Biodegradation of Polyethylene Carbonate The Studies of Hyaline Globules in Hepatocellular Carcinoma 二氧化碳-环氧乙烷共聚物的微生物降解研究肝细胞性肝癌内透明球状小体
A series of low foam compound materials was prepared by hot pressing polyethylene blend resins filled with light calcium carbonate, powdered coal and short fiberglass and added compounding chemicals and then modified by reinforcing and filling. 以聚乙烯共混树脂为基体,填充轻质碳酸钙、粉煤灰及短切玻璃纤维,添加各种助剂,进行增强和填充改性,用热压成型方法制得低发泡系列复合材料。
