③ The gas phase method polymerizes in a gaseous state, generally using a fluidized bed reactor. There are two types of catalysts, chromium series and titanium series, which are quantitatively added into the bed from a storage tank, and high-speed circulation is used to maintain the fluidization of the bed and remove the heat of polymerization. The resulting poly is discharged from the bottom of the reactor. The pressure of the reactor is about 2 MPa, and the temperature is 85-100°C. The gas phase method is the main production line for low-density polymerization. The gas phase method eliminates the solvent recovery and polymer drying steps, and saves 15% of the investment and 10% of the operating cost compared with the solution method. 30% of the investment in the high-pressure method and 1/6 of the operating cost. As a result, it developed rapidly. However, the gas phase method needs to be further improved in terms of products and varieties. [7]

Recycled diphenyl is the main raw material for the manufacture of polyurethane elastomers, made of diphenyl Polyurethane products have been widely used in the production of polyurethane synthetic leather, artificial leather coating, polyurethane soft foam, rigid foam, etc., because they have shown high strength, low temperature resistance, low thermal conductivity and other good chemical properties. Used in building materials. The company recycles thousands of chemical products. Our company promises to recycle them quickly, at a reasonable price, and with professional, safe and environmentally friendly methods. Welcome your calls and sincerely look forward to cooperating with you!
