Kuyini ukwelashwa kwe-ultraviolet?

Le yindlela yokuphulukisa, lapho ukusabela kuqhutshwa ukukhanya kwe-UV ukwenza lukhuni noma ukwenza i-polymerize into ewuketshezi - okungukuthi, ukunamathela, inki, noma ukumbozwa - kube okuqinile. Lokhu kungafani nenqubo yokushisa, lapho inqubo yokuphulukisa i-UV isebenzisa amandla okukhanya ukuvuselela umsebenzi wama-photoinitiators, ngaleyo ndlela kubangele i-polymerization esheshayo. Le nqubo ibizwa nangokuthi i-photopolymerization, futhi isuselwa ekusetshenzisweni kwama-wavelengths athile e-UV (imvamisa i-365nm, 385nm, 395nm, ne-405nm). Ubude be-wavelength bunquma ukujula kokuphulukisa, isivinini, nokuhambisana kwezinto zokwakha. Ngokuyisisekelo, ukuphulukiswa kwe-UV kuyindlela yokuphulukisa esebenza ngamandla futhi engaxhunyiwe enikeza isenzo sokuphulukisa esibikezelwa ngaphandle kokusonteka kwezinto ezibucayi.

Inqubo Yokuphulukisa ye-UV ichaziwe

Indlela ye-UV yokwelapha iqukethe izingxenye ezintathu ezinkulu:

Umthombo wokukhanya kwe-UV - Imvamisa iyimodyuli yesibani se-LED noma isibani se-mercury esikhipha imisebe ye-ultraviolet elawulwayo.

I-Photoinitiator - Le yinto esebenzayo yesithombe efakwe ekunamathiseleni noma ekuhlanganisweni okuvezwe emisebeni ye-UV futhi yenza ukunamathela kube nzima.

Ama-Monomers / ama-Polymers asebenzayo - yilawo asetshenziselwa ukwakha iwebhu eqinile ngesikhathi senqubo yokuphulukisa nge-UV crosslinking.

Lapho ukukhanya kwe-UV kushaya ubuso bezinto ezibonakalayo, kubangela inqubo yokusebenza kwe-photoinitiator. Lokhu kukhiqiza ama-radicals wamahhala abangela ukuxhumana kwamakhemikhali kwama-monomers ukwakha ama-polymers, akha indawo eqinile, eqinile cishe ngokushesha.

 Technical Insights UV Curing

• Ubuchwepheshe bokwelapha i-UV bulawulwa ekukhishweni kokukhanya nokudluliswa kwamandla.
• Inani lamandla ebusweni libalwa nge-UV irradiance (kulinganiswa ku-mW / cm2).
• Isikhathi sokuvezwa nokukhethwa kwe-wavelength (365nm-405nm) kunomthelela ekujuleni kwe-polymer nokunamathela.
• Amamojula we-LED array avumela ukusatshalaliswa okufanayo kokukhanya ukuze kube nokulawula okuhle kokuphulukisa.

Izinhlelo zokuphathwa zokushisa nazo ziyakwazi ukuvimbela ukushisa ngokweqile ngakho-ke zigcina ukushisa ezingeni eliphansi, ngaleyo ndlela zivimbele isenzo sokushisa ama-substrates abucayi.

Izinhlelo zanamuhla nazo zine-reflector optics kanye namasinki okushisa azinzisa ukusebenza kwezinhlelo futhi aqinisekise ukuthi angagcinwa ngamandla e-UV njalo. Le nhlanganisela ye-physics nobunjiniyela yenza ukwelashwa kwe-UV kungasheshi kuphela kodwa futhi kunokwethenjelwa kakhulu ngokuya ngokukhiqiza ngamavolumu amakhulu.

Izinzuzo ngokuya ngezicelo zezimboni

I-UVET UV LED Curing Device iyi-umshini wokusebenza okuphezulu ngokuguquguquka okuphezulu, okungasetshenziswa ezimbonini eziningi:

Ukukhiqizwa kwe-elekthronikhi

Le yimishini yokuphulukisa esetshenziselwa ukuqinisekisa ukubopha, ukufakwa uphawu, kanye nomhlangano omncane ukunika amandla ukunamathela okuqondile ngaphandle kokuhlanekezelwa okushisayo. Kuhilela inqubo yokuphulukisa engaxhunyiwe ukugcina ubuqotho bezingxenye ezincane kanye nemijikelezo emihle.

Ukukhiqizwa Kwedivayisi Yezokwelapha

Enqubweni yokunakekelwa kwezempilo, isiza ekuhlanganisweni okuphephile nokuhlanzekile kwama-catheter, izindlu, nemishini yokuxilonga. Ukukhishwa okunjalo kokushisa okuphansi kuzoqinisekisa ukuthi izinto ezibucayi azilimazi, futhi ukuziphatha kokwelapha kuyahambisana ne-biocompatible.

I-Optical Bonding ne-Optoelectronics

Lolu hlelo, olungasetshenziswa ezindaweni ezigobile njengoba lungasetshenziswa ezindaweni ezicacile, lungcono kakhulu ekugcineni ukuphulukiswa okufanayo kumalensi, izinzwa nezihlungi.

Ukuphrinta kwe-3D kanye nezinhlelo zokusebenza zokumboza

Endabeni yama-resin aphulukkayo e-UV, ama-inks, nokuqeda, imishini inikeza ukuphulukiswa okubushelelezi kanye nendawo yokumboza ekahle uma kukhulunywa ngokukhiqizwa okungeziwe nokuqeda.

 Izinzuzo zobuchwepheshe zezinhlelo zokuphulukisa ze-UV LED

Izinhlelo zokuphulukisa ze-UV LED, isib, i-UVET, nazo zingcono kunezinhlelo eziphelelwe yisikhathi ezinezibani ze-mercury ngezindlela eziningana:

Ukusebenza okusheshayo: Izibani ze-LED ziba ukukhanya okugcwele lapho zivuliwe - asikho isikhathi sokushisa.

Ukusetshenziswa kwamandla: I-Redundancy Ukusetshenziswa kwamandla = amaphesenti angama-70 uma kuqhathaniswa nezibani ezijwayelekile zokuphulukisa ze-UV.

Imijikelezo Yokuphila Ende: Ama-arrays e-LED ahlala ngaphezu kwamahora angama-20,000.

Okuluhlaza okwesibhakabhaka: Ayikho imfucuza ye-mercury noma i-ozone, ukukhishwa kwe-VOC kuncishisiwe.

Ukulawula okuqondile: Ukuqina kwe-UV kanye nobude be-wavelength yezinto ezahlukahlukene ezingalapheka ziyalawuleka.

Isikhombimsebenzisi esincane: Kulula ukuhlanganisa emigqeni yokukhiqiza ezinhlelweni ezizenzakalelayo, namarobhothi.

Lezi zinzuzo zenza ubuchwepheshe bokwelapha i-Ultraviolet bube yisisombululo esimeme, esingabizi futhi esisebenza kahle ezimbonini zomhlaba wonke.

 Economic Payoff and Environmental

Enye yezinkinga ezikhanga kakhulu zobuchwepheshe bokwelapha i-UV ukusimama kwayo. Ayikhiqizi kakhulu ekukhishweni kwekhabhoni nemfucumfucu enobuthi ngoba ayidingi ukushisa noma ama-solvents.

Izinzuzo ezibalulekile:

• Uhlelo lokwelapha olunokusetshenziswa kwamandla okuphansi.
• Ukukhishwa okuphansi kwe-VOC - okuncane okunobuthi kubasebenzi nasemvelweni.
• Izindleko eziphansi zokugcinwa ngoba impilo ye-LED ihlala isikhathi eside.
• Inqubo yokuphulukisa i-UV ephezulu iholela ekuthuthukiseni ukukhiqiza.

Lezi zinzuzo zingasiza ekunciphiseni ukukhiqizwa okunobungani bemvelo kanye nokusebenza kwezindleko, ngakho-ke, imishini yokuphulukisa i-UV kungukutshalwa kwezimali okunenzuzo nesikhathi eside.

 Amandla okuhlanganiswa nokuzenzekelayo

Imishini yesimanje yokuphulukisa i-UV yenzelwe ukulingana namafektri ahlakaniphile. Kulula ukuhlanganisa nezingalo zamarobhothi, izinhlelo zokuhambisa, nemigqa yomhlangano ezenzakalelayo enemiklamo ye-modular. Amayunithi amancane we-UV aphulukisa kalula uma kuqhathaniswa nemigqa yokuphulukisa ye-UV ezenzakalelayo, enikeza ukusebenza okungaguquguquki. Izinhlelo ezithuthukisiwe zokulawula i-UV ezihlakaniphile zingalawula futhi zilandele imisebenzi emikhulu yezimboni ukude, ngisho nakude.

Ukukhetha isibani sokuphulukisa se-UV noma uhlelo

Lapho ukhetha isibani esifanele kakhulu sokuphulukisa i-UV, kuyafaneleka ukukhumbula ukuthi:

Uhlobo lwezinto ezibonakalayo: Ngokuya ngama-adhesives, ukumbozwa / uyinki kungadinga ama-wavelengths athile e-UV.

Indawo Yokuphulukisa: Vumelanisa indawo yendawo ehambisanayo. Qhathanisa isibani endaweni ye-substrate ngendlela yokuthi imiphumela izohlala ifana.

Ukuzwela ukushisa: ukuzwela. Kufanele kube amasistimu we-UV LED ashisa kakhulu.

Ukonga amandla: Thola izinhlelo ezinemisebe ye-UV futhi ezilawulwa ngamandla.

Uhlelo lokupholisa: Ukuqinisekisa ukuzinza ezimweni lapho umshini uzosetshenziswa isikhathi eside, umshini upholile ngamanzi.

Idivayisi yokuphulukisa ye-UV LED izofanelana kahle kakhulu uma kukhulunywa ngokunemba okuphezulu noma izinqubo eziqhubekayo; izonikeza inhlanganisela yokusebenza, ukuqina, nokonga amandla.

 Yini eyenza ukhethe i-Ultraviolet Curing ngaphezu kwezindlela ezivamile?

Isivinini: Ukwelashwa ngemizuzwana embalwa.

Ukunemba: Ukwelashwa kwasendaweni kusetshenziswa imishayo ye-UV yendawo.

Ukulondolozwa kwamandla: Ukunciphisa izindleko zokusebenza nokunciphisa ukusetshenziswa kwamandla.

Ukuphepha: Awekho amakhemikhali ayingozi, ukushisa okuncane.

Ikhwalithi: Indawo egqoke kahle.

Isiphetho

Ukuphulukiswa kwe-ultraviolet kuyimpumelelo ekucutshungulweni kwezimboni - kuhlanganisa isivinini, ukunemba, nokusimama kubuchwepheshe obulodwa. Noma kunjalo, ukuphulukiswa kwe-UV kokunamathisela noma ama-inks kanye nokubopha kwe-optical, izinhlelo ezikhona zokuphulukisa ze-UV LED zizoholela emiphumeleni emihle kunoma yimuphi umkhakha. Ku-UV LED Curing Device, lokhu okusha kungabonakala ekuhlanganisweni kobubanzi bama-wavelengths anikezwayo, umklamo opholile ngamanzi, kanye nokuma okuncane kwendandatho. Iyaziqhenya ngokwelashwa okuhlanzekile, amandla, nokuthembeka okuhlala isikhathi eside; Ngakho-ke, kufanelekile kakhulu ukubhekana nemvelo yokukhiqiza eyinkimbinkimbi kakhulu.

Hlola amathuba okuphulukisa ubuchwepheshe usebenzisa ukukhanya kwe-ultraviolet futhi uhlole izinga lakho lokukhiqiza ezingeni elisha ngezixazululo ezintsha ze-UVET.
