PURIFICATION METHOD AND EQUIPMENT FOR POLYETHYLENE WAX |
摘要 |
PURPOSE: Provided are a purification method and an equipment for polyethylene wax which is useful as a coloring agent and an lubricant. CONSTITUTION: The purification method of lower polyethylene wax generated form the polymerization of polyethylene slurry, by crystallization comprises the steps of: inserting lower polyethylene wax into a crystallizer; heating the lower polyethylene wax in the crystallizer up; cooling it to crystalize the inside of the crystallizer; melting produced crystals at 80-140 deg. C; and obtaining high purity of crystals therefrom.
