I roto i te ao hangarau teitei o te hanga taputapu tino tika, e whai tikanga ana ngā taipitopito katoa, kua piki haere te tono mō ngā taputapu tiaki motuhake pērā i ngā karapu nitrile Lijingjie. I roto i ngā āhuatanga whakahaere kounga, kua puta ake ngā whakaritenga ihirangi halogen hei mea nui, e kukume ana i te aro whānui mai i ngā kaihanga me ngā kaiwhakamahi mutunga.
Mai i te tirohanga ture me ngā paerewa, ahakoa kāore he paerewa motuhake e aro ana ki te nui o te halogen i roto i ngā karapu nitrile mō te hanga taputapu tika, ko ngā paerewa e tika ana mai i ngā ahumahi e pā ana he mahi ārahi. Kua whakaritea e te International Electrotechnical Commission (IEC) i roto i āna paerewa, mō ngā hua hiko me ngā hua hiko, ko te nui o te chlorine (Cl) me te bromine (Br) kaua e neke ake i te 900 wāhanga ia miriona (ppm) ia, ā, ko te nui o te ihirangi o ngā mea e rua kaua e neke ake i te 1500 ppm. I runga i ngā hononga tata i waenga i te hanga taputapu tika me te umanga hiko me te hiko, me ngā whakaritenga tino kaha ake mō te whakahaere halogen i roto i te hanga taputapu tika, me piri tonu ngā karapu nitrile Lijingjie ki ngā paerewa tino kaha.
Heoi, kei tua atu ngā paerewa tūturu o te umanga i ēnei whakaritenga taketake. I roto i ngā āhuatanga whakaputa tūturu i roto i te umanga hanga taputapu tino tika, he nui te tumanako kia iti iho te ihirangi halogen o ngā karapu nitrile i ngā rohe kua whakaritea e te IEC. I te nuinga o te wā, me iti iho te ihirangi chlorine i te 500 ppm, me raro iho hoki te ihirangi bromine i te 500 ppm, ā, ko ētahi tukanga hanga teitei e hiahia ana kia iti ake ngā taumata. Ko te whāinga o ēnei whakaritenga pakari ko te whakaiti i te pānga pea o ngā halogen ki ngā taputapu tino tika, kia mau ai te tino tika me te pono e mōhiotia ana ēnei taputapu.
Ko te take o ēnei whakaritenga mō te nui o te halogen i roto i ngā karapu nitrile kei roto i ngā tūponotanga ka pā mai i ngā halogen ki ngā taputapu tika. Ka taea e ngā halogen te waikura i ngā wāhanga o ngā taputapu tika, ka pā ki te mahi me te tika o ngā taputapu. Heoi anō, i te wā e whakamahia ana ēnei taputapu, ka tukuna pea e ngā halogen ngā hau kino, ka tū hei mōrearea ki te taiao me te hauora o te tangata. I te mea kei te whai tonu te hanga taputapu tika i ngā taumata teitei ake o te tika me te pono, kua noho te whakahaere pakari o te nui o te halogen i roto i ngā karapu nitrile hei wāhanga nui o te tukanga whakaputa, e whakaatu ana i te whakapau kaha o te umanga ki te kounga me te haumaru.
