Detailed interpretation of the role of non-woven fabrics in waterproof construction

In the process of house decoration, waterproofing is a very critical step. When waterproofing construction, we often use polyester non-woven fabrics. Its role is not small. What are non-woven fabrics used for? Next, we will look at the role of non-woven fabrics in coating waterproof construction. Non-woven fabric (non-woven fabric, non-woven cloth) refers to non-woven fabric, or non-woven fabric. It is a fabric that does not need to be spun and weaves, but the short fibers or filaments are oriented or randomly arranged to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods. It has the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low price, and recyclable. What are the functions of the 'Three Coating and One Cloth' process non-woven fabrics? Our common 'three-coating and one-cloth' process method, in order to better exert the tensile crack resistance of the waterproof coating, non-woven fabric is added as a reinforcement. The reason why there is a saying that “water is all-permeable” is because there are many small holes in the middle of the concrete, and the water will follow these holes and cracks and leak down, and the concrete will crack. Due to the moisture-proof, breathable, and flexibility of the non-woven fabric, the non-woven fabric can be closely combined with the waterproof coating. At the same time, the more important role of non-woven fabrics for waterproofing is strengthening and resistance to tensile cracking. How to resist tensile cracking? To give a very simple example, when we are decorating, when there are small cracks on the wall, the painter will tell us: we need to hang a net to solve it. This net is fiberglass mesh cloth, which is used to resist the shrinkage of concrete and putty. The pull. Similarly, the non-woven fabric used in the waterproof construction process is also used as a reinforcement to strengthen the tensile performance of the paint coating, so that the waterproof coating forms a whole, so that it does not leak water.
