A successful trial production of new polypropylene thin-wall injection molding products of North China Petrochemical Company

On July 13, the inspection and analysis of HB66G, a new thin-walled injection molding product of polypropylene unit of the Fifth Joint Operation Department of North China Petrochemical Company, passed the inspection and analysis
.
A total of 483.
025 tons of new products were produced in this development, marking a successful development of the company's polypropylene thin-walled injection molding special materials
.

HB66G is a high melt flow rate thin-walled injection molded polypropylene product.
It has the characteristics of light weight, non-toxicity, corrosion resistance, good fluidity, easy processing and molding, and short production cycle.
It is widely used in food packaging, auto parts, home appliances , medical supplies and other fields, the market demand is increasing year by year
.

The key index of the melt index of the new HB66G product produced this time has reached a record high in North China Petrochemical's polypropylene series products
.
As another high-end product developed and produced by the polypropylene plant following the high-speed BOPP film special material HB28F, aluminized cast film HB37MF, and high-flow product fiber special material Z30S, it not only enriches the product structure of North China Petrochemical Company, but also strengthens polypropylene product market competitiveness
.

It is understood that Huabei Petrochemical Company adopts the new diether catalyst hydrogen adjustment method to increase the process route of rigid nucleating agent.
This method has higher requirements on the purity of propylene raw materials and hydrogen, and higher requirements on the measurement accuracy of various additives
.
Facing the challenge, the company set up a project research team at the beginning of the year, and worked with the youth innovation studio to prepare for the production of new products of the device
.
They conducted extensive research on polypropylene processing enterprises, conducted in-depth and detailed exchanges with their brothers, and understood the needs of downstream customers for new products.
In March, they signed a development technology agreement with the Petrochemical Institute to determine the research and development plan
.

Before the trial production of new products, the five joint operation department conducted in-depth research on the production process of polypropylene plants, conducted in-depth and extensive exchanges with experts from the imported catalyst supplier through video, and repeatedly docked the matters needing attention and details in the conversion process.

According to the communication situation, the operation department made more than ten revisions to the production conversion plan, and completed the preparation of the production conversion operation card
.

In June, the five joint operation departments carried out a series of preparations such as the cleaning of the reactor heat removal system, the oil washing and replacement of the main catalyst and auxiliary agent configuration system, the precise preparation of the special main catalyst and electron donor, and the blanking and maintenance of the granulation system.
And organize each team to study the trial production plan to ensure that every employee in the post masters the production plan and precautions, and understands the process technology and production points and difficulties
.

During the trial production stage, the management and technical personnel keep an eye on every step of adjustment, and the members of the innovation studio, technicians, and key personnel take the initiative to work overtime and enter the factory to participate in the trial production process, learning and summarizing to accumulate experience for future production
.
Under the close cooperation of various majors, the melt index analysis of the product passed the analysis on June 17, and the original product was cut into the warehouse.
On the 19th, the new product was packaged and put into storage, and the trial production of the new brand of thin-wall injection molding was successfully completed
.

The market price of special materials for thin-wall injection molding is higher than that of ordinary grades, and it is expected that the benefit can be increased by about 200-300 yuan per ton
.
Next, North China Petrochemical Company will adjust the technical parameters based on the analysis results of the finished products of the Petrochemical Institute and the Catalyst Patent Company, combined with the feedback from downstream users, summarize the experience and problems in the process of conversion, and produce higher quality products in the next production schedule.
