耐酸胶泥是由水玻璃和耐酸粉料调制而成，它的主要化合物是硅酸，水玻璃具有较好的粘性，耐火、耐腐蚀能力强，耐酸但是不耐碱。耐酸胶泥施工过程中要注意保持干燥，它的固化过程是使二氧化硅脱水，施工中要特别注意防水、防潮、保持干燥等，这是决定施工是否成功的关键因素。

Acid resistant cement is made of sodium silicate and acid resistant powder. Its main compound is silicic acid, water glass has good viscosity, fire resistance and corrosion resistance, acid resistance, but not alkali resistance. During the construction of acid resistant cement, we should pay attention to keeping it dry. Its curing process is to dehydrate silica. During construction, we should pay special attention to waterproofing, moisture-proof and keeping dry. This is the key factor to decide whether the construction is successful.

烟囱是农村人家和很多工厂都有的产物，烟囱的筒壁内衬要使用耐酸胶泥，耐酸胶泥一般用轻质骨料、粉料、粘合剂与添加剂组成，粘合剂的主要成分是水玻璃，耐酸胶泥也可以作为隔热材料使用，它不另外设置隔热层，轻质骨料结构的孔隙率大，表面比较粗糙，混合后流动性差，对运输和存储的要求比较高。耐酸胶泥的体积和密度小、凝固快，使用温度高，抗压强度随着温度和酸度的提高而提高，导热系数小。

The chimney is rural people and many factories have some products, the cylinder wall lining chimney to use acid resistant cement, acid resistant cement with light aggregate, powder, binder and additive, the main component of the binder is acid resistant cement water glass, can also be used as insulation materials used, it is also the heat insulation layer of lightweight aggregate structure high porosity, rough surface, mixed to poor mobility, transport and storage requirements are relatively high. The acid resistant mud has small volume and density, fast solidification and high temperature. The compressive strength increases with the increase of temperature and acidity, and the coefficient of thermal conductivity is small.
