随着科技进步和社会发展,保护资源已越来越引起人们重视。因而,以塑代钢、以塑代木,以塑代水泥等塑材应用日趋广泛。据预测,我国塑料制品产量到2000年和2010年将分别以年均8％和5％的速度递增,届时其产量分别达到2000万吨和4000万吨。塑料制品的火爆,自然为塑料机械带来巨大商机。因此,专家认为塑料机械行业是朝阳产业。随着化学工业应运而生的塑机行业,已显示出强大的生命力。它广泛应用于
With the advancement of science and technology and social development, the protection of resources has drawn increasing attention. Therefore, plastic materials such as plastic substitute steel, plastic substitute wood, and plastic substitute cement have become increasingly popular. It is predicted that the output of plastic products in China will increase at an average annual rate of 8% and 5% in 2000 and 2010 respectively, and the output of plastic products will reach 20 million tons and 40 million tons respectively. The popularity of plastic products naturally brings huge business opportunities to plastic machinery. Therefore, experts believe that the plastic machinery industry is a sunrise industry. With the emergence of the plastics industry, the plastics industry has shown strong vitality. It is widely used
