地暖保温板硬薄哪种较好?
作者:admin 来源:本站 发布时间:2017-12-26 18:29:06 浏览次数:318
前几年,国内地暖保温有用发泡水泥,也有用挤塑板的。但后者一般都是劣质挤塑板,抗压性能、厚度、环保性、吸水率等都基本不合格。
In the past few years, domestic thermal insulation is useful for foamed cement, and it is also useful for extruding board. However, the latter is generally low quality plastic plate, the compression performance, thickness, environmental protection, water absorption and so on are basically unqualified.

后来因为地暖辅材标准化、集成化、品牌化,挤塑板的各项参数和要求都有提升。各挤塑板厂家也不断竞争,纷纷提高挤塑板的硬度。同时,为了“满足”消费者对层高的要求,在选材施工时,有的减少保温层厚度,有的减少回填层厚度,提出了超薄地暖和干式地暖的概念。

Later, because the ground is warm, standardization, integration, auxiliary brand, plastic extruded board parameters and requirements have improved. The manufacturers of the extruded board are also constantly competing to improve the hardness of the extruded board. At the same time, in order to "satisfy" the requirements of consumers for storey height, during the selection and construction, some reduce the thickness of the insulation layer, and some reduce the thickness of the backfill layer, and put forward the concept of ultra-thin floor heating and dry ground heating.
济南挤塑板厂家通过增加成核剂滑石粉的添加量,来达到增加挤塑板密度和抗压强度的效果。因为滑石粉比聚苯乙烯原料便宜很多。
Ji'nan extruded plate manufacturers can increase the density and compressive strength of the extruded plate by adding the amount of the talcum powder added to the nucleating agent. Because talcum powder is much cheaper than polystyrene.
副作用就是挤塑板的实际密度不达标,导热系数过大。而且滑石粉也会降低挤塑板的导热系数,更加导致挤塑板保温性降低。增加硬度还有一种方式:增加挤塑板表面结皮厚度来增加硬度。但是,为了不增加成本,其实挤塑板中间部分会更软。地暖使用后,因蠕变量大,时间一久容易出现地面开裂,走路有声等问题。
The side effect is that the actual density of the extruded plate is not up to the standard, and the thermal conductivity is too large. And the talcum powder also reduces the thermal conductivity of the extruded plate, and leads to the decrease of the thermal insulation of the extrusion plate. Another way to increase the hardness is to increase the thickness of the surface of the extrusion plate to increase the hardness. However, in order not to increase the cost, the middle part of the extruded board will be softer. After the use of ground heating, because of the large vermicular variable, it is easy to crack on the ground for a long time, and walk with sound and so on.
