一、 甲基硅酸鉀是一種新型剛性建筑防水材料，具有良好的滲透性。其分子結(jié)構(gòu)中的硅醇基與硅酸鹽材料中的硅醇基反應(yīng)脫水交聯(lián)，從而實現(xiàn)"反毛細(xì)管效應(yīng)"形成優(yōu)異的憎水層，同時具有微膨脹、增加密實度功能。這就是有機硅防水劑具有高效防水作用的機理。

Introduction: Potassium methyl silicate is a new type of rigid building waterproof material with good penetrating crystallinity. The silanol group in the molecular structure reacts with the silanol group in the silicate material to dehydrate and crosslink, thereby realizing the "anti-capillary effect" to form an excellent hydrophobic layer, and has the functions of micro-expansion and increased compactness. This is the mechanism by which silicone water repellents have an efficient waterproofing effect.
