Isebenza kahle kangakanani ukuphulukiswa kwendawo ye-UV? Izimiso Zezimboni

Kuyini ukusebenza kahle kwe-UV LED Area Curing?

Ukusebenza kahle kangakanani ukwelashwa kwendawo ye-UV? Izinhlelo zokuphulukisa indawo ye-UV zithuthukise i-photopolymerization, futhi lezi zinhlelo zithola ukwamukelwa kuyo yonke imikhakha efana ne-elekthronikhi, izimoto, ukuphrinta, nokukhiqizwa kwamadivayisi wezokwelapha ngenxa yezindleko zazo eziphansi, ukuthembeka, ukusebenza kahle kwamandla kanye nesivinini sokwelapha okusheshayo. Kulokhu, sizongena emininingwaneni yokusebenza kwayo, amamethrikhi okusebenza ayisihluthulelo, amacala okusebenzisa, izinzuzo, neminye imininingwane ehlobene nalobu buchwepheshe bokwelapha obuthuthukayo.

UV LED Area Curing Overview

Ukuphulukisa indawo ngama-LED e-UV, izinto ze-photosensitive ziphulukiswa kusetshenziswa ukukhanya kwe-ultraviolet kusuka emithonjeni ye-LED endaweni ekhethiwe. Ngokungafani nokuphulukiswa kwendawo, inendawo ebanzi yokusebenza. Le ndlela ilungele kangcono ukumboza, ama-substrates ayisicaba, ama-adhesives, nama-inks.

Into esemqoka yale ndlela yi-photopolymerization. Kuyinqubo eqalwe ukukhanya kwe-UV ebangela ukuthi izinto eziwuketshezi ziqine cishe ngokushesha ngokusabela kwamakhemikhali.

Iyini inzuzo yokusebenzisa i-UV LED phezu kwezibani ze-mercury? 

Nazi izinzuzo izinhlelo ze-UV LED ezinazo ngaphezu kwezibani ze-mercury vapor: 

• Asikho isikhathi sokushisa esidingekayo sokushintsha okusheshayo kokuvula / ukuvala 

• Amahora angaphezu kwama-20,000 okusetshenziswa kusho isikhathi eside sokuphila 

• Ukunciphisa ukusetshenziswa kwamandla ngenkathi usebenza emazingeni okushisa apholile, alungele izinto ezibucayi. 

Ukusebenza Kwamamethrikhi Ayisihluthulelo

1. Cure Speed 

Ukukhiqizwa kwezinqubo zebhizinisi kukhuliswa kakhulu ngokusetshenziswa kwezinhlelo ze-UV LED ukwelapha izinamathiselo nokugqoka, njengoba kungenziwa ngama-milliseconds. Lokhu kuholela ezikhathini ezimfushane zomjikelezo. 

• Thatha, isibonelo, izinamathiselo ezisuselwa ku-acrylic, eziphulukiswa ngokuphelele ngaphansi komzuzwana ongu-1 ngokuchayeka kuma-LED angama-395nm ane-irradiance ye-200 mW / cm². 

2. Ukujula Ukwelapha 

I-ukusebenza kahle kokujula kokwelapha kuncike ekukhanyeni nasekuphazamiseni kwamagagasi. Ubude obufushane be-wavelength, ikhono lokungena lingcono (isibonelo, i-365nm), ngakho-ke kungcono izingqimba ezijiyile. 

3. Ukusebenza kahle kwamandla

Ngezinhlelo ezisuselwa ku-mercury bulb, izinhlelo ze-UV LED zinikeza i-70% yokusebenza kahle kwamandla.

• Ukusebenza kahle kwama-arrays anamuhla kungadlula ama-30% kagesi-to-optical, ngaleyo ndlela kunikeze ithuba elikhulu lokusebenza kwamandla okuphelele.

4. Umthamo kanye ne-Irradiance 

• Ukukhanya: Kulinganiswa njengamandla amandla anikezwa endaweni ethile (mW / cm²).

• Umthamo: Ukulinganisa amandla asetshenzisiwe futhi alethwa ngokuhamba kwesikhathi (mJ / cm²).

Njengakwezinye izinqubo eziningi, i-automation idinga ukungaguquguquki, futhi lokhu kufezwa kangcono ngokukhanya okuphezulu okufanayo ebusweni. 

5. Ukufana kokwelashwa 

Ukusebenzisa ukuphulukiswa kwendawo ye-UV LED nge-optics eqondile kukhiqiza ukufana kwensimu yokuchayeka okungaphezu kwe-90%. Le bhalansi inciphisa ukwelashwa okuphansi nangokweqile, ngaleyo ndlela kunciphise ukukhubazeka.
