conductivity 95 96 alumina ceramic fixture sheet substrate Reputation depends on quality,  quality comes from Hard! Alumina Ceramics: Alumina ceramic gas phase method, ethylene polymerizes in gaseous state, generally a fluidized bed reactor is used. 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 ethylene is circulated to maintain the fluidization of the bed and remove the heat of polymerization. The polyethylene produced 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 most important method for the production of linear low-density polyethylene. The gas phase method eliminates the solvent recovery and polymer drying processes, and saves 15% of the investment and 10% of the operating cost compared with the solution method. It is 30% of the investment of the tradi…
