山东挤塑板的检测方法!

  对于发达国家而言,挤塑板的市场是十分巨大的。据不完全统计,它的人均销量,美国0.76立方米、挪威0.70立方米、芬兰0.51立方米、德国0.41立方米、奥地利0.38立方米、比利时0.30立方米、法国0.27立方米,对于欧洲市场来说,绝热材料的销量为每年9千万立方米,价值四百亿人民币。
For developed countries, the market of Extrusion board is very huge. According to incomplete statistics, its per capita sales are 0.76 cubic metres in the United States, 0.70 cubic metres in Norway, 0.51 cubic metres in Finland, 0.41 cubic metres in Germany, 0.38 cubic metres in Austria, 0.30 cubic metres in Belgium and 0.27 cubic metres in France. For the European market, the sales of insulation materials are 90 million cubic metres per year, worth 40 billion RMB.
在上面所提到的巨大市场中,泡沫塑料占三分之一。换言之,聚苯乙烯、聚氨酯等材料组成的绝热材料欧洲市场上的年销售量超过三千万立方米,美国二千万立方米。 我国的绝热材料市场起步较晚,特别是有机类的绝热材料的市场开发更是滞后。
Foam plastics account for one-third of the huge market mentioned above. In other words, polystyrene, polyurethane and other insulation materials are sold more than 30 million cubic meters a year in Europe and 20 million cubic meters in the United States. The market of thermal insulation materials in China started late, especially the market development of organic thermal insulation materials is lagging behind.
长期以来,大量的使用集中在包装上。但是近年来,随着经济的发展和国外技术的进入,挤塑板在建筑上的使用取得了极大的发展,仅限于用于建造厂房的彩钢夹芯板的聚苯乙烯、聚氨酯的用量每年就超过150万立方米,其中大量使用的是二次发泡的EPS,随着经济的发展,这个市场势必还要扩大,而且将有很大的一块市场将被XPS挤塑板取代。
For a long time, a lot of use has been concentrated on packaging. However, in recent years, with the development of economy and the entry of foreign technology, the use of extruded plastic sheets in construction has made great progress. The consumption of polystyrene and polyurethane used for building color steel sandwich panels is more than 1.5 million cubic meters per year. The EPS with secondary foaming is widely used. With the development of economy, this market will inevitably expand, and it will also expand. There is a big market that will be replaced by XPS extruded panels.

对挤塑板科学的检测方法是要看它的:导热系数、抗压强度、透水率、尺寸稳定性、防火等级等指标,当然这些需要在实验室里完成!

The scientific testing method of extruded sheet depends on its thermal conductivity, compressive strength, permeability, dimensional stability, fire protection grade and other indicators, of course, these need to be completed in the laboratory!
简单的区分挤塑板好坏的方法:
Simple method to distinguish the quality of extruded sheet:
1、看表面是否光滑平整无裂痕
1. See if the surface is smooth and smooth without cracks.
2、在表面用指压是否坚硬,一捅即破为差板
2. Whether it is hard to press with fingers on the surface, it will break into a difference plate at one stroke.
3、整张板是否弯曲变形,好板应该平整
3. Whether the whole sheet is bent or not, the good sheet should be flat.
4、从侧面揪一小块下来,看是否有弹性,好板,捏后有弹性可恢复;一捏即扁,无弹性为差
4. Grab a small piece from the side to see if there is elasticity, good board, elasticity can be restored after pinching; one pinch is flat, inelasticity is poor.
5、对于阻燃板,B1为点火不燃,B2为离火自熄
5. For flame retardant panels, B1 is ignition-free and B2 is off-fire self-extinguishing.
切记,容重不是检测挤塑板的标准,并非容重高就是好板,容重是可以添加其他塑料来完成的!
Keep in mind that bulk density is not the standard of testing extrusion board, it is not high bulk density or good board, bulk density can be added to other plastics to complete!
