摘要:
A process for the preparation of thermal insulation sheets fashioned from certain unseparated mixtures of post-consumer plastic articles and the article, itself, is disclosed. The mixtures of such articles contain polyethylene terephthalate (PET) and polystyrene (PS) and optionally also articles made of high density polyethylene (HDPE). An unseparated mixture of such articles is provided. This mixture is crushed and shredded to form plastic flakes, and these plastic flakes are then homogenized. Homogenization of the flakes can be carried out either by melt-blending them or by further comminution to produce very fine particles of the mixed plastics. The resulting homogenized mixture of plastic types is then compression molded into sheets ranging in thickness from about 3 to 10 mm.
摘要(中):
公开了一种制备由消费后塑料制品的某些未分离的混合物和制品本身制成的隔热片的方法。 这些制品的混合物含有聚对苯二甲酸乙二醇酯(PET)和聚苯乙烯(PS),以及任选的还包括由高密度聚乙烯(HDPE)制成的制品。 提供这种制品的未分离的混合物。 将该混合物粉碎并粉碎以形成塑料薄片,然后将这些塑料薄片均化。 薄片的均质化可以通过熔融共混或进一步粉碎来制造混合塑料的非常细小的颗粒。 然后将所得到的均质化塑料混合物压塑成厚度为约3至10毫米的片材。
