再生料挤塑板使用过程中的缺点
作者:admin 来源:本站 发布时间:2017-11-21 17:57:31 浏览次数:384
如今市场上遍及选用的保温板都是挤塑板,如今市场上最常见的挤塑板有两种:一种是选用新质料制作而成的原生料挤塑板,还有一种就是选用废旧的塑料收回今后制作的再生料挤塑板,再生料的挤塑板有两个致命的缺陷,这两个致命缺陷就必定给建筑带来严重火灾危险。
Now on the market in the selection of insulation board are extruded board, a plastic board is now the most common on the market: one is the raw material selection of new plastic extruded board made of, there is a selection of waste plastic recycling materials in the future to recover the extruded board, plastic extruded board of renewable materials 2 a fatal flaw, the fatal flaw will bring serious danger to the building fire.

首先,因为再生料挤塑板的物理性能是十分差的,大概运用两年今后就会呈现挤塑板附近向外翘起即所谓的翘边景象,翘边的挤塑板衔接处就会呈现开裂,使易燃保温板暴露在建筑物外表。

First of all, because the physical properties of recycled material extrusion board is very poor, it will probably be two years later, it will appear near the extrusion plate outward, that is called the "edge" phenomenon, the edge of the extruded plastic plate will crack, so that flammable insulation panels exposed to the exterior of the building.
其次,再生料挤塑板的出产的技术是将质料在加热后挤塑成型,所以,保温板中十分重要的增加剂阻燃剂在加工的过程中很简单蒸发而不宜留存。
Secondly, the production technology of recycled material extrusion board is to make the material extruded after heating, so the very important additive flame retardant in the heat preservation board is very simple to evaporate and not to be retained.
再次,再生料挤塑板因原材料重复收回,致使板子色泽较差,因而大部分厂家都选用增加颜料的方法将板子变为另一种颜色,意图是掩盖再生料的本性,所以这种板子一般气味较大,冲鼻难闻,对人体有害。
Again, recycled plastic extruded board of raw materials due to repeated recovery, resulting in poor color board, so most manufacturers will increase the selection method of pigment board into another color, cover intention is recycled in nature, so the board generally smells great, Chongbi bad, harmful to the human body.
