Kua noho ngā taura muka whatu hei poutokomanawa mō ngā pūnaha whakawhitiwhiti kōrero o ēnei rā. He mea nui te mahi me te pakari o ēnei taura ki te pono me te kounga o ngā whatunga whakawhitiwhiti kōrero. He mea nui ngā rauemi e whakamahia ana i roto i ēnei taura kia taea ai e rātou te tu atu ki ngā taiao uaua, kia pumau ai hoki te tuku kōrero mō ngā wā roa.
Ko tētahi o ngā rauemi kua arohia whānuitia i roto i te umanga ko te Polybutylene Terephthalate (PBT). He tino pai ngā āhuatanga ā-mīhini, ā-hiko, ā-wera o ngā rauemi PBT, ā, he pai mō te whakamahi i roto i ngā taura muka whatu. Ko tētahi o ngā painga matua o ngā rauemi PBT ko te iti o te mimiti makuku, ā, he pānga nui tēnei ki te pumau me te roa o ngā taura.
Ka taea e te mimiti makuku i roto i ngā taura te arahi ki ngā momo raruraru, tae atu ki te whakaiti i te tohu, te taumaha o te taura, me te heke o te kaha kume. Ka taea hoki e te makuku te waikura me te kino ki te taura i roto i te wā. Heoi, he iti te tere mimiti wai o ngā rauemi PBT, e āwhina ana ki te whakaiti i ēnei raruraru me te whakapai ake i te pumau me te roa o ngā taura.
Kua whakaatuhia e ngā rangahau ka taea e ngā rauemi PBT te mimiti i te iti rawa o te 0.1% o te makuku i raro i ngā āhuatanga noa. Mā tēnei tere mimiti makuku iti ka āwhina i te pupuri i ngā āhuatanga ā-pūkaha me te hiko o te taura i roto i te wā, ka ārai i te pirau, i te kino rānei o te taura. Hei tāpiri, he tino ātete ngā rauemi PBT ki ngā matū, ki te hihi UV, me ngā pāmahana tino kino, ka whakarei ake i te roa me te mahi o te taura.
Hei whakamutunga, ko te iti o te mimiti makuku o ngā rauemi PBT he mea pai mō te whakamahi i roto i ngā taura muka whatu. Mā te whakarato i te pumau me te roa o te ora, ka taea e ngā rauemi PBT te āwhina ki te whakarite i te mahi pono o ngā whatunga whakawhitiwhiti kōrero. I te mea kei te tipu haere tonu te tono mō ngā pūnaha whakawhitiwhiti kōrero kounga teitei, e matapaetia ana ka piki ake te whakamahinga o ngā rauemi PBT, ka waiho hei rauemi whai hua mō te umanga taura.
