Tianjin Petrochemical focuses on green environmental protection and refers to high-end polyester

Recently, Tianjin Petrochemical's 120-ton all-titanium environmentally friendly polyester chip TFT500 was shipped to the European Union, Southeast Asia and other regions after being shipped in Tanggu Port, once again helping enterprises create benefits
.

As the first domestic enterprise to produce antimony-free semi-gloss polyester chips on a 100,000-ton/year polyester continuous polymerization production line, in recent years, Tianjin Petrochemical has focused on green environmental protection and pointed to high-end polyester, and gradually developed a green polyester product.
Road of development
.

In the first half of this year, sales of differentiated polyester products exceeded 69,000 tons

The titanium-based catalyst was developed by the Tianjin Petrochemical Research Institute and has independent intellectual property rights of Sinopec.
Because it does not contain heavy metal antimony, it has excellent environmental performance and is favored by the market
.

The all-titanium environmentally friendly polyester chip TFT500 is the "star product" produced by Tianjin Petrochemical using titanium-based catalysts.

The "overseas journey" of all-titanium environmentally friendly polyester chips has not been smooth sailing
.

Since the product opened to the international market, European customers have put forward higher environmental requirements for environmentally friendly polyester particles

With the joint efforts of relevant departments of the company, the sales of all-titanium products have gradually opened up
.

Next, how to make products with lower cost and better quality has become the direction of Tianjin Petrochemical's new polyester product research and development

"All-titanium products are only the primary version, and the low melting point series are upgraded versions with higher added value
.

" According to Zang Guoqiang, a technician at the company's research institute, after many studies and tests, they focused on low-melting products

Low-melting polyester chips are often used to produce skin-core composite short yarns and filaments, etc.
They are the raw materials for making filters, clothing, shoes and hats, sofas, bedding and medical and sanitary products, and have a good market prospect
.

　　In 2019, the polyester research team used titanium catalysts to develop antimony-free low-melting chip TFM700 at 220 degrees Celsius after many experiments, successfully replacing foreign imported products
.

On this basis, in 2020, combined with market demand and actual installations, they will produce 180 degrees Celsius, 200 degrees Celsius, and 220 degrees Celsius on a 100,000-ton/year polyester continuous polymerization production line for the first time through one-time conversion and segmented control in 2020.

　　"It used to be one product at a time, but this time it is to develop and produce three products continuously
.

It is the first time for Tianjin Petrochemical's polyester plant to challenge such a difficult differentiated production, and it is rare in the industry

　　After the initial test was successful, this year, the team focused on the serialization and large-scale production of low-melting polyester products
.

This time, they changed their previous conventional sampling methods.

　　With the support of full and accurate data, the technical personnel carried out subversive optimization and adjustment of the key process parameters, and received good results
.
Compared with 2020, the transition material has been reduced by 125 tons, the key indicators of each brand have changed more smoothly, and the appearance and color of the new product has increased by 1.
5 units, and the quality stability is stronger, which is well received by the market
.
