Naphthalene sulfonate formaldehyde Condensate(FDN) he surfactant anionic me te hanganga wai-phobic i tito mai i te mowhiti aukati hono methylene me te hanganga wai-philic me te roopu waikawa sulfonic. Ka whakamahia whānuitia hei kaihoko whakaheke wai mo te raima, te waikano dispersant me te waro wai slurry dispersant no te mea o tona tukanga waihanga pakeke me te mahi dispersant pai. Kua whakaritea te FDN mai i te naphthalene ahumahi ma te sulfonation, hydrolysis, condensation me te whakakore ki te waikawa pungatara puri.
I nga tau tata nei, me te utu o te naphthalene ahumahi, e tango ana i te hinuhinu me te waro hei rauemi mata, ka piki ake, ka nui te utu mo te hanga FDN. He mea nui ohaoha ki te whakapai ake i nga ahuatanga o te FDN ma te whakarereke tinana me te matū, ki te kimi rauemi hou hei whakakapi i te naphthalene ahumahi hei whakahiato i te FDN hei whakaiti i te utu whakaputa.CAS:36290-04-7
Naphthalene Sulfonate Kei te synthesized tēnei wā rite te hua FDN Condensate kua i te wa ano whakarato tohu whakahiato rāpoi, tohatoha taimaha rāpoi whānui me ētahi atu āhuatanga, ki te whakatau i nga hiahia o te tono engineering, tenei pepa, i te tikanga o te tikanga tinana ultrafiltration ka FDN rite ki te rāpoi. Ko te taumaha (e mohiotia ana ano ko te tohu o te polymerization) kua mau ki te whakarōpūtanga, ma te papatipu matakite, te tohu kaitirotiro huānga o nga ahuatanga hanganga o nga taumata ngota rereke. o FDN, me te ako i nga momo FDN i runga i te taumata irapoi kia pai ake ai te mahi marara o te karaehe FDN.Naphthalene Condensate/ Tote Konutai.
I roto i te tikanga ki te tūhura i te rerekētanga o rerekē wāhanga taimaha rāpoi o FDN i roto i te mahi tono marara sima, ako tenei pepa i te whanonga adsorption o FDN i runga i te mata o matūriki sima, tae atu ki te electrokinetic kaha, kaha adsorption, adsorption matotoru paparanga, me te tikanga o te rāpoi. hui-whaiaro, i whiwhi i te awe o te taumaha ngota, tote pararopi me te kaha here hauwai ki TE adsorption o FDN. I tua atu.
