Ko te ngongo hihi ultraviolet (ngongo UV) he mea whakau mārama e taea ai te ngongo i te wāhanga hihi ultraviolet o te rā me ngā pūtake mārama hihiko me te kore e whakarerekē i a ia anō. Ko te nuinga o te ngongo hihi ultraviolet he paura tioata ma, he pai te pumau o te wera, he pai te pumau o te matū, kāore he tae, kāore he paitini, kāore he kakara, e whakamahia whānuitia ana i roto i ngā polymer (kirihou, me ētahi atu), ngā paninga me ētahi atu.
Ko te nuinga o ngā tae, inā koa ko ngā tae kore-waro, ka taea te whakaū i te māramatanga ina whakamahia takitahi i roto i ngā hua kirihou. Mō ngā hua kirihou tae mō te whakamahinga roa o waho, kāore e taea te whakapai ake i te pumau o te māramatanga o te hua e te tae anake. Mā te whakamahi i te whakaū māramatanga anake ka taea te aukati, te whakaroa rānei i te tere koroheketanga o te māramatanga o ngā hua kirihou tae mō te wā roa. Ka whakapai ake i te pumau o te māramatanga o ngā hua kirihou tae. Ko te whakaū māramatanga amine ārai (HALS) he akomanga o ngā matū amine waro me te pānga aukati steric. Nā āna mahi ki te pirau i te hydroperoxide, te tinei i te hāora radical, te hopu i ngā radical kore utu, me te hangarua i ngā rōpū whai hua, ko te HALS te whakaū māramatanga kirihou me te kaha teitei ki te ārai i te whakaahua-pakeketanga me te nui rawa atu i te kāinga me tāwāhi. E whakaatu ana ngā raraunga ka taea e te whakaū māramatanga tika, te pūnaha whakakotahitanga tika rānei o te antioxidant me te whakaū māramatanga te whakapai ake i te pumau o te māramatanga me te hāora o ngā hua kirihou tae o waho i ngā wā maha. Mō ngā hua kirihou kua taehia ki ngā tae photoactive me ngā tae photosensitive (pērā i te kōwhai cadmium, te rutile kāore i te matua, me ētahi atu), me te whakaaro ki te pānga photoaging catalytic o te tae, me whakanui ake te nui o te whakaū mārama.
Ko ngā mea mimiti UV ka taea te whakarōpū i runga i te hanganga matū, te wāhanga mahi me te whakamahinga, e whakaahuatia ana i raro nei:
1. Te whakarōpūtanga e ai ki te hanganga matū: ka taea te wehewehe i ngā ngongo hihi ultraviolet ki ngā ngongo hihi ultraviolet waro me ngā ngongo hihi ultraviolet kore-waro. Ko ngā ngongo hihi ultraviolet waro ko te nuinga o ngā benzoates, benzotriazole, cyanoacrylate, me ētahi atu, ko ngā ngongo hihi ultraviolet kore-waro ko te nuinga o te konutea waikura, te waikura rino, te hauhā titanium me ētahi atu.
2. Te whakarōpūtanga i runga i te momo mahi: ka taea te wehewehe i te momo mimiti hihi ultraviolet ki te momo parepare me te momo mimiti. Ka taea e ngā momo mimiti hihi UV parepare te whakaata i te mārama UV, ā, ka ārai i te urunga ki roto i te tinana, ko ngā momo mimiti hihi UV ka taea te mimiti i te mārama UV me te huri hei wera, hei mārama kitea rānei.
3. Whakarōpūtanga e ai ki te whakamahinga: ka taea te wehewehe i te mimiti hihi ultraviolet ki te kounga whakapaipai, te kounga kai, te kounga rongoā, me ētahi atu. Ko ngā mimiti hihi UV kounga whakapaipai e whakamahia ana i roto i te pare rā, i ngā hua tiaki kiri me ētahi atu mea whakapaipai, ko ngā mimiti hihi UV kounga kai e whakamahia ana i roto i ngā rauemi takai kai, ā, ko ngā mimiti hihi UV kounga rongoā e whakamahia ana i roto i ngā rongoā.
