With its market demand expansion and increased application areas, products of wood-plastic composite (WPC) have been developing growing rapidly in many countries over the last decades. This paper attempts to investigate effect wood species that are waste from furniture industries on performance composites (WPCs). The samples were prepared by varying flour at 30wt% mixed with 70wt% HDPE (High De...

The article discusses the results of experimental studies on course pyrolysis oil injection through high-pressure injector a direct-injection engine. used for tests was derived from waste plastics (mainly high-density polyethylene—HDPE). This then distilled. also describes production technology this laboratory scale. It presents chemical composition raw and after distillation process using GC-M...

This study investigated on the co-pyrolysis of microalgae Chlorella vulgaris and high-density polyethylene (HDPE) waste mixtures which was performed with three types catalysts, namely limestone (LS), HZSM-5 zeolite, novel bi-functional LS/HZSM-5/LS. Kissinger-Kai (K-K) model-free method coupled Particle Swarm Optimization (PSO) model-fitting using thermogravimetric experimental data. A global s...

Soil fumigation is an important component of U.S. agriculture, but excessive emissions can be problematic. The objective of this study was to determine the effects of agricultural films (e.g., tarps) on soil fumigant atmospheric emissions and spatiotemporal distributions in soil, soil temperature, and plant pathogen control in the field using plastic films with various permeabilities and therma...

A low cost and low dielectric loss zirconium silicate (ZrSiO4) reinforced HDPE (high-density polyethylene) composite has been developed for antenna applications. The 0-3 type composite is prepared by dispersing ZrSiO4 fillers for various volume fractions (0.1 to 0.5) in the HDPE matrix by the melt mixing process. The composite shows good microwave dielectric properties with a relative permittiv...

To modify water absorption properties of bamboo fiber (BF) and high density polyethylene (HDPE) composites, heat treatment of BFs was performed prior to compounding them with HDPE to form the composites. The moisture sorption property of the composites was measured and their diffusion coefficients (Dm) were evaluated using a one-dimensional diffusion model. Moisture diffusion coefficient values...

Plastic waste management has become a pressing global issue. A viable and sustainable alternative to incineration is the conversion of polyethylene into chemicals or fuels by through hydrocracking. To improve catalytic performance during hydrocracking, bifunctional catalysts are required, in which zeolite imparts acid function, metallic function provided noble transition metal, such as nickel. ...

A melt flow indexer (MFI) was used to investigate high-temperature transitions in melts of high-density polyethylene (HDPE). The MFI data were obtained in the range 190–230°C. These transitions were found in the MFI at about 210 and 225°C and reproduced in a Haake melt blender. Polystyrene was used in the blender experiment to demonstrate typical amorphous behavior. For HDPE melts, the MFI–temp...

High-density polyethylene (HDPE) piping has been used in place of steel alloys in the petrochemical, power, and mining industries due to its exceptional resistance to corrosion and erosion. Recently, HDPE has also been used for nuclear safety-related cooling water applications. The application of nuclear quality assurance requirements creates reasonable assurance that the production fusion join...

The Balgrist hip socket, initially made entirely of HDPE (high molecular weight polyethylene), now made of outer titanium alloy shell that faces the bone of the acetabulum has been in clinical use for 10 years. The purpose of this presentation is to illustrate the biomechanical principles that have governed this unique design and to present the clinical results that we have obtained until the e...
