In this research, the effect of wood species and particle size on mechanicalproperties of wood plastic composites (WPC) made of fir (Abies alba) and beech(Fagus orientalis L.) sawdust and high density polyethylene (HDPE) wereinvestigated. Wood plastic composite (WPC) were made with 30% HDPE in abatch process at 185˚C, at two particle sizes of 40 mesh and 80 mesh. Maleicanhydride polypropylene (...

Cross linking of high density polyethylene (HDPE) was first performed via high energy10 Mev electron beam (EB) irradiation. HDPE was also cross linked withDicumyle peroxide (DCP).The gel content of samples was determined by solvent extraction.Degree of cross linking was evaluated by hot set apparatus; as well .In order to clarify the effectof nature of cross linking, correlation of electrical p...

Single-wall fullerene nanotubes were converted from nearly endless, highly tangled ropes into short, open-ended pipes that behave as individual macromolecules. Raw nanotube material was purified in large batches, and the ropes were cut into 100- to 300-nanometer lengths. The resulting pieces formed a stable colloidal suspension in water with the help of surfactants. These suspensions permit a v...

The overall goal of this study is to propose a new approach simplify the recycling process for producing high quality material from waste beverage bottles and other sources at lower cost by using mechanical chemical reactions inside injection molding machines in one-step process. water soft drink are made PET material, while caps mainly HDPE. blends HDPE incompatible. resulted has poor properti...

The research was conducted in Bunati Village which is located Tanah Bumbu Regency. method used quantitative. Data collection carried out by measuring the levels of TSP, CO, and Fe clean water at 3 locations public health using a respiratory disorder questionnaire, skin disease peripheral oxygen saturation. results analysis location points showed that they were below environmental quality standa...

Bone, at the ultra-structural level, is a composite with mechanical properties that can be matched by man-made composites. It serves as the template for developing bone replacement materials. Research on biomaterials analogous to bone was started in the early 1980s by incorporating bioactive particles into biocompatible polymers to produce bone substitutes. Hydroxyapatite reinforced high densit...

A low-pressure plasma surface treatment of polymeric powders was carried out in a circulating fluidized bed (CFB) reactor (10 mm-I.D. × 800 mm-high) with CF4 glow discharge. The effects of solid circulation rate, treatment time and radio frequency (rf) power of plasma on fluorination of high-density polyethylene (HDPE) powders have been determined. X-ray photoelectron spectroscopy (XPS) and the...

The authors introduced waste plastic pyrolysis oil (WPPO) as an alternative fuel characterized in detail and compared with conventional diesel. High density polyethylene, HDPE, was pyrolyzed in a self-designed stainless steel laboratory reactor to produce useful fuel products. HDPE waste was completely pyrolyzed at 330-490°C for 2-3 hours to obtain solid residue, liquid fuel oil, and flammable ...

High-density polyethylene (HDPE) is one of the most popular plastics used in industry. Although it replaces many natural resources, due to low cost and easy processing, its ever-increasing wastes make harmful for environment. Thus, processes are order recycle it. In present study, properties recycled HDPE (r-HDPE) compared virgin investigated. The structural studies performed by X-ray diffracti...
