Goobta daabacaadda, qalinka loo isticmaalo daabacaadda ayaa sidoo kale muujiyay shuruudaha u dhigma, UV khad loogu talagalay daaweynta degdegga ah, ilaalinta deegaanka iyo faa'iidooyinka kale ee warshadaha daabacaadda.Khad daabacaadda UV inta lagu jiro daabacaadda offset-ka, xaraf-xarafeedka, daabacaadda gravure, daabacaadda shaashadda iyo daabacaadda khadka iyo meelaha kale ee daabacaadda, maqaalkani waxa uu la wadaagaa aqoonta khad UV ee la xidhiidha, nuxurka asxaabta tixraaca:

Qeexid

UV: Gaaban ee iftiinka ultraviolet.Ultraviolet (UV) waa mid aan la arki karin isha qaawan.Waa qayb ka mid ah shucaaca korantada ee aan ahayn iftiinka guduudan ee muuqda.Mawjada dhererkeedu waa inta u dhaxaysa 10 ~ 400nm

Khad UV: Khad UV, waxa loola jeedaa khad daweynta degdega ah ee iftiinka UV

Astaamaha

1, Xawaaraha qalajinta waa dhakhso, waqti badbaadi, hoos shucaaca iftiinka UV, u baahan dhowr ilbiriqsi ilaa dhowr ilbiriqsi waa la daweyn karaa.

2, Qalabku wuxuu daboolayaa aag yar yar, hawlgalka socodka daabacaadda, badbaadinta shaqaalaha, faa'iidooyinka dhaqaale.

3, ka badan khad kasta marka laga reebo khad qallajinta uumiga dabiiciga ah, wuxuu badbaadin karaa tamarta.

4, xaalad isku mid ah dhumucda filimka qalalan, kaydinta khad badan.

5, ma xoqin doono, ilaa iyo inta aan la xiriirin shucaaca ultraviolet ma qallajin doono si adag khad.

6, xasilloonida midabka wanaagsan.

7, dhalaal sare.

8, qaybo khad oo yaryar, waxay daabacan karaan qaabab fiican.

9, daabacaadda hawada deegaanka waa cusub, ur yar, ma VOC.

Waxyaabaha ugu muhiimsan

Qaybaha ugu muhiimsan ee khad UV waxaa ka mid ah midabka, oligomer, monomer (diluent firfircoon), sawir-qaade iyo qalabyo kala duwan.Waxaa ka mid ah, resin iyo diluent firfircoon ayaa door ka ciyaara hagaajinta midabka iyo bixinta guryaha sameynta filimada;Pigments waxay siinayaan khad midab dhexdhexaad ah waxayna awood daboolaan substrate-ka;Photoinitiator ayaa looga baahan yahay inuu awood u yeesho inuu nuugo sawir-qaadayaasha hoos yimaada faragelinta midabada si loo bilaabo polymerization.

1, Iskudhisyada monomolecular (diluent reactive)

Tani waa xarun fudud oo leh miisaan yar oo kelli ah, waxay yareyn kartaa viscosity, waxay ciyaari kartaa door kala firdhisan, waxay kala firdhi kartaa midabada, milmi kartaa xabagta, waxay go'aamin kartaa xawaaraha daaweynta iyo ku dhegganaanshaha khad, waxayna ka qaybqaadan kartaa bogsiinta UV resin falcelinta isdhaafsiga.

2, Wax lagu daro

Oo ay ku jiraan midabada, saliidaha, wakiilka dhumucda, buuxinta, wakiilka adkaynaya, iwm. Waxay saamaysaa dhalaalka khad, viscosity, jilicsanaanta, midabka, dhumucda filimka, xawaaraha daaweynta, ku habboonaanta daabacaadda iyo sifooyinka kale.

3, Resin Adag oo Fudud ah waa Shayga Isku Xidha UV

Xawaaraha daweynta khad UV, dhaldhalaalka, adhesion, iska caabinta xoqidda iyo sifooyin kale, khad kala duwan ayaa leh noocyo kala duwan oo resin isku dhafan.

4, Bilow Iftiin

Initiator Light sida buundada u dhaxaysa falcelinta kiimikada, waa nooc ka mid ah excitation iftiinka noqday mid aad u firfircoon, ka dib markii nuugo photons soo saartaa xagjirka lacag la'aan ah, tamar wareejin xagjirka lacag la'aan ah in ay polymer photosensitive kale, soo saaro falcelin silsilad ah, walxaha molecule hal, lagu daro, xabagta adag iftiin iftiin Si wada jir ah u samee falcelinta khad daaweynaysa, ka dib marka la sii daayo tamarta lafteedu kuma lug laha falcelinta isku xidhka.

Mabaadi'da Midaynta

Marka la eego shucaaca iftiinka ultraviolet, nuugista tamarta bilawga iftiinka si ay u soo saarto xagjirnimo bilaash ah, dhaqdhaqaaq bilaash ah oo xawaare sare leh, isku dhacu wuxuu ku dhacaa resin iyo hal unug molecular ah, u wareejinta tamarta resin iyo hal unugyo molecule, resin iyo hal unug hal unug. Ka dib markii la nuugo excitation tamarta ka kooban unsaturated atoms double bond polymerized monomer polymer iyo radicals, kuwaas oo, resin iyo xeryahooda molecule hal, Waxay furaan bond double iyo bilaabaan falcelin cross-linking, a cross-linking, kaas oo photoinitiator lumin tamarta iyo soo laabtay. ilaa heerkiisii ​​asalka ahaa.

Qodobada Saameynaya

Khadka daweynta UV waa inuu lahaadaa iftiinka UV si loo daweeyo, haddii kale lama isticmaali karo.Isticmaalka khad UV, dhibaatada ugu horreysa ee ku dheggan waa in khad UV uusan lahayn daaweyn qoto dheer.Marka la eego qalabka adag ee iftiinka, sababtu waxay noqon kartaa fashilka qalabka daaweynta UV, taas oo ah, dhererka dhererka ee qalabka daaweynta UV uma dhigma khad adag iftiinka UV, ama tamarta adag ee iftiinka ah kuma filna, ama xawaaraha iftiinka iftiinka ku haboon.

1, Iftiin khafiif ah khad adag UV iftiinka kala duwan ee dareenka spectral ee hirarka dhererka u dhexeeya 180-420NM.

2, awooda nalka UV waa in uu buuxiyaa shuruudaha tignoolajiyada ee daaweynta khad.

3, Xawaaraha daabacaadda oo aad u degdega ayaa sidoo kale saameeya xawaaraha daweynta khad.

4, saamaynta dhumucda khad, khad aad u dhumucdiisuna waxay saameyn doontaa saamaynta daaweynta, dhammaan arrimaha saameeya dhumucda filimka daabacaadda waxay saamayn doonaan saamaynta daaweynta

5, saamaynta cimilada: heerkulka sare, viscosity khad UV noqday hooseeyo, ka dib markii la daabacay, fududahay in la soo saaro ifafaale version koollada.Heerkulka hooseeya, viscosity sare, wuxuu saameeyaa thixotropy khad, heerkulka aqoon-is-weydaarsigu ma noqon karo mid aad u sarreeya, xilliga jiilaalka ee bakhaarka qaboojiyaha, waa in lagu dhejiyaa heerkulka qolka, oo ku habboon hoos u dhigista xawaaraha daaweynta.

6, saamaynta midabka ee khad UV: sababtoo ah midabyo kala duwan oo ku saabsan nuugista iftiinka, milicsiga iyo midabka midabka guud ahaan, caddaan, madow, buluug ayaa aad u adag in la daweeyo, casaan, jaalle, saliid iftiin leh, saliid hufan oo si sahlan loo daaweyn karo .
