Sodium Naphthalene Sulfonate Formaldehyde Condensate

Sodium naphthalene sulfonate formaldehyde condensate
Cov ntawv luv luv] NSF Condensate [Cov yam ntxwv] Cov khoom no yog ib qho tshwj xeeb anionic surfactant, feem ntau yog siv los ua dispersant lossis ua cov dej ua haujlwm siab rau kev tsim kho.
-naphthalenesulfonate sodium formaldehyde condensate yog naphthalene-raws li anionic surfactant ua los ntawm refined naphthalene los yog muaj naphthalene los ntawm sulfonation, hydrolysis, condensation thiab lwm yam kauj ruam. Nws muaj kev ntub dej zoo, nkag mus, emulsifying, dispersing, foaming thiab lwm yam khoom, dav siv los ua xim dispersant, dye dispersant, pigment dispersant, emulsion polymerization dispersant, precipitant, anti-adhesive agent thiab cement dej txo tus neeg sawv cev thiab lwm yam.
Daim ntawv no sib piv qhov zoo ntawm -naphthalene sulfonate sodium formaldehyde condensate uas tsim los ntawm lub tuam txhab domestic raws li ib tug dispersant rau neoprene emulsion polymerization nrog cov khoom zoo sib xws nyob rau hauv lub tebchaws United States, thiab pom tau hais tias qhov zoo ntawm cov khoom no mas muaj ob yam nram qab no deficiency: ib sab tes, xim ntawm -naphthalene sulfonate sodium formaldehyde condensate yog tsaus dua; Ntawm qhov tod tes, thaum -naphthalene sulfonate sodium formaldehyde condensate yog siv los ua ib qho dispersant rau neoprene emulsion polymerization, kev ruaj ntseg ntawm chloroprene roj hmab kuj tsawg. Qhov txawv. Cov ntsiab lus tshawb fawb tshwj xeeb ntawm qhov kev tshawb fawb no yog raws li hauv qab no: ① Kev tshuaj ntsuam xyuas qhia tau tias yog vim li cas -naphthalenesulfonate sodium formaldehyde condensate muaj xim tsaus dua li nws cov khoom lag luam yog vim li cas -naphthalenesulfonate sodium formaldehyde condensate yog tsim thaum naphthalene sulfonation -naphthalenesulfonic acid. cov -naphthalenesulfonic acid formaldehyde condensate tau los ntawm condensing cov khoom nrog formaldehyde ua rau -naphthalenesulfonic acid sodium formaldehyde condensate darker dua nws cov khoom txheem.
