naphthalene superplasticizer wani chemically hada ba iska entrained superplasticizer tare da karfi watsawa sakamako a kan siminti barbashi da kyau amfani da shirya super kwarara kankare., sit-in-situ kankare da precast membobi tare da farkon ƙarfi da babban ƙarfin buƙatun. Yana iya haɓaka kaddarorin simintin gabaɗaya kuma ana amfani da shi sosai akan manyan hanyoyi, gadoji, madatsun ruwa, harbors, tunnels, wutar lantarki, kiyaye ruwa da kuma masana'antu da gine-gine.
The naphthalene superplasticizer shine samfurin natsuwa na sodium naphthalene sulfonate formaldehyde condensate (FDN-B). Yana da barga na zahiri da sinadarai, kamar ƙananan kumfa, yawan rage yawan ruwa, m farkon ƙarfin haɓakawa da ƙarfin daidaitawa ga siminti. Ana iya amfani da shi a daban-daban kankare tare da ƙananan sashi da sauƙin amfani.
Idan aka kwatanta da polycarboxylate ethers, poly-naphthalene sulfonate (PNS) da kuma lignosulfonate (LS) anionic polyelectrolytes masu narkewa da ruwa waɗanda za'a iya ƙarawa zuwa sabon grout na tushen siminti don ƙara yawan ruwa.. Hakanan za su iya hana haɓakar ƙwayoyin siminti da haɓaka hydration na C4A3S zuwa ettringite a cikin sabbin turmi..
Wannan binciken shine don bincika tasirin naphthalene da PCE tushen superplasticizers akan saita lokaci, ruwa, da ƙarfin matsa lamba na C4A3S CSA turmi wanda aka kunna ta nau'ikan nau'ikan mai kunnawa NaOH. Bugu da kari, ilimin halittar jiki, adadin, da microstructure na kayayyakin hydration an yi nazari ta XRD, thermogravimetric (TG), da kuma bincikar microscope na lantarki (WANE), bi da bi.
Sakamakon ya nuna cewa superplasticizer na tushen naphthalene ya tsawaita saitin farko da saitin ƙarshe na manna CSA tare da allurai daban-daban.. Superplasticizer na tushen naphthalene galibi an haɗa shi a saman simintin siminti kuma yana fitar da ruwa kyauta., don haka an tsawaita lokacin saitin a ƙarƙashin repulsion electrostatic. Superplasticizer na tushen naphthalene kuma ya haɓaka hydration na C4A3S mai ɗauke da ettringite zuwa matakin mafi girma., wanda ya kara karfin turmi na CSA.
