Naphthalene sulfonate formaldehyde Condensate(FDN) ndeye anionic surfactant ine mvura-phobic chimiro chinoumbwa nemethylene yakabatana ban ring uye mvura-philic chimiro ne sulfonic acid boka. Inoshandiswa zvakanyanya senge inoderedza mvura yekongiri, dhayi dispersant uye marasha mvura slurry dispersant nekuda kwekukura kwayo kwekugadzira maitiro uye yakanakisa dispersant performance. FDN inogadzirwa kubva kumaindasitiri naphthalene ne sulfonation, hydrolysis, condensation uye neutralization ine concentrated sulfuric acid.
Mumakore achangopfuura, nemutengo weindasitiri naphthalene, iyo inotora petroleum nemarasha seyakagadzirwa, ichikwira, inounza mutengo wakakwira mukugadzirwa kweFDN. Izvo zvakakosha zvehupfumi kuti uwedzere kuvandudza zvivakwa zveFDN nekugadziriswa kwemuviri nemakemikari kana kutsvaga zvitsva zvekutsiva maindasitiri naphthalene kugadzira FDN kudzikisa mutengo wekugadzira.CAS:36290-04-7
Naphthalene Sulfonate parizvino yakagadzirwa sezvo iyo FDN chigadzirwa Condensate ine panguva imwechete inopa ma molecular aggregation degree, yakafara molecular uremu kugovera uye humwe hunhu, kusangana nezvinodiwa zveinjiniya application, bepa iri, nenzira dzemuviri nzira dzeultrafiltration ichaita FDN zvinoenderana nemorekuru. huremu (inozivikanwawo sedhigirii repolymerization) yakaenderera mberi nechikamu, nehukuru spectrometry, elemental analyzer kufananidzwa kwechimiro chechimiro cheakasiyana molecular level yeFDN, uye akadzidza iyo FDN yakasiyana pane molecular level Kuti uwane kuita kuri nani kupararira kwe FDN giredhi.Sulfonated Naphthalene Condensate/ Sodium Munyu.
Kuti uongorore mutsauko weakasiyana mamolecular huremu zvikamu zveFDN mukuparadzira simende mashandiro ekushandisa, bepa rino rakaongorora maitiro ekushambadza kweFDN pamusoro pezvikamu zvesimende, zvinosanganisira electrokinetic kugona, adsorption kugona, adsorption layer ukobvu, uye nenzira yemamorekuru. kuzvibatanidza, akawana pesvedzero yehuremu hwemamorekuru, inorganic salts uye hydrogen bond force pane THE adsorption yeFDN.
