He rerekētanga nui i waenga i ngā kaiwhakaū tote mata me ngā kaiwhakaū konutea konutea i ngā āhuatanga maha, tae atu ki te hanganga, te mahi, te atawhai taiao, te mahi tukatuka, me ngā mara e tika ana.
Te Hanganga me te Mahi
Ko ngā mea whakaū tote mata e wehea ana kia rua ngā wāhanga matua: ngā monomer me ngā mea whakahiato. Ko ngā hua e tohu ana i ngā tote mata monomeric ko te mata trisulfate me te mata dibasic phosphate, he iti te utu me te ngāwari o te whakarerekētanga tauira, engari he ngāwari ki te parahanga sulfide me ngā raruraru tae. Ka whakapai ake ngā mea whakaū tote mata whakahiato i te marara me te pumau wera mā te whakaranu i ngā wāhanga maha mā te hangarau tauhohenga tahi, engari kei roto tonu ngā wāhanga mata. Ko ngā mea whakaū konupūmā konutea he mea hanga mai i ngā tote konutea, ngā tote konutea, ngā hinu whakahinuhinu, me ngā antioxidants, ā, he āhuatanga kore paitini me te tino whai hua. Ehara i te mea ka taea anake te whakakapi i ngā tote cadmium mata paitini me ngā mea whakaū organotin, engari he pai hoki te pumau wera, te pumau whakaahua, me te mārama.
He tino pai te mahi tukatuka o ngā whakaū konupūmā konutea, ā, he rite tonu te pumau o te pāmahana ki tērā o ngā whakaū tote mata.
Te atawhai i te taiao
Kei roto i ngā whakaū tote mata ngā huānga mata, e tūpono ana ki te taiao me te hauora o te tangata, nō reira kei te whakawhāitihia haeretia te whakamahinga. Kāore he huānga konganuku taumaha i roto i ngā whakaū konupūmā konutea, ā, e tutuki ana i ngā paerewa taiao pērā i ngā ture EU ROHS me REACH, e pai ake ai te taiao.
Te mahi tukatuka me ngā āpure e tika ana
He pai te mahi a ngā whakaū tote mata i roto i te tukatuka PVC, he tino pai te pumau o te wera me te ārai hiko, he pai mō ngā momo hua PVC. Heoi, nā ngā take taiao, he iti noa iho te whakamahinga. He whānuitia te whakamahinga o ngā whakaū konupūmā konutea i roto i ngā mara pēnei i te takai kai, ngā taputapu hauora, me ngā waea me ngā taura nā te mea kāore e paitini.
