The role of water-resistant and waterproof non-woven fabrics in the coating and waterproof construction of domestic waterproof buildings

What is non-woven fabric used for? Today, let us take a look at this seemingly insignificant gadget. 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 require weaving and weaving. It is made only by placing short fibers or filaments in an oriented or random manner to form a fiber network structure, and then strengthening it with mechanical, thermal or chemical methods. It is moisture-proof, breathable, flexible, light in weight, non-flammable, easy to decompose, non-toxic and non-irritating, bright in color, cheap and good in quality, and recyclable. What is the function of glass fiber mesh non-woven fabric? It is moisture-proof, breathable and flexible, so that the non-woven fabric is closely combined with the waterproof coating. At the same time, the more important role of non-woven fabrics used for waterproofing is to strengthen the effect of stretching cracks. How to resist tensile cracks? To give a very simple example, when we decorate, when there are cracks on the wall, the painter can tell us: the ability to hang nets, this net is glass fiber mesh, used to resist the tension of children's shrinkage to bring concrete, bored. Similarly, the non-woven fabric used in the waterproof construction process is also used as a reinforcement to enhance the tensile performance of the coating coating, so that the waterproof coating forms a whole, so as not to leak. The use of non-woven fabrics to enhance the Yin and Yang angles Why concrete cracks The basic function of non-woven fabrics in waterproof construction is clear. In the spirit of breaking the casserole, let's talk about why concrete cracks. Where did the crack come from? We know that when building a house. In order to prevent the concrete from cracking, steel bars are added to resist the strong tensile force caused by the drying shrinkage of the concrete. However, the steel bar cannot completely offset the tension caused by the concrete, so it will still crack. 'One cloth and three coating' process The concrete cracks, and the concrete has many small holes in the middle. Water will follow these holes and cracks and leak down, so there is 'water is all-permeable'. To make waterproof coatings better able to withstand the attack of water, smart waterproof people invented waterproof coatings, and in order to better play the tensile crack resistance of waterproof coatings, and then add non-woven fabric as a strengthening agent. So we have a common 'one cloth, three coatsRelated tags: Previous: The standard review meeting of 'Textiles, Nonwovens for Isolation Clothing' was held in Suzhou on December 19.
