According to the work arrangement of Sinopec Group Headquarters, Shijiazhuang Refining and Chemical Company broke the routine and organized urgently to tackle key problems.
The first production of polypropylene high-melt index melt-blown base material was successful.
After testing, all the indicators of the product met the requirements

According to the work arrangement of Sinopec Group Headquarters, Shijiazhuang Refining and Chemical Company broke the routine and organized urgently to tackle key problems.
On March 4th, the first batch of products have been tried out for downstream meltblown non-woven fabric processing enterprises, marking the further development of the third-generation loop process technology potential with Sinopec's intellectual property rights, becoming the first set of domestic melt-blown non-woven fabrics capable of producing melt-blown non-woven fabrics.
The melt index of polypropylene is the most basic indicator of polypropylene products.
The melt index determines the variety and performance of downstream products.
The higher the melt index, the greater the selection width (dimension) of the products produced by downstream users, and the less additives are added when the meltblown material used in the production of masks is used.
, less odor, more environmentally friendly and low cost
.
The melt index of polypropylene is the most basic indicator of polypropylene products.
The production capacity of the stone refining polypropylene plant is 200,000 tons/year.
It is the first polypropylene production plant in China that adopts Sinopec's independent intellectual property rights and the third-generation liquid phase loop technology.
It can produce a variety of food-grade (lunch boxes), Medical (syringe, baby equipment, spunbond non-woven raw materials) green products
.
The production capacity of the stone refining polypropylene plant is 200,000 tons/year.
Shilian accepted the emergency trial production order of Sinopec Chemical Division.
That night, the company organized two special production meetings to study the production feasibility plan and a series of production preparations
.
Shilian accepted the emergency trial production order of Sinopec Chemical Division.
It is the first time that the company uses plasticizer-free HR catalyst to produce high melting index polypropylene.
There is no experience to learn from.
With the strong support and help of experts from Beijing Chemical Industry Research Institute, the two parties have further discussed and improved the production plan, key control data and operating parameters.
, and opened a WeChat hotline with experts to guide production in a timely manner
.
It is the first time that the company uses plasticizer-free HR catalyst to produce high melting index polypropylene.
After full preparation, the plant entered the production stage on February 27.
The employees strengthened the control of operation details, and the technicians strictly controlled the quality and key points of operation, and worked steadily and steadily to ensure the stable production of the polypropylene plant

In the early morning of February 29, the production task of 190 tons of high melting index polypropylene powder, that is, meltblown base material, was completed.
The measured melting index exceeded 400g/10min

The success of this emergency production of Shilian has provided technical support for the in-depth development and application of Sinopec's third-generation loop pipe process technology.
The polypropylene has no plasticizer and high melt index, so the subsequent processing is more economical and environmentally friendly
