区分色彩暗淡的挤塑板的窍门
作者:admin 来源:本站 发布时间:2017-01-13 17:15:12 浏览次数:416

看收回料很简单,色彩暗淡越申,用的回收料越多。看质量均匀与否的办法,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。
Look back material is very simple, the color is more bleak, the more recycled materials used. The quality is uniform or not to the sheet with something to see section of knife cut off. The color of the skin is deep, the center is shallow, the material is uneven, and the skin is much harder than the central material. Such a board feels very hard, in fact, the compressive strength is not high. Due to the low intensity of the central layer.

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。(表皮应力大,中心和外表的缩短胀大不一致)。有些很烂的xps挤塑板不必切,一看就是废物塑料的固态版别。
Just because the epidermal process is not up to the requirements of extruded sheet materials uneven plate used in external insulation is a relatively easy problem. (skin stress, the appearance of the center and shorten the swell of inconsistent). Some bad XPS board will not cut, is a look at the types of solid waste plastic.
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。
The color of the recycling material is not good, and has an effect on the thermal conductivity. Foaming agent run fast, thermal resistance falling fast. And recovery material is more flammable, it is difficult to increase the flame retardant, so basically do not 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。
Recovery of dark color material in repeated melting under the effect of the molecular chain becomes very short - melt index is not up to the good target, resulting in inadequate and uneven foam, bubble hole is very thick, sturdy, skin is very brittle, high strength, large bulk contraction, while the thermal conductivity coefficient will be higher, the burning level is very low, the durability is poor.
不该该有的那就是起泡,裂口,变形一个都不该有,更不必去谈数量和长度。
It should not have been that bubble, crack, deion should not have one, not to mention the number and length.
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 the board produces mechanical normal, polystyrene materials, accessories, foaming agent, quality, promote the number of normal, no change in electrical conditions. Extruded sheet should be made uniform to the lubrication. There will be no blisters, cracks, deion.
