根据我国塑料制品的发展趋势和产品结构调整的需要及我国塑机工业的实际情况,有关方面建议在今后一段时期内重点发展如下五个方面的技术: 一、高分子材料拉伸、复合、发泡技术设备 拉伸、复合、发泡是成型中极为重要的专项技术,涉及到原料配方、成型工艺、塑料机械和塑料模具。近年来,我国在一些领域已取得较大进展,如PUR反应注射,接近德国水平;发泡管材、发泡塑料 According to the development trend of China’s plastic products and product structure adjustment needs and the actual situation of China’s plastic machine industry, the relevant parties suggest that in the next period focus on the development of the following five aspects of technology: First, the polymer material stretching, composite, hair Foam technology equipment stretching, composite, foam molding is extremely important in the special technology, involving raw materials formulating, molding process, plastic machinery and plastic mold. In recent years, great progress has been made in some fields in our country, such as injection of PUR reaction, close to the German level; foamed pipe, foamed plastic
