Item type:Publication, Preparation and characterization of the Na2Ti3O7: ABS/Na2Ti3O7 composites(2017-01-01); Titanate Ribbon (Na<inf>2</inf>Ti<inf>3</inf>O<inf>7</inf>) used in ABS plastic was synthesized to study the mechanical properties and to conduct test on the E-coli bacteria inhibition performance. The polymer blends of ABS/Na<inf>2</inf>Ti<inf>3</inf>O<inf>7</inf> by Na<inf>2</inf>Ti<inf>3</inf>O<inf>7</inf>, was synthesized through alkaline hydrothermal reaction with 0.5 grams of titanium dioxide as a precursor with 20 ml. of sodium hydroxide (NaOH) at the concentration of 10 molar under the alkalinity at 200°c for 24 hours. The study on the microstructure by scanning electron microscope revealed that the Layered structure was shaped as a complete ribbon. The mechanical testing activities on the E-coli bacteria inhibition polymer mixed ABS/Na<inf>2</inf>Ti<inf>3</inf>O<inf>7</inf>; it was found that the mechanical properties for ABS/Na<inf>2</inf>Ti<inf>3</inf>O<inf>7</inf>, The results showed that tensile modulus and tensile strength of blending Na<inf>2</inf>Ti<inf>3</inf>O<inf>7</inf> at 0.5 %wt was the highest. The result showed that E.coli could reduce up to 66.01%. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Novel foodstuff conveyor belts compound for energy saving: The effect of microwave pre-heating and mixed fillerson mechanical properties(2017-01-01); This research presents an effect of microwave power being utilized in preheating of a foodstuff conveyor belts compound (FCBc), with or without mixed fillers, and sulfur at different volumes of 1.0, 1.5 and 2.0 phr respectively. Prior to hydraulic molding press at 150 oC, an FCBc is preheated for one minute through an industrial microwave system at a frequency of 2.45 GHz along with microwave power of 340, 850 and 1,700 watts whereas the cure timeis a time 50%. The result shows that the FCBc with mixed fillers and 1.0 phr sulfur with microwave power at 340 watts demonstrates an effective crosslink between the rubber and the fillers which subsequently produces the FCBc that contains better mechanical properties, not only at the lower cost on raw material but also the curing time reduces to 40.20 % per production round. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Antibacterial and mechanical properties of the TiO2/ABS composites(2017-01-01); The aim of this present work is to enhance photoantibacterial performance on a surface of Acrylonitrile-Butadiene-Styrene (ABS) by mixing titanium dioxide (TiO<inf>2</inf>). The influences of different ratios for TiO<inf>2</inf> under UV light irradiation were investigated according to JIS Z 2801: 2010 standard. 0.5%, 1% and 2% TiO<inf>2</inf>/ABS were formed by melting process with internal mixer and compression molding process. E.coli were chosen as a model of bacteria. The best photoantibacterial activity was provided by 0.5% TiO<inf>2</inf>/ABS. The result showed that E.coli could reduce up to 46.95%. However, a higher amount of TiO<inf>2</inf> (i.e., 1% and 2% TiO<inf>2</inf>/ABS) obstructed the reaction, and E.coli was reduced to 42.6% and 36.08%, respectively. This was due to its aggregation observed from SEM image. For mechanical properties for TiO<inf>2</inf>/ABS, The results showed that tensile modulus and tensile strength of blending TiO<inf>2</inf> at 0.5 %wt was the highest but the tensile was decreased when increasing TiO<inf>2</inf> in polymer blended.
