Kungani Isibani se-UV Sishisa Ngesikhathi Senqubo Yokuphulukisa?
2025-11-19
Emikhakheni yezimboni efana nokunyathelisa, ukupakisha, kanye nokugqoka izinkuni, Ukwelashwa kwe-UV Ubuchwepheshe busetshenziswa kabanzi ngenxa yokusebenza kahle kwabo, ubungane bemvelo, kanye nekhwalithi enhle kakhulu. Kodwa-ke, nakuba abasebenzisi bezuza kalula, bavame ukuqaphela futhi baveze ukukhathazeka ngamazinga okushisa aphezulu akhiqizwa isibani se-UV nezindawo ezizungezile. Ake sihlolisise izimiso zesayensi ezingemuva kwalesi simo.
Ukuguqulwa Kwamandla Kuyisizathu Esiyinhloko:
Ingqikithi ye Ukwelapha i-UV ukusetshenziswa kwamaza athile okukhanya kwe-ultraviolet ukuze kuqaliswe ukuxhumanisa okusheshayo kanye nokuqedwa kwe-uyinki noma izembozo eziqukethe ama-photoinitiators. Kule nqubo, isibani se-UV sisebenza njengomthombo wamandla, siguqula ugesi ongenayoamandla ngokuyinhloko abe izinhlobo ezimbili: Eyokuqala imisebe ye-ultraviolet, okuyiwona mandla asebenzayo abangela ukuphiliswaUkusabela kwesibili ukukhanya okubonakalayo kanye nemisebe ye-infrared; i-infrared isebenza njengemisebe yokushisa, emuncwa yizinto futhiiguquka ngokushesha ibe amandla okushisa. Lesi yisizathu esiyisisekelo sokwenyuka okukhulu kwezinga lokushisa emzimbeni wesibani kanyeindawo ezungezile.
Isibani ngokwaso siwumthombo wokushisa:
Uma sibheka izibani ze-mercury ezivamile ezinomfutho ophakathi njengesibonelo, isimiso sazo sokusebenza sihilela ukusebenzisa i-arc kagesi enomfutho ophakemengaphakathi kwepayipi lesibani ukuze kuvuse umusi we-mercury, okubangela ukuthi ukhiphe ukukhanya. Izinga lokushisa eliyinhloko lale arc lingafinyelela ezinkulungwaneni ezininganaamadigri Celsius. Ngisho noma ihlukaniswe udonga lweshubhu le-quartz, izinga lokushisa lokusebenza kwalo livame ukuhlala liphakeme lifike ku-600-800°C.Isibani esinjalo, esikhipha ukushisa okukhulu njalo, ngokungenakugwenywa siphakamisa izinga lokushisa lendawo esizungezile ngokushisaimisebe kanye ne-convection yomoya.
Umthelela Ohlangothini Olubili Wokushisa Okuphezulu:
Izinga lokushisa eliphakathi lingakhuthaza ukusabela kokuphola, kodwa izinga lokushisa eliphakeme kakhulu liletha izinkinga eziningi kunezinzuzo.akugcini nje ngokubangela ukuguquka kokushisa kwamapulasitiki afana ne-PVC ne-PET, noma kuholele ekulahlekelweni komswakama kanye nokugoba kwezingxenye zephepha, kodwa kungabangelafuthi kubangela ukuphola kwangaphambi kwesikhathi kobuso, okuvimbela ukuphola kwangaphakathi okujulile futhi okungase kuthinte ukunamathela. Ngaphezu kwalokho, ukwanda kokuphola kwangaphandleizinga lokushisa elizungezile le-workshop lithinta induduzo yokusebenza futhi lenezela izindleko zokupholisa ezengeziwe.
Ukuphathwa Kokushisa Okuhlelekile kuyisisombululo Esiyinhloko:
Ngakho-ke, izinga lokushisa eliphezulu liyinto ebonakalayo enqubweni yokuguqulwa kwamandla yokwelapha i-UV, hhayi imishiniukungasebenzi kahle. Ngakho-ke, ukuphathwa kokushisa kwesayensi kubalulekile. Ikhwalithi ephezulu yesimanje Uhlelo lwe-UVhlanganisa izixazululo ezithuthukisiwe njengomoyaukupholisa, ukupholisa amanzi, kanye nezibonisi ezipholile ezikhethekile. Lokhu kuhlose ukwandisa ukubonakaliswa kokukhanya kwe-UV ngenkathi kulawulwa ngempumeleloukushisa kwe-infrared, okuqinisekisa ukuphiliswa okuphumelelayo ngenkathi kunciphisa umthelela wokushisa, ekugcineni kufinyelela ibhalansi enembile phakathi kokukhanya kanyeukushisa.
