Naphthalene sulfonate formaldehyde Condensate(FDN) ke anionic surfactant e nang le sebopeho sa phobic sa metsi se entsoeng ka lesale la thibelo ea methylene le sebopeho sa metsi-philic se nang le sehlopha sa sulfonic acid. E sebelisoa haholo e le moemeli oa ho fokotsa metsi bakeng sa konkreite, dispersant ea dae le dispersant ea metsi a mashala ka lebaka la ts'ebetso ea eona e tsoetseng pele ea maiketsetso le ts'ebetso e ntle ea ho qhala. FDN e lokiselitsoe ho tloha naphthalene ea indasteri ka sulfation, hydrolysis, condensation le neutralization ka concentrated sulfuric acid.
Lilemong tsa morao tjena, ka theko ea naphthalene ea indasteri, e nkang peterole le mashala e le thepa e tala, e ntseng e phahama, e tlisa litšenyehelo tse phahameng ho hlahisa FDN. Ho bohlokoa moruong ho tsoela pele ho ntlafatsa thepa ea FDN ka phetoho ea 'mele le ea lik'hemik'hale kapa ho fumana lisebelisoa tse ncha ho nka sebaka sa naphthalene ea indasteri ho kopanya FDN ho fokotsa litšenyehelo tsa tlhahiso.CAS: 36290-04-7
Naphthalene Sulfonate hajoale e entsoe ha sehlahisoa sa FDN Condensate ka nako e ts'oanang se fana ka degree ea aggregation ea molek'hule, kabo e pharaletseng ea boima ba limolek'hule le litšobotsi tse ling, ho fihlela litlhoko tsa ts'ebeliso ea boenjiniere, pampiri ena, ka mekhoa ea 'mele ea ultrafiltration e tla FDN ho latela limolek'hule. boima (hape bo tsejoa e le degree of polymerization) bo 'nile ba tsoela pele ka lihlopha, ka mass spectrometry, elemental analyzer characterization ea litšobotsi tsa sebopeho sa maemo a fapaneng a limolek'hule tsa FDN, mme a ithuta FDN e fapaneng maemong a limolek'hule E le ho fumana ts'ebetso e ntle ea phallo ea sehlopha sa FDN.Sulfonated Naphthalene Condensate/ Letsoai la sodium.
Bakeng sa ho hlahloba phapang ea likarolo tse fapaneng tsa boima ba limolek'hule tsa FDN ts'ebetsong ea ts'ebeliso ea samente, pampiri ena e ithutile boitšoaro ba adsorption ea FDN holim'a likaroloana tsa samente, ho kenyeletsoa bokhoni ba electrokinetic, matla a adsorption, botenya ba adsorption layer, le ka limolek'hule. ho ipokella, ho ile ha fumana tšusumetso ea boima ba limolek'hule, matsoai a inorganic le hydrogen bond force ho THE adsorption of FDN.
