Ka tutuki i ngā karapu nitrile kore-halogen a Lijiejing te whakahaere pakari i te ihirangi halogen mā te pūnaha porowhita-toru o te "mana whiriwhiri rauemi pūtake, mana whakahaere tika o te tukanga whakaputa, me te whakamātautau tika o te hua kua oti." Ko ngā mahi motuhake ko: Te Kōwhiringa Rauemi Pūtake: Te whakakore i te whakaurunga halogen i te wāhanga rauemi mata mā te whiriwhiri i te nitrile latex iti-halogen/kore-halogen, me te whakarite kia ≤150ppm te ihirangi halogen ā-roto. Te Whakahaere Pūmau i te Kōwhiringa Tāpiri: Ko ngā tāpiri katoa, tae atu ki ngā kaihoko whakamomona me ngā whakateretere, ka tīpakohia mai i ngā momo kore-halogen, hoa-taiao, pērā i ngā pūnaha whakamomona kore-halogen. Ahakoa he nui ake ngā utu o ēnei tāpiri hoa-taiao, ka ārai i te whakaurunga halogen ki te pūtake. Te Whakahaere Tika o te Whakaputa: Te arotau i ngā tukanga whakamomona puta noa i te whakaputanga hei whakaiti i ngā toenga halogen. Te whakahaere tika i te pāmahana, te pēhanga, me te roa o te tauhohenga i te wā o te whakamomona whakamomona. Te whakamahi i ngā tikanga whakamomona kua whakaritea hei whakaiti i ngā hua taha o te hauwai halogen - ahakoa te whakanui ake i te whakapaunga pūngao, ka tino whakaitihia te ihirangi halogen. Te Horoi me te Whakamaarama Whakapai Ake: Ka uru te rapa i muri i te whakapūhuitanga ki tētahi tukanga whakakotahi o te 3-5 horoinga wai maha-wāhanga me te wehenga porowhita. Ka tangohia e te wai whakakore iona ngā monomer halogen me ngā tāpiringa toenga, he nui atu i te paerewa horoi 1-2 mō ngā karapu noa. Ka whakamahia te hangarau whakamaroke pāmahana iti (≤90°C) te whakamaroke korehau rānei hei ārai i te pirau rauemi me te hanganga matū halogen i puta mai i ngā pāmahana teitei, kia mau ai ngā uara halogen. Te whakahaere i ngā tawhā horoi chlorine tika: Ko te ihirangi chlorine i roto i te wai horoi he mea herea noa ki te 350-600 ppm, me te roa o te horoinga e whakahaeretia ana i te 0.3-1 meneti, e whakataurite ana i te whai huatanga o te horoi me te mōrearea halogen toenga. Te Whakamātautau Tika: Te Tukunga Whakatutukitanga Puranga-i-te-Puranga Ka whakatū i tētahi pūnaha whakamātautau tino tika me ngā chromatograph ion, ngā ine fluorescence hihi-X, me ētahi atu taputapu. Ka whakahaerehia he tātaritanga tauanga o te ihirangi chlorine (Cl) me te bromine (Br) i roto i ia puranga, ka tutuki i ngā rohe kitenga i te taumata ppm, tae atu ki te tautuhi tohu taumata ppb. Mā te piripono ki ngā paerewa o te ao ka tutuki ngā whakaritenga a te IEC me te RoHS: ko te ihirangi o te chlorine (Cl) me te bromine (Br) kei raro iho i te 900 ppm ia ia, ko te ihirangi halogen katoa kei raro iho i te 1500 ppm, ā, ko ētahi hua ka eke ki ngā taumata halogen katoa he iti iho i te 50 ppm, iti iho rānei.
