在家居防水施工中，经常使用一种不起眼的小物件——无纺布。为什么使用无纺布?这些无纺布是用来做什么的?今天，让我们从一开始就来看看这个看似微不足道的小玩意。无纺布无纺布(Non-woven fabric, Non-woven cloth)是指无纺布，或无纺布。它是一种不需要纺纱和编织的织物。它只是将短的纺织纤维或长丝排列或随机排列，形成蛛网结构，然后通过机械、热粘接或化学方法增强。具有防潮、透气、柔韧、重量轻、不燃、易分解、无毒无刺激性、色彩丰富、价格低廉、可回收利用等特点。玻璃纤维网无纺布的作用是什么?无纺布具有自身的防潮、透气、柔韧性，可与防水涂料紧密结合。 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!
