Te Whakataurite i te Āhuatanga Ātete Ngaronga Wai o te Cellulose Polyanionic i Hangaia e te Tukanga Paraoa me te Tukanga Parai

Ko te cellulose Polyanionic (PAC) he pūmua wairewa-wai i ahu mai i te cellulose, ā, e whakamahia whānuitia ana hei tāpiri whakahaere i te ngaronga wai i roto i ngā wai keri e whakamahia ana i roto i te tūhuratanga hinu me te hau. Ko ngā tikanga matua e rua mō te whakaputa PAC ko te tukanga paraoa me te tukanga paru. Anei te whakataurite i te āhuatanga ātete ngaronga wai o te PAC i hangaia e ēnei tukanga e rua:

1. Tukanga Paraoa:
   • Tikanga Whakaputa: I roto i te tukanga paraoa pokepoke, ka hangaia te PAC mā te tauhohe i te cellulose me te kawakore, pērā i te hauwai konutai, hei hanga i te paraoa pokepoke cellulose kawakore. Kātahi ka tauhohehia tēnei paraoa pokepoke ki te waikawa chloroacetic hei whakauru i ngā rōpū carboxymethyl ki runga i te tuara o te cellulose, ka hua ake ko te PAC.
   • Rahi Matūriki: Ko te PAC i hangaia e te tukanga paraoa pokepoke he nui ake te rahi o te matūriki, ā, kei roto pea he kohikohinga, he tāpeketanga rānei o ngā matūriki PAC.
   • Ātete ki te Ngaronga Wai: Ko te PAC i hangaia e te tukanga paraoa pokepoke he ātete pai ki te ngaronga wai i roto i ngā wai keri. Heoi, ko te rahi o te matūriki me te kitea pea o ngā mea whakahiato ka hua ake he puhoi ake te makuku me te horapa i roto i ngā wai keri wai, ka pā pea ki te mahi whakahaere ngaronga wai, inā koa i roto i ngā āhuatanga pāmahana teitei me te pēhanga teitei.
2. Tukanga Para:
   • Tikanga Whakaputa: I roto i te tukanga parai, ka whakamararatia tuatahitia te cellulose ki roto i te wai hei hanga i te parai, kātahi ka tauhohehia ki te hauwai konutai me te waikawa chloroacetic hei whakaputa i te PAC tika ki roto i te wairewa.
   • Rahi Matūriki: Ko te PAC i hangaia e te tukanga paraoa pokepoke he iti ake te rahi o te matūriki, ā, he ōrite ake te marara i roto i te wairewa ki te whakaritea ki te PAC i hangaia e te tukanga paraoa pokepoke.
   • Te Ātete ki te Ngaronga Wai: Ko te PAC i hangaia e te tukanga parapara he tino ātete ki te ngaronga wai i roto i ngā wai keri. Ko te rahi o te matūriki iti me te horapa ōrite ka hua ake he tere ake te makuku me te horapa i roto i ngā wai keri wai-pūtake, ka pai ake te whakahaere i te ngaronga wai, inā koa i roto i ngā āhuatanga keri uaua.

Ka taea e te PAC i hangaia e te tukanga paraoa pokepoke me te PAC i hangaia e te tukanga parai te ātete pai ki te ngaronga wai i roto i ngā wai keri. Heoi, tera pea ka tukuna e te PAC i hangaia e te tukanga parai ētahi painga, pēnei i te tere o te whakamakuku me te marara, ka hua ake ai te pai ake o te whakahaere i te ngaronga wai, inā koa i roto i ngā taiao keri pāmahana teitei me te pēhanga teitei. Hei whakamutunga, ko te kōwhiringa i waenga i ēnei tikanga whakaputa e rua ka whakawhirinaki pea ki ngā whakaritenga mahi motuhake, ngā whakaaro utu, me ētahi atu mea e pā ana ki te tono wai keri.
