摘要:
The present invention relates to a new composite for manufacturing structural elements characterized in that it comprises at least two thermoplastic polymers from recycled materials and at least one filler selected from mineral fillers and reinforcing fibres, or any combination thereof. A second object of this invention will be, likewise, a structural element characterized in that it comprises said composite, as well as the method for manufacturing the same.
摘要:
Barrier films are prepared from a blend of two high density polyethylene blend components and a high performance organic nucleating agent. The two high density polyethylene blend components have substantially different melt indices. Large reductions in the moisture vapor transmission rate of the film are observed in the presence of the nucleating agent when the melt indices of the two blend components have a ratio of greater than 10/1. The resulting barrier films are suitable for the preparation of packaging for dry foods such as crackers and breakfast cereals.
摘要:
In a method for producing composite materials, preferably plastics, metered amounts of additional agents, preferably nanopowders and/or nanofibers, are admixed during production to form a homogenous matrix of the composite material to be produced. The additional agents are present at least partially in an agglomerated state before being admixed and are subsequently deagglomerated and added to the coating or to the plastic being processed to form the homogenous composite material. Said method is also suited for admixing metals during spray compacting or powder coating.
摘要:
Disclosed herein is a method of manufacturing a flexible display substrate having low moisture permeability and low oxygen permeability, the flexible display substrate being mounted with an organic device. The method includes the steps of uniformly dispersing nanosized or microsized particles in a molten polymer matrix (S101) forming the molten polymer matrix dispersed with the nanosized or microsized particles into plate-shape molten polymer, and then extruding the plate-shape molten polymer between two extruding rollers to form a polymer or plastic sheet (S103), thereby orienting the nanosized or microsized particles in parallel with a surface of the polymer or plastic sheet, stretching the polymer or plastic sheet between the glass transition temperature and the melting point to form a polymer or plastic film (S105), thus improving exfoliation of the nanosized or microsized particles, and orienting the nanosized or microsized particles to a higher degree in parallel with a surface of the polymer or plastic film, coating the polymer or plastic film with an organic film to flatten a surface of the flexible display substrate (S107) and performing heat treatment to cure the organic film (S109).
摘要:
A process for producing a solid dispersion of an active ingredient which comprises feeding the active ingredient and a matrix-forming agent to an extruder and forming a uniform extrudate, wherein the extruder comprises at least two rotating shafts (2), each of the shafts (2) carrying a plurality of processing elements disposed axially one behind the other, the processing elements defining (i) a feeding and conveying section (A), (ii) at least one mixing section (B), and (iii) a discharging section (E), wherein the processing element(s) defining the mixing section (B) comprise(s) a mixing element (11, 12, 13) that is derived from a screw type element ( figure 2 ).
