Recycled Pet(再生宠物)研究综述
Recycled Pet 再生宠物 - Long term durability performance of recycled PET-fibre reinforced cement composite can be achieved (Won et al. [1] Accordingly, NIR spectroscopy is demonstrated as a suitable method for in-line quality monitoring during extrusion foaming of recycled PET, being especially prone to quality fluctuations. [2] The contaminants decrease the mechanical properties of the recycled PET. [3] A new 390 mL bottle made of recycled PET will be available in select states start. [4] The miscibility of such recycled LLDPE (rLLDPE) in recycled PET (rPET) is enhanced by the incorporation of a compatibilizer and the PET molecular architecture is maintained using a chain extender, which governs its melt strength. [5] Based on the theory of collaborative entropy, this study constructs an integrated evaluation and optimization methodology system for the environmental, economic, and social impacts of blanket production from recycled PET, using environmental life cycle assessment, life cycle cost assessment, social life cycle assessment, and sensitivity analysis. [6] Therefore, the use of waste PET in water-borne coatings systems not only reduces the cost of coatings, but also opens up a new market for recycled PET, which may contribute a promising method for management of waste PET. [7] We performed a safety evaluation of the recycling process for producing recycled pulp following the European Food Safety Authority safety assessment for polyethylene terephthalate (PET) bottles using recycled PET. [8] Post consumed polyethylene terephthalate (PET) water bottles were used as a source of recycled PET (r-PET) and blended with commercial grade polypropylene (PP) to produce the center part of low speed wheels. [9] The outcomes of this study also confirmed that the B-PUF prepared from recycled PET not only were composed of a high percentage of waste poly(ethylene terephthalate), which could help reduce the amount of recycled polymer materials and improved waste management but also met the high demands for the fire safety of polymer applications. [10] The materials used consist of recycled PET and virgin PET. [11] To decrease the modulus and increase the mechanical properties of recycled PET by introducing the flexible segments, the recycled polyethylene-terephthalate (PET) was modified by the chain extender produced with 2, 4, 6, 8-tetramethyl-2, 4, 6, 8-tetra (2, 3-epoxypropoxy) propylcyclotetrasiloxane by the hydrosilylation reaction. [12] The developed formulation with recycled PET is a good example of the applicability of work developed at a laboratory scale into industrial-scale production. [13] This research looks for the integration of recycled PET in a constructive element to be used in self-construction; it is sought to verify the viability of the use of PET (Polyethylene terephtha- late) as a construction material; this research is projected considering the rules for bending work of a concrete beam. [14] Density and compressive strength were estimated using virgin (V-PET) and recycled PET (R-PET). [15] In this work we have evaluated the difference in desorption rate of model contaminants from recycled PET in dry air and nitrogen atmosphere by thermogravimetric analysis. [16] Because of a considerable drop in molecular weight in the course of recycling, recycled PETs are not suitable for engineering uses. [17] The method used was CML 2 baseline 2000 method, and the results showed that the scenario S3 had the least environmental impacts on most of the impact categories due to use of recycled PET and PE flakes as substitution for virgin PET and PE flakes and also due to less emissions during recycling process of these two plastic wastes. [18] The use of recycled PET as a reinforcement component in elastomers enhances the performance of the resultant blend. [19] Emphasis is placed on the influence of controlled copolymer structures and glycidyl methacrylate content on physical properties, thermal properties and rheological behavior of recycled PET. [20] Moreover, a redesigned breadboard was produced thru 3D printing using a recycled PET as filament source. [21] Recycled PET had the highest tensile strength at 35 ± 8 MPa. [22] The problem, in part, is that the properties of recycled PET just aren’t as good as those of the virgin polymer. [23] Water absorption of recycled PET was found to be 0. [24] The current study may help overcome the drawback of intrinsic high flammability and enlarge the fire safety applications of materials with a high percentage of recycled PET. [25] Although it is not intended to take part in the manufacture of polyethylene terephthalate (PET) food grade, the presence of BPA in recycled PET should not be neglected. [26] VOCs emissions from recycled PET are recognized as one of the major causes of poor healthy condition. [27] Recycled PET (polyethylene terephthalate) resin (as binder) with fly ash, red mud and silica fume has been manually mixed, molded and cured for final fabrication. [28] Here, elemental sulfur was combined with diallyl sulfide (DAS), diallyl disulfide (DADS), and garlic essential oil (GEO) to form adhesive polymers from recycled petroleum waste and renewable monomers. [29]可以实现再生 PET 纤维增强水泥复合材料的长期耐久性能（Won et al. [1] 因此，近红外光谱被证明是在回收 PET 挤出发泡过程中在线质量监测的合适方法，特别容易出现质量波动。 [2] 污染物降低了回收PET的机械性能。 [3] 由回收 PET 制成的新 390 mL 瓶子将在选定的州开始提供。 [4] 这种回收的 LLDPE (rLLDPE) 在回收的 PET (rPET) 中的混溶性通过掺入相容剂得到增强，并且使用控制其熔体强度的扩链剂保持 PET 分子结构。 [5] 本研究基于协同熵理论，采用环境生命周期评估、生命周期成本评估、社会生命周期评估、和敏感性分析。 [6] 因此，在水性涂料体系中使用废PET不仅降低了涂料的成本，而且为再生PET开辟了一个新的市场，这可能为废PET的管理提供一种很有前景的方法。 [7] 根据欧洲食品安全局对使用回收 PET 的聚对苯二甲酸乙二醇酯 (PET) 瓶的安全评估，我们对生产回收纸浆的回收过程进行了安全评估。 [8] 消费后的聚对苯二甲酸乙二醇酯 (PET) 水瓶被用作回收 PET (r-PET) 的来源，并与商业级聚丙烯 (PP) 混合以生产低速车轮的中心部分。 [9] 这项研究的结果还证实，由回收 PET 制备的 B-PUF 不仅由高比例的废聚对苯二甲酸乙二醇酯组成，有助于减少回收聚合物材料的用量和改善废物管理，而且满足对聚合物应用的防火安全性提出了很高的要求。 [10] 使用的材料包括再生 PET 和原生 PET。 [11] 为了通过引入柔性链段来降低再生 PET 的模量并提高机械性能，再生聚对苯二甲酸乙二醇酯 (PET) 用 2, 4, 6, 8-tetramethyl-2, 4, 6 生产的扩链剂进行改性，通过氢化硅烷化反应得到8-四(2, 3-环氧丙氧基)丙基环四硅氧烷。 [12] 使用回收 PET 开发的配方是实验室规模开发的工作适用于工业规模生产的一个很好的例子。 [13] 本研究寻求将回收的 PET 整合到用于自建的建设性元素中；试图验证使用 PET（聚对苯二甲酸乙二醇酯）作为建筑材料的可行性；这项研究是考虑到混凝土梁弯曲工作的规则而进行的。 [14] 使用原始 (V-PET) 和回收 PET (R-PET) 估算密度和抗压强度。 [15] 在这项工作中，我们通过热重分析评估了再生 PET 在干燥空气和氮气气氛中的模型污染物解吸速率的差异。 [16] 由于在回收过程中分子量显着下降，回收的 PET 不适合工程用途。 [17] 使用的方法是 CML 2 基线 2000 方法，结果表明，情景 S3 对大多数影响类别的环境影响最小，因为使用回收的 PET 和 PE 薄片替代原始 PET 和 PE 薄片，并且还由于这两种塑料废物在回收过程中的排放量更少。 [18] 使用回收的 PET 作为弹性体中的增强成分可提高所得共混物的性能。 [19] 重点放在受控共聚物结构和甲基丙烯酸缩水甘油酯含量对再生 PET 的物理性能、热性能和流变行为的影响。 [20] 此外，使用回收的 PET 作为灯丝来源，通过 3D 打印生产了重新设计的面包板。 [21] 再生PET的抗拉强度最高，为35 ± 8 MPa。 [22] 部分问题在于，再生 PET 的性能不如原始聚合物的性能好。 [23] 发现回收PET的吸水率为0。 [24] 目前的研究可能有助于克服固有的高可燃性的缺点，并扩大具有高回收 PET 百分比的材料的防火应用。 [25] 虽然它不打算参与食品级聚对苯二甲酸乙二醇酯 (PET) 的制造，但不应忽视回收 PET 中 BPA 的存在。 [26] 回收 PET 的 VOC 排放被认为是导致健康状况不佳的主要原因之一。 [27] 回收的 PET（聚对苯二甲酸乙二醇酯）树脂（作为粘合剂）与粉煤灰、赤泥和硅灰经过人工混合、成型和固化，以用于最终制造。 [28] 在这里，元素硫与二烯丙基硫醚 (DAS)、二烯丙基二硫醚 (DADS) 和大蒜精油 (GEO) 结合，从回收的石油废料和可再生单体中形成粘合剂聚合物。 [29]

The present work demonstrates an environmentally-friendly nanofiltration membrane with high performance prepared by recycled PET bottles. [1] UPOFA was used as a partial replacement binder in varied proportions (20% and 40%) of the total cement binder, whereas shredded recycled PET bottles were added as reinforced fibre by 1% of the total mix volume.
