How can liquid sodium methyl silicate play a moisture-proof role in the field of building waterproofing?

The principle of moisture-proofing of liquid sodium methyl silicate

The molecular structure of liquid sodium methyl silicate contains silanol groups (-Si-OH), which is the key to its moisture-proof function. When it is applied to the surface or interior of a building material, the silanol base will react chemically with the silicate components in the building material (such as cement, masonry, etc.). Specifically, the silanol group and the silanol group in the material are cross-linked by dehydration to form a tight and stable mesh structure. This process is called the "anti-capillary effect", which effectively clogs capillary pores inside the material and prevents moisture from penetration.
At the same time, sodium methyl silicate will also produce a slight expansion during the reaction process, further filling the tiny gaps inside the material, increasing the density of the material, thereby improving the waterproof and moisture-proof performance of building materials in all aspects. This modification from the microstructure of the material makes it difficult for moisture to find a channel for penetration in the material, creating a strong moisture-proof barrier for the building.

Application scenarios in building waterproofing

Concrete structure waterproofing: Whether it is the foundation of a building, the basement wall, or concrete structures such as bridges and tunnels, liquid sodium methyl silicate can show off its skills. Adding it to the concrete mixing process, or surface spraying after concrete pouring can form a hydrophobic network inside the concrete, effectively preventing the corrosion of external moisture such as groundwater and rainwater, avoiding the problems of decreasing strength and corrosion of steel bars caused by long-term moisture, and greatly improving the durability of the concrete structure.
Moisture-proof of brick and stone walls: Liquid sodium methyl silicate is also suitable for the restoration and protection of exterior walls, interior walls and ancient buildings of brick and stone structures. By applying or impregnating, it can penetrate deep into the masonry and react with the silicates in the masonry to form a transparent and long-lasting waterproof film on the surface. This waterproof film can not only block the penetration of rainwater, but also maintain the breathability of masonry and stone, allowing moisture inside the wall to be discharged normally, prevent mold, alkaline and other phenomena on the wall, and maintain the beauty and structural stability of the wall.
Roof waterproofing: The roof is exposed to the natural environment for a long time and is subject to the test of various factors such as rainwater and ultraviolet rays. Liquid sodium methyl silicate can be used as a key component of roof waterproof coatings, or directly used for roofing base treatment. It can form a continuous and dense waterproof coating on the roof, effectively resisting the erosion of rainwater, preventing roof leakage, and providing reliable waterproof protection for indoor space.

Advantages over other moisture-proof materials

Compared with traditional asphalt-based waterproof rolls, polymer waterproof rolls and other moisture-proof materials, liquid sodium methyl silicate has many significant advantages. First of all, it has good permeability and can be waterproofed deep into the building materials instead of just forming a layer of cover on the surface, making the waterproofing effect more lasting and reliable. Secondly, sodium methyl silicate is an aqueous product, non-toxic, odorless and pollution-free, and meets the requirements of modern buildings for environmentally friendly materials and will not cause harm to the human body and the environment during construction and use. In addition, its construction process is relatively simple, and it can be used for spraying, brushing, dipping and other methods. It is suitable for construction parts of various complex shapes and structures, and the construction cost is relatively low.
