Ko ngā hua raupapa Nonylphenol Ethoxylate, me tō rātou pumau i roto i ngā taiao matū kino, ka mahi hei tāpiri mahi hei whakarei ake i te whai huatanga o te whakaora.
1. Kaikohi Kōwhiri me te Whakarei Huka i roto i ngā Tukanga Whakarewa Kohuke
I roto i ngā tukanga whakamānu mō ngā konganuku parahi i Chile, ngā konganuku tine i Bolivia, me ngā konganuku polymetallic i Brazil, me wehe pai ngā matūriki kohuke iti mai i te gangue (toka para).
●Ngā Wāhanga Matua o ngā Tauhohenga Whakarewa Matū:He maha ngā wā ka honoa ngā NPE ki ētahi atu kaikohi. Ka piri tō rātou hanganga ngota ki ngā mata o ngā kohuke whakarewa motuhake, ka whakarei ake i tō rātou ātete wai. I te wā kotahi, mā te whakahaere i te rahi me te pumau o ngā mirumiru, ka taea e rātou te piri atu ki ngā mirumiru me te mānu, kia pai ake ai te piri.te whakapai ake i te tere whakaora me te taumata kukū o te konganuku ūngaHe mea tino nui tēnei pānga whakarei ake mō te whakaū i ngā inenga whakaputa me te whakaiti i ngā utu whakarewa kotahi ina tukatukahia ngā konganuku he matatini te horapa, he rerekē rānei ngā taumata.
2. Kaiwhakarerekē Mahi i roto i ngā Wai Keri Hinu me te Whakakorenga Hinu Mata
I ngā mara hinu me te hau i Colombia, Argentina, me te Orinoco Belt o Venezuela, ka pāngia ngā mahi keri me te whakaputa e ngā wero mai i ngā hanganga pāmahana teitei me te tote teitei.
● Kaiwhakarewa me te Kaiwhakahinuhinu mō ngā Wai Keri Wai-Mahinga-Tiketike:I roto i ngā wai keri hinu, i ngā wai hanga rānei e whakamahia ana mō te keri i ngā hanganga tairongo pērā i te kirikiri, ka taea e ngā NPE te mahi hei emulsifier āwhina, hei āwhina i te whakau i te pūnaha wai keri. Ko te mea nui ake, ka taea e rātou te whakaiti i te ngaronga wai me te hanga i tētahi kiriata hinu whai hua i waenganui i te aho keri me te poka wai, hei whakaiti i ngā mōrearea o ngā paipa piri, me te whakarite kia...te haumaru me te whai huatanga o te keri mō ngā puna hohonu me ngā puna he hanganga uaua.
●Āwhina Whakaiti Matotoru mō te Whakaora me te Kawe Hinu Taumaha:Mō ngā hinu mata taumaha nui o Amerika ki te Tonga, he uaua te tango me te kawe i ngā paipa nā te matotoru teitei. Ka taea e ēnei hua te mahi hei whakaiti i te matotoru, hei wāhanga rānei i roto i ngā pūnaha whakaiti i te matotoru-whakarewa, ka whakarerekē i te āhua hononga hinu-wai hei hanga i ngā whakarewa hinu-i-roto-i-te-wai he iti te matotoru. Ka tino whakaitihia e tēnei te ātete rere,te whakarei ake i te āheinga whakaora ōhanga me te whai huatanga o te kawe paipa o te hinu taumaha.
