An experimental and numerical study on the mechanical damping properties of styrene-butadiene rubber (SBR) composites with graphene nanoparticles (GNP) carbon black (CB) is presented in this paper. The were tested for such as hardness tensile strength. It observed that GNP & CB fillers have higher stiffness percentage elongation failure. A scale model chassis was subjected to forced vibrati...

Ceramifiable styrene-butadiene (SBR)-based composites containing low-softening-point-temperature glassy frit promoting ceramification, precipitated silica, one of four thermally stable refractory fillers (halloysite, calcined kaolin, mica or wollastonite) and a sulfur-based curing system were prepared. Kinetics of vulcanization and basic mechanical properties were analyzed and added as Suppleme...

A two-stage upflow anaerobic sludge blanket (UASB) and sequencing batch reactor (SBR) system was introduced to treat landfill leachate for advanced removal of COD and nitrogen at low temperature. In order to improve the total nitrogen (TN) removal efficiency and to reduce the COD requirement for denitrification, the raw leachate with recycled SBR nitrification supernatant was pumped into the fi...

Abstract The flow curves of polymers often reveal the onset melt instabilities such as sharkskin, stick–slip, or gross fracture, in order increasing shear rates. focus this work lies application Göttfert sharkskin option to investigation styrene-butadiene rubber (SBR) compounds. consists highly sensitive pressure transducers located inside a slit die capillary rheometer. This tool allows detect...

In this study, the upcycling and recycling applications for management of waste printed circuit boards (PCBs) were compared through sequential application Streamlined Life Cycle Assessment (S-LCA) Multi-Criteria Decision Making (MCDM) techniques. Upcycling determined as gold, copper-tin alloy, lead, copper recovery activated carbon production. And, portland cement, aggregate, sawdust, fiberglas...

Polymer modified concrete (PMC) consists of Portland cement concrete with a polymer modifier. Its advantages are proper bonding strength to substrate concrete, high tensile and flexural strength and low amount of shrinkage and permeability. Using PMC overlays can be considered as a method for preservation of damaged concrete structures due to their suitable performance and durability. In this r...

This study investigated the friction and wear pattern of silica-reinforced Styrene-Butadiene Rubber (SBR) in sliding with a steel blade indenter. The experiments were conducted using pin-on-disc tribometer at various applied loads examined under dry wet contact conditions. Analysis was focused on investigating coefficient length spacing. Related to identification, abrasion theory here. In addit...
