Igumbi lovavanyo lokuguga le-UV lisetyenziswa ikakhulu ukulinganisa umonakalo welanga lendalo, ukufuma, kunye nobushushu kwizinto eziphathekayo.Ukuguga kwezinto kubandakanya ukufiphala, ukulahleka kweglosi, ukuxobuka, ukutyunyuzwa, ukunciphisa amandla, ukuqhekeka, kunye ne-oxidation.Ngokulinganisa ukukhanya kwelanga, ukujiya, kunye nokufuma kwendalo ngaphakathi kwebhokisi, inokuvavanywa kwindawo elinganisiweyo kangangeentsuku okanye iiveki ezininzi ukuvelisa kwakhona umonakalo onokuthi wenzeke phakathi kweenyanga okanye iminyaka embalwa.

Ukukhanya okukhutshwe yityhubhu yesibane yegumbi lovavanyo lokuguga le-UV kunokubonelela ngokukhawuleza iziphumo zovavanyo.Ukukhanya okufutshane kwe-ultraviolet esetyenzisiweyo kunamandla xa kuthelekiswa nezinto eziqhelekileyo emhlabeni.Nangona i-wavelength ekhutshwa ngamatyhubhu e-ultraviolet imfutshane kakhulu kune-wavelength yendalo, ukukhanya kwe-ultraviolet kunokukhawuleza kakhulu ukuvavanywa, kodwa kunokubangela ukungahambelani kunye nokwenyani umonakalo wokuthotywa kwezinto ezithile.

ityhubhu ye-UV sisibane semercury esinoxinzelelo oluphantsi olukhupha ukukhanya kwe-ultraviolet xa sivuselelwa nge-low-pressure mercury (Pa).Yenziwe ngeglasi yequartz ecocekileyo kunye nekristale yendalo, enezinga eliphezulu lokungena kwe-UV, ngokuqhelekileyo lifikelela kwi-80% -90%.Amandla okukhanya adlula kude lee iityhubhu zeglasi eziqhelekileyo.Nangona kunjalo, ekuhambeni kwexesha, iityhubhu zesibane zilungele ukuqokelela uthuli.Ngoko, kufuneka iityhubhu zokukhanya zicinywe rhoqo?

Okokuqala, ngaphambi kokusebenzisa ityhubhu yesibane entsha, inokusulwa nge-75% yebhola yomqhaphu yotywala.Kunconywa ukuba usule rhoqo kwiiveki ezimbini.Ngethuba nje kukho uthuli okanye amanye amabala phezu kombhobho wesibane.Kufuneka kusulwe ngexesha elifanelekileyo.Gcina iityhubhu zesibane zicocekile ngamaxesha onke.Ukuphepha ukuchaphazela amandla okungena kwimitha ye-ultraviolet.Enye ingongoma kukuba kumagumbi okuvavanya ukuguga kwe-UV, ukugcinwa akufuneki kuphela kwiityhubhu zesibane.Sifanele siyigcine size siyigcine rhoqo le bhokisi.
