耐酸膠泥簡介:

  耐酸膠泥是由水玻璃和耐酸水泥調制而成的。***目前在建筑上常用的水玻璃是鈉玻璃,它的化學成份是硅酸(Na2O·nSiO2 ) ,分子式中的n 稱為水玻璃模數。模數=SiO2 含量Na2O 含量×Na2O 分子量SiO2 分子量模數越高,粘度越大,可溶性相應下降。平常使用的水玻璃是固體水玻璃的水溶液,波美度大致是24°~48°左右(比重112~115 左右) 。水玻璃具有較好的膠結性能,不燃燒,耐腐蝕,有較高的耐酸能力(除不能抵抗氫氟酸、硅氟酸、300 ℃以上的熱磷酸和***脂肪酸外) ,不耐堿。一般市場上出售的耐酸水泥是由磨細的石英砂或粉碎的天然輝緣巖和固化促進劑氟硅酸鈉(NaSiF6) 組成耐酸膠泥的硬化,首先是水玻璃與氟硅酸鈉發生水解,生成硅膠和Na (OH) 、HF、NaF ,然后HF 與Na (OH) 作用生成NaF 及水。
