In recent years, while the plastics industry is striving to develop, it has also been restricted by green environmental protection policies. Some highly polluting processes and products have been banned, and the recycled plastics industry is cautious in such a market situation. But in the future, the recycled plastics industry will still be a development trend, and its future is still bright.

Although environmental protection and rectification remained in 2014, there have been some deepening and changes since last year. In 2014, the management of Cixi City Government experienced major changes, and the post-remediation measures need to be further clarified, which made the industry confused about the next environmental protection action. A few manufacturers who are qualified for production are also very cautious, lest the government introduce other more stringent production regulations and rectification measures. In addition, according to industry sources, the rectification of the Yuyao market in 2014 will be more stringent. The rectification object is not limited to the processing enterprises scattered throughout the country, and the manufacturers involved in production in Yuyao Plastic City will also become the focus of rectification.

This wave of rectification may be carried out in March, and the industry is worried about this. At the same time, the scope of environmental protection has been continuously expanded. The rectification scope of the Jiangsu market has further expanded; the waste plastics manufacturers in the Wenzhou area of â€‹â€‹Zhejiang are currently being rectified due to water pollution problems. At present, some of the operators are looking for new production sites and workshops, and the start-up time is unknown. It can be seen that environmental protection and rectification in 2014 The momentum is even stronger, and the recycling market will face a new round of rectification and ban.

Under the influence of multiple obstacles such as upstream and downstream negative, environmental protection, rectification and deepening, the enthusiasm of regenerative manufacturers to enter the market has been greatly suppressed, resulting in a shortage of supply in the field, lack of trading, and the profits of the industry are difficult to guarantee, and the situation is becoming more and more embarrassing. At present, recycled plastics have become a new trend in the plastics industry, but there are certain difficulties in obtaining recycled plastics, and the number is still limited. However, if each side of the supply chain can communicate with each other and work together, the packaging industry will use recycled plastics in 2014. The rate will definitely increase.

DUPLEX STAINLESS STEEL

Duplex Stainless Steels Available

Yuhong Group supplies LDX2101, 2205, Ferralium 255, Zeron 100 and LDX2507 in the form of plate, sheet, strip, bar, pipe, tubing, pipe fittings, flanges and weld wire.

Duplex Stainless Steel Overview

Duplex Stainless Steels, also referred to as austenitic-ferritic stainless steels, are a family of grades with about equal proportions of ferrite and austenite. These steels have a duplex microstructure which contributes to their high strength and high resistance to stress corrosion cracking. Due to their high content of chromium, nitrogen and molybdenum, duplex steels offer good resistance to local and uniform corrosion. Duplex stainless steels have good weldability.

Today, modern duplex stainless steels can be divided into three groups:
Lean Duplex such as LDX2101
Standard Duplex such as 2205, the work-horse grade accounting for more than 80% of duplex usage
Super Duplex such as Ferralium 255 and Zeron 100 and LDX2507

Of the duplex grades, duplex 2205 is the most widely used. However, the super duplex steels like ZeronÂ® 100 and LDX2507 are excellent for servicing severe corrosive environments, such as offshore and marine applications. Lean duplex 2101 is available as an economic alternative to 300 series stainless steels.
