在家庭防水施工中,常常会用到一个不起眼的小物件——无纺布。 为什么要用到无纺布呢?无纺布是用来干什么用的呢?今日就带咱们一起来从头认识一下这个看似无关紧要的小玩意。 无纺布 无纺布是指非织造布,或叫不织布。是一种不需要纺纱织布而构成的织物,只是将纺织短纤维或许长丝进行定向或随机撑列,构成纤网结构,然后采用机械、热粘或化学等方法加固而成。具有防潮、 透气、柔韧、质轻、不助燃、容易分解、无毒无刺激性、颜色丰厚、价格低廉、可循环再用等特色。 玻纤网格布 无纺布的效果是什么? 其本身的防潮、透气、柔韧性,使得无纺布可以和防水涂料紧密结合。一起,无纺布关于防水更重要的效果是——加强效果,抗拉裂。 怎样抗拉裂呢?举一个很简单的比如,咱们在装修的时分,当墙面有细微裂缝,油漆师傅会通知咱们:要挂网才能解决,这个网就是玻纤网格布,用来抵挡混凝土、腻子缩短带来的拉力。 同样,防水施工过程中使用的无纺布,也是用来作为加强,加强涂料涂层的抗拉性能,使防水涂层构成一个整体,从而不漏水。 使用无纺布对阴阳角加强 混凝土为什么会开裂 无纺布在防水施工中的根本效果搞清楚了,本着打破砂锅问底的精力,咱们再来说说为什么混凝土会开裂。 裂缝从哪来的呢?咱们知道,在建房子的时分。为了避免混凝土开裂,要加入钢筋,用来抵挡混凝土干缩过程中带来的强壮拉力。可是,钢筋并不能完全抵消混凝土带来的拉力,所以仍是会开 裂(混凝土开裂是很正常的现象,因为混凝土就是要带裂缝工作的,并且混凝土开裂有许多原因,这儿就不赘述了)。 “一布三涂”工艺工法 混凝土会开裂,并且混凝土中心有许多细微的孔洞,水就会顺着这些孔洞和裂缝,渗漏下去,所以才有了“水是无孔不入的”说法。 为了使防水涂层能够更好地抵挡水的入侵,聪明的防水人就发明了防水涂料,而为了更好地发挥防水涂料的抗拉裂性能,又增加了无纺布来作为加强。所以才有了咱们常见的“一布三涂”“两 布五涂”等工艺工法。 哇,本来小小的无纺布有这么大的效果!长见识了没?
In home waterproof construction, a small object, non-woven fabric, is often used. Why use non-woven fabrics? What is nonwoven used for? Let's meet this seemingly insignificant gadget from the beginning today. Nonwoven refers to nonwovens, or nonwovens. It is a kind of fabric that does not need spinning and weaving. It is only made up of short textile fibers or filaments, which are oriented or randomly strung to form a fiber net structure, and then reinforced by mechanical, thermal or chemical methods. It is moisture-proof, breathable, flexible, light, non combustion supporting, easy to decompose, non-toxic and non irritant, rich in color, low in price and recyclable. What is the effect of fiberglass mesh nonwoven? Its own moisture-proof, air permeability, flexibility, so that non-woven fabric and waterproof coating can be closely combined. Together, the more important effect of non-woven fabric on waterproof is strengthening effect and anti cracking. How to resist crack? For example, when we are decorating, when there is a slight crack on the wall, the painter will inform us that we need to hang a net to solve it. This net is a glass fiber mesh cloth, which is used to resist the tension caused by the shortening of concrete and putty. Similarly, the non-woven fabric used in the waterproof construction process is also used to strengthen the tensile property of the coating, so that the waterproof coating forms a whole, so as to prevent water leakage. The use of non-woven fabric to strengthen the internal and external corners of the concrete why the cracking of non-woven fabric in the waterproof construction of the basic effect of clear, in order to break the energy of the casserole bottom, let's talk about why the concrete will crack. Where did the crack come from? We know when the house is under construction. In order to avoid concrete cracking, steel bars should be added to resist the strong tensile force caused by concrete shrinkage. However, the reinforcement can not completely offset the tension brought by the concrete, so it will still crack (concrete cracking is a very normal phenomenon, because the concrete is to work with cracks, and there are many reasons for concrete cracking, which will not be covered here). "One cloth, three coating" process concrete will crack, and there are many tiny holes in the center of the concrete, water will leak down these holes and cracks, so there is the saying that "water is all pervasive". In order to make the waterproof coating better resist the invasion of water, intelligent waterproof people invented the waterproof coating, and in order to better play the tensile crack performance of the waterproof coating, non-woven fabric was added as a reinforcement. So we have the common "one cloth, three coats", "two cloth, five coats" and other technological methods. Wow, the original small non-woven fabric has such a big effect! Have you seen it?
