Abstract
The temperatures of the phase transitions for polyethyleneterephthalate samples containing recycled PET (the product Vivilen) and the waste materials from its production were analyzed by differential scanning calorimetry and x-ray structural analysis, and the ratio of the crystalline and amorphous phases was determined. The polyethyleneterephthalate samples were arranged according to their glass transition and melting points, which made it possible to correlate the samples according to the degree of crystallinity. In order to obtain a filament based on the dust waste from the solid-phase polycondensation process an extrusion temperature regime was established, and samples of filaments for 3D printing that meet the requirements of GOST R 59100-2020 were obtained.
通过差示扫描量热法和 X 射线结构分析法，对含有回收 PET（产品 Vivilen）和生产 PET 时产生的废料的聚对苯二甲酸乙二醇酯样品的相变温度进行了分析，并确定了结晶相和无定形相的比例。聚对苯二甲酸乙二醇酯样品根据其玻璃化转变点和熔点进行了排列，这使得根据结晶度对样品进行关联成为可能。为了获得基于固相缩聚过程中产生的粉尘废料的长丝，建立了挤出温度机制，并获得了符合 GOST R 59100-2020 要求的 3D 打印用长丝样品。
