Kupumatua: Poly dimethyl diallyl ammonium chloride, PDMDAAC, PDADMAC, PolyDADMAC
I te ao kanapa o ngā hua matū o ia rā, he maha ngā kai, pērā i ngā miro kāore e kitea, e whatu mārire ana i te pikitia ataahua o tā tātou mahi tiaki kiri o ia rā.Te konupūmā haukinia polydimethyl diallyl (PDADMAC)he matū pēnei—ahakoa kāore e "puta" tika mai i ngā tapanga whakapaipai, he mea whakauru hohonu ki roto i ngā hua tiaki makawe i roto i te āhua polymer, ka noho hei mea whai wāhi ki muri i ngā mahi hei whakangawari i te makawe me te kiri. Nō reira, he tino haumaru tēnei matū ki te pā atu? Kei roto i tōna whanaungatanga ngawari ki ngā whakapaipai te whakautu.
Nā te hanganga matū o te Poly dimethyl diallyl ammonium chloride ka homai he "hononga" ahurei. Hei pūmua cationic, he utu pai tōna, ā, ka taea te mimiti ngāwari i ngā muka, i ngā matūriki rānei kua utu kino. I roto i te umanga whakapaipai, ka whakamaoritia tēnei āhuatanga ki ngā mahi whai hua: ina tāpirihia ki te hopi horoi makawe, ka whakakore i te hiko pateko i puta mai i te waku, ka maeneene, ka taea te whakahaere i te makawe, kaua e pōturi; i roto i te wai kaukau, ka mahi ia pērā i te kiriata tiaki e kore e kitea, ka whakaiti i te ngaronga o te makuku, ā, ka waiho te kiri kia maeneene. Ehara tēnei pānga i te makutu, engari i ahu mai i te ngāwari me te wairewa wai o ōna mekameka ngota - ka tere te horapa i roto i te wai, ka hanga he otinga ōrite e pania mārie ana ia whenu makawe, ia kiri rānei, me te kore e waiho he ahua piri. Whakaarohia te kanapa rere i runga i ō makawe i muri i te kaukau; ko te nuinga o te wā nā te mahi puku o te Poly dimethyl diallyl ammonium chloride.
Heoi, ko te "whakapā haumaru" oPolyDADMACehara i te mea mutunga kore. He rite te whakahaere kai i roto i ngā mea whakapaipai ki tētahi mahi taurite tika, e hiahia ana kia whai huatanga me te karo i ngā mōrearea.PolyDADMACHe pumau tonu, kāore e pāngia e ngā huringa pH, ā, kāore e mura, e whakarato ana i te taurangi taketake mō tōna whakamahinga i roto i ngā hua matū o ia rā. Engari ko te mea nui kei roto i te take o ōna "monomers toenga." I te wā o te polymerization, kāore pea e tino tauhohe ngā rahinga iti o ngā monomers acrylamide, ā, he mea whakapataritari pea te acrylamide. Nō reira, ko te whakahaere pakari i ngā rahinga toenga he mea nui mō te haumaru. Hei tauira, i roto i ngā shampoos, i ngā kirīmi rānei, me whakahaere tika te nui o te Poly dimethyl diallyl ammonium chloride i tāpirihia kia tika ai te kukū o te monomer i roto i te hua kei raro iho i te paepae haumaru, kia kore ai e taumaha te kiri tairongo. Ka huri tēnei whakahaere tupato.PolyDADMACmai i te rauemi mata ahumahi hei kai tiaki o ia rā, ka taea e ngā kaihoko te whakamahi me te rangimarie o te hinengaro.
Mai i tētahi tirohanga whānui, ko te "haumarutanga whakapā" oPolyDADMACe whakaatahia ana hoki i roto i tōna āhua pai mō te taiao. He ngāwari te wairewa ki te wai, kāore e hanga he kirikiri, ā, he ātete ki ngā iona hauhāora, ko te tikanga kāore pea e kohia, e tukuna rānei ngā matū kino i roto i te maimoatanga wai para, i ngā taiao tūturu rānei. Ki te whakatauritea ki ētahi tāpiringa matū,PolyDADMAChe pai ake te pirau o te kiri, ka whakaiti i ngā pānga taiao mō te wā roa. Ina kōrero tātou mō te "pānga tika," ehara i te mea ko te pānga poto ki te kiri, ki te makawe rānei te mea e kōrero ana tātou, engari e kapi ana hoki i tōna huringa ora katoa - mai i te whakaputanga ki te whakakorenga, ko te rapunga whakaaro hoahoa oPolyDADMACe anga tonu ana ki te iti o te mōrearea me te hototahi teitei. Hei whakamutunga,PolyDADMACEhara i te mea tapu te "pā atu tika," engari, nā te hanga pūtaiao me te ture tino pakari, kua noho hei kaitiaki tino nui, ngawari hoki i roto i ngā whakapaipai. Pērā i te kaitoi e kore e kitea, ka whakamahia e ia ngā whiu paraihe ngota hei whakaahua i tētahi pikitia maeneene o te ataahua me te haumaru. A te wā e whai ake nei ka pai koe ki te makawe maeneene, ki te kiri makuku rānei, kia mahara ki te takoha puku o tēnei whakaaro matū—kia whai hua ai, kia haumaru ai hoki te tiaki i ia rā.
