Effect of Nanoclay on the Performance of Calotopis Gigantea Fiber Reinforced Thermoplastic Composites at Distinct Temperature
Abstract: Polymer-based nanocomposite is a developing subject that attracts many researchers due to its special qualities and versatility. Because the specific surface areas of nanofillers in nanocomposites are so high, it is much simpler to produce mechanical properties at the interface. Furthermore, a favorable interaction between the nanofillers and polymer matrix may manifest itself even at comparatively lower percentages of loading nanofillers. Thus, a smart, adaptive polymer nanocomposite material with the …

No Fine Concrete
Abstract: No-fine concrete has been in use in many countries over more than a century. Its higher porosity helps in percolating rain water directly to ground and thereby helps in recharging groundwater aquifer. In this study, 3 batches of no-fine concrete each with two different sizes of aggregate were prepared to find the mix that generated high compressive strength and study the effect of percentage of fine aggregate on the compressive …

Density-Based Separation and Polymer Type Verification of Mixed Post-ConsumerThermoplastic Streams: A Sequential Separation and Contamination Reduction Protocol for Secondary Polymer Supply Chains
Abstract: The separation of mixed post-consumer thermoplastic waste streams into polymer-type-specific fractions suitable for industrial reintegration is a fundamental chemical separation challenge in secondary polymer supply chains. Density-based separation, exploiting the characteristic density ranges of common thermoplastic polymers, remains the dominant first-stage separation technique in commercial recycling operations due to its low cost, scalability, and applicability across mixed waste stream compositions. This paper presents a sequential separation and contamination reduction protocol …

The Improvement of Polyvinyl Chloride Synthesis Using Different Approaches
Abstract: Polyvinyl chloride (PVC) is produced by the polymerization of the vinyl chloride monomer either by direct chlorination of olefins or by addition of hydrogen chloride to acetylene. The polymerization conditions are: heat, peroxides or oxidizing agents with basic structure as -CH2CHCl.CHCl-CH2.CHCl-. Polyvinyl chloride is a thermoplastic and its plasticity can be increased by incorporating ‘plasticizers’ of relatively low molecular weight organic materials during molding or extrusion. PVC has high hardness …
