The Effect Of Non-woven Fabric In Coating Waterproof Construction

In household waterproofing construction, a small inconspicuous object-non-woven fabric is often used. Why use non-woven fabrics? What is the non-woven fabric used for? Today, let us take a look at this seemingly insignificant gadget from the beginning. Non-woven fabric 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. It just aligns or randomly arranges short textile fibers or filaments 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 is the effect of glass fiber mesh non-woven fabric? With its own moisture-proof, breathable, and flexible properties, non-woven fabrics can be closely combined with waterproof coatings. At the same time, the more important effect of non-woven fabrics on waterproofing is to strengthen the effect and resist 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 notify us: we need to hang a net to solve it. This net is a glass fiber mesh cloth, which is used to resist concrete and putty shortening.的拉力。 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. The use of non-woven fabrics to strengthen the Yin and Yang angles of concrete Why does the concrete crack. The fundamental effect of non-woven fabrics in waterproof construction has been clarified. With the energy of breaking the casserole, let’s talk about why the concrete cracks. Where did the crack come from? We know that when the house is being built. In order to prevent concrete from cracking, steel bars should be added to resist the strong tensile force caused by the shrinking process of concrete. However, steel bars cannot completely offset the tensile force brought by concrete, so it will still crack (concrete cracking is a normal phenomenon, because concrete works with cracks, and there are many reasons for concrete cracking, so I won't repeat them here). "One cloth and three coatings" technology The concrete will crack, and there are many tiny holes in the center of the concrete. Water will leak through these holes and cracks. That's why there is the saying that "water is all-permeable". In order to make the waterproof coating better resist water intrusion, smart waterproof people invented the waterproof coating, and in order to better exert the tensile and crack resistance of the waterproof coating, non-woven fabric was added as a reinforcement. That's why we have common techniques such as "one cloth, three coats", "two cloths, five coats" and so on. Wow, the small non-woven fabric has such a big effect!
