Ko ngā mata polyurethane noa ko ngā mata maina polyurethane me ngā mata whakamaroke polyurethane. E whakamahia ana ngā pereti mata polyurethane i roto i te mahi whakarewa (te rino, te kōhatu, te fluorite, te para o te oumu whakamatao, te coke me ētahi atu rauemi mata), ngā konganuku kore-ferrous, te waro, ngā matū, ngā rauemi hanga me te miihini hiko wai, te tukatuka para whakakoi, te keri pari me ētahi atu ahumahi. Te keri, te tātari, te whakarōpū me ētahi atu ahumahi.
Ko ngā mahi matua me ngā āhuatanga o te pereti tātari polyurethane ko:
1. He pai te ātete ki te pakū, ko tōna ātete ki te pakū e 3 ki te 5 ngā wā i tō ngā pereti tātari maitai, ā, e 5 ngā wā i tō ngā pereti tātari rapa noa.
2. He iti te mahi tiaki, he ngāwari te pakaru o te mata polyurethane, ā, he roa te ora o te mahi, nō reira ka taea te whakaiti i te nui o te tiaki me te ngaronga o te tiaki.
3. He iti te utu katoa. Ahakoa he kotahi te roa o te mata polyurethane o te rahi (rohe) i te mata kowiri tira (tata ki te 2 ngā wā), ko te roa o te ora o te mata polyurethane he 3 ki te 5 ngā wā i tērā o te mata kowiri tira, ā, he maha ngā wā tiaki me ngā wā whakakapinga. Nō reira, kāore i te nui te utu katoa, ā, he tino whai hua hoki.
4. He ātete pai ki te makuku, ka taea te mahi i raro i te wai hei reo, ā, i raro i te wai, te hinu me ētahi atu reo, ka whakaitihia te tauwehenga waku i waenga i te polyurethane me te rauemi, ka pai ake te urunga o te mata, ka whakapai ake i te pai o te mata, ā, ka taea te karo i ngā matūriki mākū. I te wa ano, nā te iti o te tauwehenga waku, ka whakaitihia te kakahu, ka roa ake te ora ratonga.
5. Ātete ki te waikura, ā, kāore e mura.
6. Nā te hoahoa whaitake o ngā kōhao tātari me te tukanga hanga ahurei o te pereti tātari, e kore ngā matūriki o te rahi rawa e ārai i ngā kōhao tātari.
7. He pai te mahi mimiti wiri, he kaha ki te whakaiti haruru, ka taea te whakaiti i te haruru, ā, ka kore e ngawari te pakaru o te rauemi mata i te wā e wiri ana.
8. Nā ngā āhuatanga wiri tuarua o te polyurethane, ka taea e te mata polyurethane te horoi i a ia anō, nō reira he teitei te whai huatanga o te tirotiro.
9. Te penapena pūngao me te whakaiti i te whakapaunga. He iti te taumaha motuhake o te polyurethane, ā, he mama ake i ngā mata rino o te rahi ōrite, nā reira ka whakaitihia te kawenga o te mīhini mata, ka penapena i te whakapaunga hiko, ā, ka roa ake te ora o te mīhini mata.
