Recently, the PP3 unit of the polyolefin center of Yanchang Yunenghua Company produced polypropylene random copolymer pipe material H5416 qualified products
.
This is the company's first single-to-bimodal operation, and it is also another breakthrough
after the production of high-impact polypropylene and propylene copolymer transparent materials.
H5416 product is the high-end product with the lowest melting index at present, which has the characteristics of large viscosity and low melting index, and has extremely high
requirements for production accuracy.
In the process of conversion process, the technicians of the plant overcame the technical problems such as large fluctuation of reactor material level, unstable fluidization state, and sticky wall of the descending section, over-temperature agglomeration and discharge blockage of the reactor, and realized the unimodal switching and bimodal operation
.
It is understood that compared with traditional polypropylene, random copolymer polypropylene has good mechanical properties and impact resistance, and the prepared PPR pipe has the advantages
of stable performance, long service life, safety and environmental protection.
The product is a high-end green product, which can be applied to building heating system and drainage, industrial fluid transportation, agricultural irrigation and other fields
.
