求翻译：甲基硅酸钠是一种单组分固化型合成高分子防水剂材料，主要成份为甲基硅酸盐。其高效防水机理是在水和二氧化碳的作用下，生成甲基硅酸醇，甲基硅酸醇进一步结合并与建筑材料起化学反应，在结构材料表面及内部生成一层几个分子厚的不溶性的防水高分子化合物，网状的有机硅树脂膜。这种树脂膜具有防水、防渗、防潮、防锈、抗老化、抗污染、透气等优点，因而可广泛用于泥砂浆，钢筋混凝土、防水涂料等领域中。用经硫酸铝或硝酸铝中和后稀甲基硅酸钠溶液处理木材、纤维板、纸张等可起到疏水、防腐和提高强度的作用。是什么意思？

Synthesis of methyl-sodium silicate is a one-component curable polymer waterproofing agent material, mainly contain methyl silicate. Its high performance waterproof mechanism is under water and carbon dioxide, silicic acid-methyl alcohol, methyl alcohol silicate building materials react and further integration and, on the surface and internal structure materials generated a few molecule thick insoluble layer of waterproofing macromolecular compound, cellular silicone resin film. This resin membrane waterproof, impervious, moisture, rust-proof, breathable, anti-aging, anti-pollution and so on, which can be widely used in mud mortar, reinforced concrete, waterproofing coatings and other areas. After aluminum sulfate or aluminum nitrate neutralization by dilute sodium methyl silicate solution processing of wood, fibreboard, paper, can play a role of hydrophobic, corrosion protection and increase strength.
