Ko ngā painga o ngā mea whakaū tote mata ko:
1. He pai te pumau o te wera: Mā te kaha ki te chelating, ka taea te whakakapi i ngā ngota chlorine kāore i te pumau, te nui o te konganuku, me te kaha ki te mimiti i te HCl.
2. He pai rawa te ārai hiko: He iti te utu.
3. Ātete mārama pai rawa atu: He pai te whakahinuhinu o ētahi momo. Pērā i te mata dihydrogen phosphate, he pai te pumau, he pai te ārai i te mate pāwera me te ārai i te UV, ā, ka taea te whakarato i te pumau mārama pai me te pumau hāora wera o waho ki ngā kōtaha, tae atu ki te maeneene o te mata. Mā te whakakotahi me te TiO2 ka taea te whakaiti i te nui o ngā mimiti UV me ngā ārai i te mate pāwera e whakamahia ana, ā, ko Hechuan te pūnaha pumau e whakamahia whānuitia ana i roto i ngā kōtaha PVC i Haina.
4. He pai te tukatuka: He pai mō ngā momo tikanga tukatuka, ā, he mahi mā te tae.
Ko ngā ngoikoretanga o ngā mea whakaū tote mata ko:
1. Puehu nui: I te wā e whakamahia ana, he nui te puehu me ngā inenga maha, ka taea e ēnei te arahi ngāwari ki ngā hapa inenga me te pānga nui ki te kounga o ngā kōtaha, ka puta he parahanga. He paitini te manawa puehu ki te tinana tangata.
2. Ka piki ake te tūponotanga o te whakamahi i te kikorangi kahurangi.
3. Ka pirau te tote mata monomer me te kapia PVC i roto i te kōtaha ka puta ko te HCl me te PbCl2: ka puta tonu te maturuturunga o ngā katote konganuku. Ina heke rātou ki te mata o te kōtaha, i ngā wāhi he nui te parahanga whanariki, ka ngāwari te puta o te parahanga whanariki, ka puta te tae kore o te kōtaha. Nō reira, me tāpiri ngā kaihoko paninga katote cadmium mata, ngā kaihoko chelating, me ētahi atu ki te tauira tote mata. Ko tā rātou mahi he hanga i ngā matatini me ngā poke pēnei i ngā pūhaumāota i hangaia e te kōtaha, te aukati i te maturuturunga o ngā pūhaumāota konganuku kāore i te hototahi, me te aukati i te parahanga whanariki me te tae kore.
4. Kāore e tino marara: Kāore e tino marara ngā mea whakau tote mata.
5. Tino paitini: He tino paitini ngā mea whakaū tote mata.
6. Āhuatanga tae tīmatanga: He āhuatanga tae tīmatanga tō ngā whakaū tote mata, ā, he uaua ki te whiwhi hua mārama me ngā hua he kanapa ngā tae.
7. Te korenga o te hinu whakahinuhinu: Kāore he hinu whakahinuhinu o ngā mea whakaū tote mata, ā, he ngāwari ki te poke i te whanariki.
Hei whakarāpopototanga, he painga motuhake ngā mea whakaū tote mata i roto i te tukatuka kirihou, engari he ngoikoretanga nui anō hoki kāore e taea te wareware. I roto i ngā mahi whaihua, me whai whakaaro whānui ki ēnei āhuatanga me te mahi i ngā mahi e tika ana hei whakakore i ō rātou ngoikoretanga.
