摘要： A preparation method of a high-rate foamed polylactic acid (PLA) sheet includes first-stage extrusion, second-stage extrusion, and foamed sheet extrusion. The method requires the following raw materials in parts by mass: 88 to 94 parts of PLA, 1 to 2 parts of a nucleating agent, 2 to 5 parts of a foaming agent, and 2 to 5 parts of an additive. The new method effectively solves the problems of low foaming rate, low strength, and the like in the industrial production using carbon dioxide, and a prepared PLA sheet with high foaming rate and excellent surface performance can be used in the fields of food packaging, disposable fully-degradable lunch boxes, and the like.

摘要： A method of increasing bubble stability of a needful high molecular weight bimodal high-density polyethylene resin in need thereof, the method comprising subjecting the needful high molecular weight bimodal high-density polyethylene resin to a determined amount of oxygen tailoring of the resin so as to independently increase both the resin's melt storage modulus G′ (at G″=3000 pascals) and complex viscosity ratio SH1000, and thereby make an oxygen-tailored high molecular weight bimodal high-density polyethylene resin having a targeted increase in bubble stability. The method uses a tailoring effective amount of molecular oxygen (O2) to achieve the desired oxygen tailoring. The method uses these advanced rheological properties from dynamic mechanical spectroscopy, but analyzes the data in a different way that is more sensitive to changes in resin composition and properties, and yet achieves a resin regime having a targeted increase in bubble stability.

摘要： Additive-polymer precursor materials for filaments (e.g., for three-dimensional (3D) printing) are provided, as well as methods of fabricating and using the same. One or more two-dimensional (2D) additive materials (e.g., nano materials, such as nanosheets) can be mixed with a polymer base to give an additive-polymer precursor composite material. The additive material can be dissolved in a first solvent to give an additive solution, and the polymer can be dissolved in a second solvent to give a polymer base. The additive solution can be mixed with the polymer base to give a mixed solution. Solvent casting can then be performed on the mixed solution to evaporate the solvent(s) and give the additive-polymer precursor composite material, which can have a layered structure.

摘要： A washing machine includes a casing, a tub, a drum, a circulation pump, an annular gasket connecting between openings of the casing and the tub and including circulation nozzles configured to supply water into the drum, and a conduit fixed to the gasket and guiding water to the circulation nozzles. The conduit includes an inlet port configured to receive water from the pump, a transport pipe configured to guide water from the inlet port to the circulation nozzles, and a supply ports configured to supply water to the circulation nozzles. A method for manufacturing a conduit includes positioning supply ports in a cavity defined at a first mold, forming a parison having a hollow opening by extruding a raw material, positioning the parison in the cavity, combining the first mold and a second mold, and injecting gas into the hollow opening of the parison.

摘要： A composite and method for producing the composite by incorporating wood or wood pulp fibres with a suitable thermoplastic polymer and coupling agent are described. Homogeneous, void-free transparent/translucent thermoplastic materials in the form of pellets, films or three-dimensional moldable products are produced. The wood pulp fibres can be discrete natural fibres, and flexible assemblies of nano to micro elements, e.g., assemblies of aggregated carbon nanotubes. It is also possible to use our vacuum-assisted co-extrusion process to produce hybrid composites comprising the wood pulp fibre and a further rigid fibre, like glass or carbon fibres, and a flexible fibre or fibrillar network, like cellulose fibres or cellulose filaments. The thermoplastic resin can be, but not limited to, polyolefins, like polypropylene or polyethylene, or polyesters, like polylactic acid, or co-polymers, like acrylonitrile-butadiene-styrene terpolymer.
