Polypropylene high temperature resistant film production line (BOPP-4) project commissioning trial production
On December 18th, the high temperature resistant polypropylene film production line for capacitors independently designed and constructed by our company successfully entered trial production after a single feeding, which marked the initial success of the project construction, and the company's electrical film production and core technology once again achieved a leap forward.
Polypropylene capacitor film is the leading product of our company's core industrial chain of "electrical trimembrane". At present, the company maintains the scale advantage of the world's largest output of this product. In order to effectively ensure the stability of product quality and complete varieties with more detailed specialization, so as to enhance the competitiveness of products, The company invested 178.6 million yuan to start construction of the fourth film drawing line -- polypropylene high temperature resistant film production line for capacitors. After the completion of the project, the company's annual polypropylene film production capacity reaches 12,000 tons, and continues to lead the national electrical film manufacturing industry.
Different from the previous three film drawing lines, the new line has changed the previous way of providing complete sets of equipment and technology by foreign suppliers, and the company undertakes the overall design, planning, organization, installation and debugging and other key links in the construction. This is a bold attempt based on technical experience, and it is also the first one in the domestic industry. The company will be the entire production line for equipment bidding, select the best key equipment, in order to absorb the advantages of domestic and foreign equipment manufacturing enterprises, through reasonable allocation, recombination of a high level of comprehensive performance of the production line, this not only greatly reduces the cost of production line construction, but also enables the company to further grasp the first-hand information of various core technologies of electrical film production line. The company's capacitor film manufacturing level has been strongly promoted again.
Since the installation of the equipment started on August 16, the project staff has overcome various difficulties and set new records. The installation time of each unit has been reduced from the previous time. In the construction of the project, the arrival of the horizontal and vertical pulling equipment of DMT Company in France was delayed by 2 months, which brought more difficulty to the installation work which was already tight in schedule. The project department, while stepping up coordination, resolutely adjusted the installation plan, broke the established procedure of the installation from the horizontal and vertical pulling to the two ends in the past, and changed it from the two ends to the middle, and the installation of each unit equipment advanced in tandem. The staff worked together to overcome the difficulties, and raced against time to speed up the progress while maintaining the quality and quantity. Finally, they regained the precious time lost and completed all the installation work according to the requirements of the construction period.
