Alumina Ceramics:

Alumina ceramics use oxygen or peroxide as initiator to polymerize ethylene into low density polyethylene. Ethylene enters the reactor after two-stage compression, and is polymerized into polyethylene under the pressure of 100-300 MPa, temperature of 200-300°C and the action of initiator. The reactants are separated under reduced pressure, so that unreacted ethylene is recycled and melted. After adding plastic additives, the polyethylene is extruded and pelletized. There are two types of polymerization reactors: tubular reactor (tube length up to 2000 m) and tank reactor. The single-pass conversion rate of the tubular process is 20% to 34%, and the single-line annual production capacity is 100 kt. The single-pass conversion rate of the kettle-type process is 20%-25%, and the single-line annual production capacity is 180 kt. There are three types: slurry method, solution method and gas phase method. Except for the solution method, the polymerization pressure is below 2 MPa. The general steps include catalyst preparation, ethylene polymerization, polymer separation and granulation.
①The polyethylene produced by the slurry method is insoluble in solvents and is in a slurry state. The slurry method has mild polymerization conditions and is easy to operate. Alkyl aluminum is commonly used as activator, hydrogen is used as molecular weight regulator, and tank reactors are mostly used. The polymer slurry from the polymerization tank is passed through the flash tank and the gas-liquid separator to the powder dryer, and then to granulation. The production process also includes steps such as solvent recovery and solvent refining. Different polymerizers can be combined in series or in parallel to obtain products with different molecular weight distributions. ②Solution method The polymerization is carried out in a solvent, but both ethylene and polyethylene are dissolved in the solvent, and the reaction system is a homogeneous solution. The reaction temperature (≥140℃) and pressure (4~5MPa) are relatively high. It is characterized by short polymerization time and high production strength. It can produce polyethylene with high, medium and low density at the same time, which can better control the properties of the product; but the polymer obtained by the solution method has low molecular weight, narrow molecular weight distribution, and solid matter The content is low.
