Kuyini ukwelashwa kwe-LED UV? Umhlahlandlela ophelele ngezinzuzo, inqubo nokusetshenziswa

Ukubuka konke okufushane kwe-LED Curing Technology 

• Izimboni zanamuhla zokukhiqiza, ukuphrinta, kanye ne-elekthronikhi seziqalile ukusebenzisa izinhlelo zokuphulukisa ze-UV ze-LED. Njengoba ubuchwepheshe obuthuthukisiwe bokujikeleza obuhlanganisiwe buthatha indawo, izinhlelo zabo zokomisa, ukwenza izinto ezilukhuni, noma ukwenza imisebenzi ziyathuthukiswa. Kuyini ukwelashwa kwe-LED UV? Kungani ubuchwepheshe be-LED UV buthandwa kakhulu kunezindlela zendabuko zokuphulukisa, futhi basebenza ngayiphi injongo?
• Ukuphulukiswa kwe-UV LED ukusetshenziswa kokusebenzisa ama-Light Emitting Diode ukukhiqiza amandla e-ultraviolet ukwelapha izinto ezisebenzayo zezithombe. Lezi zinto zifaka ama-inks, ukumboza, okunamathisela, neminye imidiya edinga ukuphulukiswa okukhanyayo. Le nqubo yezobuchwepheshe inezimpande ekuphenduleni kwe-photopolymer, ngaleyo ndlela idinga izinto zokuxosha eziqinisa ngemuva kokukhanya kwe-UV ephendulayo. 
• Inzuzo eyinhloko yokusebenzisa ubuchwepheshe be-LED UV ngaphezu kwezibani zendabuko ze-mercury ukulawula. Zikhiqiza ukushisa okuncane, zinesikhathi sokuphila esikhudlwana, futhi zinobungani bemvelo. 

Inqubo eningiliziwe ye-LED UV Curing

Njenganoma iyiphi enye indlela yokuphulukisa, ukuphulukiswa okuholwa yi-UV kunokuhamba komsebenzi okuthile, okungaba lula kube izinyathelo eziyisisekelo. 

• Umthombo wesibani se-LED:

Iqukethe isibani se-UV esakhiwe ngokukhethekile ukuhlinzeka ukukhanya kwe-UV okudingekayo kwe-365 nm, 385 nm, 395 nm, noma i-405 nm.

• Ukwenza kusebenze abaqali bezithombe:

Endabeni yeyinki, ukumboza, noma ukunamathela, izithako ze-Photo initiator zimunca amandla avela ekukhanyeni kwe-UV.

• Ukusabela kwe-Polymerization:

Ama-triggers phakathi nesinyathelo ngasinye senqubo aqala ukusabela kweketanga, okubuye kwenze i-polymerize impahla.

• Ukwelashwa kwenziwe:

Izinto ezibonakalayo ziphenduka ziqinile ngemizuzwana ngaphandle kokushisa, ukuhwamuka, noma ukudinga noma yisiphi esinye isilinganiso sokubambezeleka.

Izingxenye ze-LED UV Curing

Kunezinto ezintathu eziyinhloko zohlelo lokuphulukisa lwe-UV LED. Bheka izici eziyinhloko ezibandakanyekayo lapha:

• I-Infrared LED Lamp: Yakha ama-Ultraviolet Frequencies athile ukuze aphulukise ngokunembile.
• Uhlelo lokupholisa: Igcina izinga lokushisa (umoya noma amanzi)
• Iyunithi Yokuphakelwa Kwagesi: Ilawula izinga lokukhishwa kwe-conductance (njenge-W / cm²).
• I-Lens: I-Optical / Reflector - ukusika
• Conveyor / Curing Chamber: Ukuze ezokuthutha usebenzisa isivinini zezimboni

Kungani uhamba nge-UV ye-LED ngaphezu kwezindlela ezijwayelekile zokuphulukisa i-UV?

Kuyini ukwelashwa kwe-LED UV? I-UV ye-LED ngokushesha iba indinganiso engcono kakhulu emikhakheni ehlukahlukene, kufaka phakathi ukuphrinta, ukumboza, kanye ne-elekthronikhi, futhi ngesizathu esihle. Uma uyiqhathanisa nezinhlelo ezindala ze-mercury UV, izinhlelo ze-LED zinezinzuzo eziningi ze-eco-friendly.

• Okokuqala, izinhlelo ze-UV ze-LED zikhiqiza imiphumela esheshayo ngaphandle kwegebe lokushisa lapho kudingeka, kanti izibani ze-mercury UV zingathatha imizuzu eminingi. Lokhu, futhi, kwandisa izinga lokukhiqiza ngenkathi kusindisa isikhathi esibalulekile sokusetha.
• Okwesibili, ukonga amandla kungenye yezinzuzo ezivelele kakhulu. Izinhlelo ze-LED zisebenzisa amandla amancane ngenkathi zithola ukuphulukiswa okuphezulu, ngaleyo ndlela zinciphise izindleko zakho zikagesi kanye nekhabhoni yekhabhoni. Ngaphezu kwalokho, i-UV ye-LED ikhiqiza ukushisa okuncane kakhulu, okufanelekile kakhulu ezintweni ezibucayi njengamafilimu, amapulasitiki, namalebula.
• Izinhlelo ze-UV ze-LED ziyi-mercury ne-ozone-free okwandisa ukuphepha emsebenzini futhi kunciphise izingozi zemvelo. Ngokuphambene nalokho, izibani zendabuko ze-UV zikhipha i-ozone futhi ziqukethe i-mercury, ngakho-ke kufanele ziphathwe ngokukhethekile futhi zilahlwe.
• Impilo yesibani ibuye ibe yimpumelelo ye-LED UV, ehlala amahora angaphezu kwama-20,000 ngokungafani ne-1,000-2,000 ye-mercury UV. Lokhu kuhumusha izindleko eziphansi zesondlo kanye nokunciphisa isikhathi sokukhiqizwa. 
• Sekukonke, ukuphulukiswa kwe-UV kwe-LED empeleni kuhlanzekile, kupholile, futhi kubiza kakhulu, kufakazela ukuthi kuyindlela engcono kakhulu uma kukhulunywa ngezwe lanamuhla lokukhiqiza eliqaphela imvelo. 

Izinzuzo ze-LED UV Curing 

Manje ake sixoxe ngezinzuzo ezisebenzayo: 

1. Ukomisa okusheshayo: Izinto zelapha ngokushesha, okwandisa ijubane lomugqa.

2. Ukonga amandla: Kuze kufike ku-60% ukonga uma kuqhathaniswa nokusetshenziswa kwesibani se-mercury.

3. Ukukhishwa kokushisa okuphansi: Ifanele ama-substrates azwela ukushisa njengamafilimu amancane namapulasitiki.

4. Ikhwalithi Yokuphrinta Ethuthukisiwe: Ukuphulukisa ngokuqinile nangokunembile kwandisa ubukhali be-footage nokucwebezela.

5. I-Compact ne-Modular: Lezi zibani ze-UV ze-LED zingafakwa kalula, zincane ngosayizi, futhi zinganwetshwa kalula.

6. Isikhathi sokuphumula esithuthukisiwe: Ukugcinwa okuncane futhi akukho zikhathi zokushisa noma zokupholisa,

7. Ukuncishiswa kwe-VOC: Kungcono ku-opharetha kanye nemvelo.

Izimboni ezisebenzisa ukuphulukiswa kwe-UV ye-LED

Ngenxa yokuguquguquka kwayo, ukuphulukiswa kwe-UV ye-LED kusetshenziswa ezimbonini ezahlukahlukene: 

• Ukuphrinta 

•          Ukuphrinta kwedijithali 

•          I-Flexographic ne-Offset 

•          Ukuphrinta kwesikrini se-UV LED 

•          Ukupakisha (ucwecwe, ipulasitiki, iphepha) 

• Adhesives & Coatings 

•          Amajazi okuvikela nokuvikela

phezulu

•          Ukuqeda izinkuni kanye ne-laminate yokuhlobisa

•          Ukubopha kokunamathisela kwezimboni

• Ezokwelapha ne-elekthronikhi 

•          Ukumbozwa kwamadivayisi wezokwelapha

•          Ukumbozwa kwe-Conformal kwama-PCB 

•          Ukubopha kwe-optical kwe-microelectronics 

•          Ukubekwa uphawu kwe-Microelectronics

• Ukuphrinta kwe-3D

•          Iphrinta ye-3D esekwe kwi-photopolymer, ukuphulukiswa kwe-UV ye-LED

•          Ukuphrinta okuqinile futhi okuhlala isikhathi eside ngaphandle kokulibaziseka ngemuva kokuphulukiswa 

Ungayikhetha kanjani imishini efanele yokuphulukisa i-UV LED?

Ukuze ugcine ukusebenza kahle kakhulu, ukusebenza kahle kokukhiqiza, nokuphulukisa ukungaguquguquki, uhlelo olufanele lokuphulukisa lwe-UV LED kufanele lukhethwe ngokucophelela. Cabanga ngalezi zici ezilandelayo ngaphambi kokuthenga:

1. Ukuphulukisa ama-wavelengths 

Ama-activators ahlukahlukene aphendula kuma-wavelengths ahlukene. Ama-inki amaningi nama-adhesives aphendula kuma-wavelengths we-UV 365nm, 385nm, 395nm, 405nm, njalonjalo. Njalo hlola ukuthi ngabe ubude besibani se-UV LED kanye nokwakhiwa kwamakhemikhali kwezinto ezibonakalayo kuyahambisana yini ukuthuthukisa ukwelashwa.

2. Amandla okukhipha

Ukukhanya, okuchazwe ngamandla okukhipha (W / cm²) kunquma ukujula kwezinto ezibonakalayo kanye nesivinini sokwelashwa. Izinhlelo ze-UV LED zamandla aphezulu zibalulekile ukuqinisekisa i-polymerization esheshayo ngaphandle kokunciphisa ukumbozwa okukhulu nezinqubo zokuphrinta ezisheshayo.

3. Ububanzi bokwelapha 

Ububanzi bokwelapha kufanele futhi bukhethwe ngokulandela ububanzi be-substrate. Amakhanda amancane e-UV LED alungele amaphrinta amalebula namadivayisi e-elekthronikhi, kuyilapho lawo asetshenziselwa ukumbozwa kwezimboni, ukuphrinta kwebhanela, nokubhala izimpawu kudinga izinhlelo zefomethi ebanzi.

4. Ukupholisa okudingekayo

Izinhlelo zokusebenza ezizimele noma ezincane zingasebenza kangcono ngamadivayisi we-UV LED apholile emoyeni; Kodwa-ke, izinhlelo ezinokupholisa kwamanzi zinconywa kuzilungiselelo eziphezulu noma eziqhubekayo ze-pulse zokuphila kwesibani isikhathi eside nokusebenza okwandisiwe.

5. Ukuhlanganiswa Kwesistimu

Qiniseka ukuthi idivayisi yakho ingafakwa kalula emshinini wakho. Bheka ugesi, ukuhlanganiswa kohlelo lokulawula, nezinyathelo zokwengeza ze-modular ukuze kuhlanganiswe kalula.

Isiphetho:

Kuyini ukwelashwa kwe-LED UV? Kungaphezu kwenqubo yokomisa; Kuyindlela ehlakaniphile, eluhlaza okwesibhakabhaka, futhi esheshayo yokuqinisa ama-inks, ama-adhesives, nokumboza. Kunoma yimuphi umkhakha okuwo, kungaba ukuphrinta, i-elekthronikhi, amadivaysi ezokwelapha, noma ngisho nokukhiqiza kwe-3D, uzoqaphela ukuthi ubuchwepheshe be-UV LED abunakuqhathaniswa ngokunemba, ukusebenza kahle, nokusimama. Imiphumela esheshayo ngaphandle kwe-mercury noma ukulinda, ikhwalithi ekhazimulayo kuphela nokusebenza kwesikhathi esizayo. Vakashela UVET.
