METHOD FOR TREATING EXTREMELY SMALL PARTICLES OF POLYETHYLENE TEREPHTHALATE |
摘要 |
<p>A method for treating extremely small particles of recycled polyethylene terephthalate comprises providing a quantity of RPET particles having an average mean particle size ranging from about 0.0005 inch to about 0.05 inch in diameter, heating the RPET particles to a temperature sufficient to cause at least a portion of the RPET particles to adhere to one another, and forming the adhered RPET particles into pellets, said pellets having substantially the same average surface-to-volume ratio as the bulk, un-adhered RPET particles.</p> |
