II ngā tau tata nei, kua piki haere te aro ki te paninga UV puta noa i ngā ahumahi mai i te takai ki ngā hikohiko. E mōhiotia ana mō tōna kaha ki te whakarato i ngā whakaoti kanapa me te tiaki roa, e kiia ana he hangarau whai hua, he hangarau hoki e pai ana ki te taiao. Engari me pēhea te mahi?
Ko te paninga UV e whakawhirinaki ana ki tētahi tukanga e kiia nei ko te whakamaroke ultraviolet. He ranunga wai te paninga kei roto ko ngā oligomer, ngā monomer, me ngā photo-initiators. Kia pania ki tētahi mata, ka whakaatuhia te rauemi paninga ki te hihi ultraviolet. Ka mimitihia e ngā photo-initiators te kaha o te mārama, ka puta he momo tauhohe pēnei i ngā rauropi kore utu. Ka tere te whakaoho a ēnei ngota tauhohe i te polymerization, ka huri i te paninga wai hei kiriata totoka mārō, honohono i roto i ngā hēkona.
E whakanui ana ngā tohunga ahumahi, ehara i te mea ka whakaiti noa i te wā whakaputa tēnei tukanga whakamaroke tere, engari ka whakakorea hoki te hiahia mō te whakamaroke i runga i te wera, ka nui ake te penapena hiko mō te paninga UV. He tino ātete te kiriata whakamaroke ki te rakuraku, he roa te mau o ngā matū, ā, he ātaahua ake te tirohanga, e whakamārama ana i tōna whakamahinga whānui i roto i te whakaotinga taonga, ngā rauemi tā, ngā roto o ngā motuka, tae atu ki ngā taputapu hiko hangarau teitei.
Ko tētahi atu painga matua, e ai ki ngā kaitātari ahumahi, ko te āhua taiao o ngā paninga UV. He rerekē ki ngā paninga whakarewa tuku iho e tuku ana i ngā matū waro mimiti (VOC), he maha ngā hanganga UV kua hangaia kia tata kore he VOC. Mā tēnei ka whakaitihia te parahanga o te hau me ngā tūponotanga o te wāhi mahi, kia rite ki ngā paerewa taiao o te ao.
Kei te whānui haere hoki ngā tono o te paninga UV i ngā whanaketanga o te ao. Ko ngā mahi auaha hou ko ngā paninga UV ngāwari mō ngā kiriata takai, ngā paninga tino ātete mō ngā taputapu hauora, tae atu ki ngā whakatakotoranga biocompatible mō te whakamahi i roto i te hauora. Kei te whakamātautau hoki ngā kairangahau i ngā pūnaha UV ranu e whakakotahi ana i te whakaora pūngao me te nanotechnology hei whakapai ake i te mahi ārai me te whakaroa i te roa o te ora o te hua.
I te mea ka noho ko te oranga tonutanga hei kaupapa matua i roto i te mahi hanga, e matapaetia ana e ngā tohunga ka nui haere te hiranga o te hangarau paninga UV. I te mea kei te piki haere te hiahia o te ao mō ngā rauemi e pai ana ki te taiao me te mahi teitei, e tūmanakohia ana ka whakatakotohia e ngā paninga UV he paearu hou mō te whai huatanga, te pakari, me te hoahoa, ka huri i ngā paerewa puta noa i ngā ahumahi maha.
