Ko te tikanga, ko te tānga UV e whai ake nei i ngā momo hangarau:
1. Taputapu Pūtake Mārama UV
Kei roto i tēnei ko ngā rama, ngā whakaata, ngā pūnaha whakahaere pūngao, me ngā pūnaha whakahaere pāmahana (whakamatao).
(1) Ngā Rama
Ko ngā rama UV e whakamahia whānuitia ana ko ngā rama kohu mercury, kei roto i te ngongo te mercury. I ētahi wā, ka tāpirihia ētahi atu konganuku pēnei i te gallium hei whakatika i te putanga hihi.
E whakamahia whānuitia ana hoki ngā rama whakarewa-haura me ngā rama kuata, ā, he maha tonu e kawemai ana.
Me taka te awhe roanga ngaru e tukuna ana e ngā rama whakamaroke UV i waenga i te 200–400 nm kia whai hua ai mō te whakamaroke.
(2) Ngā Whakaata
Ko te mahi matua a te whakaata he whakahoki i te hihi UV ki te papa hei whakanui ake i te pai o te whakamaroke (UV Tech Publications, 1991). Ko tētahi atu mahi nui ko te āwhina ki te pupuri i te pāmahana mahi rama e tika ana.
Ko te tikanga he konumohe te mea hanga o ngā whakaata, ā, ko te kaha whakaata e hiahiatia ana kia eke ki te 90%.
E rua ngā hoahoa whakaata taketake: he arotahi (porowhita) me te kore arotahi (parabolic), me ētahi atu momo rerekē i whakawhanakehia e ngā kaihanga.
(3) Ngā Pūnaha Whakahaere Pūngao
Mā ēnei pūnaha ka noho pumau te putanga UV, ka mau tonu te pai me te ōrite o te whakamaroke me te urutau ki ngā tere tā rerekē. Ko ētahi pūnaha ka whakahaerehia e te hiko, ko ētahi ka whakamahia te mana rorohiko moroiti.
2. Ngā Pūnaha Whakamatao
Nā te mea ehara i te mea ko te hihi UV anake ka tukuna e ngā rama UV engari ko te wera infrared (IR) hoki, ka mahi ngā taputapu i ngā pāmahana teitei (hei tauira, ka taea e te pāmahana mata o ngā rama quartz te eke ki ngā rau nekehanga Celsius).
Ka taea e te wera nui te whakapoto i te roa o te ora o te taputapu, ā, ka puta pea te whānui, te rerekē rānei o te papa, ka puta ai ngā hapa rēhita i te wā e tā ana. Nō reira, he mea tino nui ngā pūnaha whakamatao.
3. Pūnaha Tuku Waituhi
Ki te whakaritea ki ngā waituhi ōwehenga tuku iho, he nui ake te matotoru me te waku o ngā waituhi UV, ā, ka pakaru pea ngā wāhanga mīhini pēnei i ngā paraikete me ngā roera.
Nō reira, i te wā e tā ana, me whakaoho tonu te waituhi i roto i te puna, ā, me hanga ngā roera me ngā paraikete i roto i te pūnaha waituhi hei rauemi i hangaia mō te tānga UV.
Hei pupuri i te pumau o te waituhi me te ārai i ngā huringa matotoru e pā ana ki te pāmahana, he mea nui anō hoki ngā pūnaha whakahaere pāmahana roera.
4. Ngā Pūnaha Whakakore Wera me te Puta
Ka tangohia e ēnei pūnaha te wera nui me te ozone i puta i te wā o te whakapūhui me te whakamaroke i te waituhi.
I te nuinga o te wā he motuka whakaputa hau me te pūnaha paipa.
[Ko te whakaputanga o te ozone e pā ana ki ngā roangaru UV i raro i te ~240 nm; he maha ngā pūnaha hou e whakaiti ana i te ozone mā roto i ngā pūtake tātari, LED rānei.]
5. Ngā Waituhi Tā
Ko te kounga o te waituhi te mea tino nui e pā ana ki ngā hua tānga UV. Haunga te pānga ki te whakaputa tae me te whānuitanga tae, ko te āheinga tā o te waituhi te mea e whakatau tika ana i te piri, te kaha, me te ātete ki te pakū o te tānga whakamutunga.
He mea nui ngā āhuatanga o ngā kaiwhakaahua me ngā monomer ki te mahi pai.
Hei whakarite i te piri pai, ina pā te waituhi UV mākū ki te papa, me teitei ake te kukū o te mata o te papa (dynes/cm) i tērā o te waituhi (Schilstra, 1997). Nō reira, ko te whakahaere i te kukū o te mata o te waituhi me te papa he hangarau matua i roto i te tānga UV.
6. Ngā Pūrere Ine Pūngao UV
Nā te mea ka pāngia te whakamaroketanga e ngā āhuatanga pēnei i te tawhito o te rama, te rerekētanga o te mana, me ngā panonitanga o te tere tā, he mea nui kia aroturukihia, kia mau tonu hoki te putanga pūngao UV. Nō reira, he mea nui te hangarau ine pūngao UV i roto i te tānga UV.
