The subject of this study is the application piezoelectric direct discharge (PDD) operated with nitrogen to control surface free energy (SFE) polymers. activation area, defined as area zone reaching SFE 58 mN/m for high-density polyethylene (HDPE) and poly (methyl methacrylate) (PMMA), characterized. For HDPE, was characterized a function distance from 1 16 mm, flow 5 20 SLM, treatment time 32 ...

Asphalt functions as an aggregate binder in the road pavement mixture. The rapid construction of roads causes need for asphalt to increase, while its availability is limited. government promoting use natural (Asbuton) alternative oil asphalt. However, performance from Asbuton not good. Uneven content and hardness are factors causing it be less effective a binder. It necessary improve by modifyi...

mechanical properties of wood/plastic composites manufactured by polyethylene and polypropylene blends (pp/hdpe) were studied. the sebs (styrene-ethylene butylene-styrene) and epdm (ethylene-propylene diene monomer) were used as compatibilizers to improve the compatibility and miscibility of the interface between hdpe and pp phases. the sawdust and polymers were compounded using an internal mix...

Plastic waste disposal is a significant environmental concern due to its low degradability and management practices, especially in developing countries. recycling considered the most effective method, which minimizes impacts. This paper discusses use of poly(ethylene terephthalate) (PET), high-density polyethylene (HDPE), polypropylene (PP) plastic as aggregates concrete industry by incorporati...

This paper presents the construction of multi-layer geosynthetic containment systems as part improvements to a stormwater management system mitigate groundwater contamination at coal combustion residual landfill in southeastern USA. The consisted lining perimeter ditch and sedimentation pond contain ash sediments minimize infiltration into groundwater. A composite liner comprised HydroTurf synt...

This study examined HDPE (high-density polyethylene) plastic waste as an added material for concrete mixtures. The selection of was based on its increased strength, hardness, and resistance to high temperatures compared with other plastics. It focused how can be used additive in increase tensile strength compressive strength. 156 specimens were identify the effect adding different percentages s...

Abstract Continuous drive friction welding (CDFW) is a solid-state joining procedure that can be used to join various similar and dissimilar materials. High-density polyethylene (HDPE) thermoplastic replace many traditional Utilizing experimental design procedures such as response surface method (RSM) reliable approach for determining the most significant process parameters optimizing desired r...

The objective of this study was to investigate the utilization waste tea wood fibers (WTWF) and effect maleic anhydride treated polyethylene (MAPE) in thermoplastic composites. For purpose, HDPE as matrix, WTWF lignocellulosic filler MAPE coupling agent were used. Six different composites produced by injection molding method; 0-15-30% ratio, with without MAPE. physical, mechanical, thermal morp...
