Yan 'an petrochemical co. Successfully converted to polypropylene medical

On March 30, the polypropylene unit of yan 'an petrochemical plant was successfully converted to a new brand of polypropylene fiber material (pph-y38), which indicated that the plant had the capacity of mass production of medical non-woven fabric material, and promoted the refining company to produce differentiated polypropylene products.

At present, the device runs stably.In the production of pph-y38 product, the system regulation of the extrusion granulator is the key point, and there are many related factors, which can easily cause shutdown.Yanhua joint second workshop party branch set up a party member project team to pool wisdom, collect relevant technical data, analyze and summarize the experience and lessons of other production enterprises, and make a detailed pilot production plan.

"In addition to the difficult control of the extrusion granulator system, the device equipped with a pelletizer is also very difficult to operate.On average, every 15 minutes, we took one sample and analyzed it to try to overcome the negative factors."Du xiong, director of yanhua joint workshop 2, said that during the trial production period, we controlled the whole process and accurately judged the possible problems, and successfully overcome the difficulties of product integration and large fluctuations of the main parameters of the extrusion granulation system.

It is known that pph-y38 products have the advantages of easy processing, small density, stable chemical properties, anti-mold and anti-bacteria, and can be widely used in the fields of textiles, clothing, medical and sanitary products.
