                                    粉煤灰蒸壓磚與粉煤灰加氣混凝土砌塊在工藝制作和物理結構上有什么差異,如何辨別二者的區別,小編的為您整理了相關的信息?! ∫?、本質相同:  從生產原理的本質上,二者是相同的,即均是利zhi用粉煤灰含的dao硅質材料和石灰(鈣質材料),在高壓釜中高溫高壓條件下,直接合成硅酸鈣,產生強度?! 《?、區別:  1、強度:  粉煤灰壓蒸磚是壓制成型,密實度高,容重和強度均比較高。粉煤灰加氣混凝土的容重和強度相對要低很多?! ?、保溫隔熱性:  粉煤灰壓蒸磚保溫隔熱性能相對低,粉煤灰加氣混凝土保溫隔熱性能好,配料中,摻入發泡劑——鋁f粉,在進入高壓釜前,有一個靜停發泡階段,鋁v粉會與石灰(氫氧化鈣)反應產生氫氣,形成大量獨立、均勻分布的氣泡,發泡結束后,加氣混凝土要切割成為砌塊或板,然后進入高壓釜進行熱合反應,屬于無機輕質保溫材料?! ?、用處:  粉煤灰壓蒸磚一般用于砌筑承重墻,粉煤灰加氣混凝土一般用于非承重墻?! ∫陨暇褪嵌邊^別相關信息,了解才會更加的進行使用,粉煤灰加氣混凝土砌塊才會,希望小編的信息會幫助到您,如有其它業務問題,歡迎撥打電話咨詢。 產品展示 產品展示 產品展示 產品展示 產品展示 產品展示 產品展示 產品展示
