Kakaretso ea Lintlha tse Amang Pheko ea LED ea UV

Lebone la UV LED e le mohloli o tloaelehileng oa leseli, molao-motheo oa eona oa pholiso o bua ka li-inks tsa UV ka mor'a hore mahlaseli a UV a hlahisoe ke photoinitiator, kahoo a hlahisa li-radicals tsa mahala kapa li-ion.Li-radicals tsena tsa mahala kapa li-ion le li-pre-polymers kapa li-unsaturated monomers ka bobeli bond cross-linking reaction, sebopeho sa liphatsa tsa lefutso tsa monoma, liphatsa tsa lefutso tsa monoma li qala ho etsa ketane ho hlahisa lintho tse tiileng tsa polymer hole le molek'hule.

Ho na le lintlha tse 'maloa tsa bohlokoa tse susumetsang pholiso ea UV LED:

Litšobotsi tsa ho folisa

Lebelo la ho phekola le katleho eaLisebelisoa tsa ho folisa tsa LED tsa UVe itšetlehile haholo ka bothata ba leseli ho hlahisa limolek'hule linthong tse phekolang.Pholiso ea UV e khethoa ke ho thulana pakeng tsa photon le limolek'hule.Leseli le etsa hore limolek'hule li hasane ka mokhoa o ts'oanang ka thepa.Ntle le litšoaneleho tsa lisebelisoa tsa ho folisa, lisebelisoa tsa optical le thermodynamic tsa lisebelisoa tsa ho folisa le ho sebelisana ha tsona le matla a khanyang li na le phello e kholo ts'ebetsong ea ho folisa.

Sekhahla sa ho monya ha Spectral

Boholo ba matla a khanya a monngoang ke lirafshoa tsa UV ha li ntse li eketseha botenya bo bitsoa sekhahla sa spectral absorption.Ha matla a mangata a kenngoa haufi le bokaholimo, matla a fokolang a bolokoa likarolong tse tebileng.Leha ho le joalo, boemo bona bo fapana bakeng sa maqhubu a fapaneng.Kakaretso ea sekhahla sa ho monya ha spectral e kenyelletsa litlamorao tsa lintho tse hlahisang leseli, lintho tse monomolecular, li-oligomers, li-additives le li-pigments.

Boikutlo le ho hasanya

Ho e-na le ho monya, matla a khanya a angoa ke ho fetoha ha tsela ea enke, ho fella ka ho bonahatsa le ho hasana.Hangata sena se bakoa ke lisebelisoa tsa matrix kapa li-pigments tse ka har'a thepa e phekolehang.Lintlha tsena li fokotsa bongata ba matla a UV a fihlang makaleng a tebileng, empa a ntlafatsa ts'ebetso ea ho folisa sebakeng sa karabelo.

Sekhahla sa ho monya ha infrared le leqhubu le loketseng la UV

Mocheso o na le phello e kholo lebelong la ho folisa, 'me ho phahama ha mocheso nakong ea karabelo le hona ho phetha karolo.Li-ink tse fapaneng tsa UV li hloka maqhubu a fapaneng a UV ho folisa.Ha u khetha yuniti ea ho folisa, ho bohlokoa ho khetha e lumellanang le bolelele ba maqhubu bo hlokoang ke masela a UV.Ho sebelisa aSetsi sa pholiso sa UV LEDka wavelength e nepahetseng e tla fana ka liphello tse molemo tsa phekolo.
