Abstract

Настоящее изобретение вообще направлено на процесс для отделения бывшего в употреблении полиэфира от различных загрязняющих его материалов и извлечения полиэфира. Изобретение может быть использовано для отделения бывшего в употреблении полиэфира от различных загрязнений, включая стекло, грязь, бумагу, металл, клей, краситель и т.п. Раскрытый процесс включает в себя несколько стадий, таких как стадия приготовления, в которой часть загрязнений может быть удалена из полиэфира, а также стадию проведения реакции, в которой часть полиэфира может быть омылена и загрязнения могут быть физически отделены от полиэфира. Помимо этого во время стадии проведения реакции некоторые трудно отделяемые загрязнения, такие как алюминий и поливинилхлорид, могут вступать в реакцию с образованием более легко отделяемой формы от полиэфира.The present invention is generally directed to a process for separating used polyester from various contaminating materials and recovering the polyester. The invention can be used to separate used polyester from various contaminants, including glass, dirt, paper, metal, glue, dye, and the like. The disclosed process includes several steps such as a preparation step in which a portion of the contaminants can be removed from the polyester, and a reaction step in which a portion of the polyester can be saponified and the contaminants can be physically separated from the polyester. In addition, during the reaction step, some difficult to separate contaminants, such as aluminum and PVC, may react to form a more readily separable form from the polyester.
