The future development trend of heat shrinkable casing polyolefin
A. At present, the development direction of olefin polymerization technology in China should start with reducing cost and improving product performance. Simplify process flow, develop and adopt new catalyst, reactor and process, improve equipment utilization rate, reduce energy consumption and material consumption. At the same time, to improve the physical and mechanical properties and processing performance of existing products, research and development of new varieties, new brands.
B. In the past, most of the technology imported by Chinese enterprises adopted the mode of general contracting by foreign investors and the introduction of complete sets of equipment. It is understood that when introducing the same type of production equipment, the investment in domestic construction projects is often higher than that in foreign countries. This is due to the fact that foreign countries generally only introduce software and key equipment that they cannot produce, and are contracted by their own engineering companies. It is suggested that China should adopt foreign methods to introduce technology in the future, which can not only reduce the investment cost by 20%~25%, but also speed up the improvement of the technical level of the team and enhance the ability of self-development.
C. Risk funds should be set up and increased in the polyolefin industry of heat shrinkable casing to speed up the process of transformation and industrial application.
D. Gradually change the idea of expanding reproduction mainly by pursuing quantity, growth rate and output value, and turn to the idea of connotative economic growth mainly by pursuing quality, efficiency, improving technology and management level.
E. Since there has been too much debt on investment in science and technology over the years, we should selectively increase investment in digestion, absorption, development and innovation of imported technology to ensure adequate funds for equipment, conditions and personnel training. At the same time, we should emphasize that we should do something to avoid decentralization.
F. Organize cooperation between industry, University and research, and tackle key problems jointly by research, design and production units. In 2000, Sinopec decided to jointly develop a new generation of 200 kt/a PP ring plant with international level by Shanghai Petrochemical Company, Beijing Petrochemical Engineering Company and Beijing Chemical Research Institute, and to list it as one of the core technologies, requiring it to be achieved in terms of product brand, catalyst, process flow, energy consumption, material consumption and investment cost. The same level of similar devices in the world. At present, the first 200 kt/a PP ring plant of the new generation has been completed and operated normally in 2003, and the second production plant will be completed and started in 2004, which is a new milestone in the development of polyolefin technology in China.
G. To formulate incentive policies adapted to the conditions of market economy and encourage relevant units to cooperate fully, especially in the use of information, large-scale instruments and pilot-scale equipment, so as to avoid "large and complete, small and complete" and waste human, material and financial resources.
H. Because the technology and management level of China's polyolefin industry is quite different from that of large foreign companies, we should strengthen opening up and adopt various cooperation modes with foreign countries, such as introducing technology, joint venture, joint development, introducing and training talents, in order to achieve mutual benefit and improve the level of China's polyolefin industry.
热缩套管聚烯烃未来的发展方向
a.当前中国烯烃聚合技术的发展方向应从降低成本和提高产品性能入手。简化工艺流程，开发并采用新型催化剂、反应器和新工艺，提高设备利用率，降低能耗物耗。同时，要提高现有产品的物理机械性能和加工性能，研究开发新品种、新牌号。
b.过去，我国企业引进技术大多采用外商总承包、成套装置引进的方式。据了解，引进相同类型的生产装置，国内工程建设投资往往高于国外，这是由于国外一般 只引进软件及自己不能生产的关键设备，由自己的工程公司总承包。建议我国今后引进技术也采取国外的方式，这样既可以降低投资费用20%~25%，同时又能 加快提高队伍的技术水平，增强自行开发能力。
c.热缩套管聚烯烃行业应设立和增加风险基金，以加速成果转化和工业推广应用的进程。
d.逐步改变以单纯追求数量、增长速度、产值的外延式扩大再生产为主的思想，转向追求以质量、效益、提高技术和管理水平为主的内涵式的经济增长方式的思想观念。
e.由于多年来对科技投入欠债太多，应该有选择地加大对引进技术消化、吸收、开发和创新的投入，保证在设备、条件、人员培养方面有足够的经费，同时又要强调有所为有所不为，避免力量分散。
f.组织产学研合作，科研、设计、生产单位共同攻关。2000年，中国石化决定由上海石化公司、北京石化工程公司和北京化工研究院共同开发具有国际水平的新一代环管200kt/a PP装置，并将其列为核心技术之一，要求在产品牌号、催化剂、工艺流程、能耗、物耗、投资费用等方面达到国际同类装置的相同水平。目前第一套新一代环管200kt/a PP装置已于2003年建成并运转正常，第二套生产装置也将于2004年建成开车，这是我国聚烯烃技术开发新的里程碑。
g.制订适应市场经济条件下的奖励政策，鼓励有关单位通力合作，特别是在信息、大型仪器与中试设备共同使用方面，避免各单位都搞“大而全、小而全”，浪费人力、物力与财力。
h.由于我国聚烯烃工业的技术、管理水平与国外大公司相差较大，应加大对外开放力度，与国外采取多种合作方式，如引进技术、合资办厂、共同开发、引进和培养人才等，以达到互惠互利和提高中国聚烯烃行业水平的目的。
