Amagama angukhiye: I-Poly dimethyl diallyl ammonium chloride, i-PDMDAAC, I-PDADMAC, I-PolyDADMAC
Ezweni elinemibala yemikhiqizo yamakhemikhali yansuku zonke, izithako eziningi, njengemicu engabonakali, ziluka ngokuthula isithombe esihle senqubo yethu yokunakekelwa kwesikhumba yansuku zonke.I-Poly dimethyl diallyl ammonium chloride (PDADMAC)iyisithako esinjalo—nakuba “singaveli” ngqo kumalebula ezimonyo, sihlanganiswe ngokujulile nemikhiqizo yokunakekelwa kwezinwele ngesimo se-polymer, siba nomthelela ekusithekeni kwezinwele nesikhumba esibushelelezi. Ngakho-ke, ingabe lesi sithako samakhemikhali siphephile ngempela ukuthi sihlangane naso? Impendulo itholakala ebudlelwaneni baso obuncane bokusebenzisana nezimonyo.
Isakhiwo samakhemikhali se-Poly dimethyl diallyl ammonium chloride sinikeza "ubunye" obuhlukile. Njenge-cationic polymer, ithwala ishaja enhle futhi ingamunca kalula imicu noma izinhlayiya ezishajelwe kabi. Embonini yezimonyo, lesi sici siguqulelwa emisebenzini esebenzayo: uma sengezwa ku-shampoo, siqeda ugesi omile okhiqizwa ukungqubuzana, senza izinwele zibe bushelelezi futhi zilawuleke esikhundleni sokuba ziqine; ku-shower gel, isebenza njengefilimu evikelayo engabonakali, inciphisa ukulahleka komswakama futhi ishiye isikhumba sizizwa sibushelelezi. Lo mphumela awusiwo umlingo, kodwa kunalokho uvela ekuguquguqukeni nasekuncibilikeni kwamanzi kwamaketanga ayo ama-molecule—isakazeka ngokushesha emanzini, yakha isisombululo esifanayo esimboza ngobumnene yonke imicu yezinwele noma isikhumba ngaphandle kokushiya umuzwa onamathelayo. Cabanga ngokukhanya okugelezayo ezinweleni zakho ngemva kokugeza; ikakhulukazi kungenxa yomsebenzi othule we-Poly dimethyl diallyl ammonium chloride.
Kodwa-ke, "ukuxhumana okuphephile"I-PolyDADMACakunamibandela. Ukuphathwa kwezithako ezimonyweni kufana nesenzo sokulinganisela esinembile, esidinga kokubili ukusebenza kahle kanye nokugwema ingozi.I-PolyDADMACngokwayo izinzile, ayizweli ezinguqukweni ze-pH, futhi ayishisi, inikeza isiqinisekiso esiyisisekelo sokusetshenziswa kwayo emikhiqizweni yamakhemikhali yansuku zonke. Kodwa isihluthulelo sisendabeni "yama-monomer ayo asele." Ngesikhathi sokwenziwa kwe-polymer, amanani amancane ama-monomer e-acrylamide angase angasabeli ngokugcwele, futhi i-acrylamide ngokwayo ingase icasule. Ngakho-ke, ukulawulwa okuqinile kwamanani asele kuyimfuneko yokuphepha. Isibonelo, kuma-shampoo noma okhilimu, inani le-Poly dimethyl diallyl ammonium chloride engeziwe lidinga ukulawulwa ngokunembile ukuqinisekisa ukuthi ukuhlushwa kwe-monomer kumkhiqizo kungaphansi komkhawulo ophephile, kugwenywe ukuthwala umthwalo esikhumbeni esibucayi. Lokhu kuphathwa okucophelelayo kuguqulaI-PolyDADMACkusukela ezintweni zokusetshenziswa zezimboni kuya esithakweni sokunakekelwa kwansuku zonke abathengi abangasisebenzisa ngokuthula kwengqondo.
Ngombono obanzi, "ukuphepha kokuxhumana"I-PolyDADMACkubonakala futhi ngobungane bayo bemvelo. Incibilika kalula emanzini, ayikhi amajeli, futhi imelana nama-ion e-chloride, okusho ukuthi akunakwenzeka ukuthi iqoqe noma ikhiphe izinto eziyingozi ekuhlanzweni kwamanzi amdaka noma ezindaweni zemvelo. Uma kuqhathaniswa nezinye izithasiselo zamakhemikhali,I-PolyDADMACinokubola okungcono, okunciphisa imiphumela yesikhathi eside emvelweni. Uma sikhuluma “ngokuxhumana ngqo,” asibhekiseli nje kuphela ekuthintaneni okufushane nesikhumba noma izinwele, kodwa futhi sihlanganisa yonke inkambo yayo yokuphila yemvelo—kusukela ekukhiqizweni kuya ekulahleni, ifilosofi yokuklamaI-PolyDADMACihlala ithambekele ebungozini obuphansi kanye nokuhambisana okuphezulu. Ekuphetheni,I-PolyDADMACAkuyona into evinjelwe "ukuxhumana ngqo," kodwa kunalokho, ngokusebenzisa indlela yesayensi kanye nemithetho eqinile, isibe ngumvikeli obalulekile nomnene wezimonyo. Njengomdwebi ongabonakali, isebenzisa amabhulashi ama-molecule ukuchaza isithombe esivumelanayo sobuhle nokuphepha. Ngesikhathi esizayo lapho ujabulela izinwele ezibushelelezi noma isikhumba esimanzi, khumbula umnikelo othule walokhu kuhlakanipha kwamakhemikhali—okwenza ukunakekelwa kwansuku zonke kube okusebenzayo nokuphephile.
