Tensile and impact test samples of ultra-high molecular weight polyethylene (UHMWPE), high-density (HDPE), their blends at various UHMWPE/HDPE ratios were prepared via compression molding injection for thermal, rheological, mechanical characterization. A twin-screw extruder with either a tapered die air-cooling or regular was used to compound extrude the materials prior pelletization molding. T...

It is a challenge to identify each phase in multi-component polymer system and uniquely determine the interfacial properties between different phases. Using atomic force microscopy nanomechanical mapping (AFM-NM) AFM-based infrared spectroscopy (AFM-IR), we phase, visualize structural developments, blend of three polymers: high-density polyethylene (HDPE), polyamide (PA6) poly(styrene-b-ethylen...

The present study investigates the effects of oxalic acid and 1-methylcyclopropane (1-MCP) treatments in combination with low-density polyethylene (LDPE) high-density (HDPE) on post-harvest storage litchi fruits. physicochemical properties, bioactive compounds, antioxidant activities, dismutase enzyme activity (SOD) treated untreated fruits were examined during 30 days at 4 ℃. most effective wa...

High density polyethylene (HDPE) / ultra high molecular weight (UHMWPE) blend is expected as an all-polyolefin recycle material that can achieve both mechanical properties and a continuous melt-mixing process. In order to improve the of polymer blends, optimal mixing required good dispersibility low degradation. this study, effect conditions on dispersion degradation behavior HDPE/UHMWPE blends...

Positronium (Ps) formation has been studied in high density polyethylene (HDPE) below and around gamma transition temperature (Tγ). The increase ortho-positronium (o-Ps) intensity (I3) with time due to trapped electrons at different rate discussed terms of possible models. Some calculation have performed find the thermal activation energy electrons.

In this study, municipal plastic waste is used in producing paving blocks. Binders the form of melted bottles (Polyethelene Terephthalate (PET)) and water sachets (High Density Polyethylene (HDPE) with river sand, were making Mix ratios; 1:1, 1:1.5 1:2 sand-plastic considered. Sand-cement mixes adopted as controls. 230mm x 140mm 55mm blocks cast, cured at ambient temperature tested for 72-hours...

Abstract This article presents the potential use of tree waste materials such as leaves (L), branches (B) and trunks (T) Azadirachta excelsa (Sentang) in production wood polymer composite (WPC). The WPC was fabricated from high-density polyethylene (HDPE) bonding matrix, maleic anhydride (MA) coupling agent, Sentang particles (L, B T) filler, prepared using twin-screw extruder followed by injec...

This work aims to produce a 3D-printable bio-based filament composed of high-density polyethylene (HDPE) and chemically modified cellulose nanofibrils. Printing using HDPE as raw material is challenging due its massive shrinkage warping problems. paper presents new method overcome those difficulties by enhancing the mechanical properties achieving better print quality. was achieved nanofibrils ...

Effectively consumed plastic waste is an emerging technical and social issue for Australia. Adding into construction material ensuring minimised impact to the mechanical performance of could bring significant benefits. In this study, was mixed cement-stabilised rammed earth (RE) brick manufacture. Techno framework consisting compressive strength test split tensile derivation structural assessme...

this study investigated the effect, on reactor performance and biomass retention inside the bed, of the material used to make the supports of anaerobic fixed-bed reactors. three inert supports of similar shape but made of three different materials polyvinyl chloride, polypropylene, high-density polyethylene were manufactured and used. all three supports had the same specific surface area but di...
