China Petrochemical News Network reported that Baling Petrochemical Rubber Department seized market opportunities, optimized the supply of raw materials, and increased the total production volume.
In the first five months of this year, the cumulative production of thermoplastic rubber SEBS exceeded 33,200 tons, an increase of 22.
6% year-on-year, of which production in May More than 7,500 tons, a record high
.
SEBS is a basic thermoplastic rubber material obtained by selective hydrogenation of a styrene/butadiene block copolymer with a specific structural design.
It has the characteristics of aging resistance, safety, non-toxicity, and environmental protection.
It is mainly used for drug packaging and medical infusion equipment.
, Large-span lubricants, food packaging, wires and cables, sealing materials, plastic modification, high-grade asphalt modification and elastic materials in contact with the human body
.
Baling Petrochemical is the first domestic enterprise to adopt independent innovative technology to realize the industrialized production of SEBS.
With the new SEBS plant with an annual output of 50,000 tons and put into operation in February this year, the company’s rubber department currently has an annual production capacity of 100,000 tons of SEBS and has 4 production lines.
Can produce more than 10 varieties (brands) of products
.
The SEBS device with an annual output of 20,000 tons in the Rubber Department is expanded from a 10,000-ton-class device
.
Since the beginning of the year, SEBS installations (workshops) have implemented various technological transformations, optimized processes and equipment, and checked and rectified hidden dangers through daily dynamic monitoring, encrypted inspections of key parts, and real-time monitoring of production processes to ensure stable and high-load operation of the installation
At the same time, the process operations of the front and rear sections of the SEBS device are closely connected.
The processing capacity of the refining device will be checked immediately after the shifts of the previous section, to ensure the supply of cyclohexane, and focus on product quality, and adjust production according to the indicator trend in time; the latter section focuses on equipment maintenance Maintenance, check and clean the screens, filters, and sieving machines of the 4 grinding systems one by one to prevent the powder from clogging
.
In May, the SEBS output of this device exceeded 2500 tons, an increase of 3% from the historical record
The SIS device (workshop) of this department has two sets of SEBS devices with an annual output of 30,000 tons and a newly-built annual output of 50,000 tons
.
In order to open the old devices and "smooth" the new ones, they insisted on making progress while maintaining stability, focusing on standardized operations, solidifying the product brands of each production line, and reducing the production consumption of different brands of products
At the beginning of the start-up of the solvent purification tower of the new SEBS unit, the product quality fluctuated due to the influence of the solvent
.
The follow-up device has launched key research, optimized the overall process, and realized the stable extraction of refined solvents.
