Umgaqo osisiseko weSolarium Tanning Bed uxhomekeke ekulinganisweni kwemisebe ye-ultraviolet, ekhuthaza ukwenziwa kwe-melanin eluswini ngemisebe ye-UV yobude obumiselweyo, ngaloo ndlela kuvelisa isiphumo sokuthamba esifana nesokukhanya kwelanga. Oku kulandelayo yinkcazo eneenkcukacha yemigaqo yayo ephambili:
1. Umgaqo-nkqubo wesayensi wemitha ye-ultraviolet (UV) kunye nenkqubo yokuthambisa ulusu.
Isincoko esilandelayo siza kunika inkcazelo eneenkcukacha ngendlela yokuveliswa kwe-melanin.
Xa ulusu luvezwa kwimitha ye-ultraviolet (UV), ii-melanocytes kwi-epidermis ziyavuselelwa kwaye zivelise i-melanin ukuze zifunxe imitha kwaye zikhusele izicubu ezinzulu zolusu ekonakalisweni. Inkqubo yokuqokelelana kwe-melanin ibangela ukuba ulusu lube mnyama, nto leyo ekhokelela ekudalweni kwesiphumo "sokuthambisa".
Iibhendi eziphambili ze-ultraviolet:
I-UVA (320–400 nm):
Kuye kwabonakaliswa ukuba inezakhono ezibalulekileyo zokungena, kunye namandla okufikelela kwi-dermis. Isiphumo esiphambili sokusetyenziswa kwale nto kukukhuthaza i-oxidation kunye nobumnyama be-melanin ekhoyo, okubangela ukuba i-tan ibonakale ngokukhawuleza. Nangona kunjalo, kubalulekile ukuqaphela ukuba ukuvezwa kakhulu kwimitha yelanga ixesha elide kuya kubangela ukuguga kwesikhumba.
I-UVB (290–320 nm):
Iimpawu zale khompawundi ziquka ukungena okungacacanga, ukukhuthaza ukwanda kwe-melanocyte, kunye nokuveliswa kwe-melanin entsha (ukucotha kwesikhumba). Nangona kunjalo, kubalulekile ukuqaphela ukuba ukuchatshazelwa kakhulu lilanga kunokubangela ukutsha lilanga.
2. Le ngxelo ilandelayo iza kuphonononga iinkalo zobuchwepheshe boomatshini bokushushumbisa.
Uhlu lomthombo wokukhanya:
Isibane se-fluorescent:
Uninzi lwezi matshini zokuthambisa i-tan zisebenzisa izibane ze-fluorescent ezineengubo ze-phosphor, ezisebenzisa umbane ukuvuselela ukukhutshwa komphunga we-mercury, ngaloo ndlela zikhupha i-UV. Ububanzi be-UV ekhutshwayo buyahluzwa kwaye bulungiswe (umzekelo, i-90% ye-UVA + i-10% ye-UVB) ngokusebenzisa i-coating.
Izixhobo zamva nje ezisetyenziswayo ngumthombo wokukhanya kwe-UV ye-LED.
Kuyacaca ukuba isixhobo esixoxwayo siphawulwa kukuchaneka okuphuculweyo ngokubhekiselele kulawulo lwamaza, kunye nokusetyenziswa kwamandla okuncitshisiweyo. Nangona kunjalo, kufuneka kuqatshelwe ukuba oku kuhamba kunye nokunyuka kweendleko ngaxeshanye.
Umxholo wolawulo lwemitha uxoxwa apha.
Ngokuhlengahlengisa iiparameter ezifana nenani lezibane, amandla, kunye nexesha lokuvezwa, kufunyanwa ulungelelwaniso phakathi kwesiphumo sokutshiswa kwelanga kunye nokhuseleko.
Izixhobo zamva nje ezikumgangatho ophezulu zixhotyiswe ngesixhobo sokuvavanya uhlobo lolusu esilungisa ngokuzenzekelayo idosi ye-UV (umz. ngokwesikali seFitzpatrick).
3. Oku kulandelayo kukwahluka okuphawulekayo phakathi kwesi simo kunye nokukhanya kwelanga kwendalo:
Ezi zinto zilandelayo kufuneka zithelekiswe: umatshini wokuthambisa isikhumba kunye nokukhanya kwelanga kwendalo.
Ibhendi ye-UV inokwenziwa ngokwezifiso, kunye nokhetho lwe-UVA ephuculweyo. I-spectrum epheleleyo iquka i-UVA, i-UVB kunye ne-UVC.
Ubukhali bokukhanya buyakwazi ukulawulwa, kwaye buqhele ukuba phezulu kunobo belanga lasemini. Bunokwahluka ngenxa yeemeko zemozulu kunye nendawo ekuyo.
Ixesha lokuvezwa lidla ngokuba lixesha elichanekileyo, ukusuka kwimizuzu eli-10 ukuya kwengama-20. Nangona kunjalo, kunzima ukulawula.
Iingozi:
Ukusetyenziswa kakhulu kwale mveliso kunokukhokelela ekufoteni ngokulula, oko kukuthi, inkqubo yokwakheka kwemibimbi ngaphambi kwexesha.
Ubuthathaka be-ozone layer bunyusa umngcipheko wokuvezwa yi-UVB.
4. Isihloko esixoxwa ngaso singokhuseleko kunye nempikiswano.
Iingozi ezinokubakho:
Kubalulekile ukuqaphela ukuba ukusetyenziswa rhoqo kuye kwanxulunyaniswa nomngcipheko ophezulu womhlaza wolusu (umz. i-melanoma) kunye nokuguga ngefoto (umz. imibimbi, amabala).
Kwamanye amazwe, imiqathango yokusetyenziswa kwezixhobo zokuthambisa isikhumba iye yaphunyezwa, apho iOstreliya ingumzekelo ophawulekayo womthetho onjalo, ithintela ukusetyenziswa kwezorhwebo koomatshini bokuthambisa isikhumba.
Ingcebiso yokhuseleko:
Ukuze uphephe ukuvezwa kwiindawo ezibuthathaka, kubalulekile ukuba unxibe izibuko zokukhusela amehlo.
Kubalulekile ukunamathela ngokungqongqo kwixesha elicetyiswayo kwaye ungasebenzisi izihlandlo ezininzi ngexesha elifutshane.
