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.

A method and an apparatus are disclosed for analyzing an absorption filtering medium that filters volatile organic substances in a process gas in a dehumidification plant for dehumidifying polymer granules, with a fan that generates a flow of gas through the filtering medium, an analyzer for analyzing the concentration of total organic carbon, a sensor for detecting pressure downstream of the filtering medium, in which the state of saturation and/or the absorbent capacity and/or the deterioration over time of the filtering medium is determined by a comparison of the measured concentrations of the total organic carbon in the flow of gas upstream and downstream of the filtering medium.

An apparatus for degassing of gaseous components from at least one curable material, particularly a curable material for building a composite part, for example, a rotor blade for a wind turbine, is provided in an embodiment herein. The apparatus includes at least one degassing chamber having at least one inlet for introducing a curable material for building a composite part, the curable material containing gaseous components into the degassing chamber and at least one outlet for removing a degassed curable material from the degassing chamber and at least one mechanical splitting means adapted to mechanically split up gaseous components contained within the curable material so as to release the gaseous components from the curable material.

The present disclosure is directed to improved poly(arylene ether ketone) powders for use in laser sintering, powder coating, compression molding, or transfer molding.

The invention relates to a PET regranulate which, after modification of a granulated PET recyclate, has an intrinsic viscosity of at least 0.95 dl/g measured according to ASTM D 4603, preferably greater than 1.0 dl/g and particularly preferably between 1.1 dl/g and 1.7 dl/g and is suitable for the production of extrusion blow-molded containers.

In order to be able to operate a dust separator with or without a lower closure element (44), the closure element (44) is part of a separate closure unit (40) which is mounted under the dust separator if required. For this purpose, the dust separator, the closure unit (40) and optionally further components, such as a delivery flow generator, are kept available in a kit so as to be able to assemble the treatment unit as required. The dust separator can be operated in batches by means of the closure element (44).

The present disclosure relates to a facility for forming a wood plastic composite by mixing and extruding wood powder and a polymer resin. According to a facility of the present disclosure, in a process of forming a wood plastic composite, gas and water vapor contained in wood powder and polymer resin are efficiently removed, and thus, a coupling force between wood powder and polymer resin increases, and also, wood powder is uniformly dispersed inside polymer resin, and thus, physical properties of a wood plastic composite to be formed is not degraded, and in addition, since there is no stagnant section while molten liquid of wood powder and polymer resin passes through each apparatus in the facility, wood powder is prevented from carbonizing or polymer resin is prevented from solidifying, and thus, physical properties of the wood plastic composite to be formed are maintained constant.

An apparatus for melting and dispensing thermoplastic material is provided that includes an un-heated hopper having an inlet for receiving particles of a thermoplastic material and an outlet for discharging the particles and a heated manifold including at least one cavity formed therein and having an inlet and an outlet the inlet communicating with the outlet of the hopper for receipt of the particles from the hopper. The hopper is disposed external of the heated manifold. The heated manifold is effective for melting the particles into molten thermoplastic material therein. The apparatus further includes a pump having an inlet in fluid communication with the cavity. An outlet of the pump is in fluid communication with an inlet of a dispenser and an outlet of the dispenser is effective for dispensing the molten thermoplastic material therethrough.
