On July 31st, under the guidance of Yang Yexin, President of China National Petroleum Corporation (CNPC), the CNPC CO2-degradable plastics (PPC) project officially broke ground at the construction site. This milestone marks a significant step forward in the development of environmentally friendly materials and aligns with global efforts to reduce plastic pollution. The project, which began in 2004, focused on technology development, equipment research, market analysis, and product innovation. It leverages cutting-edge patented technology developed independently by the Changchun Institute of Applied Chemistry, part of the Chinese Academy of Sciences. The facility is designed to produce 3,000 tons of CO2-degradable plastic annually—making it the largest such plant globally, as the previous largest was only 1,000 tons. With an estimated total investment of RMB 152.2 million, the project is expected to be completed and operational by June 2008. It is a joint venture between CNOOC and the Changchun Institute of Applied Chemistry, located in the Dongfang Chemical City, a CNOOC-owned industrial park. China Oil One Construction Co., Ltd. will oversee the project’s construction and subsequent production management. The main raw materials used in the process are carbon dioxide from exhaust gas and propylene oxide. Under the influence of a catalyst, these two substances undergo copolymerization to create CO2-degradable plastic. This innovative material is fully biodegradable, breaking down into water and carbon dioxide without leaving harmful residues. It offers excellent transparency, degradability, high barrier properties, and good biocompatibility, making it suitable for various applications. It can be processed using injection molding, extrusion, and blow molding techniques, and has potential to replace many non-biodegradable plastics in fields such as medicine, food packaging, and agriculture. In recent years, CNOOC, in collaboration with Jilin Jinyuan North Science and Technology Development Co., Ltd. and Sun Yat-sen University, has made significant progress in developing products like medical materials, pharmaceutical packaging, films, foaming materials, and disposable tableware. They have successfully produced medical dressings, capsules, blister packs, and other essential items. These developments demonstrate the practical viability and environmental benefits of CO2-based plastics. By utilizing carbon dioxide as a raw material, this technology not only helps reduce "white pollution" but also lowers the demand for oil and gas resources typically used in traditional plastic manufacturing. As the world increasingly prioritizes sustainability, projects like this represent a promising direction for the future of materials science and environmental protection.

Fishing Magnets

Features

  1. Core Material: Neodymium (NdFeB), known for its high magnetic strength.
  2. Protective Coating: Typically nickel, zinc, or epoxy-coated for corrosion resistance and durability in water.
  3. Design: Often circular (pot magnet) with an eye bolt or loop for attaching ropes.
  4. Pulling Force: Ranges from 100 to over 1,000 pounds, depending on the magnet size and type.
  5. Shape Options:
    • Single-Sided Magnets: Magnetic surface on one side, ideal for beginners.
    • Double-Sided Magnets: Magnetic on both sides, offering a broader range of attraction.

Benefits

  1. Extreme Pulling Power: Able to retrieve heavy metal objects from underwater.
  2. Durability: Designed to withstand prolonged exposure to water.
  3. Versatility: Useful for both hobby and practical purposes.
  4. Easy Handling: Compact and lightweight designs with sturdy loops for easy attachment.

Common Applications

  1. Treasure Hunting: Searching for coins, jewelry, and other valuable metallic items.
  2. Environmental Cleanup: Removing ferrous debris like nails, hooks, or scrap metal from water bodies.
  3. Recovery Missions: Retrieving lost tools, keys, or equipment from water.
  4. Fishing Gear Rescue: Retrieving dropped fishing gear like lures or knives.

Safety Tips

  1. Use Strong Ropes: Secure the magnet with a durable, water-resistant rope.
  2. Handle With Care: Avoid pinching fingers between the magnet and metallic objects.
  3. Inspect the Magnet: Check for damage or corrosion regularly.
  4. Follow Local Regulations: Ensure compliance with rules regarding fishing in specific areas.

Popular Sizes

  • Small Magnets: For lighter objects and casual use (pulling force: 100–300 lbs).
  • Medium Magnets: Versatile and widely used (pulling force: 400–600 lbs).
  • Large Magnets: For heavy-duty applications and experienced users (pulling force: 800–1,200+ lbs).
