He aha te Pepa Māpere UV?

一, Whakamaramatanga o te papa UV

I runga i ngā papa matūriki, ngā taera uku, te karāhe hangai, te karāhe, te kiriaku me ētahi atu papa, ka rehuhia te peita motuhake UV (paninga whakamaroke UV, waituhi whakamātao UV, me ētahi atu) e ngā taputapu ngaio, kātahi ka whakamarokehia e te mīhini whakamaroke UV hei hanga i tētahi paparanga tiaki ki runga i te mata. Ka taea te kī ko aua papa he papa UV.

Hei whakarāpopototanga, ko ngā papa katoa i pania ki te peita UV-āhua mā te whakamaroke i te mārama UV me ētahi atu maimoatanga, he papa UV.

He aha te hangarau UV?

He māmā noa iho, ko te hangarau UV he tukanga e pania tere ai te mata o te papa mā te maimoatanga whakamaroke UV.
Ka taea te wehewehe kia rua ngā wāhanga: te tukanga paparanga tiaki mārama UV me te tukanga tā waituhi UV.

1. Tukanga paparanga tiaki mārama UV

Mena ka whakamahia he paninga ārai UV, he wanihi mārama hoki, ka hangaia he paparanga tiaki mārama ki te mata o te papa.
Te rere o te tukanga:
Kōwhiringa rauemi → tapahi → horoi me te tango puehu → paninga paparanga hiri mārama i te raro o te papa → whakatika → e rua ngā paparanga o te paninga tuatahi, te whakamaroke UV, me te tukanga oro i te mata o te papa → e rua ngā paparanga o te paninga o runga, te whakamaroke UV, me te tukanga oro → tuatoru o ngā paparanga o te paninga o runga → whakamaroke UV → tirotiro me te whakaae → paninga kiriata tiaki.

2. Tukanga tā waituhi UV

Mena ka whakamahia he waituhi whakapūmau rama UV motuhake, he tukanga tā motuhake tēnei, he rite ki te tā i te tauira e hiahiatia ana ki runga i te papa mā te tā matihiko UV, kātahi ka pania he paparanga tiaki ki runga i te papa.
Te rere o te tukanga:
Hoahoa → Kōwhiringa rauemi → Tapahi → Horoi me te tango puehu → Paninga pereti rōra me te paninga UV mā → Tā waituhi waituhi taputapu motuhake UV → Paninga rōra me te paninga waituhi, whakamaroke UV, oro → Paninga rōra me te paninga waituhi, whakamaroke UV → Tirotiro me te whakaae → Takai kiriata tiaki.
