The present invention relates to a method for manufacturing thermoplastic polymer particles, and the thermoplastic polymer particles, the method comprising the steps of: (1) extruding a thermoplastic polymer resin through an extruder; (2) spraying the extruded thermoplastic polymer resin through a nozzle and then spraying a gas to the sprayed thermoplastic polymer resin through a plurality of sprayers so as to granulate same; and (3) cooling the granulated thermoplastic polymer resin.

Techniques involve cleaning a polymer melt, which allow volatile foreign substances and solid foreign substances to be removed from the polymer melt. Such techniques involve a filter element and a vacuum of a vacuum chamber. The polymer melt is fed through the filter element into the vacuum of the vacuum chamber, The filter element binds the solid foreign substances and the vacuum chamber takes up the volatile foreign substances.

The present invention provides methods for preparing the nut waste composites from a nut waste component, one or more binders, and an oil using a compounder/extruder.

A high temperature resistant polyimide film and its preparation method. The present invention relates to a polyimide film and its preparation method and solves the problems of honeycomb's and skin panel's core adhesive-polyimide film with insufficient heat resistance, no climbing of bonding core structure and adhesive fillet formation. The high temperature resistant polyimide film is made by polyimide solution, inorganic filler modifier and interface coupling agent by the steps of: under specific temperature and stirring conditions, adding inorganic filler modifier and interface coupling agent to polyimide solution, stirring to obtain the adhesive agent; filtering and degassing the adhesive agent, casting to a stainless steel drum with carrier cloth and release paper to obtain a self-supporting film; then heating and annealing to obtain the final polyimide film. The present invention is applied to high temperature resistant polyimide film and its preparation method.
