In this work, composites based on a hydride-forming fiber of multi-principal-component (MPC) Ti20Zr20Nb20V20Hf20 alloy, carbosil, dicumylperoxide and nitrile butadiene rubber (NBR) matrix were obtained. The prepared in three-stage process including the mixing elastomeric compounds via mill low-temperature vulcanization by heat pressing. Using dynamical mechanical analysis (DMA) differential sca...

 Background: The measurement data regarding the influent and effluent of wastewater treatment plant (WWTP) provides a general overview, demonstrating an overall performance of WWTP. Nevertheless, these data do not provide the suitable operational information for the optimization of individual units involved in a WWTP. A full-scale evolution of WWTP was carried out in this study via a r...

this study treats one important aspect of starch-filled rubber compounds which is their rheological behavior. starch-based sbr1712 masterbatches resulting from various formulations were prepared using a mini two roll mill and an internal mixer (plastograph brabender).the content in starch was varied from 0 to 50 phr. the effect of starch content on the rheological behavior was evaluated through...

Rubber industry has increased the requirements for quality and uniformity of natural rubber produced in Brazil. Technological properties of latex and natural rubber of clones GT 1, PB 235, IAN 873 and RRIM 600 [Hevea brasiliensis (Willd. Former Adr. de Juss.) Muell.Arg] were evaluated by standard methods of the dry rubber content (DRC%), percentage of nitrogen (N%) and percentage of ashes (ASH%...

The co-pyrolysis of various biomasses mixed with two types plastic waste was investigated in this study. Mixture M1 consisted 30% m/m styrene–butadiene rubber (SBR), 40% polyethylene terephthalate (PET), and polypropylene (PP). M2 PET, PP, acrylonitrile–butadiene–styrene copolymer (ABS). SBR, ABS, PP used study were from the automotive industry, while PET originated scrap bottles. Co-pyrolysis ...
