Amagama angundoqo: I-Poly dimethyl diallyl ammonium chloride, i-PDMDAAC, I-PDADMAC, I-PolyDADMAC
Kwihlabathi elinemibala yeemveliso zeekhemikhali zemihla ngemihla, izithako ezininzi, njengemisonto engabonakaliyo, ziluka ngokuthula umfanekiso omhle wenkqubo yethu yokhathalelo lolusu yemihla ngemihla.I-poly dimethyl diallyl ammonium chloride (PDADMAC)yinto enjalo—nangona “ingabonakali” ngokuthe ngqo kwiileyibhile zezithambiso, idityaniswe nzulu kwiimveliso zokhathalelo lweenwele ngendlela yepolymer, ibe negalelo elingasemva kwemifanekiso kwiinwele nolusu olugudileyo. Ngoko ke, ngaba le nto yekhemikhali ikhuselekile ngokwenene ukuba ingadibana nayo? Impendulo ikubudlelwane bayo obuncinci bokubambisana nezinto zokuthambisa.
Ulwakhiwo lweekhemikhali lwePoly dimethyl diallyl ammonium chloride luyinika "ubunye" obukhethekileyo. Njenge-cationic polymer, ithwala itshaja entle kwaye inokufunxa ngokulula imicu okanye amasuntswana atshajwe kakubi. Kwishishini lezinto zokuthambisa, olu phawu luguqulelwa kwimisebenzi esebenzayo: xa longezwa kwi-shampoo, linciphisa umbane ongashukumiyo oveliswa kukungqubana, lenza iinwele zibe bushelelezi kwaye zilawuleke endaweni yokuba ziqine; kwi-shower gel, isebenza njengefilimu ekhuselayo engabonakaliyo, inciphisa ukulahleka komswakama kwaye ishiye ulusu luziva luthambile. Esi siphumo asingomlingo, kodwa sivela kukuguquguquka kunye nokunyibilika kwamanzi kwimixokelelwane yayo yeemolekyuli—isasazeka ngokukhawuleza emanzini, yenze isisombululo esifanayo esigquma ngobunono yonke imicu yeenwele okanye ulusu ngaphandle kokushiya imvakalelo enamathelayo. Khawuthelekelele ukukhanya okuhambayo kwiinwele zakho emva kokuhlamba; kungenxa yomsebenzi ongashukumiyo wePoly dimethyl diallyl ammonium chloride.
Nangona kunjalo, "unxibelelwano olukhuselekileyo"I-PolyDADMACayixhomekekanga kwimiqathango. Ulawulo lwezithako kwizithambiso lufana nesenzo sokulinganisela esichanekileyo, esifuna ukusebenza kakuhle kunye nokuphepha umngcipheko.I-PolyDADMACngokwayo izinzile, ayikhathali kutshintsho lwe-pH, kwaye ayitshi, inika isiqinisekiso esisisiseko sokusetyenziswa kwayo kwiimveliso zeekhemikhali zemihla ngemihla. Kodwa eyona nto iphambili ikumbandela we "residual monomers" zayo. Ngexesha le-polymerization, ubungakanani obuncinci bee-acrylamide monomers busenokungasabeli ngokupheleleyo, kwaye i-acrylamide ngokwayo inokucaphukisa. Ke ngoko, ulawulo oluqinileyo lwemilinganiselo eseleyo luyimfuneko yokhuseleko. Umzekelo, kwiishampu okanye kwiikhrimu, ubungakanani be-Poly dimethyl diallyl ammonium chloride eyongeziweyo kufuneka bulawulwe ngokuchanekileyo ukuqinisekisa ukuba uxinzelelo lwe-monomer kwimveliso lungaphantsi komda okhuselekileyo, kuthintelwe umthwalo wolusu olubuthathaka. Olu lawulo lucokisekileyo luguqulaI-PolyDADMACukusuka kwizinto eziluhlaza zoshishino ukuya kwisithako sokhathalelo lwemihla ngemihla abathengi abanokusebenzisa ngoxolo lwengqondo.
Ngokwembono ebanzi, "ukhuseleko lokunxibelelana"I-PolyDADMACikwabonakala ngokuba nobuhlobo nokusingqongileyo. Inyibilika lula emanzini, ayivelisi iijeli, kwaye iyamelana nee-ion ze-chloride, nto leyo ethetha ukuba akunakwenzeka ukuba iqokelele okanye ikhuphe izinto eziyingozi kunyango lwamanzi amdaka okanye kwiindawo zendalo. Xa kuthelekiswa nezinye izongezo zeekhemikhali,I-PolyDADMACinokonakala ngcono, nto leyo enciphisa iimpembelelo zexesha elide kwindalo. Xa sithetha “ngokunxibelelana ngqo,” asibhekiseli nje kuphela ekudibaneni okufutshane nolusu okanye iinwele, kodwa sikwaquka yonke impembelelo yayo kwindalo—ukusuka kwimveliso ukuya ekulahleni, ifilosofi yoyiloI-PolyDADMACIhlala ithe tyekele ekubeni nobungozi obuphantsi kunye nokuhambelana okuphezulu. Ukuqukumbela,I-PolyDADMACAyilonto ingafanelekanga "yokunxibelelana ngqo," kodwa endaweni yoko, ngokusebenzisa indlela yesayensi kunye nemithetho engqongqo, iye yaba ngumkhuseli obalulekileyo nonobunono kwizithambiso. Njengomzobi ongabonakaliyo, isebenzisa iibrashi zemolekyuli ukuchaza umfanekiso ohambelanayo wobuhle kunye nokhuseleko. Ngexesha elizayo xa ukonwabela iinwele ezigudileyo okanye ulusu olumanzi, khumbula igalelo elithuleyo lolu bulumko beekhemikhali—olwenza ukhathalelo lwemihla ngemihla lube lusebenza kwaye lukhuselekile.
