Yashin yumbu mai Rufe Guduro
Bayani
Ana amfani da yashi yumbu a cikin yashi mai gyare-gyare da yashi mai mahimmanci don yin ƙirar harsashi da harsashi suna da kaddarorin juriya na zafin jiki, ƙarancin faɗaɗawa, rugujewa mai sauƙi, da ƙarancin fitar da iskar gas, wanda zai iya hana lahani na faɗaɗa a cikin simintin gyare-gyare.Don muryoyin da ke da siffofi na musamman, na iya magance matsalar cewa harbin yashi ba shi da sauƙi don haɗawa.Yashi ceramik da ake nema a cikin tsarin RCS.
Ana amfani da cikakken yashi yumbu don yin yashi mai rufi, kuma ana sake yin amfani da shi akai-akai bayan an sake gyarawa, wanda zai iya inganta inganci da samar da simintin gyare-gyare yadda ya kamata, rage yawan simintin simintin gyare-gyare da kuma farashin samar da kamfanoni, farashin amfani na dogon lokaci ya yi ƙasa da wancan. yashi silica.Saboda haka, a cikin 'yan shekarun nan, kusan dukkanin shuke-shuken yashi masu girma sun yi amfani da yashi yumbu a matsayin danyen yashi don samar da yashi mai rufi.
Siffofin
• Mafi girma refractoriness—- don jefa karafa tare da babban zub da zafin jiki (simintin karfe, alloyed simintin karfe, bakin karfe, da dai sauransu.)
• Ƙarfi mai ƙarfi da tauri—- don samar da ƙarin sarƙaƙƙiya mai rikitarwa tare da sassan bakin ciki.
Ƙarƙashin haɓakar zafi --don guje wa lahani na fadadawa.
• Haɓaka haɓaka mafi girma - don rage yawan zubar da yashi, don rage farashi.
Madalla da iya gudana --don yin sarƙaƙƙiya madauri.
• Ƙarƙashin amfani da ɗaure--ƙananan haɓakar iskar gas, ƙananan farashin masana'antu.
• Halayen sinadarai marasa ƙarfi --ana iya amfani da su a cikin kowane mashahurin gami, ya haɗa da ƙarfe na Manganese.
• Tsawon lokacin ajiya.
