Naphthalene sulfonate formaldehyde condensate(FDN) ndi anionic surfactant yokhala ndi madzi-phobic kapangidwe kamene kamapangidwa ndi methylene yolumikizidwa ndi ban mphete ndi mawonekedwe amadzi-philic okhala ndi gulu la sulfonic acid. Amagwiritsidwa ntchito kwambiri ngati njira yochepetsera madzi konkriti, dispersant utoto ndi malasha madzi slurry dispersant chifukwa cha kukhwima kwake kupanga ndi ntchito yabwino dispersant. FDN imakonzedwa kuchokera ku mafakitale naphthalene ndi sulfonation, hydrolysis, condensation ndi neutralization ndi sulfuric acid.
M'zaka zaposachedwa, ndi mtengo wa mafakitale a naphthalene, omwe amatenga mafuta ndi malasha monga zopangira, akukwera, amabweretsa mtengo wokwera pakupanga FDN. Ndizofunika kwambiri pazachuma kupititsa patsogolo zinthu za FDN mwa kusintha kwakuthupi ndi mankhwala kapena kupeza zida zatsopano zolowa m'malo mwa naphthalene yamakampani kuti apange FDN kuti achepetse mtengo wopanga.CAS: 36290-04-7
Naphthalene Sulfonate panopa apanga monga FDN mankhwala Condensate ali pa nthawi yomweyo kupereka maselo aggregation digiri, yotakata maselo kulemera kugawa ndi makhalidwe ena, kukwaniritsa zosowa za uinjiniya ntchito, pepala ili, mwa njira thupi ultrafiltration adzakhala FDN malinga ndi maselo. kulemera (komwe kumadziwikanso kuti digiri ya polymerization) kwapitilira magawo, ndi misa spectrometry, elemental analyzer mawonekedwe a mawonekedwe a mamolekyu osiyanasiyana a FDN, ndikuphunzira ma FDN osiyanasiyana pamlingo wa mamolekyulu Kuti athe kupeza bwino kubalalitsidwa kwa kalasi ya FDN.Sulfonated Naphthalene Condensate / Sodium Salt.
Kuti muwone kusiyana kwa magawo osiyanasiyana olemera a mamolekyu a FDN pakugwira ntchito kwa simenti yobalalika, pepalali lidasanthula machitidwe a adsorption a FDN pamwamba pa tinthu tating'ono ta simenti, kuphatikiza kuthekera kwa electrokinetic, mphamvu ya adsorption, makulidwe a adsorption layer, komanso pogwiritsa ntchito ma molekyulu. kudzipanga tokha, kudatengera kulemera kwa maselo, mchere wa inorganic ndi hydrogen bond force pa kutsatsa kwa FDN. Kuphatikiza apo.
