I-Naphthalene sulfonate formaldehyde Condensate(i-FDN) i-anionic surfactant enesakhiwo se-water-phobic esakhiwe yi-methylene exhunywe indandatho yokuvinjelwa kanye nesakhiwo samanzi-philic esineqembu le-sulfonic acid. Isetshenziswa kabanzi njenge-ejenti yokunciphisa amanzi kakhonkolo, i-disperant yodayi kanye ne-slurry dispersant yamanzi amalahle ngenxa yenqubo yayo yokwenziwa evuthiwe kanye nokusebenza okuhle kakhulu kwe-disperant. I-FDN ilungiswa kusuka ku-naphthalene yezimboni nge-sulfonation, hydrolysis, condensation kanye ne-neutralization nge-concentrated sulfuric acid.
Eminyakeni yamuva, ngentengo ye-naphthalene yezimboni, ethatha i-petroleum namalahle njengezinto zokusetshenziswa, ikhuphuka, iletha izindleko eziphezulu ekukhiqizeni i-FDN. Kubaluleke kakhulu kwezomnotho ukuqhubeka nokuthuthukisa izakhiwo ze-FDN ngokuguqulwa ngokomzimba namakhemikhali noma ukuthola izinto ezintsha zokufaka esikhundleni se-naphthalene yezimboni ukuze kuhlanganiswe i-FDN ukuze kwehliswe izindleko zokukhiqiza.I-CAS:36290-04-7
I-Naphthalene Sulfonate okwamanje ihlanganiswe njengoba umkhiqizo we-FDN Condensate unesikhathi esifanayo ukuhlinzeka ngeziqu ze-molecular aggregation, ukusatshalaliswa kwesisindo samangqamuzana abanzi nezinye izici, ukuze kuhlangatshezwane nezidingo zokusetshenziswa kobunjiniyela, leli phepha, ngokusebenzisa izindlela zomzimba ultrafiltration ngeke FDN ngokusho kwamangqamuzana. isisindo (esaziwa nangokuthi idigri ye-polymerization) siqhubekile nokuhlukaniswa, nge-mass spectrometry, ukuchazwa kohlaziyo okuyisisekelo kwezici zesakhiwo sezinga elihlukile lamangqamuzana e-FDN, futhi safunda i-FDN ehlukile ezingeni lamangqamuzana Ukuze uthole ukusebenza okungcono kokuhlakazeka Ibanga le-FDN.Sulfonated Naphthalene Condensate/ Sodium Salt.
Ukuze uhlole umehluko wezingxenye ezihlukene zesisindo samangqamuzana e-FDN ekusebenzeni kwesicelo sokuhlakazwa kukasimende, leli phepha lifunde ukuziphatha kwe-adsorption ye-FDN ebusweni bezinhlayiya zikasimende, okuhlanganisa amandla e-electrokinetic, umthamo we-adsorption, ukujiya kongqimba lwe-adsorption, futhi kusetshenziswa i-molecule. ukuzihlanganisa, kutholwe ithonya lesisindo samangqamuzana, usawoti we-inorganic kanye namandla e-hydrogen bond ku-adsorption ye-FDN. Ngaphezu kwalokho.
