Recently, Sichuan Petrochemical has successfully developed and produced 5,000 tons of tobacco film material HF42B. The transfer of tobacco film, whether it is switching time, the transition material production or product quality, all the important indicators are in the domestic advanced level of similar devices, petrochemical people Actual actions To implement the spirit of the 19 National Congress and base on posts to devote energy to society.
HF42B is a key project of new product development of Sichuan Petrochemical Polypropylene Plant in 2017. HF42B is mainly used in high-grade film such as tobacco film. It has high requirements on products such as low ash, high definition and high stability. It requires a substantial increase in catalyst activity in production. Under the premise of adapting to high-speed drawing, the tensile yield strength and flexural modulus are increased, and higher requirements are put forward in all aspects of production.
In the course of this conversion, the PP plant manager proposed the goal of "promoting quality with fine operation", and succeeded in the product upgrading of the polypropylene film with the fine and high requirements. 'Outstanding quality, high quality Win word-of-mouth ', polypropylene plant personnel to optimize the operation of various processes, the quality of all aspects of the pass, strict control of the indicators of polypropylene film conditions, to ensure that the whole process of polypropylene product quality control safely, the quality indicators All of them reached the expected goal. Among them, flexural modulus was 1430 MPa, tensile yield stress was 33.9 MPa, and haze was 4.2%, both of which were at the advanced level of similar domestic products.
