abaningi bamemeza nge-Peak Irradiance yabo—bavame ukucaphuna izinombolo ezinjenge-12W / cm² noma i-16W / cm². Ngenkathi ukuqina okuphezulu kuyadingeka ukungena ezingqimbeni zeyinki ezijiyile (ikakhulukazi abamhlophe noma abamnyama), akuyona yonke indaba.

Ukuze uqhathanise ngokuphelele, udinga ukugxila ku-Energy Density (kulinganiswa ku-Joules / cm²). Leli yinani eliphelele lamandla e-UV afika endaweni yakho yokuphrinta ngokuhamba kwesikhathi.

• I-Peak Irradiance: "Isibhakela" sokukhanya (ukuqina).
• Ukuminyana kwamandla: "Isibhakela" siphindaphindwe ngesikhathi sishaya inki (umthamo).

Uma usebenzisa umshini wokucindezela wewebhu osheshayo, uhlelo olunewindi elincane lokukhipha kungenzeka lungalethi amandla anele okuphelele ukwelapha inki, noma ngabe ukuqina kwayo okuphezulu kuphezulu. Udinga uhlelo olunewindi elibanzi lokukhipha noma ama-optics asebenza kahle kakhulu ukugcina ikhwalithi yokwelapha ngesivinini.
