[水利、环境和公共设施管理业,橡胶和塑料制品业] [2013-12-21]
Bioplastics are plastics that have been made from renewable biomass sources or food crops such as vegetable fat, corn starch, vegetable oil, pea starch, and microbiota. The different types of bioplastics available include polymers that are directly extracted from biomass and processed, polymers that are made from bio-based precursors such as PLA, and polymers that are made by bacteria such as PHA and PHB. Bioplastics are different from conventional plastics, and they can be used to produce various products such as utensils, bags, furniture, carpets, films, bottles, cups, and packaging materials. They are less harmful than other plastics, which are generally made from fossil fuels (such as petroleum), and they produce lower amounts of GHGs than other plastics. Consequently, the use of bioplastics helps in the reduction of carbon emissions, which is not possible with fossil fuel-based plastics. Bioplastics are widely used in the Packaging sector as they are eco-friendly in nature and reduce the risk of food contamination.

1470.叶片塑化输运单元加工聚合物塑化性能研究
[橡胶和塑料制品业] [2013-12-15]
阐述了聚合物叶片注塑成型机中叶片塑化输运单元的工作原理并进行三维建模,应用流体动力学软件分析了该单元的塑化机理和拉伸流动特性。结果表明,该单元在锥形流道腔室内形成较大区域的拉伸流场,同时也有剪切流场和涡流的存在;该单元入口处呈现较大负压力,出口处呈现较大正压力,具有良好的正位移输运能力;叶片单元剪切流场区域所占流体区域的比例较小,与螺杆元件一样存在较强的剪切流场;叶片单元具有较强的拉伸作用,而螺杆元件在产生拉伸流场方面远低于叶片单元。因此,叶片塑化输运单元可以提高聚合物的塑化与分散混合性能,经过叶片注塑成型机加工的制品性能要优于螺杆元件加工的制品。
