May 05, 2022
Sodium naphthalene sulfonate formaldehyde dispersant
Khoom npe: Dispersant MF
Lub npe Askiv: Naphthalenesulfonic acid, polymer nrog formaldehyde, sodium ntsev
CAS Nr: 9084-06-4
Khoom: Dispersant MF yog xim av hmoov, yooj yim soluble nyob rau hauv dej, yooj yim nqus dej noo, tsis-flammable, muaj zoo heev diffusivity thiab thermal stability, tsis permeability thiab foaming, acid thiab alkali tsis kam, nyuaj dej thiab inorganic ntsev, thiab yog resistant rau paj rwb. thiab linen. Nws tsis muaj affinity rau lwm cov fibers; nws muaj affinity rau cov protein thiab polyamide fibers; Nws tuaj yeem siv nrog anionic thiab non-ionic surfactants, tab sis tsis tuaj yeem tov nrog cationic dyes lossis surfactants; nws muaj peev xwm tiv thaiv disperse vat dye hais los ntawm thermal agglomeration Zoo dua li diffused NNO. Dispersant MF yog ib qho anionic surfactant.
Kev npaj: coj cov feem ntawm cov thee tar nrog boiling ntau ntawm 235-250 degree (muaj 2-methylnaphthalene ua lub ntsiab tivthaiv) raws li raw khoom, tau txais methylnaphthalenesulfonic acid los ntawm sulfonation, thiab ces condense nws nrog formaldehyde.
Qhov Performance index zoo: Cov khoom npe Performance index Dispersion zog (rau cov qauv khoom), feem pua ntau dua los yog sib npaug rau 96 Heat resistance stability (dispersion xiav 79) 130 degree Qib 4 ~ 5 Sulfate cov ntsiab lus feem pua tsawg dua los yog sib npaug rau 5 PH tus nqi (1 feem pua aqueous tov) 7 ~ 9 Insoluble Impurity cov ntsiab lus hauv dej feem pua Tsawg dua lossis sib npaug rau 0.05 Cov ntsiab lus ntawm calcium thiab magnesium ions, feem pua Less dua los yog sib npaug rau 0.4
