Dulmar guud oo ku saabsan Waxyaalaha Saameeya UV LED Curing

Nalalka UV LED sida isha iftiinka caadiga ah, mabda'a daaweynta waxay tilmaamaysaa khadadka UV ka dib markii shucaaca UV uu kiciyo sawir-qaade, sidaas darteed soo saarida xagjirnimo bilaash ah ama ion. Xagjirayaashan xorta ah ama ion iyo pre-polymers ama monomers-ka unsaturated ee falcelinta isku-xidhka isku-xidhka labalaabka ah, samaynta hiddo-wadaha monomer-ka, hidde-sidayaashan monomer waxay bilaabaan falcelinta silsiladda si ay u dhaliyaan adkaha polymer ka fog molecule-ka.

Waxaa jira dhowr arrimood oo muhiim ah oo saameeya daaweynta UV LED:

Daawaynta sifooyinka alaabta

Xawaaraha daawaynta iyo waxtarkaQalabka daaweynta UV LEDwaxay inta badan ku xiran tahay dhibka iftiinka si uu u kiciyo molecules-ka ku jira alaabta daaweynta. Dawaynta UV waxaa lagu go'aamiyaa isku dhaca photons iyo molecules. Iftiinku wuxuu keenaa in unugyadu ay si isku mid ah ugu faafsadaan walxaha. Marka lagu daro sifooyinka qalabka daawaynta, sifooyinka indhaha iyo heerkulbeegga ee qalabka daaweynta iyo isdhexgalka tamarta iftiinka ayaa saameyn weyn ku leh habka daaweynta.

Heerka nuugista Spectral

Qadarka tamarta iftiinka ee ay nuugaan dahaarka UV marka ay kordhiyaan dhumucda ayaa loo yaqaan heerka nuugista spectral. Tamar badan oo la nuugo meel u dhow dusha sare, tamarta yar ayaa lagu hayaa lakabyada qoto dheer. Si kastaba ha ahaatee, xaaladdan waxay ku kala duwan tahay hirarka hirarka kala duwan. Wadarta heerka nuugista spectral waxaa ka mid ah saamaynta kiciyeyaasha iftiinka, walxaha monomolecular, oligomers, daroogooyinka iyo midabada.

Milicsiga iyo kala firdhiso

Halkii la nuugi lahaa, tamarta iftiinka waxaa saameeya isbeddelka jihada khadku, taasoo keentay milicsi iyo kala firdhis. Tan guud ahaan waxaa sababa maadooyinka tusmada ama midabada ku jira walxaha la daweyn karo. Arrimahani waxay yareeyaan xaddiga tamarta UV ee gaadhaysa lakabyada qoto dheer, laakiin waxay hagaajiyaan waxtarka daaweynta ee goobta falcelinta.

Heerka nuugista infrared iyo hirarka UV ee habboon

Heerkulka ayaa saameyn weyn ku leh xawaaraha falcelinta daweynta, iyo kor u kaca heerkulka inta lagu jiro falcelinta ayaa sidoo kale door ka ciyaara. Khadadka kala duwan ee UV waxay u baahan yihiin mawjadaha dhererka UV ee kala duwan si loo daaweeyo. Marka la dooranayo unugga daweynta, waxaa muhiim ah in la doorto mid u dhigma dhererka hirarka loo baahan yahay dahaarka UV. Isticmaalka aCutubka daaweynta UV LEDMawjadaha saxda ah ee dhererka saxda ah waxay ku siin doontaa natiijooyin daaweyn wanaagsan.
