He aha te Tānga UV

Ko te tānga UV he momo tānga matihiko e whakamahi ana i ngā rama ultra-violet hei whakamaroke, hei whakaora rānei i te waituhi i te wā e tāia ana. I te tohatohanga o te waituhi e te pūreretā ki runga i te mata o tētahi rauemi (e kiia ana ko te "papa"), ka whai tata mai ngā rama UV kua hangaia mō te motuhake, ka whakaora – ka whakamaroke rānei – i te waituhi. I whakawhanakehia tuatahitia mō te whakamaroke tere i ngā paninga whao gel i te wā e mahi ana i ngā manicure, ka tere te horapa o ngā tono rama ultraviolet ki ngā mākete ahumahi me ngā mākete arumoni. Nā te mea ka whakaora tonu ngā rama UV i tētahi waituhi tā, kāore ngā ira o te waituhi mākū e horapa atu i muri i te tānga, ka hua ake he taipitopito pai ake.
I te tekau tau atu i 1960, i whakamahia tuatahitia te whakamaroke UV ki ngā mahi ahumahi, he mea tino pai mō te whakamaroke i te mata o te rakau. I muri mai, i hangaia e te US te whakamahinga UV mō te tā papatahi, ā, i tino whai hua. Kātahi ka horapa haeretia tēnei hangarau ki te UK me ētahi atu whenua. Kua whakamahia kētia te hangarau whakamaroke UV ki ngā momo tikanga tā, ā, kua urutau ki ngā momo momo katoa, pērā i te poraka whakawātea, te Flexo, te pereti tuhi, te pereti tā mata, ā, ka whakakapia e ia ngā tikanga tā tawhito, ka penapena rauemi tangata me ngā rauemi, kātahi ka hangaia he uara nui.

Ko ētahi o ngā hua o te whakamahi i te tānga UV ko:
He pai te tae o te pikitia i tāia e te Pūreretā UV, he kanapa rawa, he pai te tirohanga, ā, he hou ake te āhua i tērā i te tikanga tā tawhito.
Ka taea e te tikanga tā UV te tā ki runga i te mata o ngā momo rauemi katoa mā te mangumangu UV, ā, ka whānui ake te whānuitanga o ngā tono a te mīhini tā UV. Inaianei kua whakamahia kētia ki te pepa, ki te papa pepa, ki te sima kirihou, ki te whatunga rori, ki te PVC, ki te PE me ērā atu. He pai te wāhi mākete, ā, kei te whānui haere tonu te whānuitanga o ngā hoko me ngā mara tono.
Ka taea e te pūreretā UV te whakamaroke me te whakamaroke i te hoahoa tā. Ka tino whakapai ake i te pai o te mahi, ka whakanui ake i te whakaputanga, ka whakapoto i te wā mahi. Ka taea hoki e koe te whakamahi i te mangumangu, ka penapena utu.
Ka tere te totoka me te maroke o te pūreretā UV i muri i te otinga o te hoahoa tā. Kāore e memeha te tae, ā, kāore e hiahiatia he paura rehu me ētahi atu mea whakamaroke, ka taea te tiaki i te hoahoa mai i te kino.
Kāore he mea poke i te wā e hangaia ana te Pūreretā UV, he pai mō te taiao, ā, he iti noa iho, he kore rānei he pānga o te mangumangu UV ki te tinana.
