A METHOD FOR RECYCLING EXPANDED POLYSTYRENE
A process for manufacturing an expanded polystyrene foam article from used expanded polystyrene foam articles in combination with virgin polystyrene foam, the process comprising the steps of: stacking a plurality of individual used expanded polystyrene foam articles in a vertical block machine to occupy at least 20% of the internal volume in the block machine; conveying virgin polystyrene beads into the internal volume of the vertical block machine to occupy at least some of the remaining internal volume of the block machine by mixing the virgin polystyrene with the used stacked foam articles; and heating the internal volume of the block machine to a temperature of at least 75° C. by supplying pressurised steam into the heated internal volume of the block machine to fuse the virgin expanded polystyrene beads and the stacked expanded polystyrene foam articles to form the expanded polystyrene foam article.
Preparation method for surface molding film of PVC-based stone plastic composite board
The present invention discloses a preparation method for a surface molding film of a PVC-based stone plastic composite board, including: surface activation treatment of the PVC-based stone plastic composite board: preparation of an activated putty, coarse roughening of a substrate surface, application and solidification of the activated putty, and fine roughening of the substrate surface; preparation of a PMMA slurry; and surface film forming of the PVC-based stone plastic composite board. The PVC-based stone plastic composite board coated with a PMMA film is obtained by cold pressing and shaping in a mold, tightening up a clamp, solidifying at low temperature, treating at high temperature, cooling and demolding. The PVC-based stone plastic composite board coated with the PMMA film prepared by the present invention can avoid the problems of large investment in production lines and equipment and high production costs involved in the production of floorboards by the conventional surface printing and surface laminating technologies, to partially replace composite floorboards, stone, acrylic panels, and curtain wall panels, etc. currently popular in the market, and provide a new path for the high additional utilization of waste.
Heat-Shrinkable Polyethylene Films
A heat-shrinkable film comprises at least one layer made from a polymer blend comprising a virgin first polymer composition and at least 20 wt % of a recycled second polymer composition. The first polymer composition comprises at least 50 wt % of a polymer (a1) of ethylene and at least one alpha olefin having 5 to 20 carbon atoms, the polymer (a1) having a density from 0.918 to 0.945 g/cm.sup.3, a melt index from 0.1 to 2.5 g/10 min, a melt flow ratio from 25 to 80, a Compositional Distribution Breadth Index of at least 70%, and an averaged Modulus (M) from 20,000 to 60,000 psi.

Automatic sorting of polymer materials on the basis of the fluorescence decay time of the intrinsic fluorescence of the polymer
The invention relates to the identification of polymer materials on the basis of the fluorescence decay time of the intrinsic fluorescence of the polymer materials for definite sorting in a completely separated manner. The invention further relates to marking with fluorescent dyes, which, because of the specific fluorescence decay times of the fluorescent dyes, can further increase the sorting reliability by means of redundancy and can be used to identify particular batches.
PROCESS FOR MOULDING POLYMERIC FOAM CORE SANDWICH ARTICLES
A process for producing a polymeric article is provided that includes: sequentially filling a female mould (11) with a first, second, and third batches, wherein the first and third batches include first and third polymeric materials (1p, 3p), and the second batch includes a second polymeric material (2p) and a blowing agent (2b), closing the thus filled cavity with a lid (12) to form a mould defining a closed cavity (10c) of constant volume in time, heating the mould (10) to a processing temperature, to melt the first, second, and third polymeric materials (1p-3p) and to expand the second polymer agent by activation of the blowing agent, cooling and removing the lid (12) to open the cavity and extracting the polymeric article. At least the second polymeric material (2p) includes at least 50 wt. % of recycled polymer in the form of shredded flakes.
ORGANIC COMPOSITE MATERIAL AND A METHOD FOR MANUFACTURING THE SAME
The present disclosure describes a composite material and a method for making the composite material. The method includes mixing a copolymer binder with a thermoplastic biopolyester polymer (TBP) at a mixing temperature of 80-280° C. to create a polymer mixture; and mixing pyrolysized organic matter and an organic filler material with the polymer mixture to create the composite material. In an embodiment, the source of the pyrolysized organic matter is post-consumer food waste, and the mixing is performed by a shear mixer that is operated at 40-100 revolutions per minute (RPM). The composite material may comprise by weight at least 35% of a combination of the pyrolysized organic matter and the organic filler material.
Synthetic base and associated methods
Glycine is an organic compound that can be used in the making of a synthetic base that obviates all the drawbacks of strong bases such as sodium hydroxide. The new compound is made by dissolving glycine in water and adding calcium hydroxide at a molar ration of about 1:1. Next, sodium percarbonate is dissolved in the solution to produce the new compound, which can be referred to as glycine hydroxide.
