如何识别回收的挤塑板
作者:admin 来源:本站 发布时间:2017-04-06 16:44:37 浏览次数:220
  看质量是否均匀的方法,将板材用东西刀堵截,看断面的状况。表皮色彩深,中心浅说明材料不均匀,并且表皮会比中心材料硬许多。这样的板摸起来很硬,其实抗压强度并不高。由于中心层强度低。表皮硬是由于工艺达不到要求挤塑板材料不均匀的板用在外保温是比较容易出问题的。
Whether quality is uniform, the method of plate with knife block, to see the status of the cross section. Skin color is deep, the center light material uneven, and the skin is better than hard many center materials. The board feels very hard, in fact, the compressive strength is not high. Because the center layer of low intensity. Skin just because the technology can not meet the requirements extruded plate material uneven plate with outer insulation is more problematic. 
色彩暗淡的回收料的细胞布局欠好,对导热系数有影响。发泡剂跑得快,热阻下落快。并且收回料更易燃,很难增加阻燃剂,所以基本上都不阻燃。

Color dim recycling material cell layout owe good, have an effect on thermal conductivity. Foaming agent runs fast, heat resistance falling fast. And take more flammable material, it is difficult to increase the flame retardants, so basically don't flame retardant.

色彩暗淡的回收料在重复熔化的效果下,分子链变得很短,熔融指数达不到很好的目标,致使发泡不充分、不均匀,泡孔孔壁很厚,表皮很坚固、易脆,紧缩强度很高、容重很大,而导热系数会较高、焚烧等级很低、耐久性很差。
Color dim recycled materials under repeated fusion effect, molecular chain become very short, melt index reach a good goal, the foam is not sufficient, asymmetrical, bubble distributed wall is very thick, epidermis is very strong, brittle, tightening high strength, bulk density is large, and the coefficient of thermal conductivity will be high, burning level is very low, very poor durability. 
若是挤塑板出产机械正常,聚苯乙烯材料,辅料,发泡剂,质量、推动数量正常,电气条件无变化。出产出来的挤塑板就应该是润滑,均匀一至的。跟本不会存在起泡,裂口,变形。
If produce extruded board machine is normal, polystyrene materials, auxiliary materials, foaming agent, quality and the quantity is normal, electrical conditions no change. Yield of extruded board should be lubricated, even one to. With no bubbles, cracks, deion.
