Naphthalene sulfonate formaldehyde Condensate(FDN) waa surfactant anionic leh qaab-dhismeed biyo-phobic ka kooban methylene ku xiran giraanta ganaax iyo qaab-dhismeedka biyaha-filic oo leh kooxda sulfonic acid. Waxaa si weyn loo isticmaalaa sida wakiilka biyaha-dhimista ee shubka, dheeha dheeha iyo firidhsan biyaha dhuxusha sababtoo ah habka synthetic ee baaluq iyo wax qabad aad u fiican. FDN waxaa laga diyaariyaa naphthalene warshadaha iyadoo la adeegsanayo sulfonation, hydrolysis, uumi iyo dhexdhexaadin leh sulfuric acid.
Sanadihii la soo dhaafay, iyadoo qiimaha naphthalene ee warshadaha, oo qaada batroolka iyo dhuxusha sida alaabta ceeriin, kor u kaca, waxay keenaysaa qiimo sare wax soo saarka FDN. Waa muhiimad dhaqaale in la sii wanaajiyo sifooyinka FDN iyadoo la bedelayo jireed iyo kiimiko ama in la helo qalab cusub oo lagu beddelo naphthalene warshadaha si loo soo saaro FDN si loo yareeyo kharashka wax soo saarka.CAS:36290-04-7
Naphthalene Sulfonate hadda waa la farsameeyey sida FDN wax soo saarka Condensate ayaa isla mar ahaantaana bixiya shahaadada isugeynta kelli, qaybinta miisaanka kelli ballaaran iyo sifooyin kale, si loo daboolo baahida codsiga injineernimada, warqadan, iyada oo loo marayo hababka jireed ultrafiltration doonaa FDN sida waafaqsan molecular. Miisaanka (sidoo kale loo yaqaan heerka polymerization) ayaa qaaday kala soocida, iyadoo loo eegayo spectrometry mass, falanqeeye elemental sifada qaabdhismeedka heerka kala duwan ee unugyada FDN, oo uu bartay FDN kala duwan ee heerka molecular si loo helo waxqabadka fidinta ee darajada FDN.Sulfonated Naphthalene Condensate/ Sodium Salt.
Si loo sahamiyo kala duwanaanshaha qaybaha kala duwan ee miisaanka kelli ee FDN ee waxqabadka codsiga sibidhka, warqadani waxay daraasad ku samaysay habdhaqanka adsorption ee FDN ee dusha sare ee walxaha sibidhka, oo ay ku jiraan awoodda korantada, awoodda adsorption, dhumucda lakabka adsorption, iyo iyada oo la adeegsanayo molecular. is-urursi, la helay saamaynta miisaanka molecular, cusbada aan organic ahayn iyo xoogga bond hydrogen on THE adsorption of FDN. Intaa waxaa dheer.
