Te Whakataurite i ngā Rerekētanga Matua i waenga i ngā Whakapūmau Konupūmā Konutea PVC me ngā Whakapūmau Tote Mata:
1, Te atawhai i te taiao me te paitini
1. Kaiwhakaū konupūmā konutea
Kāore he konganuku taumaha pērā i te mata me te cadmium, e tutuki ana i ngā paerewa taiao a te EU RoHS/REACH;
Kua whai tiwhikete FDA, he pai mō ngā mara e pā ana ki te haumaru pērā i te takai kai me ngā taputapu hauora.
2. Whakapūmau tote mata
Nā te mea kei roto te mata whakarewa taumaha, ka puta te parahanga puehu paitini i te wā tukatuka, ā, ka pā kino ki te hauora o te tangata mēnā ka roa te wā e whakamahia ana;
Ka ngāwari te whakapoke i te oneone me te wai e ngā hua kua whakarērea.
2, Tikanga pumau wera
1. Kaiwhakaū konupūmā konutea
Mā te tikanga whakatika paparanga rua: ka whakakapia e te hopi konutea ngā ngota haurehu kore pumau, ka whakahoutia e te hopi konutea te hopi konutea hei whakaroa i te wā pumau;
Me whakamahi ngā matū honohono pēnei i te β – diketone me te hydrotalcite hei whakarei ake i te pumau (me te tāpiri i te nui o te 0.3% -2%)
2. Whakapūmau tote mata
Te hanga tika i tētahi matatini me ngā ngota PVC, e ārai pai ana i te tauhohenga mekameka tango HCl;
Ka taea e te wāhanga kotahi te whakatutuki i te pumau wera mō te wā roa, me te kore e hiahiatia he pūnaha mahi tahi matatini.
3, Te mahi tukatuka
| Ngā tūemi whakataurite | Whakapūmau konupūmā konutea | 铅盐稳定剂 |
| Te whakahinuhinu; | Me whakahaere tika te ōwehenga o te hinu whakahinuhinu (ka ngawari te maturuturu ki te nui rawa) | Kei roto ngā āhuatanga whakahinuhinu me te matapihi tukatuka whānui |
| whakahaere tae; | He kikorangi te tae o te hua, ā, me whakatika mā te tāpiri i te toner. | He pumau te tae me te iti o ngā rerekētanga i waenga i ngā puranga |
| Te rere o te rewa; | Whakaitihia te pāmahana kirihou mā te 5-10 ℃ | He iti noa te pānga ki te matotoru o te rewa |
4, Ngā herenga o te horopaki tono
1. Kaiwhakaū konupūmā konutea
Me tāpiri te hypophosphite (0.5%) ki ngā hua mārama hei whakapai ake i te māramatanga;
Ka pāngia ngā pūnaha whakakī nui (konupūmā kāponāte>30phr) e te huka.
2. Whakapūmau tote mata
◉ E pā ana ki ngā hua kore-mārama anake (pērā i ngā paipa me ngā kōtaha);
Nā te taiao kei roto i te whanariki i te raki, ka ngāwari te huri o te mata o ngā hua hei whanariki, hei mangu hoki.
5. Ngā rerekētanga ōhanga
E 40% te iti iho o te mātotoru o te whakapūmau konutea konutea, ka taea te whakanui ake i te nui o te whakakī i tāpirihia me te whakaiti i ngā utu;
He iti iho te utu mō ngā mea whakau tote mata, engari me pikau he utu tāpiri mō te maimoatanga konganuku taumaha;
Mā te whakataurite i ngā taha maha, ka kitea he tino painga tō ngā kaiwhakaū konupūmā konutea i roto i te urutau ki te taiao, engari kei te mau tonu te uara tono motuhake o ngā kaiwhakaū tote mata i roto i te manawanui tukatuka me te whakahaere utu.
