挤塑板的密度跟质量关系大不大

掌握一定物理知识的朋友都知道,很多物品的质量跟密度、体积都有非常重要的关系。当然,对于保温材料之一的挤塑板也不例外,质量跟密度的关系到底有多大呢?下面就来看看吧。
Friends who have mastered a certain physical knowledge know that the quality of many items has a very important relationship with the density and volume. Of course, for one of the thermal insulation materials, the extrusion plate is no exception. How much is the relationship between the quality and the density? Let's take a look below.

山东挤塑板通过各种方式降低XPS挤塑板密度是国内XPS工业发展的主要方向,全新料聚苯乙烯颗粒经二次真空发泡技术,能将密度降至最低22公斤每立方米左右。但实际上,国内挤塑板的密度均在28-30公斤每立方米左右,这是因为国内挤塑板产业基本上都采用回收料进行生产,回收料的流动性较低,发泡困难,发泡的密度在30公斤每立方米已经为技术极限。

Shandong Extrusion board reduces the density of XPS extruded panel in various ways, which is the main direction of the development of XPS industry in China. The new material polystyrene particles can reduce the density to a minimum of 22 kg per cubic meter after two vacuum foaming technologies. But in fact, the domestic plastic extruded board density were 28-30 kilograms per cubic meter, this is because the domestic plastic board industry is basically using recycled materials for production, recycling of solid flow low foaming difficult, foaming density of 30 kilograms per cubic meter for technical limit.
在原料的等级,泡孔结构一致的情况下,挤塑板的强度和密度大致成正比关系。35公斤级密度的挤塑板抗压强度相较30公斤级挤塑板密度高出30%左右,而一些高抗压的铁路基材用板,密度均在45公斤每立方米之上,抗压能达到700KPA以上。
The strength and density of the extruded plate are roughly proportional to the grade of raw materials and the uniform structure of the foam. The compressive strength of 35 kilogram density extruded plate is 30% higher than that of 30 kilogram grade extruded plate, while some high compressive railway substrate boards are all above 45 kg per cubic meter, and the compressive strength is above 700KPA.
