水玻璃有较好的耐蚀性,但因耐水、耐稀酸及抗渗性较差,使其使用范围受到限制。我们于1970年初施工了一部分水玻璃糠醇砂浆地面,用掺入糠醇树脂的办法,提高其耐水、耐稀酸性能,并掺入石棉绒,以减少其收缩裂缝。已正式应用于有有机酸、有机盐类及无机酸、盐介质的车间地面。经使用效果尚好。 Water glass has good corrosion resistance, but due to its poor resistance to water, acid, and impermeability, its use is limited. At the beginning of 1970, we built a part of the water glass melamine mortar floor and used the method of incorporation of furfuryl alcohol resin to improve its water resistance and acid resistance and incorporate asbestos wool to reduce its shrinkage cracks. It has been officially applied to the workshop floor with organic acids, organic salts, and inorganic acids and salt media. The use of the effect is still good.
