xov xwm

Naphthalene sulfonate formaldehyde Condensate(FDN) yog ib qho anionic surfactant nrog dej-phobic qauv tsim los ntawm methylene txuas nrog txwv lub nplhaib thiab dej-philic qauv nrog sulfonic acid pawg. Nws yog dav siv los ua cov dej-txo tus neeg sawv cev rau pob zeb, dye dispersant thiab thee dej slurry dispersant vim nws cov txheej txheem ua kom muaj zog thiab kev ua haujlwm zoo heev. FDN yog npaj los ntawm kev lag luam naphthalene los ntawm sulfonation, hydrolysis, condensation thiab neutralization nrog concentrated sulfuric acid.

 

Nyob rau hauv xyoo tas los no, nrog rau tus nqi ntawm kev lag luam naphthalene, uas siv roj av thiab thee ua raw cov ntaub ntawv, nce, nws coj tus nqi siab rau kev tsim FDN. Nws yog qhov tseem ceeb ntawm kev lag luam txhawm rau txhim kho cov khoom ntawm FDN los ntawm kev hloov kho lub cev thiab tshuaj lom neeg los yog nrhiav cov ntaub ntawv tshiab los hloov cov khoom siv naphthalene los ua ke FDN kom txo cov nqi tsim khoom.CAS: 36290-04-7

Naphthalene Sulfonate yog tam sim no synthesized li FDN khoom Condensate muaj nyob rau tib lub sij hawm muab molecular aggregation degree, dav molecular hnyav tis thiab lwm yam ntxwv, kom tau raws li cov kev xav tau ntawm engineering daim ntawv thov, daim ntawv no, los ntawm lub cev txoj kev ultrafiltration yuav FDN raws li molecular qhov hnyav (tseem hu ua degree ntawm polymerization) tau nqa los ntawm kev faib tawm, los ntawm huab hwm coj spectrometry, elemental analyzer characterization ntawm tus qauv tus yam ntxwv ntawm qhov sib txawv molecular theem ntawm FDN, thiab kawm qhov sib txawv FDN ntawm molecular theem Yuav kom tau zoo dispersion kev kawm ntawm FDN qib.Sulfonated Naphthalene Condensate / Sodium ntsev.

 

Txhawm rau tshawb nrhiav qhov sib txawv ntawm qhov sib txawv ntawm qhov hnyav molecular ntawm FDN hauv cement dispersion daim ntawv thov kev ua tau zoo, daim ntawv no tau kawm txog tus cwj pwm adsorption ntawm FDN ntawm cov cement hais, nrog rau cov peev xwm electrokinetic, muaj peev xwm adsorption, adsorption txheej thickness, thiab los ntawm molecular. Kev sib sau ua tus kheej, tau txais kev cuam tshuam ntawm qhov hnyav molecular, inorganic ntsev thiab hydrogen bond quab yuam ntawm THE adsorption ntawm FDN. Ntxiv rau.
