Umgomo Wokwelapha we-UVLED

Okubizwa ngokuthi ukwelapha kwe-UVLED ukwengeza izimbangela zokukhanya ku-resin ngendlela ekhethekile. Ngemva kokumunca ukukhanya kwe-ultraviolet okunamandla aphezulu kudivayisi yokwelapha ye-UVLED optical, kukhiqizwa ama-radicals mahhala asebenzayo noma izisekelo ze-ion, okubangela ukuhlanganisa, ukuxhumanisa okuphambene namagatsha ukuthi asabele, ukuze isiphehli se-resin senze inhlaka (upende we-UV, uyinki, okunamathelayo, njll.) ukusuka oketshezini kuya esimweni esiqinile emizuzwaneni embalwa. Izici ezingokomzimba zezinto zokwelapha ze-UVLED zithinteka kakhulu yimishini yokwelapha ye-UV -optical. Ukusebenza okulindelekile, kungakhathaliseki ukuthi kuvikela iglue, uyinki, noma i-adhesive, kuzoncika kumapharamitha, umklamo nezindlela zokulawula zama-chips e-LED kule mishini yokwelapha. Imingcele emine ebalulekile ye-chip ye-LED yilezi: 1.UV radiation (noma ukuminyana) 2. ukusatshalaliswa kwe-spectral (ubude begagasi) 3. Imisebe (noma amandla e-UV) 4. Ukushisa kwemisebe kuhlobene nemisebe emikhulu noma ivolumu yemisebe, futhi ehlukene, futhi ehlukene i-spectrum ye-UVLED, uyinki neglue evikelayo izobonisa izici ezihluke kakhulu. Ikhono lokuhlonza izici ezihlukile ze-chip ye-LED nokuzenza zifane nezici zokubona zezinto zokwelapha, nokwandisa ububanzi bokuqiniswa kwe-UVLED njengenqubo yokukhiqiza esheshayo nephumelelayo. Kunezinto eziningi ezibonakalayo nezingokomzimba zesistimu yokwelapha ezithinta umphumela wokuqiniswa, okuholela kumehluko ezicini zokubukeka zezinto zokuphulukisa ze-UV. Umthelela wamapharamitha ahlobene kukhwalithi yokwelapha ye-UV 1. Ubude begagasi bomshini we-UVLED: I-spectrum yebhendi engu-365nm ifanele uyinki ojwayelekile wokwelapha obonakalayo (awufanele uyinki odingwa izibukeli ezikhethekile njengezimbali zeqhwa nemibimbi). Eminye imishini ye-UV miningi kakhulu ngenxa yethonya le-chip ye-LED, ezothinta umphumela oqinile wokukhanya. Kunconywa ukuthi amakhasimende enze izivivinyo eziqinile ezikhanyayo lapho ekhetha amadivaysi okulungisa ukukhanya kwe-UV ukuze ahlole ukuthi ubude beza beza bomshini we-UV buhlangabezana yini nezidingo eziqinile ezibonakalayo. 2. Amandla omshini we-UVLED: Ngokujwayelekile, amandla adingwa yi-UV optical inki ngu-80-120MW/CM, futhi amandla okukhanya amuncayo angaba ngu-2000 3000mJ/cm. Amandla okukhanya okweqile angabangela ukonakala kukayinki. Umphumela oqinile wokukhanya ophansi. Isibonelo sohlelo lokusebenza izici ezibonakalayo zemisebe ye-UV zifana nokukhanya okubonakalayo, konke okuqondile, kodwa amandla azo okungena awabonakali kakhulu. Lapho ubude begagasi buba bufishane, amandla okungena aba mabi kakhulu. Ukwelapha kwangaphakathi ngokudluliswa kokukhanya okungcono. 1. Ukukhanya kwe-UV kukhiqiza i-UV ngenkathi kukhiqiza ukushisisa okuthile kwe-IR. Lo mkhuhlane we-radiation unenzuzo ezintweni zokusebenza ezinezinga lokushisa elincane. Kulindeleke ukuthi umphumela ubonakale kakhudlwana. Isibonelo sohlelo lokusebenza: Upende we-UV wezitezi zokhuni, imikhiqizo yensimbi, njll.; I-UV insulation coatings kumabhodi wesifunda aphrintiwe; Iglue ye-UV emikhiqizweni yengilazi. 2. Ithonya lokushisa lizwela kakhulu noma izingxenye zamakhemikhali ezimelana nezinga lokushisa ezinokumelana okuphansi kwezinga lokushisa. Ukunciphisa ukushisa kwemisebe ye-IR kungenye yezihloko eziphambili zemishini yokwelapha ye-UV emazweni ahlukahlukene emhlabeni. Ngokuvamile, isetshenziselwa ukusebenzisa ukupholisa amanzi, i-reflection, ukuhlunga imvamisa nezinye izindlela. Ixazululiwe, kodwa izindleko amandla okukhanya kwe-ultraviolet okufanele alahleke. Izibonelo zohlelo lokusebenza: Ama-PVC ahlukahlukene (njengamakhadi e-IC), ifilimu yepulasitiki, i-Ke (outlet) ukuphrinta uwoyela we-UV, ukuphrinta okukhethekile kwephepha (imbali yeqhwa), ukuphrinta kwekhibhodi yekhompyutha.
