FC-650S Ƙarin Kula da Asarar Ruwa
• FC-650S wani ƙarin sinadarin polymer ne na asarar ruwa ga siminti da ake amfani da shi a rijiyar mai kuma an samar da shi ta hanyar haɗakar sinadarai tare da AMPS/NN/HA a matsayin babban monomer tare da kyakkyawan juriya ga zafin jiki da gishiri, tare da haɗin gwiwa da sauran monomers masu hana gishiri. Kwayoyin halittar suna ɗauke da adadi mai yawa na ƙungiyoyi masu sha kamar - CONH2, - SO3H, - COOH, waɗanda ke taka muhimmiyar rawa wajen juriya ga gishiri, juriya ga zafin jiki, sha ruwa kyauta, rage asarar ruwa, da sauransu.
• FC-650S yana da sauƙin amfani kuma ana iya amfani da shi a cikin tsarin slurry iri-iri na siminti. Yana da kyakkyawan jituwa da sauran ƙari.
• FC-650S ya dace da yanayin zafi mai faɗi tare da juriya mai zafi har zuwa 230℃. Yana da ingantaccen aikin kwanciyar hankali a yanayin zafi mai zafi saboda shigar da sinadarin humic acid.
• Ana iya amfani da FC-650S shi kaɗai. Tasirin ya fi kyau idan aka yi amfani da shi tare da FC-631S/ FC-632S.
• Ya dace da shirya ruwan tsami/ruwan gishiri.
Filayen mai masu zafin jiki mai yawa suna fuskantar ƙalubale na musamman idan ana maganar simintin rijiyoyi. Ɗaya daga cikin waɗannan ƙalubalen shine batun asarar ruwa, wanda zai iya faruwa lokacin da matattarar laka da ke haƙa ramin ya mamaye samuwar kuma ya haifar da raguwar yawan ruwan.
