Rorohiko Whakamahana UV | Inga Kuaea & Tika i te Taiao

Kua puta mai ngā papanga whakawera UV hei otinga matua i te āpure o te tiaki me te whakarei ake i te mata, e tuku ana i ngā painga maha puta noa i ngā ahumahi rerekē. Kua hangaia ēnei papanga ki ngā raukaha, ngā monomers, ngā pūkaha whakaahua, me ngā tāpiritanga e taea ana te whakaora i te UV, ā, ko tā rātou tikanga motuhake e whakaora ana i te rama ultraviolet e wehe ana i ngā papanga tuku iho. Ko te kaupapa matua o ngā paninga whakawera UV kei roto i te tukanga polymerization whakaoho-whakaahua. I te wā e pā ana ki te rama UV, ka hopu ngā pūkaha whakaahua i roto i te papanga i te pūngao, ka whakaputa i ngā matū koreutu. Na ka urupare ēnei irirangi koreutu ki ngā monomers me ngā oligomers i roto i te paninga, ka meinga kia whakawhiti-hono, ka hanga i tētahi kiriata mārō, pūmau i runga i te mata o te paparanga. Ka tere te mahi o tēnei whakawera, i roto i ngā hēkona, e kore ai e hiahiatia he wā roa ki te whakamaroke e pā ana ki ngā paninga noa. Ko tētahi o ngā painga matua o ngā paninga whakawera UV ko tō rātou pakeke pai me te ātete ki te kōhao. Ina whakarewahia, ka hanga te papanga i tētahi papanga pakeke, roa, e kaha ana ki te tu atu i ngā taumahatanga mīhini, pēnei i te kiri, te kōpeke, me te kakau. Ma tenei ka pai ai te whakamahi i a raatau mo nga tono e tino nui ana te tiaki o te mata, penei i te umanga motuka mo te paninga o nga motuka, i te umanga taonga hei tiaki i nga papa rakau, me te umanga papa mo te whakanui ake i te roa o nga papa. Ko ngā paninga whakawera UV he tino kaha hoki te aukati i ngā matū. Ka taea e rātau te aukati i ngā mate o ngā matū maha, tae atu ki ngā waikawa, ngā waikawa, ngā waikura, me ngā waikura horoi. Mā tēnei āhuatanga e pai ai te whakamahi i ngā taiao ahumahi e pā ana ki ngā mata e whakakikoruatia ana e ngā matū pakeke. Hei tauira, i roto i te ahumahi kai me te inu, ka taea te whakamahi i ngā papanga UV-whakarewa i runga i ngā rauemi tākai hei tiaki i ngā hua mai i te poke matū, me te pupuri i te tika o te tākai. Ko tētahi atu painga ko to rātau tino māramatanga me te ahuareka. Ka taea e ngā papanga whakawera UV te whakarato i tētahi mutunga maeneene, parakore e whakanui ana i te ahua o te mata o te mata. Ka taea hoki te whakarite kia rerekē ngā kakano o te mata, pēnei i te matte, i te satin rānei, kia tutuki ai ngā whakaritenga hoahoa motuhake. I roto i te ahumahi whakakakahu whakapaipai, ka whakamahia whānuitia ngā whakakakahu UV-whakarewa hei hanga i ngā whakaotinga ataahua ki runga i ngā momo hua, mai i ngā taonga hokohoko ki ngā āhuatanga hoahoanga. I tua atu, he iti rawa te taiao o ngā paninga whakawera UV. Na te mea ka whakaorangia e rātau mā tētahi urupare matū e tīmata ana e te rama UV, ā, kāore e whakawhirinaki ki te whakarewa o te waikura, ka whakaitihia e rātau te tuku o ngā pūhui rauropi rerehua (VOCs). Mā tēnei e noho tonu ai rātou i te whakataurite ki ngā paninga tuku iho e hāngai ana i te waikura, e whai wāhi ana ki tētahi tukanga whakaputa māmā ake, ki tētahi taiao hauora ake.
