“防水保温一体化系统”解决的是什么问题?

一、 抗窜水问题
First, anti channeling problem.
窜水问题一直是困扰业界的一个难题,而单层柔性屋面系统中也同样存在。
The problem of water channeling has always been a difficult problem for the industry, and the single layer flexible roof system also exists.
在传统屋面做法中,由于防水层、保温层分开施工,一旦防水层出现破损就会导致水四处窜流,不仅防水效果得不到保证,也大大影响了保温效果,因为传统单层柔性屋面中保温层施工完后再施工防水层,两道工序之间存在间隔时间,对于通常采用的岩棉等A级保温材料来说,其吸水性非常强,一旦施工中遇到雨季时,保温层就会吸水导致保温效果失效,只能重新拆除保温层重新施工,还有可能造成积水问题,为渗漏埋下隐患。
In traditional roofing practices, the waterproof layer and insulation layer are separately constructed, once the waterproof layer is damaged, water will flow around, not only the waterproof effect is not guaranteed, but also the insulation effect is greatly affected, because the waterproof layer is constructed after the construction of the insulation layer in the traditional single-layer flexible roof, and there is a gap between the two processes. At intervals, for the commonly used rock wool and other A-class insulation materials, its water absorption is very strong, once the construction meets the rainy season, the insulation layer will lead to water absorption insulation effect failure, can only be re-dismantled insulation layer re-construction, and may cause water problems, for leakage buried hidden dangers.
而防水保温一体化板的防水层和保温层紧密粘结,很好地消除了两者之间的窜水通道,再通过高强度的热风焊接使得上表面的防水层形成一个整体,大大降低了渗漏的概率。
The waterproof layer and insulation layer of the integrated waterproof and thermal insulation board are closely bonded, which eliminates the channeling channel between the two. The waterproof layer on the upper surface is formed as a whole by high strength hot air welding, and the leakage probability is greatly reduced.
二、 抗风揭问题

Two, wind resistance problem

传统单层柔性屋面系统由于防水层和保温层没有有效连接,导致在遭遇大风侵袭时,卷材上方会形成负压,而在负压作用下面层的高分子防水卷材的焊接有可能会被吹开,固定卷材的螺钉也会被拔出,更有甚者整个面层的卷材都会被大风揭掉。
The traditional single-layer flexible roof system has no effective connection between the waterproof layer and the thermal insulation layer, which results in negative pressure on the top of the coil when it is attacked by strong wind. Under the negative pressure, the welding of the high polymer waterproof coil on the surface layer may be blown off, and the screw of the fixed coil will be pulled out, and even the whole coil on the surface layer will be pulled out. It will be blown off by strong winds.
三、防火问题
Three, fire prevention
防水保温一体化板保温隔热芯层采用的是硬泡聚氨酯,它是一种热固性产品,经过阻燃处理后,阻燃级别可以达到各种建筑的要求(可达B1级)。在遇火燃烧时,不会发生熔融滴落现象,同时聚氨酯表面还会碳化结焦,可抑制火势蔓延,从而避免了引燃其他易燃材料来保护建筑结构,而XPS、EPS等为热塑性材料,其在遇火后发生收缩、燃烧并伴有熔融滴落现象,也是之前引起多次火灾的重要原因之一。
Hard foam polyurethane is used as insulation core layer of waterproof and thermal insulation integrated board. It is a thermosetting product. After flame retardant treatment, the flame retardant level can meet the requirements of various buildings (up to B1 level). In the case of fire, melting dropping will not occur, and the surface of polyurethane will be carbonized and coked, which can inhibit the spread of fire, thus avoiding igniting other inflammable materials to protect the building structure. XPS, EPS and other thermoplastic materials, which shrink and burn after fire, accompanied by melting dropping phenomenon, is also before. One of the important reasons for many fires.
