METHOD FOR RECYCLING PLASTIC
A method for recycling plastic such as plastic toys includes grinding the plastic into plastic pieces, sorting the plastic pieces based on type of plastic, sorting the plastic pieces based on colour, after sorting of the plastic pieces, shredding the sorted plastic pieces into plastic flakes, and processing the plastic flakes into a recycled good by means of rotational moulding. During the rotational moulding, a micronized plastic is added.
Softer Blended Nitrile Elastomeric Article
An elastomeric article is formed from a blend of nitrile rubber and polychloroprene rubber. The elastomeric article can be a glove, such as a medical exam glove. The elastomeric article is softer than a conventional nitrile elastomeric article. The elastomeric article is formed from a blended rubber latex emulsion of nitrile and polychloroprene. The blended rubber latex emulsion may be free of sulfur and vulcanization accelerators.
Method for preparing self-cleaning anti-icing coating based on brushlike organosilicon
The present disclosure relates to a method for preparing a self-cleaning anti-icing coating based on brushlike organosilicon. In this method, a brushlike organosilicon-modified polyurethane coating is prepared by subjecting a thiolactone, a diamine compound and monovinyl-terminated polydimethylsiloxane to a simple multi-component click reaction to obtain a dihydroxy-terminated block, and introducing the dihydroxy-terminated block into a polyurethane matrix.
METHOD OF PREPARING A BIODEGRADABLE FILM
Provided is a method of preparing a biodegradable film, which comprises the steps of coating a soluble supporting solution on a substrate, coating a prepolymer solution, pre-drying, crosslinking, and separating. With the technical means, the method can separate the biodegradable film from the substrate smoothly, thereby ensuring the film integrity of the produced biodegradable film.
METHOD FOR PRODUCING POLYIMIDE FILM
A method for producing a polyimide film includes: providing a polyimide coating solution; providing a high temperature resistant polyester substrate; and coating the polyimide coating solution on the high temperature resistant polyester substrate, so that a polyimide wet coating is formed on the high temperature resistant polyester substrate; implementing a first baking step, which includes: baking the polyimide wet coating at a first temperature of between 60° C. and 130° C. to remove a part of organic solvent in the polyimide wet coating; implementing a second baking step, which includes: baking the polyimide wet coating at a second temperature of between 140° C. and 220° C. to remove a residual part of the organic solvent in the polyimide wet coating, so as to form the polyimide film on the high temperature resistant polyester substrate; and separating the polyimide film and the high temperature resistant polyester substrate from each other.
NANOPOROUS COMPOSITE SEPARATORS WITH INCREASED THERMAL CONDUCTIVITY
Nanoporous composite separators are disclosed for use in batteries and capacitors comprising a nanoporous inorganic material and an organic polymer material. The inorganic material may comprise Al.sub.2O.sub.3, AlO(OH) or boehmite, AlN, BN, SiN, ZnO, ZrO.sub.2, SiO.sub.2, or combinations thereof. The nanoporous composite separator may have a porosity of between 35-50%. The average pore size of the nanoporous composite separator may be between 10-90 nm. The separator may be formed by coating a substrate with a dispersion including the inorganic material, organic material, and a solvent. Once dried, the coating may be removed from the substrate, thus forming the nanoporous composite separator. A nanoporous composite separator may provide increased thermal conductivity and dimensional stability at temperatures above 200° C. compared to polyolefin separators.
BIODEGRADABLE MEMBRANE
The invention relates to a biodegradable membrane on the basis of an organic-inorganic hybrid polymer, and to a process for producing same.
POLYAMIC ACID COMPOSITION FOR MANUFACTURING DISPLAY SUBSTRATE AND METHOD FOR MANUFACTURING SUBSTRATE FOR DISPLAY BY USING SAME
The present invention provides a polyamic acid composition, which, in a cured state on a substrate of amorphous or crystalline silicon, has an adhesion of 0.05-0.1 N/cm with the amorphous or crystalline silicon.
WATER-SOLUBLE FILM AND PACKAGE
There is provided a water-soluble film containing polyvinyl alcohol resin, wherein a ratio RSm (LD/TD) is 1.2 or greater and 2.5 or less, where the RSm (LD/TD) is the ratio of an average length RSm (LD) of roughness curve elements on at least one film surface in the longitudinal direction to an average length RSm (TD) of roughness curve elements on the same film surface in the transverse direction. This allows provision of a water-soluble film that can be suitably used for manufacturing a package with excellent uniformity of seal strength, even for manufacturing a package with excellent uniformity of seal strength during high-speed sealing; and a package using the film.
MEMBRANE FABRICATION OF QUATERNARY AMMONIUM FUNCTIONALIZED POLYPHENYLENE POLYMERS BY GREEN SUSTAINABLE ORGANIC SOLVENTS
The invention relates to the fabrication of membranes based on polyphenylene-based polymers—and more particularly, for example, quaternary ammonium functionalized polyphenylene-based polymers—utilizing a class of green sustainable organic solvents, such as cyclic ketones, by casting or coating for use in high temperature polymer electrolyte membrane fuel cells or water electrolyzers.
